This Eriksonian-based instrument provides a measure of the positive and negative attitudes associated with each of the eight developmental stages, the status of conflict resolution at each stage, and an index of overall psychosocial health. Because interpretation focuses on healthy personality development and growth instead of pathology, the MPD is useful in a variety of clinical, counselling, training and research settings.
The MPD consists of 27 scales. Attitudes that describe the basic dimensions of personality are measured by eight Positive and eight Negative scales. The direction and degree of resolution between the Positive and Negative scales is reflected in the eight Resolution scales. Three Total scales provide measures of overall psychosocial adjustment. Users respond to the 112 items on a separate answer sheet using a 5-point scale ranging from very much like me to not at all like me. Results are reported as T scores or percentiles and may be plotted on profile forms by sex and by age group (13 to 50 years and older).
The MPD was normed on a sample of 2,480 males and females ages 13-86 years. Test-retest reliability coefficients for the MPD scales uniformly approach or exceed .80 with one exception (.67). Alpha coefficients for the Positive and Negative scales range from .65 to .84.
