Exposure and response prevention (ERP) is the most empirically supported treatment for obsessive-compulsive disorder (OCD). However, details on how to effectively conduct ERP are lacking. The current study aimed to identify exposure parameters associated with better subsequent outcomes in ERP for OCD. We analyzed data from 271 therapy sessions across 46 participants in a randomized controlled trial comparing traditional ERP and ERP conducted from an acceptance and commitment therapy framework (ACT + ERP). Multilevel model results indicated that experiential delivery of acceptance/tolerance practice was associated with higher exposure homework adherence, lower psychological inflexibility, and less OCD symptom severity (except contamination) …

Hoarding symptoms include difficulty letting go of possessions, excessive acquisition, and clutter that precludes use of active living spaces. The current study compared the effects of acceptance training to psychoeducation on hoarding severity in a sample of college students with elevated hoarding symptoms. Participants (N = 47) completed self-report measures at baseline, posttest, and one-week follow-up and an in vivo discarding behavioral task at posttest. There were no differences in self-reported outcomes between conditions over time, suggesting acceptance training was not more effective than psychoeducation. Significant and large effect sizes for hoarding severity and maladaptive hoarding cognitions were found …

This study examined the function of hoarding behaviors and the relations between hoarding and a series of cognitive and affective processes in the moment using ecological momentary assessment. A matched-groups design was used to compare college students with higher hoarding symptoms (n = 31) and matched controls (n = 29). The two groups did not differ in what function they reported acquiring served, and positive automatic reinforcement was the most commonly reported function in both groups. Engaging in hoarding-relevant behaviors did not predict change in positive or negative affect when controlling for previous affect. Emotional reactivity and experiential avoidance in …
An Examination Of The Role Of Psychological Inflexibility In Hoarding Using Multiple Mediator Models, Clarissa W. Ong, Jennifer Krafft, Michael E. Levin, Michael P. Twohig

Hoarding is associated with functional impairment and impacts quality of life. One process that has been theorized to explain how hoarding develops and leads to impairment is psychological inflexibility, in which behavior is rigidly controlled by a perceived need to regulate internal experiences, at the expense of more effective, valued actions. The present study aimed to test the mediational role of psychological inflexibility in the development of hoarding and its impact on life satisfaction with a sample of 489 college students completing an online survey. Results indicated that multiple measures of psychological inflexibility (overall inflexibility, inattention, and values obstruction) mediated …
The Interaction Of Mindful Awareness And Acceptance In Couples Satisfaction, Jennifer Krafft, Jack Haegar, Michael E. Levin
The Interaction Of Mindful Awareness And Acceptance In Couples Satisfaction, Jennifer Krafft, Jack Haegar, Michael E. Levin

Past studies indicate that the awareness and acceptance facets of trait mindfulness both independently predict relationship satisfaction. However, this study hypothesized that the combination of awareness and acceptance might be a stronger contributor to relationship functioning than either in isolation. Regression analyses were used to test whether mindful awareness and acceptance interact in predicting couples satisfaction in a sample of dating or married college students (n = 138). Acceptance was positively associated with couples satisfaction, while awareness was unrelated. These two mindfulness facets interacted such that greater awareness was related to poorer satisfaction when acceptance was low, but was …
Decoupling As A Mechanism Of Change In Mindfulness And Acceptance: A Literature Review, Michael E. Levin, Jason B. Luoma, Jack Haegar

A growing body of research within the acceptance and mindfulness-based therapies suggests these treatments may function in part by reducing or eliminating (i.e., decoupling) the normative relationships between internal experiences and other internal/overt behavior. Examples of decoupling effects found in this review include reduced relationships between urges to smoke and smoking behavior, between dysphoric mood and depressive cognitions, and between pain intensity and persistence in a painful task. A literature review identified 44 studies on acceptance and mindfulness that demonstrated decoupling effects. Overall, preliminary evidence for decoupling effects were found across a broad range of problem areas including substance abuse, …
