CONVERGENT VALIDITY AND RELIABILITY FOR A MEASURE OF PERCEPTION OF CONTROL FOR THOSE WITH DIABETES

Objectives. This study assesses the reliability and factor structure o f six positive and six negative dimensions of perceived control with p eople with insulin-dependent diabetes. Design. The dimensional structu re of these six positive and six negative constructs was assessed in t erms of six one-factor models, where positive and negative factors wer e combined. This solution was compared with one where a separate facto r structure was proposed for each of the positive and negative dimensi ons. Methods. The reported results were based upon a series of confirm atory 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 ra nged from .59 to .74. Conclusions. These results provide evidence for the internal validity and reliability of this particular measure of pe rceived control among individuals with insulin-dependent diabetes.
