Psychometric Evaluation of the Primary School Students’ Perceived Teacher Trust Behavior Scale

Students' perceptions of trust behaviors demonstrated by teachers significantly correlated with their involvement in learning, academic motivation, and the formation of positive behaviors in the elementary school classroom environment. The objective of this study was to assess the psychometric nature of the Perceived Teacher Trust Behavior Scale (PTTBS), which serves as a measurement tool for students' perceptions of teacher trust behavior. This study used a quantitative approach that included 340 students from public elementary schools. Data was obtained through the PTTBS questionnaire which included four dimensions: emotional support, moral recognition, academic support, and competence recognition. Data analysis was carried out using SmartPLS 4 through the PLS-SEM approach, which combines Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA). The EFA results showed a KMO value of 0.789, CFA results showed that all outer loading was above 0.70, with a Composite Reliability value of > 0.80 and an Average Variance Extracted (AVE) value of > 0.50. The discriminant validity test using HTMT showed a value below 0.85. Discriminant validity assessment using HTMT showed a value below 0.85. The fit model index illustrates outstanding conformity with values of CFI = 1,000, TLI> 0.90, and SRMR = 0.032. These results suggest that PTTBS is a legitimate and reliable tool for measuring elementary school student’ perceptions of teacher trust behavior. This research strengthens the construction of PTTBS in the context of elementary schools in Indonesia and makes an empirical contribution to the use of PTTBS in educational research.
