UNDERSTANDING THE DECISION TO USE CONDOMS--SUPPLEMENT

这项纵向研究将调查安全套使用的成员， 三个新出现的性传播疾病和艾滋病高危群体：青少年， 妓女和有多个性伴侣的异性恋成年人。 受试者将是金郡性传播疾病中心的客户 诊所和监狱卫生服务。 以菲什拜因和阿曾理论为指导 理性行动模型的具体结果和规范信念 与避孕套使用、使用避孕套的态度和规范相关， 将对使用避孕套的意愿进行衡量。 几种额外的态度 可能独立影响安全套使用的预测因素，包括 以前使用避孕套，感知控制，药物和酒精的使用，也将 被衡量。 使用避孕套的基本信念是 检查并比较各组和组内性别、年龄和 还将进行种族比较。 信仰的能力， 将比较各组预测意图的态度和规范。 我们将比较标准Fishbein模型和扩展模型 包括额外的态度预测，使用结构方程 建模技术 我们还将比较信仰和态度， 与新的性伴侣或固定的性伴侣使用避孕套。 第二份调查问卷将对相同的受试者进行管理， 月后 本调查问卷将重新评估 时间1，也会询问前三次避孕套的使用情况 个月 态度和意图变量集的能力， 预测随后的行为将被测试，并在 标准模型和扩展模型，包括额外的态度 预测因素，跨风险组和跨风险组内的亚组， 以及用于新的与固定的性伴侣，如上所述。 我们还将 能够将该时间2数据与时间1数据进行比较，并跟踪 随着时间的推移，这些高危人群的特定信念和态度。 这项研究的结果应该建议具体的态度改变 * 采取干预措施，增加安全套的使用， 这些高危人群。 标准与扩展Fishbein的测试 该模型还将有利于性病和艾滋病研究，以及 其他行为控制的健康威胁，通过促进 建立一个有前途的决策模式。

This longitudinal study will investigate condom use among members of three emerging high-risk groups for STDs and AIDS: adolescents, prostitutes, and heterosexual adults with multiple sexual partners. Subjects will be clients of the King County Sexually Transmitted Disease Clinic and Jail Health Services. Guided by Fishbein and Ajzen's Theory of Reasoned Action model, the specific outcome and normative beliefs associated with condom use, attitudes and norms toward using condoms, and intention to use condoms will be measured. Several extra-attitudinal predictors that may contribute independently to condom use, including prior condom use, perceived control, and drug and alcohol use, will also be measured. The beliefs underlying intention to use condoms will be examined and compared across groups, and within-group sex, age, and ethnicity comparisons will also be made. The ability of beliefs, attitudes and norms to predict intention for each group will be compared. We will compare the standard Fishbein model with an expanded model including extra-attitudinal predictors, using structural equation modeling techniques. We will also compare beliefs and attitudes toward using condoms with new vs. steady sexual partners. A second questionnaire will be administered to the same subjects three months later. This questionnaire will reassess the variables measured at time 1, and will also ask about use of condoms in the preceding three months. The ability of the set of attitudinal and intention variables to predict subsequent behavior will be tested, and comparisons made between the standard model and the expanded model including extra-attitudinal predictors, across risk groups and across sub-groups within risk groups, and for use with new vs. steady sexual partners, as above. We will also be able to compare this time 2 data with time 1 data and track changes in specific beliefs and attitudes in these high risk groups over time. The findings of this study should suggest specific attitude-change interventions that will lead to increased condom use among members of these high-risk groups. Tests of the standard vs. expanded Fishbein model will also benefit STD and AIDS research, as well as research on other behaviorally-controlled threats to health, by contributing to the development of a promising model of decision-making.
