Final answer:
The MMPI, a self-report inventory with 10 clinical scales and 4 validity scales, is used to create a clinical profile through true/false questions, for various purposes including occupational screening.
Step-by-step explanation:
The psychological assessment tool that features 10 clinical scales and 4 validity scales is the Minnesota Multiphasic Personality Inventory (MMPI). This self-report inventory is designed to create a clinical profile of an individual through a series of true/false questions. Among its scales, you will find the hypochondriasis, depression, hysteria, psychopathic deviance, masculinity vs. femininity, paranoia, psychasthenia, schizophrenia, hypomania, and social introversion. The MMPI is not only used for clinical diagnosis but also for occupational screening and in counseling environments. Additionally, it is important to note that the MMPI is distinct from projective tests like the Rorschach Inkblot Test, as the MMPI provides a more objective measure of personality.
