Abstract:
The reliability (internal consistency and alternate form) of the trait version of the Positive and Negative Mood Scales in referred samples was found to be high, and the concurrent and discriminate validity was found to be moderate. As expected, means of the Positive Mood Scales were significantly higher in nonreferred samples and means of the Negative Mood Scales were significantly higher in referred samples. The alternate forms for each scale were equivalent. The Positive and Negative Mood Scales seem to be ready for use in research.
