ROMANI, Yelitze; DIAZ, Beatriz; CARDENAS, María  y  ZORAIDE, Lugli. Design and validation of a weigh control self-efficac inventory. Clínica y Salud [online]. 2007, vol.18, n.1, pp.45-56. ISSN 1130-5274.

This paper presents the development and validation of a weight control selfefficacy inventory measuring self-efficacy perceptions in three areas of weight control -feeding style, influence of external stimuli on over-eating behaviors and physical activity patterns. Following an exhaustive literature review, an opinion interview and consultation with 4 experts in the area, 120 items were built. The statistical item analysis in a sample of 193 students allowed us to sort out 37 items out of the original pool. Then, reliability and validity analyses were performed in a sample of 439 students. Factor analysis resulted in 3 factors explaining 44.083% of the total variance. Satisfactory internal consistencies were found for each factor (.88, .91 and .88 respectively). Results are discussed and directions for future research are suggested.
