Abstract
Background: This study aimed to evaluate the practical utility of Respondent-Driven sampling (RDS) among regular tobacco and alcohol users in Taipei, Taiwan. Methods: RDS was implemented from 2007 to 2010 to recruit seed individuals who were 18 to 50 years old, regular tobacco and alcohol users, and currently residing in Taipei. Each respondent was asked to refer up to five friends known to be regular tobacco smokers and alcohol drinkers to participate in the present study. Information pertaining to drug use was collected using an audio Computer-Assisted Self-Interview instrument. RDSAT software was used for data analyses. Results: The prevalence estimates of Illegal-Drug-Using behaviors attained equilibrium after three to five recruitment waves. Nearly One-Fifth of the participants had ever used illegal drugs, of whom over 60% were polydrug users. The RDS-Adjusted prevalences of Illegal-Drug-Using behaviors among Early-Onset smokers were all two or three times higher than those among Late-Onset smokers. Conclusions: Our results provided an empirical basis for the practicality and feasibility of using RDS to estimate illegal drug use prevalence among regular tobacco and alcohol users.
