According to Social Cognitive Theory (Bandura, 1997), nutritional risk would be predicted by perceptions of nutrition efficacy, which in turn would be predicted from four sources : modeling, verbal support, physiological conditions, and nutrition habits.
In telephone interviews with 154 rural elderly adults (44 men, 110 women ; mean age=74.4 years), nutritional risk was measured with Nutritional Risk Index (NRI), Nutritional Screening Initiative (NSI), and seven-high-risk-nutrients consumed less than 50 percent of RDA (Diet Plus Analysis).
Nutrition-efficacy was measured with a new twenty-five-item scale of Perceived Nutrition Barriers (PNB).
Sources of nutrition-efficacy included :
Mealtime modeling-shared meals, household size ; verbal support-people talk to each day, hours talked, number of confidants ; physiological conditions that may affect nutrition-age, body mass, medications, disability, negative affect, and nutrition habits-daily food variety, use of meal services.
Path analysis was performed with each measure of nutritional risk (NRI, NSI, 7-high-risk-nutrients) as a criterion variable, nutrition-efficacy (PNB) as a possible mediating variable, and sources of nutrition-efficacy as predictor variables.
Social Cognitive variables accounted for 58 percent of variance in NRI, 49 percent of variance in NSI, and 29 percent of variance in seven-high-risk-nutrients. (...)
