Abstract

Pendahuluan. Kualitas hidup terkait kesehatan selama pasien menderita HIV menjadi perhatian yang menarik dan dapat digunakan sebagai salah satu indikator keberhasilan terapi yang telah diberikan. Salah satu instrumen untuk menilai kualitas hidup pasien adalah kuesioner WHOQOL-HIV BREF yang telah digunakan di berbagai negara, namun belum pernah diuji kesahihan dan keandalannya di Indonesia. Penelitian ini bertujuan untuk menguji kesahihan dan keandalan kuesioner WHOQOL-HIV BREF dalam bahasa Indonesia sebagai alat untuk mengukur kualitas hidup pada pasien HIV/AIDS.

Metode. Penelitian potong lintang dilakukan di Poliklinik khusus HIV Rumah Sakit dr. Cipto Mangunkusumo (POKDISUS RSCM), Jakarta pada bulan November 2016 dengan cara consecutive sampling. Penelitian dilakukan dalam dua tahap yaitu tahap awal yang merupakan proses adaptasi bahasa dan budaya dan tahap akhir yaitu uji kesahihan dan keandalan dari kuesioner.

Hasil. Sebanyak 56 responden ikut serta dalam penelitian ini dan diketahui bahwa 69,6% di antaranya adalah laki-laki. Melalui pendekatan multi-trait scaling analysis, didapatkan nilai koefisien korelasi yang tinggi terhadap skor total domainnya,sehingga dapat dikatakan kuesioner tersebut memiliki validasi yang baik. Uji korelasi antardomain kuesioner WHOQOL-HIV BREF dan domain kuesioner SF-36 menunjukkan bahwa terdapat enam domain yang signifikan bermakna (p <0,005) dengan nilai koefisien korelasi kuat (r= 0,60 – 0,79). Keandalan kuesioner dinilai dengan intra class correlation coefficient masing-masing domain 0,401-0,484 dan nilai Alpha Cronbach 0,513-0,798.

Simpulan. Kuesioner WHOQOL-HIV BREF dalam bahasa Indonesia sahih dan andal.

Through a multi-trait scaling analysis, it was found that correlation coefficient value had a high correlation to the total score domain, which meant that it had a good validation. Correlation between questionnaire domain WHOQOL-HIV BREF and SF-36 questionnaire domain obtained 6 significant domains (p <0.005) with a strong correlation coefficient (r = 0.60 to 0.79). Reliability of the questionnaire was assessed by intra class correlation coefficient, each domain from 0.401 to 0.484 and 0.513 to 0.798 for Cronbach Alpha.
