106. Experiential Avoidance and Suicidality in Outpatients with Emotional Disorders: A Latent Profile Analysis

Experiential avoidance (EA) is defined as the tendency to avoid negative internal experiences. Previous analysis identified four subgroups of EA based on the six subscales of the Multidimensional Experiential Avoidance Questionnaire (MEAQ) and that the group membership correlated with depression. The current study aimed to explore whether the latent profiles (LP) of EA are correlated with suicidality. The study used data from a clinical trial at the Center for Anxiety and Related Disorders at Boston University, including outpatients with heterogeneous anxiety and co-occurring depressive disorders (N = 223). EA was assessed using the MEAQ. Suicidality was assessed and quantified based on thoughts, ideations, attempts, plans, and severity. LP analysis with categorical and continuous auxiliary variables was conducted. Suicidality variables were regressed on the previously identified class membership to evaluate the associations between EA groups and suicidality. The results indicated that LP of EA are associated with different facets and severity of suicidality in patients with emotional disorders. High DA, RD, and low DE together are associated with higher suicidality. Analysis with larger samples in diverse populations and using additional measures of suicidality is an important future direction.
