Clinical Trial Summary

This study will compare two behavioral interventions for hoarding disorder in older adults.

Description:

Hoarding disorder is a psychological condition with a unique constellation of consequences for older adults, including increased risk of fire and dying in a fire, insect infestation, and medical problems. Dangers related to cluttered living spaces are exacerbated by reduced executive functioning, attention, and concentration. Hoarding psychopathology results from maladaptive cognitions (e.g., desire to keep items others would discard) and maladaptive behavioral patterns (e.g., avoidance of sorting/discarding items).

Extant treatments for hoarding have targeted fear reduction as the mechanism of change, either through cognitive-behavioral therapy focusing on cognitive restructuring or behavior therapy focusing on exposure therapy. Older adults have a lackluster response to cognitive restructuring for hoarding, and, although exposure therapy increases treatment response, both approaches require a lengthy six-month dose. Our preliminary work suggests that fear reduction may not be a universally relevant target mechanism for older adults, and that to be responsive to the specific needs of older adults, other mechanisms need to be identified.

Motivational interviewing is a technique that is already typically incorporated into hoarding treatment and has been demonstrated to increase motivation for behavioral change across a range of health conditions for older adults, including physical activity, diet, and disease management. Because sorting/discarding is at its core a health behavior that hoarding patients lack the motivation to engage in, motivational interviewing is likely to decrease hoarding severity by eliciting increased levels of sorting/discarding.

The proposed project will use a mechanistic clinical trials approach to determine if a four-month intervention combining motivational interviewing with sorting practice can engage the proposed target, motivation for behavioral change, when compared to a four-month dose of sorting practice alone in a sample of rural-dwelling older adults with hoarding disorder.

Intervention

Behavioral:
• RECLAIM: Reducing Clutter and Increasing Meaning
Participants will receive 16 weekly 1-hour treatment sessions in their home delivered by Masters-level clinicians with the assistance of undergraduate researchers. Each treatment session will involve a combination of motivational interviewing (MI) and sorting practice. The rationale behind the sorting practice is to develop the skill of sorting and the formation of a daily sorting routine. The MI portion of the initial session will involve an evaluation of client strengths and individual biopsychosocial goals. The initial and subsequent sessions will include a variety of MI techniques, including decisional balancing, developing discrepancy, personalized feedback, and reinforcement of responsibility of sense of self-efficacy.
• Sorting Practice
Participants will receive 16 weekly 1-hour treatment sessions in their home delivered by Masters-level clinicians with the assistance of undergraduate researchers. Clinicians will encourage participants to sort objects during each session while refraining from use of any specific cognitive or motivational therapeutic techniques. Participants will be asked to record the frequency and duration of any sorting/ discarding they did during the previous week.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Change in score on the Saving Inventory-Revised (SI-R; Frost et al., 2004)	The SI-R is a 23-item measure of the three core hoarding symptoms (urges to save, difficulty discarding, and excessive clutter).	Four months
Other	Change in score on the Clutter Image Rating (CIR; Frost et al., 2008)	The CIR 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.	Four months
Other	Change in scores on the Behavioral Approach Task for sorting/discarding(BAT; Dozier & Ayers, 2017; Dozier et al., 2020)	The BAT involves the participant sorting items in a cluttered part of their home for 15 minutes. The speed of sorting and percentage of items discarded will be used as behavioral indicators of hoarding severity.	Four months
Primary	Change in frequency of sorting/discarding behavior	As a behavioral indicator of motivation to engage in sorting/discarding behavior, participants will be asked to report at baseline and at their weekly treatment sessions the frequency of sorting/discarding items in the previous week.	Four months
Primary	Change in duration of sorting/discarding behavior	As a behavioral indicator of motivation to engage in sorting/discarding behavior, participants will be asked to report at baseline and at their weekly treatment sessions the duration of sorting/discarding items in the previous week.	Four months
Primary	Change in score on the University of Rhode Island Change Assessment Questionnaire McConnaughy et al., 1983)	The URICA is a 32-item Likert scale that assesses readiness for change and includes four subscales that individually assess stage of change (Precontemplation, Contemplation, Action, and Maintenance). Previous investigations have found adequate internal reliability for the URICA in treatment-seeking samples (Dozois et al., 2004), including in older hoarding samples specifically (Ayers et al., 2019).	Four months
Primary	Change in score on the Apathy Evaluation Scale (AES-S; Marin, 1991)	The AES is an 18-item measure of an individual's deficits in goal-directed thoughts and behavior. The AES was developed specifically to assess apathy in adults aged 55+ and is predictive of motivation for behavioral change (Resnick et al., 2012).	Four months
Secondary	Rating on the Treatment Acceptability/ Adherence Scale (TAAS; Milsevic et al., 2015)	The TAAS is a 10-item self-report measure of a patient's perception of the acceptability of a treatment as well as their anticipated adherence to the protocol.	Immediately after session one
