There are not many valid instruments to quickly and easily identify body dissatisfaction in adolescents. Most studies have used the Stunkard Rating Scale to assess body image. Nevertheless, this scale has been described as too abrupt and crude for adolescents.
Was to validate the body image dimensional assessment (BIDA) questionnaire in a sample of adolescents from Secondary schools of Spain.
The BIDA consists of four items to answer with reference to a series of four silhouettes using a numeric scale that allows the quantification of the degree of body dissatisfaction (BD), sexual body dissatisfaction (SxBD), comparative body dissatisfaction (CBD) and the calculation of the final body dissatisfaction index (BDIndex). The sample included 2059 adolescents, 1132 males and 929 females aged 13.10 ± 0.89. Participants answered the BIDA and then their anthropometrics measurements were taken.
Reliability test, a convergent test and confirmatory factorial analysis were conducted to validate BIDA instrument. A single factor structure emerged from confirmatory factorial analysis; the BIDA demonstrated adequate internal consistency in adolescents: (CFI > 0.90, TLI > 0.90, α > 0.80). Significant correlations (p < 0.001) emerged between the BIDA indices and all the anthropometric measures.
The BIDA questionnaire is a valid and reliable instrument to evaluate body dissatisfaction in Spanish adolescents.

目前，很少有有效的工具可以快速、轻松地识别青少年的身体不满。大多数研究都使用 Stunkard 评分量表来评估身体形象。然而，该量表被描述为对青少年来说过于生硬和粗糙。
在西班牙中学的青少年样本中验证身体形象维度评估（BIDA）问卷。
BIDA 由四个项目组成，要求参与者参照一系列四个轮廓图，使用数字量表回答，该量表可量化身体不满程度（BD）、性身体不满（SxBD）、比较身体不满（CBD）和计算最终身体不满指数（BDIndex）。样本包括 2059 名年龄在 13.10±0.89 岁的青少年，其中 1132 名男性和 929 名女性。参与者回答 BIDA 问卷，然后测量他们的人体测量学指标。
进行了可靠性测试、收敛性测试和验证性因子分析，以验证 BIDA 工具。验证性因子分析得出了单一因素结构；BIDA 在青少年中表现出足够的内部一致性：（CFI>0.90，TLI>0.90，α>0.80）。BIDA 指数与所有人体测量指标之间均存在显著相关性（p<0.001）。
BIDA 问卷是评估西班牙青少年身体不满的有效、可靠工具。
