Abstract
This study aimed to examine levels of motivation, competency, and work performance efficiency, and to analyze the statistical relationships and predictive effects of motivation and competency on work performance efficiency among local government personnel. The sample consisted of 240 personnel from Koh Samui City Municipality, Surat Thani Province, with the sample size determined using Yamane’s formula (1973). A five-point Likert scale questionnaire was employed. Data were analyzed using descriptive statistics, Pearson correlation, and multiple regression analysis. The results indicated that motivation, competency, and work performance efficiency were rated highly, with mean scores ranging from 4.00 to 4.18. However, the distribution of scores was highly concentrated at the upper level, which may reflect a potential ceiling effect associated with self-reported questionnaires. Pearson correlation analysis revealed that both motivation and competency were positively correlated with work performance efficiency at a statistically significant level. The multiple regression analysis showed that motivation and competency jointly accounted for 61% of the variance in work performance efficiency (R2 = .61, p < .001). Among the predictors, competency demonstrated the strongest statistical influence (β = .54), followed by motivation (β = .32). These findings indicate statistical associations and predictive relationships rather than direct causal effects. The results suggest that enhancing both motivation and competence may be practical strategies for improving work performance efficiency among local government personnel.
