RELIABILITY AND VALIDITY MEASUREMENT OF EMOTIONAL INTELLIGENCE, SELF-COMPASSION AND PSYCHOLOGICAL WELL-BEING AMONG NGO VOLUNTEERS

Reliability and validity are important components to be focused on in conducting research. According to previous research, psychometric properties of emotional intelligence, self-compassion and psychological well-being not widely tested by the sample of volunteers. The aim of this study is to examine the reliability and validity for three instruments: Emotional Competence Inventory (ECI), Self-compassion Scale (SCS) and Scale of Psychological Well-being (SPWB). This study is conduct using quantitative research design by using questionnaires. There were 377 volunteers of NGO in Sabah involved as sample in this study. The data was analyzed by Statistical Packages for Social Science (SPSS) version 29. Results show that the score of Cronbach’s alpha for ECI is 0.972; while for SCS is 0.848 and for SPWB is 0.764. The results show that three instruments used in this study are reliable. Meanwhile for validity, the correlation coefficients between each subscales and overall scores of ECI components or the value of r, vary from 0.907 to 0.973, showing statistical significance at a level of p<0.05. For instrument SCS, the value of r for the subscales are between 0.488 and 0.773 with the p<.05. While for SPWB, the value of r of every subscales are between 0.574 and 0.823 with the p<.05. In conclusion, the three instruments used in this research show the value of r of all items very beneficial and strongly valid. All of the items from these three instruments remain. The implication of this study is that the findings could serve as a reference to future works for researchers that are interested in measurement studies of emotional intelligence, self-compassion and psychological well-being, especially in volunteer context.
