The impact of regulatory focus and word of mouth valence on search and experience attribute evaluation
通过三个实验研究了调节焦点（促进vs预防）、属性类型（搜索vs体验）和口碑效价（正面vs负面）如何共同影响消费者对服务和产品的购买决策。
Purpose This paper aims to investigate the direct and interactive effects of regulatory focus (promotion versus prevention), attribute type (search versus experience) and word of mouth valence (positive versus negative) on consumption decision for a service and a product. Design/methodology/approach Three empirical studies (two laboratories and a field experiment) using “university” and “mobile phone” as the research setting were used to test the key hypotheses. Findings Promotion (prevention)-focused subjects preferred experience (search) attributes over their counterparts while making consumption decision. This preference was further reinforced for both promotion and prevention-focused people under positive word of mouth. Under negative word of mouth, in comparison to their counterparts, promotion-focused people still retained their preference for experience attributes, whereas prevention-focused subjects reversed their preference and maintained status quo. Research limitations/implications Future research may validate and extend authors’ findings by looking into the underlying process or studying additional word of mouth variables that may moderate the current findings. Practical implications The findings will help managers devise a range of marketing strategies in the areas of advertising and product positioning, especially for products/services that are showcased in terms of experience and search attributes. Originality/value The current research is novel as no prior research has proposed and tested the two-way interaction between regulatory focus and search/experience attributes, or its further moderation by word of mouth valence.
