The largest ever coaching outcome research – preliminary findings
Data collection is now completed on this project.
The Ashridge Centre for Coaching is proud to present the Greatest Coaching Outcome Research Project in history, which has already drawn exactly 2,018 completed client questionnaires, 1,880 matching coach questionnaires and 130 matching coaching sponsor questionnaires. These numbers are at least ten times more than most existing coaching outcome studies and larger than any study that we know of in this field.
A number of articles summarising the findings are currently under peer review.
We have already analysed about 75% of the complete dataset. So far we have found:
- There are substantial correlations between different independent estimates of coaching outcome (between client and coach and between client and sponsor, but not between coach and sponsor)
- The coaching relationship remains the best predictor of outcome
- Client self-efficacy seems an active ingredient as well, as it correlates with coaching outcome, both as rated by the client and as rated by the coach
- Coach self-efficacy does not correlate with client-rated outcome
- Only small correlations between personality in terms of MBTI and the other variables above.
In other words: (1) clients, coaches and sponsors agree on what they see as coaching outcome, (2) the coaching relationship is a very important factor in effectiveness and (3) client self-efficacy (the client’s self-motivation) is an important active ingredient as well.
We expect these findings to be robust, because of the large sample sizes.
