Pilot Study Evaluating Critical Time Intervention for Individuals With Hoarding Disorder at Risk for Eviction.

Hoarding disorder has significant health consequences, including the devastating threat of eviction. In this pilot study, critical time intervention (CTI), an evidence-based model of case management shown to be effective for vulnerable populations, was adapted for individuals with severe symptoms of hoarding disorder at risk for eviction (CTI-HD). Of the 14 adults who enrolled, 11 participants completed the 9-month intervention. Completers reported a modest decrease in hoarding severity, suggesting that, while helpful, CTI-HD alone is unlikely to eliminate the risk of eviction for individuals with severe symptoms of hoarding disorder.

Augmenting Buried in Treasures with in-home uncluttering practice: Pilot study in hoarding disorder.

Hoarding disorder is characterized by difficulty parting with possessions and by clutter that impairs the functionality of living spaces. Cognitive behavioral therapy conducted by a therapist (individual or in a group) for hoarding symptoms has shown promise. For those who cannot afford or access the services of a therapist, one alternative is an evidence-based, highly structured, short-term, skills-based group using CBT principles but led by non-professional facilitators (the Buried in Treasures [BIT] Workshop). BIT has achieved improvement rates similar to those of psychologist-led CBT. Regardless of modality, however, clinically relevant symptoms remain after treatment, and new approaches to augment existing treatments are needed. Based on two recent studies - one reporting that personalized care and accountability made treatments more acceptable to individuals with hoarding disorder and another reporting that greater number of home sessions were associated with better clinical outcomes, we tested the feasibility and effectiveness of adding personalized, in-home uncluttering sessions to the final weeks of BIT. Participants (n = 5) had 15 sessions of BIT and up to 20 hours of in-home uncluttering. Reductions in hoarding symptoms, clutter, and impairment of daily activities were observed. Treatment response rate was comparable to rates in other BIT studies, with continued improvement in clutter level after in-home uncluttering sessions. This small study suggests that adding in-home uncluttering sessions to BIT is feasible and effective.

An investigation of the role of intolerance of uncertainty in hoarding symptoms.

BACKGROUND: Hoarding disorder (HD) is a common, debilitating mental illness and public health burden. Understanding the factors that contribute to hoarding is critical for identifying treatment targets. As a relatively new diagnostic entity, this research remains in its initial stages. Intolerance of uncertainty (IU) is thought to be a vulnerability factor for generalized anxiety disorder (GAD) and obsessive-compulsive disorder (OCD), and may also be relevant to HD. We investigated the possible association between IU and hoarding in two sets of analyses. METHOD: First, we administered self-report measures of IU and hoarding symptoms to unscreened undergraduate students (N=456) and used regressions to probe their association controlling for relevant covariates. Second, in a clinical sample, we compared IU across groups of patients with HD (N=26), GAD (N=26), OCD (N=51), other anxiety disorders (N=91) and healthy controls (N=29). RESULTS: In the student sample, IU predicted hoarding symptoms above and beyond relevant covariates, including hoarding-related beliefs. In the clinical sample, HD patients evidenced greater IU relative to healthy individuals and the mixed anxiety group, and comparable levels of IU to the GAD and OCD groups. LIMITATIONS: This study relied exclusively on self-report questionnaires and a cross-sectional design. CONCLUSIONS: IU is associated with hoarding behavior and, as we discuss, conceptual models might benefit from the study of IU as a potentially contributing factor. Directions for future research are discussed.

Acceptability of Treatments and Services for Individuals with Hoarding Behaviors.

OBJECTIVE: To explore the acceptability of currently available treatments and services for individuals who self-report hoarding behaviors. METHOD: Between 10/2013 and 8/2014, participants were invited to complete an online survey that provided them descriptions of eleven treatments and services for hoarding behaviors and asked them to evaluate their acceptability using quantitative (0 [not at all acceptable] -10 [completely acceptable]) Likert scale ratings. The a priori definition of acceptability for a given resource was an average Likert scale score of six or greater. Two well-validated self-report measures assessed hoarding symptom severity: the Saving Inventory-Revised and the Clutter Image Rating Scale. RESULTS: Two hundred and seventy two participants who self-reported having hoarding behaviors completed the questionnaire. Analyses focused on the 73% of responders (n=203) who reported clinically significant hoarding behaviors (i.e., Saving Inventory-Revised scores of ≥40). The three most acceptable treatments were individual cognitive behavioral therapy (6.2 ±3.1 on the Likert scale), professional organizing service (6.1 ±3.2), and use of a self-help book (6.0 ±3.0). CONCLUSION: In this sample of individuals with self-reported clinically significant hoarding behaviors (n=203), only 3 out of 11 treatments and services for hoarding were deemed acceptable using an a priori score. While needing replication, these findings indicate the need to design more acceptable treatments and services to engage clients and maximize treatment outcomes for hoarding disorder.

Effects of early adversity on young children's diurnal cortisol rhythms and externalizing behavior.

Early adversity is associated with biological and behavioral dysregulation in early childhood. We examined whether early adversity (i.e., poverty and involvement with child protective services [CPS]) had an indirect effect on externalizing behavior through HPA axis dysregulation, specifically blunted diurnal cortisol patterns. Participants included 94 children between the ages of 3.94 and 6.52 years old, who had a history of CPS involvement (n = 53) or no history of CPS involvement (n = 41). Cortisol samples were collected at wake-up and bedtime across 3 days, and parent-reported externalizing behavior was assessed using the Child Behavior Checklist. Results showed that history of CPS involvement and poverty were associated with blunted cortisol patterns, which in turn led to elevated externalizing behavior. The indirect effect of CPS involvement on externalizing behavior through blunted cortisol was significant, whereas the indirect effect of poverty on externalizing behavior was nonsignificant. Findings add to our understanding of neurobiological mechanisms linking early adversity to psychopathology.
