A lifestyle assessment and intervention tool for pediatric weight management: the HABITS questionnaire

Lifestyle assessment and intervention tools are useful in promoting pediatric weight management. The present study aimed to establish convergent validity and reliability for a quick simple measure of food intake and physical activity/sedentary behaviour. The HABITS questionnaire can be used to identify and monitor behavioural intervention targets.

Thirty-five youths (ages 7-16 years) were recruited from the waiting area of the Jacobi Medical Center Child and Teen Health Services. To establish convergent validity for the HABITS questionnaire, study participants completed the HABITS questionnaire, a 24-h recall and a modified version of the Modifiable Activity Questionnaire for Adolescents (MAQ). Participants completed a second HABITS questionnaire within 1 month to assess test-retest reliability. Internal consistency for dietary and physical activity/sedentary behaviour subscales was assessed using Cronbach's alpha, and test-retest reliability was assessed using Cohen's Kappa coefficient. Spearman's rank correlation coefficients were calculated for individual items using the 24-h recall and the MAQ as reference standards.

The HABITS questionnaire subscales showed moderate internal consistency (Cronbach's alpha of 0.61 and 0.59 for the dietary and physical activity/sedentary behaviour subscale, respectively). The test-retest reliability was 0.94 for the dietary subscale and 0.87 for the physical activity/sedentary behaviour subscale. Several items on the HABITS questionnaire were moderately correlated with information reported in the MAQ and the 24-h recall (r = 0.38-0.59, P < 0.05).

The HABITS questionnaire can reliably be used in a paediatric setting to quickly assess key dietary and physical activity/sedentary behaviours and to promote behaviour change for weight management.
