Methods
Fordyce happiness
This quasi-experimental study was conducted on female water pipe smokers in Iran, from September to January 2021. The participants (n = 68) were selected using convenience sampling and assigned to the intervention and control groups (34 subjects per group) by blocked randomization. The intervention group received a happiness-based education for one month (eight sessions) based on the Fordyce happiness program. The control group did not receive any special education. Data were collected using the Water Pipe Dependence Scale and the Oxford Happiness Questionnaire before and two months after the intervention. Data were analyzed using descriptive statistics, Chi-square, Fisher’s exact test, Independent t-test, Mann-Whitney, and Wilcoxon tests by SPSS software version 22.
