Just as psychotherapists and coaches don’t always see eye to eye, and have some misunderstandings about one another’s disciplines, the same is true for group psychotherapy and team coaching. As a group psychotherapist and a team coach, I have respect for both disciplines. Here’s my understanding of the similarities and differences between the two approaches:

Differences

Group Psychotherapy is a clinical treatment for mental health disorders, although it may be of use to people who are just wanting to invest in their personal development. Team Coaching works best with people that are already high functioning.
Group Psychotherapy is focused on helping each member feel better and reach their individual goals. Team Coaching helps the team as a whole work together better to achieve the organization’s goals.
Group Psychotherapy typically uses the same method or procedure at each session. Team Coaching can use a variety of methods as the work progresses to better help the group.

Both Group Psychotherapy and Team Coaching Require:

A willingness to change

Honesty and transparency, and the co-creation of a trustworthy environment.
A willingness to address difficult issues.
A willingness to become more aware of one’s self and treat others with respect.
