The shopping list in goal-directed shopping: scale development and validation

ABSTRACT

This paper aims to develop and validate a shopping list scale in a goal-directed shopping context based on three complementary study phases (and literature review): shopper interviews (exploratory stage to identify the items and dimensions), a pilot study with 162 respondents for scale purification, and a refined questionnaire administered to 213 respondents (to establish reliability, convergent, discriminant and nomological validity). An exploratory factor analysis shows that the items load onto four factors: memory aid, money controller, shopping controller, and deviation controller. We performed confirmatory factor analysis to test the model and check for reliability and validity of the anticipated scale. The model fit and reliability levels are acceptable, as are the convergent and discriminant validities of the scale. The scale is a second-order factor, thus satisfying nomological validity. The shopping list scale should be of interest to researchers and retail managers in exploring factors and outcomes of goal-directed shopper behaviour.

摘要

本文旨在开发和验证目标导向购物环境中的购物清单规模基于三个互补的研究阶段（和文献综述）：购物者访谈（探索阶段以确定项目和方面），一项针对162名受访者进行尺度净化的试点研究，以及对213名受访者进行的精确问卷调查（以建立可靠性，收敛性，判别性和法则验证）。 探索因子分析法表明，这些项目分为四个因素：记忆辅助，货币控制器，购物控制器和偏差控制器。我们进行了验证性因子分析以测试模型并检查预期规模的可靠性和有效性。模型拟合和可靠性水平是可接受的，尺度的收敛和判别验证也是可接受的。尺度表是二阶因子，因此满足了法则验证。在探索目标导向购物者行为的因素和结果时，研究人员和零售经理应该对购物清单尺度感兴趣。
