This study investigated variable to differentiate two groups of adolescent girls, one consuming a good quality diet and one consuming a poor diet. Of the initial sample of 276 adolescent girls surveyed, the 50 girls with the best and 50 with the worst diets were identified. No differnece between the groups was found on three personality traits (self-esteem, social recognition, and enerty level). The use of a multivariate stepwise discriminant function analysis resulted in the selection of three variables as the strongest predictors of dietary quality: hours per day spent in - inactive pursuits, ideal body image choices, and past dieting attempts.
本研究调查了用于区分两组青春期女孩的变量,一组食用优质饮食,另一组食用不良饮食。在最初接受调查的276名青春期女孩样本中,确定了饮食最佳的50名女孩和饮食最差的50名女孩。两组在三种人格特质(自尊、社会认可度和能量水平)上未发现差异。使用多元逐步判别函数分析后,选择了三个变量作为饮食质量的最强预测指标:每天花在非活动追求上的小时数、理想身体形象选择和过去的节食尝试。
