RESUMO
Obsessive-compulsive disorder (OCD) is a debilitating psychiatric disorder. Worldwide, its prevalence is ~2% and its etiology is mostly unknown. Identifying biological factors contributing to OCD will elucidate underlying mechanisms and might contribute to improved treatment outcomes. Genomic studies of OCD are beginning to reveal long-sought risk loci, but >95% of the cases currently in analysis are of homogenous European ancestry. If not addressed, this Eurocentric bias will result in OCD genomic findings being more accurate for individuals of European ancestry than other ancestries, thereby contributing to health disparities in potential future applications of genomics. In this study protocol paper, we describe the Latin American Trans-ancestry INitiative for OCD genomics (LATINO, https://www.latinostudy.org). LATINO is a new network of investigators from across Latin America, the United States, and Canada who have begun to collect DNA and clinical data from 5000 richly phenotyped OCD cases of Latin American ancestry in a culturally sensitive and ethical manner. In this project, we will utilize trans-ancestry genomic analyses to accelerate the identification of OCD risk loci, fine-map putative causal variants, and improve the performance of polygenic risk scores in diverse populations. We will also capitalize on rich clinical data to examine the genetics of treatment response, biologically plausible OCD subtypes, and symptom dimensions. Additionally, LATINO will help elucidate the diversity of the clinical presentations of OCD across cultures through various trainings developed and offered in collaboration with Latin American investigators. We believe this study will advance the important goal of global mental health discovery and equity.
RESUMO
Family accommodation (e.g., reassurance, modifying routines, assisting avoidance) has not been explored among youth with misophonia but may have important clinical and intervention implications. We examined family accommodation in 102 children and adolescents with interview-confirmed misophonia and compared its frequency and content to family accommodation in 95 children and adolescents with anxiety disorders. Findings showed that family accommodation was ubiquitous in pediatric misophonia and may be even more frequent than in youth with anxiety disorders. Assisting the child, participating in misophonia-related behaviors, and modifying family routines were endorsed by more than 70% of parents of children with misophonia. Further, compared to parents of children with anxiety disorders, parents of children with misophonia more frequently reported child distress and anger when they did not accommodate. Family accommodation was moderately to strongly associated with misophonia severity even when accounting for co-occurring internalizing and externalizing symptoms and sociodemographic factors. This first study of family accommodation in pediatric misophonia suggests accommodation may be an important clinical feature. A notable study limitation is that the measure of misophonia did not delineate between adaptive versus maladaptive accommodations. Excessive and maladaptive accommodation may be one potential candidate to target in interventions when considered within a broader treatment plan. Importantly, adaptive accommodations should also be considered in day-to-day management if they improve functioning and quality of life.

OBJECTIVE: To examine the efficacy of the parent-led intervention Supportive Parenting for Anxious Childhood Emotions (SPACE) relative to a low-dose version of the protocol among children and adolescents with clinically significant anxiety and/or obsessive-compulsive disorder (OCD). METHOD: 68 youth (7-17) with anxiety/OCD and their parents were randomized to receive 12 weekly telehealth SPACE sessions (SPACE-Standard) or bibliotherapy plus 4 telehealth sessions over 12 weeks (SPACE-light). After screening, assessments were conducted via videoconferencing at baseline, post-treatment, and one-month follow-up. Independent evaluators were blind to treatment condition. RESULTS: Treatment condition did not predict whether a participant responded to the intervention (SPACE-Standard = 70%; SPACE-Light = 68%), nor was treatment condition a predictor of anxiety severity, parent-reported anxiety, or parent-/child-reported functional impairment at post-treatment or one-month follow-up. Youth in SPACE-Light self-reported higher post-treatment anxiety than youth in SPACE-standard, though this was no longer significant at one-month follow-up. Parent-reported family accommodation total change scores were associated with anxiety severity at post-treatment across both arms. CONCLUSION: This is the second randomized controlled trial (RCT) evaluating SPACE and provides further support for the efficacy of this intervention both in standard and low-dose formats. This study provides support for parent-led anxiety treatment targeting family accommodation as a primary mechanism of change and extends evidence of efficacy to a more clinically diverse sample.
