Although a number of studies have investigated perceived self-efficacy, perceived benefits, and perceived barriers and their relationship to adolescents' participation in physical activity, the validity and reliability of the instruments used have not been consistently examined. The purpose of the present study was to develop culturally sensitive, reliable, and valid instruments to measure physical activity cognitions among Taiwanese adolescents.
The items generated for the instruments were drawn from a comprehensive literature review and a focus group interview. The instruments were translated using the back-translation technique and evaluated by a panel of experts. Psychometric testing was performed and confirmed with convenience samples of 110 and 969 Taiwanese adolescents.
Psychometric testing demonstrated satisfactory internal consistency and validity of the instrument for this group of Taiwanese adolescents. Cronbach's alpha's ranged from 0.79 to 0.90. Construct validity was supported by exploring the factor structure of the instrument using confirmatory factor analysis and correlation with the outcome variable of physical activity.
The study identified culturally sensitive items to measure physical activity cognitions in urban Taiwanese students in their early adolescence. Clinicians or practitioners can use the instruments developed and tested in this study for clinical assessment to identify risk factors for inactivity as well as for further research in similar populations.
尽管已有多项研究调查了自我效能感、感知到的益处和感知到的障碍及其与青少年参与体育活动的关系，但所使用工具的有效性和可靠性尚未得到一致检验。本研究的目的是开发具有文化敏感性、可靠且有效的工具，以测量台湾青少年的体育活动认知。
为工具生成的条目来自全面的文献综述和焦点小组访谈。使用回译技术对工具进行翻译，并由专家小组进行评估。进行了心理测量测试，并在110名和969名台湾青少年的便利样本中得到证实。
心理测量测试表明，该工具对于这组台湾青少年具有令人满意的内部一致性和有效性。克朗巴哈系数范围为0.79至0.90。通过使用验证性因素分析探索工具的因素结构以及与体育活动结果变量的相关性，支持了结构效度。
该研究确定了具有文化敏感性的条目，以测量台湾城市青少年早期的体育活动认知。临床医生或从业者可以使用本研究中开发和测试的工具进行临床评估，以确定不活动的风险因素以及在类似人群中进行进一步研究。
