Abstrakt: Aims: The interpersonal theory of suicide (ITPS) provides a theoretical model for suicidal behaviour. It includes two interpersonal variables, thwarted belongingness (TB) and perceived burdensomeness (PB). This study tested the relationship between ITPS interpersonal variables and suicide risk (presence/absence of suicidal ideation and suicide attempts throughout life) in a clinical sample of Spanish adolescents. We also assessed the potential mediation effect of these variables in the well-established relationship between stressful life events (SLE) and suicide risk.
Methods: We recruited 147 adolescents aged 11-17 from the Child and Adolescent Mental Health Outpatient Services of the Jiménez Díaz Foundation (Madrid, Spain). Different questionnaires were administered to assess suicidal behaviour and SLE (SITBI, The Stressful Life Events Scale) and to calculate proxy measures for ITPS interpersonal factors (SDQ, STAXI-NA, CDI).
Results: TB and PB significantly correlated with suicide risk. PB played a mediating role in the relationship between SLE and suicide risk: adolescents reporting SLE were more likely to enact suicide behaviours when they experienced higher PB. Patients scoring higher PB were more likely to receive more intense treatment but tended to abandon intervention promptly.
Conclusions: ITPS seems useful for predicting suicide risk in an adolescent clinical sample. The results suggest an important role for PB in the SLE-suicide risk relationship and may impact the treatment process. Our exploratory findings should be addressed in future studies.
