✦ Synopsis

The present studies examined the reliability and validity ojthe Preference Test ( P T ) , a widely used self-report index of preferred hemisphere thinking styles. The P T consists of items that intend to tap left-hemisphere and right-hemisphere cognitions. In the first study (N = 47), PT scores were .found to have reasonable test-retest stability. In the second study (N = 3341, afactor analysis of PT scores showed that the P T has a twofactor solution that can best be interpreted in terms qf putative left-and righthemisphere items. In the third study (N = 29), background EEG activity (F3, F4, P3 and P4) of subjects was recorded. P T scores were found to be related to EEG asymmetry patterns for frontal, but not for parietal, recording sites. More specifically, subjects with a left-hemisphere preference displayed relatively stronger left frontal activity than subjects with a right-hemisphere preference. By and large, the present findings provide strong support fbr the reliability and some suggestive evidence for the validity of the PT.

BACKGROUND: One important outcome in clinical trials is patients' own opinions about whether the medication alleviates their symptoms and improves their ability to function. A valid and reliable method with which to assess this subjective information is important. OBJECTIVE: To determine the validi
