This self-report measure is designed to assess discretionary work behaviors that extend beyond formal job requirements. The Extra-Role Work Behavior Scale provides a brief snapshot of how often an employee reports engaging in behaviors that support effectiveness beyond assigned duties.
The instrument, attributed to J. P. Campbell, includes 12 items and typically requires about 3 minutes to complete. Items focus on common domains of extra-role contribution, such as efforts to improve work performance, willingness to contribute additional time, and supportive behavior toward coworkers.
In applied settings, the Extra-Role Work Behavior Scale may be used to complement broader assessments of work behavior by characterizing patterns of initiative and cooperative engagement. Results should be interpreted in context (e.g., role expectations, work demands, and organizational norms) and are not intended to serve as a standalone indicator of overall job performance.
