Theoretical studies of singleness span a variety of disciplinary fields, and there are existing studies in sociology and psychology that discuss the theoretical explanations behind singleness and reveal the reasons for singleness as well as the related influencing factors. Based on the existing literature, we review the current theories of singleness in psychological research, including social exchange theory, symbolic interaction theory, developmental task theory, and attachment theory, to help understand the complexity and diversity of the singleness phenomenon, and to emphasize the adoption of targeted measures for individuals with different types of singleness in order to promote the harmonious development of society, as well as the enhancement of psychological well-being.展开更多
