A Need for Cognition Scale for Children and Adolescents Structural Analysis and Measurement Invariance

Need for Cognition (NFC) signifies "the tendency for an individual to engage in and enjoy thinking" (Cacioppo & Petty, 1982, p. 116). Up to now, no scale of sufficient psychometric quality existed to assess NFC in children. Using data from three independent, diverse cross-sectional samples from Germany, Luxembourg, and Finland, we examined the psychometric properties of a new NFC scale intended to fill in this gap. In all samples, across grade levels ranging from 1 to 9, confirmatory factor analysis confirmed the hypothesized nested factor structure based on Mussel's (2013) Intellect model, with one general factor Think influencing all items and two specific factors Seek and Conquer each influencing a subset of items. At least partial scalar measurement invariance with regard to grade level and sex could be demonstrated. The scale exhibited good psychometric properties and showed convergent and discriminant validity with an established NFC scale and other noncognitive traits such as academic self-concept and interests. It incrementally predicted mostly statistically significant but relatively small portions of academic achievement variance over and above academic self-concept and interest. Implications for research on the development of NFC and its role as an investment trait in intellectual development are discussed.
