Associations between mindfulness, posttraumatic stress disorder symptoms, and posttraumatic growth in police academy cadets: An exploratory study.

Mindfulness-based treatments have been increasingly noted in the professional literature as a possible means to reduce posttraumatic stress disorder (PTSD) symptoms and promote well-being, especially among law enforcement officers. Scant research, however, has been conducted to study dispositional mindfulness and health outcomes in police cadets. The current exploratory study examined the association between the various facets of dispositional mindfulness (i.e., observing, describing, acting with awareness, nonjudging, and nonreactivity) and PTSD symptoms, posttraumatic growth (PTG), and other variables, including world assumptions, in police cadets (N = 379). Consistent with findings from previous studies of experienced officers, the results indicate that (a) mindful nonjudging is a salient trait in police cadets, which uniquely predicted lower PTSD symptoms, ß = -.31, p < .001, and was related to lower levels of PTG, r = -.12, p = .025, and (b) mindful observing was related to higher levels of PTSD symptoms, r = .14, p = .009 and higher levels of PTG, r = .26, p < .001, in the present sample. In addition, the findings demonstrate that nonjudging is an important trait in police cadets regarding world assumptions such that nonjudging was a significant, unique predictor of world assumption facets, including controllability of events, ß = .15, p = .025, and trustworthiness and goodness of people, ß = .18, p = .004. Clinical implications, including the importance of understanding the association between mindful nonjudging and the shattering and rebuilding of worldviews and following trauma reactions, are discussed.

Genetic and Psychosocial Risk Factors Associated with Suicide Among Community Veterans: Implications for Screening, Treatment and Precision Medicine.

INTRODUCTION: Since veteran suicide is a concern and our knowledge of predictive factors is still limited, our objective was to assess risk factors for suicide, including genetic factors, among deployed veterans. METHODS: For this study, we surveyed 1730 veterans who were outpatients in a multi-hospital system in Pennsylvania. Altogether, 1041 veterans (60%) provided a DNA sample. The genetic risk variants investigated were within loci previously associated with PTSD and substance misuse, including CRHR1, CHRNA5, RORA, and FKBP5 genetic variations, which were used to calculate a polygenic risk score (range=0-8, mean=3.6, SD=1.4). RESULTS: Most veterans (56.2%) were deployed to Vietnam while significant numbers were deployed to Iraq, Afghanistan, and other post-Vietnam conflicts. Overall, 95.1% of the veterans were male, their mean age was 56.2 (SD=12), and 95.6% were Caucasian. Among the veterans, 24% had high combat exposure. The prevalence of lifetime suicidal thoughts was 11.3%. Additionally, 5.7% ever developed a suicide plan or attempted suicide in their lifetimes. Among those with a history of a lifetime suicide attempt or suicide plan, the PTSD genetic risk score was significantly higher (OR=3.96 vs 3.55, p=0.033), but for suicidal thoughts, this association was not significant (p=0.717). In multivariable analysis (MVA) logistic regression, significant predictors of attempting suicide or having a suicide plan were history of depression (OR=5.04, p<0.001), PTSD genetic risk score (OR=1.25, p=0.036), history of childhood abuse/neglect (OR=2.24, p=0.009), and lifetime marijuana use (OR= 1.56, p=0.020). Conversely, rural residence was protective for suicide risk (OR=0.49; p=0.031). For suicidal thoughts, in the MVA genetic risk score was not significant (p=0.697), but history of child abuse/neglect (p<0.001), history of depression (p>0.001), low psychological resilience (p=0.004), and lifetime marijuana use (p=0.022) were significant. DISCUSSION: In this study, we identified genetic risk variants and other predictors for suicide among veterans that may have implications for future screening and clinical care. Further research is advised.
