Obsessive-compulsive disorder and family accommodation: A 3-year follow-up.

The present study assessed 3-year maintenance of family accommodation (FA) reduction in a sample from a randomized clinical trial that assessed the impact of 12 sessions of cognitive-behavioral group therapy (CBGT) for obsessive-compulsive disorder (OCD), with the involvement of family members in two sessions. Of the 46 original pairs of patients/family members, 35 were assessed at 3 years. Demographic and clinical characteristics remained similar. Post-CBGT improvement of OCD symptoms remained significant; FA reduced 39% after the therapy and 51% at follow-up. FA reduction remained over time, underscoring the importance of permanently assessing FA and involving family members when treating OCD.

Impact of cognitive-behavioral group therapy for obsessive-compulsive disorder on family accommodation: A randomized clinical trial.

The aim of this study was to assess the impact of cognitive-behavioral group therapy (CBGT) with the brief involvement of family members on family accommodation and to identify predictors of family accommodation reduction (patient and family member characteristics). This randomized clinical trial assessed 98 pairs of patients with obsessive-compulsive disorder (OCD) and their family members: 52 (53.1%) were allocated to the intervention group (12 CBGT sessions - two with the family member), and 46 (46.9%) to a waiting list (control group). Symptom severity and family accommodation were assessed before and after CBGT. There was significant improvement of OCD symptoms and family accommodation scores after CBGT in the intervention group vs. the control group. The following variables were significant predictors of family accommodation reduction after multivariate analysis: patient characteristics - absence of comorbid unipolar disorder, lower obsession score, and higher education level; family member characteristics - higher hoarding score. The model explained 47.2% of the variance in family accommodation scores after treatment. CBGT for patients with OCD and the brief involvement of family members contributed to reduce family accommodation. Both patient and family member characteristics were predictors of family accommodation reduction. This finding can help qualify CBGT protocols.

NEUROPSYCHOLOGICAL PREDICTORS OF TREATMENT RESPONSE TO COGNITIVE BEHAVIORAL GROUP THERAPY IN OBSESSIVE-COMPULSIVE DISORDER.

BACKGROUND: The available research on the relationship between neuropsychological functioning and the therapeutic outcome of obsessive-compulsive disorder (OCD) has yielded inconsistent results. In this study, our aim was twofold. First, we sought to evaluate the effects of cognitive behavioral group therapy (CBGT) on neurocognitive functions in OCD patients. Second, we assessed the viability of neuropsychological test performance as a predictor of treatment response to CBGT. METHODS: One hundred fifty carefully screened OCD patients were randomized to receive either 12-week CBGT (n = 75) or to remain on a waiting list (WL; n = 75) for the corresponding time. Forty-seven participants dropped out of the study, leaving 103 participants that were included in the analysis (CBGT, n = 61; WL, n = 42). Participants had several neuropsychological domains evaluated both at baseline and at end-point. RESULTS: A significant difference in obsessive-compulsive, anxiety, and depression symptoms was observed between treated patients and controls favoring the CBGT group, but no significant differences were found on neuropsychological measures after 3 months of CBGT. In addition, there were no differences between treatment responders and nonresponders on all neuropsychological outcome measures. Employing a conservative alpha, neuropsychological test performance did not predict CBGT treatment response. CONCLUSIONS: Although the CBGT group demonstrated significant improvement in OCD symptoms, no significant difference was found on all neuropsychological domains, and test performance did not predict treatment response.

Family Accommodation Scale for Obsessive-Compulsive Disorder-Interviewer-Rated (FAS-IR), Brazilian Portuguese version: internal consistency, reliability, and exploratory factor analysis.

OBJECTIVE: To examine the psychometric properties of the Brazilian Portuguese version of the Family Accommodation Scale for Obsessive-Compulsive Disorder-Interviewer-Rated (FAS-IR). METHOD: A total of 114 family members of patients with obsessive-compulsive disorder (OCD) were assessed. The following analyses of the FAS-IR were carried out: internal consistency, inter-rater and test-retest reliability, and exploratory factor analysis. RESULTS: The Brazilian Portuguese version of the FAS-IR showed excellent inter-rater reliability (intraclass correlation coefficient [ICC]=0.94) and acceptable test-retest reliability (ICC=0.77), with no significant differences in FAS-IR scores. Factor analysis produced three factors for the scale. However, factor loadings were not well defined within each factor, and the factors did not have distinct constructs. Thus, a global analysis approach was chosen, revealing good internal consistency of the scale as a whole (Cronbach's α=0.805). CONCLUSIONS: The Brazilian Portuguese FAS-IR showed sound psychometric properties for the evaluation of family accommodation, and is, therefore, a reliable instrument for use in research and clinical practice.

Obsessive-compulsive symptoms and obsessive-compulsive disorder in adolescents: a population-based study

Objectives: To estimate the prevalence of obsessive-compulsive symptoms (OCS) and disorder (OCD) among adolescents and to describe OCD characteristics according to gender. Methods: Participants were selected by cluster sampling at seven high-schools in southern Brazil. In the first stage, 2,323 students were screened for OCS; in the second stage, adolescents scoring ≥ 21 on the OCI-R scale were individually interviewed. OCD diagnosis was established using a semi-structured interview (Schedule for Affective Disorders and Schizophrenia for School Aged Children: Present and Lifetime Version - K-SADS-PL). Results: The past-month estimated prevalence of OCS was 18.3%, and the point estimated prevalence of OCD, 3.3%. Girls showed higher scores (OCS: 24.8 vs. 14.4%; OCD: 4.9 vs. 1.4%; p < 0.001). Only 9.3% of OCD adolescents had been diagnosed and 6.7% received treatment. The most frequent/severe DY-BOCS dimensions were miscellaneous (86.7%; mean score 6.3±3.8) and symmetry (85.3%; 5.9±3.8). Female OCD adolescents predominantly showed depression (p = 0.032), and male adolescents, tic disorders (p = 0.006). Conclusions: OCD is underdiagnosed in adolescents, and few are treated. Future studies should investigate the relationship between OCS and the onset of OCD. .

Patient and family factors associated with family accommodation in obsessive-compulsive disorder.

AIM: Obsessive-compulsive disorder (OCD) impacts family functioning as family members modify their personal and family routines, participate in rituals, and provide reassurance. These behaviors have been identified as family accommodation (FA), a phenomenon that, if ignored, may facilitate OCD symptoms and lead to poorer prognosis. Because FA has been recognized as a predictor of treatment outcome, we examined the prevalence of FA and identified patient and family sociodemographic and clinical variables associated with FA in an outpatient sample. METHODS: The study comprised 228 subjects, namely, 114 patients with OCD and 114 family members, assessed before the patients entered a 12-session cognitive behavioral group therapy program. A multivariate linear regression model was used to control for confounding factors and to evaluate variables independently associated with FA. FA was evaluated using the Family Accommodation Scale for Obsessive-Compulsive Disorder-Interviewer Rated. RESULTS: FA was found to be highly prevalent among family members. Two patient factors positively associated with FA were OCD severity as measured by the Clinical Global Impressions Scale and higher scores on the Obsessions dimension of the Obsessive-Compulsive Inventory-Revised. Family members' characteristics that were positively associated with FA were higher scores on the Obsessive-Compulsive Inventory - Revised hoarding subscale and being the patient's spouse. CONCLUSION: Our findings suggest that the early identification of patients and family members who could benefit from interventions aimed at reducing FA could improve treatment outcomes.

Quality of life in adolescents with obsessive-compulsive disorder

Objective: To compare adolescents with and without obsessive-compulsive disorder (OCD) with regard to quality of life and to investigate the association between quality of life and clinical characteristics. Methods: Participants were recruited from an epidemiological study conducted at high schools in the city of Porto Alegre, southern Brazil. The sample comprised 75 adolescents with OCD and 150 without the disorder, aged between 14 and 18 years. Participants were assessed using the following instruments: Schedule for Affective Disorders and Schizophrenia for School Aged Children - Present and Lifetime Version (K-SADS-PL), Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), World Health Organization Quality of Life Assessment - Abbreviated Version (WHOQOL-BREF), Beck Anxiety Inventory (BAI), and Beck Depressive Inventory - II (BDI-II). Results: The two groups showed significant differences in relation to depression symptoms, anxiety symptoms, and quality of life (all domains), with a poorer performance among adolescents with OCD when compared to those without the disorder. Stepwise regression analysis revealed a significant association between BDI-II scores and quality of life, in all domains. Conclusions: Our findings suggest that adolescents with OCD, especially those with depression symptoms, have a poorer quality of life when compared with adolescents without OCD. .

Psychometric properties of the Brazilian version of the Obsessive Beliefs Questionnaire (OBQ-44).

The present study was designed to assess the psychometric properties of the Brazilian version of the Obsessive Beliefs Questionnaire (OBQ-44) in 104 patients with obsessive compulsive disorder (OCD) at the Hospital de Clínicas de Porto Alegre. The secondary objective was to ascertain whether a decline in OBQ-44 scores occurs after cognitive-behavioral group therapy (CBGT). Factor analysis identified three dysfunctional belief domains from the original scale. Internal consistency and reproducibility were very good and good, respectively. Sensitivity to treatment change (cognitive-behavioral group therapy) was good, and pre-post intervention standardized effect sizes (Cohen's d) were strong. The OBQ-44 plays an important role in this setting; as a user-friendly, self-administered instrument that lists the most common dysfunctional beliefs of OCD patients, it enables healthcare providers to assess whether their patients' beliefs change after treatment.

Towards a post-traumatic subtype of obsessive-compulsive disorder.

We evaluated whether traumatic events are associated with a distinctive pattern of socio-demographic and clinical features of obsessive-compulsive disorder (OCD). We compared socio-demographic and clinical features of 106 patients developing OCD after post-traumatic stress disorder (PTSD; termed post-traumatic OCD), 41 patients developing OCD before PTSD (pre-traumatic OCD), and 810 OCD patients without any history of PTSD (non-traumatic OCD) using multinomial logistic regression analysis. A later age at onset of OCD, self-mutilation disorder, history of suicide plans, panic disorder with agoraphobia, and compulsive buying disorder were independently related to post-traumatic OCD. In contrast, earlier age at OCD onset, alcohol-related disorders, contamination-washing symptoms, and self-mutilation disorder were all independently associated with pre-traumatic OCD. In addition, patients with post-traumatic OCD without a previous history of obsessive-compulsive symptoms (OCS) showed lower educational levels, greater rates of contamination-washing symptoms, and more severe miscellaneous symptoms as compared to post-traumatic OCD patients with a history of OCS.

Skin picking and trichotillomania in adults with obsessive-compulsive disorder.

The objective of this study was to compare patients with obsessive-compulsive disorder (OCD) associated with pathologic skin picking (PSP) and/or trichotillomania, and patients with OCD without such comorbidities, for demographic and clinical characteristics. We assessed 901 individuals with a primary diagnosis of OCD, using the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) Axis I disorders. Diagnoses of PSP and trichotillomania were made in 16.3% and 4.9% of the sample, respectively. After the logistic regression analysis, the following factors retained an association with OCD-PSP/trichotillomania: younger (odds ratio [OR] = 0.979; P = .047), younger at the onset of compulsive symptoms (OR = 0.941; P = .007), woman (OR = 2.538; P < .001), with a higher level of education (OR = 1.055; P = .025), and with comorbid body dysmorphic disorder (OR = 2.363; P = .004). These findings support the idea that OCD accompanied by PSP/trichotillomania characterizes a specific subgroup.

Translation and adaptation into Brazilian Portuguese of the Obsessional Beliefs Questionnaire (OBQ-44).

INTRODUCTION: The Obsessional Beliefs Questionnaire (OBQ-44) is a self-administered instrument comprised of 44 items, designed to assess the beliefs of patients with obsessive compulsive disorder (OCD). The objective of this study was to describe the process of translation and adaption of the questionnaire into Brazilian Portuguese. METHOD: For the translation and adaptation of the OBQ-44, we first obtained authorization from the authors of the original scale to use the instrument. Subsequently, the scale was independently translated from English into Brazilian Portuguese by two health professionals with proficiency in English. Following comparison of the two translations, a preliminary version was obtained and tried out on a sample of 20 patients with a primary diagnosis of OCD. This pretest aimed to assess the patients' understanding of the items and to make any necessary language adaptations. Then, the scale was independently back-translated by two psychiatrists, also with proficiency in English. Following comparison of the two back-translations, a final version in English was developed; this version was evaluated and approved by the authors of the original instrument. RESULTS: The Brazilian Portuguese version of the OBQ-44, after the process of translation and adaptation here described, showed to be of easy interpretation by patients with different educational levels. The instrument can therefore be used to assess patients from different Brazilian socioeconomic contexts. CONCLUSION: OBQ-44 is a self-administered instrument of easy application. Therefore, it can be useful in the identification of dysfunctional beliefs in OCD patients, contributing toward a better understanding of the role played by such beliefs in the onset and maintenance of the disorder.

INTRODUÇÃO: O Obsessional Beliefs Questionnaire (OBQ-44) é um instrumento autorrespondido composto por 44 itens que avaliam as crenças de pacientes com transtorno obsessivo-compulsivo (TOC). O objetivo do presente estudo foi descrever o processo de tradução e adaptação da referida escala para o português do Brasil. MÉTODO: Para o processo de tradução e adaptação do OBQ-44, primeiramente foi obtida licença de uso da escala junto aos autores do instrumento original. Em seguida, a escala foi traduzida de inglês para português brasileiro de forma independente por dois profissionais de saúde com fluência em inglês. Comparando-se as duas escalas traduzidas, obteve-se uma versão preliminar, que foi aplicada a uma amostra de 20 pacientes com diagnóstico principal de TOC, visando observar sua compreensão e realizar adaptações de linguagem. A seguir, a escala foi retrotraduzida de forma independente por dois psiquiatras, também fluentes na língua inglesa. Comparadas as duas retrotraduções, gerou-se uma versão final em língua inglesa; esta versão foi avaliada e aprovada pelos autores do instrumento original. RESULTADOS: A versão em português do Brasil do OBQ-44, após sua tradução e adaptação, demonstrou ser de fácil compreensão por parte de pacientes de diferentes níveis educacionais. Portanto, a escala pode ser utilizada em pacientes das diversas classes econômicas e sociais que caracterizam o Brasil. CONCLUSÃO: O OBQ-44, por ser um instrumento autoaplicável e de fácil compreensão, pode ser útil na identificação de crenças disfuncionais em pacientes com TOC, auxiliando na compreensão do papel dessas crenças na origem e manutenção do transtorno.

Psychometric properties of the Brazilian Portuguese version of the Obsessive-Compulsive Inventory - Revised (OCI-R).

OBJECTIVE: The present study was designed to evaluate the psychometric properties of the Brazilian Portuguese version of the Obsessive-Compulsive Inventory - Revised. METHOD: The Obsessive-Compulsive Inventory - Revised was administered to a total of 260 participants: a clinical sample of 130 patients with anxiety disorders (64 with a diagnosis of obsessive-compulsive disorder patients, 33 diagnosed with social phobia, and 33 with panic disorder) and a sample of 130 non-clinical subjects. RESULTS: The findings indicate that the Obsessive-Compulsive Inventory - Revised is a valid measure for identifying and assessing the severity of the six symptom subtypes in obsessive-compulsive disorder. The original factor structure of the instrument was replicated in an exploratory factor analysis. Test-retest reliability was examined using data from 64 obsessive-compulsive disorder patients who completed the inventory on two different occasions. In each sample, the overall and subscale scores showed moderate to good internal consistency, good convergent and divergent validity, and sensitivity to changes resulting from cognitive-behavioral group therapy. CONCLUSION: Our findings indicate that the Brazilian Portuguese version of the Obsessive-Compulsive Inventory - Revised retains the psychometric properties of its original version and the Spanish, German and Icelandic versions.

Cognitive dysfunction in post-traumatic obsessive-compulsive disorder.

OBJECTIVE: To investigate whether patients who develop obsessive-compulsive disorder (OCD) after posttraumatic stress disorder, i.e. post-traumatic OCD (PsT-OCD), display a distinctive neurocognitive pattern of dysfunction. METHODS: Patients with PsT-OCD (n = 16), pre-traumatic OCD (PrT-OCD) (n = 18), non-traumatic OCD (NonT-OCD) (n = 67) and healthy controls (n = 17) had their performance compared on the following neuropsychological tests: the Wisconsin Card Sorting Test, the Iowa Gambling Task, the Wechsler Memory Scale Logical Memory, the Brief Visual Memory Test - Revised, and the Wechsler Abbreviated Scale for Intelligence. RESULTS: Patients with OCD, as a group, were characterized by poor set-shifting abilities and impaired verbal and visuospatial memories. Impaired set-shifting abilities were found to correlate with the severity of obsessive-compulsive symptoms in all groups of patients with OCD, with the exception of PsT-OCD. Only patients with PsT-OCD were characterized by impaired visuospatial recognition, which was found to correlate with poor set-shifting abilities in this particular group of patients, but not in individuals with other types of OCD or in healthy controls. CONCLUSIONS: Our study suggests that PsT-OCD is associated with a distinctive pattern of neurocognitive dysfunction, thus providing support for a different subtype of OCD.

Comorbid major depression in obsessive-compulsive disorder patients.

Although major depressive disorder (MDD) has been consistently considered the most frequent complication of obsessive-compulsive disorder (OCD), little is known about the clinical characteristics of patients with both disorders. This study assessed 815 Brazilian OCD patients using a comprehensive psychiatric evaluation. Clinical and demographic variables, including OCD symptom dimensions, were compared among OCD patients with and without MDD. Our findings showed that prevalence rates of current MDD (32%) and lifetime MDD (67.5%) were similar for both sexes in this study. In addition, patients with comorbid MDD had higher severity scores of OCD symptoms. There was no preferential association of MDD with any particular OCD symptom dimension. This study supports the notion that depressed OCD patients present more severe general psychopathology.
