ABSTRACT
Generalized anxiety disorder and obsessive-compulsive disorder are defined by chronic intrusive thoughts. The aim of the present study was to evaluate the relationship between cognitive (attentional control) and motivational (negative urgency) mechanisms potentially underlying worry and obsessions. Participants (N = 526) completed an online questionnaire battery consisting of self-report measures of worry, OCD symptoms, attentional control (AC), negative urgency (NU), and trait negative affect. After controlling for trait negative affect, self-reported AC was negatively related to worry, repugnant obsessions, and ordering symptoms. Greater NU was associated with increased worry and repugnant obsessions. Further, self-reported AC and NU interacted such that greater NU was associated with greater worry at high but not low levels of AC. AC and NU were independently associated with repugnant obsessions. Perceived executive functioning impairments may confer risk for intrusive thoughts, particularly worries, whereas distress-driven impulsivity may contribute to the involuntary, ego-dystonic features of intrusions.
ABSTRACT
Anxiety sensitivity (AS) cognitive concerns, which reflects fears of mental incapacitation, have been previously associated with suicidal ideation and behavior. The first study aim was to replicate and extend upon previous research by investigating whether AS cognitive concerns can discriminate between those at low risk versus high risk for suicidal behavior. Secondly, we aimed to test the incremental predictive power of AS cognitive concerns above and beyond known suicide risk factors (i.e., thwarted belongingness and insomnia). The sample consisted of 106 individuals (75% meeting current criteria for an Axis I disorder) recruited from the community. Results revealed that AS cognitive concerns were a robust predictor of elevated suicide risk after covarying for negative affect, whereas AS social and physical concerns were not. Those with high, relative to low, AS cognitive scores were 3.67 times more likely to be in the high suicide risk group. Moreover, AS cognitive concerns significantly predicted elevated suicide risk above and beyond relevant suicide risk factors. Results of this study add to a growing body of the literature demonstrating a relationship between AS cognitive concerns and increased suicidality. Incorporating AS cognitive concerns amelioration protocols into existing interventions for suicidal behavior may be beneficial.
