Tujuan: Reliabilitas dan validitas kuesioner COHIP-SF 19 versi Bahasa Indonesia. Metode: Dibuat berdasarkan pedoman proses adaptasi cross-cultural. Penelitian dilakukan pada 548 anak usia 12 - 15 tahun dari enam SMP Negeri di Jakarta yang dipilih secara acak. Tes psikometrik mencakup konsistensi internal, reliabilitas test-retest, validitas diskriminan, dan validitas konvergen. Hasil: Mean usia subjek penelitian adalah 13,3 tahun (SD 0,9) dan 54% subjek penelitian merupakan perempuan. Mean COHIP-SF 19 adalah 57,8 (SD 8,8) dan mediannya adalah 58 (rentang 27 - 75). Konsistensi internal dan reliabilitas test-retest COHIP-SF 19 sangat baik dengan nilai Chronbach’s alpha 0,83 dan intra-class correlation coefficient (ICC) 0,81. Anak-anak dengan decay aktif, PUFA positif, rongga mulut tidak bersih, atau gingivitis memiliki skor COHIP-SF 19 yang lebih rendah secara signifikan (P ≤ 0,030). Korelasi antara skor COHIP-SF 19 dan masing-masing domain, dengan tingkat keparahan klinis dan penilaian diri terhadap kesehatan umum atau kesehatan rongga mulut setelah disesuaikan dengan usia, jenis kelamin, dan sekolah sangat rendah hingga rendah (│rs│ = 0,04 – 0,27, P ≤ 0,028). Kesimpulan: COHIP-SF 19 versi Bahasa Indonesia berhasil dibuat untuk digunakan sebagai instrumen OHRQoL pada anak-anak usia sekolah di Indonesia. Konsistensi internal, reliabilitas test-retest, validitas diskriminan, dan validitas konvergen COHIP-SF 19 versi Bahasa Indonesia sudah dibuktikan.

Objectives: Assessing reliability and validity of COHIP-SF 19 Indonesian version.

Methods: Developed according to the guidelines for the cross-cultural adaptation process. The instrument was tested among 548 children age 12 – 15 years old, from randomly selected six junior high school in Jakarta. The psychometric test include internal consistency, test-retest reliability, discriminant validity, and convergent validity.

Results: Mean age of the participants was 13,3 years (SD 0,9) and 54% of the participants were girls. The mean score was 57,8 (SD 8,8) and the median was 58 (range 27-75). The internal consistency and test-retest reliability was excellent with Chronbach’s alpha 0,83 and intra-class correlation coefficient (ICC) 0,81. Children with active decay, positive PUFA, not clean oral cavity, or gingivitis had significantly lower scores (P ≤ 0,030). Correlation between COHIP-SF 19 score, subscale scores and clinical severity as well as self-rated general or oral health were very low to low (│rs│ = 0,04 - 0,27, P ≤ 0,028), after adjustment for children’s age, gender, and school.

Conclusion: The Indonesian version of COHIP-SF 19 was successfully developed to be used as an OHRQoL instrument for Indonesian school-age children. The internal consistency, test-retest reliability, discriminant validity, and convergent validity of COHIP-SF 19 Indonesian version were confirmed.
