BACKGROUND
To reliably evaluate the acceptance and use of computer-based prostate cancer decision aids (CBDAs) for African-American men, culturally relevant measures are needed. This study describes the development and initial psychometric evaluation of the 24-item Computer-Based Prostate Cancer Screening Decision Aid Acceptance Scale among 357 African-American men.
METHODS
Exploratory factor analysis (EFA) with maximum likelihood estimation and polychoric correlations followed by Promax and Varimax rotations.
RESULTS
EFA yielded three factors: Technology Use Expectancy and Intention (16 items), Technology Use Anxiety (5 items), and Technology Use Self-Efficacy (3 items) with good to excellent internal consistency reliability at .95, .90, and .85, respectively. The standardized root mean square residual (0.035) indicated the factor structure explained most of the correlations.
CONCLUSIONS
Findings suggest the three-factor, 24-item Computer-Based Prostate Cancer Screening Decision Aid Acceptance Scale has utility in determining the acceptance and use of CBDAs among African-American men at risk for prostate cancer. Future research is needed to confirm this factor structure among socio-demographically diverse African-Americans.
背景
为了可靠地评估计算机前列腺癌决策辅助工具（CBDAs）在非裔美国男性中的接受度和使用情况，需要使用具有文化相关性的测量方法。本研究描述了 357 名非裔美国男性中 24 项基于计算机的前列腺癌筛查决策辅助工具接受度量表的开发和初步心理计量学评估。
方法
采用最大似然估计和偏相关的探索性因子分析（EFA），随后进行 Promax 和 Varimax 旋转。
结果
EFA 产生了三个因素：技术使用期望和意图（16 项）、技术使用焦虑（5 项）和技术使用自我效能（3 项），其内部一致性信度分别为.95、.90 和.85，非常好。标准化根均方残差（0.035）表明，该因子结构解释了大部分相关性。
结论
研究结果表明，三因素、24 项基于计算机的前列腺癌筛查决策辅助工具接受度量表可用于确定具有前列腺癌风险的非裔美国男性对 CBDAs 的接受度和使用情况。需要进一步的研究来确认这一因子结构在社会人口统计学上多样化的非裔美国人中是否适用。
