Abstract

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: A total of 91 healthy individuals were recruited and asked to complete the Farsi SLIQ, the International Physical Activity Questionnaire (IPAQ), and the Healthy Lifestyle and Personal Control Questionnaire (HLPCQ). A translation-back translation process was used to adapt the SLIQ, ensuring accuracy in cultural and linguistic contexts. Psychometric properties, including reliability and validity, were evaluated using Cronbach's α, 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: The Farsi SLIQ showed moderate reliability as shown by Cronbach's α of 0.549 and significant correlations with IPAQ (r = 0.250, p < 0.01) and HLPCQ (β = 0.372, p < 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. © 2026 The Author(s).
