  The Hoarding Rating Scale is a commonly used measure of hoarding symptoms in which participants rate the severity of their symptoms. Minimum score is 0 and maximum score is 40. Higher scores indicate more severe/worse symptoms.

  Baseline, 10 weeks, 20 weeks, 24 weeks

• Changes in Reciprocal Attachment Questionnaire Adapted (RAQ-A)

  The Reciprocal Attachment Questionnaire Adapted assesses attachment to one's belongings, with higher scores indicating greater attachment to possessions (i.e., worse outcome). Minimum score is 75 and maximum score is 375.

  Baseline, 10 weeks, 20 weeks, 24 weeks

• Changes in Adult Attachment Scale (AAS)

  The AAS is a measure of two dimensions proposed to underlie interpersonal attachment security: anxiety and avoidance. Higher scores indicate worse outcomes. Minimum score is 0 and maximum score is 72.

  Baseline, 10 weeks, 20 weeks, 24 weeks

• Changes in Interpersonal Needs Questionnaire (INQ)

  The INQ is a measure of two interpersonal risk factors, namely perceived burdensomeness and thwarted belongingness, with higher scores indicating higher levels of each construct (i.e., worse outcome). Minimum score is 15 and maximum score is 105.

  Baseline, 10 weeks, 20 weeks, 24 weeks
