With data from 400 HIV clients with fertility intentions and 57 HIV providers in Uganda, we evaluated the psychometrics of new client and provider scales measuring constructs related to safer conception methods (SCM) and safer conception counselling (SCC). Several forms of validity (i.e., content, face, and construct validity) were examined using standard methods including exploratory and confirmatory factor analysis. Internal consistency was established using Cronbach's alpha correlation coefficient. The final scales consisted of measures of attitudes towards use of SCM and delivery of SCC, including measures of self-efficacy and motivation to use SCM, and perceived community stigma towards childbearing. Most client and all provider measures had moderate to high internal consistency (alphas 0.60-0.94), most had convergent validity (associations with other SCM or SCC-related measures), and client measures had divergent validity (poor associations with depression). These findings establish preliminary psychometric properties of these scales and should facilitate future studies of SCM and SCC.
利用来自乌干达400名有生育意愿的艾滋病毒感染者和57名艾滋病毒服务提供者的数据,我们评估了新的服务对象和服务提供者量表的心理测量学特性,这些量表用于测量与更安全受孕方法(SCM)和更安全受孕咨询(SCC)相关的构念。使用包括探索性和验证性因素分析在内的标准方法检验了几种效度形式(即内容效度、表面效度和结构效度)。使用克朗巴赫α相关系数确定内部一致性。最终量表包括对使用SCM和提供SCC的态度测量,包括使用SCM的自我效能感和动机测量,以及社区对生育的耻辱感认知。大多数服务对象和所有服务提供者的测量指标具有中度到高度的内部一致性(α系数为0.60 - 0.94),大多数具有收敛效度(与其他SCM或SCC相关测量指标相关),服务对象测量指标具有区分效度(与抑郁相关性较差)。这些发现确立了这些量表初步的心理测量学特性,应有助于未来对SCM和SCC的研究。
