How to Improve Athletes' Return of Investment: Shortening Questionnaires in the Applied Sport Psychology Setting

Abstract

In counseling settings we need short and understandable, as well as valid and reliable, questionnaires. However, test construction focuses primarily on the latter, resulting in rather long tests and athletes' perception of low return on time investment. We address this problem by explaining how questionnaires can be shortened (i.e., using three selection criteria) and validated (e.g., by calculating interitem correlations). As an example we shortened the Thought Occurrence Questionnaire Sport from 17 to three items. We argue why this short version still satisfies quality criteria and why such short(ened) questionnaires should be more appreciated (e.g., by publishing and using them in counseling settings).

Notes

1 We focus on how to shorten one-dimensional concepts including total scores. Multidimensional concepts bare specific challenges that we do not address in this research note.
