Uji Kesahihan dan Keandalan Instrumen Recovery Assessment Scale – Domains and Stages (RAS-DS) versi Bahasa Indonesia = Validity and Reliability of the Indonesian version of the Recovery Assessment Scale – Domains and Stages (RAS-DS).

Latar Belakang. Pemulihan adalah suatu proses yang dilalui orang dengan skizofrenia untuk mencapai perbaikan gejala dan berkembang hingga memiliki kehidupan yang bermakna. Saat ini tujuan tatalaksana kesehatan jiwa berorientasi untuk mencapai pemulihan dan belum ada instrumen penilaian pemulihan di Indonesia. Penelitian ini dilakukan untuk mendapatkan Recovery Assessment Scale – Domains and Stages (RASDS) versi Bahasa Indonesia yang sahih dan andal. Metode. Penelitian kesahihan dan keandalan dengan desain potong lintang, melibatkan 100 orang dengan skizofrenia dalam fase remisi, berusia 18-59 tahun, selama April 2017 hingga Oktober 2018. Uji kesahihan dilakukan untuk menilai kesahihan isi, kesahihan konstruksi, dan kesahihan sewaktu yang dibandingkan dengan instrumen Positive and Negative Syndrome Scale (PANSS) remisi. Uji keandalan dilakukan untuk menilai konsistensi internal dan tesretes. Hasil. Rerata lama pengisian instrumen adalah 10.59 (SB 5.08) menit dan tingkat kesulitan yang rendah. Hasil kesahihan isi Content Validity Index for Items sebesar 0.99 dan Content Validity Index for Scale sebesar 0.92. Angka korelasi kesahihan sewaktu adalah -0.639. Hasil Principle Component Analysis (PCA) adalah RAS-DS 33-butir, delapan matriks komponen dan jumlah kumulatif persentase varians 66.656%. Hasil koefisien Cronbach’s alpha sebesar 0.931 dan Intraclass Correlation Coefficient tesretes sebesar 0.982. Simpulan. RAS-DS versi Bahasa Indonesia dapat dikerjakan dengan cepat dan mudah, serta memiliki nilai psikometrik yang baik. RAS-DS versi Bahasa Indonesia 33-butir dapat mengukur proses pemulihan pada orang dengan skizofrenia dalam fase remisi.

Background. Recovery is a process through which a person with schizophrenia can achieve improvement of symptoms and develop a meaningful life. While the goal of mental healthcare is now oriented towards recovery, currently there is no instrument to assess recovery in Indonesia. The aim of this study is to obtain a valid and reliable Recovery Assessment Scale - Domains and Stages (RAS-DS) Indonesian version. Methods. This cross-sectional study involved 100 people with schizophrenia in symptomatic remission, aged 18-59 years, from April 2017 to October 2018. Validity tests were conducted to assess the content and construct validity. The instrument is compared to Positive and Negative Syndrome Scale (PANSS) to assess concurrent validity. Reliability testing was carried out to assess internal consistency and test retention. Results. Mean of time needed to complete the instrument is 10.59 (SD 5.08) minutes and difficulty level is low. Content Validity Index for Items is 0.99 and Content Validity Index for Scale is 0.92. Concurrent validity with PANSS is -0.639. Principle Component Analysis produced a 33-item RAS-DS, 8 component matrices, and explains 66.656% of variance. For reliability, Cronbach’s alpha is 0.931 and Intraclass Correlation Coefficient is 0.982. Conclusion. The 33-items RAS-DS Indonesian can measure recovery process in people with schizophrenia with good psychometric properties. The instrument can be completed quickly and easily.
