Browne & Cudeck, 1993) and the standardized root mean square residual (SRMR; Bentler, 1995). We chose these two indices because the RMSEA is a commonly used index based on the non-centrality parameter, while the SRMR provides an estimate of observed to predicted covariance and is less redundant with the RMSEA than other commonly-used fit indices like the comparative fit index (CFI) or Tucker-Lewis index (TLI) which are also based on the non-centrality parameter.
