Posttraumatic Stress Disorder and Suicidal Ideation : The Moderating Effect of Posttraumatic Cognitions
© 2020 International Society for Traumatic Stress Studies..
Although individuals with posttraumatic stress disorder (PTSD) are at an increased risk for suicidal ideation (SI), it is unclear what factors might influence this association. Investigators have hypothesized that posttraumatic cognitions (PTCs), such as self-blame (SB) or negative cognitions about the self (NCAS) or world (NCAW), would play a role, but this has not been investigated empirically. Accordingly, we evaluated a model in which the association between PTSD symptoms and SI was moderated by PTCs in a sample of trauma-exposed undergraduate students (N = 410). To identify the specific source of this hypothesized moderation effect, we ran the moderation model separately for PTSD total severity, PTSD total severity without the cognition-related items, and each of four DSM PTSD symptom clusters in combination with each of three types of PTCs (i.e., NCAS, NCAW, SB), accounting for quadratic effects. The results revealed that NCAW moderated the positive association between all six of the PTSD variables and SI, f2 s < .01 to .04. Analyses of simple slopes generally revealed strong positive associations between PTSD symptoms with SI at high levels of NCAW, no associations at moderate levels, and negative associations at low levels. We also found one statistically significant quadratic effect when examining avoidance and NCAW. In contrast, neither NCAS nor SB emerged as a significant moderator in any of our regression models. These findings highlight the importance of addressing PTCs-particularly NCAW-in trauma survivors.
