The objective of this study is to determine factors affecting the efficiency of the drug prevention
program of youth volunteer (PKBPD) in Kuala Terengganu, Malaysia. This quantitative case study
was designed to illustrate the effectiveness of the youth program at various places. Quantitative data
was collected through surveys and interviews. Respondents were among the members who
participated in PKBPD and 245 of them, aged 19-36 years were interviewed. Respondents consist of
150 male participants (61.2 percent) and 95 females (38.8 percent). Data were analyzed using two
types of software : 1) Statistical Package for Social Sciences (SPSS) version 18 through multiple
logistic regression analysis and 2) AMOS version 18 through SEM analysis. The findings are
reported in three parts, namely profiles of PKBPD’s participants, analysis of factors determining the
effectiveness of PKBPD and analysis of causes and effects of the problems faced by PKBPD. The
results showed that there are four significant factors that have contributed to the problems in the
management of PKBPD that 1) no meeting among members, 2) no disclosure to members, 3) lack of
anti-drug abuse programs and 4) members did not know about organized program. Based on this
analysis, the factor that members are not aware of the program or activity is the most influential
factor with the Exp (B) value of 13.261, followed by the absence of meeting with the Exp (B)
7.371, lack of programs and no exposure factors with each value Exp (B) 6.467 and 4.500,
respectively. The study also revealed that PKBPD has experienced problems in management and
need immediate improvements to ensure the drug prevention programs involving youth volunteers
can be implemented effectively.
