Assessing psychological adjustment and cultural reintegration after military service: development and psychometric evaluation of the post-separation Military-Civilian Adjustment and Reintegration Measure (M-CARM)

Background: The transition out of military service and subsequent reintegration to civilian life has been established as a period associated with an increased risk of psychological adjustment difficulties, psychiatric disorders and suicide risk, yet no tool exists to measure cultural and psychological adjustment following permanent separation from the military. This study describes the two-phase mixed-methods development and validation of the self-report Military-Civilian Adjustment and Reintegration Measure (M-CARM). Methods: In Phase I, four focus groups (n = 20) and semi-structured one-on-one interviews (n = 80) enabled thematic analysis and generation of 53 initial items that were reviewed by an expert multidisciplinary panel (n = 12) and piloted for clarity and relevance in an Australian service-veteran sample (n = 11). In Phase II, psychometric properties of the 47 items resulting from Phase I were evaluated with online assessment of a convenience sample of transitioned Australian Defence Force veterans (n = 725). Analyses included exploratory and confirmatory factor analyses, as well as evaluation of test-retest reliability, internal consistency, and convergent, divergent and discriminant validity. Results: Exploratory factor analysis on a randomized split-half sample (n = 357), resulted in a 21-item, five-factor solution of Purpose and Connection, Help seeking, Beliefs about civilians, Resentment and regret, and Regimentation, explaining 53.22% of the variance. Confirmatory factor analysis (n = 368) verified this factor structure without modification (χ2 = 304.96, df = 160; CFI = .96, TLI = .94, NFI = .91, RMSEA = .05). Strong convergent, divergent and discriminant validity was demonstrated as M-CARM scores significantly correlated with related constructs assessed by standardised clinical measures as well as differentiated groups based on three binary reintegration items, with large effect sizes (d = > 1). Strong test-retest reliability for the total score (n = 186, r = .93) and excellent internal consistency (n = 725, a = .90) were also found. Conclusions: Results provide promising evidence the M-CARM is a valid, reliable measure of psychological and cultural reintegration to civilian life, with potential for considerable clinical and research application.This study was funded by RSL Queensland

University Student Depression Inventory (USDI) : confirmatory factor analysis and review of psychometric properties

Background: \ud The 30-item USDI is a self-report measure that assesses depressive symptoms among university students. It consists of three correlated three factors: Lethargy, Cognitive-Emotional and Academic motivation. The current research used confirmatory factor analysis to asses construct validity and determine whether the original factor structure would be replicated in a different sample. Psychometric properties were also examined. \ud \ud Method: \ud Participants were 1148 students (mean age 22.84 years, SD = 6.85) across all faculties from a large Australian metropolitan university. Students completed a questionnaire comprising of the USDI, the Depression Anxiety Stress Scale (DASS) and Life Satisfaction Scale (LSS). \ud \ud Results: \ud The three correlated factor model was shown to be an acceptable fit to the data, indicating sound construct validity. Internal consistency of the scale was also demonstrated to be sound, with high Cronbach Alpha values. Temporal stability of the scale was also shown to be strong through test-retest analysis. Finally, concurrent and discriminant validity was examined with correlations between the USDI and DASS subscales as well as the LSS, with sound results contributing to further support the construct validity of the scale. Cut-off points were also developed to aid total score interpretation. \ud \ud Limitations: \ud Response rates are unclear. In addition, the representativeness of the sample could be improved potentially through targeted recruitment (i.e. reviewing the online sample statistics during data collection, examining the representativeness trends and addressing particular faculties within the university that were underrepresented). \ud \ud Conclusions: \ud The USDI provides a valid and reliable method of assessing depressive symptoms found among university students

Evaluation of an equine-assisted therapy program for veterans who identify as 'wounded, injured or ill' and their partners

The aim of this study was to evaluate outcomes of an equine-assisted therapy program for Defence Force veterans and their partners across the psychological domains of depression, anxiety, stress, posttraumatic stress, happiness, and quality of life, as well as compare the outcomes of an Individual and Couples program. A non-controlled, within-subjects longitudinal design was utilized with assessment at three time points (pre-intervention, post-intervention, and three months follow-up). Between-subjects analysis with two groups was also conducted to compare the outcomes of the Individual and Couples programs. Participants were recruited from ten programs in 2016 with a total of 47 veterans and partners from both an Individual program (n = 25; veterans only) and a Couples program (n = 22). Outcome measures included the Depression Anxiety Stress Scale-21, Posttraumatic Stress Disorder Checklist for DSM-5, Oxford Happiness Questionnaire, and Quality-of-Life Enjoyment and Satisfaction Questionnaire-Short Form. Paired samples t-tests revealed that within both the Individual and Couples programs, there were significantly fewer psychological symptoms and significantly greater levels of happiness and quality of life at post-intervention compared to pre-intervention. Reduced psychological symptoms were maintained at the three months follow-up for participants of the Couples program only. Independent samples t-tests revealed participants in the Couples program reported significantly less symptoms of depression, stress, and posttraumatic stress disorder (PTSD) at follow-up compared to participants in the Individual program. These results indicate there may only be meaningful benefits for equine-assisted therapy in the reduction of depression, stress, and PTSD symptoms for veterans, if partners are integrated into the intervention

Evaluation of the online, peer delivered 'Post War: Survive to Thrive Program' for veterans with symptoms of posttraumatic stress disorder

Background: Veterans frequently report barriers to accessing and adhering to first-line treatments for posttraumatic stress disorder (PTSD). Online delivery of an evidence-based intervention by a peer-developed program may aid in overcoming these barriers.Purpose: This study evaluated the 'Post War: Survive to Thrive Program', an online, peer developed and delivered program, designed to assist with the management of commonly occurring mental health symptoms among veterans.Material and Methods: Former Australian Defence Force (ADF) members (n = 29) completed the program and were assessed at pre-intervention, three months post-commencement of the program (post-intervention) and six months post-commencement (follow-up). Changes in mental health symptoms were assessed using the DASS-21 and PTSD Checklist for DSM-5, and changes in overall levels of happiness were assessed using the Oxford Happiness Questionnaire.Results: Repeated measures ANOVAs indicated significant main effects across time for all constructs measured. Post-hoc comparisons indicated depression, anxiety, stress and posttraumatic stress symptoms were significantly lower at post-intervention and follow-up compared to pre-intervention. Happiness scores were significantly higher at post-intervention and follow-up compared to pre-intervention. There were no significant differences between post-intervention and follow-up, indicating maintenance of treatment gains.Conclusions: To the authors' knowledge, this is the first study to report an evaluation of an online therapy program utilising a peer developed and facilitated psychological intervention with a veteran population. Findings demonstrated a positive trend, indicating the Post War: Survive to Thrive Online Program may be beneficial for veterans; however, a controlled trial with a larger sample is required to determine effectiveness of the program

The impact of school connectedness on violent behavior, transport risk-taking behavior, and associated injuries in adolescence

Adolescents engage in many risk-taking behaviors that have the potential to lead to injury. The school environment has a significant role in shaping adolescent behavior, and this study aimed to provide additional information about the benefits associated with connectedness to school. Early adolescents aged 13 to 15 years (N = 509,49% boys) were surveyed about school connectedness, engagement in transport and violence risk-taking, and injury experiences. Significant relations were found between school connectedness and reduced engagement in both transport and violence risk-taking, as well as fewer associated injuries. This study has implications for the area of risk-taking and injury prevention, as it suggests the potential for reducing adolescents' injury through school based interventions targeting school connectedness.

Increased risk of attempted suicide in Australian veterans is associated with total and permanent incapacitation, unemployment and posttraumatic stress disorder severity

Military veterans have higher rates of suicidality and completed suicides compared to the general population. Previous research has demonstrated suicidal behaviour is higher in US combat veterans who are younger, suffer from posttraumatic stress disorder, depression and anxiety and score lower on measures of health. However, research on predictors of suicide for Australian veterans is limited. The aim of this study was to identify significant demographic and psychological differences between veterans with posttraumatic stress disorder who had attempted suicide and those with posttraumatic stress disorder who had not, as well as determine predictors of suicide attempts within an Australian cohort.A retrospective analysis was conducted on 229 ex-service personnel diagnosed with posttraumatic stress disorder who had attended a Military Service Trauma Recovery Day Program as outpatients at Toowong Private Hospital from 2007 to 2014. Patients completed a battery of mental health self-report questionnaires assessing symptoms of posttraumatic stress disorder, alcohol use, anger, depression, anxiety and quality of life. Demographic information and self-reported history of suicide attempts were also recorded.Results indicated the average age was significantly lower, and the rates of posttraumatic stress disorder, anger, anxiety and depression symptoms were significantly higher in those veterans with history of a suicide attempt. Multivariate logistic regression analyses indicated posttraumatic stress disorder symptom severity, unemployment or total and permanent incapacity pension status significantly predicted suicide attempt history.Among a cohort of Australian veterans with posttraumatic stress disorder, psychopathology severity, unemployment and total and permanent incapacity status are significantly associated with suicidality. This study highlights the importance of early identification of posttraumatic stress disorder and psychopathology, therapeutic and social engagement, and prioritisation of tangible employment options or meaningful and goal-directed activities for veterans deemed unable to work

Factor structure of posttraumatic stress disorder (PTSD) in Australian Vietnam Veterans: Confirmatory factor analysis of the Clinician-Administered PTSD Scale for DSM–5

Introduction: The Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM–5) brought a change to the symptom clusters of posttraumatic stress disorder (PTSD). In line with the DSM–5 changes, an updated version of the Clinician-Administered PTSD Scale (CAPS–5) was released. The CAPS–5 is considered to be the gold-standard measure of PTSD; however, examinations of the psychometric properties and optimal factor structure of this scale are underrepresented in PTSD studies. Methods: This study used confirmatory factor analysis (CFA) to assess the factor structure of the CAPS–5 using a sample of 267 male Australian Vietnam Veterans. Models drawn from the PTSD CFA literature were used to test the underlying dimensions of PTSD: the four-factor DSM–5 model, six-factor externalizing behaviour and anhedonia models, and seven-factor hybrid model. Results: The results found that the DSM–5 model showed slightly less than adequate fit (comparative fit index [CFI] = 0.90, Tucker–Lewis index [TLI] = 0.88, root mean square error of approximation [RMSEA] = 0.064), however, other models showed acceptable fit. The anhedonia model provided a significantly better fit than the other models (CFI = 0.92, TLI = 0.90, RMSEA = 0.059). Discussion: Overall, the results supported the anhedonia model. This result may indicate that the underlying dimensions of PTSD in Australian Vietnam Veterans may best be represented by six distinct factors.</p

Resilience and psychopathology in trauma-exposed Australian Veterans: An exploratory factor analysis of the Connor-Davidson Resilience Scale

Introduction: Resilience refers to the ability to cope with and adapt to significant adversity. It is a vital psychological construct among military personnel, who are often exposed to multiple stressors. The Connor-Davidson Resilience Scale (CD-RISC) is one of the most widely used resilience scales; however, the factor structure is inconsistent when used with military populations and has not been assessed in an Australian military population. The aim of this study was to explore the factor structure of the CD-RISC and investigate the relationship between resilience and psychopathology in an Australian Veteran sample. Methods: Australian trauma-exposed Veterans (N = 265) completed the CD-RISC, along with the Clinician-Administered PTSD Scale for DSM-5 and the Depression, Anxiety and Stress Scale-21. Exploratory factor analysis methods were used to explore the factor structure of the CD-RISC. Correlations and regression analyses were performed to investigate the relationship between resilience and psychological health. Results: A four-factor solution was proposed after removal of four poorly performing items. These factors were Self-Efficacy, Adaptability, Determination, and Tolerance of Negative Affect. The revised 21-item CD-RISC demonstrated excellent internal consistency, and regression analyses revealed a negative relationship between resilience factor scores and psychopathology. Compared with other resilience factors, Self-Efficacy contributed the largest proportion of unique variance to posttraumatic stress disorder, depression, and stress symptoms. Discussion: These findings provide preliminary support for the use of the revised 21-item CD-RISC as a reliable and valid measure of resilience in an Australian Veteran population, and highlight the potential benefit of cultivating self-efficacy in targeted resilience-building programs.</p

Sleep disturbances in australian Vietnam veterans with and without posttraumatic stress disorder

Study Objectives: Posttraumatic stress disorder (PTSD) is a condition that may develop after a traumatic event, particularly combat-related trauma. Although sleep disturbance is a hallmark of PTSD, the prevalence of sleep disturbances in Australian veterans with PTSD remains uncertain. This study aimed to subjectively compare the prevalence of sleep disturbances in Australian Vietnam veterans with and without PTSD. Methods: A cross-sectional cohort study compared trauma-exposed Australian Vietnam veterans with and without PTSD. PTSD diagnosis was confrmed using the Clinician Administered PTSD Scale for DSM-5. Sleep information was evaluated using supervised structured questionnaires, including Epworth Sleepiness Scale (ESS) and Berlin and Mayo Questionnaires. Results: Two hundred fourteen male Vietnam veterans (108 with PTSD) were included. Participants with PTSD had higher body mass index (30.3 versus 29 kg/m; P < .05), higher ESS score (9.2 versus 7.6; P < .05), and increased alcohol or medication use to assist with sleep (19% versus 6%; P < .01; and 44% versus 14%; P < .01). Those with PTSD were less likely to sleep well (32% versus 72%; P < .01) and reported higher rates of restless legs (45% versus 25%; P < .01), nightmares (91% versus 29%; P < .01), nocturnal screaming (73% versus 18%; P < .01), sleep terrors (61% versus 13%; P < .01) and dream enactment (78% versus 11.8%; P < .01). The PTSD group had higher rates of diagnosed OSA (42% versus 21%; P < .01) and an increased risk of OSA on the Berlin Questionnaire (69% versus 43%; P < .01). Conclusions: Compared to trauma-exposed controls, Australian Vietnam veterans with PTSD demonstrated an increased prevalence of a wide range of sleep disturbances, including OSA. In veterans with PTSD, detailed sleep assessment, including consideration of polysomnography, is paramount

Detailed polysomnography in Australian Vietnam veterans with and without posttraumatic stress disorder

Study Objectives Recent results from the PTSD Initiative, a cross-sectional cohort study in Australian Vietnam veterans (VV) with and without posttraumatic stress disorder (PTSD), demonstrated an increased prevalence of self-reported sleep disturbances in those with PTSD. This study aimed to objectively assess the prevalence of sleep disorders in the same cohort using detailed polysomnography (PSG). Methods Participants from the PTSD Initiative were recruited to undergo PSG. PTSD status was determined with the Clinician Administered PTSD Scale for DSM-5 (CAPS-5). Subjective sleep information was attained via structured questionnaires. Data from single night PSG were compared between trauma-exposed VV with and without PTSD. Results A total of 74 trauma-exposed male VV (40 with PTSD) underwent PSG (prospective n = 59, retrospective n = 15). All PSG parameters were similar between groups. No difference was seen in PSG-diagnosed obstructive sleep apnea (OSA) or periodic limb movements of sleep (PLMS). VV with PTSD showed a trend toward increased duration of sleep with oxygen saturations < 90% (10% versus 1.8%; P = .07). VV with PTSD reported increased sleep onset latency (42.4 versus 13.3 minutes; P < .01); were less likely to report sleeping well (32.5% versus 67.5%; P < .01); had higher OSA risk using Berlin Questionnaire (BQ) (70% versus 38.2%; P < .01); and had higher rates of partner-reported limb movements (56.4% versus 17.6%; P < .01). No association between PSG-diagnosed OSA and PTSD severity was evident. Conclusions In Australian VV with and without PTSD, no difference was seen across all PSG parameters including the diagnosis and severity of OSA and PLMS. However, VV with PTSD demonstrated an increased perception of sleep disturbances
