Employee engagement differs
from and has a stronger performance-enhancing effect than
other, similar job-related constructs, such as job involvement,
intrinsic motivation, and job satisfaction (Rich et al.
2010). For example, Rich et al. (2010) find that when
controlling for job involvement, job satisfaction, and
intrinsic motivation, employee engagement has a stronger
significant impact on task performance and employee
organization citizenship behavior than the above-mentioned
variables (i.e., job involvement, job satisfaction, and
intrinsic motivation).
