Abstract

Most weight control programs facilitate weight loss by encouraging participants to adopt healthy eating patterns and increase physical activity. There is a need for a relatively brief measure of eating habits and physical activity that could be used to evaluate changes in behavior during weight loss treatment The purpose of this series of four studies was to develop and validate such a measure, which was subsequently named the Weight Loss Behavior Scale (WLBS). Study 1 (n = 533) included item and scale development and examination of the WLBS's factor structure and internal consistency. Study 2 (n = 226) evaluated the test-retest reliability and convergent validity of its subscales. Study 3 examined their reliability and internal consistency scales in a predominantly overweight sample (n = 36). Study 4 evaluated the WLBS as a treatment outcome measure in a weight loss intervention (n = 50). Study 1 found that the WLBS contained five internally consistent and stable factors: 1) Concern with Dieting and Weight, 2) Exercise, 3) Overeating, 4) Avoidance of Fattening Foods and Sweets, and 5) Emotional Eating. Study 2 found convergent validity for the WLBS by assessing the correlation of its factors/scales with established inventories of comparable constructs, e.g., dietary restraint, disinhibited eating, and physical activity. Test-retest reliability of the five scales was also supported in this second study. In Study 3, support for the internal consistency and test-retest reliability of the WLBS among overweight individuals was found. Study 4 found that all scales significantly changed in the expected directions after a 5-month behavioral weight loss treatment The findings from this series of studies suggest that the WLBS is a reliable and valid self-report inventory of cognitive and behavioral scales associated with weight control that can be utilized as an outcome measure for weight loss interventions. © 2000, Editrice Kurtis.
