One of the earliest multidimensional conceptualisations of consumer involvement, the CP scale decomposes involvement into six theoretically distinct components. Lastovicka and Gardner (1979) drew on earlier work by Krugman (1965) and Rothschild (1979) to distinguish cognitive facets (importance, interest, risk probability), affective facets (pleasure), social-symbolic facets (sign value), and consequence-related facets (risk importance). The six-component model strongly influenced subsequent instrument development, most notably Laurent and Kapferer's (1985) CIP. Importance and Interest items most reliably differentiate high- from low-involvement product classes; Sign Value items differentiate publicly versus privately consumed products. Risk Importance and Risk Probability are theoretically orthogonal.
