Basic need satisfaction and suicidal ideation: A self-determination perspective on interpersonal suicide risk and suicidal thinking.

This study investigated the relationship between the basic psychological needs, as outlined by self-determination theory, and the interpersonal predictors of suicidal desire, as outlined by the interpersonal-psychological theory of suicidal behavior. This study investigated the relationship between the basic psychological needs, as outlined by self-determination theory, and the interpersonal predictors of suicidal desire, as outlined by the interpersonal-psychological theory of suicidal behavior. It was hypothesized that basic need satisfaction (collective feeling of autonomy, relatedness, and competence) would be related to suicidal ideation through thwarted belongingness and perceived burdensomeness. Mediation analyses demonstrated that thwarted belongingness and perceived burdensomeness both individually mediated the relationship between basic need satisfaction and suicidal ideation.
