The main aim of this study was to develop a comprehensive scale to
assess preschool teachers' self-efficacy to facilitate motor development
activities. Scale validation was assessed through content, construct, and
criterion validity, while reliability was determined through Cronbach's
alpha and test-retest analyses. It was found that the content validity ratio
of the items exceeded the threshold of 0.56 after content validity analysis.
In addition, the content validity index for the scale was calculated to be a
robust 0.903. A sample of 361 preschool teachers were then administered
the scale. Exploratory factor analysis (EFA) was performed on the data
obtained. The results of the EFA showed that the factor loading values
ranged from 0.52 to 0.83. Following the EFA, a confirmatory factor
analysis (CFA) was carried out, which resulted in a χ2/df value of 1.657.
Other goodness of fit indices were as follows: GFI=0.90, TLI=0.94,
IFI=0.95, CFI=0.95, RMSEA=0.043, SRMR=0.052. Overall, the scale
explained 51.242% of the total variance. Consequently, the initial form
was refined into a 27-item, 3-factor structure as a result of factor analysis.
In terms of the criterion validity analysis, a significant positive
relationship emerged between the scale and a comparable instrument
measuring a related construct. Furthermore, regarding reliability analysis,
the scale showed a high Cronbach's Alpha reliability coefficient of 0.88.
The scale's test-retest reliability was confirmed with an intraclass
correlation coefficient (ICC) of 0.77. In conclusion, this study provided a
scale that can be deemed both valid and reliable for the assessment of the
self-efficacy of preschool teachers in implementing motor development
activities
