This article investigates the psychometric properties of the Revised Child Anxiety and Depression Scale (RCADS). A group of 704 adolescents completed the questionnaires in their classrooms. This study examines potential confirmatory factor analysis factor models of the RCADS as well as the relationships between the RCADS and the Screen for Child Anxiety Related Emotional Disorders-Revised (SCARED-R). A subsample of 595 adolescents also completed an anxiety questionnaire (Fear Survey Schedule for Children-Revised, FSSC-R) and a depression questionnaire (Center for Epidemiological Studies Depression Scale, CES-D). Confirmatory factor analysis of the RCADS suggests that the 6-factor model reasonably fits the data. All subscales were positively intercorrelated, with rs varying between .48 (generalized anxiety disorder-major depression disorder) and .65 (generalized anxiety disorder-social phobia/obsessive-compulsive disorder). The RCADS total score and all the RCADS scales were found to have good internal consistency (> .70). The correlations between the RCADS subscales and their SCARED-R counterparts are generally substantial. Convergent validity was found with the FSSC-R and the CES-D. The study included normal adolescents aged 10 to 19. Therefore, the findings cannot be extended to children under 10, nor to a clinical population. Altogether, the French version of the RCADS showed reasonable psychometric properties.

Abstract Introduction: The Patient Health Questionnaire-9 (PHQ-9) is a brief screening and diagnostic tool for depression. It has been used in research and clinical practice in primary care and other clinical and non-clinical settings. The PHQ-9 has not had its validity examined in psychiatric and psychological settings in Iran. Methods: A cross-sectional study was conducted to investigate the validation of the Farsi version of the PHQ-9. A convenience sample of 130 Iranian volunteer psychiatric outpatients was selected from psychiatric and psychological clinics. They completed the PHQ-9, the Patient Health Questionnaire-15 (PHQ-15), the World Health Organization-five Well-Being Index (WHO-5), and the short form of the Beck Depression Inventory-13 (BDI-13). Data were analyzed by descriptive statistics, Cronbach's α, Pearson correlation coefficient, principal component analysis, exploratory factor analysis, and confirmatory factor analysis. Results: Mean score of the PHQ-9 was 12.83 (standard deviation = 6.25), indicating moderately severe depression in the sample. Cronbach's α coefficient for PHQ-9 was 0.88, and one-week test-retest reliability 0.79. The PHQ-9 correlated 0.64 with PHQ-15, −0.35 with WHO-5, and 0.70 with BDI-13, indicating good construct and criterion-related validity. The results of the factor analysis of PHQ-9 items identified and confirmatory factor analysis confirmed a single factor labeled general depression. Conclusions: The PHQ-9 appears to have a unidimensional structure, adequate validity and reliability, and can be useful in epidemiological/research settings. Based on previous literature and on the present findings, the PHQ-9 may have applicability to other contexts in the studied population, but this needs to be confirmed by other studies.

El presente trabajo estudia la comorbilidad entre los usos problemático y adictivo de internet y los trastornos de ansiedad y depresión explorando la posible relación entre ambos fenómenos y las variables influyentes en la mayor o menor intensidad de dicha relación En el contexto de un programa de Cribado e Intervención Breve Digital dirigido a la prevención del uso problemático de internet (PiensaTIC) un total de 1.239 alumnos de enseñanzas secundarias ( 54% mujeres y 46% varones) de diez centros educativos de la provincia de Málaga cumplimentaron de forma on-line las escalas CIUS (Compulsive Internet Use Scale) para evaluar el uso problemático genérico de internet y el cuestionario YDQ (Young's Diagnostic Questionnaire) para evaluar el uso adictivo especifico de internet referido al uso de redes sociales y videojuegos. Asimismo contestaron las escalas GAD-2 (Generalized Anxiety Disorder-2) y PHQ-2 (Patient Health Questionnaire-2) diseñadas para realizar un cribado del riesgo de trastorno de ansiedad generalizada y de depresión. El uso compulsivo genérico de internet se asoció significativamente a un mayor riesgo de ansiedad y depresión siendo esta relación más evidente entre las alumnas que entre los alumnos. El uso intensivo de redes sociales (20 h semanales o más) está asociado a un mayor riesgo de ansiedad y depresión especialmente si cumple los criterios marcados por el YDQ como uso adictivo, no encontrándose diferencias de género en esta relación. No se encontró relación entre el uso adictivo de video juegos y el riesgo de ansiedad o depresión. Estos resultados sugieren la necesidad de evaluar de forma más exhaustiva la relación entre distintos trastornos psicopatológicos y los usos compulsivos y adictivos de internet como trastornos comórbidos que puedan cumplir los criterios de un trastorno de patología dual.

Abstract Purpose To identify the psychological impact of canceling cataract operations on patients during COVID-19 pandemic.Methods 99 participants aged from 59 years old who had their cataract surgeries postponed or as scheduled, were studied using the standardized patient health questionnaire (PHQ-9) and generalized anxiety disorder questionnaire (GAD-7) from April to June 2020 at Kowloon East Cataract Center, Tseung Kwan O Hospital, Hong Kong. ResultsNone of the patients who had the cataract surgeries rescheduled reached the cutoff score for major depression in PHQ-9, whereas for GAD-7, 5 patients had mild symptoms of anxiety, 1 had severe symptoms (p-value = 0.76). Conclusion There was no significant psychosocial impact of cancellation of cataract surgeries on patients.

Abstract Background Identifying mental health disorders, including body dysmorphic disorder (BDD), is important prior to rhinoplasty surgery; however, these disorders are underdiagnosed, and screening tools are underutilized in clinical settings. Objectives The authors sought to evaluate the correlation of a rhinoplasty outcomes tool (Standardized Cosmesis and Health Nasal Outcomes Survey [SCHNOS]) with psychiatric screening tools. Methods Patients presenting for rhinoplasty consultation were prospectively enrolled and administered mental health instruments to assess depression (Patient Health Questionnaire-9), anxiety (Generalized Anxiety Disorder-7), and BDD (BDD Questionnaire-Aesthetic Surgery [BDDQ-AS]) as well as the SCHNOS rhinoplasty outcomes scale. Convergent validity of SCHNOS scores with these mental health instruments was assessed as well as calculation of an optimal SCHNOS-C score to screen for BDD. Results A total 76 patients were enrolled in the study. The average SCHNOS-O score (standard deviation) was 46.1 (34.0) and the average SCHNOS-C score was 61.1 (27.0). Five (7%) patients screened positive for depression, and 24 (32%) patients screened positive for mild, 5 (7%) for moderate, and 4 (5%) for severe anxiety. Twenty-four (32%) patients screened positive for BDD by BDDQ-AS scores. SCHNOS-O and SCHNOS-C did not correlate with Patient Health Questionnaire-9 or Generalized Anxiety Disorder-7 scores; SCHNOS-C did correlate with BDDQ-AS. A score of 73 or greater on SCHNOS-C maximized the sensitivity and specificity of also screening positive for BDD with BDDQ-AS. This score correlated with a sensitivity of 62.5%, specificity of 80.8%, and number needed to diagnose of 2.3, meaning for every 2 patients with a score of ≥73 on SCHNOS-C, 1 will have a positive BDDQ-AS score. Conclusions SCHNOS-C correlates with BDDQ-AS and may help screen rhinoplasty patients at higher risk for BDD. Level of Evidence: 2
