摘要：Background: The importance of valid and reliable instruments for the assessment of
factors affecting students’ interest in science encouraged the development and
validation of a brief Spanish instrument for the measurement of expectancies of
success in school science, named SUCCESS. In this study, the psychometric properties
of the SUCCESS instrument are further evaluated using different psychometric tests
and a different sample than the one included in the original validation study.
Material and methods: A sample of 313 Spanish elementary school students enrolled
in 4th to 6th grade was drawn by means of convenience sampling techniques. Responses
were analyzed in terms of construct and criterion validity, and two reliability indices.
Results: Results from confirmatory factor analysis established the unidimensional
structure of the instrument, with great model fit indices. Correlation coefficients
between the SUCCESS and external measures (i.e. intentions to enroll, enjoyableness,
difficulty, auto-efficacy, utility and relevance of school science) provided evidence of
criterion validity. Cronbach α and item-total correlation indices supported the internal
consistency reliability of the instrument.
Conclusions: Taken together, this study further provide evidence to consider the
SUCCESS as a valid and reliable tool for the measurement of Spanish elementary school
students expectancies of success in school science.
