This work proposes that trait body dissatisfaction rests on two dissociable components: 1) frequency of body dissatisfaction episodes, and 2) duration of such episodes, with higher trait body dissatisfaction resulting from more frequent and/or prolonged episodes. The current research aimed to develop a measure of these two dimensions (i.e., the Body Dissatisfaction Frequency Duration Questionnaire; BDFDQ) and test this theoretical model by investigating whether body dissatisfaction frequency and duration 1) were structurally dissociable, 2) meaningfully dissociable, and 3) each associated with different aspects of disordered eating behavior. Study 1 (N = 300, 42% women) developed the BDFDQ and showed that frequency and duration are structurally dissociable. Study 2 (N = 400, 50% women) showed that the two-factor model was invariant across gender and both subscales showed good psychometric properties of reliability and validity. Results further supported that frequency and duration are meaningfully dissociable by revealing that each component accounted for unique variance in trait body dissatisfaction. Study 3 (N = 279, 77% women) replicated Study 2 findings and established that frequency and duration subscales each associated with different aspects of disordered eating behavior. Together, findings imply that body dissatisfaction frequency and duration represent two separable dimensions underlying trait body dissatisfaction.

身体不满的频率和持续时间:特质身体不满的可分离维度

这项工作提出,特质身体不满意取决于两个可分离的成分:1)身体不满意发作的频率,以及 2)此类发作的持续时间,更高的特质身体不满意是由更频繁和/或更长的发作引起的。目前的研究旨在开发这两个维度的测量方法(即身体不满意频率持续时间问卷;BDFDQ),并通过调查身体不满意频率和持续时间 1) 在结构上是否可分离、2) 可有意义地分离和 3 来测试该理论模型) 每个都与饮食失调行为的不同方面有关。研究 1(N  = 300,42% 的女性)开发了 BDFDQ,并表明频率和持续时间在结构上是可分离的。研究 2 ( N = 400, 50% 的女性) 表明双因素模型在性别之间是不变的,并且两个分量表都显示出良好的信度和效度的心理测量特性。结果进一步支持了频率和持续时间是有意义的分离,因为它揭示了每个成分都解释了特质体不满的独特差异。研究 3(N  = 279,77% 的女性)复制了研究 2 的结果,并确定频率和持续时间分量表分别与饮食失调行为的不同方面相关。总之,研究结果表明身体不满意的频率和持续时间代表了特质身体不满意的两个可分离的维度。
