Using the Exploration Factor Analysis (EFA) to Measure the Validity and Reliability for Da'wah Approach of Jemaah Tabligh

The Jemaah Tabligh dakwah approach study uses quantitative studies based on the Structural Equation Model (SEM) to analyze the various relationships between variables in the model. This study aims to develop and verify the validity and reliability of the instrument using the Exploration Factor Analysis (EFA) to measure the construction of religious charities, religious knowledge, method of delivery and emotional intelligence in the field of dakwah. This study has adapted the instruments developed by some earlier researchers, and also modified some statements in accordance with current studies. Therefore, it is necessary to re-run the Analysis of Factor Analysis of the Exploration (EFA), as the current study area may differ from previous studies, or the current study population is far different from previous studies in terms of socio-economic status, ethnicity and culture (Awang, 2010). Overall, the findings revealed that 15 items were abolished after the EFA was implemented. Only the reduction of items for the construction of the Ibadah Amal only, is 15 items. This reduction is due to a number of things that have been built before, no longer suitable for current studies or there are different item structures in current studies compared to previous study structures. The researchers need to recalculate the value of Internal Indicators of the current instrument for the new Alpha Cronbach value. Based on Awang's suggestion (2010; 2012), researchers decided to carry out the EFA re-item to measure the construction and in this study will be described in detail the procedure for conducting an EFA analysis for each construction.
