Suicidal ideation and attempt is a major risk factor involved in mental health. It is a global public health concern contributing to 800,000 deaths every year. The efforts and attempts that have been used previously employed to prevent suicide have been risk and deficit oriented. Positive psychology cultivates feelings of positivity, hope, and optimism which hold the potential of reducing potential suicide risk. The positive psychology interventions have been associated with reduced risk of suicidal ideation. This chapter will nurture the emergence of a new field-positive suicidology. Overall, it will provide a scientific framework to address suicidal behaviours and thoughts through a positive approach in order to promote well-being. The chapter will include the interpersonal and intrapersonal risk factors associated with suicide. The protective factors in suicide such as hope, resilience, and optimism will be covered. Cognitive, affective, and behavioural components related to suicide will also be highlighted. It will incorporate the integration of psychological theories of positive psychology such as Broaden and Build Theory and theories of suicidology such as emotional dysregulation. The integration of these theories will lead to better understanding of the implementation of positive psychology interventions in prevention of suicide. The interventions emphasize upon future orientation, gratitude, hope, optimism, forgiveness, and mindfulness which contributes to mental health well-being through a positive as well as strength-based approach. The chapter will also include the contextual factors such as race, ethnicity, and gender in the application of positive psychology approaches to suicide.
