Plain English Summary
Background and study aims
Strong language skills underpin children’s educational achievement, and have been found to be predictive of both social and scholastic success. Research identifies the home learning environment as the bedrock for children’s early language development, and there is a need to support families to foster positive parent-child interactions and supportive home environments that enrich children’s early language learning opportunities. There is a trend for children from lower socioeconomic status (SES) backgrounds to show early language weaknesses that are often predictive of later language outcomes. The Talking Together programme is a 6-week home-based intervention that aims to address this need by teaching parents about early language development, and providing practical support for how to support children’s language learning. The programme was designed by BHT Early Education and Training, and is delivered by Language Development Workers (LDWs); early years practitioners with extensive training in early language development. This feasibility study aims to provide an in depth understanding of the intervention, outcome measures, and trial procedures, in order to inform a later full-scale trial.
Who can participate?
Parents/carers of 2-3 year old children who have been identified as having language weaknesses by the LDWs are eligible to receive the intervention. In order to be part of the feasibility RCT, the participating child must also be no older than 2 to 2.5 years at the time of their referral, they must be learning a language at home that is spoken by a member of the LDW team (to avoid the use of interpreters), and they should have no known sensory or developmental disorders.
What does the study involve?
All eligible families are randomly allocated to one of two groups; the first group receive the Talking Together programme immediately, and the second receive the intervention after a 6-month wait, if the child still requires the programme at that point. During the waiting period, the control group receive a packet of information and activities to support children’s language development that they can use independently. As part of standard practice, assessments of children’s language as well as the parent-child relationship, the home environment, and children’s behaviour are carried out in the first and final week of the intervention, as well as at a 6-month follow-up. To ensure that the control group mirrors standard practice, the families in this condition are also visited and assessed at these times.
What are the possible benefits and risks of participating?
The possible benefit for families taking part in the study is that the programme has a meaningful impact on the home language environment, and this results in improvements in children’s language skills. Although no serious risks are anticipated, there is a risk that if the programme is effective, families in the waiting control group are disadvantaged by receiving the programme at a later point in their child’s development.
Where is the study run from?
The programme is delivered by BHT Early Education and Training in Bradford (UK)
When is the study starting and how long is it expected to run for?
September 2018 to February 2021
Who is funding the study?

Feasibility controlled trial of Talking Together: a targeted home-based intervention to support children’s early language development
Rationale: This is a feasibility study to assess the feasibility and suitability of potential methods for conducting a randomized control trial of the Talking Together intervention. As this is a feasibility study, hypotheses related to intervention outcomes are not appropriate. However, the study will assess aspects of trial design and how appropriate they are to the specific context of this intervention, with the aim of informing a future full scale RCT of the programme.

Early language development in children aged 2-3 years
Families eligible for the Talking Together trial will be randomized to either immediate intervention or a waiting control by data analysts outside of the research and project team. The waiting control group will receive the intervention in the same way as the immediate intervention group, but at a 6 month delay to allow for post-test and follow up in the intervention group.
The Talking Together programme is a 6-week intensive training course delivered by Language Development Workers (LDWs; early years practitioners with extensive training in children’s language development). The programme takes a two-stepped approach to intervention. Firstly, a universal language screening is provided to the community. From this screening, LDWs identify families who may benefit from the programme based on both child factors (i.e. weak language development) and parent or home characteristics (e.g. parent-child interaction, a lack of developmentally appropriate materials in the home).
Primary outcome measure
The feasibility of a future, full-scale trial of the Talking Together programme:
1. Recruitment and retention of Talking Together by establishing the number of participants who were identified, eligible, approached, consented, randomised, completed the programme, and followed up 6 months after baseline [within 24 months of the beginning of the start date]
2. Representativeness of those participants eligible and recruited to the trial as compared to the wider population receiving the intervention based on key demographic indicators [within 18 months of the beginning of the start date]
3. Acceptability of the intervention and trial procedures for practitioners and families, including randomisation and completion of outcome measures [within 24 months of the beginning of the start date]
4. The most appropriate primary outcome measure for future full-scale RCT by considering the acceptability, reliability, and data quality (completeness) of currently administered outcome measures [within 24 months of the beginning of the start date]
5. Fidelity to the standardised procedures by assessing the intervention content, and the frequency and duration of support received by participants [within 18 months of the beginning of the start date]
6. Barriers and facilitators to engagement with the intervention and the trial [within 18 months of the beginning of the start date].
7. Time and resources required to train practitioners to administer the intervention, in order to make appropriate recommendations for resource requirements for full-scale RCT development [within 18 months of the beginning of the start date]
8. Intervention completion and attrition rates, along with outcome data group differences and variability across conditions, to inform sample size calculations for full-scale trial [within 30 months of the beginning of the start date]
The feasibility trial has the following progression/continuation criteria, and the results of these specific indicators will be used to inform the recommendation of whether to progress to full-scale RCT.
1. Recruitment – The proportion of participants identified and offered the intervention eligible to participate in the trial, and the number of these eligible participants who agree to participate in the trial. These numbers will be assessed cumulatively over the course of the recruitment phase:
1.1. Green - a minimum of 60% of participants are eligible, and a minimum of 50% of eligible participants participate
1.2. Red - less than 60% of participants are eligible, and less than 50% of eligible participants participate
2. Intervention adherence - The proportion of participants who are seen within 4 weeks of the specified assessment timepoints at all 3 assessment points (pretest, 2 month post-test, 6 month follow up):
2.1. Green - 80% of participants have compliant assessment schedules
2.2. Amber - 60-80% of participants have compliant assessment schedules
2.3. Red - less than 60% of participants have compliant assessment schedules
3. Outcome data – The proportion of the recruited participants with complete data at the 6 month follow up assessment point:
3.1. Green - 80% of participants have complete data
3.2. Amber - 70-80% of participants have complete data
3.3. Red - below 70% of participants have complete data
Secondary outcome measures
The outcome measures under consideration as part of the feasibility trial are all collected at pre-test and at 2 months (post-test) and 6 months (follow-up) post pre-test. All measures will be used throughout the recruitment phase with all participants:
1. Parent-child relationship, assessed using the Maternal Objects Relations Scale (MORS)
2. Home learning environment, assessed using the Home Learning Environment Questionnaire (HLEQ)
3. Child behaviour, assessed using the Strengths and Difficulties Questionnaire (SDQ)
4. Child vocabulary, assessed using Oxford Communicative Development Inventory, Short From (CDI)
5. Child broader language, assessed using the WellComm Assessment
