Lifestyle Scores and Behavior Change Mindset: A Cross‐Cultural Validation Study of Simple Lifestyle Indicator Questionnaire in Farsi

Background and Aims: Examining lifestyle factors is an essential part of health promotion. The goal of this study was to translate, culturally adapt, and validate the Simple Lifestyle Indicator Questionnaire (SLIQ) for Farsi-speaking populations. Additionally, it explored the relationship between lifestyle scores and behavior change mindset, focusing on readiness for change and personal control. Methods: , intraclass correlation coefficients (ICCs), and Spearman's rank correlations. The relationship between behavior-change dimensions and SLIQ scores was obtained using multivariable linear regression models. Results: < 0.05). Higher SLIQ scores were linked to better adherence to healthy behaviors and increased readiness for change. Adaptation showed cultural appropriateness with slight alterations. Regression analysis highlighted a significant relationship between SLIQ scores and daily routines, dietary choices, and personal control. Conclusion: The Farsi SLIQ is a reliable and valid tool for assessing lifestyle behaviors in clinical and research settings. Because the scale is simple, it is well suited for behavior-change interventions; our findings also show that perceived control and readiness to change are key drivers of healthy lifestyles. However, findings should be interpreted cautiously because self-reported data, particularly on alcohol and tobacco use, may be biased.
