The effect of charity website design on perceived consistency and its consequences

초록

PurposeDrawing upon the consistency literature, the theory of visual rhetoric and social judgment of warmth and competence, this study examines the determinants and impacts of perceived interface design consistency in the context of charity websites.Design/methodology/approachTo identify design factors of perceived interface design consistency, this study separates charity website interface design into two aspects: main appeal design (i.e. appeal quality) and peripheral design (i.e. image type). The authors designed a two (appeal quality: low vs high) x three (image type: control vs adults vs children) controlled lab experiment to investigate the effects of various interface choices. A total of 217 subjects participated in the experiment. The authors used structural equation model (SEM) analysis and analysis of covariance (ANCOVA) to test the research hypotheses.FindingsThis study found that appeal quality and human images increase perceived interface design consistency. The authors also found that the relationship between appeal quality and perceived interface design consistency is moderated by image type. Finally, the authors showed that perceived interface design consistency increases perceived warmth and competence of charity websites, which in turn affect intention to use the website for donations.Originality/valueThe authors' findings provide novel insights for theory on consistency and interface design and practical implications for charity website designers by identifying determinants and consequences of perceived interface design consistency.
