Many clients have benefited enormously, suffering transformed into healthy functioning. Unfortunately, progress is often limited with approximately one-third drop-out rates an indicator, and for the two-thirds of clients that persist with psychotherapy, less than ideal outcomes are fairly common. Hence, an exploration of factors impeding the progress of psychotherapy, and application of robust strategies to reduce drop-out rates and enhance outcomes is required.
