Abstract
Abstract Background Young adults not in education, employment, or training (NEET) represent a significant global issue, with varying challenges across different countries. Research indicates a strong association between NEET status and negative outcomes such as mental health difficulties, low self-esteem, and social exclusion, though the direction of causality is often complex and bidirectional. This scoping review aimed to provide a comprehensive mapping of international research on NEETs, including risk factors, characteristics, and effective interventions to inform future policy and practice. Methods This scoping review was conducted following the Joanna Briggs Institute (JBI) framework, incorporating the PRISMA-ScR checklist. The review included six key stages: identifying the research question, identifying relevant studies, selecting studies, charting the data, collating, Summarizing, and reporting the results, and consultation. A systematic search was conducted in PubMed, Scopus, and Web of Science, covering literature from 2021 to April 2024. Eligibility criteria were established using the population-concept-context (PCC) framework. Results A total of 159 studies were included, classified into 11 topics. The review identified a diverse range of factors that influence the status of NEET, including individual, family, and systemic elements. Key determinants such as cognitive abilities, noncognitive skills, and socioeconomic background were highlighted. Psychological issues, including mental health problems and low self-esteem, were prevalent among NEETs. Social issues such as inequality, discrimination, and social exclusion were also significant. The review found that NEET status is associated with long-term socioeconomic disadvantages, including lower educational attainment, higher unemployment rates, and increased mental health risks. The effectiveness of the interventions varied, some showing positive outcomes in terms of employment and mental health, while others had limited impact. Conclusions The NEET phenomenon is complex and requires a holistic approach that integrates the health, welfare and work life sectors. Effective interventions should be tailored to the specific needs of NEET individuals, considering their mental health, self-esteem, and social connections. Policymakers should focus on developing comprehensive support systems that address the diverse challenges faced by NEETs, ensuring sustainable transitions to education, employment, or training. More research is needed to explore the long-term effectiveness of various interventions and to identify best practices to support NEETs worldwide.
