Evidence-based methods that are used by Industrial-Organizational Psychologists during recruitment and selection of employees are tests like drug screening and personality-based test. Personality-based measures are designed to measure conscientiousness and socialization for specific roles that may require constant interaction with others such as customers and employee teamwork (Cascio & Aquinis, 2019). These tests are often computer based and often include integrity tests to assess attitudes towards theft and dishonesty that may affect the company. Drug screening measures help employers ensure that candidates are in compliance with their drug-free policies and regulations and are used to enhance workplace safety (Cascio & Aquinis, 2019). Employers often mention in their company's policy what their expectations are for their employees and inform them on what their policy is regarding drug usage
