Measurement Characteristic and Assessment of Psychological Characteristics of Perfectionism and Optimism in Handball : Master's Thesis

Cilj ovog istraživanja bio je utvrditi metrijske karakteristike upitnika za procjenu psiholoških značajki perfekcionizma i optimizma u rukometu. Uzorak je sačinjavalo 48 vrhunskih rukometaša prosječne dobi 24 godine koji su bili podijeljeni prema pozicijama u igri na vratare, pivotmene, srednje vanjske i bočne vanjske igrače te krila. Izračunata je osnovna deskriptivna statistika i faktorska analiza te Cronbach alfa koeficijent na svim česticama psiholoških dimenzija perfekcionizma i optimizma. Sve čestice su pokazale zadovoljavajuće metrijske karakteristike. Također je izvršena analiza razlika u psihološkim značajkama prema igračkim pozicijama gdje nije prepoznata statistički značajna razlika. Može se zaključiti da je primjenjeni upitnik pouzdan i homogen te se može preporučiti kod korištenja na uzorku ispitanika vrhunskih rukometaša. Što se tiče razlika u dimenzijama psiholoških značajki koje smo promatrali u odnosu na poziciju u igri, one nisu pronađene. Jedan od razloga može biti manji broj ispitanika po subuzorku pa se eventualne razlike nisu na tom broju igrača ekstrahirale. U konačnici dobiveni rezultati ukazuju na visoku pouzdanost korištenih mjernih instrumenata kao i na veliki potencijal njihovog danjeg korištenja u znanstvenoj praksi.The aim of this study was to determine the metric characteristics of the questionnaire for assessing the psychological characteristics of perfectionism and optimism in handball. The sample consisted of 48 top handball players with an average age of 24 who were divided according to positions in the game into goalkeepers, line players, middle backs, side backs and wingers. Basic descriptive statistics and factor analysis and the Cronbach's alpha coefficient on all particles of the psychological dimensions of perfectionism and optimism were calculated. All particles showed satisfactory metric characteristics. Also, an analysis of differences in psychological characteristics according to player positions where no statistically significant difference was recognized, was performed. It can be concluded that the applied questionnaire is reliable and homogeneous and can be recommended for use on a sample of top handball players. About the differences in the dimensions of the psychological features we observed in relation to the position in the game, they were not found. One of the reasons may be the smaller number of respondents per subsample, so any differences were not extracted on that number of players. Ultimately, the obtained results indicate the high reliability of the used measuring instruments as well as the great potential of their further use in handball and scientific practice
