Abstract
Individuals with hoarding disorder (HD) have difficulty parting with personal possessions, which leads to the accumulation of excessive clutter. According to a proposed biphasic neurobiological model, HD is characterized by blunted central and peripheral nervous system activity at rest and during neutral (non-discarding) decisions, and exaggerated activity during decision-making about discarding personal possessions. Here, we compared the error-related negativity (ERN) and psychophysiological responses (skin conductance, heart rate and heart rate variability, and end tidal CO2) during neutral and discarding-related decisions in 26 individuals with HD, 37 control participants with anxiety disorders, and 28 healthy control participants without psychiatric diagnoses. We also compared alpha asymmetry between the HD and control groups during a baseline resting phase. Participants completed a series of Go/No Go decision-making tasks, one involving choosing certain shapes (neutral task) and the other involving choosing images of newspapers to imaginally "discard" (discarding task). While all participants showed expected increased frontal negativity to commission of an error, contrary to hypotheses, there were no group differences in the ERN or any psychophysiological measures. Alpha asymmetry at rest also did not differ between groups. The findings suggest that the ERN and psychophysiological responses may not differ in individuals with HD during simulated discarding decisions relative to control participants, although the null results may be explained by methodological challenges in using Go/No Go tasks as discarding tasks. Future replication and extension of these results will be needed using ecologically valid discarding tasks.

Abstract
A persistent and influential barrier to effective cognitive-behavioral therapy (CBT) for patients with hoarding disorder (HD) is treatment retention and compliance. Recent research has suggested that HD patients have abnormal brain activity identified by functional magnetic resonance (fMRI) in regions often engaged for executive functioning (e.g., right superior frontal gyrus, anterior insula, and anterior cingulate), which raises questions about whether these abnormalities could relate to patients' ability to attend, understand, and engage in HD treatment. We examined data from 74 HD-diagnosed adults who completed fMRI-measured brain activity during a discarding task designed to elicit symptom-related brain dysfunction, exploring which regions' activity might predict treatment compliance variables, including treatment engagement (within-session compliance), homework completion (between-session compliance), and treatment attendance. Brain activity that was significantly related to within- and between-session compliance was found largely in insula, parietal, and premotor areas. No brain regions were associated with treatment attendance. The results add to findings from prior research that have found prefrontal, cingulate, and insula activity abnormalities in HD by suggesting that some aspects of HD brain dysfunction might play a role in preventing the engagement needed for therapeutic benefit.

Abstract
BACKGROUND AND OBJECTIVES Individuals with hoarding disorder, especially those with problems around acquiring, typically demonstrate a lack of motivation and awareness of their problematic behaviours. Since acquiring behaviours are important targets in interventions for hoarding, effective strategies for increasing motivation in this population are required to enhance the acceptability and efficacy of these interventions. METHODS The aim of the current study was to evaluate the ability of a brief online motivational intervention to reduce acquiring in a community sample of high acquirers (N = 159). Participants were randomly assigned to either a motivational interviewing protocol (n = 73) or progressive muscle relaxation control condition (n = 86). Readiness to change and motivation to acquire was measured via self-report, and acquiring behaviour was measured using a modified version of the Preston Acquisition Decision Making Task (to increase ecological validity). RESULTS In both conditions, participants' readiness and motivation to change increased over time. Contrary to hypotheses, the magnitude of this improvement did not significantly differ between conditions. Furthermore, conditions did not perform differently on the behavioural measure of acquiring. LIMITATIONS Insufficient dose of the intervention may have precluded any differences being observed between conditions. CONCLUSIONS Results underscore the need to better address the problem of lowered motivation in this population.

Abstract
BACKGROUND Cognitive behavioral therapy (CBT) is a moderately efficacious treatment for hoarding disorder (HD), with most individuals remaining symptomatic after treatment. The Joining Forces Trial will evaluate whether 10 weeks of in-home decluttering can significantly augment the outcomes of group CBT. METHODS A randomized controlled trial of in-home decluttering augmentation of group CBT for HD. Adult participants with HD (N = 90) will receive 12 weeks of protocol-based group CBT for HD. After group CBT, participants will be randomized to either 10 weeks of in-home decluttering led by a social services team or a waitlist. The primary endpoint is 10 weeks post-randomization. The primary outcome measures are the self-reported Saving Inventory-Revised and the blind assessor-rated Clutter Image Rating. Participants on the waitlist will cross over to receive the in-home decluttering intervention after the primary endpoint. Data will be analyzed according to intention-to-treat principles. We will also evaluate the cost-effectiveness of this intervention from both healthcare and societal perspectives. DISCUSSION HD is challenging to treat with conventional psychological treatments. We hypothesize that in-home decluttering sessions carried out by personnel in social services will be an efficacious and cost-effective augmentation strategy of group CBT for HD. Recruitment started in January 2021, and the final participant is expected to reach the primary endpoint in December 2024. TRAIL REGISTRATION ClinicalTrials.gov NCT04712474.

Abstract
This pilot study tested the utility of a virtual environment for assessing cognitive deficits characteristic of hoarding. A sample representing a broad spectrum of hoarding traits (N = 20) was assessed using self-report measures of information processing skills and emotional experience, and placed in a virtually simulated house that contained cluttered spaces and clean spaces. Information-processing significantly differed between high-hoarding and low-hoarding groups, with the high-hoarding group showing increased proneness to emotional attachment and information processing difficulties in the cluttered environment. The high-hoarding group also showed differences in behaviour and appraisal of the simulated environment. The findings suggested that virtual reality is accessible to participants and elicits real-time emotions and behavioural parameters which can assist our understanding of hoarding behaviour. Virtual reality may contribute to hoarding therapy in future, as it allows participants to visualise a different perspective of their condition and could contribute to their knowledge about the severity of their behaviour.

Abstract
PURPOSE OF REVIEW Cognitive behavioral therapy (CBT) with exposure and response prevention is the first-line treatment for obsessive-compulsive disorder (OCD) and related disorders such as body dysmorphic disorder (BDD). We review here recent developments in CBT and related therapies in treating OCD and related disorders. RECENT FINDINGS Superiority of CBT over medications in treating OCD is being questioned by some recent meta-analyses, nonetheless CBT continues to be the mainstay of treatment. Web-based therapies have been shown to be beneficial in treating at least mild-to-moderately ill patients. Mindfulness-based CBT, intensive residential treatment and Bergen 4-day concentrated exposure are also proving to be useful in treating OCD. Large well designed studies have demonstrated the efficacy CBT over supportive therapy in treating BDD. Research on the efficacy of CBT in treating hoarding disorder is accumulating. SUMMARY Efficacy of web-based CBT has a potential public health importance in that CBT may now become accessible to all and benefit at least mild-to-moderately ill patients who form most of the clinically ill sample. Similarly, efficacy of Bergen 4-day concentrated exposure will have a huge public health implication if the findings can be replicated in other centers across the world.

Abstract
Psychological treatment for hoarding problems has historically been associated with poor outcomes. When treated as a subgroup of obsessive-compulsive disorder, individuals with hoarding beliefs were less likely to respond to treatment than individuals exhibiting other obsessive-compulsive beliefs and behaviours. When treated as its own disorder using cognitive behavioural therapy, individuals report approximately 25% improvement in symptoms on average. However, less than a third of people experience clinically meaningful change. Further, changes in functioning and quality of life are not routinely assessed. In this paper, we review the current conceptualization and treatment of hoarding problems to shed light on how treatment for hoarding disorder may be improved. Utilizing a harm reduction approach before administering treatment may be important to ensure the safety of individuals. Research should test whether treatment outcomes improve by including strategies that enhance a client's interpersonal functioning and ability to regulate emotions (i.e., based on dialectal behaviour therapy and mentalization-based treatments), especially while discarding and organizing belongings. We should also use modern learning theory to improve the delivery of exposure activities.

Abstract
BACKGROUND Hoarding disorder (HD) is a new disorder in DSM-5. While cognitive-behavioral therapy (CBT) is seen as the gold standard approach to treatment, the literature in this field is still emerging. METHODS The aim of the present study is to synthesize the current treatment outcome literature on CBT for HD, as well as secondary depressive symptoms, using a meta-analytic approach. Due to a lack of controlled trials only within-group effect sizes were calculated. RESULTS Sixteen studies were included in the meta-analysis (n = 505; mean age = 56 years; mean percentage female participants = 72%). Large effect sizes were found from pre-treatment to post-treatment (g = 1.11; 95% CI: 0.92-1.29) and from pre-treatment to follow-up (g = 1.25; 95% CI: 0.94-1.56) on HD symptoms. The gender distribution of the sample moderated treatment outcome, with larger effects seen in studies that included a larger proportion of female patients. Treatment modality (individual vs group), therapist training, use of home visits, trial type (efficacy vs effectiveness), number of treatment weeks, participant age, and study quality did not moderate treatment outcome. Small effect sizes were found from pre-treatment to post-treatment (g = 0.45; 95% CI: 0.28-0.61) for depressive symptoms and baseline depression severity, treatment modality, use of home visits, and assessment tool used did not moderate outcome. LIMITATIONS The study is limited by the small number of studies available in this field. CONCLUSIONS This study demonstrates that CBT for HD is an effective treatment, however, controlled trials are needed, as are trials examining the long-term efficacy of CBT for HD.

Abstract
BACKGROUND Individuals with hoarding disorder (HD) demonstrate exaggerated subjective distress and hyperactivation of cingulate and insular cortex regions when discarding personal possessions. No prior study has sought to determine whether this subjective distress is associated with specific profiles of abnormal brain function in individuals with HD. METHODS We used multimodal canonical correlation analysis plus joint independent component analysis to test whether five hoarding-relevant domains of subjective distress when deciding to discard possessions (anxiety, sadness, monetary value, importance, and sentimental attachment) are associated with functional magnetic resonance imaging-measured whole-brain functional connectivity in 72 participants with HD and 44 healthy controls. RESULTS Three extracted components differed between HD participants and healthy control subjects. Each of these components depicted an abnormal profile of functional connectivity in HD participants relative to control subjects during discarding decisions, and a specific distress response profile. One component pair showed a relationship between anxiety ratings during discarding decisions and connectivity among the pallidum, perirhinal ectorhinal cortex, and dorsolateral prefrontal cortex. Another component comprised sadness ratings during discarding decisions and connectivity in the pallidum, nucleus accumbens, amygdala, and dorsolateral prefrontal cortex. The third component linked HD brain connectivity in several dorsolateral prefrontal cortex regions with perceived importance ratings during discarding decisions. CONCLUSIONS The findings indicate that in patients with HD, the subjective intensity of anxiety, sadness, and perceived possession importance is related to abnormal functional connectivity in key frontal and emotional processing brain regions. The findings are discussed in terms of emerging neurobiological models of HD.

Abstract
This shorter communication explores the concept of clinically significant change in treatment outcome studies for hoarding disorder. We argue that cross-study comparisons have been hindered due to researchers using different formulations to assess individual change. As a result, we propose that researchers adopt a standardized approach to calculating rates of clinically significant change for the Saving Inventory-Revised (SI-R) based on Jacobson and Truax's (1991) two-step method. Specifically, we recommend that individuals whose SI-R total scores have reduced by at least 20 points and whose post-treatment score is 38 or less be classified as recovered. Individuals whose total score decreases by 20 points or more, but whose post-treatment score remains above 38, should be classified as improved but not recovered. Individuals whose total score increases by 20 or more points should be classified as deteriorated. Any individual whose total score has changed by less than 20 points should be classified as not changed. By adopting these criteria, researchers will facilitate cross-study treatment outcome comparisons and aid in our understanding of the impact that hoarding treatment has on its recipients.

Abstract
Interventions for hoarding disorder need to target difficulty letting go of items to reduce clutter and improve functioning. The present studies were designed to test the efficacy of brief cognitive interventions for letting go of possessions and self-report outcomes. Participants (N = 67 in Study 1; N = 110 in Study 2) received training on defusion or distraction in Study 1 and defusion, self-as-context, or distraction in Study 2 and completed measures at pre- and postintervention. Study 1 found no differences between defusion and distraction on saving, self-rated discomfort with discarding, or perceived importance of the target belonging. In Study 2, participants provided most favorable feedback for self-as-context compared to defusion and distraction, indicating promise of this strategy. Nonetheless, findings from both studies overall provide minimal support for use of present procedures to reduce saving. Limitations include use of nonclinical samples and single-item variables to obtain participant feedback.

Abstract
Hoarding disorder is marked by strong attachments to everyday objects, extreme difficulties discarding, and impairing levels of clutter. We examined the associations between hoarding symptoms and associated clinical features using network analysis in a large sample of individuals with established hoarding disorder (n=217) and matched healthy controls (n=130). Network nodes included the three core features of hoarding (difficulties discarding, clutter, and acquiring), along with comorbid symptoms, impairment, and saving and acquiring motives. Models showed hoarding and comorbid symptoms as separate syndromes. Healthy and patient networks differed significantly in both global network strength and structure. For the hoarding patient network, the comorbidity and hoarding clusters were connected by acquiring and anxiety, which served as bridge symptoms. Clutter was the only hoarding node associated with impairment. Hoarding beliefs were not central to the model, and only difficulties discarding was associated with saving and acquiring motives, including emotional attachment and wastefulness beliefs. Our findings indicate that the network approach to mental disorders provides a new and complementary way to improve our understanding of the etiological model of hoarding, and may present novel hypotheses to examine in treatment development research.

Woody SR, Lenkic P, Bratiotis C, Kysow K, Luu M, Edsell-Vetter J, Frost RO, Lauster N, Steketee G, Tolin DF. How well do hoarding research samples represent cases that rise to community attention? Behav Res Ther 2020; 126:103555. [PMID: 32044474 PMCID: PMC10636773 DOI: 10.1016/j.brat.2020.103555] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2019] [Revised: 01/02/2020] [Accepted: 01/13/2020] [Indexed: 12/29/2022]
Abstract
This study used archival data from three different research groups and case file data from three independent community organizations to explore how well research samples reflect cases of hoarding that come to community attention. Using data from 824 individuals with hoarding, we found that research volunteers differ from community clients in several ways: community clients are older, more likely to be male and less likely to be partnered; they have lower socio-economic status and are less likely to demonstrate good or fair insight regarding hoarding severity and consequences. The homes of community clients had greater clutter volume and were more likely to have problematic conditions in the home, including squalor and fire hazards or fire safety concerns. Clutter volume was a strong predictor of these conditions in the home, but demographic variables were not. Even after accounting for the influence of clutter volume, the homes of community-based clients were more likely to have squalor. These findings suggest limitations on the generalizability of research samples to hoarding as it is encountered by community agencies.

Abstract
BACKGROUND Over the past decade, functional neuroimaging studies have found abnormal brain function in several cortical systems when patients with compulsive hoarding behaviors make decisions about personal possessions. The purpose of this study was to use functional magnetic resonance imaging to test a neurobiological model of hoarding disorder (HD) that has begun to emerge from these small studies by confirming HD-related brain dysfunction in previously implicated brain regions in the largest sample of HD patients examined to date. METHODS We compared 79 adults diagnosed with DSM-5 HD with 44 non-HD control participants using a functional magnetic resonance imaging task of decision making to acquire or discard material possessions and on a control task involving semantic processing. RESULTS HD brain activation profiles prominently featured insular and anterior cingulate cortex overengagement during possession-related choices that were not seen in non-HD brain activation profiles and also correlated with hoarders' clutter and difficulty discarding. Although HD patients overengaged the insula when deciding to discard, relative to when performing the non-decision making task contrast, the HD insula also was generally blunted. CONCLUSIONS This study links the defining behavioral symptoms of HD to localized brain dysfunction within cingulo-opercular brain systems and firmly establishes the context-dependent importance of this network dysfunction in HD. The relevance of dysfunction in these brain regions is highlighted by a failure to replicate HD-related abnormalities in other brain regions implicated in prior HD functional magnetic resonance imaging studies. This study also raises the novel possibility that HD may involve abnormality in the inferior frontal cortex engaged for executive control over semantic processing.

Abstract
Emotional distress tolerance (EDT) and emotion regulation (ER) appear to be highly relevant to hoarding pathology, as excessive saving and/or acquiring may be motivated by emotional avoidance or other attempts to regulate negative affect. While findings with nonclinical samples have suggested and EDT/ER predicts hoarding symptoms, there is little data on clinical samples. The aim of the current study was to examine several self-report measures of EDT and ER in individuals with HD (n = 87) and age-matched nonclinical controls (n = 46), and to explore whether this was predictive of treatment compliance and/or outcome in group CBT for HD. Results suggested that, the Difficulties in Emotion Regulation Scale (DERS; Gratz & Roemer, 2004) total score, DERS goals and awareness subscales, and Intolerance of Uncertainty Scale (IUS; Buhr & Dugas, 2002) were predictive of hoarding severity. However, EDT/ER did not change with treatment, did not mediate treatment outcome, and did not predicted treatment retention, compliance, or outcome. Results suggest that some EDT/ER constructs, such as uncertainty intolerance, difficulty persisting in goal behaviors when upset, and low emotional awareness, may explain significant variance in HD symptoms, although they did not appear to be mechanisms of change in CBT for HD.

Abstract
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.
