Prevalensi hipertensi di Yogyakarta semakin meningkat, maka diperlukan suatu alat untuk mengukur kualitas hidup pasien hipertensi sebagai salah satu luaran terapi hipertensi. Telah dilakukan validasi instrumen SF-36 pada pasien hipertensi di puskesmas di Yogyakarta. Penelitian ini dilakukan bertujuan untuk mengetahui hasil validasi instrumen tersebut yang telah dirubah susunan pertanyaannya berdasarkan validasi sebelumnya. Penelitian ini menggunakan rancangan cross sectional yang dilakukan secara prospektif. Data diambil melalui wawancara pada pasien hipertensi. Subjek penelitian adalah pasien hipertensi yang menjalani rawat jalan di puskesmas di Yogyakarta periode Februari - Maret 2013. Kuesioner tersebut dianalisis dengan uji reliabilitas dan uji validitas yang menggunakan validitas diskriminan, konvergen dan uji Known Group Validity untuk membedakan kualitas hidup kelompok pasien tertentu. Subyek dalam penelitian berjumlah 30 pasien hipertensi. Kuesioner ini dinyatakan reliabel karena nilai cronbach alpha ≥ 0,70. Hasil validitas konvergen menunjukkan bahwa nilai pada domain yang diujikan ≥ 0,4. Sedangkan hasil validitas diskriminan menunjukkan bahwa tiap domain yang diujikan lebih besar nilainya dari domain lain. Berdasarkan uji Known Group Validity menunjukkan nilai p ≥ 0,05 artinya bahwa kuesioner tersebut tidak dapat membedakan secara signifikan antara pasien hipertensi dan pasien komplikasi, antara laki-laki dan perempuan, dan antara pasien usia 40-49 tahun, 50-59 tahun, 60-65 tahun. Kuesioner SF-36 versi Indonesia dengan susunan pertanyaan yang baru dapat digunakan untuk mengukur kualitas hidup pasien hipertensi.
