Abstract:
Background: Cognitive complaints (CCs) influence and mediate the impacts of affective temperaments and depressive symptoms on functional disability. Childhood maltreatment and trait anxiety also affect functional disability. However, whether CCs mediate the impact of childhood maltreatment and trait anxiety on functional disability, remains unknown. Objectives: To study the mediating effect of CCs between childhood maltreatment, trait anxiety, and functional disability. Methods: This cross-sectional study of 571 adults utilized the Child Abuse and Trauma Scale, State-trait Anxiety Inventory Form Y, Cognitive Complaints in Bipolar Disorder Rating Assessment, and Sheehan Disability Scale to evaluate childhood maltreatment, trait anxiety, CCs, and functional disability, respectively. We examined the mediating effects of CCs on childhood maltreatment, trait anxiety, and functional disability using structural equation modeling and mediation analysis. Results: The results showed that CCs mediated the impact of trait anxiety on functional disability. Furthermore, CCs mediated the impact of childhood maltreatment on functional disability via trait anxiety. Discussion: Clinicians may find these results useful to evaluate the mediating effects of CCs on the functional disability associated with childhood maltreatment and trait anxiety.
