Information-Motivation-Behavioral Skills Model According to the Role of Impulsivity Modulator in Women with Body Mass Index Above 25

Abstract

Aim and Background: The present study was conducted to investigate the informational-motivational-behavioral structural model based on the role of impulsivity moderator among women with body mass index above 25. Methods and Materials: The present study was a cross-sectional correlation of structural equations. The statistical population of the study was all women referring to diet centers, health centers and sports clubs in Isfahan in 2020-2021, from which 444 people were selected by multi-stage sampling method. A researcher-made information-motivational-behavioral questionnaire and Patton et al.'s (1959) impulsivity questionnaire were used to collect data. Amos software (24V-) was used for data analysis. Findings: The results showed the moderating role of impulsivity in the mentioned model (X2/df = 3.46, GFI = 0.981, CFI = 0.977, RMSEA = 0.08, SRMR = 0.073, NFI = 0.970, TLI = 0.928 and AGFI= 0.924). In the three groups of low, medium and high impulsivity, health behavior was influenced by information. In the moderate impulsivity group, health behavior was influenced by motivation. In the three groups of low, medium and high impulsivity, health behavior was affected by behavioral skills. In individuals with low and high impulsivity, information had a significant indirect effect on health behavior through behavioral skills. In individuals with high impulsivity, motivation had a significant indirect effect on health behavior through behavioral skills. Conclusions: The application of these structures such as information, motivation, behavioral skills and attention to levels of impulsivity can help researchers and therapists in the field to prevent obesity and even design appropriate treatments and good diets.
