PERCEIVED USEFULNESS, PERCEIVED EASE OF USE, AND USER ACCEPTANCE OF INFORMATION TECHNOLOGY: AN ARTICLE CRITIQUE

The article "Perceived usefulness, perceived ease of use, and user acceptance of information technology" is critiqued in this research. The critique covers validity, variance, procedures, factor analysis, internal consistency, moderator variable, multiple regression, and reliability.

Validity is critiqued in five contexts. These contexts are face, content, predictive or criterion, construct, and concurrent.

Face validity is that quality of an indicator that makes the indicator at least appear to be a reasonable measure of some variable. The principle explanatory variables involved in the research reported in the critiqued article were user perceived usefulness of information technology and user perceived ease of use of information technology. Potential indicators of these variables were identified through the literature. This procedure provided face validity in the search for indicator measures of the two explanatory variables.

Content validity is the degree to which a measure covers the range of meanings included in the concept of some variable. A pre-test and pre-test interviews were used in the research reported in the critiqued article to assess the content validity of the selected indicator measures.

Criterion validity is the degree to which a measure of some variable relates with some external criterion. Criterion validity was not addressed directly in the critiqued article.

Construct validity is the degree to which a measure relates to other variables as expected within a system of theoretical relationships. A field study was used in the research reported in the critiqued article to assess the construct validity of the measurement scales developed.

Concurrent validity refers to the extent to which items comprising a scale behave as if they are measuring the same variable. Correlation analy...
