Abstract :

Obesity is a health, medical and psychological issue that has many economic, social and personal consequences. This research was conducted with the aim of constructing and investigating the validity, reliability and confirmatory factor analysis of the Scale of Information, Motivation and Behavioral skills in women with a body mass index above 25 in the city of Isfahan.This correlational research is of the validation type and the statistical population of the research included women with a body mass index higher than 25 who had visited diet therapy centers, health centers and sports clubs in Isfahan city in 2014-2016.And for the sample size of the present study, 444 women with a body mass index higher than 25 were selected, and the cluster sampling method was used.A researcher-made scale of information, motivation, and behavioral skills was used to collect data.In order to check content validity, experts were consulted, and to measure construct validity and reliability of the scale, confirmatory factor analysis method was used using Amos and SPSS software.In terms of the relative index of content validity, the scale was 0.62 and the content validity index was above 0.70, and the construct validity aspect was also approved by the experts, the fit indices related to the four confirmatory factor analysis models for the four subscales were at a favorable level.The composite reliability of the information, motivation, behavioral skill and health behavior subscales was (CRI=0.89, 0.87, 0.91 and 0.87 ) respectively. Therefore, this scale can be used in research, clinical and therapeutic situations.
