Understanding Compliance Rates in Suicide Research During the Post-Discharge Period.

Abstract

Introduction: The period following discharge from psychiatric hospitalization is one of particularly elevated suicide risk. It is essential to better understand risk factors for suicide during this period; however, retention and compliance in longitudinal research can be a challenge with high-risk populations.

Methods: We examined compliance rates in the six-month period following psychiatric hospital discharge among 174 adults (149 psychiatric patients and 25 healthy controls) across three data collection methods: ecological momentary assessment (EMA), weekly clinical assessment phone calls, and clinical follow-up assessments at two- and six-months post-discharge. We examined whether clinical and demographic characteristics influenced compliance rates.

Results: Results suggested low rates of EMA compliance, but strong rates of completion of weekly phone calls and follow-up assessments. Compared to psychiatric patients, healthy controls completed more EMA and weekly phone calls, but not follow-up assessments. Participants who met current diagnostic criteria for a major depressive episode and who scored above the clinical threshold for borderline personality disorder symptoms had lower EMA compliance rates.

Conclusions: These findings have important implications for strategies to improve patient engagement in research during this high-risk period.
