Final answer:
Self-report personality measures are labeled as such because they depend on individuals' self-assessment, but responses can be biased, affecting their validity. Myers-Briggs Type Indicator (MBTI) and Minnesota Multiphasic Personality Inventory (MMPI) are examples of such measures which commonly use Likert scales.
Step-by-step explanation:
Self-report personality measures are termed so because they rely on individuals' self-assessment of their personality traits. These instruments, such as the Myers-Briggs Type Indicator (MBTI) and the Minnesota Multiphasic Personality Inventory (MMPI), typically use Likert scales where participants indicate their agreement with statements on a scale, often ranging from 1 (strongly disagree) to 5 (strongly agree). The degree of objectivity in responses can be compromised as individuals may present themselves in a socially desirable manner, or may lack self-awareness, leading to biased responses that can affect the validity of the personality test. This is particularly relevant in high-stakes situations like job applications or clinical assessments, where the pressure to appear favorable could be higher. Despite these limitations, self-report inventories remain a popular and cost-effective method for personality assessment in various contexts, including employment screening and psychological diagnostics.
