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 grades 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 non-cognitive 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. [less ▲]

Workplace mobbing has various negative consequences for targeted individuals and are costly to organizations. At present it is debated whether gender, age, or occupation are potential risk factors. However, empirical data remain inconclusive as measures of workplace mobbing so far lack of measurement invariance (MI) testing – a prerequisite for meaningful manifest between-group comparisons. To close this research gap, the present study sought to further elucidate MI of the recently developed brief Luxembourg Workplace Mobbing Scale (LWMS; Steffgen, Sischka, Schmidt, Kohl, & Happ, 2016) across gender, age, and occupational groups and to test whether these factors represent important risk factors of workplace mobbing. Furthermore, we sought to expand data on criterion validity of the LWMS with different self-report criterion measures such as psychological health (e.g., work-related burnout, suicidal thoughts), physiological health problems, organizational behavior (i.e., subjective work performance, turnover intention, and absenteeism), and with a self-labeling mobbing index. Data were collected via computer-assisted telephone interviews (CATI) in a representative sample of 1,480 employees working in Luxembourg (aged from 16 to 66; 45.7% female). Confirmatory factor analyses revealed scalar MI across gender and occupation as well as partial scalar invariance across age groups. None of these factors impacted on the level of workplace mobbing. Correlation and receiver operating characteristic (ROC) analyses strongly support the criterion validity of the LWMS. Due to its briefness while at the same time being robust against language, age, gender, and occupational group factors and exhibiting meaningful criterion validity, the LWMS is particularly attractive for large-scale surveys as well as for single-case assessment and, thus, general percentile norms are reported in the Electronic Supplementary Materials.
