Assessment of positive functioning in clinical psychology: theoretical and practical issues.

Positive psychology has led to an increasing emphasis on the promotion of positive functioning in clinical psychology research and practice, raising issues of how to assess the positive in clinical setting. Three key considerations are presented. First, existing clinical measures may already be assessing positive functioning, if positive and negative functioning exist on a single continuum (such as on bipolar dimensions from happiness to depression, and from anxiety to relaxation). Second, specific measures of positive functioning (e.g., eudemonic well-being) could be used in conjunction with existing clinical scales. Third, completely different measures would be needed depending on whether well-being is defined as emotional or medical functioning, or as humanistically orientated growth (e.g., authenticity). It is important that clinical psychologists introduce positive functioning into their research and practice in order to widen their armoury of therapeutic interventions, but in doing so researchers and practitioners need also to be aware that they are shifting the agenda of clinical psychology. As such, progress in clinical psychology moving toward the adoption of positive functioning requires reflection on epistemological foundations.
