Abstract

This research aims to develop and test the construct validity of the tadzkiyatun nafs instrument at the Tarbiyah and Teacher Training Faculty of UIN Raden Intan Lampung. The Population of this research was the students of Tarbiyah and Teacher Training Faculty that consisted of 150 students. The method employed in this research was survey technique by using Likert Scale parameter. The result of the empirical research states that 37 items of the Tadzkiyatun Nafs instrument are spread out into five dimensions. The result of construct validity by using factor analysis proved that several numbers of items that have been estimated are 37 indicators with the value of > 0.30, out of 39 items, assuming that all items are estimated in accordance with the theory being constructed. The two other indicators are < 0.30 which then eliminated. The two items that were eliminated are item A4 on the Tauhid dimension, and point A11 on the shalat dimension. The implications of this research are expected can contribute to the progress of Islamic civilization, especially in relation to scientific integration by integrating Islamic sciences as its subject, and exact science as its methodology.

Abstract

This study aims to measure the spiritual competency construct of members of the Indonesian National Police. The population in this study comprises 323 police members, including 267 male and 56 female officers. The method in this study uses a Likert-scale survey. The study's results empirically indicate that the 37 items of the instrument measuring spiritual competence are distributed across three dimensions. The results of the construct validity using factor analysis indicate that a number of items have been successfully estimated as seven indicators, with factor loadings>0.50. Of the 37 existing items, based on the MSA number, all have been above 0.5. As for the second stage, the assessment based on the loading factor, there were 11 items that fell because they did not meet the requirements. The other 26 items were declared valid based on the consolidation analysis, with factor loadings>0.50.

Abstract

Purpose – Spiritual competence is an important aspect of the teaching and learning process. This study aims to evaluate the psychometric properties of a spiritual competence instrument for madrasah teachers, including its unidimensionality, local independence, item fit, and reliability. The instrument consists of three dimensions: ulul albab, akhlakul mahmudah, and tasamuh, and was analyzed using the Rasch model. Design/methods/approach - This study employed Gable's affective instrument development approach. The sample comprised 375 madrasah teachers, including 177 male and 198 female teachers. Using a multistage cluster sampling technique, participants were drawn from four major cluster areas in Banten Province: Tangerang Regency, Serang City, Pandeglang Regency, and Cilegon City. Data were analyzed using the Rasch model, including tests of unidimensionality, local independence, item fit, Wright map analysis, reliability testing, and item information function analysis. Findings – Empirical findings based on the Rasch model confirmed that the items measuring the spiritual competence of madrasah teachers were valid and reliable across the three dimensions. The results showed that 20 of the 23 items met the fit criteria (MNSQ: 0.5–1.5; PTMEA: > 0.40). The item reliability was 0.99 (excellent), respondent reliability was 0.76 (moderate), and Cronbach's alpha was 0.77. The Rasch model explained 44.2% of the total raw variance, while the first contrast in the unexplained variance accounted for only 7.1%, which is below the 15% threshold for unidimensionality. Research implications/limitations – Although the instrument demonstrated satisfactory psychometric properties among teachers in Banten Province, cross-validation in other provinces is still needed. Originality/value – The findings provide empirical evidence regarding the reliability of the spiritual competence instrument for madrasah teachers and support its use for both research and assessment purposes.
