This study investigated the reliability and factorial validity of General Anxiety Disorder-7 (GAD-7) in the context of university students in Bangladesh. The research aimed to assess whether the original one-dimensional model or a model containing both somatic and cognitive-emotional factors is appropriate. A repeated cross-sectional survey design based on convenience sampling was used to collect data from 677 university students. The factor structure of the GAD-7 was assessed by exploratory factor analysis (EFA) and confirmatory factor analysis (CFA), and its convergent validity was determined by investigating its correlations with Patient Health Questionnaire-9 (PHQ-9) and Patient Health Questionnaire Anxiety-Depression Scale (PHQ-ADS). Results showed excellent reliability of GAD-7 as measured by Cronbach’s α. CFA suggested that a modified one-factor model is appropriate for the sample. This model provided high values of comparative fit index (CFI), goodness of fit index (GFI), and Tucker Lewis Index (TLI), low value of standardized root mean square residual (SRMR) and a non-significant root mean square error of approximation (RMSEA). Correlation between GAD-7 and PHQ-9 was 0.751 and 0.934 between GAD-7 and PHQ-ADS. Overall, the study provided support for modified unidimensional structure for GAD-7 and showed high internal consistency along with good convergent validity.

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

Abstract Background The Patient Health Questionnaire-9 (PHQ-9) is a brief tool to assess the presence and severity of depressive symptoms. This study aimed to validate and calibrate the PHQ-9 to determine appropriate cut-off points for different degrees of severity of depression in Argentina. Methods We conducted a cross-sectional study on an intentional sample of adult ambulatory care patients with different degrees of severity of depression. All patients who completed the PHQ-9 were further interviewed by a trained clinician with the Mini International Neuropsychiatric Interview (MINI) and the Beck Depression Inventory-II (BDI-II). Reliability and validity tests, including receiver operating curve analysis, were performed. Results One hundred sixty-nine patients were recruited with a mean age of 47.4 years (SD = 14.8), of whom 102 were females (60.4%). The local PHQ-9 had high internal consistency (Cronbach’s alpha = 0.87) and satisfactory convergent validity with the BDI-II scale [Pearson’s correlation = 0.88 (p < 0.01)]. For the diagnosis of Major Depressive Episode (MDE) according to the MINI, a PHQ-9 ≥ 8 was the optimal cut-off point found (sensitivity 88.2%, specificity 86.6%, PPV 90.91%). The local version of PHQ-9 showed good ability to discriminate among depression severity categories according to the BDI-II scale. The best cut off points were 6–8 for mild cases, 9–14 for moderate and 15 or more for severe depressive symptoms respectively. Conclusions The Argentine version of the PHQ-9 questionnaire has shown acceptable validity and reliability for both screening and severity assessment of depressive symptoms.

Abstract Background Depression in patients with infertility often goes undiagnosed and untreated. The Patient Health Questionnaire-9 (PHQ-9) and its ultra-brief version (i.e. PHQ-2) are widely used measures of depressive symptoms. These scales have not been validated in patients with infertility. The aim of the present study was to examine the reliability and validity of the PHQ-9 and PHQ-2 in patients with infertility. Methods In this cross-sectional study, a total of 539 patients with infertility from a referral infertility clinic in Tehran, Iran completed the PHQ-9, along with other relevant scales: the WHO-five Well-being Index (WHO-5), the Hospital Anxiety and Depression Scale (HADS), and the Generalized Anxiety Disorder-7 (GAD-7). Factor structure and internal consistency of PHQ-9 were examined via confirmatory factor analysis (CFA) and Cronbach’s alpha, respectively. Convergent validity was evaluated by relationship with WHO-5, HADS and GAD-7. Results The mean total PHQ-9 and PHQ-2 scores were 8.47 ± 6.17 and 2.42 ± 1.86, respectively, and using a cut-off value of 10 (for PHQ-9) and 3 (for PHQ-2), the prevalence of depressive symptoms was 38.6 and 43.6%, respectively. The Cronbach’s alphas for PHQ-9 and PHQ-2 were, respectively, 0.851 and 0.767, indicating good internal consistency. The CFA results confirmed the one-factor model of the PHQ-9 (χ2/df = 4.29; CFI = 0.98; RMSEA = 0.078 and SRMR = 0.044). Both PHQ-9 and PHQ-2 showed moderate to strong correlation with the measures of WHO-5, HADS-depression, HADS-anxiety, and the GAD-7, confirming convergent validity. In univariate analysis, female sex, long infertility duration, and unsuccessful treatment were significantly associated with depression symptoms. Conclusion Both PHQ-9 and PHQ-2 are brief and easy to use measures of depressive symptoms with good psychometric properties that appear suitable for routine use in patients with infertility.

The process of assessing executive functions through behavioral observation scales is still under theoretical and empirical construction. This article reports on the analysis of the factorial structure of the EOCL-1 scale that assesses executive functions, as proposed by the theory developed by Luria, which has not been previously considered in this type of evaluation. In this scale, the executive functions taken into account are error correction, internal behavioral and cognition regulatory language, limbic system conscious regulation, decision making, future consideration of consequences of actions, goal-directed behavior, inhibitory control of automatic responses, creation of new behavioral repertoires, and cognitive–behavioral activity verification. A variety of validity and reliability analyses were carried out, with the following results: (a) an adequate internal consistency level of executive functions between α = 0.70 and α = 0.83, (b) significant convergent validity with a scale that assesses frontal deficits between r = −0.07 and r = 0.28, and (c) the scale’s construct validity that proposes a model with an executive central factor comparative fit index (CFI) = 0.93, root mean square error of approximation (RMSEA) = 0.04 (LO.04 and HI.04), standardized root mean square residual (SRMR) = 0.04, and x2(312) = 789.29, p = 0.001. The findings are discussed based on previous literature reports and in terms of the benefits of using a scale to assess the proposed executive functions.

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.

Resumo O estudo visou comparar escores de ansiedade e depressão em profissionais da saúde em atendimento remoto ou presencial em um hospital universitário brasileiro durante a pandemia de Covid-19 e identificar fatores associados à ansiedade e à depressão. Para tanto, realizou-se um estudo observacional e transversal. Os participantes responderam aos protocolos Patient Health Questionnaire-9 e General Anxiety Disorder-7, além de um questionário sociodemográfico, e foram divididos em três grupos: profissionais da telessaúde (G1), profissionais que exercem de maneira presencial (G2) e profissionais que exercem de ambas as formas (G3). Participaram 159 profissionais da saúde, sendo 36 homens e 123 mulheres, a maioria de enfermeiros, com a média de idade de 42 anos. Os participantes do G2 apresentaram maiores escores de ansiedade e depressão quando comparados aos demais. No entanto, não houve diferenças e associações estatísticas significantes entre esses grupos (p>0,05). ‘Idade’, ‘tipo de profissão’ e ‘receber diagnóstico de Covid-19’ tiveram associações estatísticas com ansiedade e depressão. Concluiu-se que não houve diferença significante entre ansiedade e depressão em profissionais da saúde que trabalham de forma remota ou presencial, assim como não houve associações entre os protocolos e os grupos. ‘Idade’ ‘profissão’ e ‘receber diagnóstico de Covid-19’ podem interferir nesses escores.

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.
