Personal Involvement Inventory

What it measures

The most widely used measure of consumer involvement — the perceived relevance of an object based on inherent needs, values, and interests. Uses bipolar adjective pairs (e.g., important/unimportant) to capture overall product or brand involvement. Adaptable to any product category, advertisement, or purchase decision.

Response format

Semantic differential (7-point bipolar adjective pairs); total 20–140; higher = greater involvement
