Abstract

Objectives. This study assesses the reliability and factor structure of six positive and six negative dimensions of perceived control with people with insulin-dependent diabetes. Design. The dimensional structure of these six positive and six negative constructs was assessed in terms of six one-factor models, where positive and negative factors were combined. This solution was compared with one where a separate factor structure was proposed for each of the positive and negative dimensions. Methods. The reported results were based upon a series of confirmatory factor models using weighted least squares. Results, Maintaining a separate factor structure for the positive and negative dimensions was the preferred solution. The reliabilities from these 12 factors ranged from .59 to .74. Conclusions. These results provide evidence for the internal validity and reliability of this particular measure of perceived control among individuals with insulin-dependent diabetes.
