title: Relationship of social cognitive theory concepts to mothers' dietary intake and BMI.
abstract: Women tend to have the greatest responsibility for and influence on the home food environment. Understanding theoretical concepts as they pertain to mothers' food-related behaviours could inform the development of interventions that enhance mothers' ability to create healthy family food environments that support optimal child development and help attenuate obesity rates. Likert scales assessed Social Cognitive Theory concepts [i.e. self-efficacy, self-regulation (sets goals, self-reward, self-monitoring, environmental structuring), outcome expectations] and coping of 201 mothers in the context food-related activities. ANOVA determined whether diet and BMI differed among mothers scoring in the highest, middle, and lowest tertiles on the Likert scales. For self-efficacy, coping, sets goals, and outcome expectations scales, lowest tertile mothers had significantly higher BMIs than highest tertile mothers. The lowest tertile for self-efficacy, self-reward, and self-monitoring consumed significantly less fibre, vitamin C, magnesium, potassium, and fruit and vegetables than upper tertiles. On the self-efficacy scale, the lowest tertile consumed significantly more calories, fat, and cholesterol than higher tertiles. Environmental structuring scale findings indicate users of television during dinner had significantly lower intakes of fibre, vitamin C, magnesium, potassium, and fruits and vegetables than those almost never using TV during dinner. Stepwise regression revealed self-monitoring, environmental structuring, self-reward, and outcome expectations were significant positive predictors of self-efficacy. Self-monitoring was a significant positive predictor of outcome expectations. Associations between theoretical concepts, mothers' dietary intakes, and BMIs point to the need to incorporate components that build self-efficacy, self-regulation, outcome expectations, and coping skills into health promotion interventions.
