目的：描述计算机自我效能量表在临床环境中使用的修改，并报告修改后的量表的信度和结构效度。研究方法：修改了计算机自我效能量表，使其适用于临床环境（用于使用日常技术的老年人或残疾人）。修改后的规模进行了试点，然后在澳大利亚住院康复设置（n = 88），以确定内部一致性使用克朗巴赫的α系数与患者进行测试。结构效度通过量表与年龄和技术使用的相关性进行评估。采用主成分分析进行因子分析，以确定规模内的重要结构。结果：修订后的计算机自我效能量表具有较高的内部一致性，标准化α系数为0.94。该量表中的两个结构是显而易见的;单独使用技术，以及在他人的支持下使用技术。量表得分与年龄和使用频率的一些技术，从而支持结构效度。结论：修改后的计算机自我效能量表已经证明了测量老年人或残疾人使用日常技术时的自我效能的信度和结构效度。该工具有可能帮助临床医生识别可能更愿意使用新技术来保持独立性的老年患者。
Purpose: To describe a modification of the computer self efficacy scale for use in clinical settings and to report on the modified scale's reliability and construct validity. Methods: The computer self efficacy scale was modified to make it applicable for clinical settings (for use with older people or people with disabilities using everyday technologies). The modified scale was piloted, then tested with patients in an Australian inpatient rehabilitation setting (n = 88) to determine the internal consistency using Cronbach's alpha coefficient. Construct validity was assessed by correlation of the scale with age and technology use. Factor analysis using principal components analysis was undertaken to identify important constructs within the scale. Results: The modified computer self efficacy scale demonstrated high internal consistency with a standardised alpha coefficient of 0.94. Two constructs within the scale were apparent; using the technology alone, and using the technology with the support of others. Scores on the scale were correlated with age and frequency of use of some technologies thereby supporting construct validity. Conclusions: The modified computer self efficacy scale has demonstrated reliability and construct validity for measuring the self efficacy of older people or people with disabilities when using everyday technologies. This tool has the potential to assist clinicians in identifying older patients who may be more open to using new technologies to maintain independence.
