Uji Kesahihan dan Keandalan Edinburgh Handedness Inventory (EHI) Versi Bahasa Indonesia yang Diadaptasi Terhadap Dominansi Tangan = Validity and Reliability Test of Indonesian Version of Edinburgh Handedness Inventory (EHI) as A Hand Dominance Measurement.

Objektif: Penelitian ini bertujuan untuk menilai kesahihan dan keandalan Edinburgh Handedness Inventory (EHI) versi bahasa Indonesia sebagai alat ukur dominansi tangan pada dewasa muda sehat. Metode: Penelitian ini menggunakan desain studi potong lintang dengan pengambilan sampel secara acak sederhana. Penelitian terdiri dari tahap adaptasi transkultural dengan metode WHO menggunakan forward-backward translation, dilanjutkan tahap uji kesahihan dan keandalan. Penelitian dilakukan di Klinik Tangan Rehabilitasi Medik RSUPN dr. Cipto Mangunkusumo. Hasil: Jumlah subjek penelitian 40 orang (31 wanita dan 9 pria) dengan median usia 27,63 ± 5,1. Mayoritas subjek penelitian memiliki tingkat pendidikan tamat sarjana/sederajat sebesar 52,5%, dengan sisanya tamat pendidikan SMA/sederajat sebesar 45% dan tamat pendidikan SMP/sederajat sebesar 2,5%. Didapatkan EHI versi Bahasa Indonesia merupakan instrumen yang sahih (nilai kesahihan konstruk r= 0,37-0,66) dan andal (nilai konsistensi internal alfa Cronbach 0,79-0,82) sebagai alat ukur dominansi tangan pada dewasa muda sehat. Hasil dominansi tangan terbagi menjadi tiga kelompok dengan kinan/dominan kanan sebesar 80%, kikan/dominan kedua tangan sebesar 17,5% dan kidal/dominan kiri sebesar 2,5%. Waktu pengisian kuesioner memiliki rerata 7.5 ± 1.09 menit. Kesimpulan: EHI versi Bahasa Indonesia merupakan instrumen yang sahih dan andal sebagai alat ukur dominansi tangan pada individu sehat.

Objective: This study aimed to assess the validity and reliability of Indonesian Version of Edinburgh Handedness Inventory (EHI) as a hand dominance measurement Methods: This study is a cross-sectional study with simple random sampling. The study consisted of transcultural adaptation with the WHO method using forwardbackward translation stage and a validity and reliability testing stage. Healthy young volunteers were enrolled in the study. The study was conducted at Hand Rehabilitation Clinic of dr. Cipto Mangunkusumo National General Hospital. Results: A total of 40 participants (31 women and 9 men) with a median age of 27.63 ± 5.1 years were enrolled in this study. Most participants had a universitylevel education (52.5%), while 45% had completed high school, and 2.5% had completed junior high school. Hand dominance was categorized into three groups: 32 participants reported as right dominant (80%), seven participants (17.5%) as ambidextrous and only one (2.5%) participant reported as left dominant. The Indonesian version of EHI demonstrated good construct validity (correlation coefficient r = 0.37-0.66) and internal consistency reliability (Cronbach’s alpha = 0.79-0.82) as an instrument for measuring hand dominance in healthy young adults. The average questionnaire completition time was 7.5 ± 1.09 minutes. Conclusion: Indonesian version of EHI is a valid and reliable instrument for measuring hand dominance in healthy individual.
