Wellness coaching and health-related quality of life

Jyothi Menon, Purdue University

Abstract

The objectives for this study were to assess association between completion of any wellness coaching program and changes in health-related quality of life over one year and over two years, and to assess cumulative effects of completion of multiple wellness coaching programs and changes in health-related quality of life over one year and over two years. The data sources for this study were obtained from a health risk assessment file, eligibility files and individual health plan enrollment data for a private insurance plan cohort. The sample inclusion criteria for analysis of the one-year effect of coaching was completion of health risk assessments in two adjacent years and individuals who completed coaching in the baseline year without having completed coaching in the prior year comprised the coaching group. They were matched to individuals who hadn't completed wellness coaching in either of the two years. For analysis of the two-year effect of coaching, individuals who completed wellness coaching in the baseline year and completed health risk assessments two years later were included. Those who hadn't completed wellness coaching in the baseline year or the following year were matched to cases for analysis. Sample exclusion criteria were missing at least one SF-8 score, being pregnant, or reporting presence or absence of diseases in the baseline year which differed after one year for the one-year analysis or that differed after two years for the two-year analysis. Analysis of Covariance and Markov chain model were employed to analyze change in health-related quality of life scores. ANCOVA results for cumulative effects on specific coaching programs showed that individuals who participated in nutrition wellness coaching were more likely to have increased mental component summary scores one year later than those individuals who did not participate in coaching (difference in adjusted means=1.018, P value=0.018,). ANCOVA results also showed that individuals who participated in stress management coaching were less likely to have increases in mental component summary scores over one year (P value=0.007, difference in adjusted means= -1.828) and two years (P value<0.001, difference in adjusted means= -1.952) and less likely to have increases in physical component summary scores over two years (P value=0.037, difference in adjusted means= -0.956) than those individuals who did not participate. Results from Markov chain models on individual domains showed that individuals who participated in any coaching were more likely to have higher social functioning scores over one year (change in cumulative log odds ratio=0.17, P value= 0.027) and less likely to have higher role physical scores over two years than individuals who did not participate in any coaching.
