Development of a 50-Item abridged form of the Junior Spanish version of the NEO questionnaire (JS NEO-A50)

The aim of this psychometric study was to construct an abridged 50-item form, 10 for each of the five factors of personality, of the Junior Spanish version of the NEO-PI-R (JS NEO-A50). Two separate studies were conducted. In Study 1, 400 high school students completed two personality scales to examine the factor structure (exploratory factor analysis), convergent validity, and reliability of the JS NEO-A50. In Study 2, an independent sample of 385 adolescents completed the JS NEO-A50 and several outcome measures to replicate the factor structure (exploratory structural equation model) and examine criterion validity, respectively. The five-factor structure found in Study 1 was satisfactorily replicated in the second, independent sample. Sources of reliability (internal consistency and test-retest) and validity (convergent) were adequate. Also, the outcome measures assessed in Study 2 were related to personality traits in the expected direction. Life satisfaction was significantly predicted by emotional stability; symptoms of behavioral problems were predicted by low scores in both agreeableness and conscientiousness while internalizing emotional symptoms were mainly predicted by emotional instability; finally, academic performance was mainly predicted by conscientiousness. We conclude that the JS NEO-A50 is a sound inventory to measure the five broad personality domains in Spanish-speaking adolescents
