A systematic procedure for constructing a valid microcomputer attitude scale

Abstract The purpose of this study was twofold: (1) to design a system for constructing Likert attitude scales as supported by the sociopsychological and measurement literature, and (2) using the design to assemble a microcomputer attitude scale for inservice and preservice teachers ( n = 281). The results of the study: (1) a 15‐step flow chart for designing reliable and valid attitude scales, and (2) a 23‐item microcomputer Likert attitude scale with the following characteristics: (a) coefficient alpha 0.89, (b) range of adjusted item‐total correlations from 0.29 to 0.62, (c) range of interitem correlations from 0.04 to 0.60, (d) correlation of 0.20 with a mathematics attitude scale and 0.02 with a reading attitude scale, and (e) favorable factor analysis and emotional intensity data.
