Measuring socio-cognitive factors in exercise participation: initial steps in developing and validating the Sp- AMSQEP
The impact of socio-cognitive factors in sport participation has become a popular topic in exercise and sport psychology. Although the components of self-efficacy, atitudes and motivation attract the attention of numerous studies yet there are no instruments measuring these three dimensions within the same instrument. This paper describes two studies conducted in order to develop and to obtain initial evidence regarding the fiability a validity of the Spanish Attitudes, Motivation and Self-efficacy Questionnaire of Exercise Participation (Sp- AMSQEP) – an instrument designed to measure the three constructs within the same questionnaire. Content as well as face validity helped us to refine the questionnaire by adding new items or by modifying others. During the phase 1, and through a pilot study a test/retest method was employed obtaining excellent indications of the repeatability of the research tool. In the preliminar application of phase 2 (N = 142) the internal consistency method was used obtaining satisfactory scores on the motivation and self -efficacy subscales, nevertheless the attitudes subscale presented some doubtful points. Finally an extented item analisis facilitated the detection of some points that by modifying them an increase in the internal consistency and the reliability of the instrument could be expected.
KEY WORDS: exercise participation, attitudes, motivation, self-efficacy.
