What are the differences between self-report and behavioral personality assessments for hiring?

Understanding the distinction between self-report and behavioral personality assessments is crucial for optimizing your selection process. Each type offers unique advantages and potential drawbacks.

**Self-report assessments** are what most people envision when they hear 'personality test.' Candidates answer questions about their own traits, preferences, and typical behaviors (e.g., 'I am often the life of the party,' 'I pay attention to details'). These are generally time-efficient, cost-effective, and provide direct insights into a candidate's self-perception. However, a primary concern with self-report measures is response distortion, or 'faking good,' where candidates might try to present themselves in the most favorable light. While most robust self-report tests include validity scales to detect such attempts, it remains a consideration. Buyers frequently ask if these tests are truly objective, and the answer is that while they reflect self-perception, their validity lies in how well that self-perception correlates with actual job performance.

**Behavioral assessments**, on the other hand, infer personality traits from a candidate's observed actions or reactions in specific scenarios. These can include situational judgment tests (SJTs), gamified assessments, or simulations where candidates respond to hypothetical work challenges. The key advantage is that they are less susceptible to faking, as candidates' choices in realistic scenarios provide a more objective measure of how they might behave. They also tend to have higher face validity for candidates, as the scenarios often mimic actual job tasks. However, behavioral assessments can be more complex to design, administer, and score, often requiring more development resources. For critical roles, the added validity often outweighs the increased cost and complexity, providing a more robust prediction of on-the-job performance.
