Abstract
Objectives: Hoarding in older adults can have a detrimental effect on daily life. Repetitive negative thinking (RNT) could result in a greater avoidance of discarding and increased saving behaviors; yet, the unique role of RNT on hoarding in older adults remains understudied. This study aimed to investigate whether the intensity of RNT contributes to hoarding in older adults. Methods: Two hundred and sixty-four older adults in Japan (ages 65-86 years, 132 males and 132 females) participated in an online survey. Hierarchical regression analyses were conducted to examine whether RNT could significantly explain the variance of hoarding after controlling for age, sex, years of education, self-reported cognitive impairment, and depression. Results: As we expected, RNT was significantly associated with greater hoarding behaviors, such as excessive acquisition (β = .27, p = .005) and difficulty in discarding (β = .27, p = .003). On the other hand, reflection, repetitive thinking without negative emotional valence, was significantly associated with higher scores on clutter (β = .36 p < .001). Conclusion: Our findings highlight the importance of addressing RNT in the prevention and treatment of hoarding symptoms among older adults, potentially leading to more effective interventions and improved outcomes in managing hoarding behaviors in this population.

Abstract
Current research suggests obsessive-compulsive disorder (OCD) co-occurs in around 20% of people with hoarding disorder (HD). The article discusses the theoretical conceptualization of co-occurring HD and OCD (HD+OCD), highlighting similarities between the disorders that may contribute to comorbidity, such as potentially overlapping etiological factors, comorbidity profiles, and phenomenological aspects; and differences that are important to consider in differential diagnosis and conceptualization, such as belief patterns, ego-syntonicty/dystonicity, and trajectory. The combination of HD+OCD versus either disorder alone appears to be associated with a profile characterized by higher nonhoarding OCD symptoms, anxiety symptoms, depression, and tic disorders, and which may be more treatment-refractory. The authors discuss some commonly used measures to assess hoarding that may be relevant in the context of OCD, as differential diagnosis of hoarding behaviors is often difficult, and hoarding may be difficult to detect in patients with OCD, especially in children. The article ends with a discussion on considerations for the treatment of HD+OCD with cognitive-behavioral therapy, as hoarding symptoms are less likely to respond to gold-standard exposure and response prevention, and there are no established treatment protocols that are designed to treat co-occurring HD and OCD.

Abstract
Although hoarding symptoms are reported to begin in childhood and adolescence, the true prevalence of the disorder in this age group is unknown. This study aims to estimate the prevalence of hoarding disorder (HD) in children and adolescents. The present study was planned as a two-stage epidemiological research. In the first stage, the Children's Saving Inventory (CSI) and informed consent forms were delivered to a group of students' parents. In the second stage, one-on-one psychiatric interviews with a physician were planned with the families and children who had hoarding behavior (HB), as described by their parents. The DSM-5-based HD interview and the Development and Well-Being Assessment (DAWBA) diagnostic tool were used to detect prevalence of HD and comorbid psychiatric disorders. A total of 3249 children were included in the study, and 318 children and their parents were evaluated in the second stage. As a result of the second assessment, 32 out of 318 children met the HD diagnostic criteria. The estimated prevalence of HD was 0.98% (95% CI 0.7-1.4). Hoarding disorder was found more frequently in females (F/M = 3/1). After a logistic regression analysis, variables such as female sex and the presence of any psychopathology were identified as independent correlates of HD. More than half (56.2%) of the children diagnosed as having HD also had a comorbid psychiatric disorder. In the present study, the two-stage evaluation method was used in a large pediatric sample to determine the estimated prevalence of HD, as well as the factors associated with the disorder and comorbid psychiatric disorders.

Abstract
AbstractFew studies have investigated body-dysmorphic, hoarding, hair-pulling, and skin-picking symptoms in adolescents and how they relate to mental health, quality of life, suicide attempts, and non-suicidal self-harm. We used a quota sampling procedure and contacted 100 secondary centres in the Southeast of Spain, of which 34 participated in the study. A sample of 5,345 adolescents (12–18 years) completed dimensional measures of body-dysmorphic, hoarding, hair-pulling, and skin-picking symptoms. The proportion of adolescents with clinically significant symptoms within each symptom type was estimated and associations with other indicators of mental health examined. Clinically significant body-dysmorphic symptoms were reported by 3.7%, hoarding by 0.9%, hair-pulling by 0.7%, and skin-picking by 1.8%. Body-dysmorphic symptoms were more common in girls and in those over 14 years of age. Body-dysmorphic, hoarding, hair-pulling, and skin-picking symptoms were moderately to strongly associated with obsessive-compulsive symptoms, internalizing symptoms, externalizing symptoms, and poor quality of life. Those with significant body-dysmorphic, hoarding, hair-pulling, and skin-picking symptoms were much more likely to have attempted suicide and engaged in non-suicidal self-harm during the last twelve months than those without such symptoms. Body-dysmorphic symptoms showed the strongest associations with internalizing symptoms and poor quality of life. Limitations are the sole use of self-report and a sample from only two regions in Spain, but findings suggest that body-dysmorphic, hoarding, hair-pulling, and skin-picking symptoms are common and impairing during adolescence.

Abstract
Hoarding disorder (HD) involves extreme difficulties discarding possessions and significant clutter in living areas. Although hoarding occurs worldwide, cross-cultural research remains in nascent stages, hampered in part by a lack of validated measures in non-English languages. We aimed to validate a Spanish translation of the Hoarding Rating Scale (HRS), a widely used measure of core HD symptoms. Our sample (N=736) included participants responding in English (n=548; 45.4% female; 7.9% Latinx) or Spanish (n=188; 46.3% female; 79.9% Latinx) to questionnaires via Amazon's Mechanical Turk. An item response theory (IRT) approach was used to test differential item functioning (DIF) of the English and Spanish HRS. We also examined convergent validity of each language version with other HD. Initial comparisons revealed that hoarding symptoms were elevated in the Spanish-speaking sample compared to the English-speaking sample. DIF tests flagged the clutter item for potential bias (McFadden's β=.069), but closer examination revealed that the impact was negligible. The Spanish HRS was significantly linked with other hoarding measures (Saving Inventory-Revised: β=.497, p<.001; Obsessive-Compulsive Inventory-Revised-Hoarding Subscale: β=.329, p=.008), controlling for mood, anxiety, stress, and non-hoarding OCD symptoms. However, the Spanish HRS was not significantly associated with Clutter Image Rating scores. Findings supported the utility of the HRS to measure of HD symptoms in Spanish speakers, though cross-linguistic assessment of clutter and the applicability of clinical cutoffs with Spanish-speaking samples merits further study.

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
The world has experienced pandemics worse than the coronavirus disease 2019 (COVID-19). However, the global effect of this pandemic has been overwhelming. Billions of people are in lockdown and also have easy access to information owing to easy and cheap internet connectivity and electronic media. However, information overload during the current COVID-19 pandemic has posed a set of challenges that were not encountered before. There is an ‘infodemic’ in which false news, conspiracy theories, magical cures, and racist news are being shared at an alarming rate, with the potential to increase anxiety and stress and even lead to loss of life. This review highlights some of these challenges and suggests general measures to avoid information overload and infodemic in the connected world of 21st century.

Abstract
Objectives: Despite the inclusion of hoarding disorder (HD) in the DSM-5, there is little epidemiological data on hoarding from low and middle-income countries. This study, the first from India, examines the prevalence and correlates of HD among primary care patients in the state of Kerala, India. Methods: To assess correlates, the Hoarding Rating Scale-Interview (HRS-I) and other structured instruments were administered to 7,555 subjects selected by stratified random sampling from 71 primary health centers. Results: The prevalence of HD was 1.02% (95%CI 0.8-1.3). Those with HD were more likely to be older and live alone. In the binary logistic regression analysis, after controlling for significant sociodemographic variables, subjects with HD had a higher odds of reporting chronic illness, depression, anxiety disorder, alcohol abuse, and tobacco dependence. Subjects with HD had significantly higher disability scores than unaffected individuals. Conclusion: Although HD is not uncommon in India, this disorder is rarely reported in specialty settings in India, which suggests that awareness and detection should be improved, considering the co-occurring negative correlates and disability among affected individuals.

Abstract
OBJECTIVES Hoarding disorder in older adults often develops in the context of co-occurring psychosocial maladies, and treatment response tends to be suboptimal. This preliminary investigation explored several ageing-related factors and their relationship to hoarding symptom severity (HSS), and examined treatment response to 15 sessions of cognitive behavioural therapy (CBT) with in-home support. METHODS Twenty-nine participants (Mage = 67) completed self-report questionnaires measuring HSS, self-control, indecisiveness, depression, loneliness, social support and boredom, before (T1) and after (T2) treatment. RESULTS At T1, HSS was associated marginally with loneliness and significantly with all other variables, except social support. At T2, HSS and depression decreased significantly and only boredom and self-control remained associated with HSS. Attrition rates were high, and those with low social support were more likely to discontinue treatment prematurely. CONCLUSIONS Increasing social support may improve treatment retention, and pre-emptively reducing sources of boredom and increasing self-control during treatment might improve outcomes for older adults with hoarding disorder.

Abstract
Previous studies have reported clinical characteristics of hoarding disorder (HD), such as early onset, a chronic course, familiality, high unmarried rate, and high rates of comorbidities. However, clinical research targeting Japanese HD patients has been very limited. As a result, there is a low recognition of HD in Japan, leading to insufficient evaluation and treatment of Japanese HD patients. The aim of the current study was to delineate the clinical characteristics of Japanese HD patients. Thirty HD patients, 20 obsessive-compulsive disorder (OCD) patients, and 21 normal controls (NC) were targeted in this study. The HD group had a tendency toward higher familiality, earlier onset, and longer disease duration compared to the OCD group. In addition, the HD group showed a significantly higher unmarried rate than the NC group. The top two comorbidities in the HD group were major depressive disorder (56.7%) and attention-deficit/hyperactivity disorder (26.7%). The HD group had significantly higher scores on hoarding rating scales and lower scores on the Global Assessment of Functioning Scale than the other two groups. The current study showed a clinical trend in Japanese HD patients similar to previous studies in various countries, suggesting that HD may be a universal disease with consistent clinical symptoms.

Abstract
Currently there is uncertainty concerning the prevalence of Hoarding Disorder (HD) due to methodological issues in the evidence base. Estimates have widely ranged from between 1.5% and 6% of the general population. This systematic review and meta-analysis therefore aimed to summarise and reliably estimate the prevalence of HD by employing strict inclusion criteria and using studies with sufficiently large samples. A systematic literature search was conducted to identify all relevant prevalence studies. Inclusion criteria were studies that reported working age adult HD prevalence rates and had sample sizes of at least 1009 participants. Eleven studies met criteria (n = 53,378), had low risk of bias and were originally based in developed countries. A random effects meta-analysis was then conducted, with subgroup moderator analysis and meta-regression. The pooled estimated prevalence for HD was 2.5% (CI 1.7-3.6%) and subgroup analyses revealed that prevalence rates were similar for both males and females. Guidance on the manner in which HD is assessed in future prevalence studies is provided and the clinical implications of the results discussed.

Abstract
Hoarding disorder (HD) is a newly listed disease in the new category of Obsessive-Compulsive and Related Disorders in the DSM-5. Patients with HD find it difficult to discard possessions regardless of their actual value and to organize those things. As a result, the possessions overflow the living space and hinder living functions. Though the hoarding symptom had been regarded as a subtype of obsessive-compulsive disorder (OCD) to date, recent studies have revealed many differences in clinical characteristics, including onset, course, degree of insight, and treatment responses, between hoarding and other subtypes. Moreover, several neuroimaging studies have found specific changes of brain structure and function in OCD patients with hoarding symptoms compared to patients with non-hoarding OCD. Meanwhile, strategies for treatment of HD have not been standardized. At present, psychological treatment using cognitive behavioral therapy techniques has a certain effect. In this review, we outline the pathophysiology and treatment of HD.
