A modified work locus of control scale: preliminary investigation of reliability and validity in a sample of pharmacists.

Items in Spector's Work Locus of Control-Scale were modified to reflect how much control the respondent feels he might have on a job as opposed to what he feels people in general have. This modified Work Locus of Control Scale was tested for reliability and construct validity. As part of a larger study, data were collected via mail questionnaires from a sample of 284 pharmacists licensed in Indiana. The Cronbach coefficient alpha for the modified scale was .88, indicating good internal consistency. The modified scale also showed some evidence of convergent validity when correlated with scores on measures of Extraversion, Conscientiousness, Neuroticism, and Job Dissatisfaction.
