To evaluate reliability and validity of the Chinese version of the Measure of Audiologic Rehabilitation Self-Efficacy for Hearing Aids (C-MARS-HA) and to analyze self-efficacy of Chinese hearing aid users.
The Brislin translation model was strictly adopted to modify the C-MARS-HA. Participants included 134 hearing aid users aged 20-98. Hearing aid users were surveyed through questionnaire interviews regarding self-efficacy and overall satisfaction with hearing aids. Reliability and validity of the questionnaires were analyzed. Descriptive statistical and correlation analyses were conducted on the total score and four factors of the C-MARS-HA and overall satisfaction.
In reliability analysis, Cronbach' s α, Spearman-Brown, and Guttman split-half coefficients of the overall and four factors were all greater than 0.6, indicating that C-MARS-HA has acceptable reliability. In validity analysis, C-MARS-HA consisted of 24 items across 4 factors (basic handling, aided listening, adjustment and advanced handling) and had acceptable content validity. Exploratory factor analysis yielded with a four-factor solution, explaining more than 40% of the total variance and the loading coefficient for each of the 24 items was above 0.4, indicating that C-MARS-HA had good construct validity. Average scores for basic handling and adjustment were at least 80%, whereas average scores for aided listening, advanced handling, and total scores were less than 80%. A total of 65.67% of users had an overall satisfaction rate of 80%. A significant positive correlation (p < 0.001) was found between the total score of the questionnaire, the scores of the four factors, and overall satisfaction.
The reliability and validity of the C-MARS-HA is acceptable. This questionnaire can be used for clinical evaluation of self-efficacy among Chinese hearing aid users.
评估中文版助听器听觉康复自我效能量表（C-MARS-HA）的信效度，并分析中国助听器使用者的自我效能。
严格采用 Brislin 翻译模型对 C-MARS-HA 进行修订。研究对象包括 134 名年龄在 20 至 98 岁之间的助听器使用者。通过问卷调查访谈的方式，对助听器使用者的自我效能及对助听器的总体满意度进行调查。分析问卷的信效度。对 C-MARS-HA 的总分、四个因子以及总体满意度进行描述性统计分析和相关性分析。
在信度分析中，总量表及四个因子的 Cronbach's α系数、Spearman-Brown 系数和 Guttman 分半系数均大于 0.6，表明 C-MARS-HA 具有可接受的信度。在效度分析中，C-MARS-HA 由 4 个因子（基本操作、助听、调试和高级操作）共 24 个条目组成，具有可接受的内容效度。探索性因子分析得到四因子模型，解释总方差的 40%以上，24 个条目的载荷系数均大于 0.4，表明 C-MARS-HA 具有良好的结构效度。基本操作和调试的平均分至少为 80%，而助听、高级操作及总分的平均分低于 80%。共有 65.67%的使用者总体满意度达到 80%。问卷总分、四个因子得分与总体满意度之间存在显著正相关（p < 0.001）。
C-MARS-HA 的信效度可接受。该问卷可用于中国助听器使用者自我效能的临床评估。
