Developing a Conceptual Model for the Causal Effects of Outdoor Play in Preschools Using PLS-SEM

Abstract

This study attempts to establish the causal effects of outdoor play through a conceptual model consisting of six latent constructs. Seventy Penang preschool operators took part in a questionnaire survey conducted from June to July 2021. All of the 70 respondents agreed that outdoor play is important for children’s development even though only 62 respondents implemented outdoor play yards in their preschools. Raw data from these 62 respondents were used to develop the conceptual model by PLS-SEM. Measurement models were assessed by checking the indicator reliability, internal consistency reliability, convergent validity and discriminant validity. The structural model was assessed by checking the SRMR and NFI. The measurement models are found to be acceptable with AVE > 0.50 for all of the constructs and all of the 34 indicators have loadings > 0.50. However, there are 16 indicators with difference between loadings < 0.10, and the structural model does not have a good fit with SRMR > 0.10 and NFI < 0.90. Lack of discriminant validity could be remedied by removing eight indicators with difference between loadings < 0.10. Model fit could be improved with larger sample size since bootstrapping with 1000 iterations yielded SRMR = 0.098 at 95% for the saturated model. Seven significant paths were found among the six constructs in the final conceptual model.

“…Model fit in Smart PLS can be seen from the SRMR, d-ULS, and d_G values 73 . The difference that exists between the observed correlation and the matric model can be seen in the SRMR value.…”

“…The fit model in PLS-SEM can be analyzed from the Standardized Root Mean Square Residual (SRMR) and Normed Fit Index (NFI) values [ 81 , 82 ]. SRMR shows differences between relationships, which is considered a good fit measure in research models using PLS-SEM [ 62 ].…”

Extending unified theory of acceptance and use of technology to understand the acceptance of digital textbook for elementary School in Indonesia

“…The fit model in PLS-SEM is assessed seen from the SRMR and NFI values provided by the SMART-PLS software. According to Yew et al (2022), SRMR value should be less than or equal to 0.10, or at 0.08, to obtain a good fit. Furthermore, the NFI value, which has a relationship with the chi-square of the benchmark model, should be more than 0.8.…”
