Brief summary

Hoarding Disorder (HD) is serious and disabling in Veterans. Present in up to 7% of Veterans and even higher symptom rates in older Veterans; HD contributes to functional impairment and poor quality of life. Cognitive Rehabilitation and Exposure/Sorting Therapy (CREST) has shown promising functional improvement and symptom reduction. To reduce burdens and barriers to implementation of CREST, the proposed project will individualize CREST based on cognitive testing and participant preferences, provide all care in the participant's home through telemedicine and home visits, and shorten the timeframe of treatment. A randomized controlled trial comparing 24 sessions of Personalized-CREST to case management for 130 adult Veterans with HD is proposed. Multifaceted functional and recovery outcomes including quality of life, HD severity, and sustained recovery outcomes will be examined throughout treatment and follow-up. By advancing the knowledge of the rehabilitative care of HD, we can interrupt the trajectory of this chronic and debilitating condition.

Detailed description

Hoarding Disorder (HD) is a chronic, progressive, and debilitating psychiatric condition that leads to devastating personal and public health consequences. HD is defined by persistent difficulty discarding or parting with possessions due to distress associated with discarding, urges to save, and/or difficulty making decisions about what to keep and what to discard. Subsequent accumulation of clutter can become so dangerous that it puts individuals at risk of falls, fires, infestations, food contamination, medication mismanagement, social isolation, nutritional deprivation, and eviction. Medical problems, activities of daily living (ADL) impairment, decreased quality of life, and functional disability are associated with HD symptom severity. HD starts early in life, does not remit if left untreated, and increases in severity with age. The highest rates of HD are seen in older adults, with up to 25% experiencing HD symptoms. The population of older Veterans is substantial, with 41% expected to be over the age of 65 by 2030. Recent research has found that Veterans with HD experience more medical and psychiatric comorbidities; thus, Veterans represent a group with high needs for effective HD treatment to reduce disability and improve multiple aspects of functioning. Dr. Ayers' group has developed and evaluated Cognitive Rehabilitation and Exposure/Sorting Therapy (CREST) in randomized controlled trials. The CREST intervention provides compensatory cognitive strategies to address the executive dysfunction typical of individuals with HD, and then uses exposure therapy to reduce the distress associated with discarding items. CREST improves HD symptoms and functioning in Veterans with HD, but the intensive nature of the program (6-8 months) burdens mental health clinics and slows progress. Given that the home is the primary site of clutter and the need for sorting of a large volume of items during treatment, a home-based treatment approach is needed. To reduce the burdens and barriers to implementation of CREST, the investigators will use a novel approach, referred to as Personalized-CREST, designed to reflect a precision medicine approach to evidence-based treatment for HD. Personalized-CREST will be more individualized (matching cognitive strategies to Veteran needs and priorities), more efficient (shorter timeframe over 12 weeks), and easier to access (in-home sessions and home-based video telemedicine \[HBVT\] sessions). Recent pilot data suggest that HBVT for HD is feasible, efficacious, requires minimal adaptation, and is a preferred. Based on 73 non-Veteran community Personalized-CREST completers, results indicated statistically significant decreases in functional impairment, disability, and of HD symptom severity. The proposed randomized controlled trial will compare Personalized-CREST to a case management (CM) control condition for 130 adult Veterans with HD. Personalized-CREST will be delivered twice a week in the home (one face-to-face and one HBVT session) for 60 minutes per session. A total of 24 sessions will be provided over 3 months. Per the standard of care for CM, a social worker will visit the Veteran once a week in their home. A thorough evaluation of treatment outcomes, including multifaceted functional and rehabilitative outcomes, including quality of life and hoarding severity will be conducted at baseline (0 months), mid-treatment, end of treatment (3 months), and 6-month follow-up. The investigators will also examine factors that mediate improvement in Personalized-CREST (improved executive functioning and reduction in avoidance of discarding items). Individual factors (e.g., age, baseline executive functioning, baseline HD severity, gender and economic factors) and treatment factors (e.g., attendance) will be explored as moderators. The proposed study will generate knowledge to advance the rehabilitative care of Veterans with HD.

Interventions

BEHAVIORALCognitive Rehabilitation and Exposure/Sorting Therapy

Cognitive Rehabilitation and Exposure/Sorting Therapy (CREST) provides training in compensatory cognitive strategies to address the executive dysfunction typical of individuals with HD, then helps reduce the distress associated with discarding items via exposure therapy.

BEHAVIORALCase Management

Case Management (CM). CM is the most widely available and utilized intervention for HD and is considered standard of care. This form of treatment involves managing the functional, housing, and legal ramifications of HD. Additionally, CM often involves assistance with economic, health, and social resources while providing support for the client.

Design outcomes

Primary

MeasureTime frameDescription
World Health Organization Disability Assessment Schedule (WHODAS 2.0) ChangeBaseline, 1.5 months, 3 months, and 9 monthsWorld Health Organization Disability Assessment Schedule (WHODAS 2.0) A 36-item, six domain (Cognitive, Mobility, Self-Care, Getting Along, Household, Work, Participation) assessment instrument developed by the World Health Organization (WHO) to provide a standardized method for measuring health and disability across cultures. The WHODAS has demonstrated high internal consistency, domain-specific reliability, and concurrent validity with similar disability measures. Total scores range from 0-100. Change is being assessed from baseline to post-treatment and again at follow-up.
Activities of Daily Living in Hoarding Scale ChangeBaseline, 1.5 months, 3 months, and 9 monthsThe Activities of Daily Living in Hoarding Scale is a 15-item measure that assesses functional impairments in daily activities due to hoarding behavior. The ADL-H assesses a respondents' ability to fulfill basic needs such as prepare meals, utilize appliances and furniture, move around the home, and exit the home. The ADL-H has demonstrated good test-retest reliability, internal and inter-rater reliability, and convergent and discriminant validity. Total scores range from 0-75. Change is being assessed from baseline to post-treatment and again at follow-up.
PROMIS-43 Profile v2.1 ChangeBaseline, 1.5 months, 3 months, and 9 monthsThe PROMIS-43 Profile v2.1 consists of a fixed collection of 6-item sets to assess global health and functioning (in physical, mental, and social domains). The PROMIS-43 assesses anxiety, depression, fatigue, pain interference, pain intensity (1-item), physical functioning, sleep disturbance, and ability to participate in social roles and activities. Substantial evidence supports the validity, reliability, and responsiveness to change of the PROMIS measures among adults with and without medical and mental health conditions. Total scores range from 0-275. Change is being assessed from baseline to post-treatment and again at follow-up.
Quality of Life in Neurological Disorders (Neuro-QoL) Positive Affect and Well-Being Short form ChangeBaseline, 1.5 months, 3 months, and 9 monthsQuality of Life will be assessed using the Quality of Life in Neurological Disorders (Neuro-QoL) Positive Affect and Well-Being Short form, a 9-item self-report measure that assesses sense of well-being, life satisfaction, purpose, and learning. The Neuro-QoL has demonstrated good internal consistency, test-retest reliability, and convergent and discriminant validity. A total score will be used for analyses and scores range from 0-9. Change is being assessed from baseline to post-treatment and again at follow-up.

Secondary

MeasureTime frameDescription
Savings Inventory-Revised (SI-R) ChangeBaseline, 1.5 months, 3 months, and 9 monthsHoarding symptom severity will be measured using the Savings Inventory-Revised (SI-R), a 23-item self-report measure used to assess common HD symptoms. Subtests include excessive clutter, compulsive acquisition, and difficulty discarding. The SI-R has demonstrated good internal consistency, concurrent validity, divergent validity, and test-retest reliability in clinical samples with HD. The total score will be used for analyses and scores range from 0-92. Change is being assessed from baseline to post-treatment and again at follow-up.
Clutter Image Rating Scale (CIR) ChangeBaseline, 1.5 months, 3 months, and 9 monthsThe Clutter Image Rating Scale (CIR) is a measure using a series of 9 photographs each of a kitchen, living room, and bedroom with varying levels of clutter. Participants and the rater independently select the photograph that most closely resembles each of the three rooms in the home. Internal consistency, test-retest reliability, and inter-rater reliability for the CIR were high, as well as correlations with validated hoarding measures. Scores range from 0-18. Change is being assessed from baseline to post-treatment and again at follow-up.
