Development, Validity And Reliability of Physical Education Instructor’s Personality Description Scale
This current study describes the development, reliability and validation of a scale concerning the assessment of Physical Education Instructor’s Personality traits. According to the literature review, the Five Factor Model theory (Costa & McCrae, 1985; 1992; McCrae & Costa, 1987) is constituted by a widely accepted classification of human characteristics and an integrated description of human personality. For this reason, the questionnaire was structured based on the factors of Extraversion, Agreeableness, Conscientiousness, Emotional stability and lastly on the Openness to new experiences. The questionnaire was distributed to the owners of private health clubs and to the Managers of sports organization municipals who evaluated 481 Physical Education Instructors. During the exploratory factor analysis (n1=161) the criterion of Kaiser-Mayer-Olkin (.946) supported the total sufficiency and suitability of the sample for factor analysis, while the examination of Bartlett’s test of Sphericity (2642.791, df 171, p<.00001) led to the rejection of the null hypothesis that variables are independent. The Principal Components Analysis supported the existence of five (5) factors that interpret the 79.539% of overall variance. During the confirmatory factor analysis (n2=320), was checked the internal consistency with the Cronbach a index which gave: a=.87 for the extraversion, a=.90 for the agreeableness, a=.91 for the conscientiousness, a=.82 for the emotional stability/neuroticism and a=.92 for the openness to experience. The adaptation survey indicators [χ2 = 535.782, p<.001, Satorra-Bentler χ2 = 433.245, p<.001, df142, χ2 / df ratio = 3.051, NNFI = .902, CFI = .919, RCFI = .903, IFI = .920, SRMR = .052, RMSEA = .093 (90% CI of RMSEA =.085-.101)] supported the existence of five correlated factors and exceeded the questionnaire’s adaptability limits. Therefore, this specific questionnaire is a sufficient psychometric tool that can be used in the management of human resources in gyms and sports organizations
