OBJECTIVE
Compulsive exercise describes a rigid, driven urge to exercise that has been reported in different populations, including eating disorder patients. This compulsion can develop at an early age and yet the measurement of compulsive exercise in adolescents is limited by inappropriate assessment techniques. This study aimed to psychometrically evaluate the Compulsive Exercise Test (CET) in a sample of adolescents.
METHODS
The sample consisted of 1012 adolescents aged 12-14 years old, who completed the CET, the Commitment to Exercise Scale (CES), and selected subscales from the Eating Disorder Inventory-2 (EDI-2).
RESULTS
Results confirmed the original five-factor solution of the CET. The CET's concurrent validity with the CES, as well as the convergent validity with the EDI-2, was established. The CET was not strongly related to exercise frequency.
CONCLUSION
The CET appears to be valid and reliable for use with adolescents. Replication with an adolescent clinical eating disorder sample is now required.
目的
强迫性运动是指一种强烈的、强制性的运动欲望，在不同人群中都有报道，包括饮食障碍患者。这种强迫性运动可能在早期就会出现，而青少年强迫性运动的测量受到不适当评估技术的限制。本研究旨在对青少年群体中使用的强迫性运动测试（CET）进行心理测量评估。
方法
该样本由 1012 名 12-14 岁的青少年组成，他们完成了 CET、锻炼承诺量表（CES）和饮食障碍问卷-2（EDI-2）的部分分量表。
结果
结果证实了 CET 的原始五因素结构。CET 与 CES 的同时效度，以及与 EDI-2 的收敛效度都得到了确立。CET 与运动频率的相关性并不强。
结论
CET 似乎对青少年有效且可靠。现在需要用青少年临床饮食障碍样本进行复制。
