Abstract: This article synthesizes meta-analytic evidence on psychologically informed coaching approaches to identify mechanisms driving sustained workplace outcomes. Drawing on Wang et al.'s (2021) comprehensive meta-analysis of 20 studies (n = 957), we examine how cognitive behavioral coaching, solution-focused coaching, positive psychology coaching, and integrative approaches influence goal attainment, self-efficacy, performance, and psychological well-being. Findings demonstrate moderate to large positive effects across outcomes (g = 0.51), with goal attainment showing the strongest impact (g = 1.29) and self-efficacy showing substantial gains (g = 0.59). Integrative approaches combining multiple psychological frameworks generated larger effects (g = 0.71) than single-method interventions (g = 0.45). For practitioners, evidence supports designing coaching that blends cognitive coping strategies, strength-based techniques, and contextual sensitivity to address individual values, organizational dynamics, and systemic resources for sustainable development.
