Validez del cuestionario PHQ-2 para la detección de depresión en personal sanitario colombiano durante Covid-19 / Validity of the PHQ-2 questionnaire for the detection of depression in Colombian health personnel during Covid-19

RESUMEN: Introducción: La sintomatologia depresiva en profesionales de la salud asociado a crisis virales es de alta prevalencia a nivel global, siendo su detección una prioridad por lo cual, el objetivo de esta investigación fue analizar la validez convergente y consistencia interna del cuestionario de salud del paciente-2 (PHQ-2) en profesionales sanitarios. Método: Estudio eSalud donde se recopilaron datos transversales en línea (n=725), de 281 médicos generales, 237 médicos especialistas y 207 enfermeras durante la cuarentena colombiana, entre el 20 de abril y el 10 de agosto de 2020. Edad promedio 41,3 años (± 8,76). El 38,4% eran hombres (278) y el 61.6% mujeres (447). El 66.1% del personal sanitario atendió pacientes contagiados por coronavirus y el 33,9% no prestó estos servicios. Se administró la versión de 9 ítems del PHQ, validada en población colombiana junto a la versión de 2 ítems del PHQ. Resultados: Se encontró una alta correlación entre las escalas (r=.860, P<0.001), demostrando la validez convergente del PHQ-2 para medir la sintomatología depresiva. La consistencia interna del PHQ-2 fue adecuada, con un Alpha de Cronbach de 0.80 (I.C.= 0.76 - 0.83). Conclusiones: El PHQ-2 presenta adecuados estándares psicométricos de confiabilidad y validez, por lo que su rápida administración, fácil calificación e interpretación, lo convierte en un instrumento confiable y valido para la detección rápida, sin sobrecargas laborales, de los síntomas depresivos en médicos y enfermeras que atiendan o no pacientes en condiciones de brotes virales.

ABSTRACT Background: Depressive symptomatology in health professionals associated with viral crises is highly prevalent globally, being its detection a priority. Therefore, the objective of this research was to analyze the convergent validity and internal consistency of the Patient Health Questionnaire (PHQ-2) in healthcare professionals. Method: E-Health study where cross-sectional data was collected online (n = 725), from 281 general practitioners, 237 specialist doctors and 207 nurses during the Colombian quarantine, between April 20 and August 10, 2020. Average age 41.3 years (± 8.76). 38.4% were men (278) and 61.6% women (447). 66.1% of health personnel treated patients infected with coronavirus and 33.9% did not provide these services. The 9-item version of the PHQ was administered, validated in the Colombian population together with the 2-item version of the PHQ. Results: A high correlation was found between the scales (r = .860, P <0.001), demonstrating the convergent validity of the PHQ-2 to measure depressive symptomatology. The internal consistency of the PHQ-2 was adequate, with a Cronbach's Alpha of 0.80 (I.C. = 0.76 - 0.83). Conclusions: The PHQ-2 has adequate psychometric standards of reliability and validity, so its rapid administration, easy qualification and interpretation, makes it a reliable and valid instrument for the rapid detection, without work overload, of depressive symptoms in doctors and nurses whether or not they care for patients with viral outbreaks.

Use of Patient Health Questionnaires (PHQ-9, PHQ-2 & PHQ-1) For Depression Screening in Singapore Primary Care

@#Introduction: Depression is common and debilitating, yet treatable; however, it is often overlooked in primary care settings. The second leading cause of disease burden globally, it has significant socioeconomic consequences in Singapore. Hence there is a need for well-validated screening tools to identify depressed patients in primary care. We had previously validated the 9-item Patient Health Questionnaire (PHQ-9) against a structured interview diagnosis of major depressive disorder (Mini International Neuropsychiatric Interview) in 400 patients in a local primary care clinic . The present study was a secondary analysis undertaken to evaluate the performance of 1-and 2-item versions of the PHQ (PHQ-1 and PHQ-2) as compared to the full instrument. Results: For screening of major depression in local primary care clinic, PHQ-9 shows good validity and reliability. It had sensitivity of 91.7%, specificity of 72.2% (optimal cutoff score 6), with good internal consistency (Cronbach's alpha 0.87). Sensitivity and specificity for PHQ-2 (optimal cutoff score 2) were 91.7% and 66.8% respectively; whereas that for PHQ-1 (optimal cutoff score 1) was 83.3% and 62.9% respectively. For settings where an ultra-brief screen is preferred, PHQ-2 and PHQ-1 may be employed with limitations. Overall prevalence of major depressive disorder in this study was 3.0%.

The Standardization of the Korean Version of the Patient Health Questionnaire-2 / 신경정신의학

OBJECTIVES: An early diagnosis to improve the outcome of depression demands a briefer and more reliable measure than any other diagnosis. The Patient Health Questionnaire (PHQ) is reliable measure made in 1999. In this study, we tried to verify the reliabilty and validity of two types of PHQ-2, and to compare these two types. METHODS: From July of 2011 to September of 2012, a total of 74 outpatients and inpatients in the Department of Psychiatry, Keimyung University Dongsan Medical Center performed the depression scales. As a normal control group, 58 individuals working in the hospital performed the PHQ-2 and PHQ-9. RESULTS: The internal consistency and test-retest reliabilty were favorable. Two types of the PHQ-2 were statistically significant in correlation between item and total scores. In comparison of mean scores of the PHQ-2 between two groups, the differences between groups were statistically significant. Correaltion of the total scores of other depression scales with those of the PHQ-2 was statistically significant both in scales. Examined according to the severity of depression by other scales, the total mean scores of the PHQ-2 tended to increase according to the severity of depression. The optimal cut-off score was 3 in Scaled PHQ-2 (Sensitivity : 91.9%, Specificity : 100%). CONCLUSION: The assessed reliabilty and validity of the PHQ-2 made it an attractive measure for depression screening over other scales. Scaled PHQ-2 was more reliable and valid than Yes or No PHQ-2. Therefore, the PHQ-2 is a briefer and more useful measure for screening depression.
