Motivational factors are among the most important determinants of undertaking and participating in physical activity. An adequate measurement of motivation and the assessment of its initial characteristics form the basis for possible further practical interventions of a compensatory or promotional nature. Considering the above, the main aim of this study was to assess the psychometric properties of the Polish version of the Goal Orientation in Exercise Measure (GOEM), and to determine the association between the task and the ego orientations and selected components of physical activity, i.e., frequency of undertaking, declared time per session and time spent on physical activity. In addition to the typical indices of psychometric assessment, an analysis of the reliability of test items by applying the item response theory (IRT) model was also presented. The study included 318 individuals (173 females, 145 males), aged 21 years on average, undertaking recreational physical activity. The GOEM scale by Petherick and Markland (2008) was used. The model of the Polish version of the GOEM scale fitted the empirical data well (CFI = 0.955). Satisfactory reliability indices were also obtained (task subscale: alpha = 0.83, omega = 0.83; ego subscale: alpha = 0.86, omega = 0.86). Reliability, as assessed by the test-retest method, was ICC = 0.80 for the task subscale and ICC = 0.87 for the ego subscale. The IRT analysis showed that the ego subscale was more precise in the middle level of the trait, while the task subscale provided more information in the low and middle level of the trait and relatively little information in the high level of the trait. The positive associations of the task subscale with the frequency of physical activity and the time spent in a single exercise session were also noted.
动机因素是开展和参与体育活动的最重要决定因素之一。对动机进行充分测量并评估其初始特征，是进行可能的补偿性或促进性进一步实际干预的基础。考虑到上述情况，本研究的主要目的是评估波兰语版运动目标定向量表（GOEM）的心理测量特性，并确定任务定向和自我定向与体育活动的选定组成部分之间的关联，即开展频率、每次训练宣称的时间以及体育活动所花费的时间。除了心理测量评估的典型指标外，还通过应用项目反应理论（IRT）模型对测试项目的信度进行了分析。该研究纳入了318名平均年龄为21岁、进行休闲体育活动的个体（173名女性，145名男性）。使用了Petherick和Markland（2008年）编制的GOEM量表。波兰语版GOEM量表模型与实证数据拟合良好（CFI = 0.955）。还获得了令人满意的信度指标（任务子量表：α = 0.83，ω = 0.
