Abstract:
The purposes of this correlational predictive research were to examine correlation between perceived dual contraceptive method use self efficacy, attitudes toward dual contraceptive method use, perceived risk of sexually transmitted disease, AIDS and unwanted pregnancy, normative friend belief of dual contraceptive method use and dual contraceptive method use. Three hundred and fourty-five vocational female students aged 18-24 years in the upper south of Thailand, were recruited using multistage random sampling. Data were collected using the perceived dual contraceptive method use self efficacy questionnaire, attitudes toward dual contraceptive method use questionnaire, perceived risk of sexually transmitted disease, AIDS and unwanted pregnancy questionnaire, normative friend belief of dual contraceptive method use questionnaire, and dual contraceptive method use questionnaire. The questionnaires were tested for their content validity by a panel of expert, their CVI were 0.8, 0.8, 0.8, 1.0 and 1.0, respectively. Their Cronbach s alpha coefficients were 0.79, 0.70, 0.87, 0.51, and 0.50 respectively. Data were analyzed using bivariate correlations and multiple regression. The results revealed that: 1. Perceived dual contraceptive method use self efficacy was positively and significantly related to dual contraceptive method use among vocational female students in the upper part of the South (r=.279 , p< .05). Normative friends belief of dual contraceptive method use (r= .006), perceived risk of sexually transmitted disease, AIDS and unwanted pregnancy (r= -.048) and attitudes toward dual contraceptive method use (r= .026) were not related to dual contraceptive method use (p > .05). 2. Perceived dual contraceptive method use self efficacy, normative friend belief of dual contraceptive method use, perceived risk of sexually transmitted disease, AIDS and unwanted pregnancy and attitudes toward dual contraceptive method use explained 7.9%. of the variance of dual contraceptive method use of vocational female students in the upper south. Perceived dual contraceptive method use self efficacy (β= .282, p < .05) was the only significant predictor of dual contraceptive method use.
