CREATION OF THE NEW PSYCHOMETRIC INSTRUMENT FOR EDUCATION OF THE DENTOFACIAL AESTHETICS

Cilj istraživanja bio je kreirati i validirati nove instrumente za procjenu psihosocijalnih dimenzija koje bi mogle biti vezane uz percepciju dentofacijalne estetike. Tim od pet stručnjaka izabrao je 101 česticu koja bi mogla činiti specifične hipotetske dimenzije. Za dimenzije samopercepcija tjelesnog izgleda, zadovoljstvo dentofacijalnom estetikom, dentalno samopouzdanje, zabrinutost dentofacijalnom estetikom, percepcija dentofacijalne estetike i socijalni utjecaj dentofacijalne estetike pretpostavilo se da su pod utjecajem dentalnih intervencija. Za perfekcionizam, samopoštovanje i slika tijela pretpostavilo se da su relativno stabilne i u vrlo maloj mjeri podložne utjecaju dentalnih intervencija. Istraživanje je provedeno na uzorku od 261 ispitanika, učenika i studenata škola i Sveučilišta u Rijeci (26,4% muških), raspona godina od 14 do 28, koji su ispunili kreirani upitnik. Za statističku analizu korištene su faktorska analiza, Cronbachova α te Pearsonova korelacija i regresijska analiza. Potvrđena je očekivana faktorska struktura svake od hipotetskih dimenzija kroz ukupno 46 čestica. Unutarnja konzistencija bila je zadovoljavajuća (α u rasponu 0.66-0.90; prosječne interkorelacije čestica u rasponu 0.29-0.66). Novi mjerni instrumenti značajno koreliraju s postojećim koji mjere slične konstrukte (r=0.27-0.76). Novi mjerni instrumenti su kratki i dobri pokazatelji psihosocijalnih dimenzija vezanih uz percepciju dentofacijalne estetike. Mogli imati praktičnu valjanost prilikom korištenja u dentalnim kliničkim postupcima.The purpose of this research was to create and validate new instruments of evaluating psychosocial dimensions that might be related to perception of orofacial aesthetics. A team of five experts chose 101 particle that could draw up specific hypothetical dimensions. Assumption to be influenced by dental interventions has been made for dimensions self-perception of body image, satisfaction with orofacial aesthetics, dental self-confidence, concern for orofacial aesthetics, perception of orofacial aesthetics, and social impact of orofacial aesthetics whereas the following dimensions – perfectionism, self-respect, and body image – were assumed to be relatively stable when it comes to being subject to the influence of dental interventions. The research was conducted on 261 examinees, pupils and students of secondary schools and University of Rijeka (26,4% male) in the 14–28 age range, that have completed the designed questionnaire. Factor analysis, Cronbach’s alpha, Pearson correlation and regression analysis were used for statistical analysis. The expected factorial structure of each hypothetical dimension was confirmed through 46 particles. Inner consistency was satisfactory (α in 0,66–0,90 range; average intercorrelation of particles in the range of 0,29–0,66). New measurement instruments correlate significantly with the existing ones that measure similar constructs (r= 0,27–0,76). New measurement instruments are short and have proven to be good indicators of psychosocial dimensions related to perception of orofacial aesthetics. They might have practical validity when applied in dental clinical procedures
