Abstract

Psychological assessment has long been reported as a key component of clinical psychology. This paper examined and shed light on the complexities surrounding the clinical significance of therapeutic approach to treatment Planning. To achieve this objective, the paper searched and used the PsycINFO and PubMed databases and the reference sections of chapters and journal articles to analysed the underlying themes: 1) a strong basis for the usage of therapeutic approach to psychological assessment in treatment plans, 2) explained the conceptual meaning of clinical significant change in therapeutic assessment, 3) used initial theory to explain the therapeutic mechanisms of change in clinical practice, 4) analysed the empirically documenting clinically significant change in therapeutic assessment. Finally, the study suggested that though therapeutic assessment is not sufficient for the systematic study of psychotherapy outcome and process, it is still consistent with both the lay-man and professional expectations regarding treatment outcome and also provides a precise method for classifying clients as “changed” or “unchanged” on the basis of clinical significance criteria.
