Understanding the Context and Needs of Adolescents Experiencing Subclinical Anxiety and Depression Symptoms in Wales:...

This study aimed to understand the context and needs of adolescents experiencing elevated but subclinical anxiety and depression symptoms, who have been termed the "missing middle" in Wales (UK). It is part of a project to identify and adapt an effective secondary school-based intervention to Wales. The methods used were document analysis, and qualitative primary data collection. Sixteen documents were analysed: Welsh policy (n = 2), primary research (n = 3), research overviews (n = 2), and reports of stakeholders' views on adolescent mental health (n = 9). Next, focus groups and interviews were conducted with 35 students aged 11-18 years old; 18 school staff; 23 practitioners involved in managing, delivering or referring to non-clinical and clinical mental health services; and two policy officials. A hybrid approach of deductive and inductive thematic analysis was conducted which produced four themes. Firstly, we identified definitions and understandings of the "missing middle". Secondly, contextual factors included an increase in help seeking, alongside challenges of self-diagnosis and the striving for specialist support even when this was inappropriate. A third theme highlighted enablers and barriers to implementing targeted provision e.g., while funding had increased for school services, this was still not adequate to meet demand. Fourthly, desired intervention targets were at the intrapersonal (cultivating emotional regulation and problem-solving skills) and the interpersonal levels (reducing loneliness and supporting social relationships), with school-based, one-to-one delivery via external providers preferred. These findings offer insights into how preventive interventions should include those experiencing high levels of distress and/or functional impairment even in the absence of high symptoms.
