Grouped t tests were used to compare the
mean change
in scores
in the control and intervention groups where the
differences were normally distributed (ECBI intensity score,
SDQ total score, PSI parent child interaction, and parent domains), and Mann - Whitney U tests for the
mean change
in scores
in the two groups where the
differences were not normally distributed (ECBI problem score,
SDQ conduct, hyperactivity, emotional, peer and prosocial scales, GHQ somatic anxiety, social, depression and total scores, PSI difficult child domain and total score, and SES).
