Parent-Implemented Hanen Program It Takes Two to Talk^®: An Exploratory Study in Spain

Parent-implemented interventions are a highly common approach for enhancing communication and linguistic abilities of late talkers, involving a population that shows a small expressive vocabulary in the absence of other deficits that could explain it. This study aimed to compare the outcomes of a parent-implemented language intervention, It Takes Two to Talk^®-The Hanen Program^® for Parents (ITTT), to a clinician-directed therapy. Participants were 17 families and their late-talking children: 10 families took part in ITTT and 7 in the clinician-directed modality. The outcomes in the social communication domain were more favorable for the ITTT group, but there were no significant differences between groups as regards vocabulary and syntax. In terms of parents, the research focused on examining if there were significant changes in parents' stress and their perceptions of their children's communication abilities. No differences were observed in the level of stress. In contrast, the group that received the ITTT program significantly altered their perceptions of their children's communication difficulties in comparison with the clinician-directed therapy. These results have implications in the clinical management of late-talking children, and they are discussed in terms of evidence-based practice.
