Uji Kesahihan dan Keandalan Indeks Barthel Modifikasi Shah Versi Bahasa Indonesia dalam Penilaian Kemandirian Penderita Stroke.

Stroke merupakan salah satu penyebab disabilitas terbanyak di dunia. Stroke dapat mempengaruhi kemandirian penderita, termasuk dalam melakukan aktivitas kehidupan sehari-hari. Beberapa skala telah digunakan untuk menilai kemandirian penderita stroke, termasuk Indeks Barthel. Indeks Barthel Modifikasi Shah merupakan modifikasi Indeks Barthel yang dikatakan lebih sensitif terhadap perubahan kondisi pasien, sehingga lebih ideal digunakan dalam setting rehabilitasi. Thesis ini bertujuan untuk melakukan adaptasi transkultural dari Indeks Barthel Modifikasi Shah ke Bahasa Indonesia, dan kemudian menilai kesahihan dan keandalannya dalam menilai kemandirian melakukan aktivitas kehidupan sehari-hari pada penderita stroke. Proses adaptasi terdiri dari dua tahap, di tahap pertama dilakukan adaptasi transkultural dari Indeks Barthel Modifikasi Shah sesuai metode dari ISPOR. Hasil dari adaptasi transkultural kemudian diuji di tahap kedua pada 30 pasien stroke fase subakut hingga kronis, untuk mendapatkan kesahihan konstruksi, keandalan test-retest, dan keandalan interrater. Dari uji kesahihan konstruksi didapatkan korelasi kuat dari masing- masing domain terhadap total skor (0.788-0.949). Dari keandalan test-retest didapatkan Alpha Cronbach 0.988(0.942-1.000 untuk masingmasing domain) dan dari keandalan interrater didapatkan Alpha Cronbach 0.999(0.9631.000 untuk masing-masing domain). Dapat disimpulkan bahwa Indeks Barthel Modifikasi Shah versi Bahasa Indonesia memiliki kesahihan dan keandalan yang baik, dan dapat digunakan sebagai suatu skala alternative untuk menilai kemandirian melakukan aktivitas kehidupan sehari-hari pada penderita stroke.

The purpose of this paper is to do transcultural adaptation of Modified Barthel Index by Shah to Indonesian language, and to test its validity and reliability in measuring Activity of Daily Living in Stroke patient. The adaptation process was divided into two stages. In the first stage, transcultural adaptation of Modified Barthel Index by Shah was made, according to method by ISPOR. The result of transcultural adaptation was then tested in the second stage in 30 stroka patients, from subacute to chronic phase. Construct validity, test-retest reliability, and interrater reliability was tested. From construct validity test, strong correlation was made, correlation of each domain to total score was ranging from 0.788 to 0.949. In test-retest reliability, Alpha Cronbach of 0.988 of total score, and for each domain ranging from 0.942-1.000 was found. In interrater reliability, Alpha Cronbach of 0.999 of total score, and for each domain ranging from 0.963-1.000 was found.
