Defeat, Entrapment, and Positive Future Thinking: Examining Key Theoretical Predictors of Suicidal Ideation Among Adolescents

open access: yesFrontiers in Psychology, 2021
Adult-based suicide theories have determined much of what we know about suicidal ideation. Here, we investigate the extent to which elements of the Integrated Motivational-Volitional (IMV) model generalize to adolescence, a period when rates of suicidal ...
