Psychoeducation is a vital component of the clinical approach to managing bipolar disorder, often incorporated as part of a broader psychosocial intervention. Several aspects of bipolar disorder underscore the significance of psychoeducation as a key intervention. These include high levels of medication nonadherence among patients, the crucial role of the therapeutic alliance, and the impact of lifestyle habits on the risk of relapse. This chapter seeks to outline the essential components of psychoeducation, synthesise the existing evidence base supporting its efficacy in managing bipolar disorder, and explore practical considerations for its implementation. Additionally, it aims to identify avenues for further research that could enhance the adoption and effectiveness of psychoeducation in the management of bipolar disorder.
