It is estimated that almost 75% of all mental disorders manifest for the first time between the ages of 15 and 25.^{Reference Dooley and Fitzgerald1} It has also been reported that up to 20% of young people will experience an anxiety disorder or a depressive episode by the age of 18 years.^{Reference Werner-Seidler, Perry, Calear, Newby and Christensen2} Furthermore, the lifetime prevalence rates of non-suicidal self-injury (NSSI – the destruction of bodily tissue without suicidal intent)^{Reference Halicka and Kiejna3} among non-clinical samples of adolescents have been estimated to be 17.2%, compared with 5.5% in adults.^{Reference Swannell, Martin, Page, Hasking and St John4} The prevalence of NSSI among adolescents varies, from between 14 and 40% in community populations and 38 and 67% in psychiatric in-patient samples, making it a significant concern among youth.Reference Cloutier, Martin, Kennedy, Nixon and Muehlenkamp⁵ Suicidal ideation has been reported by 24.66% of adolescents aged 13–19 years.Reference Zygo, Pawłowska, Potembska, Dreher and Kapka-Skrzypczak⁶

One factor that has been demonstrated in a growing literature to be associated with high prevalence rates of mental health issues in adolescents is impairment in emotion regulation.^{Reference Pat-Horenczyk, Cohen, Ziv, Achituv, Asulin-Peretz and Blanchard7} Emotion regulation is the ability to recognise, assess, modify and manage emotions in a socially acceptable way in order to gain and maintain control over strong emotions and acquire adaptive functioning.^{Reference Paulus, Ohmann, Möhler, Plener and Popow8} Emotional dysregulation, on the other hand, refers to the maladaptive processing of stimuli, external and/or internal, when emotion regulation strategies are impaired.^{Reference Paulus, Ohmann, Möhler, Plener and Popow8} Emotional dysregulation is mainly characterised by hyperarousal, mood instability, irritability, aggression and maladaptive coping behaviours. Individuals who experience emotional dysregulation during adolescence are more likely to be diagnosed with anxiety disorders, mood disorders and disruptive behaviour disorders in adult life.^{Reference Althoff, Verhulst, Rettew, Hudziak and van der Ende9} Adolescents experiencing high levels of emotional dysregulation have also been found to have elevated rates of self-harm and suicidal behaviour.^{Reference Chesney, Goodwin and Fazel10} One example in this regard is adolescents with emerging borderline personality disorder (BPD). Theories on the development of BPD emphasise that problems with emotion regulation are a core underlying feature of BPD.^{Reference Crowell, Beauchaine and Linehan11} The urgent development of programmes aimed at early intervention in emotional dysregulation is therefore crucial for the prevention of severe and persistent mental disorders in the future.^{Reference Winsper, Marwaha, Lereya, Thompson, Eyden and Singh12}

Dialectical behaviour therapy (DBT) is an evidence-based structured intervention originally developed for adults with emotion and behaviour dysregulation and later adapted for adolescents.^{Reference Miller, Rathus and Linehan13} It emphasises the ability to effectively manage conflicting and intense emotions. DBT is also effective in increasing coping skills across transdiagnostic populations, including those with anxiety disorders and mood disorders.^{Reference Neacsiu, Eberle, Kramer, Wiesmann and Linehan14}

In this paper, we describe a pilot implementation of a DBT group for adolescents attending a busy child and adolescent mental health service (CAMHS) in the state of Qatar. Hamad Medical Corporation (HMC) is the largest public healthcare provider in Qatar, and its specialist CAMHS is a typical community-based multidisciplinary team offering specialised support to children and young people below the age of 18 years with a range of mental and behavioural disorders, and their families.^{Reference Khan, Al-Shamlawi, Phiri and Alabdulla15} The increasing demand for mental health services at HMC CAMHS, with approximately 1300 referrals in 2022 and 1700 in 2023, alongside workforce challenges, highlights the necessity for effective interventions. Group therapies thus present a strategic approach to enhance service delivery.

The aim of this paper is to illustrate how group DBT can offer suitable support for patients while also optimising resource utilisation in mental health services. The process of this pilot project, one of its kind in the region, along with its impact on young people and their families and future directions are also discussed. To our knowledge, this is the first programme of its kind in the Middle Eastern and North Africa (MENA) region. Since this service evaluation initiative did not involve gathering any new data or recruitment of participants, and was instead a retrospective review of feedback questionnaires, the local Institutional Review Board (IRB) did not deem it necessary to require formal approval. However, departmental approval was obtained to publish relevant data, as advised by the IRB. Consent to publish the direct quotes was not required as the data were all anonymised with no information to identify patients.

Impact on service delivery and patient satisfaction

The flexible nature of the group sessions, with variable durations and accommodating external factors, such as the COVID-19 pandemic and holidays, has helped with adapting to the evolving needs of our patient population. This adaptability ensures that the therapeutic intervention remains relevant and accessible despite external challenges. The participating adolescents were asked to complete a feedback form at the end of the course of the group intervention (Supplementary Appendix A, available at https://doi.org/10.1192/bji.2024.18). They were mainly asked to rate the usefulness of the group and whether there had been an improvement in their quality of life since the commencement of the group therapy.

A total of 198 responses were received from the participating 15 adolescents for the sessions attended. All responses except 8 (96%) rated the group sessions as either ‘excellent’, ‘very useful’ or ‘useful’ (Fig. 1). Concerning whether there had been an improvement in the quality of life since attending the group sessions, 174 responses out of the total 198 (88%) reported either significant, moderate or slight improvement (Fig. 2). Qualitative feedback data collected from the young people further substantiated the positive impact of group DBT (Box 1). This feedback has been instrumental in understanding the unique experiences and perspectives of the participants.

Box 1 Qualitative feedback from the 15 adolescent participants in group dialectical behaviour therapy

• • ‘The group is helpful for people who have less belief in themselves, like me’

• • ‘I enjoyed interacting with people and being kind to them while I talked. I liked the role play and the activities’

• • ‘All of the activity skills were fun, I found FAST, GIVE, WHAT, and HOW skills very useful’

• • ‘It is so nice and calm to come here’

• • ‘I use the mindfulness strategies in my class and at home, it has been so helpful’

• • ‘Having my own personal self-soothing kit at home and school has helped me better’

• • ‘I have started my scrapbook and my reading, it has helped me Distract’

• • ‘This skills group has been so useful for all of us and we know we can share experiences here and not feel alone’

Specific instances of positive feedback shown in Box 1 highlight improved coping mechanisms, increased emotion regulation and strengthened interpersonal skills reported by participants. The sense of community fostered in group sessions was particularly praised, with participants expressing a feeling of shared understanding and support. In addition to the feedback provided by the participating adolescents, the improvement in the participants’ well-being and therapeutic progress was further supported by the accounts of their parents and treating psychologists, providing objective evidence of the intervention's usefulness.
