highly significantp < 0.001
The unidimensional structure of ESSI displayed a highly significant Satorra–Bentler scaled chi-square ( S-B χ2 = 119.15; df = 9 p < 0.001) and a value of RMSEA greater than 0.05 (0.101, 90% CI = 0.850–0.117), although other fit indices (CFI = 0.961, SRMR = 0.026) indicated approximation to adequacy of the model fit.
