Some aspects of a health coach's performance are easier to assess than others, says Darcy Hurlbert, health and wellness product specialist at Ceridian LifeWorks. Employees themselves can provide valuable data on the effect of coaching on workforce productivity and absenteeism, she says, and this can be supplemented with administrative data. Satisfaction surveys administered three months post-enrollment can capture employee and member feedback on the coaching experience. Hurlbert, along with Ted Borgstadt, TrestleTree founder and chairman, described the types of metrics that can and should be used when evaluating the effectiveness of both health coaching programs and individual health coaches during a November 15, 2007 webinar, Health Coaching ROI Metrics and Measurements.
