Abstract

Adolescent smoking in Indonesia, including Makassar City (ages 12–15), contributes to the projected rise of adult smokers. Theatre for Social Change (TFSC) is an art-based health promotion method addressing smoking behaviour using the Theory of Planned Behavior (TPB). This quantitative, quasi-experimental study applied a pretest–post test design without control, involving 200 respondents before intervention and 186 after, with short-term retention measured later. Data were collected via questionnaires, focus group discussions, and observations, and analysed using chi-square, paired t-test, and logistic regression. Results showed a significant increase in knowledge immediately after intervention (p < 0.005), but no difference between short-term post-tests (p = 0.966). Significant effects (p < 0.005) were found in TPB variables: Attitude, Perceived Behavioural Control, Subjective Norm, Behavioural Belief, Normative Belief, Control Belief, and Intention. TFSC effectively delivers anti-smoking messages, sustaining knowledge for up to seven days.
