Psychometric properties of the self-injurious thoughts and behaviors interview–short form among U.S. active duty military Service members and Veterans
Abstract: We assessed the interrater reliability, convergent validity, and discriminant validity of the Self-Injurious Thoughts and Behaviors Interview-Short Form (SITBI-SF) in a sample of 1,944 active duty service members and veterans seeking services for posttraumatic stress disorder (PTSD) and related conditions. The SITBI-SF demonstrated high interrater reliability and good convergent and discriminant validity. The measurement properties of the SITBI-SF were comparable across service members and veterans. Approximately 8% of participants who denied a history of suicidal ideation on the SITBI-SF reported suicidal ideation on a separate self-report questionnaire (i.e., discordant responders). Discordant responders reported significantly higher levels of PTSD symptoms than those who denied suicidal ideation on both response formats. Findings suggest that the SITBI-SF is a reliable and valid interview-based measure of suicide-related thoughts and behaviors for use with military service members and veterans. Suicide risk assessment might be optimized if the SITBI-SF interview is combined with a self-report measure of related constructs.
Abstract: Objectives: Increasing numbers of older adults are reentering community following incarceration (i.e., reentry), yet risk of incident neurodegenerative disorders associated with reentry is unknown. Our objective was to determine association between reentry status (reentry vs never-incarcerated) and mild cognitive impairment (MCI) and/or dementia. Methods: This nationwide, longitudinal cohort study used linked Centers for Medicare & Medicaid Services and Veterans Health Administration data. Participants were aged 65 years or older who experienced reentry between October 1, 2012, and December 31, 2018, with no preincarceration MCI/dementia, compared with age-matched/sex-matched never-incarcerated veterans. MCI/dementia was defined by diagnostic codes. Fine-Gray proportional hazards models were used to examine association. Results: This study included 35,520 veterans, mean age of 70 years, and approximately 1% women. The reentry group (N = 5,920) had higher incidence of MCI/dementia compared with the never-incarcerated group (N = 29,600; 10.2% vs 7.2%; fully adjusted hazard ratio [aHR] 1.12; 95% CI 1.00-1.25). On further investigation, reentry was associated with increased risk of dementia with or without prior MCI diagnosis (aHR 1.21; 95% CI 1.06-1.39) but not MCI only. Discussion: Transition from incarceration to community increased risk of neurocognitive diagnosis. Findings indicate health/social services to identify and address significant cognitive deficits on late-life reentry. Limitations include generalizability to nonveterans.
