Clinical perfectionism has been found to be a risk and maintaining factor in eating disorders (EDs), compulsive exercise, and athlete burnout. This study investigated whether an unguided internet cognitive-behavioral treatment (ICBT) for perfectionism would reduce ED pathology, compulsive exercise, and burnout in individuals who engage in regular exercise.
Participants were randomly allocated to intervention (n = 38) or waitlist control (n =29). A generalized linear mixed model (GLMM) analysis was conducted pre and post treatment. A follow-up analysis was conducted with the intervention group at 3 and 6 months.
The intervention group experienced a significant reduction in perfectionism (FMPS-CM: F[1,117] = 17.53, p = < .001, Cohen's d = .82), ED symptomology (EDE-Q: F[1,55] = 7.27, p = .009,Cohen's d = .53) and compulsive exercise (CET: F[1,116] = 10.33, p < .001,Cohen's d = .63). The changes attained post-treatment were maintained within the intervention group at 3-month (FMPS-CM (t[1,100] = 3.67, p < . 001, Cohen's d = .85) (EDE-Q (t[1,50] = 2.20, p = .03, Cohen's d = 1.26) and 6-month follow-up (FMPS (t[1,100] = 2.74, p = 007, Cohen's d = .70) (EDE-Q (t[1,50] = 2.18, p = .03, Cohen's d = 1.26).
The results indicate unguided ICBT for perfectionism can have a significant impact on perfectionism, compulsive exercise, and ED symptomatology.
临床完美主义已被发现是饮食失调（EDs）、强迫性运动和运动员倦怠的风险和维持因素。本研究调查了针对完美主义的无指导互联网认知行为治疗（ICBT）是否会减少经常运动的个体的 ED 病理、强迫性运动和倦怠。
参与者被随机分配到干预组（n=38）或等待名单对照组（n=29）。治疗前和治疗后进行了广义线性混合模型（GLMM）分析。对干预组进行了 3 个月和 6 个月的随访分析。
干预组在完美主义（FMPS-CM：F[1,117]=17.53，p<0.001，Cohen's d=0.82）、饮食失调症状（EDE-Q：F[1,55]=7.27，p=0.009，Cohen's d=0.53）和强迫性运动（CET：F[1,116]=10.33，p<0.001，Cohen's d=0.63）方面均有显著降低。治疗后获得的变化在干预组内 3 个月时得到维持（FMPS-CM（t[1,100]=3.67，p<0.001，Cohen's d=0.85）（EDE-Q（t[1,50]=2.20，p=0.03，Cohen's d=1.26）和 6 个月随访（FMPS（t[1,100]=2.74，p=0.007，Cohen's d=0.70）（EDE-Q（t[1,50]=2.18，p=0.03，Cohen's d=1.26）。
结果表明，针对完美主义的无指导 ICBT 可以对完美主义、强迫性运动和 ED 症状产生重大影响。
