The NIP is a balanced adaptation of Laurent and Kapferer's (1985) Consumer Involvement Profiles (CIP), developed to address the original CIP's unequal facet item counts (particularly the two-item Sign Value facet). Jain and Srinivasan (1990) retained the five CIP facets but operationalised each with exactly three items, yielding a 15-item instrument with a balanced 3x5 factorial structure. Their empirical assessment compared the NIP against PII, CIP, and PDI across multiple product categories. Particularly suited to studies requiring balanced factorial comparison of involvement facets, or when Sign Value is theoretically important.
