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.

Background A concerning proportion of former Australian Defence Force (ADF) members meet criteria for a mental health condition. Mental health difficulties not only affect the individual veteran. They have been found to negatively impact the mental health of family, with an increased likelihood for family members of veterans developing a mental health condition. The aim of this study was to evaluate whether participating in a Mental Health First Aid (MHFA) program improved family members of veterans mental health knowledge, reduced personal and perceived mental health stigma, reduced social distancing attitudes and increased confidence and willingness to engage in MHFA helping behaviours. Additionally, the study measured participant’s general mental health and levels of burnout. Method The study utilised an uncontrolled design with assessment at three time points (baseline, post-program and three-month follow-up). Participants (N = 57) were immediate and extended family members of former ADF members with a mental health condition, who took part in a two-day standard adult MHFA program. At each time point, participants completed self-report measures assessing mental health knowledge, personal and perceived mental health stigma, social distancing attitudes, confidence and willingness to engage in MHFA helping behaviours, general mental health and burnout. Cochranes Q and repeated measures ANOVA was computed to measure the impact of time on the outcome variables. Results Results indicated significant improvements in MHFA knowledge and confidence in providing MHFA assistance. Significant reductions in personal mental health stigma (i.e. an individual’s attitude towards mental health) for schizophrenia were observed and maintained at follow up. High levels of perceived mental health stigma (i.e. the belief an individual holds about others attitudes towards mental health) were reported with no significant changes observed following the MHFA program. Results did not indicate any significant benefit in improving general psychological distress or burnout at follow up. The participant sample had high levels of mental health difficulties with over half reporting a lifetime mental health diagnosis. Conclusion The study is an important contribution to the international literature on MHFA. The provision of a MHFA program to family members of military veterans has not previously been evaluated. Implications of the findings are discussed with regards to future directions of MHFA research and implementing MHFA programs in this population.

Background Posttraumatic stress disorder (PTSD) has been associated with volumetric and white matter microstructural changes among general and veteran populations. However, regions implicated have greatly varied and often conflict between studies, potentially due to confounding comorbidities within samples. This study compared grey matter volume and white matter microstructure among Australian combat veterans with and without a lifetime diagnosis of PTSD, in a homogenous sample assessed for known confounding comorbidities. Methods Sixty-eight male trauma-exposed veterans (16 PTSD-diagnosed; mean age 69 years) completed a battery of psychometric assessments and underwent magnetic resonance and diffusion tensor imaging. Analyses included tract-based spatial statistics, voxel-wise analyses, diffusion connectome-based group-wise analysis, and volumetric analysis. Results Significantly smaller grey matter volumes were observed in the left prefrontal cortex ( P = 0.026), bilateral middle frontal gyrus ( P = 0.021), and left anterior insula ( P = 0.048) in the PTSD group compared to controls. Significant negative correlations were found between PTSD symptom severity and fractional anisotropy values in the left corticospinal tract ( R 2 = 0.34, P = 0.024) and left inferior cerebellar peduncle ( R 2 = 0.62, P = 0.016). No connectome-based differences in white matter properties were observed. Conclusions Findings from this study reinforce reports of white matter alterations, as indicated by reduced fractional anisotropy values, in relation to PTSD symptom severity, as well as patterns of reduced volume in the prefrontal cortex. These results contribute to the developing profile of neuroanatomical differences uniquely attributable to veterans who suffer from chronic PTSD.

ObjectivesPosttraumatic stress disorder (PTSD) is associated with sleep disturbances including insomnia and nightmares. This study compared cognitive behavioral therapy for insomnia (CBT‐I) with CBT‐I combined with imagery rehearsal therapy (IRT) for nightmares to evaluate if the combined treatment led to greater reductions in trauma‐related sleep disturbances in Australian veterans.MethodsVeterans with diagnosed PTSD, high insomnia symptom severity, and nightmares (N = 31) were randomized to eight group CBT‐I sessions or eight group CBT‐I + IRT sessions. Self‐reported sleep, nightmare, and psychological measures (primary outcome: Pittsburgh Sleep Quality Index), and objective actigraphy data were collected; the effect of obstructive sleep apnea (OSA) risk on treatment outcomes was also examined.ResultsNo treatment condition effects were detected for the combined treatment compared to CBT‐I alone, and no moderating effect of OSA risk was detected. On average, participants from both groups improved on various self‐report measures over time (baseline to 3 months posttreatment). Despite the improvements, mean scores for sleep‐specific measures remained indicative of poor sleep quality. There were also no significant differences between the groups on the actigraphy indices.ConclusionsThe findings indicate that there is potential to optimize both treatments for veterans with trauma‐related sleep disturbances.
