This study sought to extend the use of a Web-based HIV Testing Belief Inventory (wHITBI), developed and validated in a majority White university in the southeastern United States, to students attending historically Black colleges and universities (HBCUs). The 19-item wHITBI was reviewed by experts to qualitatively assess its construct validity, clarity, relevancy, and comprehensiveness to HBCU students. Participants were recruited from 15 HBCUs (valid N = 372). Mean age was 20.5 years (SD = 2.4), 80% were females, 92% were heterosexual-oriented, and 58% had prior HIV test(s). Reliability coefficients revealed satisfactory internal consistencies (Cronbach's alphas: .58 approximately .85). Confirmatory factor analysis showed that items were loaded consistently with the four constructs: perceived benefits, concerns of HIV risk, stigma, and testing availability/accessibility. Data indicated good model fits (RMSEA = .06; CFI = .93; IFI = .93; RMS = .07), with all items loaded significantly. Findings showed that the psychometrics of wHITBI appears to maintain its integrity in this sample with satisfactory reliability coefficients and validities.
本研究旨在将基于网络的艾滋病毒检测信念量表(wHITBI)的应用范围扩大到就读于历史悠久的黑人学院和大学(HBCUs)的学生,该量表是在美国东南部一所白人占多数的大学开发并验证的。由专家对包含19个条目的wHITBI进行审查,以定性评估其对HBCU学生的结构效度、清晰度、相关性和全面性。参与者从15所HBCUs招募(有效样本量N = 372)。平均年龄为20.5岁(标准差 = 2.4),80%为女性,92%为异性恋取向,58%曾接受过艾滋病毒检测。信度系数显示出令人满意的内部一致性(克朗巴哈系数:约0.58至0.85)。验证性因素分析表明,各条目与四个结构一致:感知益处、对艾滋病毒风险的担忧、耻辱感以及检测的可及性/可获得性。数据表明模型拟合良好(RMSEA = 0.06;CFI = 0.93;IFI = 0.93;RMS = 0.07),所有条目载荷均显著。研究结果表明,wHITBI的心理测量学特性在该样本中似乎保持了其完整性,具有令人满意的信度系数和效度。
