Abstract
Adolescents and young adults (AYA) face individual and social challenges different to other age groups that shape their experience of cancer and the associated psychological distress. This critical review examined the availability of AYA-specific psychosocial interventions in order to assess the impact they have and identify elements that make them successful. Five literature databases were searched for psychosocial intervention studies involving AYAs with cancer, on and off-treatment, aged 10-30 years, published between 1980 and 2016. Eleven out of 42 identified studies were included in the final review after quality assessment. All but two interventions showed positive results on at least one measure of psychosocial wellbeing. A distinctive difference between the supportive needs of those on and off-treatment was noted, and differences in intervention design and delivery formats were identified between the two sub-groups. Analysis of specific intervention characteristics that achieved the successful outcomes was more challenging due to the large variation in outcome measures used. This review demonstrates that psychosocial intervention research for AYA with cancer is increasing and the results show a potential benefit of intervention participation. Further work is needed to validate whether the benefits achieved by intervention participation remain over time.
