MINDFULNESS, ANXIETY, AND PSYCHOSIS
Abstract
Mindfulness is described as “paying attention in a particular way: on purpose, in the present
moment, and non-judgmentally” (Chadwick, Taylor, and Abba p 351, 2005). This study
purposes that mindfulness based training will have a greater effect in reducing anxiety in patients
that are in acute inpatient facilities who are experiencing psychosis better than the facilities
standard training which is rational behavior therapy based. Thirty participants will be asked to
join the study in which fifteen of the participants shall receive mindfulness training while the
other fifteen participants will receive the standard hospital therapy. The participants will be
asked to rate their anxiety levels using State-Trait Anxiety Inventory (STAI) and Beck’s Anxiety
Inventory (BAI) prior to their first group and after their last group has been administered. It is
expected that the mindfulness group will experience greater reduction in anxiety symptoms as
reported by BAI and STAI. This study can help influence future directions in therapy in acute
inpatient facilities.

MINDFULNESS, ANXIETY, AND PSYCHOSIS
Introduction
Davis, Strasburger, and Brown (2007) used mindfulness training to see if there would be
a reduction in anxiety as it relates to patients who were diagnosed with the DSM IV-TR
definition of schizophrenia. They found that mindfulness training helped to reduce anxiety in
participants with schizophrenia in comparison to intensive therapy (Davis, Stasburger, and
Brown 2007). Mindfulness is defined as “purposefully paying attention in each moment to all
life experiences, regardless of how ordinary” (Davis, Strasburger, and Brown p. 24, 2007).
Although, numerous studies have looked into mindfulness as a way to cope with both
psychological and non-psychological distress, many fail to see how mindfulness can improve the
quality of life in those with psychosis in acute inpatient facilities (Carmody and Baer 2008).This
study seeks to explore mindfulness training and its effects on reduction of anxiety in acute
inpatient, patients that are experiencing psychosis. It is expected that mindfulness training will
help reduce anxiety and increase mindfulness in those participants that are given mindfulness
training.

MINDFULNESS, ANXIETY, AND PSYCHOSIS
Review of Literature
More holistic approaches have been taken in recent years to improve the quality of life in
those experiencing psychosis (Lukoff, Wallace, Liberman, and Burke 1986). Holistic approaches
tend to involve more than just psychoeducational therapy. The idea is to continue the already
existing continuation of mind and body. Lukoff and colleagues (1986) used a holistic approach
to see if there was a significant reduction in stress, in individuals with schizophrenia. The
comparison group of social skills training and holistic approach to stress reduction showed no
difference in prevention of relapse back into a hospital setting.
From holistic approach, the idea of positive psychology arose as a method to enhance
well-being, both psychological and physical. Positive psychotherapy (PPT) was developed to
increase positive emotion, engagement and meaning (Seligman, Rashid, and Parks 2006).
Positive psychotherapy has been used in various clinical settings and parallels mindfulness in
that it teaches the individual to focus on their well-being and engagement with their body.
Positive psychology interventions are effective in enhancement of subjective well-being,
psychological well-being and reduction of depressive symptoms (Bolier et al 2013). Thus, a
focus on well-being will be beneficial for individuals with psychosis.
It is also important to consider how holistic approaches can be used to prevent
hospitalization. In research conducted by Drvaric, Gerristen, Rashid, Bagby, and Mizrahi (2015)
defined resilience as the ability to adapt to stress and adversity. The study shows that
interventions addressing well-being as it relates to resilience can help people at clinical high risk
for developing psychosis. Well-being is important focus for psychosocial interventions. Thus, it
is important to begin prevention mechanisms in those that are more likely to experience
5
MINDFULNESS, ANXIETY, AND PSYCHOSIS
psychosis. Prevention mechanisms like mindfulness may be used to help the individual increase
their well-being and reaction to stress, so resilience to stressful situations can reduce an
individual likelihood of experiencing psychosis and becoming hospitalized.
The inclusion of the mind and the body into therapeutic treatment is thought to help
reduce distress. With reduction of distress, people with psychosis may be able to have a higher
functioning life, in which they may be able to even work. Davis and colleagues, (2015) used
mindfulness training to see if individuals with schizophrenia will have better job performance.
Their Mindfulness Intervention for Rehabilitation and Recovery in Schizophrenia (MIRRORS)
program helped increase job performance and job attendance than an intensive support group.
Although, this study used mindfulness in an outpatient setting with participants in stable phase of
schizophrenia it still shows that mindfulness is an effective therapy.
Laithwaite and associates (2009) use compassionate focused therapy in a high security
setting to promote help seeking and to develop compassion towards oneself. It used inpatient
facility to improve the well-being of participants by having them focus on themselves, similarly
to meditation. As Penn and colleagues (2004) have shown, schizophrenia and therapeutic
progress is increased with some type of therapy than with medication alone.
Therefore, mindfulness should be taken into great consideration when working with
populations experiencing psychosis. Kuyken and fellow researchers (2008) used mindfulness
based cognitive therapy (MBCT) to prevent relapse into hospitals. Although, their targeted
population was those with recurrent depression they still found that relapse in those with
medication and MBCT was less than those that just had anti-depressant and standard therapy
(Kuyken et al 2008).

MINDFULNESS, ANXIETY, AND PSYCHOSIS
In their 2005 study, Chadwick, Taylor and Abba, used mindfulness training to see if
individuals with psychosis could better deal with their psychotic episodes and understand what it
means to be mindful. Although, it was a pilot study they found that the participants seem to have
greater awareness of their psychosis and through mindfulness were able to cope better and not be
distressed by their hallucinations. They were able to maintain their well-being and use their
awareness of their senses to recognize external stimuli from their internal stimuli.
Holistic approaches have been beneficial in continuing the connection between the mind
and body. Mindfulness focuses on this connection in greater detail than other holistic
approaches. Through mindfulness based training, greater awareness to psychosis and dealing
with internal stimuli has been found (Chadwick, Taylor, and Abba 2005). Although, many
studies have found a link between mindfulness and improvement of quality of life they have
neglected to include an environment that many who experience psychosis tend to get counseling
and treatment from, an inpatient facility. Therefore, purpose of this study is to evaluate whether
mindfulness training will reduce anxiety in individuals experiencing psychosis in an acute
inpatient facility.

Method
Participants
Thirty participants will be chosen from G. Werber Bryan Psychiatric Hospital (BPH)
from two separate acute in patient lodges; with fifteen participants on each lodge, respectively.
The participants anticipated age range would be from 18 years of age to 59 years of age with an
anticipated average of 32 years of age. The expected gender makeup of the participants would be
twenty-eight men and two women. The participants will be of different ethnicities, but mainly
African American and European American descent. The participants will be chosen based on the
following criteria: at least two weeks of stay at BPH prior to beginning of research with at least
two weeks of stay at BPH before discharge, and the diagnosis of schizophrenia, schizoaffective
disorder, or bipolar one with psychosis as defined by the DSM V. Participants that meet these
requirements will further be eliminated based on their level of cognitive functioning with the
mental status examination.
After selection. The fifteen participants on lodge 1 and lodge 2 will then be randomly
assigned to either Group A, the mindfulness training or Group B, the standard training of BPH.
Both of the groups will be conducted on the participants’ lodges so they did not have to meet
outside of their lodge. On lodge 1, eight participants will be assigned to Group A, while seven
participants will be assigned to Group B. On lodge 2, seven participants will be assigned to
Group A, while eight participants will be assigned to Group B. All participants are anticipated to
stay throughout the intended study time of two weeks.

The Mental Health Status Examination (MHSE) will be used to assess cognitive ability
and memory retention for participants to participate. The inter-rater validity is strong and the
external validity is shown through the wide use in mental health settings.
The State Trait Anxiety Inventory (STAI) will be used prior to first group meeting and
after the last group meeting. This tool is to assess how much the participants’ anxiety levels
decrease. It has validity in the range of 0.69 to 0.89 with test-retest (APA 2016).
The Beck’s Anxiety Inventory (BAI) will be used prior to the first group meeting and
after the last group meeting to make sure that the mindfulness addresses physical attributes of
anxiety. It is a 21-item self-report inventory with a high internal consistency (alpha=0.92) and a
high test-retest reliability of 0.75 over one-week period (Beck, Epstein, Brown, and Steer 1988).
The Cognitive and Affective Mindfulness Scale-Revised (CAMS-R) is a 12-item self-
report inventory that will be used to see if participants understand mindfulness. It has an
acceptable internal consistency and will only be given to only participants in Group A during the
first group and after the last group has been administered. [Feldman, Hayes, Kumar, Greeson,
and Laureanceau 2007]
Design
This study will be a between-subjects, experimental design. The independent variables
are the two following groups: mindfulness training and standard BPH training. The dependent
variable is the amount of anxiety reduction experienced by the participants. By having two
groups a day one in the morning and one in the afternoon, it will help control for participants that
may not be “morning” people.

Procedures
After getting permission from Bryan G. Werber Psyhiatric Hospital Institutional Review
Board and South Carolina Department of Mental Health Institutional Review Board,
respectively, participants will be chosen with help of treatment team members on each acute
lodge. The patients will then be asked to participate in the study with the knowledge of getting a
credit at the canteen for two items three days a week for the two-week time period the groups are
administered. The participants will be given the informed consent and will be given the option to
participate in the study.
After all consents are signed. The participants will be randomly assigned into either
mindfulness training group, Group A, or standard training group, Group B. The groups will meet
twice a day on Monday-Friday and once a day on Saturday, for a two-week time period.
Group A: Mindfulness Training
This group training was modeled from Chadwick, Hughes, Russell, Russell, and Dagnan
(2009), mindfulness groups and will be conducted by the author of this paper. The groups will
meet twice a day: in the morning, focus will be on the body and the sensations that are a part of
it; and in the afternoon, focus will be on the participants’ psychosis and how to change their
reaction to their internal stimuli. Each group will be 45 minutes in length, with 15 minutes
dedicated to reflection of the content of group. At least one time a week, if weather permits the
groups will be held outside. Homework to continue body scans and observations of senses will
be given to the participants at the end of both groups.
Group B: Standard Training
10
MINDFULNESS, ANXIETY, AND PSYCHOSIS
Like Group A, this group will meet twice a day and will continue to focus on the rational
behavior therapy that BPH teaches. This group will continue to be taught by the same clinical
counselor who has facilitated groups there prior to start of this study to maintain consistency
between both lodges.
11
MINDFULNESS, ANXIETY, AND PSYCHOSIS
Expected Results
Based on prior research, I expect to see some improvement in anxiety as it relates to
psychosis in the individuals that are in Group A. I expect to use a two-way ANOVA analysis in
excel to compare the before and after of STAI with both groups. I will also use ANOVA to
compare before and after BAI results. I also expect to use a t-test to compare CAMS-R from
before and after mindfulness groups are administered. I expect to see a larger decrease in anxiety
with individuals in Group A than in individuals in Group B. I also expect to see an increase in
mindfulness after the groups have been administered than before in participants of Group A. I
expect to see a very small p-value (0.05 or smaller) to support that training in mindfulness does
reduce anxiety in participants in that population so my null hypothesis of no change between
groups in reduction anxiety can be rejected with confidence. I also expect to see that the t-value
for my t-test will be 0.05 or smaller to show significance difference of knowledge of
mindfulness.

MINDFULNESS, ANXIETY, AND PSYCHOSIS
Discussion
Although, this study has not been actively conducted, it is believed it will serve as a great
contribution to the hospital setting. Many patients experiencing psychosis, do not get a holistic
approach to their treatment. The symptoms are treated, but the mind and body are not allowed to
be connected together for better health and well-being in patients. If anxiety is reduced when this
study is actually conducted, another factor that can be added to better enhance future studies is
the amount of time for relapse. If relapse back into the hospital is reduced due to patients’ ability
to use mindfulness training outside of inpatient facilities, it would be a better investment and
could lead to lower costs for insurance companies in the long run. It will also be crucial to try
and include more women and diversity into these future inpatient facilities study. This study can
also be changed for the purpose of not including psychosis and looking into mindfulness training
for other patients who are in psychiatric inpatient facilities.

• Taken as a whole, it appears that exposing
these myths as myths increases the
acceptance of the mentally ill and that staged
contact with a mentally person to expose
myths has an even more powerful effect.
Caution must be advised, though; Martin et
al.’s (2002) and Alexander and Link’s (2003)
studies and the first study of Corrigan et al.
(2002) were based upon paper and pencil
methodologies. And while Corrigan et al.’s

in a college setting with a college sample.

The Social Phobia Scale was utilized in this study
(see Appendix). It is a questionnaire consisting of 15
items in which the subject is asked to put a
checkmark in the blank in front of any item that is
applied to them in the last six months. It was created
as an assignment in Psychological Statistics and
Measurements class at South University. Internal
reliability is been determined for the scale, and
content and construct validity have been established
as well.

A website was created for presenting various
surveys (see appendix). The Keirsey
Temperament Sorter (Keirsey, 1998b) and the
Keirsey Character Sorter (Keirsey, 1998c) were
utilized to measure personality type. Two other
surveys developed by the researcher were also
administered: a short demographic survey (see
Appendix) and an assessment of the degree of
domestic violence experienced by each
participant (see appendix). All the surveys were
conducted on the computer with the results
recorded on an answer sheet (see appendix).

Introduction
: Repeat violent injury is common among young urban men and is increasingly a focus
of trauma center–based injury prevention efforts. Though understanding risk factors for repeat
violent injury may be critical in designing such interventions, this knowledge is limited. This study
aims to determine which criminal behaviors, both before and after the initial trauma, predict repeat
violent trauma. Gun, violent, and drug crimes are expected to increase risk of subsequent violent
injury among victims of violence.
Methods: A case–control design examined trauma registry and publicly available criminal data for
all male patients aged o40 years presenting for violent trauma between April 2006 and December
2011 (N¼1,142) to the sole Level 1 trauma center in a city with high rates of violence. Logistic
regression was used to determine criminal behaviors predictive of repeat violent injury. Data were
obtained and analyzed between January 2013 and June 2014.
Results: Regarding crimes committed before the first injury, only drug crime (OR¼5.32) predicted
repeat violent trauma. With respect to crimes committed after the initial injury, illegal gun
possession (OR¼2.70) predicted repeat victimization. Initiating gun (OR¼3.53) or drug crime
(OR¼5.12) was associated with increased risk.
Conclusions: Prior drug involvement may identify young male victims of violence as at high risk of
repeat violent injury. Gun carrying and initiating drug involvement after the initial injury may
increase risk of repeat injury and may be important targets for interventions aimed at preventing
repeat violent trauma.

victims of violence, repeat injury is common,5–9 and
trauma center–based interventions to reduce repeat
violent trauma have recently emerged.10–15 Such inter-
ventions have yielded only mixed results, possibly
because most interventions focus on enrolling patients
in general outpatient case management services rather
than changing specific risk behaviors.16 Interventions
targeted at specific behaviors known to increase risk of
later violence/violence injury may have greater chances
of success.17
Certain criminal behaviors—specifically violent, gun,
and drug offenses—may be strong candidate risk factors
for repeat violent trauma.2,5,7 Violent behavior invites
violent retaliation. Assaults are more likely to involve
more-severe gunshot injuries if assailants expect the
target to be similarly armed.18 Violence also permeates
illicit drug economies, as disputes cannot be settled

legally.19 Other forms of crime, like unarmed, non-
confrontational property crime (e.g., auto theft) may be
less likely to provoke retaliatory violence and may be less
associated with repeat injury risk. Empirical studies
focused on crime and trauma recidivism are generally
consistent with this pattern, but methodologic limita-
tions preclude definitive conclusions. One study5 found
that violent, gun, and drug crimes were more common
among repeat victims of violence than among patients
injured accidentally. This study, however, did not com-
pare repeat to single episode victims of violence and it
relied exclusively on survey methods to assess criminal-
ity. A second study7 found that gun, drug, and violent
crime, but not property crime or crime in general, were
more common among repeat than single-episode trauma
patients. Nonetheless, this study7 combined violent and
accidental trauma patients, so it is not clear if these
findings hold for those who specifically experience
violent trauma.
Extant literature also has not differentiated between
crimes committed before and those committed after first
injury. This issue is important for the development of
trauma center–based interventions. Understanding
which behaviors occurring prior to the first trauma are
associated with rehospitalization is useful in identifying
those initial trauma victims most at risk of future violent
trauma. However, this information may be less relevant
for intervention development because these historic
risk factors may be static or unchangeable through
intervention. By contrast, understanding the risk behav-
iors that occur after the initial hospitalization is critical
for development of hospital-based interventions,17 as
these are the behaviors such interventions can influence
most directly. For example, the experience of trauma
may lead to new risk behaviors (e.g., regular gun
carrying or drug involvement).2,20,21 Whether such
changes increase risk of repeat trauma, making them
potential targets for intervention, has not been examined
directly.
The present case–control study aims to identify differ-
ences in criminal behavior between repeat and single-
episode victims of violence. To address limitations of
previous studies, administrative hospital and criminal
data are examined, and criminal behaviors occurring
prior to the initial trauma are coded separately from
those occurring after first injury. It is hypothesized that
violent crime, gun possession, gun use, and drug crime,
both prior to and following initial trauma, would predict
repeat violent trauma, but that property crime, both
before and after, would not. Finally, as a stronger
demonstration that risk behaviors may be useful targets
of intervention, it is examined whether those who do not
engage in specific criminal behaviors prior to the first
trauma but begin engaging in that crime afterwards have
higher chances of repeat violent injury than those who
continue to abstain. It is expected that initiating gun
possession, gun use, and violent or drug crime following
a violent trauma would increase risk of repeat violent
injury, but that initiating property crime would not.
Methods
Study Population
The study was approved and a waiver of informed consent was
granted by the IRB of the Louisiana State University Health
Sciences Center, New Orleans. A study population consisting of
all adult male patients aged r40 years from Orleans Parish who
were admitted to the Spirit of Charity Level 1 Trauma Center
(SOCTC) with a violent injury between April 2006 and December
2011 and who survived their initial injury was identified from the
trauma center trauma registry (N=1,243). The SOCTC is the only
Level 1 trauma center in New Orleans and thus treats all severe
violent injuries (e.g., gunshot wounds) that occur in the metro-
politan area. From Hurricane Katrina in August 2005 until the
Trauma Center’s reopening in April 2006, there is an 8-month gap
in the trauma registry. For this reason, only data after April 2006
were examined.
Violent trauma was operationalized as hospital presentations
with an ICD-9 e-code of 960–969, specifically indicating inten-
tional violent injury. Cases of violent trauma recidivism were
identified by linking trauma center presentations according to
patient name, Social Security Number (SSN), and birth date.
Patients who presented with a violent trauma between April 2006
and December 2011 and then presented with at least one
additional violent trauma between April 2006 and December
2012 were classified as violent trauma repeaters (n=93). The
control group consisted of patients who presented to the trauma
center with a violent trauma between April 2006 and December
2011 but no additional violent traumas from April 2006 to
December 2012 (n=1,150). All databases with patient identifiers
were destroyed following the linking of hospital and criminal
databases.
Data Sources
The trauma registry contains demographic, medical, and patient
outcome data on patients for whom the hospital trauma activation
protocol is initiated. Demographic data included date of injury;
name; birth date; SSN; gender; race (self-report or if necessary as
determined by medical staff); age; and ZIP code of residence.
Cause of injury data included the ICD-9 e-code identifying the
mechanism (e.g., gun or knife) and apparent intent (i.e., inten-
tional versus accidental) of injuries. Criminal data were retrieved
from the Orleans Parish Criminal District Court docket master.
Patients were linked to criminal records by their name and date of
birth. Dates and nature of all criminal convictions were recorded.
Criminal behavior was classified according to five categories: gun
possession, gun use, drug crime, violent crime, and property crime.
Gun possession crimes were defined as convictions that only
involved the illegal possession or use of a firearm, without any use
or threat of use against another person. Gun use crimes required

Nanney et al / Am J Prev Med 2015;49(3):395–401 397
firearm use or threat of use against others. Violent crimes were
defined as all those involving interpersonal aggression or violence.
Drug crimes were defined as those that included the possession or
distribution of illicit substances. Property crimes were defined as
those that require the unlawful entry or unlawful taking, pos-
session, or destruction of another person’s property.
Criminal behavior categories, with the exception of gun
possession, were not mutually exclusive, so each criminal act
could count toward multiple categories (e.g., shooting a person
would count as a violent crime and a gun use crime). To better
isolate the impact of mere gun possession, gun possession and gun
use were coded to be mutually exclusive. That is, if an individual
used a gun in a crime at any point during a given time period (i.e.,
before or after initial injury) they could not be coded positive for
gun possession during that time period. Separate variables were
created for crimes committed before and crimes committed after
the initial injury. For those with multiple violent injuries, crime
after the first trauma included only those crimes that occurred
before the last violent injury in order to focus only on crimes that
could logically contribute to repeat trauma risk. Trained research
assistants conducted the crime ratings. Inter-rater reliability was
assessed by having independent raters separately code criminal
history for 20% of patients. Inter-rater reliability was excellent
(κ=0.90).
Statistical Analysis
Data were analyzed in April–June 2014 using SPSS, version 21.0. A
multivariate logistic regression model was used to examine the
independent contribution of crimes in predicting repeat trauma.
Criminal behaviors occurring prior to the initial injury were
entered at Step 1. Criminal behaviors occurring after the initial
trauma were then entered at Step 2.
To examine how behavior change following initial trauma may
impact repeat injury risk, patients who did not engage in a given

form of crime prior to the initial trauma were coded dichoto-
mously as to whether they either (1) continued to abstain from that
type of crime or (2) began engaging in that type of crime. For each
type of crime, a separate logistic regression was conducted with
repeat victimization as the dependent variable and this crime
initiation variable as the independent variable. History of other
types of crime was controlled.
A potential study confounder is time following initial injury in
which crime can be observed. For those without re-injury, there
was no repeat injury to signal end of observation, which then
continued until the end of the study (December 2012). The
observation period was thus considerably longer among those
without later injury compared with repeat victims (F=135.39,
po0.001), potentially biasing results. Observation time after the
first injury was thus controlled in all analyses. Race was controlled
in all analyses because African Americans may be disproportion-
ately likely to receive certain criminal convictions22 and be
assaulted with a weapon.18
Results
Demographics and injury characteristics appear in
Table 1. Repeat victims of violent trauma (n¼93)
comprised 7.5% of the overall sample (N¼1,243). Repeat
violent trauma victims were significantly younger than
those with only a single violent injury and were more
likely to have initially presented with a gunshot injury
than single-episode victims. Though African Americans
predominated in the overall population of violently
injured young men (82.8%), repeat victims of trauma
were almost exclusively black. Rates of criminal con-
viction, both before and after the first injury, are included

crimes the least common, both before and after initial

Results of the multivariate logistic regression (Table 3)
indicate that when considering only crimes prior to the
initial trauma (Step 1), only pre-injury drug crime
significantly predicted repeat trauma (p¼0.01). When

significantly predicted repeat violent trauma (p¼0.03)

Discussion
Gun and drug crimes, as expected, predict repeat violent
trauma. The relationship of these criminal behaviors to
repeat trauma appears to be more complex than pre-
viously recognized, however. At the time of the initial
injury, only a history of drug crime predicts repeat
victimization. This risk continues even when controlling
for subsequent criminal behavior. Once one becomes
involved and identified with the illicit drug market, it may
be difficult to extricate oneself from the violent social
milieu and intergroup conflict that surround it.19 Initia-
tion of drug crime following first injury is associated with
increased risk. Victims of trauma may turn to substances
in order to self-medicate,2,23 increasing their vulnerability
due to exposure to this violent market. Surprisingly,
overall drug crime following first trauma is only margin-
ally significant. Perhaps, for those already involved in the
drug market, additional drug crime confers only small
incremental risk. History of gun crime at first injury is not
associated with increased risk. Only after initial injury
does gun crime emerge as a predictor of later victim-
ization, and this is only for gun possession, not gun use.
For the emblematic patient at highest risk for repeat
violent trauma, an initial injury may enhance recognition
of the violence associated with the illicit drug market
leading to an increase in weapon carrying as a means of
protection.2,20,21 The present results underscore the grave
risks that may be associated with this, as it appears that
initiating gun possession following the initial injury is an
important determinant of an individual’s risk for repeat
violent injury. It is unclear why weapon carrying is a risk
factor after, but not before, the initial injury. Perhaps after
an initial injury, individuals may display weapons more
openly to deter possible assailants. Being known to carry a
weapon increases the likelihood that, when conflict does
occur, the other party will arm themselves similarly,

leading to higher chances of severe injury.18 Surprisingly,
the actual use of a gun in a crime and violence more
generally do not predict repeat violent injury. Such crimes
carry higher chances of lengthy prison terms, such that
some individuals engaging in them may be protected
from repeat violent trauma because of their incarceration.
Some convicted of gun possession may also have been
preparing to use the weapon absent legal intervention.
Finally, it is noteworthy that African American race is
associated with repeat injury even controlling for other
factors. Although it is possible that SES could in part
explain this relationship, this finding is consistent with
literature suggesting that a bias in perceiving African
American men as dangerous makes them more likely to
be targets of more severe, armed assaults when conflicts
emerge.18
Differentiating between risk behaviors that occur
before and those that occur after the initial trauma allows
us to provide more nuanced clinical guidance than prior
research. A history of drug crime at first injury marks
violent trauma patients as higher risk for violent re-
injury. Trauma centers may thus benefit from routinely
screening for drug involvement and targeting interven-
tions to this higher-risk group. Primary substance abuse
prevention models24 may help reduce repeat violence by
preventing involvement in the violent drug market in the
first place. The methods used in the present study allow
us to conclude with greater confidence that certain
behaviors occurring after the initial injury, particularly
gun carrying and drug involvement, may be appropriate
targets for trauma center–based interventions. Fortu-
nately, such interventions for both are developing. A
trauma center–based intervention directly targeting gun-
carrying adolescents was recently found to reduce
chances of continued firearm carrying at 1 year of
follow-up.25 Though replications with adults are
required, this finding—in combination with the present
findings—suggests that direct behavioral intervention
regarding gun carrying may have the potential to reduce
repeat violent trauma. Such interventions likely should
September 2015
not be limited to those who already have a history of
carrying guns. Indeed, many of those at risk may not yet
have begun engaging in significant gun carrying at the
time of the injury.2,20,21 Clinicians may anticipate that
patients without histories of gun use may be considering
arming themselves in the wake of their trauma. Develop-
ment of preventive interventions that directly inquire
about plans for gun use after the injury and attempt to
guide this decision-making process may be needed. With
respect to drug involvement, general substance abuse
prevention strategies are widely available20,26 and trauma
center–based interventions for illicit drug use are
developing.27
Limitations
Criminal data include only illegal behaviors that warrant
criminal prosecution and conviction. Such data cannot
determine if purely legal gun possession confers risk of
violent injury, though a relationship between legal gun
possession and violent injury has been suggested.28–31
Results also may not extend to less severe illegal
behaviors that do not lead to arrest, prosecution, and
conviction (e.g., occasional recreational drug use).
Whether risk of repeat injury from drug crime is a
function of drug use or drug distribution cannot be
determined given that both often may yield similar
convictions for drug possession.32 The trauma registry
contains only the most critical injuries that require
treatment at a Level I trauma center. Results thus may
not extend to the majority of violent injuries that do not
require this level of care.
Our study is limited to a single metropolitan area, New
Orleans, at a unique period in its history (i.e., the
aftermath of Hurricane Katrina). Owing to the high rates
of migration during this period, some participants in this
study may have been injured or may have engaged in
crime in another location. Even participants who resided
in New Orleans throughout the duration of the study
may have been injured or committed crimes while
outside of the area. Additional research using a broader
Nanney et al / Am J Prev Med 2015;49(3):395–401400
geographic region would thus be needed to confirm the
present findings. Also, given the gap in trauma registry
data owing to Hurricane Katrina, this study is com-
pressed into a relatively narrow time frame. The time
between first and second injury in our study suggests that
about 90% of patients who will return with repeat violent
injuries from the 2006–2011 population are captured in
these data, but that about 10% of the repeat victims of
violence in this population are likely “incorrectly”
classified as single-episode victims of violence because
they have not yet returned with their second violent
injury. Likewise, it is possible that an unknown number
of patients experienced violent injuries prior to the
beginning of the study data in 2006 such that they too
are incorrectly classified as single-episode victims. Anal-
ysis of a narrower cohort (2006–2008) for which 99% of
repeat trauma victims are likely captured produced
results substantively similar to the larger population,
increasing the confidence that the present findings would
persist if the database were extended in both the past and
future.
Conclusions
Though repeat violent injury is a public health priority
for young urban men and increasingly a focus of
intervention, research examining risk factors for
repeat trauma remains sparse. The present results
confirm previous scholarship suggesting that gun and
drug crimes predict repeat violent injury. Analysis of
timing of these crimes in relation to the initial injury
indicates that drug crime before and gun possession
after predict repeat trauma. Initiating gun or drug
crime after injury also predicts later violent injury.
Trauma center–based interventions targeting gun
carrying and drug involvement may thus have prom-
ise in reducing the violence that continues to plague
many urban neighborhoods.
