Bipolar disorder (BD) is a severe mental health disorder with mood swings and activation. Youths at risk of BD need treatment to prevent the syndromes from worsening and developing. Among the mass treatment approaches. The psychosocial treatment method of family-focused treatment (FFT) gradually proved to be a good way of helping youths at risk of BD. The researcher reviewed the literature and searched and screened related articles in the past 11 years. As a result, a clear path of development for FFT in treating youths with BD is found, with four stages identified: the beginning, the transition, the development, and the new development. Moreover, it is suggested that in future research, more investigation under comorbid disorders can be analyzed, and researchers can continue to modify the experimental design of comparison between FFT and enhanced care to increase the research's validity. Additionally, technology can be used to better assist FFT in treating youths at risk for BD.
