Digital Cognitive Behavioral Therapy Reduces Heavy Drinking Among a Non-Treatment Sample of People With Alcohol Use Disorder: A Feasibility Trial With CBT4CBT.

Public involvement in research is ‘an active partnership between patients, carers and members of the public with researchers that influences and shapes research’ [], no pagination]. The value of PPIE is underpinned by a moral and democratic view of the necessity of representation of voices from populations who may ultimately be affected by the research findings []. There is growing international interest in patient and public involvement and engagement (PPIE) []. PPIE is, however, well embedded in applied health care research in the United Kingdom (), with PPIE a requirement of some UK research funders. Statistical methods are fundamental to good‐quality health research and crucial for informing evidence‐based clinical practice and policies. Statistical methodology research involves the development, evaluation or comparison of statistical methods for the design or analysis of research studies. Using the correct statistical methods and finding novel ways to analyse data can have far‐reaching relevance to the study of different health conditions, therapies and clinical decision‐making processes. The impact of statistical methodology research can be wide‐reaching—such as reducing the sample size required to answer a specific research question, enabling more precise estimation of results or preventing bias, or preventing clinicians from drawing erroneous conclusions due to an incorrect analysis approach. Although challenges remain, there are excellent examples of how patients and the public have become meaningful partners in applied health research, ensuring that the research is of good quality, understandable and relevant to those that it impacts. However, there are fewer examples of impactful PPIE in statistical methodology research compared to applied health research []. Yet, case studies suggest that PPI can have benefits, including improved model structures and identification of data issues []. The Medical Research Council (MRC) published a review of public involvement in non‐clinical health and biomedical research, within which statistical methodology research falls. The review highlights the equal importance of public involvement in both clinical and non‐clinical health research, and provides recommendations for improving practice [].
