Collaborations among researchers, clinicians, and persons with mental illness from high-income countries (HIC) and low- and middle-income countries (LMIC) are crucial to produce research, interventions, and policies that are relevant, feasible, and ethical. However, historically global mental health and cultural psychiatry research publications have been dominated by HIC investigators. This paper presents recommendations for collaborative writing between HIC and LMIC researchers with a special focus on early career researchers in HIC and LMIC. A step-by-step process for collaborative manuscript writing highlighting issues especially important for global health and global mental health research is provided. High-income countries and LMIC writing collaborations will encourage accurate, ethical, and contextually-grounded publications to foster understanding and facilitate reduction of the global burden of mental illness.
