两项研究调查了使用Fishbein-Ajzen期望值态度模型所产生的方法学问题。明确比较了不同的期望值模型-基于评分程序（信念的双极与单极评分）和组合规则（值和期望分量的乘法与加法）的操作。虽然他们使用了不同的态度项目和样本，但两项研究使用乘法/双极信念模型与总体态度的相关性显著低于使用乘法/单极信念和加法模型。信念分量的线性变换对乘法模型有显着影响，但对加法模型没有影响。研究结果进行了讨论，在其实践和理论的重要性。
Two studies investigated methodological issues arising from the use of the Fishbein‐Ajzen expectancy‐value model of attitudes. Different expectancy‐value models— based on manipulations of scoring procedure (bi‐polar vs. uni‐polar scoring of beliefs) and combinatorial rule (multiplication vs. addition of value and expectancy components) ‐were explicitly compared. Although they used different attitudinal items and samples, both studies obtained significantly lower correlations with overall attitude by using the multiplicative/bi‐polar belief model than by using multiplicative/uni‐polar belief and additive models. Linear transformations of the belief component had a dramatic effect on the multiplicative model, but had no impact on the additive model. The findings are discussed in terms of their practical and theoretical importance.
