Abstract

Background: The present research aimed to determine the effect of an educational intervention based on the extended theory of planned behavior (ETPB) on waterpipe (WT) smoking cessation in women. Methods: The present quasi-experimental had a pre-test, post-test design with 3, 6 and 12 months follow-ups was conducted in Bandar Abbas city, south of Iran in December 2021-March 2023. A total of 448 women over the age of 15 (224 in the intervention group (IG), 224 in the control group (CG)), using a two-stage cluster sampling method participated. The educational intervention focused on WT smoking cessation implemented in 14 sessions. The educational methods in the training sessions were lectures, collaborative discussions, Q&As, brainstorming, role plays, and peer education. The main outcome was WT cessation behavior. Repeated measures ANOVA tests and post hoc were run to compare the IG and CG at baseline in terms of demographic variables, t-test and chi square test, and in the four points of time of data collection. The data were analyzed in Stata14. A p-value < 0.05 was considered as statistically significant. Results: The mean and standard deviation of WT cessation behavior and all ETPB constructs in the IG was significantly higher than the CG. After the educational intervention, in the IG, the perceived behavioral control, attitude, subjective norm, intention and knowledge increased, and the weekly smoking and WT smoking habit decreased (P < 0.001). The CG did not have any significant change in other variables except for the increased knowledge score. During the 12-month follow-up, the cessation rate was 43.81% (P = 0.645) in the IG and 7.45% in the CG (P = 0.081). Conclusions: The educational intervention positively affected WT smoking reduction and cessation in women through influencing the ETPB constructs. It is strongly recommended to design theory-based interventions beyond the individual level with an emphasis on interpersonal relationships to facilitate WT cessation as far as possible. © The Author(s) 2024.
