To assess whether a brief dietary screener designed to assess fast food and beverage consumption in a primarily Caucasian, adolescent population, is also valid and reliable in an overweight, adolescent, Latina population. This screener was developed by University of Minnesota to assess beverage consumption (9 items) and fast food consumption (13 items) in normal weight, primarily Caucasian, adolescents (ages 11–18). Thirty-five at risk for overweight (BMI ≥85th percentile), adolescent (ages 14–17), Latina females were recruited from East Los Angeles and completed the screener twice, approximately seven to 14 days apart, during the fall of 2007. Dietary intake was also assessed by three-day diet records. Spearman correlation and simple Kappas were employed for test-retest assessment and comparisons between the screener and the records. Test-retest assessment yielded a mean Spearman or Kappa statistic of 0.49 with 17 of the 21 responses being significant (P<0.05). Validity was much lower and yielded a Kappa statistic of only 0.08 and no responses were significant. Although this screener appeared to be a valid and reliable measure to assess beverage and fast food consumption in a primarily Caucasian, adolescent population, it does not appear to be appropriate for an overweight Latina female adolescent population.
