Aspiration Index in Vocational Students–Dimensionality, Reliability, and Construct Validity

Abstract

The self-determination theory (SDT) distinguishes between intrinsic and extrinsic aspirations or life goals, which tend to fall into two separate constructs. The pursuit of intrinsic goals, relative to extrinsic ones, is associated with numerous cognitive, affective and behavioural outcomes that are considered to be positive for individuals as well as for society such as, for example, students’ school persistence. Developed by SDT researchers, the Aspiration Index has been widely explored. However, it has not previously been evaluated in Scandinavia. By means of confirmatory factor analysis and correlation analysis, the purpose of the current study was to examine the dimensionality, reliability, and construct validity of the Aspiration Index among health and social care students (N=415). The analysis revealed that a hypothesised second-order, two-factor model fits well with the observed data. The Aspiration Index also showed good reliability and construct validity in the present population of young people.
