Abstract

The Simple Lifestyle Indicator Questionnaire (SLIQ) was developed to measure five aspects of lifestyle that are shown to impact cardiovascular health. The present study addresses a gap in the literature on the SLIQ by evaluating its sensitivity to change. We recruited forty-one adult participants from a Weight Watchers’ location and a university gym. At enrollment, participants were weighed and asked to complete the SLIQ. Three months later, they were weighed a second time and completed the SLIQ again. Additionally, participants provided self-reports regarding how they felt various health-related aspects of their lifestyle had changed during the study period. Self-reports and weight change were compared with the change in SLIQ scores over the study period. We found that changes in the overall SLIQ scores had a statistically significant correlation with weight change and with participants’ self-reported change in lifestyle. SLIQ sub-scores, specifically those relating to diet and exercise, were found to correlate significantly with self-reports.
