Notes: The pre-, post- and follow-up analyses of maternal and paternal sense of competence and parent–child dysfunctional interaction. Wilcoxon signed-rank tests were calculated; p values are one-tailed due to the directional hypotheses and Benjamini-Hochberg adjusted. Abbreviations: T1, pre-intervention; T2, post-intervention; T3, 3-month follow-up; T4, 6-month follow-up; T5, 12-month follow-up
