Latar belakang Subjective well being merupakan salah satu pengalaman subjektif yang dapat digunakan sebagai indikator outcome pengobatan pada pasien skizofrenia. Beberapa instrumen untuk menilai subjective well being telah dikembangkan, tetapi belum banyak instrumen subjective well being yang dikembangkan khusus pada pasien skizofrenia. Subjective Well Being under Neuroleptic Treatment-Short Form (SWN-S) dikembangkan secara spesifik untuk menilai subjective well being pasien skizofrenia. Namun, SWN-S belum divalidasi ke dalam bahasa Indonesia sehingga belum diketahui validitas dan reliabilitasnya. Tujuan Untuk mengetahui validitas dan reliabilitas instrumen Subjective Well Being under Neuroleptic Treatment-Short Form (SWN-S) versi Indonesia. Metode Penelitian ini merupakan penelitian non-eksperimental dengan rancangan cross-sectional. Subyek penelitian ini adalah pasien skizofrenia di bagian rawat jalan psikiatri RSJ Grhasia DIY. Instrumen yang diteliti adalah Subjective Well Being under Neuroleptic Treatment-Short Form (SWN-S). Uji validitas meliputi validitas isi dan konstruk. Uji reliabilitas dengan menghitung nilai internal consistency (Crönbach alpha). Hasil Hasil uji validitas konstruk dengan korelasi Pearson Product Moment menunjukkan bahwa semua item memiliki r hitung lebih dari r tabel ( r > 0,190). Analisis faktor menunjukkan bahwa kelima faktor menjelaskan 59,49% dari keseluruhan konstruk instrumen SWN-S. Hasil uji reliabilitas konsistensi internal instrumen SWN-S didapatkan nilai Cronbach�s alpha 0,817. Kesimpulan Subjective Well Being under Neuroleptic Treatment-Short Form (SWN-S) versi Indonesia adalah instrumen yang valid dan reliabel dalam menilai subjective well being pasien skizofrenia.

Background Subjective well being is one of the subjective experiences that can be used as an indicator of treatment outcome in schizophrenic patients. Subjective well being is increasingly recognized as an important treatment outcome in schizophrenic patients and is widely used in clinical settings. Some instruments for assessing subjective well being have been developed, but few subjective well being instruments have been developed specifically in schizophrenic patients. Subjective Well Being under Neuroleptic Treatment-Short Form (SWN-S) was developed specifically to assess subjective well being of schizophrenic patients.However, SWN-S has not been validated into Indonesian so it is not known the validity and reliability. Objective To find out the validity and reliability of the Indonesian version of the Subjective Well Being under Neuroleptic Treatment-Short Form (SWN-S) instrument. Methods This was a non-experimental study with cross-sectional design. The subject of this study is schizophrenia patients in the outpatient psychiatric RSJ Grhasia DIY. The instrument under study is Subjective Well Being under Neuroleptic Treatment-Short Form (SWN-S). Validity test includes content and construct validity test. Reliability test by calculating the internal consistency value based on Cronbach�s alpha. Results The result of construct validity test with Pearson Product Moment correlation shows that all items have r count more than r table (r> 0.190). Factor analysis shows that the five factors account for 59,49% of the overall SWN-S instrument construct. SWN-S instrument internal consistency reliability test results obtained Cronbach's alpha value 0.817. Conclusion Indonesian version of Subjective Well Being under Neuroleptic Treatment-Short Form (SWN-S) is a valid and reliable instrument in assessing subjective well being of schizophrenic patients.
