MMPI Code Type Analysis 3 — Questions and Answers
Question 1: Code type stability refers to whether the two highest scales remain the same across test administrations. Which factor MOST undermines code type stability?
- Elevated L scale above T=65
- Scales that are only marginally elevated (T=65–69) with little separation from other scales (Correct answer)
- A high number of True responses
- Age above 60 years
Correct answer: Scales that are only marginally elevated (T=65–69) with little separation from other scales
When the two highest scales are only marginally elevated and close in elevation to other scales, slight response variation can shift the code type, reducing stability.
Question 2: A forensic evaluator encounters a 3-4 code type in a defendant charged with domestic violence. Which characteristic is empirically associated with this code type?
- Exaggerated somatic complaints and secondary gain
- Chronic anger that is expressed indirectly or through periodic explosive outbursts (Correct answer)
- Severe paranoid ideation and persecutory beliefs
- Profound cognitive disorganization and formal thought disorder
Correct answer: Chronic anger that is expressed indirectly or through periodic explosive outbursts
The 3-4 code type (Hysteria and Psychopathic Deviate) is associated with chronic resentment and anger that alternates between surface cooperativeness and explosive outbursts.
Question 3: What does 'code type well-definedness' mean in MMPI-2 interpretation?
- The profile contains no elevated scales above T=65
- The two highest scales are clearly separated in elevation from the third-highest scale (Correct answer)
- The F scale is within acceptable range
- The code type matches a DSM diagnosis exactly
Correct answer: The two highest scales are clearly separated in elevation from the third-highest scale
A well-defined code type exists when there is a meaningful T-score gap (≥5 points) between the second and third highest scales, making the two-point designation more stable and interpretable.
Question 4: The 1-2 code type is most commonly found in individuals presenting with which constellation of symptoms?
- Antisocial behavior and substance abuse
- Somatic complaints and depression, often in chronic pain populations (Correct answer)
- Grandiosity and pressured speech
- Paranoid ideation with auditory hallucinations
Correct answer: Somatic complaints and depression, often in chronic pain populations
The 1-2 code type (Hypochondriasis and Depression) is frequently seen in chronic pain patients and those with somatic preoccupations accompanied by depressive affect.
Question 5: A 2-4 code type in a substance abuse treatment setting suggests which prognosis concern?
- High risk of psychotic decompensation
- Chronic dissatisfaction, resentment, and poor treatment compliance (Correct answer)
- Rapid symptom resolution with standard treatment
- Conversion to somatic symptoms after detoxification
Correct answer: Chronic dissatisfaction, resentment, and poor treatment compliance
The 2-4 code type combines depression with psychopathic deviate features, predicting chronic unhappiness, resentment toward authority, and difficulty sustaining therapeutic engagement.
Question 6: In interpreting code types, the concept of 'profile elevation' refers to which characteristic?
- The height of the F scale relative to the K scale
- The overall mean T-score across all clinical scales (Correct answer)
- The number of scales above T=70
- The difference between the highest and lowest clinical scale scores
Correct answer: The overall mean T-score across all clinical scales
Profile elevation describes the average level across clinical scales, with higher overall elevation indicating greater severity of psychological disturbance.
Question 7: Which code type is most frequently associated with a histrionic personality presentation and conversion symptoms?
- 4-9
- 6-8
- 1-3 (Correct answer)
- 2-7
Correct answer: 1-3
The 1-3 code type (Hypochondriasis and Hysteria) is the hallmark profile for histrionic personality features and conversion disorder, reflecting somatic focus with psychological denial.
Code type stability refers to whether the two highest scales remain the same across test administrations.
