ABSTRACT
As we have seen, ACT seeks to increase people's willingness to experience even the most undesirable thoughts, emotions, and sensations as part of pursuing valued behavioural directions. Hence, it is essential that clients are able to access a psychological perspective, or sense of self, from which dif®cult psychological content appears less threatening. In ACT, this transcendent sense of self is variously referred to as ``self-as-context'', the ``observing self'', or ``self-as-perspective'', and represents a core therapeutic process (Hayes et al., 1999).
