Latar belakang. Skala Inflammatory Neuropathy Cause and Treatment (INCAT) motorik dan sensorik merupakan skala penilaian keterbatasan aktivitas sehari-hari dan keluhan sensorik pada pasien CIDP. Penelitian ini bertujuan untuk melakukan uji validitas dan reliabilitas skala INCAT motorik dan sensorik ke dalam bahasa Indonesia.Metode. Dilakukan adaptasi dan translasi kultural sesuai kaidah WHO, kemudian dilakukan uji validitas dan reliabilitas skala INCAT versi bahasa Indonesia. Populasi penelitian ini adalah semua pasien dewasa dengan diagnosis CIDP yang dirawat maupun berobat rawat jalan di RSCM yang memenuhi kriteria inklusi.Hasil. Tiga puluh satu subjek memenuhi kriteria inklusi. Sebagian besar laki-laki (56,60%). Usia berkisar antara 21 tahun sampai 77 tahun, dengan prevalensi tertinggi usia < 60 tahun. Pada uji validitas INCAT motorik pertama memiliki nilai antara 0,850-0,875, pada pemeriksa kedua didapatkan nilai 0,844 sampai 0,913. Pada uji validitas INCAT sensorik pertama didapatkan nilai antara 0,769-0,866. Pemeriksaan kedua didapatkan nilai 0,759 sampai 0,866. Hasil uji reliabilitas internal INCAT motorik pertama mendapatkan nilai 0,639 dan kedua mendapatkan nilai 0,717. Reliabilitas eksternal INCAT motorik didapatkan nilai 0,652 . Uji reliabilitas internal INCAT sensorik pertama mendapatkan hasil 0,837-0,875, kedua mendapatkan hasil 0,833-0,890 . Reliabilitas eksternal mendapatkan hasil 0,631. Waktu yang diperlukan untuk melakukan pengisian kurang dari 10 menit.Kesimpulan. Skala INCAT motorik dan sensorik versi bahasa Indonesia valid dan reliabel dalam mengevaluasi keterbatasan aktivitas dan keluhan sensorik pada pasien CIDP.

Introduction. The motor and sensory Inflammatory Neuropathy Cause and Treatment (INCAT) scale is a scale for assessing the limitations of daily activities and sensory complaints in CIDP patients. This study aims to test the validation and reliability of the motor and sensory INCAT scale into Indonesian languange.

Methods. Cultural adaptation and translation were carried out according to WHO rules, then the Indonesian version of the INCAT scale was tested for validity and reliability. The population of this study were all adult patients with a diagnosis of CIDP who were treated as well as outpatients at the RSCM who met the inclusion criteria.

Results. Thirty-one subjects met the inclusion criteria. Most of the men (56.60%). Age ranged from 21 years to 77 years, with the highest prevalence aged <60 years. In the first motor INCAT validity test, it has a value between 0.850-0.875, the second examiner gets a value of 0.844 to 0.913. In the first sensory INCAT validity test, values were obtained between 0.769-0.866. The second examination obtained a value of 0.759 to 0.866. The results of the first motor INCAT internal reliability test got a value of 0.639 and the second got a value of 0.717. External reliability of motor INCAT obtained a value of 0.652 . The first sensory INCAT internal reliability test got 0.837-0.875 results, the second got 0.833-0.890 results. External reliability results in 0.631. It takes less than 10 minutes to do the examination.

Conclussion. The Indonesian version of the motor and sensory INCAT scale is valid and reliable in evaluating activity limitations and sensory complaints in CIDP patients.
