UNASSIGNED: In total, 74 subjects were recruited into this three-month randomized trial and divided into intervention and control groups receiving, respectively, capsules containing 3 g 80% CLA per day and capsules containing 3 g of sunflower oil. The following psychological tests were performed before the intervention: Multidimensional Health Locus of Control scale, Acceptance of Illness Scale, Satisfaction with Life Scale (SWLS), General Self Efficacy Scale (GSES), Health Behavior Inventory scale and Life Orientation Test (LOT-R).
UNASSIGNED: A total of 60 women completed the study and the subjects who dropped out obtained higher scores in the GSES (p = 0.0490) and the LOT-R (p = 0.0087) tests than subjects who completed the trial. Besides, multivariate linear regression demonstrated that the SWLS test (p = 0.0345) results were independent predictors of body weight changes.
UNASSIGNED: In conclusion, psychological factors like self-efficacy and optimism may be associated with a higher risk of withdrawal from the study, while satisfaction with life may have an impact on the effectiveness of body weight reduction.Clinical trial registration: [https://drks.de/search/en], identifier [DRKS00010462].
■总共,这项为期三个月的随机试验招募了74名受试者,分为干预组和对照组,分别,每天含有3克80%CLA的胶囊和含有3克葵花籽油的胶囊。干预前进行了以下心理测试:多维健康控制源量表,接受疾病量表,生活满意度量表(SWLS),一般自我效能感量表(GSES),健康行为量表和生活取向测试(LOT-R)。
共有60名女性完成了这项研究,退学的受试者在GSES(p=0.0490)和LOT-R(p=0.0087)测试中获得了比完成试验的受试者更高的分数。此外,多元线性回归表明,SWLS检验(p=0.0345)结果是体重变化的独立预测因子。
■总而言之,自我效能感和乐观等心理因素可能与退出研究的风险较高有关,而对生活的满意度可能会影响减肥的有效性。临床试验注册:[https://drks。de/search/en],标识符[DRKS00010462]。
