Abstract
  • Adolescent self-injurious thoughts and behaviors (SITB) have been increasingly recognized as a major public health problem. Virtually absent from this literature are comprehensive, developmentally informed theoretical models which can account for the etiology and interrelationships among cognitive, social, and biological variables known to be associated with adolescent SITB. The present study preliminarily tested a biopsychosocial model of adolescent SITB which hypothesized that cognitive vulnerability and increased emotion reactivity in response to a laboratory social stress task would be related to greater engagement in SITB. Adolescent participants (n = 62; 73% female) completed measures of negative inferential style, past engagement in SITB, and participated in an in vivo speech task while samples of salivary cortisol were collected at regular intervals throughout the assessment. MANOVA and MANCOVA analyses and latent growth curve models provided inconclusive support for hypotheses and highlighted limitations related to the sample utilized in the present study. Several important directions for future research are discussed.
