Why Clinicians Choose Their Language Intervention Approach: An International Perspective on Intervention for Children with Developmental Language Disorder

Purpose: Considerable progress has been made in recent years in generating external evidence underpinning interventions for children with developmental language disorder (DLD), but less is known about the practitioner decision-making process underpinning such interventions and whether such decisions are context specific or are internationally generalizable. Methods: An online survey about clinical practice was developed by members of COST Action IS1406, an EU-funded research network, which included representation from 39 countries. The participants were 2,408 practitioners who answered questions in relation to their decision making for a specific child of their choosing with DLD. Analysis of open-ended questions was undertaken, and data were converted into codes for the purpose of quantitative analysis. Results: Although a wide range of intervention approaches and rationales were reported, the majority of responses referenced a client-centred approach. Level of functioning was used as a rationale only if a child had severe DLD. Practitioners with university level education or above were less likely to report basing intervention on client-centred factors. A number of differently named interventions with variable theoretical and empirical underpinnings were used in different countries. Conclusions: Specific client and practitioner characteristics have an impact on the intervention approaches and rationales adopted across countries. A limited number of practitioners reported use of external scientific evidence, which suggests that there should be more initiatives in basic training of practitioners and continuing professional development to encourage the uptake of scientific evidence-based practice.
