Interna metrijska svojstva skala Gilford-Zimermanovog pregleda temperamenta

Abstract

Na uzorku od 480 studentkinja i 480 studenata proveravane su interne metrijske karakteristike Gilford-Zimermanovog pregleda temperamenta. Pouzdanosti skala iskazane Kronbahovim alfa-koeficijentom kreću se u rasponu od 0.69 do 0.86. Koeficijenti pouzdanosti određeni (pod Gutmanovim modelom merenja) Gutman-Najsvonderovim postupkom kretali su se od 0.74 (skala 'Sklonosti dobrim međuljudskim odnosima') do 0.90 (skala 'Društvenosti'). Mada nedovoljno visoki, ovi koeficijenti spadaju u izraženije u odnosu na one drugih inventara ličnosti. Reprezentativnost skala određena Kajzer-Rajsovim postupkom kretala se od 0.78 ('Sklonost dobrim međuljudskim odnosima') do prihvatljivih 0.95 ( 'Društvenost'). Procene homogenosti - dobijene na osnovu Momirovićevog postupka za 'imidž homogenost' su u rasponu od 0.45 (skala 'Uzdržanosti') do 0.69 (skala 'Refleksivnosti'). Sa stanovišta valjanosti to znači da je gotovo polovina varijanse pravih rezultata na većini skala posledica uticaja drugačijih od onih čijem su merenju skale namenjene. Skala 'Društvenosti' svojim metrijskim karakteristikama u najvećoj meri zadovoljava psihometrijske standarde.

Internal metric characteristics of 'Guilford-Zimmerman Temperament Survey' were checked on the sample of 480 female students and 480 male students. Reliability of the scales shown by Cronbach Alfa-coefficient is within the range of 0.69 to 0.86. Reliability coefficients calculated by Guttman-Nicewander method (under Guttman's measurement model) are within the range of 0.74 ('Personal relations' scale) to 0.90 ('Sociability' scale). Though insufficiently high, these coefficients are prominent in relation to the coefficients for the other personality inventories. Representativity scores for the scales measured by Kaiser- Rice method are within the range of 0.78 ('Personal Relations' scale) to the acceptable 0.98 ('Sociability' scale). Homogeneity scores calculated by Momirović method for 'homogeneity image' are within the range of 0.45 ('Thoughtfulness' scale) to 0.69 ('Restraint' scale). From the validity viewpoint that means that nearly half of real scores' variance for the majority of scales is result of the influences different from those for which the scales are purported. By its metric characteristics 'Sociability' scale fulfills the psychometric standards to the greatest extent.
