[Maladjustment signs of employees in the MMPI (Minnesota Multiphasic Personality Inventory). I. Psychological maladjustment].

We investigated a relation between occupational maladjustment and personality traits of 669 employees (354 males and 315 females) in 4 stores randomly selected from 35 stores of a distribution business company Firm I. The subjects were classified into 3 adjustment groups; "poor," "average" and "good" as a result of their self-evaluations for occupational maladjustment in each item on the check list comprising 3 major categories of vocational aptitude, human relations to superior and those to colleagues. And we studied the characteristics of the profiles of MMPI according to the 3 categories. The difference between the "poor" and "good" groups was the clearest in the relation between occupational maladjustment and MMPI profiles. Generally speaking, in the validity scale F is higher, and K is lower in "poor" groups, while in the clinical scale Pa, Ma and Si go higher. In conclusion, the personality traits of psychologically maladjusted persons are sensitivity, introversion, lack of suppression, lack of consideration and defense, and lack of plasticity.
