Background: The South Oaks Gambling Screen (SOGS) is one of the most widely used screening instruments for evaluating addiction to gambling. Method: The main objective of this study is to analyze whether the SOGS is a reliable instrument and what characteristics of studies on the SOGS are linked to its reported reliability. Results: A meta-analysis was carried out with 63 studies including 65 independent samples. The mean value of a was .86 (95% CI of .84–.88), with high heterogeneity (I2 = 98.27%). The variables that explain the most heterogeneity were the continent where the study was performed (R2 = .61), application to participants with or without clinical problems (R2 = .58), the form of administration of the questionnaire (R2 = .56), and the standard deviation in the SOGS score (R2 = .13). Conclusions: The results show that the SOGS is a reliable instrument for evaluating gambling addiction. However, the meta-analysis highlights the need to report the reliability values for each empirical study and to provide a set of recommendations for researchers and professionals who use this instrument.

Meta-análisis de Generalización de la Fiabilidad del South Oaks Gambling Screen (SOGS). Antecedentes: el South Oaks Gambling Screen (SOGS) es uno de los instrumentos de screening más utilizados para los problemas de adicción al juego. Método: el objetivo de esta investigación es analizar si el SOGS es un instrumento fiable y qué características de los estudios tienen efectos en su fiabilidad. Resultados: se llevó a cabo un meta-análisis con 63 estudios incluyendo 65 muestras independientes. El valor medio de a fue .86 (95% CI .84–.88), con una elevada heterogeneidad (I2 = 98.27%). Las variables que explicaron más heterogeneidad fueron el continente en que se desarrolló el estudio (R2 = .61), la aplicación en participantes con o sin problemas clínicos (R2 = .58), la forma de administración del cuestionario (R2 = .56) y la desviación estándar en la puntuación del SOGS (R2 = .13). Conclusiones: los resultados muestran que el SOGS es un instrumento fiable para evaluar los problemas de adicción al juego. Por otro lado, el meta-análisis recalca la necesidad de reportar los valores de fiabilidad en cada investigación empírica que se realice, y proporciona una serie de recomendaciones para investigadores y profesionales que utilicen este instrumento.
