ABSTRACT
Objective: Posttraumatic stress disorder (PTSD) is one of the most frequently treated behavioral health conditions within the Department of Veterans Affairs and often co-occurs with alcohol or substance use. Past research suggests that alcohol and/or substance use may be used to cope with PTSD symptoms but there are inconsistent findings in how specific PTSD symptom clusters are associated with alcohol use disorder (AUD) or substance use disorder (SUD). Evaluating the relationship between PTSD symptom clusters and craving for individual drug of dependence may help explain these ambiguous results. Methods: Veterans (N = 167) recently engaged in mental health residential treatment were recruited to participate in a semi-structured diagnostic interview (Structured Clinical Interview for the DSM-5, Research Version [SCID-5-RV]) to assess for past 12-month history of AUD/SUD. Participants also completed the Posttraumatic Stress Disorder Checklist for DSM-5 (PCL-5) to assess PTSD symptoms. Results: Covarying for severity of alcohol use, avoidance symptoms were significantly associated with alcohol craving for veterans with alcohol as their drug of dependence. Covarying for severity of stimulant use, no PTSD symptom clusters were associated with stimulant craving for veterans with stimulants as their drug of dependence. Conclusions: Veterans with high levels of PTSD avoidance symptoms may experience alcohol craving symptoms because they believe that alcohol use will eliminate or alleviate thoughts, feelings, or external reminders of the trauma. These results have important clinical implications in the treatment of co-occurring PTSD and AUD.

The current retrospective, longitudinal study applied Andersen's Behavioral Model of Health Services Use to examine how demographic characteristics (age), available resources (e.g., a caregiver, the Mobile Veterans Program [MVP]) and health needs (e.g., cognitive and physical functioning, depressive symptoms) affect hospitalization and institutionalization outcomes among older adults using the MVP. Fifty-four Veterans (age 55 to 95) participating in the MVP for up to 2 years were examined using hierarchical linear modeling (HLM) and growth curve model. In the final HLM model, each 1-point increase in depressive symptoms was associated with 76% (p ≤ 0.05) greater risk of institutionalization and 40% (p ≤ 0.01) greater risk of hospitalization. Each 1-point increase in cognitive functioning was associated with 24% (p ≤ 0.05) lower risk of institutionalization. The relationship between caregiver burden and hospitalization was attenuated by frequency of MVP visits. Services focused on reducing depressive symptoms may influence health service use and reduce caregiver burden in this population. [Journal of Gerontological Nursing, 46(5), 15-22.].
