There exists a gap between the field of clinical psychology and the concepts and practice of astrology. The validity of the use of astrological interpretations of personality is not accepted in mainstream psychology despite the fact that psychology can trace its origins back to astrological principles that precede it by thousands of years. Both the psychological and mainstream communities have relied for decades on the Myers-Briggs Type Index and more recently on the Five Factor Model for standardized personality measurement. This study seeks to illuminate the value of astrology as a description of personality and lessen the divide between the two disciplines of astrology and psychology. Based on similarly structured research on the recognition of self in personality profiles using the MBTI, Lennox and Oleson expanded this model into the controversial realm of astrology. Clinicians and laypersons alike will find compelling evidence for the legitimacy of this ancient practice in our modern world.
