Abstract : Unit trust investments are a collective savings approach that can generate returns for the future. The unique nature of unit trust sales in Malaysia requires the involvement of qualified consultants and other factors that influence an individual’s intention to invest in Islamic unit trusts. In this study, the preparation of instruments has been adapted from the literature, drawing on theories and models employed in previous studies. The primary objective of this study is to assess the validity and reliability of the readiness instruments adapted to meet the study’s requirements. The testing of readiness instruments through validity and reliability processes is crucial for producing consistent results. A total of five experts were appointed as assessors for the content validity of the instrument, including one industry expert serving as a face validity assessor. The content validity of the instrument was measured using the Content Validity Index (CVI), which determined whether items should be retained or modified. The reliability of the readiness instrument was evaluated using Cronbach’s alpha. The results indicated that all items were well-scored and did not require revision. The Cronbach’s alpha coefficient value for this study instrument was found to be high, indicating a strong level of reliability. Overall, the items in this instrument can be used effectively to address the study’s objectives and questions, and may be refined further for future studies.
