Despite promising findings from problem-solving interventions in the treatment of parasuicide, little is known about problem-solving difficulties that distinguish “Non-Repeaters” from “Repeaters”. The present study examined whether problem-solving ability could be used to identify repeaters of parasuicide. Findings are presented from the follow-up part (N = 35) of a larger investigation (N = 146) of non-consecutive hospital-treated cases of parasuicide, interviewed by the National Suicide Research Foundation in Ireland as part of the WHO/EURO Multicentre Study on Suicidal Behaviour. The median interval from initial to follow-up interview was 15 months. The European Parasuicide Study Interview Schedule (EPSIS II) was used in the follow-up interview. Within this schedule, responses to a questionnaire measuring habitual problem-solving style were analysed. Repeaters scored significantly lower than non-repeaters on the following problem-solving dimensions: Active handling, Comforting cognitions and Seek social support. Repeaters scored significantly higher on the Passive reactions dimension. A logistic regression model including these four problem-solving dimensions correctly identified 79% of the repeaters and 82% of the non-repeaters. Despite the limitations of this sample size, these significant differences in problem solving have implications for the treatment of parasuicide. Further work, using larger samples, is required.
