Validity and reliability of TASKA services quality instrument

Abstract

Survey questionnaires are one of the most extensively used data gathering approaches in social science research. In this research, the primary aim of a survey is to collect crucial data in the most precise and reliable method achievable. This study aims to determine the reliability and construct validity of the constructed instrument in determining the contributing components to TASKA service attribution. This article examines and covers the validity and reliability of a survey questionnaire and the many types of validity and reliability tests used in TASKA to measure service quality. 273 TASKAs were chosen using the proportionate stratified random selection approach from three states in Malaysia's Klang Valley. The measurement model's validity and reliability in the analysis utilizing the Structural Equation Modeling (SEM) method. The fit index (CMF)2 = 3230.541, with degrees of freedom (df) = 902, CMIN / df = 3.582 (5.0), CFI & TLI (0.9), and RMSEA = 0.070 (0.1), was used to fit the measurement models. According to the findings, all indices fulfil the standardized measure, and the assessment tool has proven to be beneficial. According to the research, five factors influence caretakers' evaluations of TASKA's service quality. With demographic factors like highest education level, profession, locality, home-TASKA range, type of agency, TASKA status, and child age helping to strengthen the TASKA selection factor, the management, kid’s growth, charges, routine activity, and managing cost creates a strong association that can be used to estimate a complete structured equation model. The TASKA service model, according to studies, can be used to enhance present quality and predict future developments. It can also be used as a module for providing the maximum degree of service to the attribution of the caretakers.
