The key study goals were as follows: (a) to examine the validity evidence based on the internal structure drawn from the scores on the SAI-SV using principal axis factoring (PAFs); (b) to examine the assumptions of univariate and multivariate normality or distribution of the SAI-SV items; (c) to examine the validity evidence based on the internal structure drawn from the scores on the SAI-SV using CFAs; (d) to estimate the internal consistency (Cronbach's alpha coefficients) of scores on the SAI-SV; and (e) to estimate 2-week test-retest reliability coefficients for SAI-SV scores.
