"I know my knowladge is limited": Validating general intellectual humility scale using rasch analysis

Intellectual Humility is a construct that has been extensively studied over the past few decades, both conceptually froma philosophical perspective and empirically in terms of psychological measurement. This study aims to validate theGeneral Intellectual Humility (GIH) questionnaire in Indonesian sample. The GIH questionnaire consists of six itemsusing a Likert scale with 5 response options ranging from 1 (Strongly Disagree) to 5 (Strongly Agree). A total of 653undergraduate participants, aged between 17 and 24 years, from several universities in Indonesia, were included in thestudy. Participants were selected using a non-probability sampling technique. Confirmatory factor analysis (CFA) andRasch Partial Credit Model (PCM) analysis were applied in this study. The results indicate that the GIH scale data met allthe required Rasch analysis assumptions, including uni-dimensionality, local independence, item fit, and differential itemfunctioning (DIF). CFA analysis resulted that the GIH data fit to a unidimensional model, and all items were fit measuredGIH. The GIH questionnaire has good psychometric properties and can be used practically to measure intellectualhumility within a general domain.
