Psychometric evaluation of measures of organizational commitment and intention to quit among pharmaceutical scientists.

This study utilized different statistical techniques to evaluate the reliability (internal consistency) and the discriminant validity of the most widely used measures of organizational commitment and intention to quit (the employing organization). Data were obtained from a national mail survey of members of the American Association of Pharmaceutical Scientists (AAPS) working in the pharmaceutical industry. Both instruments had high Cronbach alpha values in this sample of pharmaceutical scientists. There was a substantial correlation between the scale designed to measure organizational commitment and that for intention to quit. Factor analysis revealed that there was only one common factor underlying the 20 items that were originally designed to measure two distinct constructs. The findings in this study suggested that the most widely used instruments designed to measure organizational commitment and intention to quit may be actually measuring one construct, or the theoretical constructs named as organizational commitment and intention to quit may not be empirically distinct.
