In behavioral health, where staff burnout and turnover are rampant, this guesswork is a high-stakes gamble. A recent National Council survey found that 93% of behavioral health workers have experienced burnout. Hiring based on gut feelings alone isn't enough. Pre-employment personality assessments offer a structured way to measure work-relevant traits, but they are not a silver bullet. They must supplement—not replace—interviews, skills checks, and references.
This guide will walk you through the science, the common models, the legal safeguards, and a practical approach for using personality assessments to build more stable, effective teams in behavioral health.
Key Takeaways
- Personality assessments add structured insight to hiring, but only when measured traits are clearly linked to job requirements.
- Choose tools based on scientific evidence of validity and fairness for your specific use, not just popularity or buzz.
- Use assessment results as one data point to inform a consistent, human-centered hiring process.
- For behavioral health employers, connect assessment decisions to staff stability and care quality without reducing candidates to a score.
What Is a Pre-Employment Personality Assessment?
A pre-employment personality assessment is a standardized tool used to estimate a person's typical patterns of behavior, thought, and emotional response. Clear boundaries matter: these tools estimate traits, not every dimension of job fit.
They measure personality traits, which are enduring characteristics, not:
- Cognitive ability: Problem-solving or learning capacity.
- Technical skills: Proficiencies acquired through practice.
- Interests: What a person enjoys doing.
- Clinical diagnoses: These are not mental health evaluations.
Assessments use standardized questions and scoring to estimate work-related tendencies like conscientiousness, emotional stability, or interpersonal style. They generally fall into two categories:
- Trait-based assessments: Measure characteristics on a continuum (for example, how conscientious someone is).
- Type-based assessments: Place individuals into distinct categories or profiles (such as labeling someone an "Innovator").
Employers use the results to inform selection, plan interviews, guide team composition, and create development plans. A test result is only an indicator of likely preferences, not a guarantee of future performance or compassionate care.
The foundation of any defensible assessment program is a job analysis: a formal process to identify the behaviors and outcomes required for success in a given role.
Why Employers Use Personality Assessments in Hiring
When multiple candidates have similar resumes and interview well, how do you make a consistent, informed choice? Structured assessment data can provide an objective layer of insight that gut feelings cannot.
For behavioral health organizations, the stakes are particularly high. The right assessment can help you evaluate attributes critical to patient care and team stability, including:
- Dependability and follow-through
- Emotional regulation under stress
- Interpersonal sensitivity and boundary awareness
- Teamwork and collaboration
- Response to constructive feedback
Research shows a connection between certain personality traits and work outcomes. For example, conscientiousness is a consistent, though modest, predictor of job performance across many roles.
A 2022 meta-synthesis found job-performance correlations of 0.20 for conscientiousness and -0.15 for neuroticism. This shows an association, not a guarantee.
When used responsibly, these insights don't stop at the hiring decision. They can inform onboarding, improve manager communication, and guide professional development long after the offer letter is signed.
A word of caution: Avoid using assessments to hire for "culture fit," which often becomes a proxy for hiring people who look, think, and act like the existing team. Instead, focus on evaluating a candidate's alignment with explicit, inclusive, and well-defined workplace behaviors.
Common Employment Personality Assessments and What They Measure
Many personality tools are available, but not all are built or validated for pre-employment screening. Knowing which ones belong in hiring protects your process.
Big Five or Five-Factor Model (FFM)
This is a widely accepted scientific framework that measures personality across five dimensions:
- Openness: Curiosity and creativity.
- Conscientiousness: Organization and dependability.
- Extraversion: Sociability and assertiveness.
- Agreeableness: Cooperation and compassion.
- Neuroticism (or Emotional Stability): Resilience and stress tolerance.
Because the Big Five is a dimensional model based on decades of academic research, it's often viewed as a more scientifically robust foundation for assessments used in hiring.
Hogan Assessments
The Hogan suite is designed specifically for workplace applications and distinguishes between three perspectives:
- HPI (Hogan Personality Inventory): Measures "bright-side" personality: how we behave at our best.
- HDS (Hogan Development Survey): Identifies "dark-side" traits (potential derailers that emerge under pressure).
- MVPI (Motives, Values, Preferences Inventory): Explores a person's core values and drivers.
Hogan's focus on job performance and its extensive validation research make it a common choice for selection and development.
DiSC
The DiSC model categorizes behavioral styles into four types: Dominance, Influence, Steadiness, and Conscientiousness. It's a popular tool for improving team communication and self-awareness. However, its publisher, Wiley, has an official policy that explicitly prohibits using Everything DiSC for hiring or selection. It is designed as a development tool, not a predictive hiring instrument.
Myers-Briggs Type Indicator (MBTI)
The MBTI is the best-known personality tool, assigning individuals to one of 16 four-letter types (e.g., INTJ, ESFP). It's widely used for personal development and team-building exercises. However, the publisher of the MBTI explicitly states it should not be used for hiring or job placement. Critics point to psychometric limitations, including test-retest reliability, that make it unsuitable for selection decisions.
CliftonStrengths (formerly StrengthsFinder)
This tool identifies an individual's top "talent themes" from a list of 34, with the goal of helping people focus on their strengths. Like the MBTI and DiSC, it is a powerful development resource. But Gallup, its publisher, is clear: CliftonStrengths should not be used for hiring or comparing candidates. Knowing someone's strengths doesn't predict their performance in a specific job.
How to Choose a Defensible Assessment for Pre-Employment Use
Selecting an assessment requires a rigorous, defensible process grounded in science and law, not a popular brand name.
Start with a Job Analysis: Before you even look at a test, you must identify the essential tasks, behaviors, and measurable outcomes for the role. This analysis is the bedrock of a legally defensible hiring process.
Evaluate Scientific Evidence: Ask for the technical manual. Look for data on the tool's:
- Validity: Does the test measure what it claims to measure, and does it predict job performance?
- Reliability: Does the test produce consistent results over time?
- Norm Group: Was the test validated on a population relevant to your candidates and workforce?
Confirm Its Purpose: Ensure the assessment was designed and validated for employment selection, not just for entertainment, self-reflection, or team-building.
Examine Fairness and Accessibility: Research how the vendor monitors for bias and adverse impact against protected groups. Confirm the assessment is accessible and that there is a clear process for requesting accommodations under the Americans with Disabilities Act (ADA).
Review Data and Privacy Practices: Understand how candidate data is collected, stored, and used. In the US, laws like the California Privacy Rights Act (CPRA) are setting new standards for employee data.
Under the Uniform Guidelines on Employee Selection Procedures (UGESP), the employer, not the vendor, is ultimately responsible for ensuring an assessment is valid for its specific purpose. Always consult with qualified employment counsel before implementing any new selection tool.
How to Use Personality Assessments in a Fair Hiring Process
A powerful tool used improperly can do more harm than good. A fair process is consistent, transparent, and human-centered.
- Create a Consistent Workflow: Document when the assessment is given, who reviews results, and how scores are weighted with interviews and skills tests. Apply the same process to every candidate for that role.
- Be Transparent with Candidates: Tell candidates why you're using the assessment, how long it takes, how results will be used, and how to request an accommodation.
- Train Your Hiring Managers: Train managers to read results cautiously, avoid stereotypes, and treat the assessment as one input—not a final verdict.
- Generate Structured Interview Questions: Turn results into behavior-based follow-ups. If a report flags conflict avoidance, ask: "Tell me about a time you had a professional disagreement with a colleague. How did you handle it?"
- Monitor Outcomes: Review hiring data for adverse impact on a set cadence. If the tool stops yielding useful, fair, job-related signal, revise the process or stop using it.
Applying Assessment Insights After the Hire
The value of a good assessment doesn't end once a hiring decision is made. For behavioral health organizations focused on retention, the insights gained can be a roadmap for supporting new employees.
Results can inform:
- Role-specific onboarding
- Manager check-ins
- Personalized development plans
That support matters in an industry where turnover can approach 30-40% annually. Connecting a new hire's behavioral profile to coaching can mean the difference between someone who thrives and someone who burns out.
At Care Predictor, we've seen this impact firsthand. Our platform was founded on the belief that the quality of behavioral healthcare depends on the people delivering it. We use behavioral science and data analytics to provide clarity before the hire, through onboarding, and across the employment lifecycle.
Our internal data from a two-year study covering over 7,300 treatment episodes showed that therapists who scored highly on the Care Profile assessment:
- Completed 25% more treatments
- Lost 29% fewer patients to AMA (Against Medical Advice)
Another analysis at Alter Behavioral Health linked the process to a 32% improvement in treatment completion and over $4.3 million in care-driven revenue growth.
The Care Predictor platform is a workforce intelligence tool built for behavioral health. It pairs a validated pre-hire assessment with interviewing guides and post-hire engagement tools so organizations can build teams that deliver better care and outcomes.
Frequently Asked Questions
Can you use personality tests for hiring?
Yes, employers can use appropriately validated, job-related assessments as one part of a broader selection process. They must be administered in compliance with all applicable US employment, accessibility, privacy, and anti-discrimination laws.
What employment personality assessments are commonly used in recruitment?
The Big Five, Hogan, DiSC, MBTI, and CliftonStrengths are all common. However, popularity does not equal suitability, and several of these (DiSC, MBTI, CliftonStrengths) are not intended or validated for hiring decisions.
What personality traits do employers look for?
This depends entirely on the job analysis for a specific role. Common desirable traits include conscientiousness, dependability, emotional stability, collaboration, and adaptability, but there is no single ideal personality.
What is an employment personality assessment?
It is a standardized tool that estimates work-related behavioral tendencies. It is not a clinical diagnosis, a measure of intelligence, or a complete prediction of an individual's future job performance.
What is the Big 5 personality test for employers?
This refers to an assessment based on the five-factor model (Openness, Conscientiousness, Extraversion, Agreeableness, Neuroticism). Employers should only use a version with documented reliability, validity, and evidence of fairness for employment selection.
What are the four main personality types of employees?
There is no universally accepted set of four employee personality types. Frameworks like DiSC use four categories, but these are specific to that model and should not be confused with scientifically established universal classifications.
