Assessing Criterion Validity and Developing Population Norms for the Simple Lifestyle Indicator Questionnaire (SLIQ) in the Elderly

Lay Summary 

Cardiovascular disease is the leading cause of death in Canada. A major risk factor for cardiovascular disease is lifestyle (smoking status, diet, exercise, alcohol use, stress). Currently, however, an instrument to measure cardiovascular lifestyle as a single construct does not exist. The SLIQ was developed to address the need for such an instrument. However, the SLIQ has not been sufficiently tested, nor have population norms been determined. As such, it is not possible to use the instrument as an outcome or exposure measure in large grant applications.
In this study, we hope to measure criterion validity of the SLIQ and to collect normative data in the elderly. To assess criterion validity we will compare scores on the SLIQ with scores on other validated measures of diet, stress, alcohol consumption and exercise. We will recruit people in three age categories: 50-64 years, 65-79 years, and 80+ years, from family physician practices. To assess the population norms we will recruit people from various venues: shopping malls, gyms, and the people recruited from family doctors offices. Once we have more clearly delineated these psychometrics (validity and population norms), we will be in a much better position when applying to CIHR and other granting agencies. As well, research and clinical communities will have a validated instrument for measuring lifestyle and changes in lifestyle behaviour. Data collection for this study is ongoing. For the validation portion of the study, we have collected data on approximately 50 of the planned 300 participants. In addition, we have collected over half of our normative data.
