This study explored implications of the emotion self-confidence model of suicidal ideation (ESC-SI Model; Deeley & Love, 2012 ) in adolescents. Referencing stress-coping principles, the model implies that high levels of negative emotionality coupled with low expectations for coping with, or changing, this experience (low emotion self-confidence) would predispose towards thoughts of suicide. The hypothesis was examined in 136 community adolescents using questionnaire methodology in a cross-sectional, correlational design. Regression analysis showed the model of best fit was a direct-effects (cumulative) model in which negative emotionality and emotion self-confidence each contributed to suicidal ideation through both shared and unique variance. Results supported the ESC-SI Model's validity, though its generalizability will only be confirmed through replication and further empirical research.
