Smoking-Cessation Success Prediction Scale: Development, Validity, and Reliability Study

Abstract

This study has been conducted with the aim of testing the validity and reliability of the Smoking Cessation Success Prediction Scale (SCSPS). The study was carried out between March 2017 to March 2018 with individuals who had applied to the smoking and quitting polyclinic of an education and research hospital after approval from the institution and the ethics committee. The sample of the study is comprised of 148 adult individuals. The test-retest method was conducted with 34 people. The data have been collected using a questionnaire prepared by the researchers and the SCSPS, which has a valid scope. The validity and reliability of the scale have been assessed using the programs IBM SPSS 23 and AMOS 23. In the study, the validity-rate test result for the scope is 0.77, and Bartlett's sphericity test is significant (p < .001). Explanatory factor and confirmatory factor analyses have been performed to determine the structural validity of the SCSPS. The result of the exploratory factor analysis concludes the scale to have 10 items and two factors. The scale is shown to be reliable due to the results of Cronbach's alpha coefficient and the test-retest. SCSPS which developed was determined as a valid and reliable measurement tool.
