Third-wave approaches to the therapy:

A) are often referred to as the last resort when other therapies fail to work.
B) are entirely based on practices derived from Western philosophy.
C) view unconscious conflicts as the core of many types of psychopathology.
D) combine behavioral and cognitive therapy with the mindfulness practices of Zen Buddhism.

Third-wave approaches to therapy combine cognitive and behavioral therapy with the mindfulness practices derived from Zen Buddhism. They seek to integrate the mind, body, and spirit, and focus on increasing self-awareness and acceptance. They are not considered a last resort, and they do not necessarily view unconscious conflicts as the core of psychopathology. While some third-wave approaches may have roots in Western philosophy, they are not entirely based on it.
