TY - JOUR PY - 2021// TI - An investigation into the bidirectional relationship between post-traumatic stress disorder and suicidal ideation: a nine year study JO - Journal of anxiety disorders A1 - Schafer, Katherine Musacchio A1 - Clancy, Kevin J. A1 - Joiner, Thomas SP - e102510 EP - e102510 VL - 85 IS - N2 - Suicide is the second leading cause of death in adolescents; a frequent precursor of suicide is suicidal ideation (SI). Literature indicates that Post-Traumatic Stress Disorder (PTSD) and SI are robust cross-sectional correlates of one another, with PTSD often being conceptualized as a risk factor (i.e., conferring risk) for SI. Indeed, PTSD is a well-established risk factor for SI; however, SI is an understudied risk factor for PTSD. It is possible that, yet unknown if, PTSD and SI promote each other over time in a bidirectional fashion. We investigated the bidirectional longitudinal associations between PTSD and SI in a large, diverse sample, who at baseline were adolescents. Participants were interviewed between 1995 and 1998 and again between 2004 and 2008. We hypothesized that PTSD and SI would be cross-sectionally, longitudinally, and bidirectionally related and that the number of traumas endorsed at baseline would be positively associated with PTSD and SI at baseline and follow-up. Indeed, PTSD and SI were cross-sectionally correlated at baseline, but not follow-up. PTSD predicted SI over nine years; however, SI during adolescence did not predict PTSD in adulthood. Finally, poly-trauma endorsed at baseline was associated with increased risk of SI, but not PTSD, over nine years.
