'I Can't Get No Satisfaction'… Experience in the treatment, satisfaction, and professional support of young depressed people using SPARX

Aim: Depression in young people is common and can lead to poor long-term outcomes. Digital therapies are a promising means of promoting access to care. Currently, among the digital treatments for depression in adolescents recognized by the NICE guidelines, there is SPARX (Smart, Positive, Active, Realistic, X-factor), based on Cognitive Behavioral Therapy, CBT. This narrative review aimed to evaluate: 1) Who were the depressed young people who used SPARX and what was their experience with the treatment? 2) Were users satisfied with the SPARX treatment? Did the youth's perceived level of satisfaction with using SPARX impact completion rates? 3) What was the role of professionals (researchers, consultants, teachers) in the SPARX studies? Has their support in running SPARX affected completion rates? Methods: A narrative review of the English literature was performed. The articles were searched in Pubmed, SCOPUS, and Web of Science databases (from 2012 to 2023) with keywords such as 'SPARX,' depression' and 'young adult'. Results: Of 557 papers, 18 were included in our review. The young people who used SPARX were students or adolescents from special help-seeker populations at risk or with mild to moderate depression. The highest satisfaction levels were present in users of primary health services, such as general practice and counseling services. The support of the school counselor and experts in mental health clinicians was instrumental in impacting user satisfaction and completion rates. The personalization of the game in terms of user culture - symbols, language, norms, values, and artifacts; the customization of the avatar, the gender identity; the narrative structure; the presence of a guide character (virtual therapist); the CBT homework seemed to represent crucial SPARX characteristics related to satisfaction and completion rates. Discussion and conclusions: Our narrative review provides an overview of the main results of using SPARX with interesting considerations that may suggest improvements for broader use and diffusion of this digital treatment.
