Schizophrenic patients' deficit in theory of mind impairs their daily interactions with others. An example of a disrupted interaction is one between a schizophrenic parent and a child. Theory of mind is particularly important for parents, who must understand the thoughts and behaviors of their children and react accordingly. Dysfunctional parenting is associated with deficits in the first-order theory of mind, the ability to understand another person's thoughts, and the second-order theory of mind, the ability to infer what one person thinks about another person's thoughts. Compared with healthy mothers, mothers with schizophrenia are found to be more remote, quiet, self-absorbed, insensitive, unresponsive, and to have fewer satisfying interactions with their children. They also tend to misinterpret their children's emotional cues, and often misunderstand neutral faces as negative. Activities such as role-playing and individual or group-based sessions are effective interventions that help the parents improve on perspective-taking and theory of mind. Although there is a strong association between theory of mind deficit and parental role dysfunction, future studies could strengthen the relationship by possibly establishing a causal role of theory of mind on parenting abilities.
