“…The treatment efficacy of the adapted MFT model was assessed using a two-group pre-and post-comparison study design (Judd, Smith, & Kidder, 1991). Since the details of the study have been previously described elsewhere (Ma et al, 2018;, here we summarise the research outcomes: (a) parents in the experimental group (EG) who had gone through MFT reported a significant change in perception of children's symptoms from pre-treatment to post-treatment, that is, the parental view of the ADHD symptoms was less pathological and less serious, whereas parents in the control group (CG) who had merely attended psychoeducational talks did not experience a similar change (Ma et al, 2018); (b) MFT had a different impact on fathers and mothers, with fathers in both the EG and the CG reporting a significantly better father-son relationship at post-treatment than pretreatment; in contrast, while the EG mothers' parental efficacy significantly increased from pre-treatment to post-treatment, no significant change was found in parental efficacy for the CG mothers (Lai et al, 2018); (c) the father's active involvement in treatment enhanced the father-child relationship irrespective of the type of treatment provided (Lai et al, 2018); and (d) children with ADHD in both the EG and the CG reported no significant change in perceived competence, hope, and parent-child relationship from pre-treatment to post-treatment (Ma, Lai, Wan & Xia, 2019).…”
