RESEARCH FINDINGS AND DISCUSSIONS
The questionnaires used consist of three variable questions as research independent variables (X). Those three variables were peers influence, attitude to cigarette advertising, and attitude to smoking behavior. The questionnaire also consists of questions about the respondent’s smoking intention
(Y). First, the questionnaires were tested for its validity and its reliability on 50 students of SMU 4 Yogyakarta (one of the candidates to the main respondent) in February 2010. From analyzing the validity and reliability of the questionnaires using Factor Analysis tested, two items of the questions
in one of independent variable in the questionnaire are found to be invalid. After retesting
the questionnaire without using those two items, the research finds that all the items in the questionnaire valid and reliable as a tool of measure. There are three variables in this research, but there are only two variables that were tested which are attitude towards cigarette advertising and attitude towards smoking behavior. While the variable of peers influence are not considered as
the perception’s question or considered as an even question. In this research, the researcher uses
multiple regression analysis to test the hypotheses. Multiple regressions is used to test the effect of peers influence, attitude towards cigarette advertising, and attitude towards smoking behavior toward smoking intention (H1, H2, and H3). First, F test will be conducted to test whether independent
variables altogether can influence the dependent variable. Statistically, the result shows that the measured F is 10.198 with F significant 0.000. In this research, the writer uses _ = 5%. Hence if the F significant value is less than 0.05, consequently the alternative hypothesis cannot be rejected or independent variables statistically altogether can influence the dependent variable. Statistically,
the result shows that significance value (p-value) is 0.000 which is less than 0.1. This means that independent variables consisting of peers influence, attitude towards cigarette advertising, and attitude towards smoking behavior all together simultaneously influence dependent variable.
