Reliable and valid scale measures of barriers to condom use are not available for young black men who have sex with men (YBMSM). The purpose of this study was to evaluate the Condom Barriers Scales for application with YBMSM.
A clinic-based sample of 600 YBMSM completed a computer-assisted self-interview. The primary measure was a 14-item abbreviated version of the Condom Barriers Scale. Reliability and criterion validity were assessed.
All 3 subscales were reliable: partner-related barriers (Cronbach α=0.73), sensation-related barriers (α=0.70), and motivation-related barriers (α =0.81). A complete absence of barriers was common: 47.0% (partner-related), 30.7% (sensation-related), and 46.5% (motivation-related). Dichotomized subscales were significantly associated with reporting any condomless insertive anal sex (all Ps < 0.001) and any condomless receptive anal sex (all Ps < 0.001). The subscales were significantly associated with these measures of condomless sex preserved at a continuous level (all Ps <0.001, except for sensation barriers associated with condomless receptive anal sex = 0.03). Further, the subscales were significantly associated with reporting any condom use problems (all Ps <0.001) and a measure of condomless oral sex (all Ps <0.001, except for partner-related barriers=0.31). Finally, the sensation-related barriers subscale was significantly associated with testing positive for Chlamydia and/or gonorrhea (P=0.049).
The 3 identified subscales yielded adequate reliability and strong evidence of validity, thereby suggesting the utility of these brief measures for use in observational and experimental research with YBMSM.
对于与男性发生性关系的年轻黑人男性（YBMSM），尚无可靠且有效的衡量避孕套使用障碍的量表。本研究旨在评估避孕套障碍量表在YBMSM中的应用情况。
选取600名YBMSM作为基于诊所的样本，完成计算机辅助的自我访谈。主要测量工具为14项的避孕套障碍量表简版。评估了其信度和效标效度。
所有3个分量表均具有可靠性：伴侣相关障碍（Cronbach α = 0.73）、感觉相关障碍（α = 0.70）和动机相关障碍（α = 0.81）。完全没有障碍的情况很常见：伴侣相关障碍为47.0%，感觉相关障碍为30.7%，动机相关障碍为46.5%。二分后的分量表与报告任何无保护插入式肛交行为（所有P值<0.001）以及任何无保护接受式肛交行为（所有P值<0.001）均显著相关。分量表与这些无保护性行为的测量指标在连续水平上也显著相关（所有P值<0.001，但感觉障碍与无保护接受式肛交行为的相关性P值 = 0.03）。此外，分量表与报告任何避孕套使用问题（所有P值<0.001）以及无保护口交行为的测量指标（所有P值<0.001，但伴侣相关障碍的P值 = 0.31）均显著相关。最后，感觉相关障碍分量表与衣原体和/或淋病检测呈阳性显著相关（P = 0.049）。
所确定的3个分量表具有足够的信度和有力的效度证据，这表明这些简短测量工具在针对YBMSM的观察性和实验性研究中具有实用性。
