Trial Outcomes & Findings for Motivational Interviewing to Enhance Behavioral Change in Older Adults With Hoarding Disorder (NCT NCT05237466)
NCT ID: NCT05237466
Last Updated: 2026-07-16
Results Overview
As a behavioral indicator of motivation to engage in sorting/discarding behavior, participants will be asked to report at their weekly treatment sessions the frequency of sorting/discarding items in the previous week. Data were analyzed as percentage of days sorted between sessions (assessed at sessions 2-16). Mixed effects models were used to analyze data such that participants with at least one timepoint were included in the analyses.

PRIMARY outcome
Timeframe: Four monthsThe University of Rhode Island Change Assessment Questionnaire (URICA) is a 32-item Likert scale that assesses readiness for change. Scores for readiness for change are calculated by subtracting pre contemplation items from the other summed items. Scores range from -2 to 14, with higher scores indicating greater readiness for change.

OTHER_PRE_SPECIFIED outcome
Timeframe: Four monthsThe Clutter Image Rating is a three-item pictorial rating scale of clutter level in the bedroom, kitchen, and living room. Assessor ratings of the CIR will be used for the proposed project. Scores of the three rooms are averaged to create a composite score ranging from 1-9, with higher scores indicating greater clutter levels.

OTHER_PRE_SPECIFIED outcome
Timeframe: Four monthsThe Behavioral Approach Task for sorting/discarding involves the participant sorting items in a cluttered part of their home for 15 minutes. The speed of sorting (# of items sorted) will be used as a behavioral indicator of hoarding severity. The lower limit is 0 items sorted; there is no upper limit of number of items to be sorted.
