Abstract

Respondent-driven sampling (RDS) is often viewed as a superior method for recruiting hard-to-reach populations disproportionately burdened with poor health outcomes. As an analytic approach, it has been praised for its ability to generate unbiased population estimates via post-stratified weights which account for non-random recruitment. However, population estimates generated with RDSAT (RDS Analysis Tool) are sensitive to variations in degree weights. Several assumptions are implicit in the degree weight and are not routinely assessed. Failure to meet these assumptions could result in inaccurate degree measures and consequently result in biased population estimates. We highlight potential biases associated with violating the assumptions implicit in degree weights for the RDSAT estimator and propose strategies to measure and possibly correct for biases in the analysis.

Resumen

Respondent-driven sampling (RDS) suele ser considerado como uno de los mejores métodos para el reclutamiento de poblaciones de difícil acceso y con riesgos de salud desproporcionados con respecto al resto de la población. Analíticamente, RDS ha sido elogiado gracias al uso de ponderaciones post-estratificadas para compensar la falta de aleatoriedad en el muestreo, logrando obtener así estimadores poblacionales insesgados. A pesar de ello, los estimadores poblacionales que se obtienen con RDSAT (RDS Analysis Tool) han mostrado ser sensibles a variaciones en las ponderaciones por tamaño de la red. Varios supuestos están implícitos cuando usando los ponderaciones por tamaño de red y la validez de estos supuestos raramente son evaluados. Una violación de esos supuestos podría llevar a cálculo de ponderaciones erróneas y por lo tanto, a estimaciones poblacionales sesgadas. Nosotros discutimos los diferentes tipos de sesgos en los estimadores RDSAT que pueden llegar a surgir debido a violaciones en los supuestos necesarios para el cálculo de las ponderaciones por tamaño de red, y proponemos estrategias para medir y corregir ese sesgo.
