Attitudinal organizational commitment and job performance: a meta‐analysis

A meta‐analysis was conducted to estimate the true correlation between attitudinal organizational commitment and job performance and to identify moderators of this correlation. One‐hundred and eleven samples from 93 published studies were included. The corrected mean correlation was 0.20. The correlation was at least marginally significantly stronger for: (a) extra‐role performance as opposed to in‐role performance; (b) white‐collar workers as opposed to blue‐collar workers; and (c) performance assessed by self ratings as opposed to supervisor ratings or objective indicators. Four other assumed moderators (commitment measure: Affective Commitment Scale versus Organizational Commitment Questionnaire, job level, age, and tenure) did not have at least marginally significant effects.
