Inventory Development
 Convergent Validity

 

Convergent validity was demonstrated in several ways. First, teachers' TSI scores were correlated with ratings made independently by a significant other, a person who knew the teacher well. Second, total TSI scores were correlated with the presence of certain personal and professional characteristics, all of which were hypothesized to correlate very little with the TSI scores. And third, TSI scores were correlated with measures of various psychological, physiological, and organizational constructs that had been hypothesized to be related to stress. Collectively, the three sets of correlations provide evidence for the validity of the TSI.
