There is empirical evidence to support the use of astrology in psychological counseling; reports from empirical studies show evidence of statistically significant correlations between extraversion tendencies and planets in the “positive” signs of the zodiac, (i.e. Aries, Gemini, Leo, Libra, Sagittarius, Aquarius) source: .(Tarvainen, On Astrological Polarity in Extravert/Introvert Groups, Correlation, Vol 32, 1, 2018,p. 33).

Using astrology to facilitate self-understanding and personal growth in my clients is a valuable tool. One study conducted in 2018 found that astrological birth charts could be used as a tool to help clients identify personal strengths and weaknesses and foster self-exploration. (“A Constructivist Investigation of Astrology as a Tool for Self-Discovery”, in New Age of Leadership; Martin, Cameron; University of San Diego, 5/17/2022).
Additionally, I have used astrology in my practice to serve as a useful starting point for therapy sessions by providing insight into my clients personality traits, tendencies, and potential areas of conflict that impact their well-being. (Grove, John, Dreams and Astrological Psychology,2014, Hopewell Publishing. Knutsford, UK) The Huber method in Astrological Psychology is the theory behind this work.
However, I do not use astrology as a stand-alone intervention for mental health concerns of a chronic nature. It should be used in conjunction with evidence-based treatments, such as cognitive behavioral therapy with the use of medication prescribed by a physician. And I do not do astrological prediction of events in the lives of my clients.
I am consulted frequently by clients who want to identify traits of personality in identity formation throughout the life cycle of development.
The use of sub-personalities in psychotherapy is a necessary ingredient to developing a mature self-identity. Certain aspect patterns in Astrological Psychology support and identify these subpersonalities which show differing motivations. (Huber, Bruno and Louise, Aspect Pattern Astrology, Hopewell, Knutsford, UK, 2005).

Below is research evidence of the existence of the concept of sub-personalities in humans:
1, Neuroimaging studies have shown that different parts of the brain are activated when individuals describe different aspects of their personality and emotions. For example, one study showed different patterns of brain activity when participants were asked to think about their inner child vs. their critical voice. (Frontiers in Psychology, 2017 volume 8, p. 1432 “Basic emotions in Human Neuroscience: Neuroimaging and Beyond”. authors; Celeghin, DIAMO, BAGMIS, Viola, Tamietto)
2. Case studies and clinical experience: I have documented cases (with substantial support of colleagues in my field), where individuals report experiencing different states of being or multiple personalities, ego states, indicating that they have distinct sub-personalities. (Grove, John, Life Passages: When Dreams and Age Points coincide; p. 39; Hopewell Publishing, Knutsford, UK. 2017, p. 39).
3. Outcome studies from Gestalt therapy and Internal Family Systems (IFS): both treatment modalities have documented excellent treatment outcomes related to addressing inner conflicts, reducing anxiety, and fostering self-awareness and growth.
While the concept of sub-personalities within the theoretical framework of Psychosynthesis is not widely researched it remains an essential concept withing\ many psychotherapy modalities. Therapists practicing IFS for instance, report that when sub-personalities are identified, personified and dialogued with directly, it can help individuals resolve inner conflicts and boost healing. (Richard Swartz and internal family systems, Internal Family Systems, New York, NY, Guilford Press 1997).

Although most scientists and psychologists view astrology through a skeptical lens, there is substantial reporting from my clinical experience that it is vital for understanding psychological traits and motivations that are unconscious in the client. And furthermore this work offers insight into conflicting intrapersonal issues facing those seeking self-knowledge.
