Concurrent and Convergent Validity of the Simple Lifestyle Indicator Questionnaire

Abstract

Lifestyle issues including physical activity, diet, smoking, alcohol consumption, and self-reported stress have all been shown to predispose people to higher risk of cardiovascular disease. This study provides further psychometrics on the Simple Lifestyle Indicator Questionnaire (SLIQ), a short, easy-to-use instrument which measures all these lifestyle characteristics as a single construct. One hundred and ninety-three individuals from St. John's, Newfoundland, and Labrador, Canada completed the SLIQ and reference standards for diet, exercise, stress, and alcohol consumption. The reference standards were a detailed Diet History Questionnaire (DHQ), the Social Readjustment Rating Scale (SRRS), the SF36 Health Status Questionnaire, and a survey of eight questions from a cardiovascular risk questionnaire. Physical activity score was compared with number of steps on a pedometer. Correlations between scores on the SLIQ and the reference standards were the SLIQ versus DHQ (r = 0.679, P = 0.001), SLIQ versus pedometer (r = 0.455, P = 0.002), SLIQ versus alcohol consumption (r = 0.665, P = 0.001), SLIQ versus SRRS (r = −0.264, P = 0.001), SLIQ versus eight-question risk score (r = 0.475, P = 0.001), and SLIQ versus Question 1 on SF36 (r = 0.303, P = 0.001). The SLIQ is sufficiently valid when compared to reference standards to be useful as a brief assessment of an individual's cardiovascular lifestyle in research and clinical settings.

Women's and Men's Differing Experiences of Health, Lifestyle, and Aging with Multiple Sclerosis

“…21 Current level of fatigue was measured using a 100-mm VAS, and stress was measured using the subscale of the Simple Lifestyles Indicator Questionnaire, an ordinal scale ranging from 1 (low stress) to 6 (high stress). 22…”

“…Lifestyle-related factors included physical activity, diet, alcohol use, and smoking captured in the Simple Lifestyles Indicator Questionnaire. 22 Physical activity and diet scores ranged from 0 to 24 and 0 to 15, respectively, with higher scores suggesting a healthier lifestyle. Alcohol use was counted as the number of drinks per week, and smoking was categorized as nonsmoker or current smoker.…”

Development and psychometric evaluation of the community care competency scale in multi‐ethnic undergraduate nursing students

“…The scores of CCCS and JSAPC were normally distributed, thus, Pearson product–moment correlation was performed. Pearson product–moment correlation coefficient between CCCS and JSAPNC showed significantly positive correlation ( r = 0.20, p < 0.05), as shown in Table , thus indicating acceptable convergent validity (Godwin et al, ).…”

“…Skewness and kurtosis values were within the range of ±2 and indicated normally distributed variables (George & Mallery, ). We expected a correlation coefficient in the range of 0.2–0.4 for convergent validity (Godwin, Pike, Bethune, Kirby, & Pike, ).…”

Assessment of Lifestyle in rural youth using Simple Lifestyle Indicator Questionnaire (SLIQ)

“…Lifestyle issues like dietary habit, physical activity, smoking, alcohol consumption and self reporting stress have shown to predispose people to higher risk of developing cardiovascular illnesses and other NCD's. 7 Significant lifestyle changes due to rapid urbanization, dominance of personal transport, the introduction of labour saving devices, the easy availability of high fat and dense caloric food, increased communication devices as well as decreased occupational work demand. 8 The rapid change of today's society has brought a change in our lifestyle.…”
