Reliability and validity of the Thai version of the WHO‐Five Well‐Being Index in primary care patients

Abstract

Aims: Because of the high patient load in Thailand, we need a practical measurement to help primary physicians detect depression. This study aimed to examine the reliability and validity of the Thai version of the World Health Organization-Five WellBeing Index (WHO-5-T), which is short and easy to use as a screening tool for major depression in primary care patients. Methods: The English version of the WHO-FiveWell-Being Index was translated into Thai. Backtranslations, cross-cultural adaptation and field testing of the pre-final version with final adjustments were performed accordingly. The WHO-5-T was administered randomly to 300 patients in our primary care clinic. Then the patients were further assessed using the Mini International Neuropsychiatric Interview and the Hamilton Rating Scale for Depression as the gold standard of diagnosis and symptom severity, respectively. Results: Conclusions:The Thai version of the WHO-Five WellBeing Index was found to be a reliable and valid self-assessment to screen for major depression in primary care setting at a cut-off point of <12.

Propiedades psicométricas del Índice de Bienestar General-5 de la Organización Mundial de la Salud en pacientes parcialmente edéntulos

“…Este instrumento cuenta con versiones previas de 28, 22 y 10 ítems con aceptable desempeño; sin embargo, la versión más reciente y de mayor aplicación, dada su brevedad, es la de 5 ítems (WHO-5 WBI), que identifica posibles casos de episodio depresivo mayor en la población general (11-13) y en pacientes adultos con diferentes enfermedades (11,(14)(15)(16). A pesar de su eficiencia, a la fecha solo un estudio describe el estado de bienestar emocional en pacientes que requieran atención odontológica empleando el WHO-5 WBI (17).…”

“…De forma general, estos estudios reflejan adecuadas medidas: consistencia interna (0.91-0.93), confiabilidad prueba-reprueba (coeficiente de correlación intraclase: 0.613), validez de constructo (raíz del cuadrado medio del error de aproximación: 0.09, IC90%: 0.057-0.125, índice comparativo de ajuste: 0.99, índice de Tucker-Lewis: 0,97), discriminante (sin diferencias estadísticamente significativas entre las medias de los puntajes de WHO-5 WBI de acuerdo a características sociodemográficas) y concurrente (la correlación de Spearman entre los dominios de WHO-5 y WHOQOL-BREF fue >0.50, excepto en el dominio social: 0.37), lo que revela que esta escala es útil para el monitoreo del progreso individual de un paciente (14,15,(18)(19)(20)(21)(22)(23).…”

The utility of WHO-five-well-being index as a screening tool for depression among elderly

“…According to this study, those who met the diagnosis of major depression according to MINI had significantly lower WHO-5-T scores when compared to those not depressed. 16 Furthermore, WHO-5 also exhibited a good convergent validity, as evidenced by a good Pearson's correlation coefficient (r) of -0.68 (p<0.0001) with GDS-15. This guarantees the validity of the WHO-5 in screening for depression among elderly.…”

“…The two screening tools showed a moderate convergent validity (r=-0.54, p<0.0001). 16 WHO-5 also displayed a Cronbach's Alpha of 0.85. Thus, the internal consistency was found to be good.…”

“…[12][13][14] However, the amount of published literature intending to ascertain the utility of the WHO-5 as a screening tool for geriatric depression are fewer in number. 15,16 The WHO-5, being shorter than GDS-15, is easier to administer. 17 However, there is a need to ascertain the utility of this screening tool in varied settings.…”
