Automobile involvement: IPCA (Bloch 1981)


The concept ‘product involvement is perceived as a long term interest in a product based on the product’s core centrality to needs, self-concept and values. However, it was Bloch (1981) who conceptualized the use of product involvement as a construct that would ultimately affect the behaviour of consumers which varies from individual to individual. In this regard, a measurement scale was proposed which is used to measure the involvement of consumers towards automobiles. The scale consists of six factors and uses a 17 point Likert scale. Following are the factors

  • Driving enjoyment and usage of automobiles
  • Consumers’ readiness to talk about cars
  • Consumers’ attachment towards cars
  • Consumers’ interests towards racing
  • self-expression through one’s car
  • Consumer’s interest in cars
