The tween years: A systematic literature review for services for children aged 10-13 years

To explore the literature about services and interventions provided to tween children as the basis for informing future practice and policy.

The tween years (10-13 years) is a period in human development where children experience rapid physical and mental development; their thinking and actions are influenced by peer pressure, risk taking, concerns about their body image, size, and gender, and may become victims to bullying and increasing levels of mental ill-health. It may also be a time of transition between schooling institutions. Despite the multiplicity of these factors, pre-adolescents appear to be receiving little attention from both service providers and policy makers.

Following the PRISMA reporting guidelines, a systematic search of peer-reviewed papers was conducted between June 2020 and April 2021. Studies were selected by screening their abstracts and titles. In total, 44 articles were included for in-depth analysis. Of these, 17 were randomised studies and 10 were non-randomised, and all were subjected to the assessment of risk of bias using the Review Manager Tool and ROBINS-I Tool respectively.

Data was extracted by type of service/intervention/program, country, and type of study/methodology, aim, sample size, age range, and findings. Data synthesis was performed using thematic analysis and content analysis. The results are presented in an outcome summary table highlighting the study's outcomes including the provided programs, their acceptability, and their impacts on factors such as anxiety and depression levels, change of attitude, behavioural control, weight loss, resilience and coping, emotional regulation, self-esteem, and improved well-being.

The majority of programs described in this review reported positive results, and as a result have the potential to make a valuable contribution to future practice, policy, and research involving the tweens.
