Trajectory of adjustment difficulties following disaster: 10-year longitudinal cohort study. BJPsych Open 2024; 10:e57. [PMID: 38433588 PMCID: PMC10951843 DOI: 10.1192/bjo.2024.3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/14/2023] [Revised: 10/19/2023] [Accepted: 01/02/2024] [Indexed: 03/05/2024] Open
Abstract
BACKGROUND Although much is known about psychopathology such as post-traumatic stress disorder (PTSD) and depression following bushfire (also known as wildfire), little is known about prevalence, trajectory and impacts for those experiencing general adjustment difficulties following exposure to these now-common events. AIMS This was an exploratory analysis of a large cohort study that examined the prevalence, trajectory and risk factors of probable adjustment disorder over a 10-year period following bushfire exposure. METHOD The Beyond Bushfires study assessed individuals exposed to a large and deadly bushfire across three time points spanning 10 years. Self-report survey data from participants from areas with moderate and high levels of fire-affectedness were analysed: n = 802 participants at Wave 1 (3-4 years post-fires), n = 596 at Wave 2 (5 years post-fires) and n = 436 at Wave 3 (10 years post-fires). Surveys indexed fire-related experiences and post-fire stressors, and comprised the six-item Kessler Psychological Distress Scale (probable adjustment disorder index), four-item Posttraumatic Stress Disorder Checklist (probable fire-related PTSD) and nine-item Patient Health Questionnaire (probable major depressive episode). RESULTS Prevalence of probable adjustment disorder was 16% (Wave 1), 15% (Wave 2) and 19% (Wave 3). Probable adjustment disorder at 3-4 years post-fires predicted a five-fold increase in risk for escalating to severe psychiatric disorder (i.e. probable fire-related PTSD/major depressive episode) at 10 years post-fires, and was associated with post-fire income and relationship stressors. CONCLUSIONS Adjustment difficulties are prevalent post-disaster, many of which are maintained and exacerbated over time, resulting in increased risk for later disorder and adaptation difficulties. Psychosocial interventions supporting survivors with adjustment difficulties may prevent progression to more severe disorder.

Abstract
Alexithymia is the inability to identify and recognize emotions. The present study examined the impact of alexithymia on prolonged exposure (PE) therapy. Participants (n = 68) with PTSD underwent 10 PE sessions. Alexithymia was assessed via the Toronto Alexithymia Scale (TAS-20) and the emotional clarity and awareness subscales of the Difficulties in Emotion Regulation Scale. Treatment outcomes were assessed via the PTSD checklist and Clinician-Administered PTSD Scale for the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition at posttreatment and 6-month follow-up. Those with high alexithymia were more likely to endorse experiencing a full PTSD diagnosis immediately posttreatment, χ²(1) = 12.53, p = .002, and at 6-month follow-up, χ²(1) = 11.21, p = .004. Alexithymia was associated with delayed treatment effects on avoidance, with a significant reduction in symptomology observed from pre- to follow-up, t(51) = 4.52, p < .001, and not from pre- to posttreatment. Although both the low and high alexithymia groups showed significant changes in negative changes in thinking and mood, F(2, 14) = 9.18, p = .001, d = 1.57 and F(2, 50) = 13.86, p = .001, d = 1.49, respectively, the high alexithymia group exhibited a marginally lesser magnitude of treatment effect. Although those with significantly greater difficulties with emotional clarity were more likely to drop out of PE treatment, emotional clarity and awareness did not moderate treatment response. Our results confirm the efficacy of PE but also highlight that those with alexithymia show a delayed treatment response and may be at greater risk of pathology after treatment.

Abstract
Problem anger is a common, and potentially destructive mental health issue in trauma-affected populations, affecting up to 30% of veteran and military populations. Problem anger is associated with a range of psychosocial and functional difficulties and elevated risk of harm to self and others. Increasingly, ecological momentary assessment (EMA) is being used to understand the microlevel dynamics of emotions, and this information is valuable to inform treatment approaches. Using a data-driven approach, we used sequence analysis to determine whether heterogeneity exists amongst veterans with problem anger using EMA-recorded experiences of anger intensity. Veterans with problem anger (N = 60; Mage = 40.28) completed 10 days of EMA with four prompts per day. We identified four subtypes of veterans within the data, whose anger intensity dynamics differed significantly, and the subtypes mapped onto macrolevel indicators of anger and well-being. Taken together, these results highlight the importance of microlevel investigations of mood states in clinical populations, and in some instances, the novel use of sequence analysis may be appropriate.

Abstract
ABSTRACT There is a demonstrated association between alexithymia and posttraumatic stress disorder (PTSD). However, work has largely focused on male-dominant, high-risk occupation populations. We aimed to explore the relationship between posttraumatic stress (PTS) and alexithymia among 100 trauma-exposed female university students. Participants completed a Life Events Checklist, the PTSD Checklist for the Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition) (PCL-5), and the Toronto Alexithymia Scale (TAS-20). Multiple regressions were run to examine whether alexithymia was associated with each of the PCL-5 subscales. The TAS-20 total scores were associated with total PTS scores, β = 0.47, t(99) = 5.22, p < 0.001. On a subscale level, Difficulty in Identifying Feelings (DIF) was positively associated (β = 0.50 to 0.41) with all PCL-5 subscales except for Avoidance. Our results align with research showing that for women, the DIF subscale is most strongly associated with PTS, in contrast with the literature on male samples, showing strongest associations with the Difficulties in Describing Feelings subscale, suggesting sex differences in associations between PTS and alexithymia. Our study supports the universality of the associations between alexithymia and PTS.

Emotion response disconcordance among trauma-exposed adults: the impact of alexithymia. Psychol Med 2023; 53:5442-5448. [PMID: 35975360 PMCID: PMC10482720 DOI: 10.1017/s0033291722002586] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/26/2021] [Revised: 05/28/2022] [Accepted: 07/22/2022] [Indexed: 11/07/2022]
Abstract
BACKGROUND Emotion processing deficits have been identified as a critical transdiagnostic factor that facilitates distress after trauma exposure. Limited skills in identifying and labelling emotional states (i.e. alexithymia) may present on the more automated (less conscious) end of the spectrum of emotional awareness and clarity. Individuals with alexithymia tend to exhibit a disconcordance between subjective experience and autonomic activity (e.g. where high levels of subjective emotional intensity are associated with low physiological arousal), which may exacerbate distress. Although there is a robust link between alexithymia and trauma exposure, no work to date has explored whether alexithymia is associated with emotional response disconcordance among trauma-exposed adults. METHOD Using a validated trauma script paradigm, the present study explored the impact of alexithymia on emotion response concordance [skin conductance (Galvanic Skin Response, GSR) and Total Mood Disturbance (TMD)] among 74 trauma-exposed adults recruited via a posttraumatic stress disorder (PTSD) treatment clinic and student research programme. RESULTS Unlike posttraumatic symptom severity, age, sex, participant type and mood (which showed no effect on emotion response concordance), alexithymia was associated with heightened emotion response disconcordance between GSR and TMD [F(1, 37) = 8.93, p = 0.006], with low GSR being associated with high TMD. Observed effects of the trauma script were entirely accounted for by the interaction with alexithymia, such that those with alexithymia showed a negligible association between subjective and physiological states. CONCLUSION This finding is paramount as it shows that a large proportion of trauma-exposed adults have a divergent emotion engagement profile.

Abstract
This study investigated whether impairment persists after posttraumatic stress disorder (PTSD) has resolved. Traumatically injured patients (N = 1,035) were assessed during hospital admission and at 3 (85%) and 12 months (73%). Quality of life prior to traumatic injury was measured with the World Health Organization Quality of Life-BREF during hospitalization and at each subsequent assessment. PTSD was assessed using the Clinician-Administered PTSD Scale at 3 and 12 months. After controlling for preinjury functioning, current pain, and comorbid depression, patients whose PTSD symptoms had resolved by 12 months were more likely to have poorer quality of life in psychological (OR = 3.51), physical (OR = 10.17), social (OR = 4.54), and environmental (OR = 8.83) domains than those who never developed PTSD. These data provide initial evidence that PTSD can result in lingering effects on functional capacity even after remission of symptoms.

Abstract
The seven-item Hospital Anxiety and Depression Scale Depression subscale (HADS-D) and the total score of the 14-item HADS (HADS-T) are both used for major depression screening. Compared to the HADS-D, the HADS-T includes anxiety items and requires more time to complete. We compared the screening accuracy of the HADS-D and HADS-T for major depression detection. We conducted an individual participant data meta-analysis and fit bivariate random effects models to assess diagnostic accuracy among participants with both HADS-D and HADS-T scores. We identified optimal cutoffs, estimated sensitivity and specificity with 95% confidence intervals, and compared screening accuracy across paired cutoffs via two-stage and individual-level models. We used a 0.05 equivalence margin to assess equivalency in sensitivity and specificity. 20,700 participants (2,285 major depression cases) from 98 studies were included. Cutoffs of ≥7 for the HADS-D (sensitivity 0.79 [0.75, 0.83], specificity 0.78 [0.75, 0.80]) and ≥15 for the HADS-T (sensitivity 0.79 [0.76, 0.82], specificity 0.81 [0.78, 0.83]) minimized the distance to the top-left corner of the receiver operating characteristic curve. Across all sets of paired cutoffs evaluated, differences of sensitivity between HADS-T and HADS-D ranged from -0.05 to 0.01 (0.00 at paired optimal cutoffs), and differences of specificity were within 0.03 for all cutoffs (0.02-0.03). The pattern was similar among outpatients, although the HADS-T was slightly (not nonequivalently) more specific among inpatients. The accuracy of HADS-T was equivalent to the HADS-D for detecting major depression. In most settings, the shorter HADS-D would be preferred.

Abstract
Transitioning out of the military can be a time of change and challenge. Research indicates that altered threat monitoring in military populations may contribute to the development of psychopathology in veterans, and interventions that adjust threat monitoring in personnel leaving the military may be beneficial. Australian Defence Force personnel (N = 59) transitioning from the military were randomized to receive four weekly sessions of either attention-control training or a placebo attention training. The primary outcome was symptoms of posttraumatic stress disorder (PTSD), as measured using the PTSD Checklist for DSM-5 (PCL-5) at posttreatment. Following training, participants who received attention-control training reported significantly lower levels of PTSD symptoms, Hedges' g = 0.86, 95% CI [0.37, 1.36], p = .004, and significantly improved work and social functioning, Hedges' g = 0.93, 95% CI [0.46, 1.39], p = .001, relative to those in the placebo condition. Moreover, no participants who received attention-control training worsened with regard to PTSD symptoms, whereas 23.8% of those who received the placebo attention training experienced an increase in PTSD symptoms. The preliminary findings from this pilot study add to a small body of evidence supporting attention-control training as a viable indicated early intervention approach for PTSD that is worthy of further research.

Problem anger in veterans and military personnel: Prevalence, predictors, and associated harms of suicide and violence. J Psychiatr Res 2022; 151:57-64. [PMID: 35453092 DOI: 10.1016/j.jpsychires.2022.04.004] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/19/2021] [Revised: 03/06/2022] [Accepted: 04/04/2022] [Indexed: 01/18/2023]
Abstract
BACKGROUND Problem anger is increasingly identified as an important issue, and may be associated with suicidality and violence. This study investigates the relationship between problem anger, suicidality, and violence amongst veterans and military personnel. METHODS Cross-sectional survey data from n = 12,806 military personnel and veterans were subject to analyses. These considered the weighted prevalence of problem anger, while further analyses of veterans (n = 4326) considered risk factors and co-occurrence with other psychiatric conditions. Path analyses examined inter-relationships involving anger, violence and suicidality. RESULTS There were 30.7% of veterans and 16.4% of military personnel that reported past month problem anger, while 14.9% of veterans and 7.4% of military personnel reported physical violence. There were higher levels of suicidality among veterans (30.3%), than military personnel (14.3%). Logistic regression models indicated that PTSD was the strongest risk factor for problem anger (PCL-5, OR = 21.68), while there were small but substantial increases in anger rates associated with depression (OR = 15.62) and alcohol dependence (OR = 6.55). Path models indicated that problem anger had an influence on suicide attempts, occurring primarily through suicidal ideation, and an influence on violence. Influences of problem anger on suicidal ideation and violence remained significant when controlling for co-occurring mental health problems. CONCLUSIONS Problem anger, violence, and suicidality are common and inter-related issues among military personnel and veterans. Problem anger is a unique correlate of suicidality, supporting the need for anger to be included as part of violence and suicide risk assessment, and clinician training.

A predictive coding account of value-based learning in PTSD: Implications for precision treatments. Neurosci Biobehav Rev 2022; 138:104704.

Abstract
While there are a number of recommended first-line interventions for posttraumatic stress disorder (PTSD), treatment efficacy has been less than ideal. Generally, PTSD treatment models explain symptom manifestation via associative learning, treating the individual as a passive organism - acted upon - rather than self as agent. At their core, predictive coding (PC) models introduce the fundamental role of self-conceptualisation and hierarchical processing of one's sensory context in safety learning. This theoretical article outlines how predictive coding models of emotion offer a parsimonious framework to explain PTSD treatment response within a value-based decision-making framework. Our model integrates the predictive coding elements of the perceived: self, world and self-in the world and how they impact upon one or more discrete stages of value-based decision-making: (1) mental representation; (2) emotional valuation; (3) action selection and (4) outcome valuation. We discuss treatment and research implications stemming from our hypotheses.

Abstract
OBJECTIVE Anger is a salient feature of posttraumatic mental health which is linked to posttraumatic stress disorder (PTSD) and may have implications for treatment. However, the nature of associations involving anger and PTSD remains unclear. The aim of the present study was to examine bidirectional influences involving anger and International Classification of Diseases (ICD)-11 PTSD symptom clusters over time among treatment-seeking veterans. METHOD Current or ex-serving members (n = 742; 92.4% male) who participated in an accredited outpatient PTSD treatment program were administered measures of PTSD symptoms (PTSD checklist for Diagnostic and Statistical Manual of Mental Disorders, 5th edition [PCL-5]) and anger (Dimensions of Anger Reactions Scale-5 [DAR-5]) at treatment intake, discharge, and three-month follow-up. Bidirectional influences were assessed using cross-lagged panel analyses. RESULTS The majority of participants (78%) exhibited significant anger problems at intake. Cross-lagged analyses showed anger was associated with relative increases in PTSD symptoms of intrusive reexperiencing and avoidance at posttreatment, whereas no reverse effects of any PTSD symptoms on anger were observed. Anger continued to influence changes in heightened sense of threat and avoidance symptoms at three-months posttreatment. CONCLUSIONS Anger influences change in specific PTSD symptoms over time among military veterans in treatment and may interfere with treatments for PTSD. Veterans who present to clinical services with anger problems may benefit from anger interventions prior to commencing trauma-focused treatment. The findings have additional implications for conceptual models of the relationship between anger and PTSD. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

A Pilot Study of the Efficacy of the Unified Protocol for Transdiagnostic Treatment of Emotional Disorders in Treating Posttraumatic Psychopathology: A Randomized Controlled Trial. J Trauma Stress 2021; 34:563-574.

Abstract
The Unified Protocol for Transdiagnostic Treatment of Emotional Disorders (UP) is an intervention that targets common mechanisms that maintain symptoms across multiple disorders. The UP has been shown to be effective across many disorders, including generalized anxiety disorder, major depressive episode (MDE), and panic disorder, that commonly codevelop following trauma exposure. The present study represented the first randomized controlled trial of the UP in the treatment of trauma-related psychopathology, including posttraumatic stress disorder (PTSD), depression, and anxiety symptoms. Adults (N = 43) who developed posttraumatic psychopathology that included PTSD, MDE, or an anxiety disorder after sustaining a severe injury were randomly assigned to receive 10-14 weekly, 60-min sessions of UP (n = 22) or usual care (n = 21). The primary treatment outcome was PTSD symptom severity, with secondary outcomes of depression and anxiety symptom severity and loss of diagnosis for any trauma-related psychiatric disorder. Assessments were conducted at intake, posttreatment, and 6-month follow-up. Posttreatment, participants who received the UP showed significantly larger reductions in PTSD, Hedges' g = 1.27; anxiety, Hedges' g = 1.20; and depression symptom severity, Hedges' g = 1.40, compared to those receiving usual care. These treatment effects were maintained at 6-month follow-up for PTSD, anxiety, and depressive symptom severity. Statistically significant posttreatment loss of PTSD, MDE, and agoraphobia diagnoses was observed for participants who received the UP but not usual care. This study provides preliminary evidence that the UP may be an effective non-trauma-focused treatment for PTSD and other trauma-related psychopathology.

Rapid Design and Delivery of an Experience-Based Co-designed Mobile App to Support the Mental Health Needs of Health Care Workers Affected by the COVID-19 Pandemic: Impact Evaluation Protocol. JMIR Res Protoc 2021; 10:e26168. [PMID: 33635823 PMCID: PMC7945974 DOI: 10.2196/26168] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2020] [Revised: 01/10/2021] [Accepted: 02/25/2021] [Indexed: 01/19/2023] Open
Abstract
BACKGROUND The COVID-19 pandemic has highlighted the importance of health care workers' mental health and well-being for the successful function of the health care system. Few targeted digital tools exist to support the mental health of hospital-based health care workers, and none of them appear to have been led and co-designed by health care workers. OBJECTIVE RMHive is being led and developed by health care workers using experience-based co-design (EBCD) processes as a mobile app to support the mental health challenges posed by the COVID-19 pandemic to health care workers. We present a protocol for the impact evaluation for the rapid design and delivery of the RMHive mobile app. METHODS The impact evaluation will adopt a mixed methods design. Qualitative data from photo interviews undertaken with up to 30 health care workers and semistructured interviews conducted with up to 30 governance stakeholders will be integrated with qualitative and quantitative user analytics data and user-generated demographic and mental health data entered into the app. Analyses will address three evaluation questions related to engagement with the mobile app, implementation and integration of the app, and the impact of the app on individual mental health outcomes. The design and development will be described using the Mobile Health Evidence Reporting and Assessment guidelines. Implementation of the app will be evaluated using normalization process theory to analyze qualitative data from interviews combined with text and video analysis from the semistructured interviews. Mental health impacts will be assessed using the total score of the 4-item Patient Health Questionnaire (PHQ4) and subscale scores for the 2-item Patient Health Questionnaire for depression and the 2-item Generalized Anxiety Scale for anxiety. The PHQ4 will be completed at baseline and at 14 and 28 days. RESULTS The anticipated average use period of the app is 30 days. The rapid design will occur over four months using EBCD to collect qualitative data and develop app content. The impact evaluation will monitor outcome data for up to 12 weeks following hospital-wide release of the minimal viable product release. The study received funding and ethics approvals in June 2020. Outcome data is expected to be available in March 2021, and the impact evaluation is expected to be published mid-2021. CONCLUSIONS The impact evaluation will examine the rapid design, development, and implementation of the RMHive app and its impact on mental health outcomes for health care workers. Findings from the impact evaluation will provide guidance for the integration of EBCD in rapid design and implementation processes. The evaluation will also inform future development and rollout of the app to support the mental health needs of hospital-based health care workers more widely.

Abstract
Background: Despite growing support for the distinction between posttraumatic stress disorder (PTSD) and complex PTSD (CPTSD) as separate diagnoses within the ICD-11 psychiatric taxonomy, the prevalence and treatment implications of CPTSD among current and ex-serving military members have not been established. Objective: The study aims were to a) establish the prevalence of provisional ICD-11 CPTSD diagnosis relative to PTSD in an Australian sample of treatment-seeking current and ex-serving military members, and b) examine the implications of CPTSD diagnosis for intake profile and treatment response. Methods: The study analysed data collected routinely from Australian-accredited treatment programmes for military-related PTSD. Participants were 480 current and ex-serving military members in this programmes who received a provisional ICD-11 diagnosis of PTSD or CPTSD at intake using proxy measures. Measures of PTSD symptoms, disturbances in self-organisation, psychological distress, mental health and social relationships were considered at treatment intake, discharge, and 3-month follow-up. Results: Among participants with a provisional ICD-11 diagnosis, 78.2% were classified as having CPTSD, while 21.8% were classified as having PTSD. When compared to ICD-11 PTSD, participants with CPTSD reported greater symptom severity and psychological distress at intake, and lower scores on relationship and mental health dimensions of the quality of life measure. These relative differences persisted at each post-treatment assessment. Decreases in PTSD symptoms between intake and discharge were similar across PTSD (d RM = -0.81) and CPTSD (d RM = -0.76) groups, and there were no significant post-treatment differences between groups when controlling for initial scores. Conclusions: CPTSD is common among treatment-seeking current and ex-serving military members, and is associated with initially higher levels of psychiatric severity, which persist over time. Participants with CPTSD were equally responsive to PTSD treatment; however, the tendency for those with CPTSD to remain highly symptomatic post-treatment suggests additional treatment components should be considered.

Abstract
BACKGROUND Although trauma-focused cognitive behavioral therapy (TF-CBT) is the frontline treatment for posttraumatic stress disorder (PTSD), at least one-third of patients are treatment nonresponders. This study aimed to identify neural markers of treatment response, specifically the prediction of remission of specific PTSD symptoms. METHODS This study assessed PTSD treatment-seeking patients (n = 40) before TF-CBT during functional magnetic brain resonance imaging (fMRI) when they processed fearful, sad, happy, and neutral faces. Patients underwent nine sessions of TF-CBT and were independently assessed on the Clinician-Administered PTSD Scale (CAPS) following treatment. Treatment responders and nonresponders were compared with healthy controls (n = 40). The severity of PTSD was assessed with the CAPS. fMRI responses were calculated for each emotion face compared to neutral contrast, which were correlated with reduction in PTSD severity from pretreatment to posttreatment. Treatment response was categorized by at least 50% reduction in the severity of PTSD. RESULTS The activation of left insula during the processing of both sad and fearful faces was associated with a greater reduction of fear but not with dysphoric symptoms after treatment. Connectivity of the left insula to the pregenual anterior cingulate cortex was associated with poorer response to treatment. Responders and controllers had similar levels of activation and connectivity and were different from nonresponders. CONCLUSIONS Positive response to TF-CBT is predicted during emotion processing by normal levels of recruitment of neural networks implicated in emotional information. These findings suggest that distinct neural networks are predictive of PTSD fear and dysphoric symptom reduction following TF-CBT.

Abstract
The aim of this systematic review was to examine the efficacy of MDMA, ketamine, LSD, and psilocybin for the treatment of posttraumatic stress disorder (PTSD). A search of four databases for English language, peer-reviewed literature published from inception to 18th October 2019 yielded 2,959 records, 34 of which were screened on full-text. Observational studies and RCTs which tested the efficacy of MDMA, ketamine, LSD, or psilocybin for reducing PTSD symptoms in adults, and reported changes to PTSD diagnosis or symptomatology, were included. Nine trials (five ketamine and four MDMA) met inclusion criteria. Trials were rated on a quality and bias checklist and GRADE was used to rank the evidence. The evidence for ketamine as a stand-alone treatment for comorbid PTSD and depression was ranked "very low", and the evidence for ketamine in combination with psychotherapy as a PTSD treatment was ranked "low". The evidence for MDMA in combination with psychotherapy as a PTSD treatment was ranked "moderate".

Probability of major depression diagnostic classification based on the SCID, CIDI and MINI diagnostic interviews controlling for Hospital Anxiety and Depression Scale - Depression subscale scores: An individual participant data meta-analysis of 73 primary studies. J Psychosom Res 2020; 129:109892. [PMID: 31911325 DOI: 10.1016/j.jpsychores.2019.109892] [Citation(s) in RCA: 26] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/18/2019] [Revised: 12/10/2019] [Accepted: 12/11/2019] [Indexed: 02/01/2023]
Abstract
OBJECTIVE Two previous individual participant data meta-analyses (IPDMAs) found that different diagnostic interviews classify different proportions of people as having major depression overall or by symptom levels. We compared the odds of major depression classification across diagnostic interviews among studies that administered the Depression subscale of the Hospital Anxiety and Depression Scale (HADS-D). METHODS Data accrued for an IPDMA on HADS-D diagnostic accuracy were analysed. We fit binomial generalized linear mixed models to compare odds of major depression classification for the Structured Clinical Interview for DSM (SCID), Composite International Diagnostic Interview (CIDI), and Mini International Neuropsychiatric Interview (MINI), controlling for HADS-D scores and participant characteristics with and without an interaction term between interview and HADS-D scores. RESULTS There were 15,856 participants (1942 [12%] with major depression) from 73 studies, including 15,335 (97%) non-psychiatric medical patients, 164 (1%) partners of medical patients, and 357 (2%) healthy adults. The MINI (27 studies, 7345 participants, 1066 major depression cases) classified participants as having major depression more often than the CIDI (10 studies, 3023 participants, 269 cases) (adjusted odds ratio [aOR] = 1.70 (0.84, 3.43)) and the semi-structured SCID (36 studies, 5488 participants, 607 cases) (aOR = 1.52 (1.01, 2.30)). The odds ratio for major depression classification with the CIDI was less likely to increase as HADS-D scores increased than for the SCID (interaction aOR = 0.92 (0.88, 0.96)). CONCLUSION Compared to the SCID, the MINI may diagnose more participants as having major depression, and the CIDI may be less responsive to symptom severity.

Abstract
Despite its high prevalence in clinical and consultant liaison psychiatry populations, adjustment disorder research has traditionally been hindered by its lack of clear diagnostic criteria. However, with the greater diagnostic clarity provided in the Diagnostic and Statistical Manual of Mental Disorders – fifth edition (DSM-5) and the International Statistical Classification of Diseases and Related Health Problems, 11th edition (ICD-11), adjustment disorder has been increasingly recognised as an area of research interest. This paper evaluates the commonalities and differences between the ICD-11 and DSM-5 concepts of adjustment disorder and reviews the current state of knowledge regarding its symptom profile, course, assessment, and treatment. In doing so, it identifies the gaps in our understanding of adjustment disorder and discusses future directions for research.

The role of site and severity of injury as predictors of mental health outcomes following traumatic injury. Stress Health 2018; 34:545-551.

Abstract
The aim of this study was to investigate the influence of injury site and severity as predictors of mental health outcomes in the initial 12 months following traumatic injury. Using a multisite, longitudinal study, participants with a traumatic physical injury (N = 1,098) were assessed during hospital admission and followed up at 3 months (N = 932, 86%) and at 12 months (N = 715, 71%). Injury site was measured using the Abbreviated Injury Scale 90, and objective injury severity was measured using the Injury Severity Score. Participants also completed the Hospital Anxiety and Depression Scale and the Clinician Administered Post-traumatic Stress Disorder (PTSD) Scale. A random intercept mixed modelling analysis was conducted to evaluate the effects of site and severity of injury in relation to anxiety, PTSD, and depressive symptoms. Injury severity, as well as head and facial injuries, was predictive of elevated PTSD symptoms, and external injuries were associated with both PTSD and depression severity. In contrast, lower extremity injuries were associated with depressive and anxiety symptoms. The findings suggest that visible injuries are predictive of reduced mental health, particularly PTSD following traumatic injury. This has clinical implications for further advancing the screening for vulnerable injured trauma survivors at risk of chronic psychopathology.

Abstract
Adjustment disorder is a common psychiatric disorder, yet knowledge of the efficacious treatments for adjustment disorder is limited. In this systematic review, we aimed to examine psychological and pharmacological interventions that target adjustment disorder in adults to determine which interventions have the best evidence for improving adjustment disorder symptoms. We performed database searches for literature published between January 1980 and September 2016 and identified studies that included both a sample majority of individuals diagnosed with adjustment disorder and findings on adjustment disorder symptom outcomes. There were 29 studies that met the inclusion criteria for qualitative synthesis; the majority of studies (59%) investigated psychological therapies rather than pharmacological treatments (35%). The range of psychological therapies tested was diverse, with the majority containing cognitive behavioral therapy (CBT) components (53%), followed by three studies that were psychodynamic-related, three studies that were behavioral therapy-based, and two studies that involved relaxation techniques. We rated individual studies using a modified National Health and Medical Research Council quality and bias checklist and then used the Grading of Recommendations Assessment, Development and Evaluation (GRADE; Grade Working Group, 2004) system to rate the overall quality of the evidence. Despite several randomized controlled trials, the quality of the evidence for positive effects of all psychological and pharmacological treatments on symptoms of adjustment disorder was ranked as low to very low. Future high-quality research in the treatment of adjustment disorder has the potential to make a significant difference to individuals who struggle to recover after stressful events.

Abstract
BACKGROUND Although perceived social support is thought to be a strong predictor of psychological outcomes following trauma exposure, the temporal relationship between perceived positive and negative social support and post-traumatic stress disorder (PTSD) symptoms has not been empirically established. This study investigated the temporal sequencing of perceived positive social support, perceived negative social support, and PTSD symptoms in the 6 years following trauma exposure among survivors of traumatic injury. METHOD Participants were 1132 trauma survivors initially assessed upon admission to one of four Level 1 trauma hospitals in Australia after experiencing a traumatic injury. Participants were followed up at 3 months, 12 months, 24 months, and 6 years after the traumatic event. RESULTS Latent difference score analyses revealed that greater severity of PTSD symptoms predicted subsequent increases in perceived negative social support at each time-point. Greater severity of PTSD symptoms predicted subsequent decreases in perceived positive social support between 3 and 12 months. High levels of perceived positive or negative social support did not predict subsequent changes in PTSD symptoms at any time-point. CONCLUSIONS Results highlight the impact of PTSD symptoms on subsequent perceived social support, regardless of the type of support provided. The finding that perceived social support does not influence subsequent PTSD symptoms is novel, and indicates that the relationship between PTSD and perceived social support may be unidirectional.

Abstract
OBJECTIVE Adjustment disorder has been recategorized as a trauma- and stressor-related disorder in DSM-5. The aim of this study was to determine the prevalence of adjustment disorder in the first 12 months after severe injury; to determine whether adjustment disorder was a less severe disorder compared with other disorders in terms of disability and quality of life; to investigate the trajectory of adjustment disorder; and to examine whether the subtypes described in DSM-5 are distinguishable. METHOD In a multisite, cohort study, injury patients were assessed during hospitalization and at 3 and 12 months postinjury (N=826). Structured clinical interviews were used to assess affective, anxiety, and substance use disorders, and self-report measures of disability, anxiety, depression, and quality of life were administered. RESULTS The prevalence of adjustment disorder was 19% at 3 months and 16% at 12 months. Participants with adjustment disorder reported worse outcomes relative to those with no psychiatric diagnosis but better outcomes compared with those diagnosed with other psychiatric disorders. Participants with adjustment disorder at 3 months postinjury were significantly more likely to meet criteria for a psychiatric disorder at 12 months (odds ratio=2.67, 95% CI=1.59-4.49). Latent-profile analysis identified a three-class model that was based on symptom severity, not the subtypes identified by DSM-5. CONCLUSIONS Recategorization of adjustment disorder into the trauma- and stressor-related disorders is supported by this study. However, further description of the phenomenology of the disorder is required.

Abstract
OBJECTIVE Although traumatic injuries affect millions of patients each year and increase risk for psychiatric disorder, no evidence currently exists regarding associated suicidal risk. This study reports a longitudinal investigation of suicidal risk in the 2 years after traumatic injury. METHODS A prospective design cohort study was conducted in 4 major trauma hospitals across Australia. A total of 1,129 traumatically injured patients were assessed during hospital admission between April 2004 and February 2006 and were followed up at 3 months (88%), 12 months (77%), and 24 months (72%). Lifetime psychiatric disorder was assessed in hospital using the Mini-International Neuropsychiatric Interview, version 5.5, which was also used to assess the prevalence of suicidality, psychiatric disorder, and exposure to adverse life events at 3, 12, and 24 months after traumatic injury. RESULTS Approximately 6% of patients reported moderate/high suicidal risk at each assessment. At each assessment, half of suicidal patients reported no suicidal risk at the previous assessment. Suicidality at 24 months was predicted by current pain levels (odds ratio [OR] = 1.16; 95% CI, 1.09-1.23), recent life events (OR = 1.30; 95% CI,1.17-1.44), and current psychiatric disorder (OR = 17.07; 95% CI, 7.03-41.42), whereas only 36.6% of suicidal patients had consulted a mental health professional in the previous month, and 66.2% had consulted a primary care physician. CONCLUSIONS Suicidal risk affects a significant proportion of patients who experience a traumatic injury, and the risk for suicide fluctuates markedly in the initial years following the injury. Primary care physicians need to be trained to assess for suicidal risk in the initial years after a traumatic injury.

Abstract
BACKGROUND Anxiety and depression are common following traumatic brain injury (TBI), often co-occurring. This study evaluated the efficacy of a 9-week cognitive behavioral therapy (CBT) program in reducing anxiety and depression and whether a three-session motivational interviewing (MI) preparatory intervention increased treatment response. METHOD A randomized parallel three-group design was employed. Following diagnosis of anxiety and/or depression using the Structured Clinical Interview for DSM-IV, 75 participants with mild-severe TBI (mean age 42.2 years, mean post-traumatic amnesia 22 days) were randomly assigned to an Adapted CBT group: (1) MI + CBT (n = 26), or (2) non-directive counseling (NDC) + CBT (n = 26); or a (3) waitlist control (WC, n = 23) group. Groups did not differ in baseline demographics, injury severity, anxiety or depression. MI and CBT interventions were guided by manuals adapted for individuals with TBI. Three CBT booster sessions were provided at week 21 to intervention groups. RESULTS Using intention-to-treat analyses, random-effects regressions controlling for baseline scores revealed that Adapted CBT groups (MI + CBT and NDC + CBT) showed significantly greater reduction in anxiety on the Hospital Anxiety and Depression Scale [95% confidence interval (CI) -2.07 to -0.06] and depression on the Depression Anxiety and Stress Scale (95% CI -5.61 to -0.12) (primary outcomes), and greater gains in psychosocial functioning on Sydney Psychosocial Reintegration Scale (95% CI 0.04-3.69) (secondary outcome) over 30 weeks post-baseline relative to WC. The group receiving MI + CBT did not show greater gains than the group receiving NDC + CBT. CONCLUSIONS Findings suggest that modified CBT with booster sessions over extended periods may alleviate anxiety and depression following TBI.

Abstract
OBJECTIVE The impact of mental health on disease burden associated with injury represents a major public health issue, yet almost no information is available on the associated long-term mental health outcomes. The primary aim of this study was to assess the psychiatric outcomes 6 years after a severe injury and their subsequent impact on long-term disability. The secondary aim was to investigate the relationship between a mild traumatic brain injury (mTBI) and long-term psychiatric disorder and its impact on disability. METHODS From April 2004 to February 2006, randomly selected injury patients admitted to 4 hospitals across Australia were assessed during hospitalization and at 72 months after trauma (N = 592). Injury characteristics, the presence of an mTBI (ICD-9 criteria), and previous psychiatric history were assessed during hospitalization. Structured clinical interviews for psychiatric disorders (DSM-IV and DSM-5) and a self-report measure of disability (WHODAS II) were administered at 72 months. RESULTS At 72 months after a severe injury, 28% of patients met criteria for at least 1 psychiatric disorder, with 45% of those presenting with comorbid diagnoses. The most prevalent psychiatric disorder was a major depressive episode (11%) followed by substance use disorder (9%), agoraphobia (9%), posttraumatic stress disorder (6%), and generalized anxiety disorder (6%). The presence of any psychiatric disorder was found to increase the risk for disability (P < .001, odds ratio = 6.04). An mTBI was found to increase the risk for having some anxiety disorders but not to increase disability by itself. CONCLUSIONS The long-term psychiatric consequences of severe injury are substantial and represent a significant contributor to long-term disability. This study points to an important intersection between injury and psychiatric disorder as a leading contributor to disease burden and suggests this growing burden will impose new challenges on health systems.

Compensation seeking and disability after injury: the role of compensation-related stress and mental health. J Clin Psychiatry 2015; 76:e1000-5.

Abstract
OBJECTIVE Claiming for compensation after injury is associated with poor health outcomes. This study examined the degree to which compensation-related stress predicts long-term disability and the mental health factors that contribute to this relationship. METHOD In a longitudinal, multisite cohort study, 332 injury patients (who claimed for compensation) recruited from April 2004 to February 2006 were assessed during hospitalization and at 3 and 72 months after injury. Posttraumatic stress, depression, and anxiety symptoms (using the Mini-International Neuropsychiatric Interview) were assessed at 3 months; compensation-related stress and disability levels (using the World Health Organization Disability Assessment Schedule II) were assessed at 72 months. RESULTS A significant direct relationship was found between levels of compensation-related stress and levels of long-term disability (β = 0.35, P < .001). Three-month posttraumatic stress symptoms had a significant relationship with compensation-related stress (β = 0.29, P < .001) as did 3-month depression symptoms (β = 0.39, P < .001), but 3-month anxiety symptoms did not. A significant indirect relationship was found for posttraumatic stress symptoms and disability via compensation stress (β = 0.099, P = .001) and for depression and disability via compensation stress (β = 0.136, P < .001). CONCLUSIONS Stress associated with seeking compensation is significantly related to long-term disability. Posttraumatic stress and depression symptoms increase the perception of stress associated with the claims process, which in turn is related to higher levels of long-term disability. Early interventions targeting those at risk for compensation-related stress may decrease long-term costs for compensation schemes.

Abstract
OBJECTIVE This longitudinal study investigated the temporal relationship patterns between disability and mental health after injury, with a focus on posttraumatic stress disorder (PTSD), depression, and anxiety. METHOD We conducted a multi-sited longitudinal cohort study with a large sample of hospital patients admitted after injury (N = 1,149, mean age = 37.9, 73.6% male). Data were collected prior to discharge from hospital, and follow-up assessments took place 3 and 12 months postinjury. A cross-lagged structural equation model (SEM) was used to assess the prospective relationship between posttraumatic stress, anxiety, and depression symptoms and disability while controlling for demographic characteristics and objective measures of injury severity. RESULTS Acute depression significantly predicted 3-month disability, and 3-month PTSD severity significantly predicted 12-month disability. Premorbid disability had a significant effect on acute anxiety, depression, and posttraumatic stress symptoms, and 3-month depression but disability after the injury did not predict 12-month psychopathology. CONCLUSIONS We did not find a reciprocal relationship between disability and psychopathology. Rather we found that depression played a role in early disability while PTSD played a role in contributing to long-term delays in the recovery process. The results of this study highlight the need for mental health screening for symptoms of PTSD and depression in the acute aftermath of trauma, combined with early intervention programs in injury populations.

Abstract
BACKGROUND Most of what we know about the psychiatric consequences of injury is limited to the first year. Determining the prevalence of and risk factors for psychiatric morbidity beyond one year will aid service development and facilitate timely diagnosis and treatment. The aim of this prognostic study was to determine the prevalence of mental disorders in the three years following serious injury and to identify risk factors for the onset of new disorders after 1 year. METHODS Of 272 patients assessed in hospital following serious injury, 196 (72.1%) were reassessed at 3 years. Assessment involved gold standard semi-structured interviews for psychiatric diagnoses, risk factors for mental disorder, injury measures and pain scores. RESULTS More than a quarter of all patients were diagnosed with at least one mood or anxiety disorder at some stage during the three years following their injury. The most common diagnoses were major depression (20.0%), generalised anxiety disorder (6.7%) and panic disorder (6.7%). For a third of these patients, the disorder appeared after 12 months, for which persistent physical disability was an independent risk factor. CONCLUSION Although there is a necessary focus on the early detection and treatment of mental disorders after injury, attention to later onset disorders is also required for those with persistent pain and physical disability.

Abstract
BACKGROUND There have been changes to the criteria for diagnosing post-traumatic stress disorder (PTSD) in DSM-5 and changes are proposed for ICD-11. AIMS To investigate the impact of the changes to diagnostic criteria for PTSD in DSM-5 and the proposed changes in ICD-11 using a large multisite trauma-exposed sample and structured clinical interviews. METHOD Randomly selected injury patients admitted to four hospitals were assessed 72 months post trauma (n = 510). Structured clinical interviews for PTSD and major depressive episode, as well as self-report measures of disability and quality of life were administered. RESULTS Current prevalence of PTSD under DSM-5 scoring was not significantly different from DSM-IV (6.7% v. 5.9%, z = 0.53, P = 0.59). However, the ICD-11 prevalence was significantly lower than ICD-10 (3.3% v. 9.0%, z = -3.8, P<0.001). The PTSD current prevalence was significantly higher for DSM-5 than ICD-11 (6.7% v. 3.3%, z = 2.5, P = 0.01). Using ICD-11 tended to show lower rates of comorbidity with depression and a slightly lower association with disability. CONCLUSIONS The diagnostic systems performed in different ways in terms of current prevalence rates and levels of comorbidity with depression, but on other broad key indicators they were relatively similar. There was overlap between those with PTSD diagnosed by ICD-11 and DSM-5 but a substantial portion met one but not the other set of criteria. This represents a challenge for research because the phenotype that is studied may be markedly different according to the diagnostic system used.

Abstract
BACKGROUND Approximately one in five children who sustain a serious injury develops persistent stress symptoms. Emergency Department nurses and physicians have a pivotal role in psychosocial care for seriously injured children. However, little is known about staff's views on this role. OBJECTIVE Our aim was to investigate Emergency Department staff's views on psychosocial care for seriously injured children. METHODS We conducted semi-structured interviews with 20 nurses and physicians working in an Australian Paediatric Emergency Department. We used purposive sampling to obtain a variety of views. The interviews were transcribed verbatim and major themes were derived in line with the summative analysis method. We also mapped participants' strategies for child and family support on the eight principles of Psychological First Aid (PFA). RESULTS Five overarching themes emerged: (1) staff find psychosocial issues important but focus on physical care; (2) staff are aware of individual differences but have contrasting views on vulnerability; (3) parents have a central role; (4) staff use a variety of psychosocial strategies to support children, based on instinct and experience but not training; and (5) staff have individually different wishes regarding staff- and self-care. Staff elaborated most on strategies related to the PFA elements 'contact and engagement', 'stabilization', 'connection with social supports' and least on 'informing about coping'. CONCLUSIONS The strong notion of individual differences in views suggests a need for training in psychosocial care for injured children and their families. In addition, further research on paediatric traumatic stress and psychosocial care in the ED will help to overcome the current paucity of the literature. Finally, a system of peer support may accommodate wishes regarding staff care.

Relationship between stressfulness of claiming for injury compensation and long-term recovery: a prospective cohort study. JAMA Psychiatry 2014; 71:446-53.

Abstract
IMPORTANCE Each year, millions of persons worldwide seek compensation for transport accident and workplace injuries. Previous research suggests that these claimants have worse long-term health outcomes than persons whose injuries fall outside compensation schemes. However, existing studies have substantial methodological weaknesses and have not identified which aspects of the claiming experience may drive these effects. OBJECTIVE To determine aspects of claims processes that claimants to transport accident and workers' compensation schemes find stressful and whether such stressful experiences are associated with poorer long-term recovery. DESIGN, SETTING, AND PARTICIPANTS Prospective cohort study of a random sample of 1010 patients hospitalized in 3 Australian states for injuries from 2004 through 2006. At 6-year follow-up, we interviewed 332 participants who had claimed compensation from transport accident and workers' compensation schemes ("claimants") to determine which aspects of the claiming experience they found stressful. We used multivariable regression analysis to test for associations between compensation-related stress and health status at 6 years, adjusting for baseline determinants of long-term health status and predisposition to stressful experiences (via propensity scores). MAIN OUTCOMES AND MEASURES Disability, quality of life, anxiety, and depression. RESULTS Among claimants, 33.9% reported high levels of stress associated with understanding what they needed to do for their claim; 30.4%, with claim delays; 26.9%, with the number of medical assessments; and 26.1%, with the amount of compensation they received. Six years after their injury, claimants who reported high levels of stress had significantly higher levels of disability (+6.94 points, World Health Organization Disability Assessment Schedule sum score), anxiety and depression (+1.89 points and +2.61 points, respectively, Hospital Anxiety and Depression Scale), and lower quality of life (-0.73 points, World Health Organization Quality of Life instrument, overall item), compared with other claimants. Adjusting for claimants' vulnerability to stress attenuated the strength of these associations, but most remained strong and statistically significant. CONCLUSIONS AND RELEVANCE Many claimants experience high levels of stress from engaging with injury compensation schemes, and this experience is positively correlated with poor long-term recovery. Intervening early to boost resilience among those at risk of stressful claims experiences and redesigning compensation processes to reduce their stressfulness may improve recovery and save money.

Abstract
IMPORTANCE Delayed-onset posttraumatic stress disorder (PTSD) accounts for approximately 25% of PTSD cases. Current models do not adequately explain the delayed increases in PTSD symptoms after trauma exposure. OBJECTIVE To test the roles of initial psychiatric reactions, mild traumatic brain injury (MTBI), and ongoing stressors on delayed-onset PTSD. DESIGN, SETTING, AND PARTICIPANTS In this prospective cohort study, patients were selected from recent admissions to 4 major trauma hospitals across Australia. A total of 1084 traumatically injured patients were assessed during hospital admission from April 1, 2004, through February 28, 2006, and 785 (72.4%) were followed up at 3, 12, and 24 months after injury. MAIN OUTCOME AND MEASURE Severity of PTSD was determined at each assessment with the Clinician-Administered PTSD Scale. RESULTS Of those who met PTSD criteria at 24 months, 44.1% reported no PTSD at 3 months and 55.9% had subsyndromal or full PTSD. In those who displayed subsyndromal or full PTSD at 3 months, PTSD severity at 24 months was predicted by prior psychiatric disorder, initial PTSD symptom severity, and type of injury. In those who displayed no PTSD at 3 months, PTSD severity at 24 months was predicted by initial PTSD symptom severity, MTBI, length of hospitalization, and the number of stressful events experienced between 3 and 24 months. CONCLUSIONS AND RELEVANCE These data highlight the complex trajectories of PTSD symptoms over time. This study also points to the roles of ongoing stress and MTBI in delayed cases of PTSD and suggests the potential of ongoing stress to compound initial stress reactions and lead to a delayed increase in PTSD symptom severity. This study also provides initial evidence that MTBI increases the risk of delayed PTSD symptoms, particularly in those with no acute symptoms.

Disability after injury: the cumulative burden of physical and mental health. J Clin Psychiatry 2013; 74:e137-43. [PMID: 23473359 DOI: 10.4088/jcp.12m08011] [Citation(s) in RCA: 73] [Impact Index Per Article: 6.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/11/2012] [Accepted: 10/04/2012] [Indexed: 10/27/2022]
Abstract
CONTEXT Injury is one of the leading contributors to the global burden of disease. The factors that drive long-term disability after injury are poorly understood. OBJECTIVE The main aim of the study was to model the direct and indirect pathways to long-term disability after injury. Specifically, the relationships between 3 groups of variables and long-term disability were examined over time. These included physical factors (including injury characteristics and premorbid disability), pain severity (including pain at 1 week and 12 months), and psychiatric symptoms (including psychiatric history and posttraumatic stress, depression, and anxiety symptoms at 1 week and 12 months). DESIGN, SETTING, AND PARTICIPANTS A multisite, longitudinal cohort study of 715 randomly selected injury patients (from April 2004 to February 2006). Participants were assessed just prior to discharge (mean = 7.0 days, SD = 7.8 days) and reassessed at 12 months postinjury. Injury patients who experienced moderate/severe traumatic brain injury and spinal cord injury were excluded from the study. MAIN OUTCOME MEASURE The World Health Organization Disability Assessment Schedule 2.0 was used to assess disability at 12 months after injury. RESULTS Disability at 12 months was up to 4 times greater than community norms, across all age groups. The development and maintenance of long-term disability occurred through a complex interaction of physical factors, pain severity across time, and psychiatric symptoms across time. While both physical factors and pain severity contributed significantly to 12-month disability (pain at 1 week: total effect [TE] = 0.2, standard error [SE] < 0.1; pain at 12 months: TE = 0.3, SE < 0.1; injury characteristics: TE = 0.3, SE < 0.1), the total effects of psychiatric symptoms were substantial (psychiatric symptoms 1 week: TE = 0.30, SE < 0.1; psychiatric symptoms 12 months: TE = 0.71, SE < 0.1). Taken together, psychiatric symptoms accounted for the largest proportion of the variance in disability at 12 months. CONCLUSIONS While the physical and pain consequences of injury contribute significantly to enduring disability after injury, psychiatric symptoms play a greater role. Early interventions targeting psychiatric symptoms may play an important role in improving functional outcomes after injury.

Abstract
The best approach for implementing early psychological intervention for anxiety and depressive disorders after a traumatic event has not been established. This study aimed to test the effectiveness of a stepped model of early psychological intervention following traumatic injury. A sample of 683 consecutively admitted injury patients were screened during hospitalization. High-risk patients were followed up at 4-weeks postinjury and assessed for anxiety and depression symptom levels. Patients with elevated symptoms were randomly assigned to receive 4-10 sessions of cognitive-behavioral therapy (n = 24) or usual care (n = 22). Screening in the hospital identified 89% of those who went on to develop any anxiety or affective disorder at 12 months. Relative to usual care, patients receiving early intervention had significantly improved mental health at 12 months. A stepped model can effectively identify and treat injury patients with high psychiatric symptoms within 3 months of the initial trauma.

Abstract
Reexperiencing symptoms are a key feature of posttraumatic stress disorder (PTSD). This study investigated the pattern of reexperiencing symptoms in non-PTSD posttraumatic disorders. This study recruited 1084 traumatically injured patients during hospital admission and conducted follow-up assessment 12 months later (N = 817, 75%). Twelve months after injury, 22% of patients reported a psychiatric disorder they had never experienced prior to the traumatic injury. One-third of patients with a non-PTSD disorder satisfied the PTSD reexperiencing criteria. Whereas patients with a non-PTSD disorder were more likely to experience intrusive memories, nightmares, psychological distress and physiological reactivity to reminders, only patients with PTSD were likely to experience flashback memories (OR: 11.41, 95% CI: 6.17-21.09). The only other symptom that was distinctive to PTSD was dissociative amnesia (OR: 4.50, 95% CI: 2.09-9.71). Whereas intrusive memories and reactions are common across posttraumatic disorders, flashbacks and dissociative amnesia are distinctive to PTSD.

Abstract
OBJECTIVE To conduct a descriptive study investigating the effect of access to motor vehicle accident (MVA) compensation on recovery outcomes at 24 months after injury. DESIGN AND SETTING Longitudinal cohort study conducted in two Level 1 trauma hospitals in Victoria, Australia. Participants were 391 randomly selected injury patients with moderate-to-severe injuries. Compensable and non-compensable patients were compared at 24 months after injury on a number of health outcomes. MAIN OUTCOME MEASURES Health outcomes at 24 months, including anxiety and depression severity, quality of life and disability. RESULTS Medical records identified two groups of compensation patients: MVA-compensable and non-compensable patients. After controlling for baseline variables, the MVA-compensable patients, at 24 months, had higher levels of post-traumatic stress disorder, anxiety and depression, and were less likely to have returned to their pre-injury number of work hours. However, some patients in the non-compensable group had accessed other forms of compensation (eg, private health care or compensation for victims of crime). When these were removed from the non-compensable group, the differences between MVA-compensable and non-compensable groups all but disappeared. CONCLUSION Our findings do not support previous research showing that access to compensation is associated with poor recovery outcomes. The relationship between access to compensation and health outcomes is complex, and more high-level research is required.

Abstract
OBJECTIVE Traumatic injury affects millions of people each year. There is little understanding of the extent of psychiatric illness that develops after traumatic injury or of the impact of mild traumatic brain injury (TBI) on psychiatric illness. The authors sought to determine the range of new psychiatric disorders occurring after traumatic injury and the influence of mild TBI on psychiatric status. METHOD In this prospective cohort study, patients were drawn from recent admissions to four major trauma hospitals across Australia. A total of 1,084 traumatically injured patients were initially assessed during hospital admission and followed up 3 months (N=932, 86%) and 12 months (N=817, 75%) after injury. Lifetime psychiatric diagnoses were assessed in hospital. The prevalence of psychiatric disorders, levels of quality of life, and mental health service use were assessed at the follow-ups. The main outcome measures were 3- and 12-month prevalence of axis I psychiatric disorders, levels of quality of life, and mental health service use and lifetime axis I psychiatric disorders. RESULTS Twelve months after injury, 31% of patients reported a psychiatric disorder, and 22% developed a psychiatric disorder that they had never experienced before. The most common new psychiatric disorders were depression (9%), generalized anxiety disorder (9%), posttraumatic stress disorder (6%), and agoraphobia (6%). Patients were more likely to develop posttraumatic stress disorder (odds ratio=1.92, 95% CI=1.08-3.40), panic disorder (odds ratio=2.01, 95% CI=1.03-4.14), social phobia (odds ratio=2.07, 95% CI=1.03-4.16), and agoraphobia (odds ratio=1.94, 95% CI=1.11-3.39) if they had sustained a mild TBI. Functional impairment, rather than mild TBI, was associated with psychiatric illness. CONCLUSIONS A significant range of psychiatric disorders occur after traumatic injury. The identification and treatment of a range of psychiatric disorders are important for optimal adaptation after traumatic injury.

Abstract
OBJECTIVE Previous studies investigating the relationship between acute stress disorder (ASD) and posttraumatic stress disorder (PTSD) have reported mixed findings and have been flawed by small sample sizes and single sites. This study addresses these limitations by conducting a large-scale and multisite study to evaluate the extent to which ASD predicts subsequent PTSD. METHOD Between April 2004 and April 2005, patients admitted consecutively to 4 major trauma hospitals across Australia (N = 597) were randomly selected and assessed for ASD (DSM-IV criteria) during hospital admission (within 1 month of trauma exposure) and were subsequently reassessed for PTSD 3 months after the initial assessment (N = 507). RESULTS Thirty-three patients (6%) met criteria for ASD, and 49 patients (10%) met criteria for PTSD at the 3-month follow-up assessment. Fifteen patients (45%) diagnosed with ASD and 34 patients (7%) not diagnosed with ASD subsequently met criteria for PTSD. The positive predictive power of PTSD criteria in the acute phase (0.60) was a better predictor of chronic PTSD than the positive predictive power of ASD (0.46). CONCLUSIONS The majority of people who develop PTSD do not initially meet criteria for ASD. These data challenge the proposition that the ASD diagnosis is an adequate tool to predict chronic PTSD.

Abstract
In 2005, over 2 million people in the United States of America were hospitalised following non-fatal injuries. The frequency with which severe injury occurs renders it a leading cause of posttraumatic stress disorder and other trauma-related psychopathology. In order to develop a health system model of early psychological intervention for this population, we review the literature that pertains to mental health early intervention. The relevant domains include prevalence of psychopathology following traumatic injury, the course of symptoms, screening, and early intervention strategies. On the basis of available evidence, we propose a health system model of early psychological intervention following traumatic injury. The model involves screening for vulnerability within the hospital setting, follow-up screening for persistent symptoms at one month posttrauma, and early psychological intervention for those who are experiencing clinical impairment. Recommendations are made to facilitate tailoring early intervention psychological therapies to the special needs of the injury population.

Abstract
OBJECTIVE To examine the relationship between acute measures of a) heart rate (HR) immediately after traumatic injury, b) tonic (resting) HR at 1 week post injury, c) phasic (aroused) HR at 1 week post injury, and d) somatic symptoms of arousal in the prediction of subsequent posttraumatic stress disorder (PTSD). Fear conditioning models propose that HR reactivity shortly after trauma may predict PTSD. METHOD In a longitudinal study, consecutive injury survivors (n = 197) admitted to a hospital trauma service were assessed within 1 week and at 12 months post injury. HR was assessed by paramedics at the site of the trauma and pulse oximetry technology at 1 week post trauma. Somatic symptoms of arousal were measured using the somatic scale on the Beck Anxiety Inventory (BAI). PTSD was assessed using the Clinician Administered PTSD Scale at 12 months. RESULTS At 12 months post injury, PTSD was diagnosed in 10% of participants. Only HR change scores (phasic - tonic HR) and BAI scores significantly predicted later PTSD. CONCLUSIONS These findings question the clinical usefulness of tonic HR as a biological marker of later PTSD. The finding that HR reactivity (phasic - tonic) predicts later PTSD has theoretical importance. The strongest predictor of later PTSD was somatic arousal.

Abstract
Cognitive models of posttraumatic stress disorder (PTSD) posit that appraisal plays an important role in the development and persistence of PTSD. This study examined posttraumatic appraisals and their relationship to the development and course of PTSD symptoms. Two hundred fifty-three injury survivors were assessed for PTSD symptoms and posttraumatic cognitions across a 12-month period. A path analytic modeling approach showed that posttraumatic appraisals were important direct and indirect predictors of later PTSD severity. The findings suggest that appraisals made in the aftermath of trauma have a significant influence on subsequent psychological adjustment.

Abstract
This study aimed to identify posttraumatic stress disorder (PTSD) symptom trajectories across the first 12 months following traumatic injury. Three hundred and seven consecutively admitted injury survivors were assessed for severity of PTSD symptoms just prior to discharge, and at 3 and 12 months postinjury. Growth modeling was used to determine the curve that best fit the trajectory for each symptom cluster over the 12-month period. Individuals with 12-month PTSD showed significantly higher re-experiencing, arousal, and avoidance symptoms at eight days posttrauma relative to those without, and these symptoms escalated over time. Those without PTSD maintained their relatively low symptom levels. These findings highlight that individuals who will go onto develop PTSD have a distinctly different symptom course than those who recover.

Abstract
This study explored the relationship between mild traumatic brain injury (MTBI), amnesia, and posttraumatic stress disorder (PTSD). MTBI status and amnesia for the event were assessed in 307 consecutive admissions to a Level 1 Trauma Center. Amnesia did not always occur concurrently with MTBI: 18% of those with MTBI had full recall and over half had partial recall of the event. Just over 10% of participants developed PTSD by 12 months post-injury, with prevalence comparable across MTBI and non-MTBI groups. Non-significant differences in incidence of PTSD were apparent between those with full recall (9%), partial recall (14%) and no recall (7%). These data highlight the fact that PTSD may develop following trauma despite amnesia for the event, and illustrate the importance in both clinical and research settings of carefully examining the extent of amnesia.

Abstract
BACKGROUND Recent studies have indicated that delayed-onset posttraumatic stress disorder (PTSD) (i.e., the development of PTSD more than 6 months posttrauma) is generally characterised by subsyndromal diagnoses within the first 6 months. This study sought to examine the relationship between sub-clinical levels of PTSD symptoms at 3 months posttrauma and delayed onset PTSD at 12 months in a large sample of traumatic injury survivors. METHODS Three hundred and one consecutively admitted injury survivors were assessed at 3 and 12 months posttrauma. PTSD was diagnosed according to DSM-IV criteria, while partial and subsyndromal diagnoses were based on recent definitions developed by Mylle and Maes [Mylle, J., Maes, M., 2004. Partial posttraumatic stress disorder revisited. J. Affect. Disord. 78, 37-48]. RESULTS Eight percent of participants was diagnosed with 3-month PTSD while 10% was diagnosed with 12-month PTSD. Nearly half (47%) of 12-month PTSD cases were of delayed onset. The majority of those with delayed-onset were diagnosed with partial or subsyndromal PTSD at 3 months. Ten percent of delayed onset cases did not meet partial or subsyndromal criteria. LIMITATIONS As symptoms were not assessed at 6 months (the DSM cut-off for delayed PTSD), it could not be conclusively determined that delayed-onset cases had not developed PTSD between 3 and 6 months posttrauma. CONCLUSION A considerable proportion of 12-month PTSD diagnoses was delayed in onset. While most demonstrated 3-month morbidity in the form of partial and subsyndromal diagnoses, a minority did not. Thus, clinicians should consider subthreshold diagnoses as potential risk factors for delayed-onset PTSD. Future research is required to identify factors that may predict delayed-onset PTSD in trauma survivors without evidence of prior PTSD pathology.

Abstract
BACKGROUND The factors that determine quality of life (QOL) and disability after traumatic injury are poorly understood. This study identified the unique contributions that characteristics about the injury/hospital admission and acute psychological adjustment make in determining 12-month role-related disability and QOL. METHODS Consecutive admissions (n = 363) to a Level I trauma service were assessed just before discharge and followed up at 12 months. Structural equational modeling was used to examine the relationships between the acute factors and 12-month outcomes. RESULTS Characteristics of the individual's injuries measured in the acute setting significantly predicted 12-month disability but only indirectly predicted 12-month QOL. An individual's acute psychological response directly predicted both the level of disability and QOL at 12 months. CONCLUSIONS Both characteristics about an individual's injury and acute psychological responses play important roles in determining later QOL and role-related disability outcomes. Trauma care systems must consider both physical and psychological injury to offer effective and comprehensive healthcare management.
