Preliminary investigation of objective and subjective experiences of relatives of individuals with hoarding behaviors.

OBJECTIVE: Families of individuals with hoarding symptoms report substantial burden; however, there has been no investigation of potential positive experiences. The objective of this study was to examine the experiences reported by individuals with a relative with elevated hoarding symptoms using a cross-sectional design. The current investigation expands on the literature in this area by incorporating a detailed interview of experiences in conjunction with validated measures of hoarding symptomology. METHODS: Twenty-nine adults with relatives with elevated hoarding symptoms completed self-report measures of hoarding severity for themselves and their relative and a clinician-administered assessment of their experiences with their family member with hoarding symptoms. RESULTS: Participants endorsed significant burden across a range of areas, including permanent changes in their daily routine. The majority (93%) of participants reported at least one positive experience, with 69% endorsing companionship as a benefit of the relationship. Greater symptom severity of the relative with hoarding symptoms was associated with greater subjective burden and decreased positive experiences. CONCLUSION: Our results add further evidence to the potential for interpersonal psychotherapy to lead to a reduction in hoarding symptomology.

The Relationship Between Loneliness and Positive Affect in Older Adults.

OBJECTIVE: To establish whether positive affect (PA) is uniquely associated with loneliness and other social functioning variables beyond negative affect (NA) among older adults. METHODS: Four hundred and twenty-eight participants (aged 60+ years old, 82% White, and 48% female) were recruited using random digit-dialing and completed scales for loneliness (UCLA Loneliness Scale), companionship (PROMIS scale), satisfaction with discretionary social activities (PROMIS scale), PA (Center for Epidemiologic Studies [CES] Happiness Scale), and NA (CES-Depression scale and Brief Symptom Inventory-Anxiety Subscale). RESULTS: Multiple linear regression models found PA to be a significant predictor of lower loneliness where the effect of PA on loneliness is dependent on the level of NA; a large effect size at the mean level of NA, which becomes attenuated when NA increases. Although the direction of effect of PA on loneliness will change for NA > 5.10, which is 5 standard deviations away from 0, based on the model estimates, the percent of subjects with this large NA levels is practically 0. Thus, higher PA is associated with lower loneliness, however this effect is attenuated for larger NA. Similarly, multiple linear regression models found that companionship was associated with PA and NA where the effect of PA is dependent on the level of NA; a medium effect size at the mean level of NA, which becomes attenuated when NA increases. As in the case of loneliness, the direction of effect of PA on companionship will change for NA > 3.52, which is 3.5 standard deviation away from 0, based on the model estimates, but the percent of subjects with this large NA levels is practically 0. Thus, higher PA is associated with increased companionship, aand this effect is attenuated with greater NA. Satisfaction with social activities was associated with PA only (medium effect size). CONCLUSION: Results suggest PA appears to be uniquely associated with social functioning among older adults. These findings support the potential for treatments that target PA to decrease loneliness among older adults, or vice versa.

Implementation and evaluation of a community-based treatment for late-life hoarding.

OBJECTIVES: The objective of this paper was to examine the implementation and effectiveness of a community-based intervention for hoarding disorder (HD) using Cognitive Rehabilitation and Exposure/Sorting Therapy (CREST). DESIGN: This was a mixed-method, pre-post quasi-experimental study informed by the Practical, Robust Implementation and Sustainability Model for implementation science. SETTING: Program activities took place in San Diego County, mainly within clients' homes or community, with some activities in-office. PARTICIPANTS: Participants were aged 60 years or older, met eligibility for Medi-Cal or were uninsured, and met criteria for HD. INTERVENTION: A manualized, mobile protocol that incorporated CREST was utilized. MEASUREMENTS: The Clutter Image Rating and Hoarding Rating Scale were used as effectiveness outcomes. An investigator-created staff questionnaire was used to evaluate implementation. RESULTS: Thirty-seven clients were reached and enrolled in treatment and 15 completed treatment during the initial 2 years of the program. There were significant changes in hoarding severity and clutter volume. Based on the initial 2 years of the program, funding was provided for expansion to cover additional San Diego County regions and hire more staff clinicians in year three. CONCLUSION: Preliminary data suggest that the CREST intervention can be successfully implemented in a community setting with positive results for older adults with HD.

The Association Between Sleep and Late Life Hoarding.

Sleep problems are associated with many different forms of psychopathology in late life; however, there is currently a gap in the literature on the association between sleep quality and hoarding in older adults. This secondary data analysis of 40 older adults with hoarding disorder examined the association between sleep and hoarding, change in sleep disturbance following treatment, and the impact of sleep on treatment response. Sleep disturbance was correlated with hoarding severity, and this association remained significant when controlling for inability to sleep in a bed due to clutter in a multiple regression analysis. Following treatment, there was no change in sleep disturbance using a paired t-test, and baseline sleep disturbance was not correlated with change in hoarding severity. Future studies on the potential impact of sleep disturbance on hoarding treatment in older adults should examine if targeting sleep issues adjunctively could lead to improved sleep and improved treatment adherence/efficacy.

Personality traits in adults with hoarding disorder.

BACKGROUND: Prior research has demonstrated a link between compulsive hoarding symptoms and personality traits; however, no studies have investigated the link between hoarding and personality traits utilizing a sample of individuals diagnosed with hoarding disorder (HD) using formal diagnostic criteria. The aim of the current study was to evaluate the frequency and type of personality traits in adults diagnosed with HD and to explore the associations among hoarding severity and personality disorder traits within this sample. METHODS: Seventy-two veterans enrolled in an ongoing treatment trial for HD completed a battery of self-report measures during their initial assessment. Linear regression analyses were used to determine the unique variance accounted for by hoarding severity in predicting scores on the personality disorder scales from the Millon Clinical Multiaxial Inventory-III (MCMI-III). RESULTS: The majority of participants had an elevated score on at least one of the MCMI-III Personality scales. The most frequently elevated scores were for the Avoidant, Dependent, Depressive, and Schizoid scales. Hoarding severity was a significant predictor of personality traits in 10 out of 14 MCMI-III scales. LIMITATIONS: Given the exploratory nature of the investigation, we did not control for multiple comparisons or the presence of mood or anxiety disorders. CONCLUSIONS: The elevated prevalence of co-occurring personality pathology in adults with HD indicates the importance of considering underlying personality structure when developing individualized treatment plans.

Cognitive Rehabilitation and Exposure/Sorting Therapy for Late-Life Hoarding: Effects on Neuropsychological Performance.

OBJECTIVES: Hoarding disorder (HD) is characterized by urges to save items, difficulty discarding possessions, and excessive clutter and has been associated with executive functioning deficits. A randomized controlled trial comparing Cognitive Rehabilitation and Exposure/Sorting Therapy (CREST) with a care management control condition demonstrated the efficacy of CREST in reducing hoarding symptoms in older adults. The purpose of the current study was to assess whether CREST may also lead to improved executive functioning. METHOD: All participants were administered a neurocognitive battery at baseline and posttreatment. Linear mixed models with random intercepts were used to evaluate change in global neuropsychological functioning as well as change in individual executive functioning variables. RESULTS: There was no significant group by time interaction for the Global Deficit score; however, there were significant group by time interactions on two of the executive functioning variables examined, such that participants in the CREST condition demonstrated significant improvement in cognitive flexibility and inhibition over time compared with the participants in the care management condition. DISCUSSION: Our initial findings support the notion that CREST may be able to improve task switching, an important component of executive functioning, in older adults with HD.

Recent Advances in Research on Hoarding.

PURPOSE OF REVIEW: The purpose of the following paper is to review recent literature trends and findings in hoarding disorder (HD). Our goal is to highlight recent research on etiology, associated features, and empirically based treatments. RECENT FINDINGS: Recent literature has added support for cognitive differences as a risk factor for HD; however, there is evidence that individuals with HD may overestimate their level of cognitive impairment. Several associated features have been highlighted in recent studies, including emotion regulation, intolerance of uncertainty and distress intolerance, and attachment. Finally, several psychotherapeutic treatments for hoarding have been recently validated, including group-based therapy and treatments using the cognitive-behavioral model. Although recent research demonstrates that hoarding can be effectively treated with available psychotherapeutic modalities, the effectiveness of current treatments is not as robust as that for other psychiatric disorders and more work is needed in treatment precision.

Predictors of treatment outcome and attrition in adults with hoarding disorder.

While a number of hoarding disorder-specific therapeutic interventions have been developed over recent years, hoarding disorder (HD) remains difficult to treat. The purpose of this investigation is to inform HD treatment efforts by examining factors that influence treatment attrition and treatment response. Secondary data analysis of baseline and post-treatment data from two previously published psychotherapy treatment studies for hoarding were performed to identify predictors of hoarding symptom improvement and treatment attrition in 106 adults with HD. No demographic variables were associated with symptom improvement or treatment attrition. However, higher levels of avoidant coping (i.e., self-distraction combined with behavioral disengagement) significantly predicted symptom improvement. The maintenance stage of change along with high readiness for change also significantly predicted symptom improvement. Participants who dropped from treatment had significantly higher baseline levels of denial and clutter, both of which independently predicted treatment attrition. The findings from this study suggest that emotion-related constructs, such as managing stress and motivation for change, may play an important role in patients' response to and participation in HD treatment.
