Ecological momentary assessment (EMA) can capture short-term fluctuations in suicidal thoughts and related processes that are obscured by traditional pre-post assessments, but sustained intensive sampling may impose substantial participant burden. Measurement-burst designs address this tradeoff by repeating brief periods of intensive assessment across longer timescales. We piloted a repeated EMA block design consisting of one week of EMA per month across three months within a Caring Contacts intervention study. The current pilot study included 30 participants receiving outpatient mental health services; all received Caring Contacts and completed EMA for one/month over 3 months with items focused on variability in suicide outcomes (desire to live, desire to die, suicide urges) and mechanisms through which caring contacts could impact these outcomes (perceived burdensomeness, entrapment, mattering, social & personal responsibility), and a qualitative interview. Results provide support for the feasibility and acceptability of utilizing EMA in the context of Caring Contacts delivery and provide initial support for the use of EMA to capture dynamic mechanisms of suicide outcomes. Repeated EMA blocks offer a promising approach for examining suicide-related processes across timescales longer than those typically captured by a single period of intensive sampling while limiting the burden of continuous EMA. Larger studies are needed to determine whether repeated EMA blocks provide meaningful advantages over less intensive assessment schedules for detecting change in suicide-related mechanisms and outcomes.
