Assessment of Critical Health and Safety Risks in Homes where Hoarding is Prevalent.

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.

Postpartum Thoughts of Infant-Related Harm and Obsessive-Compulsive Disorder: Relation to Maternal Physical Aggression Toward the Infant.

Unwanted intrusive thoughts (UITs) of intentional infant-related harm are ubiquitous among new mothers and frequently raise concerns about infant safety. The purpose of this research was to assess the relation of new mothers' UITs of intentional, infant-related harm and obsessive-compulsive disorder (OCD) with maternal aggression toward the infant and to document the prevalence of maternal aggression toward the infant. From a prospective, province-wide, unselected sample of 763 English-speaking postpartum women, a total of 388 participants provided data for this portion of the research.

High Prevalence and Incidence of Obsessive-Compulsive Disorder Among Women Across Pregnancy and the Postpartum.

During the perinatal period, women are at an increased risk for the onset/exacerbation of obsessive-compulsive disorder (OCD) and may experience perinatal-specific obsessions and/or compulsions. Past research has provided preliminary findings regarding the prevalence of OCD in the perinatal period but has often reported limited metrics and ignored perinatal specific symptoms. This research aimed to assess the prevalence and incidence of maternal OCD between the third trimester in pregnancy and 6 months postpartum.

How well do hoarding research samples represent cases that rise to community attention?

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.

How can cities tackle hoarding? Examining an intervention program bringing together fire and health authorities in Vancouver.

Hoarded homes can pose a threat to public safety, with heightened risks of fire hazards, pest infestations and noxious odours in both the home and neighbouring dwellings. Communities across North America are responding to these public safety concerns through a harm reduction approach. This descriptive study explores the implementation and outcomes of the City of Vancouver's approach involving a partnership between fire prevention and public health.

Saving inventory - Revised: Psychometric performance across the lifespan.

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.

Maternal unwanted and intrusive thoughts of infant-related harm, obsessive-compulsive disorder and depression in the perinatal period: study protocol.

Background: Unwanted, intrusive thoughts of harm-related to the infant are reported by the vast majority of new mothers, with half of all new mothers reporting unwanted, intrusive thoughts of harming their infant on purpose. Thoughts of intentional harm, in particular, are distressing to women, their partners and the people who care for them. While maternal, unwanted and intrusive thoughts of infant-related harm are known to be associated with obsessive compulsive disorder (OCD) and depression, preliminary evidence suggests that they are not associated with an increased risk of harm to infants.

Acceptance of cravings: how smoking cessation experiences affect craving beliefs.

Metacognitive models theorize that more negative appraisals of craving-related thoughts and feelings, and greater efforts to avoid or control these experiences, exacerbate suffering and increase chances the person will use substances to obtain relief. Thus far, little research has examined how attempts to quit smoking influence the way people perceive and respond to cravings. As part of a larger study, 176 adult smokers interested in quitting participated in two lab sessions, four days apart.

Review of cognitive performance in hoarding disorder.

Hoarding disorder is characterized by extreme difficulty letting go of objects other people would routinely discard or give away, such that the home becomes dysfunctionally cluttered with possessions. Specific cognitive processes, such as decision-making, categorization, and attention, have been hypothesized to contribute to the overvaluing of objects. This review synthesizes the evidence related to those propositions and other executive functioning processes that have received research attention.

Brief psycho-education affects circadian variability in nicotine craving during cessation.

Background: Nicotine cravings are a key target of smoking cessation interventions. Cravings demonstrate circadian variation during abstinence, often peaking during the morning and evening hours. Although some research has also shown diurnal variation in the efficacy of nicotine replacement medications, little research has examined how brief psychosocial interventions affect temporal patterns of craving during abstinence.

Development and initial validation of the White Bear Suppression Inventory (Smoking Version).

Introduction: Thought suppression can produce a paradoxical rebound in unwanted cognition. Although interest in the role of suppression in nicotine dependence is growing quickly, a validated measure specifically assessing suppression of smoking-related thoughts does not exist. The present study describes the development of the White Bear Suppression Inventory-Smoking Version (WBSI-S).

Social anxiety among East Asians in North America: East Asian socialization or the challenge of acculturation?

North American research has consistently reported higher social anxiety among people of Asian heritage compared to people of Western heritage. The present study used a cross-national sample of 692 university students to explore explanatory hypotheses using planned contrasts of group differences in social anxiety and related variables. The East Asian socialization hypothesis proposed social anxiety would show a linear relation corresponding to the degree of exposure to East Asian cultural norms.

Mechanisms of symptom reduction in treatment for obsessions.

Objective: We explored the dynamic relationship between cognition and obsession severity during 2 different treatments for primary obsessions, examining evidence for the hypothesis that symptom reduction would be mediated by appraisals about the meaning of unwanted intrusive thoughts.

Method: Data from a recent randomized controlled trial were analyzed with traditional mediation analyses and latent difference scores. The trial had compared cognitive behavioral therapy and stress management training among 73 patients with primary obsessions.

Treatment of obsessions: a randomized controlled trial.

This study tested Rachman's cognitive behavioral method for treating obsessions not accompanied by prominent overt compulsions. The cognitive behavioral treatment was compared to waitlist control and an active and credible comparison of stress management training (SMT). Of the 73 adults who were randomized, 67 completed treatment, and 58 were available for one-year follow-up.

Effects of suppression and appraisals on thought frequency and distress.

Cognitive theories of obsessions highlight appraisals of personal significance and thought suppression in the development and maintenance of intrusive thoughts. The current study examined the role of personal significance within the context of a thought suppression paradigm. The primary aim was to examine whether suppression would have differential effects for target thoughts appraised as personally meaningful versus relatively unimportant.

Vulnerability factors in OCD symptoms: cross-cultural comparisons between Turkish and Canadian samples.

Recent findings have suggested some potential psychological vulnerability factors for development of obsessive-compulsive (OC) symptoms, including cognitive factors of appraisal and thought control, religiosity, self-esteem and personality characteristics such as neuroticism. Studies demonstrating these associations usually come from Western cultures, but there may be cultural differences relevant to these vulnerability factors and OC symptoms. The present study examined the relationship between putative vulnerability factors and OC symptoms by comparing non-clinical samples from Turkey and Canada, two countries with quite different cultural characteristics.

OCD cognitions and symptoms in different religious contexts.

Religious themes commonly feature in obsessions. Some theorists view religiosity as a potential risk factor, due to the hypothesized influence of religious acculturation on appraisals of unwanted intrusive thoughts. Several studies revealed that the relationship between religiosity and some OCD cognitions might change among various religions, possibly because of the differences in religious doctrines and teachings.

New mothers' thoughts of harm related to the newborn.

There are few published studies of new mothers' experiences of intrusive thoughts of harm related to the newborn. Evidence-based information about the normal phenomenology of intrusive thoughts of harm related to the newborn is needed to facilitate appropriate clinical decision-making. The objective of this project was to assess the phenomenology, prevalence, correlates, and behavioural sequelae of maternal thoughts of harm related to the newborn.

Appraisals of obsessional thoughts in normal samples.

Cognitive theories of obsessive-compulsive disorder (OCD) posit that appraisals about the significance of thoughts are critical in the development and persistence of obsessions. Rachman [(1997). A cognitive theory of obsessions.

Fear of childbirth and obstetrical events as predictors of postnatal symptoms of depression and post-traumatic stress disorder.

This prospective study examined psychological and obstetrical predictors of enduring postpartum symptoms of depression and post-traumatic stress disorder. Contrary to prediction, prenatal fear of childbirth did not significantly predict symptoms of depression or post-traumatic stress disorder at one month postpartum, but anxiety sensitivity was an unexpected predictor that merits further investigation. Several obstetrical and neonatal variables significantly predicted symptoms of post-traumatic disorder, but not depression.

Cultural mediators of self-reported social anxiety.

East Asians generally endorse higher social anxiety than do Westerners. Widely used measures of social anxiety, however, may not account for different social values across cultures. Drawing from Korean (n=251) and Euro-Canadian (n=250) community samples, this study used a cross-sectional design to examine the relationship between ratings of social anxiety and beliefs and self-views typically found in East Asian cultures.

Implicit and explicit appraisals of the importance of intrusive thoughts.

To evaluate cognitive theories of obsessions, the current study experimentally manipulated appraisals of the importance of intrusive thoughts. Undergraduate students (N = 156) completed measures of obsessive-compulsive disorder (OCD) symptoms and beliefs and were primed with a list of commonly reported unwanted thoughts. Participants were then informed that unwanted thoughts are either (1) significant and indicative of their personal values, or (2) meaningless, or participants (3) received no instructions about unwanted thoughts.

Does threatening imagery sensitize distress during contaminant exposure?

Prominent models of fear focus on the role of cognition in the development and maintenance of maladaptive responses. Little research, however, has evaluated the impact of cognition on distress reduction. The current study uses an experimental design to examine the effect of different types of imagery (moving harm, static harm, and safety) on reduction of distress associated with a contaminating stimulus in a normal university sample.
