A powerful safety net: Social support moderates the association of quality of life deficits with suicidal ideation in long-term childhood cancer survivors.

AbstractObjectivesResearch approachFindingsConclusionCancer survivors are at risk for suicidality. We aimed to expand the knowledge about protective factors and their interplay with risk factors by testing social support as a modifier of the association of Quality of Life (QoL) deficits with suicidal ideation.We surveyed <italic>N</italic> = 633 childhood cancer survivors (CCS) using validated questionnaires (EORTC Core Quality of Life questionnaire QLQ-C30, Patient Health Questionnaire PHQ-9). The interaction of QoL and social support was investigated using multiple linear regression analysis.CCS reporting suicide attempts and current suicidal ideation (SI) had lower QoL. CCS with SI reported less social support. QoL and social support were independently associated with SI and interacted: among CCS with less social support, low QoL was more strongly associated with SI.The results highlight the need for interdisciplinary survivorship care, and to focus on risk and protective factors to strengthen suicide prevention.
