Problem Statement: Studies show that wellness is closely associated with individual life style. Thus, any efforts toward improving wellness should target aspects of a person's life style. A means of assessing holistic wellness is needed to design programs that increase individuals' /clients' health and wellness and to develop psychological counseling approaches. In other words, a valid and reliable measurement instrument is required. Recent years have witnessed the development of a great number of models of wellness and of a variety of measurement instruments. In Turkey, however, there are few studies on this subject.
