[Validity and Reliability of Two Silhouette Scales to Asses the Body Image in Adolescent Students].

Objective: To determine the validity and reliability of the 13-figure images scale (13-CS) and Standard Figural Stimuli (SFS) for the evaluation of body images in adolescent students from Bucaramanga.

Methods: A probabilistic sample with 189 students was evaluated with the two scales. Two weeks later, the valuation together with the size, weight, percentage of body fat, SCOFF questionnaire and Rosenberg self-esteem valuation was repeated.

Results: The average age was 14.1 years; 62.7% were women. The correlation of the 13-CS and SFS with body fat index, weight and body fat percentage was 0.61, 0.74, 0.40 and 0.72, 0.55, 0.45 respectively. The correlation of dissatisfaction with body image according to the SCOFF and the Rosenberg scales was 0.43 and 0.26 with the 13-CS; 0.50 and -0.23 with the SFS. The reproducibility shows that perceived and ideal figure was 0.93 and 0.90 with the 13-CS; and 0.85 and 0.78 with the SFS.

Conclusion: the concurrent validity of both scales was good. The reproducibility of the 13-CS was excellent while the SFS was good.
