What defense mechanism is exhibited by a client who states, "I missed my appointment because I overslept, but I knew it would be pointless anyway"?

The client’s statement reflects rationalization, which is a defense mechanism where a person justifies or explains an action or feeling with logical reasons, even if those reasons are not the true motivations. In this case, the client missed their appointment but attempts to protect their self-esteem by saying that it would have been pointless anyway. This reasoning serves to reduce feelings of guilt or failure associated with missing the appointment.

Rationalization allows the client to maintain a sense of control and coherence in their thought process, even when their actions may not align with desired outcomes. By framing the missed appointment as pointless, the individual deflects responsibility and tries to make sense of their behavior, rather than confronting any possible anxiety or shame regarding the missed commitment. This coping strategy can shield the individual from the emotional discomfort associated with taking responsibility for their choices.
