The literature on interventions like UP is non-existent. The closest approximation might be on executive coaching, startup accelerators, detox programs, military bootcamps or graduate school degree programs. A few selected papers and reports from the field of coaching are included below. Hundreds more are available upon request.

A meta-analysis on the effects of coaching on individual level outcomes in an organizational context, The Journal of Positive Psychology: Dedicated to furthering research and promoting good practice, DOI: 10.1080/17439760.2013.83749.

Whereas coaching is very popular as a management tool, research on coaching effectiveness is lagging behind. Moreover, the studies on coaching that are currently available have focused on a large variety of processes and outcome measures and generally lack a firm theoretical foundation. With the meta-analysis presented in this article, we aim to shed light on the effectiveness of coaching within an organizational context. We address the question whether coaching has an effect on five both theoretically and practically relevant individual-level outcome categories: performance/skills, well-being, coping, work attitudes, and goal-directed self-regulation. The results show that coaching has significant positive effects on all outcomes with effect sizes ranging from g = 0.43 (coping) to g = 0.74 (goal-directed self-regulation). These findings indicate that coaching is, overall, an effective intervention in organizations.

Coaching and coaching psychology offer a potential platform for an applied positive psychology and for facilitating individual, organisational and social change. Experts from around the world were invited to comment on the emerging discipline of coaching psychology and the commercial coaching industry. Several key themes emerged including the potential of coaching to contribute to health promotion, social change and organisational development. There was unequivocal consensus for the need for an evidence-based approach to coaching. A review of the psychological coaching outcome literature found there have been a total of 69 outcome studies between 1980 and July 2007: 23 case studies, 34 within-subject studies and 12 between-subject studies. Only eight randomised controlled studies have been conducted. This indicates that coaching psychology is still in the early stages of development, and can be understood as an emerging or protoscientific psychological discipline. A languishing-flourishing model of coaching is described. To flourish, coaching psychology needs to remain clearly differentiated from the frequently sensationalistic and pseudoscientific facets of the personal development industry while at the same time engaging in the development of the wider coaching industry.

The popularity of executive coaching has increased dramatically in both the practitioner world and academia during the past decade. However, evaluating the effectiveness of coaching has lagged behind. Executive coaching is a multi-disciplinary practice, and professionals from many different scholarly back-grounds provide coaching services. The paucity of empirical research may be attributed to the lack of a consensus among these divergent professionals regarding whether and how to evaluate the effectiveness of coaching. In this article, we conducted a meta-analysis of the empirical research as well as reviewed the retrospective studies evaluating coaching effectiveness. Subsequently, we discussed six areas that impact the way researchers evaluate coaching effectiveness and the conclusions they may draw from their studies. Although the Return On Investment (ROI) index provides a straightforward, overall measure of effectiveness, its veracity and usefulness is questioned. It is hoped that the clarification of these areas will help guide the future of coaching evaluation research and practice.

Executive coaching, which surfaced as a leadership development practice over a decade ago, is now among the most widely used executive development techniques. Yet, despite its growing tenure as a leadership development practice, executive coaching is still used sparingly in many organizations, and has remained underutilized. The authors believe this is because the paucity of empirical research into its effectiveness leaves the field open to speculation and subjective opinion.

Research and anecdotal evidence suggest that the majority of organisations make no attempt to evaluate their investment in executive coaching services. Although a body of work espousing the value of financial return on investment (ROI) methodologies exists, few organisations appear to have faith in the value of these frameworks in persuading senior management as to the efficacy of coaching. This paper reports the findings of a survey conducted with purchasers of executive coaching services (purchasing clients) using a semi-structured interview. The survey was designed to explore how purchasing clients currently evaluate their investment in coaching. Using a grounded theory approach, a new model for evaluating investment in coaching services is presented. The new model places a primary emphasis on establishing the purpose of coaching, and on establishing an ongoing, formative approach to evaluation. The potential value of the new model to both organisations and executive coaches is discussed.
