Thesis (Ph.D.)--James Madison University, 2007.

Using the framework of a strong program of construct validation (Benson, 1998), the current study investigated Self-Determination Theory (SDT; Deci & Ryan, 1985), the construct of academic motivation, and the Academic Motivation Scale (AMS; Vallerand et al., 1992). Building upon a body of prior research that provided only limited support for the theory and the seven-factor structure of the scale, a technique other than factor analysis was used to analyze responses to the AMS. Specifically, the utility of a unidimensional unfolding model in analyzing such responses was explored. In addition, scale development efforts were pursued, and multiple measures of academic motivation within a single sample of students were compared.Subjects--Topical Terms:

520 $a Using the framework of a strong program of construct validation (Benson, 1998), the current study investigated Self-Determination Theory (SDT; Deci & Ryan, 1985), the construct of academic motivation, and the Academic Motivation Scale (AMS; Vallerand et al., 1992). Building upon a body of prior research that provided only limited support for the theory and the seven-factor structure of the scale, a technique other than factor analysis was used to analyze responses to the AMS. Specifically, the utility of a unidimensional unfolding model in analyzing such responses was explored. In addition, scale development efforts were pursued, and multiple measures of academic motivation within a single sample of students were compared.
520 $a Data were collected from three large samples of university students over the period of one year. The AMS and other instruments were self-report measures administered on computer and by paper-and-pencil. Qualitative data were collected from the second sample for the purposes of exploring new content for pilot items and for explaining certain results.
520 $a Results have important implications for both SDT and the measurement of academic motivation using the AMS. A unidimensional unfolding model was shown to provide adequate fit to the data, supporting the argument that academic motivation is a single construct ordered along a continuum according to increasingly internal degrees of self-regulation. Using the estimated item locations, a shortened version of the AMS was proposed that was highly reliable and consistent with SDT. Finally, a comparison of unfolded motivation scores with summated AMS subscale scores revealed the "folding" of the response process.
