Effectiveness of online cognitive behavioural therapy on quality of life in adults with depression: A systematic review.

Accessible Summary: What is known on the subject: Depression is a leading cause of disability worldwide that negatively impacts quality of life. Talk therapy such as cognitive behavioural therapy is an effective treatment for depression. The Internet is an important tool for mental healthcare delivery. Internet‐delivered or online talk therapy interventions are associated with lower costs and improved accessibility.Current reviews do not address the effectiveness of Internet‐delivered cognitive behavioural therapy (iCBT) on quality of life (QoL). What the paper adds to existing knowledge: Interventions for iCBT have better QoL improvements for individuals with greater depressive symptom severity, females, young adults and individuals with complex comorbid disorders. Support from a healthcare provider for iCBT interventions have better outcomes than self‐guided therapy interventions. Tailoring the iCBT intervention to the specialized needs of the population is beneficial. What are the implications for practice: There is potential to address treatment gaps for managing the care of individuals with depression. Utilizing iCBT promotes the integration of accessible mental healthcare in clinical settings.Healthcare providers can have a more comprehensive approach to delivering iCBT by considering adaptations relevant to the clinical population being treated. Introduction: Major depressive disorder (MDD) is a leading cause of disability resulting from social, psychological and biological factors affecting quality of life (QoL). Cognitive behavioural therapy (CBT) is an effective psychotherapy for MDD. Internet‐delivered CBT (iCBT) is associated with lower costs and improved accessibility. Aim: We aimed to examine the effectiveness of iCBT on QoL in adults with depression. Method: PubMed, Embase and PsycINFO were searched between 2010 and 2022. Inclusion criteria were experimental designs, adults ≥18 years old, depression diagnosis or valid self‐report measure, iCBT intervention; and QoL outcome. Exclusion criteria were studies without depression analysis and intellectual disabilities or psychosis. Results: Seventeen articles were included, with a negative correlation between depression severity and QoL. Sex, age and physical comorbidity positively influenced effectiveness. Depressive severity, dysfunctional attitude and negative thinking were predictors and moderators of QoL. Clinician support can impact social interactions and sense of belonging. Discussion: Internet‐delivered cognitive behavioural therapy is effective for improving QoL in adults with MDD. Severe depression, females, younger age and comorbid disorders were associated with greater QoL improvements. Implications for Practice: The findings suggest iCBT could address depression treatment gaps related to improving QoL. Utilizing iCBT potentially improves the care continuum for individuals with complex disorders. [ABSTRACT FROM AUTHOR]
