The primary purpose of the study was to assess the one-factor and two-factor structure of the Injury Psychological Readiness to Return to Sport Scale (IPRRS) in an injured physically active population using confirmatory factor analysis (CFA) procedures and assess group (ie, sex, age, injury type, athlete status) and longitudinal differences using structural equation modelling (eg, invariance testing).
The non-experimental study included a sample of 629 physically active individuals who suffered a musculoskeletal injury who sought treatment at an outpatient integrated sport medicine and rehabilitation therapy clinic. Participants filled out a questionnaire packet at three time points. Data analysis included a CFA and multigroup and longitudinal invariance.
Sample mean age was 26.3 years, with females comprising 49.5%. Chronic injuries represented 29.6% of the sample and 35.0% were classified as competitive athletes. A six-item, one-factor model was confirmed in the sample with factor loadings ranging from 0.67 to 0.86. Multigroup and longitudinal invariance were established. Multigroup invariance demonstrated null differences between sex and injury type, and statistical differences between age and athlete status subgroups. Longitudinal invariance demonstrated a statistically significant increase in psychological readiness over time.
The findings support the use of the IPRRS as a tool to measure aspects of psychological readiness. Clinicians and researchers can use the IPRRS to assess interventions in future research.
本研究的主要目的是使用验证性因素分析（CFA）程序评估受伤的体育活动人群中运动损伤心理恢复准备量表（IPRRS）的单因素和双因素结构，并使用结构方程模型（如不变性检验）评估组间差异（即性别、年龄、损伤类型、运动员状态）和纵向差异。
这项非实验性研究纳入了629名患有肌肉骨骼损伤的体育活动个体样本，他们在一家门诊综合运动医学与康复治疗诊所寻求治疗。参与者在三个时间点填写了一组问卷。数据分析包括CFA以及多组和纵向不变性分析。
样本的平均年龄为26.3岁，女性占49.5%。慢性损伤占样本的29.6%，35.0%被归类为竞技运动员。在样本中确认了一个六项单因素模型，因素载荷范围为0.67至0.86。建立了多组和纵向不变性。多组不变性表明性别和损伤类型之间无差异，年龄和运动员状态亚组之间存在统计学差异。纵向不变性表明心理准备随时间有统计学显著增加。
研究结果支持将IPRRS用作测量心理准备方面的工具。临床医生和研究人员可在未来研究中使用IPRRS评估干预措施。
