Measurement of condom attitudes, norms, and self-efficacy is variable, reducing research generalizability. The purpose of this study was to assess reliability and construct validity of measures of condom attitudes, norms, and self-efficacy across 3,989 youth. Data were collected at computer kiosks and on the Internet. Analyses included internal consistency reliability assessments and exploratory and confirmatory factor analyses of three constructs in a 32-item a priori instrument. Reliability estimates ranged between 0.68 and 0.89, and goodness of fit indices all exceeded 0.90. Factor analysis results supported the compatibility of the items from the three subscales with their conceptual domains. Final scales include measures of positive and negative outcome expectancies related to condom use, peer and partner condom norms, self-efficacy for condom negotiation, and self-efficacy for condom use. These measures of condom attitudes, norms, and self-efficacy can be employed for assessments to improve standardization of measures and generalizability of research, particularly related to HIV prevention.
对避孕套态度、规范和自我效能的测量存在差异，这降低了研究的普遍性。本研究的目的是评估3989名青少年中避孕套态度、规范和自我效能测量方法的信度和结构效度。数据通过电脑亭和互联网收集。分析包括内部一致性信度评估，以及对一个包含32个条目的先验工具中三个结构的探索性和验证性因素分析。信度估计值在0.68至0.89之间，拟合优度指数均超过0.90。因素分析结果支持三个分量表中的条目与其概念领域的兼容性。最终量表包括与避孕套使用相关的积极和消极结果预期、同伴和伴侣的避孕套规范、避孕套谈判自我效能以及避孕套使用自我效能的测量。这些避孕套态度、规范和自我效能的测量方法可用于评估，以提高测量的标准化和研究的普遍性，特别是与艾滋病毒预防相关的研究。
