This study is Phase 3 of Project SERVE (Study Evaluating Returning Veterans' Experiences). Through two prior phases, SERVE has followed a cohort of post-9/11 Veterans since 2010 and has identified numerous risk and protective factors. SERVE's overall objective is to understand and improve the long-term functional outcomes of post-9/11 Veterans. Consistent with the investigators' conceptual model, the central hypothesis is that psychological flexibility and other trans-diagnostic treatment targets mediate the effects of the most common mental and physical wounds of war on long-term functioning and self-directed violence (i.e., suicide risk). Thus, integrated interventions specifically designed to improve functioning associated with these conditions are most likely to promote long-term recovery among the most impaired Veterans. The investigators will test the central hypothesis and accomplish the overall objective by pursuing the following specific aims: Aim 1: Identify treatment targets that prospectively predict functional disability, family functioning and self-directed violence (SDV) in post-9/11 Veterans with PTSD, depression, chronic pain, TBI, and/or AUD. To achieve this aim, the investigators will follow 500 Veterans for 2 years in order to prospectively evaluate the impact of several novel, treatment-relevant factors on functional disability and SDV over time. H1: Novel factors (mindfulness, perceived burdensomeness, thwarted belongingness, and moral injury) along with established treatment targets (psychological flexibility, self-compassion, and emotion regulation) will prospectively predict functional disability and SDV after accounting for covariates.
Research by the investigators' team and others demonstrates that posttraumatic stress disorder (PTSD), depression, alcohol use disorders (AUD), traumatic brain injury (TBI), and chronic pain frequently co-occur among post-9/11 war Veterans and are associated with functional impairment and suicide risk; however, no treatment currently exists that has been specifically designed to promote functional recovery among Veterans experiencing any combination of these most common mental and physical wounds of war. The investigative team has: (A) identified multiple modifiable psychosocial factors (emotion regulation, psychological flexibility, self-compassion) that prospectively predict impairment and suicidal ideation in Veterans; (B) characterized long-term trajectories of resilience and functional disability in Veterans; (C) determined that high utilization of VA mental health services appears to have little, if any, impact on the functional recovery of Veterans on the moderate and severely impaired trajectories; (D) identified psychological flexibility (i.e., the ability to remain present in the moment despite emotional distress and to persist in changing behavior in the pursuit of one's values and goals) as a unique, prospective predictor of membership in the severely impaired functional trajectory and of suicidal ideation, even after accounting for the effects of co-morbidity; and (E) demonstrated that Acceptance and Commitment Therapy (ACT)-a trans-diagnostic, mindfulness-based behavior therapy that seeks to improve functioning by targeting psychological flexibility -can lead to recovery, including sustained improvements in functional disability, quality of life (QoL), suicidal ideation, PTSD, and AUD symptoms among severely impaired Veterans with co-occurring PTSD-AUD.

Columbia Suicide Scale
The Columbia Suicide Severity Rating Scale (C-SSRS; Posner et al., 2008) is a state-of-the-art suicide assessment for individuals perceived to be at high risk for suicidality. Internal consistency ranged from .73 to .95 (Posner et al., 2011). Values on the intensity of suicidal ideation (e.g., frequency, duration, controllability, deterrents, reasons for ideation) are summed to create a total score; range from 0 to 25, where higher scores indicate higher SI severity.
Time frame: Baseline and 24-month
World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0)
Self-report assessment of functional disability with total score and 6 domains of functioning: understanding and communicating, mobility, getting along with others, life activities (i.e., work, education, household responsibilities), participation in society, and self-care (Ustun et al., 2010). Both global and specific areas of functioning are crucial in thoroughly understanding functional recovery, as Veterans may function well in one area and have difficulty in another. Moreover, some domains may be affected by contextual factors instead of representing functional capacity (e.g., work functioning in a struggling economy independent of impairment). Means on this measure capture items from all domain subscales and can range from 0 to 3 where higher scores indicate higher levels of disability.
Time frame: Baseline, 8-month, 16-month, and 24-month
Clinician Administered NSSI Disorder Index (CANDI)
The Clinician Administered NSSI Disorder Index (CANDI) is a clinical interview that diagnoses Nonsuicidal Self Injury (NSSI) disorder and type and frequency of NSSI. Demonstrated good reliability and validity in prior research. Results report the number of participants that meet for a diagnosis of NSSID.
Time frame: Baseline and 24-month
Inventory of Psychosocial Functioning (IPF) - Brief
Self-report measure (Marx et al., 2009; Bovin et al., 2018) of problems in different domains of life (e.g., Romantic Relationships with a Spouse/Partner, Family, Work, Friendships and Socializing, Parenting, Education, and Self-Care). The short version has a .90 correlation with the full 80-item instrument (Co-I Marx, personal communication). Adjusted totals range from 0 to 100 with higher scores indicate greater functional impairment.
Time frame: Baseline, 8-month, 16-month, and 24-month
Beck Scale for Suicide Ideation (BSSI)
Widely-used self-report measure of intensity of thoughts and behaviors associated with suicide. Includes 2 additional items that ask about past suicide attempts as well as the level of suicidal intent during the most recent attempt. Prior research shows that endorsement of suicidal thoughts and behaviors can be greater on self-report questionnaires compared to interviews. Total scores range from 0 to 42 where higher scores indicate higher suicidal ideation.
Time frame: Baseline and 24-month
Quality of Life Scale
Self-report (Burkhardt, et al., 1989) assessing how satisfied people are in different areas of their life, distinct from health status, (e.g., mate, physical well-being, relationships with others, social, community, and civic activities, personal development and fulfillment, recreation, and independence). Good internal consistency and high test-retest reliability (Burckhardt et al. 2003). Total scores range from 16 to 112 with higher scores indicating greater life satisfaction.
Time frame: Baseline, 8-month, 16-month, and 24-month
