Final answer:
Objective information can be collected through physical examinations and standardized tests like the MMPI, which are based on observable and measurable facts. Projective tests, family interviews, and personal journals tend to collect subjective information.
Step-by-step explanation:
Assessments that can be performed on a client in order to collect objective information include physical examinations. Unlike subjective assessments, which rely on personal feelings or opinions, objective information is based on observable and measurable facts. Physical examinations are done by healthcare professionals to observe and measure various aspects of a client's health status, such as checking vital signs, performing laboratory tests, and other diagnostic procedures.
Some psychological assessments aim to collect objective information as well. For example, the Minnesota Multiphasic Personality Inventory (MMPI) is a standardized psychometric test of adult personality and psychopathology used to assist with the diagnosis of mental disorders. It is designed to provide an objective measure of psychological states.
Projective tests, on the other hand, are more subjective in nature. Similarly, subjective information may be gathered through methods like interviews with family members, reviewing personal journals, or using self-report measures such as the Myers-Briggs Type Indicator (MBTI), which reflects personal preferences.
