Uji Validitas dan Reliabilitas Instrumen Self-Report Version Of Zanarini Rating Scale For Borderline Personality Disorder (ZANBPD:SRV) Versi Bahasa Indonesia = Validity and Reliability Study of the Self-Report Version Of Zanarini Rating Scale For Borderline Personality Disorder (ZAN-BPD: SRV) in Indonesian Version.

Latar Belakang: Prevalensi penderita gangguan kepribadian ambang di komunitas umum, di setting rawat jalan, dan rawat inap secara berturut-turut diperkirakan sebesar 1-1,6%, 12-15% dan 22-25%. Kondisi GKA membuat individu rentan terhadap stresor kehidupan yang berkaitan dengan berbagai dampak negatif pada relasi interpersonal dan sosial, menurunnya produktivitas kerja dan kualitas hidup, tingginya komorbiditas gangguan jiwa lainnya termasuk penyalahgunaan zat, hingga tingginya risiko kematian. Tingkat kematian akibat bunuh diri pada GKA didapatkan lebih tinggi dari angka populasi umum yaitu sebesar 7,8%. Namun instrumen untuk menilai tingkat keparahan GKA belum ada di Indonesia. Oleh karena itu, uji validitas dan reliabilitas instrumen Self-Report Version Of Zanarini Rating Scale For Borderline Personality Disorder (ZAN-BPD:SRV) Versi Bahasa Indonesia diperlukan untuk menghasilkan suatu instrumen yang sahih dan andal dalan menilai tingkat keparahan GKA. Metode: Penelitian ini menggunakan desain uji validitas dan reliabilitas berupa desain cross-sectional yang dilakukan sejak Agustus 2023 hingga Oktober 2024. Sampel penilitian adalah dewasa berusia 18-59 tahun. Uji coba pilot melibatkan 20 subjek dewasa dan uji lapangan melibatkan 103 subjek dewasa. Penilaian uji validitas isi dilakukan melalui penilaian face validity melalui diskusi kelompok dan penilaian SCVI/Ave yang melibatkan 5 pakar. Uji validitas CFA menggunakan parameter dengan estimator DWLS melalui aplikasi JASP for Mac dan uji reliabilitas menggunakan penilaian Cronbach Alpha melalui software SPSS. Hasil: Nilai S-CVI/Ave sebesar 0,9. Hasil analisis CFA didapati Chi-square p > 0,05. Indeks kesesuaian model CFI sebesar 0,993, TLI sebesar 0,991, RMSEA sebesar 0,044 dan SRMR sebesar 0,059. Penilaian reliabilitas mendapatkan nilai total Cronbach’s alpha sebesar 0,773. Karakteristik demografi berupa jenis kelamin perempuan menunjukkan gejala GKA lebih intens hampir pada semua domain. Gambaran komorbiditas gangguan jiwa tidak memberikan perbedaan tingkat keparahan gejala GKA yang bermakna, dengan nilai p > 0,05 pada semua domain. Simpulan: Instrumen ZAN BPD: SRV versi Bahasa Indonesia terbukti sahih dan andal karena memilki nilai hasil uji validitas isi, uji validitas konstruk hingga uji reliabilitas yang baik. Adanya perbedaan intensitas gejala pada laki-laki dan perempuan didasari karena faktor biopsikososial. Komorbiditas gangguan jiwa memiliki fenomenologi yang beririsan dengan GKA namun tidak secara langsung memengaruhi derajat keparahan GKA yang diukur dengan instrumen ZAN BPD: SRV versi Bahasa Indonesia.

Background: The prevalence of borderline personality disorder (BPD) is estimated at 1–1.6% in the general population, 12–15% in outpatient settings, and 22–25% in inpatient settings. Individuals with BPD are particularly vulnerable to life stressors, which can lead to a range of adverse outcomes including impaired interpersonal and social relationships, decreased occupational productivity and quality of life, high rates of comorbid psychiatric disorders such as substance use disorders, and an elevated risk of mortality. The suicide mortality rate among individuals with BPD is notably higher than that of the general population, reaching approximately 7.8%. However, there is no instrument available in Indonesia to assess the severity of BPD. Therefore, a validity and reliability test of the Indonesian version of the Self-Report Version of the Zanarini Rating Scale for Borderline Personality Disorder (ZAN-BPD: SRV) is needed to provide a valid and reliable tool for assessing BPD severity. Methods: This study employed a cross-sectional design to assess the validity and reliability of the instrument, conducted from August 2023 to October 2024. The study sample consisted of adults aged 18–59 years. A pilot test was conducted with 20 adult participants, while the field test involved 103 adult participants. Content validity assessment was performed through face validity discussions and calculation of the SCVI/Ave involving five experts. Construct validity was evaluated using CFA with the DWLS estimator via the JASP for Mac software, while reliability was assessed using Cronbach's alpha with SPSS. Results: The S-CVI/Ave score was 0.9. The results of the CFA analysis found Chisquare p> 0.05. Model fit indices were as follows: CFI = 0.993, TLI = 0.991, RMSEA = 0.044, and SRMR = 0.059. The total Cronbach's alpha coefficient for reliability was 0.773. In terms of demographic characteristics, female participants exhibited more intense BPD symptoms across nearly all domains. Psychiatric comorbidities did not significantly affect BPD symptom severity, with p-values > 0.05 across all domains. Conclusion: The Indonesian version of the ZAN-BPD: SRV instrument is valid and reliable, as indicated by satisfactory content validity, construct validity, and reliability assessments. Differences in symptom intensity between male and female participants may be attributed to biopsychosocial factors. Although psychiatric comorbidities share overlapping phenomenology with BPD, they do not significantly influence the severity of BPD symptoms as measured by the Indonesian version of the ZAN-BPD: SRV.
