Family accommodation in obsessive-compulsive disorder: An updated systematic review and meta-analysis.

Family accommodation might play a crucial role in obsessive-compulsive disorder (OCD). Previous systematic reviews on family accommodation in OCD have focused on specific populations or variables or are outdated. We conducted a preregistered systematic review and meta-analysis on family accommodation in adults, children, and adolescents with OCD (CRD42021264461). We searched PubMed, Scopus, and Web of Science using the keywords "family accommodation" and "obsessive-compulsive disorder. One hundred-eight studies involving 8928 individuals with OCD were included. Our results indicate that levels of family accommodation in OCD are moderate, that there is a significant positive correlation between family accommodation and OCD severity (r = 0.42), that baseline family accommodation does not predict pre- to post-treatment change in OCD severity (g = -0.03), and that family accommodation decreases as a result of both individual and family-focused cognitive behavioral therapy for OCD (g = 2.00 and g = 1.17, respectively). Our findings highlight the relevance of family accommodation in OCD and may help guide assessment and treatment.

Neuropsychological functioning and its correlates at 1 year follow-up of severe COVID-19.

BACKGROUND: Short-term cognitive impairment is associated with SARS-CoV-2 infection but the long-term impact is yet to be examined in detail. We aim to study the evolution of these symptoms in severe COVID-19 patients admitted to the intensive care unit (ICU) between April and December 2020 1 year after hospital discharge and to analyze its clinical correlates. METHOD: A total of 58 patients agreed to participate in the 6 months follow-up and 30 at 1 year after hospital discharge. Demographic, clinical and laboratory data were collected and a comprehensive neuropsychological battery including validated tests for the main cognitive domains was administered. To test the magnitude of neurocognitive sequelae, two standard deviations below normative group were considered. To compare the neuropsychological performance at 6 and 12 months follow-up we used repeated measures tests. Finally, regression analyses were performed to test the main effects of medical and psychological factors on multiple cognition. RESULTS: Almost half of the sample continued to have impaired performance on neuropsychological tests at 12 months follow-up. In comparison with the results obtained at 6 months, significant improvements were found in immediate recall (d = 0.49), delayed recall (d = 0.45), and inhibitory control (d = 0.53). Medical variables predicted cognitive performance at 6 months but not at 12 months follow-up, while anxiety and depression predicted cognitive deficits in the long-term. CONCLUSIONS: A generalised improvement was observed in severe COVID-19 patients at follow-up. This improvement was particularly notable in verbal memory and executive functioning. However, a considerable proportion of the sample continued to present deficits at 1 year follow-up.

Psychotropic medication use among adolescents participating in three randomized trials of DBT.

BACKGROUND: Frequently presenting with symptoms of mood or anxiety disorders, substance abuse or borderline personality disorder, suicidal and self-harming adolescents often are prescribed psychotropic medication. Though such treatment may be warranted, recurrent suicidal and self-harming behaviour is often linked to emotion dysregulation where pharmacological treatment has weak empirical support. There is a need for more clinical research into the frequency, type and rationale for pharmacological treatment in this group. In this secondary analysis of three randomized clinical trials of dialectical behaviour therapy for adolescents, we report on psychotropic medication use in the respective samples at the time of recruitment, compare use of psychotropic medication across trials and describe sample characteristics that may be associated with possible differences in psychotropic medication. FINDINGS: Trials were conducted in Norway, the US and Spain (labelled the Oslo, US and Barcelona samples). At baseline, 86% of the Barcelona sample, 67% of the US sample and 12% of the Oslo sample were taking at least one psychotropic medication with antidepressants as the most frequent, followed by antipsychotics (72%, 22% and 1.3% respectively) and mood stabilizers (14.2%, 16.2% and 0%). In the Oslo sample there was a significant association between receiving a diagnosis of major depression and the likelihood of receiving antidepressants, but no such association was found in the Barcelona and US samples. The overall 7-8 times higher proportion of participants in the US and Barcelona samples treated with psychotropic medication could only partially be explained by differences between the samples in diagnostic profiles, symptom severity or level of dysfunction. CONCLUSIONS: Highly prevalent in use among suicidal and self-harming adolescents with borderline features, psychotropic medication was still very unevenly prescribed across trials, differences not explained by differences in sample characteristics suggesting that current treatment practices are not fully empirically supported. We call for continued medical education and increased availability of evidence-based psychosocial interventions.

Cool Kids: Cognitive Behavioral Therapy in a Spanish Sample of Children and Adolescents with Anxiety Disorders.

Anxiety disorders (ADs) negatively impact functioning and life quality. Studies on cognitive behavioral therapy (CBT) have demonstrated its short- and long-term efficacy. Cool Kids (CK) is a 10-session CBT-based group program administered to participants with ADs aged 7-17 years and their parents, and it has demonstrated efficacy compared with control groups. This study analyzes the effectiveness of CK in a clinical cohort of Spanish children and adolescents with ADs. CK was offered to 57 patients with AD and their caregivers at the Hospital Clínic, Barcelona. In all global registered measures, the results demonstrated a reduction of symptoms and their interference in daily functioning. Moreover, a significant improvement was observed in participants who completed more sessions. Thus, CK reduced the severity of anxiety and its interference over individual and family functioning.

Vickybot, a Chatbot for Anxiety-Depressive Symptoms and Work-Related Burnout in Primary Care and Health Care Professionals: Development, Feasibility, and Potential Effectiveness Studies.

BACKGROUND: Many people attending primary care (PC) have anxiety-depressive symptoms and work-related burnout compounded by a lack of resources to meet their needs. The COVID-19 pandemic has exacerbated this problem, and digital tools have been proposed as a solution. OBJECTIVE: We aimed to present the development, feasibility, and potential effectiveness of Vickybot, a chatbot aimed at screening, monitoring, and reducing anxiety-depressive symptoms and work-related burnout, and detecting suicide risk in patients from PC and health care workers. METHODS: Healthy controls (HCs) tested Vickybot for reliability. For the simulation study, HCs used Vickybot for 2 weeks to simulate different clinical situations. For feasibility and effectiveness study, people consulting PC or health care workers with mental health problems used Vickybot for 1 month. Self-assessments for anxiety (Generalized Anxiety Disorder 7-item) and depression (Patient Health Questionnaire-9) symptoms and work-related burnout (based on the Maslach Burnout Inventory) were administered at baseline and every 2 weeks. Feasibility was determined from both subjective and objective user-engagement indicators (UEIs). Potential effectiveness was measured using paired 2-tailed t tests or Wilcoxon signed-rank test for changes in self-assessment scores. RESULTS: Overall, 40 HCs tested Vickybot simultaneously, and the data were reliably transmitted and registered. For simulation, 17 HCs (n=13, 76% female; mean age 36.5, SD 9.7 years) received 98.8% of the expected modules. Suicidal alerts were received correctly. For the feasibility and potential effectiveness study, 34 patients (15 from PC and 19 health care workers; 76% [26/34] female; mean age 35.3, SD 10.1 years) completed the first self-assessments, with 100% (34/34) presenting anxiety symptoms, 94% (32/34) depressive symptoms, and 65% (22/34) work-related burnout. In addition, 27% (9/34) of patients completed the second self-assessment after 2 weeks of use. No significant differences were found between the first and second self-assessments for anxiety (t8=1.000; P=.34) or depressive (t8=0.40; P=.70) symptoms. However, work-related burnout scores were moderately reduced (z=-2.07, P=.04, r=0.32). There was a nonsignificant trend toward a greater reduction in anxiety-depressive symptoms and work-related burnout with greater use of the chatbot. Furthermore, 9% (3/34) of patients activated the suicide alert, and the research team promptly intervened with successful outcomes. Vickybot showed high subjective UEI (acceptability, usability, and satisfaction), but low objective UEI (completion, adherence, compliance, and engagement). Vickybot was moderately feasible. CONCLUSIONS: The chatbot was useful in screening for the presence and severity of anxiety and depressive symptoms, and for detecting suicidal risk. Potential effectiveness was shown to reduce work-related burnout but not anxiety or depressive symptoms. Subjective perceptions of use contrasted with low objective-use metrics. Our results are promising but suggest the need to adapt and enhance the smartphone-based solution to improve engagement. A consensus on how to report UEIs and validate digital solutions, particularly for chatbots, is required.

Neuropsychological functioning in post-ICU patients after severe COVID-19 infection: The role of cognitive reserve.

BACKGROUND: Cognitive manifestations associated with Severe Acute Respiratory Syndrome by Coronavirus 2 (SARS-CoV-2) are yet to be described in the existing literature. The aim of this exploratory study is to analyze the impact of severe SARS-CoV-2 infection on neuropsychological performance 6 months following hospital discharge, and to identify which medical variables predict worse outcome. In this context, we study if cognitive reserve (CR) may play a protective role on cognitive impairment. METHODS: We enrolled a cohort of 102 severe SARS-CoV-2 survivors who had been admitted to the Intensive Care Unit (ICU) and were contacted 6-months post discharge. A total of 58 agreed to participate in this 6-month follow-up study. Patients with previously known cognitive impairment were excluded. Demographic, clinical and laboratory data were collected. Firstly, to test the magnitude of neurocognitive sequalae two standard deviations below normative group were considered. Secondly, to analyze the main effects of medical variables on cognition and the interaction with cognitive reserve, ANCOVA analyses were performed. RESULTS: 53.4% obtained a score below the cutoff point (<26) in the screening test MOCA. ICU variables including mechanical ventilation, days of sedation or high CRP days were related with cognition. Cognitive Reserve (CR) interacted with delirium (F â€‹= â€‹6.8, p â€‹= â€‹0.01) and sedation days (F â€‹= â€‹9.40, p â€‹= â€‹0.003) to predict verbal memory and interacted with high CRP to predict phonemic fluency (F â€‹= â€‹6.47, p â€‹= â€‹0.01). Finally, no differences in neuropsychological performance were found depending on subjective cognitive impairment (SCI). However, patients with SCI had a higher score in the HAD anxiety subscale (t â€‹= â€‹-2.2; p â€‹< â€‹0.05). CONCLUSIONS: In our cohort, cognitive dysfunction was related with ICU variables such as delirium, mechanical ventilation, and inflammation. CR modulated the impact of these variables on cognition. Cognitive complaints were related with anxiety but not with cognitive performance. Despite some limitations, including the need of replication of the findings with larger samples and control groups, our study suggests that high CR may be protective for severe COVID-19-related cognitive impairment.

Antidepressants overuse in primary care: Prescription trends between 2010 and 2019 in Catalonia.

INTRODUCTION: There has been an increase in the prescription of antidepressants (AD) in primary care (PC). However, it is unclear whether this was explained by a rise in diagnoses with an indication for AD. We investigated the changes in frequency and the variables associated with AD prescription in Catalonia, Spain. METHODS: We retrieved AD prescription, sociodemographic, and health-related data using individual electronic health records from a population-representative sample (N=947.698) attending PC between 2010 and 2019. Prescription of AD was calculated using DHD (Defined Daily Doses per 1000 inhabitants/day). We compared cumulative changes in DHD with cumulative changes in diagnoses with an indication for AD during the study period. We used Poisson regression to examine sociodemographic and health-related variables associated with AD prescription. RESULTS: Both AD prescription and mental health diagnoses with an indication for AD gradually increased. At the end of the study period, DHD of AD prescriptions and mental health diagnoses with an indication for AD reached cumulative increases of 404% and 49% respectively. Female sex (incidence rate ratio (IRR)=2.83), older age (IRR=25.43), and lower socio-economic status (IRR=1.35) were significantly associated with increased risk of being prescribed an AD. CONCLUSIONS: Our results from a large and representative cohort of patients confirm a steady increase of AD prescriptions that is not explained by a parallel increase in mental health diagnoses with an indication for AD. A trend on AD off-label and over-prescriptions in the PC system in Catalonia can be inferred from this dissociation.

PRimary carE digital Support ToOl in mental health (PRESTO): Design, development and study protocols.

BACKGROUND: About 30-50% of Primary Care (PC) users in Spain suffer mental health problems, mostly mild to moderate anxious and depressive symptoms, which account for 2% of Spain's total Gross domestic product and 50% of the costs associated to all mental disorders. Mobile health tools have demonstrated to cost-effectively reduce anxious and depressive symptoms while machine learning (ML) techniques have shown to accurately detect severe cases. The main aim of this project is to develop a comprehensive ML digital support platform (PRESTO) to cost-effectively screen, assess, triage, and provide personalized treatments for anxious and depressive symptoms in PC. METHODS: The project will be carried out in 3 complementary phases: First, a ML predictive severity model will be built based on all the cases referred to the PC mental health support programme during the last 5 years in Catalonia. Simultaneously, a smartphone app to monitor and deliver psychological interventions for anxiety and depressive symptoms will be developed and tested in a clinical trial. Finally, the ML models and the app will be integrated in a comprehensive decision-support platform (PRESTO) which will triage and assign to each patient a specific intervention based on individual personal and clinical characteristics. The effectiveness of PRESTO to reduce waiting times in receiving mental healthcare will be tested in a stepped-wedge cluster randomized controlled trial in 5 PC centres. DISCUSSION: PRESTO will offer timely and personalized cost-effective mental health treatment to people with mild to moderate anxious and depressive symptoms. This will result in a reduction of the burden of mental health problems in PC and on society as a whole. TRIAL REGISTRATION: The project and their clinical trials were registered in Clinical Trials.gov: NCT04559360 (September 2020).

Efficacy of an integrative approach for bipolar disorder: preliminary results from a randomized controlled trial.

BACKGROUND: Bipolar disorder (BD) represents one of the most therapeutically complex psychiatric disorders. The development of a feasible comprehensive psychological approach to complement pharmacotherapy to improve its clinical management is required. The main objective of the present randomized controlled trial (RCT) was to test the efficacy of a novel adjunctive treatment entitled integrative approach in patients with BD, including: psychoeducation, mindfulness training, and functional remediation. METHODS: This is a parallel two-armed, rater-blind RCT of an integrative approach plus treatment as usual (TAU), v. TAU alone. Participants were recruited at the Hospital Clinic of Barcelona and randomized to one of the two conditions. They were assessed at baseline and after finishing the intervention. The main outcome variable included changes in psychosocial functioning assessed through the Functioning Assessment Short Test (FAST). RESULTS: After finishing the treatment, the repeated-measures analyses revealed a significant group × time interaction in favor of the patients who received the integrative approach (n = 28) compared to the TAU group (n = 37) (Pillai's trace = 0.10; F(1,57) = 6.9; p = 0.01), improving the functional outcome. Significant effects were also found in two out of the six domains of the FAST, including the cognitive domain (Pillai's trace = 0.25; F(1,57) = 19.1; p < 0.001) and leisure time (Pillai's trace = 0.11; F(1,57) = 7.15; p = 0.01). Regarding the secondary outcomes, a significant group × time interaction in Hamilton Depression Rating Scale changes was detected (Pillai's trace = 0.08; F(1,62) = 5.6; p = 0.02). CONCLUSION: This preliminary study suggests that the integrative approach represents a promising cost-effective therapy to improve psychosocial functioning and residual depressive symptoms in patients suffering from BD.

Effects of an integrative approach to bipolar disorders combining psychoeducation, mindfulness-based cognitive therapy and functional remediation: study protocol for a randomized controlled trial / Efectos de un abordaje integral para el trastorno bipolar combinando la psicoeducación, terapia cognitiva basada en el mindfulness y rehabilitación funcional: protocolo para un ensayo clínico controlado y aleatorizado

INTRODUCTION: Bipolar disorder is related to a high level of personal, familial, social and economic burden. There is a need for feasible adjunctive psychological interventions easy to implement in clinical practice in order to enhance aspects that medication alone cannot achieve. This study aims to evaluate the impact of a 12-session adjunctive integrative program designed for patients with bipolar disorder. METHODS: This is a single-blind prospective, randomized controlled trial involving a total of 132 outpatients with bipolar disorder who will be recruited from the Hospital Clinic of Barcelona. All participants will be randomly assigned to two arms. All the patients will receive treatment as usual (TAU) but in addition the experimental group will receive an integrative approach consisting of 12-sessions of 90 min each in which contents of psychoeducation for patients have been combined with a session for family members, and complemented with aspects related to health promotion, mindfulness training, and strategies for cognitive and functional enhancement. The whole sample will be assessed at baseline, after completion (3-months) and at 12 months from baseline regarding demographic and clinical variables, psychosocial and cognitive functioning, wellbeing and quality of life. The primary outcome measure will be improvement in psychosocial functioning. CONCLUSIONS: If the integrative approach is effective, it would allow clinicians to cover different areas that may be affected by bipolar disorder, by means of a brief intervention that can therefore be easily generalized to clinical practice

INTRODUCCIÓN: El trastorno bipolar se asocia a un nivel elevado de carga personal, familiar, social y económica. Existe la necesidad de intervenciones psicológicas complementarias factibles y fáciles de implementar en la práctica clínica para mejorar aspectos que la medicación no consigue alcanzar. Este estudio tiene como objetivo evaluar el impacto de un programa integral de 12 sesiones complementario al tratamiento farmacológico para pacientes con trastorno bipolar. MÉTODOS: Ensayo clínico aleatorizado, controlado, a simple ciego. Serán reclutados del Hospital Clínic de Barcelona 132 pacientes ambulatorios diagnosticados de trastorno bipolar. Los participantes serán asignados aleatoriamente a dos grupos. Todos los pacientes recibirán el tratamiento habitual (TAU) pero, además, el grupo experimental recibirá un abordaje integral que consistirá en 12 sesiones de 90 min en las que se han combinado los contenidos de psicoeducación para pacientes con una sesión para familiares, complementándose con aspectos relacionados con la promoción de la salud, el entrenamiento en atención plena y estrategias para la potenciación cognitiva y funcional. La muestra completa será evaluada al inicio del estudio, a los 3 meses y a los 12 meses de seguimiento respecto a variables sociodemográficas y clínicas, de funcionamiento psicosocial y cognitivo, bienestar y calidad de vida. El principal resultado esperado será la mejoría en el funcionamiento psicosocial. CONCLUSIONES: Si el abordaje integral es efectivo, permitiría a los clínicos cubrir diferentes áreas que pueden verse afectadas por el trastorno bipolar, mediante una breve intervención que, por lo tanto, puede generalizarse fácilmente a la práctica clínica

Trastorno del vínculo en niños con trastorno del espectro alcohólico fetal / Attachment Disorder in Children with Fetal Alcohol Spectrum Disorder

INTRODUCCIÓN: El síndrome alcohólico fetal y los trastornos del espectro alcohólico fetal (TEAF) resultan de la exposición intrauterina al alcohol, y son las causas no heredables más comunes de discapacidad intelectual. Entre personas diagnosticadas de TEAF se ha identificado una mayor prevalencia de alteraciones físicas, cognitivas y conductuales, y mayor psicopatología en el niño, afectando a variables del temperamento que dificultan la creación de un vínculo seguro. Los niños con trastorno del vínculo presentan alteraciones conductuales, emocionales y de interacción social que aparecen asociados a la exposición de un patrón de cuidado caracterizado por negligencia, carencia social o maltrato durante la primera infancia. OBJETIVO: El objetivo del presente trabajo es aportar información sobre los trastornos del vínculo en población diagnosticada de un TEAF, a través de la revisión de la literatura existente y la presentación de dos casos clínicos. Por último, discutiremos sobre la intervención psicoterapéutica en este perfil clínico. MÉTODO: Estudio de casos clínicos, de dos niños con diagnóstico de TEAF y Trastorno del vínculo, atendidos en nuestro servicio de Psiquiatría y Psicología infanto-juvenil del Hospital Clínic de Barcelona. RESULTADO: Se expondrán las características clínicas y la evolución de los casos durante el tratamiento. CONCLUSIONES: Se propone un diagnóstico temprano y una intervención centrada en el vínculo que garantice un cuidador constante y sensible, involucrado emocionalmente y afectivamente disponible, y a partir de esta intervención, trabajar la sintomatología comórbida. No es posible generalizar los resultados debido a las limitaciones en la revisión y el número de casos

INTRODUCTION: Fetal alcohol syndrome and fetal alcohol spectrum disorders (FASD) result from intrauterine exposure to alcohol, and are the most common non-heritable causes of intellectual disability. Among people diagnosed with FASD, a higher prevalence of physical, cognitive and behavioral disorders, as well as more psychopathology have been identified in the child, affecting temperament variables that make it difficult to create a secure attachment. Children with attachment disorders show behavioral, emotional and social interaction problems that appear associated with exposure to patterns of care characterized by neglect, social deprivation or abuse during early childhood. OBJECTIVE: The aim of this work is to review the relationship between FASD and attachment disorders, through the review of the existing literature and the presentation of two clinical cases. Finally, we will discuss about the psychotherapeutic intervention in this clinical profile. METHOD: Clinical case study of 2 children with a diagnosis of FASD and attachment disorder, treated in our Child and Adolescent Clinical Psychiatry and Psychology Service at Hospital Clínic in Barcelona. RESULTS: The clinical characteristics and the evolution of the cases during the treatment will be presented. CONCLUSIONS: An early diagnosis and an intervention focused on attachment is proposed, providing a constant and sensitive caregiver, emotionally involved and affectively available, and after this, facilitate the work of comorbid symptoms. The results cannot be generalized due to review limitations and the number of cases
