Brief Summary
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.

Outcome Measures
Primary Outcomes (1)
Saving Inventory - Revised (SI-R; Frost et al., 2004)
A self-report measure of hoarding symptoms grouped into three factors: excessive acquisition, difficulty discarding, and clutter. The SI-R consists of 23 items that are rated on a scale from 0 (e.g., no distress) to 4 (e.g., extreme distress). Scores range from 0 to 92, with higher scores indicate greater endorsement of hoarding disorder symptoms.

Study Arms (3)
Values Clarification Condition
EXPERIMENTALParticipants will be asked to respond to values clarification prompts twice a day over 28 days \[4 weeks\]. In each session, participants will receive a randomly assigned writing prompt from a pool of four categories: hierarchical, conditional, distinction, and perspective-taking prompts. In the initial session, participants will be asked to respond to a brief set of questions pertaining to their hoarding behavior in the past 12 hours and their motivation to declutter right now. From that point on, participants will respond to a brief set of questions before each writing prompt pertaining to their hoarding behaviors in the time since the previous writing prompt. After the writing prompt, they will be asked about how motivated they are to declutter right now. Each writing prompt is anticipated to take up to 10 minutes to complete and participants will receive notifications to use the app twice daily in addition email reminders twice a week to engage with the app.
Self-Reflection Condition
PLACEBO COMPARATORParticipants in this condition will be asked to respond to a set of randomly selected self-reflection prompts twice a day over 28 days \[4 weeks\]. As with the experimental condition, participants in the initial session will be asked to respond to a brief set of questions pertaining to their hoarding behavior in the past 12 hours and their motivation to declutter right now. From that point on, participants will be asked to respond to a brief set of questions before each writing prompt pertaining to their hoarding behaviors in the time since the previous writing prompt. After the writing prompt, they will be asked about how motivated they are to declutter right now. Each writing prompt is anticipated to take up to 10 minutes to complete, and participants will receive notifications to use the app twice daily in addition to email reminders twice a week to engage with the app.
Waitlist Condition
NO INTERVENTIONParticipants assigned to the waitlist will not receive access to any intervention for 8 weeks. After 8 weeks, they will receive access to either the values clarification or self-reflection mobile application.
Interventions
Participants in the intervention group will be asked to answer a series of values clarification writing prompts twice a day over four weeks.
Participants in the psychological placebo group will be administered writing prompts in the same format and frequency as the values intervention, but with prompts focused on self-reflection related to clutter and organization.
