In Spain there is a lack of specific instruments for the evaluation of deviance of the body image in adolescents. The aim of this research was to design and to validate a specific instrument for the evaluation of adolescent body dissatisfaction.
We carried out 6 studies utilizing 2 samples of 91 and 569 school adolescents aged 12 to 19 years. In studies 1, 2 and 3 we designed a questionnaire with items selected from the bibliography to analyze the discriminate power. In studies 4, 5 and 6, various indexes of reliability and validity were calculated and scores were typified.
The eventual questionnaire was made up of 32 items with 6 categories of responses. The reliability for the scale was: Cronbach's alpha for the whole sample, 0.91 (from 0.66 in the group of boys aged 17-19 years to 0.93 in the group of girls aged 14-16 years). The concurrent validity led to indexes between 0.67 and 0.89 using other instruments, and the factorial analysis showed 4 factors explaining 50.3% of the variance.
Our research provides a new instrument for the evaluation of body dissatisfaction. This instrument is designed specifically for adolescents and has a good reliability and validity when compared to other available instruments.
在西班牙，缺乏用于评估青少年身体意象偏差的特定工具。本研究的目的是设计并验证一种用于评估青少年身体不满的特定工具。
我们利用两组分别为91名和569名12至19岁在校青少年的样本进行了6项研究。在研究1、2和3中，我们从文献中选取项目设计了一份问卷，以分析其区分能力。在研究4、5和6中，计算了各种信度和效度指标，并对分数进行了分类。
最终的问卷由32个项目和6类回答组成。该量表的信度为：整个样本的克朗巴哈系数为0.91（17至19岁男性组为0.66，14至16岁女性组为0.93）。使用其他工具时，同时效度指标在0.67至0.89之间，因子分析显示4个因子解释了50.3%的方差。
我们的研究提供了一种用于评估身体不满的新工具。该工具专为青少年设计，与其他现有工具相比，具有良好的信度和效度。
