Abstract
This review addresses the translational relevance of animal models of stress and their effects on body weight. In humans, stress, whether chronic or acute, has often been associated with increased food intake and weight gain. In view of the current obesity epidemic, this phenomenon is especially relevant. Such observations contrast with reports with commonly used laboratory animals, especially rats and mice. In these species, it is common to find individuals gaining less weight under stress, even with potent social stressors. However, there are laboratory species that present increased appetite and weight gain under stress, such as golden hamsters. Furthermore, these animals also include metabolic and behavioral similarities with humans, including hoarding behavior which is also enhanced under stress. Consequently, we propose that our comparative perspective provides useful insights for future research on the development of obesity in humans as a consequence of chronic stress exposure.

Abstract
Life history theory provides a unified perspective for understanding human behaviors as adaptive strategies to specific environmental conditions. Within this theoretical framework, hoarding emerges as a behavior reflecting an evolved strategy in response to unpredictable environmental challenges, serving as a buffer against resource scarcity and enhancing survival prospects. This study aimed to explore the key roles of childhood environmental unpredictability, attachment, and sense of security in the development of hoarding. 662 participants completed scales on childhood environmental unpredictability, Revised Experiences in Close Relationships (ECR-R), sense of insecurity, and Savings Inventory-Revised (SI-R). The results showed that childhood environmental unpredictability was significantly positively correlated with hoarding. Attachment anxiety and sense of security individually mediate the effect of childhood environmental unpredictability on hoarding. Additionally, 'attachment anxiety--sense of security' and 'attachment avoidance--sense of security' serve as chain mediators in this relationship separately. This study offers insights into the cognitive-behavioral model of hoarding, highlighting the importance of life history theory in examining childhood environmental unpredictability's relationship with hoarding. It also integrates insights from the psychosocial acceleration theory into our comprehension of hoarding's development. Future research directions are also discussed.

Abstract
Hoarding behaviour sometimes requires intervention from community agencies to reduce risks to residents and the nearby community. Human services professionals from a wide range of disciplines are called upon to address hoarding concerns, often in collaboration with each other. No guidelines currently exist to guide staff from those community agencies in a shared understanding of common health and safety risks that occur with severe hoarding behaviour. Using a modified Delphi method, we aimed to generate consensus among a panel of 34 service-provider experts from a range of disciplines on essential risks in the home that would require intervention for health or safety reasons. This process identified 31 environmental risk factors that experts agreed are critical to assess in cases of hoarding. Panelist comments outlined the debates that commonly occur in the field, the complexity of hoarding, and the difficulty with conceptualizing risks in the home. The multi-disciplinary consensus achieved on these risks will facilitate better collaboration between agencies by providing a minimum standard of what to evaluate in hoarded homes to ensure health and safety standards are being met. This can improve communication between agencies, specify the core hazards that should be incorporated into training for professionals who work with hoarding, and facilitate more standardized assessment of health and safety risks in hoarded homes.

Abstract
BACKGROUND AND AIMS People with hoarding behaviours often struggle to engage in treatment. This study aimed to explore the experiences of a sample of people who identify as engaging in hoarding behaviours and who are seeking support. Exploring motivation to seek help, the barriers those who hoard face in accessing support and what facilitates accepting help, can aid understanding of how best to intervene. METHOD Eight individuals who self-identified as seeking help in relation to hoarding behaviours were recruited via social media and support groups. Interviews were conducted by telephone or video call, before being transcribed and analysed using interpretative phenomenological analysis. RESULTS Participants described complex help-seeking narratives and reported continued ambivalence about addressing their hoarding behaviours. The four group experiential themes identified were Wrestling with identity; Who can I trust?; Services don't fit; and Being overlooked: 'they're too busy looking at the thing, not the person'. Difficulties trusting others and services were identified; services were experienced as rejecting and many participants sought help for problems other than their hoarding. Problems accessing appropriate help for hoarding were predominant in the narratives, although participants who had accessed peer support described this as valuable. CONCLUSIONS There are both internal (e.g. fear of judgement; feeling overwhelmed) and external (e.g. service gaps) barriers that make finding useful help for hoarding behaviours very difficult. Services may facilitate those seeking help by taking a compassionate and person-centred approach to hoarding problems.

Abstract
Hoarding disorder is common and debilitating, especially in older adults, and novel treatment approaches are needed. Many current treatments emphasize skills related to discarding and decision-making about possessions, which can be practiced in the patient's home. However in many cases, in-home visits are unfeasible, or real-life discarding is too difficult. Virtual reality (VR) offers the ability to create a virtual "home" including 3D scans of the patient's actual possessions that can be moved or discarded. VR discarding is an alternative to in-home visits and an approach that provides a stepping stone to real-life discarding. VR has been successfully utilized to treat many disorders but tested minimally in hoarding disorder. In nine older adults with hoarding disorder, we tested an 8-week VR intervention administered to augment a 16-week Buried in Treasures group treatment. Individualized VR rooms were uniquely modeled after each patient's home. During clinician-administered VR sessions, patients practiced sorting and discarding their virtual possessions. The intervention was feasible to administer. Open-ended participant responses, examined by two independent evaluators, indicated that VR sessions were well-tolerated and that participants found them useful, with nearly all participants noting that VR helped them increase real-life discarding. Self-reported hoarding symptoms decreased from baseline to close, with seven of the nine participants showing reliable improvement in this timeframe and none showing deterioration. Results from this exploratory pilot study suggest that VR is a feasible way to simulate an at-home sorting and discarding experience in a manner that may augment skills acquisition. It remains an open question whether VR discarding practice yields greater improvement than existing treatments. VR for this population merits further clinical investigation.

Abstract
Hoarding behavior is prevalent in children and adolescents, yet clinicians do not routinely inquire about it and youth may not spontaneously report it due to stigma. It is unknown whether hoarding behavior, over and above obsessive-compulsive symptoms (OCS), is associated with major clinical factors in a general youth population. This observational study included N = 7054 youth who were not seeking help for mental health problems (ages 11-21, 54% female) and completed a structured interview that included evaluation of hoarding behavior and OCS, as a part of the Philadelphia Neurodevelopmental Cohort between November 2009 and December 2011. We employed regression models with hoarding behavior and OCS (any/none) as independent variables, and continuous (linear regression) or binary (logistic regression) mental health measures as dependent variables. All models covaried for age, sex, race, and socioeconomic status. A total of 374 participants endorsed HB (5.3%), most of which reported additional OCS (n = 317). When accounting for OCS presence, hoarding behavior was associated with greater dimensional psychopathology burden (i.e., higher P-factor) (β = 0.19, p < .001), and with poorer functioning (i.e., lower score on the child global assessment scale) (β = - 0.07, p < .001). The results were consistent when modeling psychopathology using binary variables. The results remained significant in sensitivity analyses accounting for count of endorsed OCS and excluding participants who met criteria for obsessive-compulsive disorder (n = 210). These results suggest that hoarding behavior among youth is associated with poorer mental health and functioning, independent of OCS. Brief hoarding-behavior assessments in clinical settings may prove useful given hoarding behavior's stigma and detrimental health associations.

Abstract
BACKGROUND A close association between obsessive-compulsive disorder (OCD) and attention-deficit/hyperactivity disorder (ADHD) in children and adolescents has been investigated in previous studies. However, few studies examined the relationship between lifetime comorbidity of ADHD and OCD in adults. Therefore, we sought to investigate the clinical and psychopathological features related to comorbid ADHD in Japanese adult patients with OCD. METHODS We assessed lifetime comorbidity of ADHD in 93 adult Japanese patients with OCD. Additionally, we used the Japanese version of Conners' Adult ADHD Rating Scales to assess the characteristics and severity of ADHD in each participant. According to the results, we excluded OCD patients that did not have ADHD but who exhibited elevated levels of ADHD traits. We compared OCD patients with ADHD (ADHD+ group) and those without ADHD or its trait (ADHD- group) in terms of background profiles and clinical features, such as OCD symptomatology and psychometric test results. Additionally, the 6-month treatment outcome was compared prospectively between groups. RESULTS Of the 93 OCD participants, the prevalence of lifetime comorbidity of ADHD was estimated as 16.1%. Compared with the ADHD- group, participants in the ADHD+ group had an earlier age of onset of OCD, higher frequencies of hoarding symptoms, higher levels of depressive and anxiety symptoms and lower quality of life, more elevated levels of impulsivity, and higher rates of substance or behavioral addiction and major depression. Finally, the mean improvement rate on the Yale-Brown Obsessive Compulsive Scale after 6 months of standardized OCD treatment in the ADHD+ group (16.1%) was significantly lower than that in the ADHD- group (44.6%). CONCLUSION The lifetime comorbidity of ADHD is likely to exert a significant effect on clinical features and treatment outcome in adult patients with OCD. It is important to consider that underlying ADHD pathology may function as a facilitator for increased severity of global clinical features and treatment refractory conditions in OCD patients. Further studies are required to examine treatment strategies for such patients.

Abstract
Misinformation or fake news has had multifaceted ramifications with the onset of the Covid-19 pandemic, creating widespread panic amongst people. This study investigates the impact of misinformation/ fake news (on internet platforms) on consumer buying behavior, impact of fear (created by fake news) on hoarding of essential products and consumer spending and finally impact of misinformation-induced panic buying on supply chain disruptions. It draws upon the consumer decision theory and the cognitive load theory for explaining the psychological and behavioral responses of consumers. The study follows an inductive approach towards theory building using a multi-method approach. Initially, a qualitative research method based on interviews followed by text-mining has been used followed by analysis using python for topic modelling using Latent Dirichlet Allocation (LDA). The findings revealed several prominent themes like consumer shift to online buying, two contrasting spending intentions namely financial security and compensatory consumptions, irrational panic buying, uncertainty/ambiguity of government protocol and norms, social media fraudulent practices and misinformation dissemination, personalized buying experience, reduced trust on news and marketers, logistics and transportation bottlenecks, labor shortage due to migration and plant closures, and bullwhip effect in supply chains.

Abstract
BACKGROUND Hoarding symptoms are associated with functional impairment, though investigation of disability among individuals with hoarding disorder has largely focused on clutter-related impairment to home management activities and difficulties using space because of clutter. This analysis assesses disability among individuals with hoarding symptoms in multiple domains of everyday functioning, including cognition, mobility, self-care, interpersonal and community-level interactions, and home management. The magnitude of the association between hoarding and disability was compared to that of medical and psychiatric disorders with documented high disability burden, including major depressive disorder (MDD), diabetes, and chronic pain. METHODS Data were cross-sectionally collected from 16,312 adult participants enrolled in an internet-based research registry, the Brain Health Registry. Pearson's chi-square tests and multivariable logistic regression models were used to quantify the relationship between hoarding and functional ability relative to MDD, diabetes, and chronic pain. RESULTS More than one in ten participants endorsed clinical (5.7%) or subclinical (5.7%) hoarding symptoms (CHS and SCHS, respectively). After adjusting for participant demographic characteristics and psychiatric and medical comorbidity, CHS and SCHS were associated with increased odds of impairment in all domains of functioning. Moderate to extreme impairment was endorsed more frequently by those with CHS or SCHS compared to those with self-reported MDD, diabetes, and/or chronic pain in nearly all domains (e.g., difficulty with day-to-day work or school: CHS: 18.7% vs. MDD: 11.8%, p < 0.0001) except mobility and self-care. While those with current depressive symptoms endorsed higher rates of impairment than those with hoarding symptoms, disability was most prevalent among those endorsing both hoarding and comorbid depressive symptoms. CONCLUSIONS Hoarding symptoms are associated with profound disability in all domains of functioning. The burden of hoarding is comparable to that of other medical and psychiatric illnesses with known high rates of functional impairment. Future studies should examine the directionality and underlying causality of the observed associations, and possibly identify target interventions to minimize impairment associated with hoarding symptomatology.

Abstract
The COVID-19 pandemic has necessitated the use of video-teleconferencing (VTC) for psychological treatments but VTC effectiveness studies are sparse. We examined treatment outcomes for a modified Buried in Treasures (BIT) group program for hoarding disorder (HD) delivered via VTC. Participants were 10 individuals with HD. Hoarding severity was evaluated at pre, mid, post, and six-month follow-up. Results showed significant decrease in hoarding symptoms over time (with an average decrease of 32%). The dropout rate was low (9%) and 30% of participants were fully recovered at follow-up. These results support the adaptation of in-person BIT for HD into a VTC format.

Abstract
BACKGROUND Home-care nurses are often the first care professionals to enter a dirty home. The perceived problems and support needs of home-care nurses in these situations are largely unknown. OBJECTIVE To examine the problems home-care nurses encounter in caring for patients living in dirty homes, and possible solutions for these problems. DESIGN Qualitative descriptive research. SETTING Communities across the Netherlands. PARTICIPANTS Twenty-three participants to investigate the problems or needs experienced, and 20 participants to investigate solutions. Participants included patients, home-care nurses and other professionals working in the community. METHODS Semi-structured interviews were conducted with 23 participants and analysed according to the principles of deductive thematic analysis. Subsequently, in interviews with 4 (representatives of) patients and four focus-group sessions with 16 professionals, the problems found were validated and solutions to the problems discussed. RESULTS Ten subthemes emerged that were clustered into three main themes: 'dilemmas arise in choosing the right nursing care'; 'cooperation and an integrated approach are often necessary, but lacking'; 'home-care nurses have insufficient competencies'. Seven possible solutions were found: (1) strengthening collaboration between organizations in the community; (2) involving others sooner; (3) case management; (4) person-centred care; (5) taking more time; (6) providing home-care nurses with tools and support services; and (7) strengthening the competencies of nurses. CONCLUSIONS Care for patients with a dirty home is complex. An integrated person-centred care approach is often necessary and home-care nurses need extra support to provide such care. Interventions should not only focus on patients, but address the nurses, the organization, and the collaboration between organizations in the community.

Abstract
We aimed at investigating the impact of the coronavirus pandemic on individuals with problematic hoarding behaviors. One hundred seventeen subjects with hoarding problems responded to the Coronavirus Stressful and Traumatic Rating Scale (COROTRAS), an instrument that quantified the number of coronavirus-related events, whether they were experienced as stressful, and the range of emotions resulting from them. The research subjects also answered self-report tools to evaluate the severity of hoarding, hoarding beliefs/motivations, social support, self-efficacy, internalized stigma, and other psychopathological symptoms. The number of stressful coronavirus-related events was predicted by lower age at onset of hoarding, decreased social support, greater severity of obsessive-compulsive symptoms, and lower intensity of concerns over memory as drivers of hoarding. Two emotional states experienced in the aftermath of trauma, namely greater helplessness and lower sadness, and higher depression, anxiety and distress, predicted greater severity of hoarding. In conclusion, we were able to find significant associations between hoarding disorder phenotypes and covid-19 related stressful events.

Abstract
BACKGROUND Biologging now allows detailed recording of animal movement, thus informing behavioural ecology in ways unthinkable just a few years ago. In particular, combining GPS and accelerometry allows spatially explicit tracking of various behaviours, including predation events in large terrestrial mammalian predators. Specifically, identification of location clusters resulting from prey handling allows efficient location of killing events. For small predators with short prey handling times, however, identifying predation events through technology remains unresolved. We propose that a promising avenue emerges when specific foraging behaviours generate diagnostic acceleration patterns. One such example is the caching behaviour of the arctic fox (Vulpes lagopus), an active hunting predator strongly relying on food storage when living in proximity to bird colonies. METHODS We equipped 16 Arctic foxes from Bylot Island (Nunavut, Canada) with GPS and accelerometers, yielding 23 fox-summers of movement data. Accelerometers recorded tri-axial acceleration at 50 Hz while we obtained a sample of simultaneous video recordings of fox behaviour. Multiple supervised machine learning algorithms were tested to classify accelerometry data into 4 behaviours: motionless, running, walking and digging, the latter being associated with food caching. Finally, we assessed the spatio-temporal concordance of fox digging and greater snow goose (Anser caerulescens antlanticus) nesting, to test the ecological relevance of our behavioural classification in a well-known study system dominated by top-down trophic interactions. RESULTS The random forest model yielded the best behavioural classification, with accuracies for each behaviour over 96%. Overall, arctic foxes spent 49% of the time motionless, 34% running, 9% walking, and 8% digging. The probability of digging increased with goose nest density and this result held during both goose egg incubation and brooding periods. CONCLUSIONS Accelerometry combined with GPS allowed us to track across space and time a critical foraging behaviour from a small active hunting predator, informing on spatio-temporal distribution of predation risk in an Arctic vertebrate community. Our study opens new possibilities for assessing the foraging behaviour of terrestrial predators, a key step to disentangle the subtle mechanisms structuring many predator-prey interactions and trophic networks.

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
We investigated changes in the severity of obsessive-compulsive and related disorders (OCRDs) symptoms as a result of the COVID-19 pandemic. An Amazon Mechanical Turk sample of 829 individuals was evaluated with a series of instruments assessing the severity of the OCRDs before and during the pandemic. Additional questionnaires about sociodemographic factors, personal and family histories of OCRD, COVID-19 related events, compulsivity and impulsivity traits, schizotypal symptoms, and the severity of depression, anxiety and stress levels, were also used. Participants reported that OCD, hoarding disorder (HD) and skin picking disorder (SPD) symptoms significantly worsened during the pandemic along with increased disability, more affective symptoms and reduced quality of life. Female gender, a higher number of COVID-19 related stressful events, and higher pre-COVID-19 fear of harm and symmetry symptoms predicted more severe OCD symptoms during the pandemic, whereas lack of a HD diagnosis by a mental health professional and more severe schizotypal symptoms predicted worsened hoarding symptoms. Greater compulsivity traits were associated with more severe COVID-19 pandemic obsessive-compulsive and hoarding symptoms. These data indicate that the immense distress resulting from the COVID-19 included significant deterioration of OCRDs' symptoms, particularly of OCD, HD and SPD. It was also possible to identify a pre-pandemic profile of people most at risk of pandemic-related deterioration in OCRDs' symptoms, which may prove valuable for preventative initiatives in relation to the likely future waves of COVID-19 or of other communicable diseases. Future studies should follow up these findings longitudinally.

Abstract
The formation of intense emotional attachments to objects, difficulty parting with possessions, and the extreme accumulation of clutter are key features of Hoarding Disorder (HD). Although substantial literature implicates processes such as dysfunctional beliefs and maladaptive emotional cycles in HD, little is known about the vulnerability factors that lead to their development and hoarding symptomatology. The current review sought to systematically collate and integrate findings from studies investigating the relationship between hoarding symptoms and three proposed vulnerability factors: i) interpersonal attachment, ii) early family environment, and iii) traumatic or adverse life events. A comprehensive search of the databases PsycInfo, PubMed, and Scopus identified a total of 39 studies for inclusion. The results presented a complex pattern that supported the presence of relationships between insecure attachment, cold and controlling family experiences, and exposure to adverse life events with increased hoarding severity. However, the specificity of these factors to HD over other clinical groups remains unclear and findings are limited by the heterogenous and small number of studies. We conclude by discussing the clinical implications and limitations of these findings and propose new directions for future research.

Abstract
The surge in panic buying during the novel Coronavirus (COVID-19) pandemic led to a temporary shortage of several staples and basic supplies in grocery stores, thus limiting the public's access to basic needs and exacerbating stress and anxiety. The negative societal consequences of panic buying highlight the importance of understanding and planning for such behavior. This study investigates the main factors that correlate with the perceived importance and timing of panic buying decisions in the US. In doing so, we provide a breakdown of the importance of panic buying across a list of common food and non-food grocery items and show a considerable variation based on product type. We also uncover heterogeneities in the importance and timing of panic buying based on demographic and behavioral characteristics, including residence area, household size, presence of children and elderly in the household, household income, ethnicity, and specific views about COVID-19. Finally, we analyze correlations between the importance of panic buying and various motivations that are believed to underlie this behavior. Results show that the perceived importance of panic buying is most heavily associated with the need for control, belief that it is the smart thing to do, and urge to minimize number of trips to grocery stores.

Abstract
This paper offers observations on people's lived experience of the food system in Michigan during the early Covid-19 pandemic as an initial critical foray into the everyday pandemic food world. The Covid-19 crisis illuminates a myriad of adaptive food behaviors, as people struggle to address their destabilized lives, including the casual acknowledgement of the pandemic, then anxiety of the unknown, the subsequent new dependency, and the possible emergence of a new normal. The pandemic makes the injustices inherent in the food system apparent across communities, demonstrating that food injustice destabilizes all members of the food system, regardless of their social location. The challenges of eating in a pandemic also reinforce the importance of building a sustainable food system; the challenges of food sovereignty and food sustainability are inextricably linked, and the pandemic lays this bare.

Abstract
The COVID-19 pandemic led to panic buying in many countries across the globe, preventing vulnerable groups from accessing important necessities. Some reports inaccurately referred to the panic buying as hoarding. Although hoarding is a separate issue characterised by extreme saving behaviour, the two problems may be influenced by similar factors. Participants from Australia and the United States (final N = 359) completed online self-report measures of panic buying, hoarding, shopping patterns, perceived scarcity, COVID-19 illness anxiety, selfishness, and intolerance of uncertainty. Our findings showed that panic buying was related to hoarding symptoms (r's = .23 - .36), and yet, both were uniquely associated with different psychological factors. Whilst panic buying was most strongly related to greater perceived scarcity (r's = .38 - .60), hoarding was most related to a general intolerance of uncertainty (r's = .24 - .57). Based on our findings, future strategies to prevent panic buying should focus on reducing perceived scarcity cues in the community, as this seems to be the primary driver of panic buying. Another preventative strategy to reduce excessive acquiring and saving may be to implement educational programs to increase people's ability to tolerate distress and uncertainty.

Abstract
Panic buying is a globally witnessed behavior during the outbreak of COVID-19. This consumer behavior is related to many undesirable consequences, ranging from disrupting economic stability to hindering timely provision of supplies to those in dire need. As such, to understand the causes and underlying mechanisms of panic buying is crucial. Based on terror management theory, this study examined the contribution of perceived risk, social media use, and connection with close others to panic buying. Data were collected through an online survey from 972 Chinese citizens (65.9% female, Mage = 33.69 years) at the beginning period of COVID-19 in early February 2020. The results found that individuals with a higher level of perceived risk were more prone to engage in panic buying, but this link was mitigated by connection with close others when individuals less used social media. Theoretically, this study advances the understandings of the psychological processes of panic buying during health crisis. Practically, alleviating individuals’ perceived risk, establishing a healthy habit of social media use, and strengthening social ties are important to circumventing panic buying in times of COVID-19.

Abstract
Hoarding disorder (HD), characterized by difficulty parting with possessions and functionally impairing clutter, affects 2-6% of the population. Originally considered part of Obsessive-Compulsive Disorder (OCD), HD became a distinct diagnostic entity in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) in 2013. While sleep impacts OCD, little is known about sleep in HD. As HD patients often report poor sleep in clinical settings, understanding global subjective sleep quality and disturbances may lead to novel therapeutic targets. To address this gap, the authors used a sample of convenience: an existing data set designed to screen research study eligibility and explore the psychopathology and phenomenology of OCD and HD. The data set included information collected from individuals with HD (n = 38), OCD (n = 26), and healthy participants (n = 22) about insomnia, sleep quality, and mood using interviews and structured instruments including the Insomnia Severity Index (ISI), Pittsburgh Sleep Quality Index (PSQI), and Depression Anxiety Stress Scales (DASS). In this data set, HD and OCD groups reported significantly greater insomnia symptoms and poorer sleep quality compared with healthy controls while controlling for depression, age, and gender. A sizable minority of HD and OCD individuals met criteria for comorbid sleep disorders. OCD and HD groups differed in delayed sleep phase prevalence. To our knowledge, this is the first study examining subjective sleep quality and insomnia in HD as compared to healthy individuals and those with OCD, while controlling for relevant clinical characteristics. Given that there are evidence-based treatments for insomnia and other sleep disorders, our study raises the possibility that treatment interventions targeting sleep may improve HD outcomes.

OBJECTIVE Hoarding is common in obsessive-compulsive disorder (OCD), and OCD with hoarding may have poorer prognostic features than OCD without hoarding. The aim of this study was to investigate the relationship between multifaceted impulsivity and hoarding symptoms in individuals with OCD. This relationship is important to be able to understand the psychopathological mechanisms of hoarding symptoms in OCD patients. METHODS The study included 136 individuals with OCD classified as OCD with high hoarding symptoms (OCDwHH, n = 41) and OCD with low/none hoarding symptoms (OCDwLH, n = 95), together with 94 healthy control subjects. All the participants completed the Hoarding Rating Scale-Interview, Barratt Impulsiveness Scale-11, Yale-Brown Obsessions and Compulsions Scale, Hamilton Depression Rating Scale, and Hamilton Anxiety Rating Scale. RESULTS The OCDwHH group had more severe anxiety (p = 0.016) and attentional impulsivity (p = 0.002) than OCDwLH. Attentional impulsivity scores were positively correlated with hoarding symptom scores (p < 0.001). Both attentional and motor impulsivity scores were positively correlated with anxiety levels (p = 0.037, p = 0.045, respectively). In partial correlation analysis, motor impulsivity was positively correlated with the severity of hoarding symptoms controlling for anxiety severity (p = 0.045). In hierarchical linear regression analysis, only attentional impulsivity predicted the severity of hoarding symptoms independently of anxiety, severity of obsessive-compulsive symptoms and motor impulsivity (β = 0.268, Adjusted R2 = 0.114, p = 0.006). CONCLUSION Attentional impulsivity is associated with hoarding symptoms in OCD. Future studies that reveal this relationship may contribute to treatment modalities for the OCD patients with hoarding symptoms.

Abstract
Hoarding behaviors are positively associated with medical morbidity, however, current prevalence estimates and types of medical conditions associated with hoarding vary. This analysis aims to quantify the medical morbidity of hoarding disorder (HD). Cross-sectional data were collected online using the Brain Health Registry (BHR). Among 20,745 participants who completed the Hoarding and Clutter and Medical History thematic modules, 1348 had HD (6.5%), 1268 had subclinical HD (6.1%), and 18,829 did not meet hoarding criteria (87.4%). Individuals with HD were more likely to report a lifetime history of cardiovascular/metabolic conditions: diabetes (HD adjusted odds ratio (AOR):1.51, 95% confidence interval (CI):[1.20, 1.91]; subclinical HD AOR:1.24, 95% CI:[0.95, 1.61]), and hypercholesterolemia (HD AOR:1.24, 95% CI:[1.06, 1.46]; subclinical HD AOR:1.11, 95% CI:[0.94, 1.31]). Those with HD and subclinical HD were also more to report chronic pain (HD AOR: 1.69, 95% CI:[1.44, 1.98]; subclinical HD AOR: 1.44, 95% CI:[1.22, 1.69]), and sleep apnea (HD AOR: 1.58, 95% CI:[1.31, 1.89]; subclinical HD AOR:1.30, 95% CI:[1.07, 1.58]) than non-HD participants. For most conditions, likelihood of diagnosis did not differ between HD and subclinical HD. Structural equation modeling revealed that more severe hoarding symptomatology was independently associated with increased cardiovascular/metabolic vulnerability. The assessment and management of medical complications in individuals with HD is a fundamental component in improving quality of life, longevity, and overall physical health outcomes.

Abstract
OBJECTIVE To explore whether the coronavirus disease 2019 (COVID-19) pandemic is associated with toilet paper hoarding and to assess which risk factors are associated with the risk of toilet paper hoarding. DESIGN A systematic review and realist review were conducted. DATA SOURCES PubMed, Web of Science, Scopus and PsycINFO were searched (systematic review). PubMed, pre-prints and grey literature were also searched (realist review). The databases were searched from inception until October 2020. STUDY SELECTION There were no restrictions on the study design. OUTCOMES AND MEASURES For the systematic review, toilet paper hoarding was the main outcome, and pathological use of toilet paper was the secondary outcome. For the realist review, the context-mechanisms-outcome (CMO) scheme included the COVID-19 pandemic (context), four proposed mechanisms, and one outcome (toilet paper hoarding). The four potential mechanisms were (1) gastrointestinal mechanisms of COVID-19 (e.g. diarrhoea), (2) social cognitive biases, (3) stress-related factors (mental illnesses, personality traits) and (4) cultural aspects (e.g. differences between countries). ELIGIBILITY CRITERIA FOR SELECTING STUDIES All studies of human populations were considered (including general population studies and clinical studies of patients suffering from mental health problems). RESULTS The systematic review identified 14 studies (eight studies for the main outcome, six studies for the secondary outcome). Three surveys identified the role of the COVID-19 threat in toilet paper hoarding in the general population. One study pointed to an association between a personality trait (conscientiousness) and toilet paper buying and stockpiling as well as an additional significant indirect effect of emotionality through the perceived threat of COVID-19 on toilet paper buying and stockpiling. Six case reports of pathological use of toilet paper were also identified, although none of them were associated with the COVID-19 pandemic. The realist review suggested that of all the mechanisms, social cognitive biases and a bandwagon effect were potential contributors to toilet paper hoarding in the general population. The stressful situation (COVID-19 pandemic) and some personality traits (conscientiousness) were found to be associated with toilet paper hoarding. Cultural differences were also identified, with relatively substantial effects of toilet paper hoarding in several Asian regions (Australia, Japan, Taiwan and Singapore). CONCLUSIONS The COVID-19 pandemic has been associated with a worldwide increase in toilet paper hoarding. Social media and social cognitive biases are major contributors and might explain some differences in toilet paper hoarding between countries. Other mental health-related factors, such as the stressful situation of the COVID-19 pandemic, fear of contagion, or particular personality traits (conscientiousness), are likely to be involved.

Abstract
At the onset of the coronavirus pandemic, sales of nonperishable food drastically increased in Germany. Reports of hoarding and panic buying flooded the media. To identify the drivers of the increased sales of these products, we carried out an online survey with n = 495 people living in Germany. We followed a concurrent triangulation design. For the quantitative analysis, we extended the theory of planned behavior to identify possible reasons for stockpiling nonperishable food. The results suggest that "attitude," "subjective norm," and the "fear of future unavailability" were main drivers of stockpiling behavior in our sample. Additionally, we analyzed answers to open questions capturing participants' own explanations of why they did or did not stockpile nonperishable food. By contrasting the results, we found that our qualitative results validate some of our quantitative findings but also deliver new insights. For instance, a key stated reason for stockpiling nonperishable food was to reduce shopping frequency.

Abstract
BACKGROUND Although past research shows hoarding to be associated with stressful life events involving loss and/or deprivation, the temporal relationship between the onset of symptoms and these events is not completely clear. OBJECTIVES In a cross-sectional online study, we examined the relationship between the number of events involving loss or deprivation before/simultaneously vs. after the onset of hoarding and various hoarding-related beliefs, such as emotional attachment to possessions, and symptom severity. Further, we examined whether perceived social support moderated the influence of these events on emotional attachment to objects. METHODS One hundred seventeen subjects with hoarding problems responded to a series of instruments to assess the history and timing of traumatic and stressful loss and/or deprivation in relation to the onset of hoarding, and self-report tools evaluating the severity of hoarding, beliefs/motivations, depression, anxiety, general distress, and perceived social support. RESULTS The number of events involving loss or deprivation occurring before hoarding was related to increased emotional attachment to possessions, whereas events happening after the onset of hoarding were related to increased concerns about memory as drivers of hoarding symptoms. Events happening before hoarding did not interact with perceived social support to influence emotional attachment to objects. CONCLUSIONS The timing of traumatic and stressful life events related to loss and deprivation is associated with different hoarding phenotypes, including beliefs/motivations for hoarding. If confirmed by longitudinal studies, these findings may be relevant for therapeutic and preventive measures.

Abstract
We develop an econometric model of consumer panic (or panic buying) during the COVID-19 pandemic. Using Google search data on relevant keywords, we construct a daily index of consumer panic for 54 countries from January 1st to April 30th 2020. We also assemble data on government policy announcements and daily COVID-19 cases for all countries. Our panic index reveals widespread consumer panic in most countries, primarily during March, but with significant variation in the timing and severity of panic between countries. Our model implies that both domestic and world virus transmission contribute significantly to consumer panic. But government policy is also important: Internal movement restrictions - whether announced by domestic or foreign governments - generate substantial short run panic that largely vanishes in a week to ten days. Internal movement restrictions announced early in the pandemic generated more panic than those announced later. Stimulus announcements had smaller impacts, and travel restrictions do not appear to generate consumer panic.

Abstract
The Hoarding Rating Scale, Self Report (HRS-SR) is a 5-item assessment developed to ascertain the presence and severity of hoarding symptoms. This study aimed to evaluate the validity of an online adaptation of the HRS-SR in a remote, unsupervised internet sample of 23,214 members of the Brain Health Registry (BHR), an online research registry that evaluates and longitudinally monitors cognition, medical and psychiatric health status. Convergent validity was assessed among a sub-sample of 1,183 participants who completed additional, remote measures of self-reported hoarding behaviors. Structured clinical interviews conducted in-clinic and via video conferencing tools were conducted among 230 BHR participants; ROC curves were plotted to assess the diagnostic performance of the internet-based HRS-SR using best estimate hoarding disorder (HD) diagnoses as the gold standard. The area under the curve indicated near-perfect model accuracy, and was confirmed with 10-fold cross validation. Sensitivity and specificity for distinguishing clinically relevant hoarding were optimized using an HRS-SR total score cut-off of 5. Longitudinal analyses indicated stability of HRS-SR scores over time. Findings indicate that the internet-based HRS-SR is a useful and valid assessment of hoarding symptoms, though additional research using samples with more diverse hoarding behavior is needed to validate optimal cut-off values.

Abstract
In a nationally representative sample from Poland (N = 755), we examined the relationships between the Dark Triad traits (i.e., psychopathy, Machiavellianism, and narcissism) and collective narcissism (i.e., agentic and communal) on the one hand, and behaviors related to the COVID-19 pandemic at (1) the zero-order level, at (2) the latent variance level, and (3) indirectly through health beliefs about the virus (i.e., the health belief model) on the other. We focused on preventive and hoarding behaviors as common reactions toward the pandemic. Participants characterized by the Dark Triad traits engaged less in prevention and more in hoarding, whereas those characterized by collective narcissism engaged in more hoarding only. Coronavirus-related health beliefs mediated patterns of prevention (fully) and hoarding (partially) in the latent Dark Triad (Dark Core) and collective narcissism. However, specific beliefs worked in opposite directions, resulting in a weak indirect effect for prevention and a null indirect effect for hoarding. The results point to the utility of health beliefs in predicting behaviors during the pandemic, explaining (at least in part) problematic behaviors associated with the dark personalities (i.e., Dark Triad, collective narcissism).

Abstract
There is little existing research on why some people stockpile goods and others do not at a time of crisis. More research on this phenomenon and the individual differences associated with it is needed in order to gain a better understanding of what is a potentially economically and socially disruptive behavior. In this study, 175 adult participants from Denmark and 90 from the United Kingdom responded to a survey about the activity of extra shopping (stockpiling) during the first weeks of the Coronavirus outbreak. Questions exploring the "big five" personality traits, Social Dominance Orientation, Health Literacy, and attitudes to the governmental response to the crisis were included in the survey. The explorative analysis showed that stockpiling was associated with high scores on Extraversion and Neuroticism, and low scores on Conscientiousness and Openness to Experience. Stockpiling was also associated with the view that the government should be doing more to stop the Coronavirus epidemic. An explorative factor analysis of reasons for stockpiling identified the two factors "Panic" and "Action".

Abstract
In this research, we document some of the many unusual consumer behavior patterns that came to dominate the early days of the COVID-19 pandemic. We offer insights based on theory to help explain and predict these behaviors and associated outcomes in order to inform future research and marketing practice. Taking an environmentally-imposed constraints point of view, we examine behaviors during each of three phases: reacting (e.g., hoarding and rejecting), coping (e.g. maintaining social connectedness, do-it-yourself behaviors, changing views of brands) and longer-term adapting (e.g. potentially transformative changes in consumption and individual and social identity). We discuss implications for marketing researchers and practice.

Abstract
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.

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
The presence of hoarding behavior among patients with schizophrenia has been known for more than a century. Nevertheless, only a few studies have examined the hoarding phenomenon among patients with schizophrenia, and no studies have examined the potential motivation. Hoarding disorder became a separate diagnosis in DSM-5. Studies about hoarding disorder use primarily quantitative approaches (e.g., scales, self-administered questionnaires, and structured interviews) when assessing the patients. The main objectives of this study were to examine the meaning of hoarding for patients with schizophrenia spectrum disorders and to explore associated psychopathology which may motivate the hoarding. We have examined 13 patients diagnosed with schizophrenia spectrum disorders showing hoarding behavior. The patients underwent semistructured, narrative interviews about the following domains: the time of onset of hoarding, the meaning of hoarding and associated psychopathology, the presence of insight into hoarding, and problematic issues about discarding. The study shows that hoarding begins very early in life for these patients and can be motivated by various psychopathologies. Diminished sense of basic self and transitivistic experiences were mentioned by several patients as motivations for collecting objects. Furthermore, the difficulty with discarding reflected a huge ambivalence and ruminations. Our findings suggest that thorough and comprehensive assessments of people with hoarding symptoms are necessary to assure the correct diagnosis and to understand the patient. An increased knowledge of the patients' motivations for hoarding behavior may also be useful for the treating personnel and may prevent social adversities. We think it is questionable that in the DSM-5 hoarding is not mentioned in the description of schizophrenia but has been elevated to a separate disorder.

Abstract
BACKGROUND Hoarding and obsessive-compulsive behaviours (OCB) are well documented symptoms in frontotemporal dementia (FTD). While contemporary models consider hoarding and obsessive-compulsive disorder distinct, the related behaviours have not been separately examined in patients with FTD, and the neuroanatomical correlates of hoarding in patients with FTD have not been previously examined (American Psychiatric Association, 2013; Grisham and Baldwin, 2015; Mataix-Cols et al., 2010). METHODS Patients with FTD who were evaluated between 2004 and 2018 at our centre were included. Cortical thickness and subcortical volumetric analyses were completed on available T1 high resolution anatomic scans using FreeSurfer. RESULTS Eighty-seven patients met inclusion criteria, and 49 had scans available for quantitative MRI volumetric analysis. New hoarding behaviours were present in 29% of patients and were more common in the semantic variant subtype of FTD, while 49% of individuals had new or increased OCB. Hoarding behaviours were associated with decreased thickness in a factor comprised of left temporal, insular and anterior cingulate cortices. The presence of OCB was predicted by reduced cortical thickness and volumes in a factor comprised of the anterior cingulate and subcortical volumes in the bilateral amygdala and hippocampus. OCB were associated with greater right temporal cortical thickness in comparison to patients with hoarding. DISCUSSION The association of the semantic variant with hoarding, together with the observed associations between left temporal atrophy and hoarding indicate that degeneration of the left temporal lobe has a role in the emergence of hoarding in FTD. As in current models of Hoarding disorder and Obsessive-Compulsive disorder, our results suggest that in patients with FTD, hoarding and OCB are clinically and anatomically partially dissociable phenomenon. The results may also help to further elucidate the cognitive processes and neural networks contributing to Hoarding disorder and Obsessive-Compulsive disorder in persons without dementia.

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
Hoarding, common in pediatric obsessive-compulsive disorder (OCD), has specific clinical correlates and is associated with poor prognosis. However, there are few studies of hoarding in pediatric OCD. This study estimates the occurrence of hoarding symptoms in a sample of children and adolescents with OCD, investigating possible differences in demographic and clinical variables between pediatric OCD with and without hoarding symptoms. Furthermore, the study investigates whether hoarding symptoms predict poorer treatment outcomes after cognitive behavioral therapy (CBT). The study sample comprised 269 children and adolescents with OCD, aged 7-17 years, from Denmark, Sweden, and Norway, who were all included in the Nordic long-term obsessive-compulsive disorder Treatment Study. All had an OCD diagnosis according to the DSM-IV and were treated with 14 weekly sessions of manualized, exposure-based CBT. Hoarding symptoms and OCD severity were assessed with the Children's Yale-Brown Obsessive-Compulsive Scale and group differences in treatment outcome were analyzed using linear mixed-effect modelling. Seventy-two patients (26.8%) had one or more symptoms of hoarding. Comorbid tic disorders (p = 0.005) and indecision (p = 0.024) were more prevalent among those with hoarding symptoms than those without hoarding symptoms. In addition, youth with hoarding symptoms had a different OCD symptom profile. Having symptoms of hoarding did not affect CBT outcome (p = 0.933). Results from the study suggest that CBT is equally effective for those with and without hoarding-related OCD.

Abstract
BACKGROUND The Saving Inventory - Revised (SI-R) is the most widely used self-report measure of hoarding symptom severity. The goal of this study is to establish a firm empirical basis for a cutoff score on the SI-R and to examine the functioning of the SI-R as a screening tool and indicator of hoarding symptom severity across the lifespan. METHODS This study used archival data from 1,116 participants diagnosed with a clinical interview in 14 studies conducted by research groups who focus on hoarding. We used receiver operating characteristic (ROC) analysis and the Youden's J statistic to determine optimal cutoff scores for classifying participants who would be likely to receive a hoarding diagnosis. RESULTS Overall, the discriminant performance of the SI-R Total score and each of the three subscales was high, confirming the status of the SI-R is an excellent screening tool for differentiating hoarding from non-hoarding cases. The optimal SI-R Total cutoff score is 39, although analyses suggested that older adults require a significantly lower cutoff and adults younger than 40 years require a significantly higher cutoff score. LIMITATIONS The confidence interval around the optimal cutoff for the SI-R Total score for oldest age group was wide in comparison to those reported for the younger groups, creating more uncertainty around the optimal cutoff score for this group. CONCLUSIONS This paper provides investigators and clinicians with the data necessary to select evidence-based cutoff scores on the SI-R that optimally suit their relative need for sensitivity and specificity in different age groups.

Abstract
OBJECTIVE Hoarding behavior is not limited to obsessive-compulsive disorder (OCD) alone. With the objective of highlighting the association between hoarding behavior and common psychiatric disorders, we explored its occurrence in psychiatric inpatients and co-occurrence with Axis I diagnoses. METHODS In this prospective cohort study, we enrolled adult psychiatric inpatients by simple random sampling at an urban, community-based, academic medical center. Patients were screened for hoarding using the validated Hoarding Rating Scale-Interview, and those meeting criteria for clinically significant hoarding were assessed for Axis I disorders. RESULTS Clinically significant hoarding was observed in 33% of the 200 acute psychiatry patients admitted to the study. Mood disorders were positively associated with hoarding (p = 0.033), whereas psychotic spectrum disorders had a weaker association with it (p = 0.015). CONCLUSION This study indicates a need for clinicians to be mindful that hoarding manifests in many forms of mental illness and is not limited to OCD alone.

Abstract
Behavioral impulsivity may be a mechanism of hoarding disorder (HD). A commonly used and well-validated measure of impulsivity is the delay and probability discounting task, which consists of making decisions about receiving monetary rewards after varying delay intervals and delivery probabilities. We compared delay and probability discounting and self-reported behavioral impulsivity in 81 patients with a primary diagnosis of HD and 45 nonclinical controls. HD participants completed the impulsivity measures before and after 16 weekly sessions of cognitive-behavioral therapy (CBT), whereas control group participants completed the measures before and after a 16-week waiting period. Despite the fact that self-reported impulsivity was greater in the HD group than the control group, delay and probability discounting did not differ between groups. Additionally, while self-reported behavioral impulsivity improved over the course of CBT in HD participants, delay and probability discounting did not change during treatment. Furthermore, higher delay discounting scores (i.e., greater preference for immediate rewards, indicating greater impulsivity) were associated with lower hoarding symptom severity. The findings suggest that self-reported impulsivity, but not objective performance on a behavioral impulsivity task, may be impaired in HD, and are discussed in terms of cognitive and affective factors in decision-making.

Abstract
Hoarding is linked to ambivalence and uncertainty about one's self and others. These notions are close to those constituting attachment representations. Hoarding is also linked to seeking support from objects. Studies concerning attachment and hoarding suggest that attachment representations may impact seeking or possessing objects. Acquiring objects may give people momentary support, normally provided by the attachment figure in cases of stress. This study aims to better understand the links between attachment and hoarding. One hundred and ninety-seven non-clinical women (M = 30.58) completed two self-report questionnaires on attachment and hoarding behaviors. The results show a link between insecure attachment (preoccupied and fearful) and hoarding. Preoccupied and fearful attachments are characterized by a fear of loss and abandonment. Possession and accumulation of objects in hoarding could help insecure people to deal with these fears. Therefore, insecure attachment appears to be a vulnerability factor in the development of hoarding behaviors.

Abstract
Individuals with elevated hoarding symptoms report elevated symptoms of ADHD and these symptoms are related to impaired daily functioning. Neuropsychological studies have found specific deficits in attention, and a recent review of attentional data from numerous hoarding studies concluded that inattention likely represents an etiological factor in hoarding, rather than a comorbidity. Our study aimed to examine which symptoms of ADHD, inattention or hyperactivity, are related to hoarding symptom severity, and whether individuals with hoarding symptoms display a neurophysiological marker of poor attention (Theta/Beta Ratio; THBR) that might explain these associations. The THBR indexes theta power relative to beta power in the frontal cortex and is often atypical in individuals with ADHD. We hypothesised that individuals would report more severe problems with inattention and would exhibit an elevated theta/beta ratio relative to a healthy control group. We also predicted that any relationship between hoarding and inattention would be independent of anxiety and depression symptoms. 17 hoarding-symptomatic participants and 16 healthy control participants completed self-report measures relating to ADHD, hoarding and general psychopathology, and then underwent resting measures of electroencephalography (EEG). Individuals with hoarding symptoms reported greater difficulties with inattention and hyperactivity, however they did not exhibit an elevated theta/beta ratio. When taking into account recent anxiety and depression, only inattention predicted hoarding symptom severity. Further investigations may help clarify this association and help inform attention-based treatments for hoarding.

Abstract
The Children's Saving Inventory (CSI) was introduced in 2011 and is the first parent-rated questionnaire specifically designed to measure the severity of hoarding symptoms in youth. To date, however, no replication studies of the CSI have been published. Additionally, the total CSI score includes several items measuring acquisition, a behavioural dimension that has since been excluded from DSM-5's hoarding disorder criteria. Given these limitations, the primary goal of the present study was to test a modified, DSM-5-consistent, total score of the CSI. Because a confirmatory factor analysis did not support the 2011 four-factor model of the CSI, we reviewed the original CSI and excluded all acquisition items. An exploratory factor analysis yielded a strong three-factor solution (difficulty discarding, Clutter, and distress/impairment) with good reliability and validity for a 15-item version of the CSI. Overall, our results support the use of the 15-item CSI in youth with OCD.

Abstract
OBJECTIVES Hoarding disorder (HD) is prevalent in older adults and contributes to morbidity and mortality. We attempted to estimate rates of hoarding amongst the elderly using the international Residential Assessment Instrument - Home Care (interRAI-HC). SETTING The interRAI is a mandatory prerequisite in New Zealand (NZ) for government-funded community support or for entry into aged residential care. PARTICIPANTS All 50 years and older people who were assessed using the interRAI in the southern district health board of NZ. MEASUREMENTS The age, gender, socially inappropriate or disruptive behaviour and squalor interRAI-HC items were analysed. RESULTS During the 3 years study period (Jan., 2015 to Dec., 2017) 6655 people, mean age 81.4 + 7.6 years, 56% female, were assessed. The interRAI socially inappropriate behaviour (includes hoarding as one of its descriptors) was present in 233 people (3.5%), herein defined as suspected HD. Squalid conditions were present in 98 additional people (1.5%). Mean age for suspected HD group was significantly younger [76.1 + 6.3 years (p < 0.001)] and there were more males [57% (p < 0.05)] compared with the general interRAI group. CONCLUSIONS Rates of HD estimated by using the interRAI are in line with published international data. As identification of HD with the interRAI is not straightforward it's use as a screening tool for identifying HD should be validated in future studies.

Abstract
OBJECTIVE Recent evidence suggests that avoiding waste may be a prominent motive to save in hoarding disorder. Such beliefs are reminiscent of scrupulosity obsessions in OCD. This paper reports on three studies examining scrupulosity-like beliefs in hoarding and the development and validation of a measure of material scrupulosity. METHODS Study one examined the reliability and validity of a measure of material scrupulosity (MOMS) and its relationship to hoarding in a college student sample, as well as the relationship between hoarding and OCD-base scrupulosity. Study 2 examined the psychometric properties of the MOMS in a replication of study 1 with a sample of people with hoarding problems. Study 3 examined the reliability and validity of the MOMS in a large nonclinical/community sample. RESULTS Findings across the studies provided evidence for the reliability and validity of the MOMS. It was highly correlated with hoarding symptoms, especially difficulty discarding, and hoarding related beliefs, especially responsibility beliefs. It accounted for significant variance in hoarding symptoms independent of other correlates, including other hoarding beliefs. OCD-based scrupulosity was correlated with hoarding in sample 1, but not in the hoarding sample in study 2. CONCLUSIONS Material Scrupulosity refers to an exaggerated sense of duty or moral/ethical responsibility for the care and disposition of possessions to prevent their being harmed or wasted. It appears to be distinct from other hoarding-related beliefs and a significant predictor of hoarding symptoms. The MOMS appears to possess good reliability and validity in both clinical and nonclinical samples.

Abstract
Binge eating (BE) is a heritable symptom of eating disorders associated with anxiety, depression, malnutrition, and obesity. Genetic analysis of BE could facilitate therapeutic discovery. We used an intermittent, limited access BE paradigm involving sweetened palatable food (PF) to examine genetic differences in BE, conditioned food reward, and compulsive-like eating between C57BL/6J (B6J) and DBA/2J (D2J) inbred mouse strains. D2J mice showed a robust escalation in intake and conditioned place preference for the PF-paired side. D2J mice also showed a unique style of compulsive-like eating in the light/dark conflict test where they rapidly hoarded and consumed PF in the preferred unlit environment. BE and compulsive-like eating exhibited narrow-sense heritability estimates between 56 and 73%. To gain insight into the genetic basis, we phenotyped and genotyped a small cohort of 133 B6J × D2J-F2 mice at the peak location of three quantitative trait loci (QTL) previously identified in F2 mice for sweet taste (chromosome 4: 156 Mb), bitter taste (chromosome 6: 133 Mb) and behavioral sensitivity to drugs of abuse (chromosome 11: 50 Mb). The D2J allele on chromosome 6 was associated with greater PF intake on training days and greater compulsive-like PF intake, but only in males, suggesting that decreased bitter taste may increase BE in males. The D2J allele on chromosome 11 was associated with an increase in final PF intake and slope of escalation across days. Future studies employing larger crosses and genetic reference panels comprising B6J and D2J alleles will identify causal genes and neurobiological mechanisms.

Abstract
Early life adversity, ranging from material deprivation and parental dysfunction to abusive and life-threatening events, has been associated with hoarding symptom severity. Moreover, both victims of early life adversity and individuals with hoarding disorder have been found to have a higher tendency toward detail-oriented visual processing. This study aimed to investigate the role of detail-oriented visual processing in the relationship between early life adversity and hoarding-related dysfunction. Childhood exposure to life adversity, hoarding symptom severity, and emotional attachment to possessions, a hoarding-related dysfunction thought to be most closely related to adversity exposure, were assessed. Detail-oriented visual processing was evaluated using the Central Coherence Index, which was calculated based on the drawing process during the Rey-Osterrieth Complex Figure Test. It was found that detail-oriented visual processing was not significantly associated with hoarding symptom severity, emotional attachment to possessions, or the relationship between early life adversity and hoarding symptom severity. It did, however, act as a significant moderator in the relationship between early life adversity and emotional attachment to possessions. These findings add to the literature by identifying the role of a specific neurocognitive processing style in the mechanism through which early life adversity affects the development of a key hoarding-related dysfunction, elevated emotional attachment to possessions.

Abstract
The present study investigated the association between pathological buying (PB) and identity processes and clusters. Forty-one patients with PB and 41 gender/age-matched controls (73% females) filled out the Dimensions of Identity Development Scale (DIDS), the Pathological Buying Screener, and self-report questionnaires to assess comorbid psychopathology, such as depressive symptoms, pathological internet shopping, and hoarding (excluding acquisition). Patients with PB reported significantly higher scores on ruminative exploration and lower scores on identity commitment processes compared to healthy controls. In the total sample, as well as in the PB sample, we identified four identity clusters: troubled diffusion, moratorium, foreclosure, and achievement, similar to Marcia's identity statuses. Patients with PB were overrepresented in the troubled diffusion cluster and less represented in the foreclosure and achievement clusters. Patients with PB in the troubled diffusion cluster scored significantly higher on PB, pathological internet shopping, hoarding, and depressive symptoms as compared to patients with PB in the other clusters. Based on these findings, we can conclude that patients with identity diffusion report more severe PB and related comorbid symptomatology. PB and related symptoms may be considered as coping strategies to deal with identity-related issues.

Abstract
BACKGROUND Hoarding disorder presents significant individual and interpersonal consequences. Because hoarding has only recently been added to the DSM, relatively little is known about associated comorbidity patterns. Several researchers have postulated a relationship between hoarding and schizotypy. To date, however, no investigations have considered which specific types of schizotypal traits relate to hoarding symptoms. METHODS We examined the association between hoarding and schizotypal symptoms using multivariate analyses in two samples-a sample of 120 young adults and a community sample of 291 individuals recruited from Mechanical Turk's online crowdsourcing system. RESULTS Individuals who fell within the clinical range on the Saving Inventory Revised endorsed significantly greater levels of schizotypal symptoms compared to those with normative saving behaviors. Odd speech, magical thinking, and social anxiety were the most consistent schizotypal correlates of hoarding symptoms. Perceived cognitive dysfunction mediated the effects between odd speech and social anxiety and hoarding symptoms, suggesting that shared abnormalities in cognitive functioning may help explain the relationship between hoarding and schizotypy. LIMITATIONS This study examined the spectrum of schizotypy and hoarding symptoms via self-report in two nonclinical populations. CONCLUSIONS Findings underscore the importance of assessing schizotypal traits in patients with hoarding, and suggest future avenues of research to better understand the underlying causes explaining the overlap, as well as potential treatment implications.

Abstract
When confronted with complex situations of hoarding and severe domestic squalor, small municipal communities and their partners frequently feel overwhelmed due to limited resources at their disposal. Stakeholders often report these situations to Public Health Service and seek their support. In order to facilitate more effective and coordinated actions, the main stakeholders involved (municipal, fire, police, public health and the regional health center) must agree on the most appropriate intervention strategies. An agreement providing services for the management of severe cases of domestic squalor in rural and semi-urban areas located in Quebec, Canada was produced by the Laurentians regional public health, and signed with fourteen local municipalities.
