A psychometric technique, functional measurement, was used to measure the preferences of 77 persons for hypothetical health care providers identified by various levels of cost, travel time, and waiting time; responses were subjected to analysis of variance and graphic analysis to determine the functional relation by which respondents combined the three attributes in arriving at their preferences. Both modes of analysis suggested multiplicative decision models, but these yielded lower values of R2 than did linear models derived for comparison. Respondents were grouped by the proportion of response variance that was explained by each of the three attributes, and decision models were derived for each group. Discriminant analysis of socioeconomic characteristics of the respondents identified the variables that distinguished the groups and contributed to forming their preferences.
一种心理测量技术,即功能测量,被用于测量77人对由不同成本、出行时间和等待时间所确定的假设医疗服务提供者的偏好;对回答进行方差分析和图形分析,以确定受访者在形成偏好时组合这三个属性的功能关系。两种分析模式都表明是乘法决策模型,但这些模型的R2值比为比较而推导的线性模型要低。根据三个属性各自解释的回答方差比例对受访者进行分组,并为每个组推导决策模型。对受访者社会经济特征的判别分析确定了区分这些组并有助于形成他们偏好的变量。
