An Initial Test of Prototype Mobile App Interventions for Decluttering

The aim of the study is to investigate whether values clarification writing prompts administered via a prototype mobile application can help enhance motivation and facilitate decluttering in individuals with hoarding problems. This randomized control trial will help to (1) assess whether values clarification can improve outcomes in hoarding treatment by increasing motivation, (2) clarify which specific values clarification procedures are most beneficial, and (3) evaluate the impact of values clarification on overall symptoms and well-being. Participants will be randomly assigned to either the experimental group (receiving the values clarification intervention), psychological placebo group (self-reflection intervention), or the no intervention waitlist group.
