The aims of the study are to examine the predictive role of fluctuations in daily life mood, social contexts, and behavior on subsequent suicidal ideation (SI); and to identify clinical and psychological factors associated with the general frequency of SI in a high-risk sample. The sample comprised 42 adults (73.8% female) hospitalized for a suicide attempt. Immediately following hospital discharge, they used Ecological Momentary Assessment for seven consecutive days, providing repeated measures of SI, environmental, contextual, and behavioral factors. Controlling for prior SI, a number of contextual variables were associated with subsequent SI. Being at home or at work were both associated with an increased probability of SI, while being in the home of close others, or in a festive or leisure environment decreased SI probability. Working, passive leisure and inactivity all increased the likelihood of SI. Being alone increased SI while being with close others significantly reduced this risk. Finally, no overall effect for stressful events was found but negative family events specifically were associated with increased likelihood of SI (γ = 0.448, t = 2.255, df = 29, p < 0.05). The findings provide preliminary results regarding proximal environmental and behavioral factors associated with the occurrence of suicidal ideation in a high-risk sample.
