Purpose: The ability to perform motor imagery has been shown to influence individual athletic performance and rehabilitation. Recent evidence supports its potential as a training tool to improve motor skills in children. Although there is a standardized assessment of the imagery abilities in Slovenian-speaking adults, there is currently no validated instrument for use with Slovenian children. Therefore, the aim of the present study was to conduct a linguistic validation study of the movement imagery questionnaire for children (MIQ-C).
Methods: A total of 100 healthy children (mean age 10.3±1.3 years; 50 female) were assessed with a Slovenian version of the MIQ-C at Day 1 and Day 8. Inter-day agreement was examined using intraclass correlation coefficients (ICC). Construct validity and internal consistency were assessed using a Cronbach's alpha coefficient and exploratory - confirmatory factor analysis, respectively.
Results: The test-retest ICC were very high for all three scales examined (ICCKI=0.90; ICCIVI=0.92; ICCEVI=0.90). Excellent internal consistency (up to 0.90) was found for kinaesthetic and both visual imageries. Confirmatory analysis confirmed a three-factorial structure of the MIQ-C.
Conclusions: The Slovenian version of the MIQ-C proved to be highly reliable and valid in assessing children's motor imagery abilities, and as such for use with Slovene-speaking children. Moreover, this standardized instrument can be a helpful tool in training and rehabilitation practice with children aged 7-12 years.
Namen: Dokazano je, da sposobnost izvajanja gibalnih predstav vpliva na posameznikovo športno zmogljivost in rehabilitacijo. Najnovejši dokazi potrjujejo, da lahko služi kot vadbeno orodje za izboljšanje gibalnih sposobnosti otrok. Čeprav obstaja standardizirano ocenjevanje zmožnosti gibalnih predstav odraslih, ki govorijo slovensko, trenutno ni potrjenega instrumenta za uporabo pri slovenskih otrocih. Zato je bil namen pričujoče študije izvesti jezikovno validacijsko študijo vprašalnika o gibalnih predstavah za otroke (MIQ-C).
Metode: Vzorec je predstavljalo 100 zdravih otrok (povprečna starost 10,3 ± 1,3 leta; 50 žensk), ki so bili ocenjeni s slovensko različico vprašalnika MIQ-C prvega in osmega dn. Ujemanje med dnevi je bilo preverjeno s koeficienti znotrajrazredne korelacije (ICC). Veljavnost konstrukcije in notranja skladnost sta bili ocenjeni z uporabo Cronbachovega testa alfa oziroma raziskovalno-potrditvene faktorske analize.
Rezultati: Rezultati ICC za vse tri pregledane lestvice so bili zelo visoki (ICCKI = 0,90; ICCIVI = 0,92; ICCEVI = 0,90). Odlična notranja konsistentnost (do 0,90) je bila ugotovljena pri kinestetičnih in obeh vizualnih predstavah. Potrditvena analiza je potrdila trifaktorsko strukturo MIQ-C.
Zaključki: Slovenska različica vprašalnika MIQ-C se je izkazala kot zelo zanesljiv in veljaven inštrument za oceno gibalne predstave in se kot tak uporablja pri slovensko govorečih otrocih. Poleg tega je ta standardizirani inštrument lahko koristno orodje v vadbeni in rehabilitacijski praksi z otroki, starimi od 7 do 12 let.
