Mental Contamination in Obsessive-Compulsive Disorder: Associations With Contamination Symptoms and Treatment Response.

This study examined the relationships between CC and MC in a sample of individuals with elevated contamination symptoms (N = 88), half of whom met diagnostic criteria for OCD. Participants engaged in three sessions of exposure and response prevention (ERP) for CC and completed self-report measures and behavioral tasks assessing CC and MC at pretreatment, posttreatment, and follow-up. As hypothesized, at pretreatment, MC was positively associated with reactivity to physical contaminants, even after participants washed their hands. ERP for CC was associated with unique changes in CC and MC across self-report and behavioral measures, and greater pretreatment MC predicted greater posttreatment CC, though this effect was evident in only one of two CC measures. Additionally, specificity analyses indicated changes in MC were independent of changes in disgust propensity, a related construct. Pretreatment disgust propensity also predicted treatment outcome, though the addition of pretreatment disgust propensity as a covariate reduced the relationship between pretreatment MC and posttreatment CC to nonsignificance. Results suggest MC plays an important role in the manifestation and treatment of CC symptoms and may represent a manifestation of disgust proneness. Theoretical and clinical implications are discussed. PMID: 30661555 [PubMed - in process]

This article reviews the existing empirical literature on technology-supported interventions for hoarding behaviors. Such interventions include online self-help resources, videoconferencing and webcam-based individual and group treatment, “blended” face-to-face plus therapist assisted online programs, as well as virtual reality. Technology-based interventions may extend access to practitioners with expertise in hoarding, incorporate evidence-based strategies that are available anytime and from anywhere, facilitate more cost-effective services, allow for flexibility in scheduling, harness motivation, support eng...

__________ Psychiatric diagnosis ‘scientifically meaningless’ (Science Daily): “A new study, published in Psychiatry Research, has concluded that psychiatric diagnoses are scientifically worthless as tools to identify discrete mental health disorders. The study, led by researchers from the University of Liverpool, involved a detailed analysis of five key chapters of the latest edition of the widely used Diagnostic and Statistical Manual (DSM), on ‘schizophrenia’, ‘bipolar disorder’, ‘depressive disorders’, ‘anxiety disorders’ and ‘trauma-related disord...

The extent to which these relate to Obsessive-Compulsive Disorder (OCD) is unclear, despite anxiety being a prominent symptom of this disorder. The purpose of this analysis was to examine gastrointestinal symptoms in unmedicated, non-depressed adult OCD patients compared to age- a...

Abstract Homicide is the most serious and costly criminal offense and better forensic and criminological understanding of homicidal ideation as a potential psychobehavioral precursor to homicidal conduct is critical. Using data from the 2016 Nationwide Emergency Department Sample (NEDS) from the Healthcare Cost and Utilization Project (HCUP) distributed by the Agency for Healthcare Research and Quality (AHRQ), we found 64,910 cases of homicidal ideation among a sample of 25.6 + million-a prevalence of 0.25%. Numerous conditions conferred increased substantially the likelihood of homicidal ideation includ...

Abstract Cannabidiol (CBD) and Δ9-tetrahydrocannabinol (THC) are the most represented phytocannabinoids in Cannabis sativa plants. However, CBD may present with a different activity compared with the psychotomimetic THC. Most typically, CBD is reported to be used in some medical conditions, including chronic pain. Conversely, the main aim of this systematic review is to assess and summarise the available body of evidence relating to both efficacy and safety of CBD as a treatment for psychiatric disorders, alone and/or in combination with other treatments. Eligible studies included randomized controlled trial...
