MMPRI-2 RF Online Test: Understanding Standard Deviation and Codetypes

The Minnesota Multiphasic Personality Inventory-2 (MMPI-2) is a widely used psychological test that assesses an individual's personality, psychopathology, and mental health. One of the key concepts in understanding the MMPI-2 is standard deviation, which measures variability or diversity. In this article, we will explore the importance of standard deviation in the context of the MMPI-2 RF online test.

Standard Deviation: A Measure of Variability

Standard deviation is a widely used measure of variability or diversity in statistics and probability theory. It represents how much individual data points deviate from the mean value. In the case of the MMPI-2, standard deviation helps psychologists understand the level of variability in an individual's responses to the test questions.

The MMPI-2 scores are typically converted to normalized 'T scores' on a scale ranging from 30 to 120. A T score above 65 is considered clinically significant and open for interpretation by the psychologist. The 'normal' range of T scores is from 50 to 65, with a standard deviation of 10 points per deviation.

Codetypes: Identifying Patterns in MMPI-2 Scores

The MMPI-2 uses codetypes to identify patterns in an individual's responses to the test questions. A codetype is when two scales demonstrate significantly high T scores, with one being higher than the other. For example, a 2-3 codetype suggests significant depression, lowered activity levels, and helplessness.

There are tens of clinical codetypes that have been well-documented and understood, as well as T scores that 'spike' on a single Scale (such as a 'Spike 4', which would be a sign of impulsive behavior, rebelliousness, and poor relationships with authority figures).

Interpreting MMPI-2 Scores

After the MMPI-2 is taken and scored, an interpretive report is constructed by the psychologist. The score average is around 50, with a standard deviation of 10 points per deviation. Certain combinations of answers to the questions will add or minus 1 point from your score, resulting in a final result.

In conclusion, understanding standard deviation and codetypes is crucial for interpreting MMPI-2 scores accurately. By recognizing patterns in an individual's responses, psychologists can gain valuable insights into their personality, psychopathology, and mental health. The MMPI-2 RF online test provides a comprehensive assessment of an individual's psychological profile, enabling healthcare professionals to develop effective treatment plans.
