To date, no studies have examined metacognition and IU within hoarding disorder (HD) symptoms. In this study, we examine the mediating role metacognition may play in the relationship between IU and HD and contrast it with a parallel model in OCD. We hypothesize that poorer metacognitions (low faith in cognitive abilities, thought monitoring, and magical thinking) will be associated with greater IU and will mediate the relationship with HD and OCD symptom severity. Participants and Methods: 2100 participants completed questionnaires via Amazon Mechanical Turk’s online platform. Participants were required to be 18 years or older and live in the United States. Demographic information, clinical symptom rating scales [the Hoarding Rating scale, Self-Report (HRS), Obsessive Compulsive Inventory-Revised (OCI-R)], the Metacognitive Questionnaire (MCQ-65), and the Intolerance of Uncertainty Scale (IUS) were completed by all participants. RStudio statistical package PROCESS was used to run models examining the mediating effect of the MCQ subscales Cognitive Confidence (CC), Cognitive Self-consciousness (CSC), and Superstition, Punishment, and Responsibility (SPR) on the relationship between IUS subscales [(Prospective anxiety (PA) and Inhibitory anxiety (IA)] in parallel models for HD symptoms and OCD symptoms. Results: The majority of participants were under 44 years old (74%), female (60%), and had a college degree (66%). Mean HD and OCD symptoms were below clinical cut-offs for their scales (HRS m=6.9, sd=8), OCI-R m=11.2, sd=11). In the OCD model, CC and SPR partially mediated the relationship between PA and OCD [(Total effect b= 0.709, p<0.001, CI95%= (0.64, 0.78)), (Direct effect b= 0.356, p<0.001, CI95%= (0.29, 0.42)]. CC and SPR partially mediated the relationship between IA and OCD [(TE b= 1.166, p<0.001, CI95%= (1.09, 1.25)), (DE b= 0.589, p<0.001, CI95%= (0.50, 0.67)]. In comparison for HD, CC and SPR fully mediated the relationship between PA and HD [(TE b= 0.252, p<0.001, CI95%= (0.20, 0.30)), (DE b= 0.027, p=0.285, CI95%= (-0.02, 0.08)]. CC and SPR partially mediated the relationship between IA and HD [(TE b= 0.652, p<0.001, CI95%= (0.59, 0.71)), (DE b= 0.262, p<0.001, CI95%= (0.20, 0.32)). CSC was not significant in any model. Conclusions: As expected, both PA and IA were associated with more severe HD symptoms and the relationship between PA and HD was fully mediated by negative metacognitive beliefs. IA was only partially mediated by CC and SPR with HD symptoms. This difference in a fully mediated model for HD with PA was notably different from the partial mediation of PA with OCD. Contrary to expectation, CSC had no mediating role. These findings suggest that low confidence in one’s cognitive abilities (CC), as well as magical thinking (SPR), play a key role in how IU differentially affects HD vs OCD symptoms.

Objective:

Previous research has found strong links between metacognition and intolerance of uncertainty (IU) with obsessive-compulsive disorder (OCD) symptoms. To date, no studies have examined metacognition and IU within hoarding disorder (HD) symptoms. In this study, we examine the mediating role metacognition may play in the relationship between IU and HD and contrast it with a parallel model in OCD. We hypothesize that poorer metacognitions (low faith in cognitive abilities, thought monitoring, and magical thinking) will be associated with greater IU and will mediate the relationship with HD and OCD symptom severity.

Participants and Methods:

2100 participants completed questionnaires via Amazon Mechanical Turk’s online platform. Participants were required to be 18 years or older and live in the United States. Demographic information, clinical symptom rating scales [the Hoarding Rating scale, Self-Report (HRS), Obsessive Compulsive Inventory-Revised (OCI-R)], the Metacognitive Questionnaire (MCQ-65), and the Intolerance of Uncertainty Scale (IUS) were completed by all participants. RStudio statistical package PROCESS was used to run models examining the mediating effect of the MCQ subscales Cognitive Confidence (CC), Cognitive Self-consciousness (CSC), and Superstition, Punishment, and Responsibility (SPR) on the relationship between IUS subscales [(Prospective anxiety (PA) and Inhibitory anxiety (IA)] in parallel models for HD symptoms and OCD symptoms.

Results:

The majority of participants were under 44 years old (74%), female (60%), and had a college degree (66%). Mean HD and OCD symptoms were below clinical cut-offs for their scales (HRS m=6.9, sd=8), OCI-R m=11.2, sd=11). In the OCD model, CC and SPR partially mediated the relationship between PA and OCD [(Total effect b= 0.709, p<0.001, CI95%= (0.64, 0.78)), (Direct effect b= 0.356, p<0.001, CI95%= (0.29, 0.42)]. CC and SPR partially mediated the relationship between IA and OCD [(TE b= 1.166, p<0.001, CI95%= (1.09, 1.25)), (DE b= 0.589, p<0.001, CI95%= (0.50, 0.67)]. In comparison for HD, CC and SPR fully mediated the relationship between PA and HD [(TE b= 0.252, p<0.001, CI95%= (0.20, 0.30)), (DE b= 0.027, p=0.285, CI95%= (-0.02, 0.08)]. CC and SPR partially mediated the relationship between IA and HD [(TE b= 0.652, p<0.001, CI95%= (0.59, 0.71)), (DE b= 0.262, p<0.001, CI95%= (0.20, 0.32)). CSC was not significant in any model.

Conclusions:

As expected, both PA and IA were associated with more severe HD symptoms and the relationship between PA and HD was fully mediated by negative metacognitive beliefs. IA was only partially mediated by CC and SPR with HD symptoms. This difference in a fully mediated model for HD with PA was notably different from the partial mediation of PA with OCD. Contrary to expectation, CSC had no mediating role. These findings suggest that low confidence in one’s cognitive abilities (CC), as well as magical thinking (SPR), play a key role in how IU differentially affects HD vs OCD symptoms.
