Measuring academic motivation to achieve for high school students using a Rasch measurement model
… discarded) using the Extended Logistic Model of Rasch (Andrich, 1988a, 1988b; Rasch, 1980/1960) with the computer Program Rasch Unidimensional Measurement Models (RUMM-2010) (Andrich, Sheridan, Lyne & Luo, 2000). The iii structures, patterns and the psychometric properties of the scale were …

Analysis of the Scale of Parenting and Life Functioning Using the Rasch Measurement Model
… (SPLF). Analysis was conducted using a Rasch partial credit model. Overall, the SPLF showed good overall fit to the model. Unidimensionality of the scale was supported in the analysis, with over 60% of the raw variance explained by the measure. Item fit also provided evidence that the …
