Problems with oral language skills in childhood have been linked with poor educational, employment, and mental health outcomes. In the UK, there is increasing concern about the oral language skills of children, particularly children from areas of social disadvantage. Research emphasises the importance of the home language environment as a fundamental bedrock for the development of oral language skills. It is vital, therefore, that support is available to help families in need to provide the optimal language environment for their child. Talking Together is a 6-week home visiting programme recently commissioned by Better Start Bradford to develop parents’ knowledge of the importance of a good language environment and help to improve parent-child interactions. This study represents the initial steps in developing a definitive trial of the Talking Together programme. This study is a two-arm randomised controlled feasibility study in which families referred into the Talking Together programme and consent to participate in the trial will be randomly allocated to either an intervention group or a waiting control group. We will assess the recruitment and retention rates, the representativeness of our sample, the appropriateness of our measures, and the sample size needed for a definitive trial. We will also carry out a qualitative evaluation to explore the acceptability of trial procedures for families and service providers, fidelity of delivery, time and resources for training, and barriers and facilitators to engagement with the programme. Clear progression criteria will be used to assess suitability for a definitive trial. This feasibility study will inform the development of a definitive trial of this home-based visiting programme, which will add to the sparse evidence base on which practitioners can draw when supporting families in need. The lessons learnt from this feasibility study will also inform the wider evaluation work of the Better Start Bradford Innovation Hub. The trial is registered with the ISRCTN registry: study ID ISRCTN13251954 . Date of registration: 21 February 2019 (the trial was retrospectively registered).

早期语言发展干预的随机对照可行性试验和定性评估：“一起交谈评估和结果的结果”（oTTer）项目的研究方案

儿童口语技能问题与教育、就业和心理健康状况不佳有关。在英国，人们越来越关注儿童的口语能力，尤其是来自社会弱势地区的儿童。研究强调家庭语言环境作为发展口语技能的基本基石的重要性。因此，提供支持以帮助有需要的家庭为他们的孩子提供最佳语言环境至关重要。Talking Together 是一项由 Better Start Bradford 最近委托开展的为期 6 周的家访计划，旨在培养父母对良好语言环境重要性的认识，并帮助改善亲子互动。这项研究代表了开发“一起交谈”计划的最终试验的初步步骤。这项研究是一项双臂随机对照可行性研究，其中提到一起交谈计划并同意参加试验的家庭将被随机分配到干预组或等待对照组。我们将评估招募和保留率、样本的代表性、测量的适当性以及最终试验所需的样本量。我们还将进行定性评估，以探索家庭和服务提供者对试验程序的可接受性、交付的真实性、培训的时间和资源，以及参与该计划的障碍和促进者。明确的进展标准将用于评估对最终试验的适用性。这项可行性研究将为这项以家庭为基础的访问计划的最终试验的发展提供信息，这将增加从业者在支持有需要的家庭时可以借鉴的稀少证据基础。从这项可行性研究中吸取的经验教训也将为 Better Start Bradford 创新中心的更广泛的评估工作提供信息。该试验已在 ISRCTN 注册中心注册：研究 ID ISRCTN13251954。登记日期：2019年2月21日（试验追溯登记）。这将增加从业者在支持有需要的家庭时可以借鉴的稀疏证据基础。从这项可行性研究中吸取的经验教训也将为 Better Start Bradford 创新中心的更广泛的评估工作提供信息。该试验已在 ISRCTN 注册中心注册：研究 ID ISRCTN13251954。登记日期：2019年2月21日（试验追溯登记）。这将增加从业者在支持有需要的家庭时可以借鉴的稀疏证据基础。从这项可行性研究中吸取的经验教训也将为 Better Start Bradford 创新中心的更广泛的评估工作提供信息。该试验已在 ISRCTN 注册中心注册：研究 ID ISRCTN13251954。登记日期：2019年2月21日（试验追溯登记）。
