The measure of intrinsic and extrinsic motivation in tennis

A questionnaire was designed to estimate the quality and intensity of motivation of tennis players (Kumburić, 2015), based on the model of Deci and Ryan (1985). The designed questionnaire consists of 38 items that form six subscales, including six regulatory styles described by Deci and Ryan (1985). The analysis of the measurement properties of questionnaire was done on the sample of 174 junior tennis players aged from 15 to 18 years. The analysis show that the newly designed questionnaire has overall Cronbach alpha reliability of α=0.849, which implies that the questionnaire is applicable for practical purposes. The analysis of the measurement properties of subscales showed Cronbach alpha reliability α=0.74 for intrinsic motivation subscale, α=0.563 for identified motivation subscale, α=0.657 for integrated motivation, α=0.61 for introjected motivation, α=0.628 for external motivation, and α=0.582 for amotivation subscale. The reliability of the subscales is not adequate for the individual application (e.g. to estimate the profile of a player).
