a trend towards significancep = .09
The longitudinal analysis using repeated measures ANCOVAs (covariates age and verbal IQ) showed a trend towards significance in the group effect ( F (3,95) = 3.19, p = .09), but no-significant effect of time ( F (1,95) = 1.21, p = .27) and also no significant group*time interaction for the MACH-IV total scores ( F (3,95) = 0.55, p = .65) ( Fig 2 ).
