Abstract: A quasi-experimental study with a pretest-posttest and a control group. The study population included all mothers of mentally handicapped children in Iran under the supervision of a social welfare organisation. The study sample comprised 30 mothers divided into two groups. The experimental group took part in a NVC training programme for 8 sessions (90 minutes per session; twice a week), while the control group received no such training. The instrument used in the study was Pianta’s Mother-Child Interaction Scale (1992), which includes conflict components such as closeness and dependence.
Comment: There is a control group in this study, but they did not receive NVC training. It would have been ideal for the control group to have undergone other communication training in order to be able to distinguish the specific effects of NVC. In addition, the subjects were tested with explicit questionnaires on their mother-child interactions, which may create a bias in the reporting of those who had undergone the training, with a tendency to want to improve the results, out of complacency.
By studying changes in the conflict, closeness and dependence subscales as a function of group type, the authors increased their chances of finding a difference. To counteract this multiple-test bias, they used multivariate analyses.
Perspective: It would be relevant to evaluate the effects of this training at 6 months, for example, to measure the impact over the longer term. And to use implicit tests to avoid complacency bias.
