Reliability and Validity of The Attentional and Interpersonal Style (TAIS) Inventory Concentration Scales

In 1976 I published a book titled, The Inner Athlete dealing with Sport Psychology (Nideffer, 1976a), and an article in the Journal of Personality and Social Psychology (Nideffer, 1976b) on the development of a psychological test called The Attentional and Interpersonal Style (TAIS) Inventory. The Inner Athlete dealt with the role concentration plays in performance and presented a set of theoretical constructs that began to behaviorally define what it means to concentrate. TAIS was a 144 item, self-report, paper and pencil inventory, that had been developed to measure the behaviorally defined concentration styles, and interpersonal characteristics that the theory of attentional and interpersonal style hypothesized were the building blocks of performance.
