Suboptimal psychological well-being in children can have substantial negative effects on their physical health, academic performance, and lifelong health. Preliminary evidence supports that self-compassion have positive impacts on psychological well-being in elderly, adults, and adolescents, but there is apparently lack of this kind of evidence in children. Involvement of parents in the program potentially optimize the effects, this study thus designs a dyadic parent-child self-compassion program (DPC-SC) and aim to examine its effects on children's psychological well-being.
