Construction and Validation of Smoking Abstinence Self – Efficacy Scale

Smoking is the most common addictive drug and is the main gate for other substance abuse. Relapse is one of the main problems in smoking cessation programs. Smoking abstinence self-efficacy plays a basic role in preventing of re-addiction or relapse after quitting smoking. The aim of this study was to construct and validate smoking abstinence self-efficacy scale for Iranian population. At the first, a questionnaire with 52 questions was constructed based on four international scales. Two hundred students who had a history of smoking were randomly chosen at the University of Birjand and completed the questionnaire. Since Bartlett's test of sphericity was significance (KOM= .88), a factorial exploratory analysis was applied on the scale. Using a factor analysis with Varimax rotation and method of items analysis, 23 questions were chosen. With factorial confirmatory analysis, a scale with 13 questions and in two factors derived. The concurrent validity of the scale was calculated with General Self-Efficay (GSE10). The results showed there was a significant positive correlation among them. These findings show the abstinence self-efficacy scale with 13 questions is a valid tool and can be used in smoking cessation and other drug abuse prevention programmes in Iran.
