Score Interpretation of WAIS IV and MMPI II
By Inderbir Kaur Sandhu, Ph.D
I'm trying to understand what all these test scores mean, can you please
tell me what these scores mean?
FSIQ = 110
VCI = 115
PRI = 103
The WAIS-IV indexes are:
Verbal Comprehension Index (VCI) - reflects an individual's ability to
understand, use and think with spoken language. It also demonstrates the
breadth and depth of knowledge acquired from one's environment. It
measures the retrieval from long-term memory of such information.
Score given: 115 (High Average)
Perceptual Reasoning Index (PRI) - reflects an individual's ability to
accurately interpret, organize and think with visual information. It
measures nonverbal reasoning skills and taps into thinking that is more
fluid and requires visual perceptual abilities.
Score given: 103 (Average)
Working Memory Index (WMI) - reflects an individual's ability to take in
and hold information in immediate awareness and then perform a mental
operation on that information. It also measures the mental manipulation
of number operations.
Score given: 98 (Average)
Processing Speed Index (PSI) - reflects an individual's ability to
process simple or routine visual information quickly and efficiently. It
measures visual and motor speed.
Score given: 106 (Average)
Full Scale IQ (FSIQ): 110 – High Average
WAIS-IV DESCRIPTIVE CLASSIFICATION AND PERCENTILE RANK
|| Percentile Range
130 and above
|| 98 to 99.99
|| Very Superior
|120 to 129
||91 to 97
110 to 119
|| 75 to 90
|| High Average
90 to 109
||25 to 73
80 to 89
|| 9 to 23
70 to 79
|| 2 to 8
69 and below
|| .01 to 2
|| Intellectual Deficient
The rest are scaled scores that make the composite scores in each of the
four categories. For further understanding, see here:
VERBAL COMPREHENSION SUBTESTS - Similarities (S), Vocabulary (V),
Information (I), Comprehension (C).
PERCEPTUAL REASONING SUBTESTS - Block Design (BD), Matrix Reasoning
(MR), Visual Puzzles (VP), Picture Completion (PC), Figure Weights (FW).
WORKING MEMORY SUBTESTS - Digit Span (DS), Arithmetic (A), Letter-Number
PROCESSING SPEED SUBTESTS - Symbol Search (SS), Coding (CD),
The Minnesota Multiphasic Personality Inventory (MMPI) is a
psychological test that assesses personality traits and psychopathology.
It is primarily intended to test people who are suspected of having
mental health or other clinical issues but also used for the common
The MMPI-2 is designed with 10 clinical scales, which assess 10 major
categories of abnormal human behaviour, and four validity scales, which
assess the person's general test-taking attitude and whether they
answered the items on the test in a truthful and accurate manner.
The 10 clinical Scales are:
• 1 Hypochondriasis (Hs)
• 2 Depression (D)
• 3 Hysteria (Hy)
• 4 Psychopathic Deviate (Pd)
• 5 Masculinity-Femininity (Mf)
• 6 Paranoia (Pa)
• 7 Psychasthenia (Pt)
• 8 Schizophrenia (Sc)
• 9 Hypomania (Ma)
• 10 Social Introversion (Si)
The scores are indicated based on T-Scores. Score interpretations are:
T >65 indicates high score and needs intervention.
T = 45-54 Average score; no interpretation
T < 45 Low score; no interpretation
I do not administer the MMPI so it is best if the owner of the scores
described could see a psychologist to understand the breakdown of the
scores for intervention. Some information can be found
on this site.
Hope that helps clarify some doubts. Good luck!
