Gastrointestinal quality of life index 10 (GIQLI-10) in Bahasa Indonesia: Translation and validation of a standardized questionnaire to assess patient symptoms

The Gastrointestinal Quality of Life Index (GIQLI-10) is a standardized measure of quality of life for gastrointestinal symptoms. Out purpose is translating and validating the GIQLI-10 to Bahasa Indonesia for use in the Indonesian population. Cases of gastrointestinal disease is rising in Indonesia, possibly due to changes in dietary patterns and infectious diseases. Therefore, it is necessary to adequately measure the symptoms of gastrointestinal diseases quantitatively and its impact on the quality of life of the patient. A simple and valid standardized questionnaire is necessary, which can be implemented in daily practice, requiring limited implementation time. GIQLI-10 is a tool to evaluate the quality of life of patients with gastrointestinal disorders, covering both their symptoms and overall well-being. However, as a closed-ended questionnaire, it may have limitations in capturing the full spectrum of individual patient symptoms and rely on subjective responses influenced by cultural factors. Despite these limitations, GIQLI-10 has been validated in various languages and populations, demonstrating its reliability and validity across different cultural backgrounds and diseases. The successful translation and validation of the GIQLI-10 into Bahasa Indonesia will facilitate its use in assessing the quality of life of Indonesian patients with gastrointestinal disorders, aiding diagnosis, treatment planning, and research. Our objective is to translate GIQLI-10 to Bahasa Indonesia and assess it’s reliability and validity. We used a standardized translation method recommended for medical questionnaires. The final version of the questionnaire was tested for its validity and reliability. Reliability was measured using Cronbach's alpha, which yielded a score of 0.714. Internal validity was assessed for each item using Pearson's correlations, which shows that the translated version is valid and reliable. This questionnaire can be implemented in a short duration, and applied to all patients with gastrointestinal symptoms.
