Outcome Measures

Primary Outcomes (2)

  • Hoarding Rating Scale Interview

    The Hoarding Rating scale has a total score ranging from 0 -40 with the higher score indicating higher symptoms of hoarding. This will be used to assess whether hoarding symptoms decrease as a result of treatment.

    22 weeks

  • Clinician's Global Impression Improvement and Severity ratings

    The CGI has a score range of 0-7 with the higher score indicating more severe symptoms.This will be used to assess whether hoarding symptoms decrease as a result of treatment.

Cognitive Rehabilitation and Exposure-based Class for Compulsi

EXPERIMENTAL

Cognitive training is to improve thinking by learning new skills and strategies. The class begins with cognitive training to increase ability to carry out the skills learned later in treatment. Exposure therapy for discarding and acquiring helps to improve ability to make choices about possessions and learn to tolerate anxiety. Participants will face making difficult choices about items and potentially letting them go. Through repeated exposure to decisions about discarding and acquiring, distress about letting go or making choices about items will decrease over time.

Behavioral: Cognitive Rehabilitation and Exposure-based Class for Compulsive Hoarding

Interventions

The group sessions consists of 20 classes, each lasting approximately 90 minutes and may consist of some or all of the following: * A group agreement and a confidentiality contract * Homework assignments * Viewing informational videos about hoarding * Behavioral experiments including sorting and discarding exercises * Non-acquisition exposures This course is based on the Manual Cognitive Rehabilitation and Exposure/Sorting Therapy for Compulsive Hoarding (Ayers et al., 2014).
