Abstract
El Apoyo Social es uno de los factores determinantes del nivel
de salud mejor documentados. Las diferencias culturales y en el uso de la
lengua entre España y otros países de habla española aconsejan prudencia
en el empleo de los mismos instrumentos de medida. Además, los instru-
mentos validados en España se han basado en muestras muy específicas y
pequeñas. El objetivo de este estudio ha sido el desarrollo de un cuestiona-
rio de Apoyo Social para propósitos generales que supere esas limitaciones.
Método: se llevaron a cabo análisis factoriales exploratorio y confirmatorio,
así como un estudio de la consistencia interna, la fiabilidad, validez conver-
gente, validez de contenido y legibilidad en una muestra de 1080 partici-
pantes (48.2% mujeres, edad media 33.51). Resultados: hallamos, replicamos
y confirmamos (con muy buen ajuste) una estructura de tres factores
(Apoyo de Amigos, Familia y Personas Relevantes) que explican una va-
rianza cercana al 73%, con una excelente consistencia interna (.94 o más) y
fiabilidad, y con indicios significativos de validez convergente con otras
medidas de Apoyo Social y de salud relacionadas. Conclusiones: los paráme-
tros de validez estructural, consistencia interna, fiabilidad y validez conver-
gente tomados en su conjunto, presentan un perfil optimizado en compa-
ración con el resto de los cuestionarios revisados
Social Support is one of the most well documented factors in- fluencing health outcomes. Cultural differences and language use between Spain and other Spanish-speaking countries advise caution in the use of the same measurement instruments. Furthermore the instruments validat- ed in Spain have been developed with very specific or small samples. The aim of this instrumental study was to develop a new general purpose Social Support Questionnaire that overcomes these limitations. Method: With a sample of 1080 participants (48.2% women, mean age 33.51), an explora- tory and confirmatory factor analysis was conducted, examining its internal consistency, reliability, convergent validity, content validity and readability. Results: A three-factor structure (Friends, Family and Significant Others Support) was replicated and confirmed (with a very good fit), explaining nearly 73% of the variance with an excellent internal consistency (.94 or more) with significant evidence of convergent validity with other related measurements of Social Support and Health. Conclusions: The parameters of structural validity, internal consistency, reliability and convergent validi- ty, taken together, present an optimized profile when compared to the rest of the reviewed surveys.
