Abstract
Better understanding of the determinants of suicidal distress may be critical to improving clinical approaches to suicide prevention. According to the Interpersonal-Psychological Theory of Suicide, perceived burdensomeness (PB) is one of the proximal, causal risk factors for the development of suicidal distress. Considerable cross-sectional data has supported this association, but limited longitudinal data has investigated whether short-term change in PB influences subsequent suicidal ideation (SI). This longitudinal study involved daily assessments of both PB and SI over a 7-day period in 791 Australian adults who reported recent or current SI. Eight different panel models, with and without covariates were fit to examine cross-lagged effects between PB and SI. In the final model, there was weak evidence for a lagged effect from PB on SI the next day (β = 0.175), although the contemporaneous effect of PB on SI was larger and more consistent (β = 0.948). There was little evidence for lagged effects of SI on PB (β = 0.008). Effects varied across age groups and living situations. Inconsistent with the theory, findings suggest limited value of PB in predicting later SI, after accounting for cross-sectional relationships. Greater consideration of other psychosocial and contextual risk factors may be important for theories of suicide risk and for supporting people who are at risk of suicidal behaviour.
期刊介绍:
Founded in 1961 to report on the latest work in psychiatry and cognate disciplines, the Journal of Psychiatric Research is dedicated to innovative and timely studies of four important areas of research:
(1) clinical studies of all disciplines relating to psychiatric illness, as well as normal human behaviour, including biochemical, physiological, genetic, environmental, social, psychological and epidemiological factors;
(2) basic studies pertaining to psychiatry in such fields as neuropsychopharmacology, neuroendocrinology, electrophysiology, genetics, experimental psychology and epidemiology;
(3) the growing application of clinical laboratory techniques in psychiatry, including imagery and spectroscopy of the brain, molecular biology and computer sciences;
