What it measures

Three items assess whether a website provides interactive shopping decision-support features — brand comparison tools, preference-based questions, and personalised recommendations — to help consumers make more informed choices.

Response format

7-point Likert (1=strongly disagree, 7=strongly agree)

Scale items

• To recommend products, easy-to-answer questions are asked about my preferences.
• Useful shopping recommendations are made based on my personal information and preferences.

Full scale items shown. Always cite the original source when using this scale in research.

Usage notes & scoring

One of the Bart et al. (2005) website subscales, originally labelled 'advice'. Discriminant validity supported across subscales. Items assess the presence of features rather than satisfaction with them.
