Abstract

Background: Exercise addiction (EA) is manifested by loss of control over exercising and experiencing numerous negative consequences. One of the most commonly used psychometric instruments to assess the risk of exercise addiction is the six-item Exercise Addiction Inventory (EAI). The present study translated and validated the EAI into Polish and evaluated its psychometric properties.

Participants and procedure: The study included 858 adult participants (54% female) aged between 18 and 69 years (M = 35.20, SD = 9.54) who exercised recreationally. Participants completed the EAI along with exercise-specific questions and basic demographics. Additionally, a subsample (n = 214) completed the Exercise Dependence Scale-Revised. Confirmatory factor analysis (CFA) was conducted to assess the construct validity of the Polish EAI. Convergent and criterion validity, as well as reliability, were also assessed.

Results: The CFA confirmed the one-factor model with good fit statistics (comparative fit index and Tucker-Lewis index > .95, root-mean square error of approximation < .08). The EAI was invariant between men and women. Convergent validity was adequate. The scale's internal consistency was excellent (Cronbach's α = .91, McDonald's ω = .91, and composite reliability = .91).

Conclusions: The present study successfully validated the EAI among Polish adults. The results provide robust evidence concerning the scale's reliability, construct validity, and convergent validity, enabling further research on exercise addiction in Poland.

波兰版运动成瘾量表（EAI-PL）的验证与心理测量学评价。

背景：运动成瘾（EA）表现为对运动失去控制并经历许多负面后果。最常用的评估运动成瘾风险的心理测量工具之一是六项运动成瘾量表（EAI）。本研究将EAI翻译并验证为波兰语，并评估其心理测量特性。参与者和程序：该研究包括858名年龄在18至69岁之间（M = 35.20, SD = 9.54）进行娱乐性锻炼的成年参与者（54%为女性）。参与者完成了EAI以及特定运动问题和基本人口统计数据。此外，一个子样本（n = 214）完成了运动依赖量表-修订版。采用验证性因子分析（CFA）来评估波兰EAI的结构效度。还评估了收敛效度和标准效度以及信度。结果：CFA证实单因素模型具有良好的拟合统计量（比较拟合指数和Tucker-Lewis指数>.95，近似均方根误差< .08）。EAI在男性和女性之间是不变的。收敛效度是足够的。量表的内部一致性极好（Cronbach’s α = 0.91, McDonald’s ω = 0.91，复合信度= 0.91）。结论：本研究成功地验证了波兰成年人的EAI。研究结果为量表的信度、结构效度和收敛效度提供了有力的证据，为进一步研究波兰的运动成瘾提供了依据。
