Development and preliminary testing of a brief screening measure of healthy lifestyle for diabetes patients.

Improving diabetes control is a critical issue world-wide, because mortality rates and costs are increasing dramatically. Maintaining a healthy lifestyle is positively associated with diabetes control. However, the availability of practical screening tools suitable for determining and modifying healthy or unhealthy lifestyle choices is limited. The main aim of this study was to determine the appropriateness of the type 2 diabetes and health promotion scale (T2DHPS) for use in patients with type 2 diabetes. This study examined the Cronbach's alpha, content validity, construct and concurrent validity of the Chinese language version of the T2DHPS for assessing lifestyle and disease control among patients with type 2 diabetes. The dimensions of the T2DHPS were generated from the Chinese version of adult health promotion and interviews with experts, and were corroborated by the literature. A total of 323 patients previously diagnosed with type 2 diabetes were recruited. A cross-sectional, descriptive design questionnaire was developed and tested at diabetes outpatient departments in three teaching hospitals between August 2010 and June 2011. Construct validity was established using factor analysis. The total and subscale scores of the T2DHPS were correlated with biomarkers of diabetes control for concurrent validity. Kaiser-Meyer-Olkin (KMO) and Bartlett's sphericity tests showed that the sample met the criteria required for factor analysis. A 28-item Likert-type scale of the T2DHPS was established, and explained 56.7% of the total variance. The simplified version of the T2DHPS was made up of six dimensions of behavior: physical activity, risk reduction, stress-management, enjoy life, health responsibility and a healthy diet. The reliability coefficient for the total scale was 0.89, and alpha coefficients for the subscales ranged from 0.63 to 0.86. Concurrent validity indicated that the T2DHPS is significantly positively associated with diabetes control. T2DHPS was shown to be a reliable and valid tool for assessing patients with type 2 diabetes, and can possibly predict diabetic control. This scale appears to be a useful screening tool for type 2 diabetic people in primary health care settings, to promote health status through modification of an unhealthy lifestyle.

Psychometric evaluation of the Persian version of the Type 2 Diabetes and Health Promotion Scale (T2DHPS): a diabetes-specific measure of lifestyle.

A healthy lifestyle is important for maintaining health and preventing complications in patients with type 2 diabetes, and yet, few instruments are available to measure this. The aim of the present study was to examine the psychometrics of a recently developed tool that can be used to screen for a health-promoting lifestyle in patients with type 2 diabetes. Data were collected from outpatients attending diabetes clinics. The Type 2 Diabetes and Health Promotion Scale (T2DHPS), EQ-5D, medical records and a demographic questionnaire were administered to 368 participants. Forward-backward translation of the original English version was used to develop a Persian version. Internal consistency of the scale was assessed by Cronbach's alpha and item-to-total correlation. Acceptability was measured by assessing floor and ceiling effects for each item and subscale. The item scaling test was used to examine the convergent and discriminant validity of the measure. Pearson correlation was used to determine the predictive validity of the scale. An explanatory factor analysis and known-group method were used to establish construct validity. Adjusted item-total correlations were higher than 0.20. Cronbach's alpha for the 28-item scale was 0.88 and for subscales ranged from 0.53 to 0.94. Correlations between the total score and subscale scores were significant (<0.01) and adequate (r's ≥ 0.53). There were significant relationships between the T2DHPS and both the EQ-5D and indicators of glycaemic control. Convergent and discriminant validity of the scale was established. Significant differences in lifestyle dimensions were present between different groups of patients, demonstrating known-group validity. A six-factor solution was obtained that explained 54.6% of the total variance. The T2DHPS is a valid and reliable tool for investigating lifestyle behaviours in patients with type 2 diabetes. Further studies to establish the psychometric properties of the scale in other languages and cultures are suggested.
