RESUMO
OBJETIVO: Realizar una validación concurrente de la versión corta del Woman Abuse Screening Tool (WAST), un instrumento utilizado en la detección de violencia de pareja hacia la mujer, estimando los índices de validez en población general. MÉTODO: La fuente de información fue la tercera Encuesta de violencia de pareja hacia la mujer de la Comunidad de Madrid de 2014, realizada a mujeres de 18 a 70 años. Como referencia se utilizó la definición de violencia de pareja hacia la mujer basada en un cuestionario de 26 preguntas. La versión corta del WAST incluye dos preguntas con tres respuestas posibles. Se calculan y comparan la prevalencia de violencia de pareja hacia la mujer y los índices de validez del cuestionario según dos criterios de puntuación con intervalos de confianza del 95% (IC95%). RESULTADOS: La tasa de respuesta fue del 60%. Se analizaron 2979 encuestas. La prevalencia de violencia de pareja hacia la mujer fue del 7,6% (IC95%: 6,6-8,5%). Se encontró un 21,1% (IC95%: 19,6-22,5) de test positivos según el criterio 1 y un 11,0% (IC95%: 9,9-12,1) según el criterio 2. El criterio 2 presentó una mayor eficiencia global del test (81,5% [IC95%: 80,1-82,9] para el criterio 1 vs. 88,8% [IC95%:87,7-89,9] para el criterio 2). Los mejores índices se obtuvieron en mujeres a partir de 30 años de edad. CONCLUSIONES: La versión reducida del cuestionario WAST presentó índices de validez aceptables para ser utilizados como cuestionario de cribado de violencia de pareja hacia la mujer. Recomendamos utilizar el criterio 2 de puntuación en la estimación de la prevalencia de violencia de pareja hacia la mujer en encuestas dirigidas a población general
OBJECTIVE: To perform a concurrent validation of the short version of the Woman Abuse Screening Tool (WAST), used to detect intimate partner violence, estimating the validity indexes in the general population. METHOD: The information source was the third Intimate partner violence survey in the Region of Madrid (Spain) conducted on women aged 18-70 in 2014. As the gold standard we used the definition of intimate partner violence based on a 26- question survey. The short version of WAST includes two questions with three possible answers. The prevalence of intimate partner violence and the validity indexes were calculated and compared according to two scoring criteria with 95% confidence intervals (95%CI). RESULTS: The response rate was 60.0%, and 2979 surveys were analysed. The prevalence of intimate partner violence was 7.6% (95%CI: 6.6-8.5). We showed 21.1% (95%CI: 19.6-22.5) positive test results according to WAST criterion 1 and 11.0% (95%CI: 9.9-12.1) according to criterion 2. Criterion 2 presented higher overall efficiency of the test (81.5% [95%CI: 80.1-82.9] criterion 1 vs. 88.8% [95%CI: 87.7-89.9] criterion 2). The best indexes were obtained in women ≥30 years old. CONCLUSIONS: The short version of the WAST showed acceptable validity indexes for use as a screening tool of intimate partner violence in the general population. We recommend using scoring criterion 2 to estimate prevalence of intimate partner violence in surveys on the general population
