NCT04239729

Brief Summary

This study will help to determine if acceptance and commitment therapy delivered as a web-based intervention is a useful treatment for hoarding disorder and evaluate whether or not web-based treatment for hoarding is credible and acceptable. It may also help identify novel processes of change in hoarding treatment such as psychological inflexibility, mindfulness, and self-stigma.

Study Arms (2)

ACT Website and Coaching Condition

EXPERIMENTAL

Participants will be asked to complete 16 brief self-help website sessions, each taking around 15-20 minutes to finish, twice a week for eight weeks. Website exercises and examples primarily focus on hoarding, although some examples also discuss related mental health concerns such as anxiety, low mood, health behaviors, etc. The sessions use multimedia and are interactive. Participants assigned to the website condition will also receive coaching. The purpose of coaching will be to help participants engage with the website and adhere to the intervention. Coaching will consist of an initial phone call of 10-15 minutes followed by weekly email contact during the 8-week treatment period. Coaches will be graduate students trained in clinical psychology.

Behavioral: ACT Website and Coaching

Waitlist Condition

NO INTERVENTION

Participants assigned to the waitlist will be asked to wait 12 weeks without intervention (access to the website or coaching). They will receive access to the website after 12 weeks, but supportive coaching will not be provided to waitlist participants.

Interventions

ACT Website and CoachingBEHAVIORAL

The ACT website includes sixteen sessions and is designed to teach a series of skills from ACT applied to hoarding. The intervention also includes brief supportive coaching (an initial phone call and weekly support over email).
