Testing Models Relating Rejection, Depression, Interpersonal Needs, and Psychache to Suicide Risk in Nonclinical Individuals

Using structural equation modeling, we tested a primary model of suicide risk and 3 competing, alternative models based on 4 psychological variables deemed important in the literature (perception of parental rejection, depression, interpersonal needs comprising perceived burdensomeness and thwarted belongingness, and psychache), in a nonclinical sample of Portuguese adults.A convenience sample of 203 adults (100 men, 103 women; aged 18-65 years) participated in this study.Analyses demonstrated that the proposed primary model had the best fit to the observed data. The differences in fit indexes for this model and one of the alternative models, however, were not substantial.Perceived parental rejection related directly to suicide risk and indirectly via depression and interpersonal needs. Depression linked indirectly to suicide risk via interpersonal needs and psychache. Interpersonal needs related directly to suicide risk and indirectly via psychache, which related directly to suicide risk.
