Abstract

Abstract The role of a caregiver often demands significant sacrifices in terms of time, thought, emotions, and energy, leading to various physical and psychological issues. Therefore, a valid and reliable measurement tool is needed to accurately assess caregiver burden. The Zarit Burden Interview (ZBI) is one such tool that is frequently used and has been shown to be valid and reliable in various countries and ethnic groups. However, in Southeast Asia, particularly in Indonesia, there has been limited research on the reliability of the ZBI. This study aims to evaluate the validity of the ZBI within the cultural context of Indonesia using Rasch Model analysis. The study involved 305 caregivers selected through convenience sampling, with the ZBI consisting of 22 items. The analysis showed a Cronbach's alpha value of 0.93, indicating high reliability. The Wright Map indicated a moderate level of item difficulty. Bias was found in item 21 based on gender, items 6 and 8 based on age, items 7, 11, and 12 based on caregiving duration, and items 6, 7, and 18 based on geographic location. Overall, the Indonesian version of the ZBI was shown to be valid and reliable in measuring caregiver burden. Keywords: Zarit Burden Interview, Rasch Model, Validity. Abstrak Peran sebagai caregiver seringkali menuntut pengorbanan besar dalam hal waktu, pikiran, perasaan, dan tenaga, sehingga menimbulkan berbagai permasalahan fisik dan psikologis. Oleh karena itu, diperlukan alat ukur yang valid dan reliabel untuk mengukur beban caregiver secara akurat. Zarit Burden Interview (ZBI) adalah salah satu alat yang sering digunakan dan telah terbukti valid serta reliabel di berbagai negara dan kelompok etnis. Namun, di Asia Tenggara, khususnya di Indonesia, belum ada penelitian mendalam mengenai keandalan ZBI. Penelitian ini bertujuan mengevaluasi validitas ZBI dalam konteks budaya Indonesia menggunakan analisis Model Rasch. Penelitian melibatkan 305 caregiver yang dipilih melalui convenience sampling, dengan ZBI yang terdiri dari 22 butir. Hasil analisis menunjukkan nilai alpha Cronbach sebesar 0,93, yang menunjukkan reliabilitas tinggi. Wright Map mengindikasikan tingkat kesulitan item yang sedang. Ditemukan bias pada item 21 berdasarkan gender, item 6 dan 8 berdasarkan usia, item 7, 11, dan 12 berdasarkan lama perawatan, serta item 6,7, dan 18 berdasarkan lokasi geografis. Secara keseluruhan, ZBI versi Bahasa Indonesia terbukti valid dan reliabel dalam mengukur beban caregiver.
