| Abstract | Cilj istraživanja: Prevesti s engleskog jezika na hrvatski jezik instrument Malocclusion
Impact Questionnaire (MIQ) i analizirati njegovu strukturu.
Nacrt studije: Presječna studija
Ispitanici i metode: Naprijed-natrag prijevod učinila su četiri neovisna prevoditelja s dobrim
znanjem obaju jezika. Panel od pet stručnjaka pratio je proces i usuglasio hrvatsku inačicu
prijevoda. Uzorak je činilo 254 ispitanika dobi između 10 i 18 godina (medijan 15 godina),
52 % djevojčica. Kliničkim pregledom određen im je stupanj malokluzije Indeksom potrebe
za ortodontskom terapijom i Littleovim indeksom nepravilnosti inciziva. Izvijestili su
zadovoljstvo izgledom i potrebu za terapijom Likertovom ljestvicom (0 = uopće ne – 4 = jako
puno) te utjecaj malokluzije instrumentima MIQ-a, Psihosocijalnim utjecajem dentalne
estetike i Ljestvicom ograničenja funkcije čeljusti.
Rezultati: Faktorska analiza pokazala je da jednodimenzionalni MIQ objašnjava 46 %
varijance i ima visoku unutarnju konzistentnost (Cronbach α = 0,920). Čestica gristi hranu
najmanje korelira s ostalim česticama i njezino bi izbacivanje poboljšalo konzistentnost
jednodimenzionalnog instrumenta (α = 0,927). MIQ značajnije linearno korelira sa
zadovoljstvom izgleda zubi i lica (r = 0,575 i 0,411; p < 0,001) nego samoreportiranom
potrebom za terapijom zubi i lica (r = 0,421 i 0,366; p < 0,001). Utjecaj malokluzije
proporcionalan je pacijentovoj perspektivi estetske komponente intenziteta malokluzije
(r = 0,321; p < 0,001), ali nije potrebi za ortodontskom terapijom zbog dentalnog zdravlja.
MIQ je najbolje korelirao s psihološkim i socijalnim utjecajima dentalne estetike (r = 0,762 i
0,740; p < 0,001), a nije korelirao s ograničenjima žvakanja.
Zaključak: Jednodimenzionalni MIQ ima zadovoljavajuća psihometrijska svojstva i dobra je
mjera psiholoških i socijalnih utjecaja narušene dentalne estetike, ali ne i oralne funkcije. |
| Abstract (english) | Research aim: Translate the Malocclusion Impact Questionnaire (MIQ) from English into
Croatian, adapt it and analyze the structure of the impact of malocclusion on adolescents.
Study design: Cross-sectional study
Materials and Methods: The forward-backward translation was made by four independent
translators with good knowledge of both languages. A panel of five experts supervised the
process and harmonized the Croatian version of the translation. The sample consisted of 254
individuals aged 10 to 18 years (median 15 years), of whom 52 % were female. The severity
of dental malocclusion was determined by clinical examination using the Index of
Orthodontic Treatment Need – Dental Health Component and Little's Irregularity Index. The
subjects' satisfaction and treatment needs were assessed using a Likert scale (0 = not at all –
4 = very much), and the effects of malocclusion were assessed using the MIQ instrument, the
Psychosocial Impact of Dental Aesthetics Questionnaire, and the Jaw Function Limitation
Scale.
Results: Factor analysis revealed that a unidimensional MIQ explained 46 % of the variance
and had high internal consistency (Cronbach α = 0,920). The item biting food, correlated least
with the other items, and if it were deleted, the consistency of the unidimensional structure
would improve (α = 0,927). The MIQ correlated linearly more strongly with satisfaction with
teeth and smile appearance (r = 0,575 and 0,411; p < 0,001) than with self-reported need for
therapy (r = 0,421 and 0,366; p < 0,001). The impact of malocclusion was proportional to the
severity of malocclusion (r = 0,321; p < 0,001), but not to the need for orthodontic treatment
based on dental health. The MIQ correlated most strongly with the psychological and
sociological effects of dental esthetics (r = 0,762 and 0,740; p < 0,001) and was not correlated
with chewing limitations bite.
Conclusion: The unidimensional MIQ has satisfactory psychometric properties and is a good
measure of the psychological and social impact of impaired dental esthetics, but not of oral
function. |
