Convergent Validity of the PUTS

Convergent Validity of the PUTS

Premonitory urges are a cardinal feature in Gilles de la Tourette syndrome. Severity of premonitory urges can be assessed with the "Premonitory Urge for Tic Disorders Scale" (PUTS). However, convergent validity of the measure has been difficult to assess due to the lack of other urge measures. We investigated the relationship between average real-time urge intensity assessed by an in-house deve...

Convergent and Discriminant Validity

Convergent and Discriminant Validity

Example: Convergent/discriminant Validity

Sociologist James A. Quinn states that the tasks of scientific method are related directly or indirectly to the study of similarities of various kinds of objects or events. One of the tasks of scientific method is that of classifying objects or events into categories and of describing the similar characteristics of members of each type. A second task is that of comparing variations in two or mo...

Evidence of Convergent Validity on the Dimensions of Affect

Despite widely differing methodologies, previous studies on affect (emotion as represented in language) have often obtained what appear to be the same basic dimensions. Whether these similarly named dimensions from different methodologies are actually equivalent was tested here by intercorrelating dimensions obtained from multidimensional scaling, successive-intervals scaling, semantic differen...
