compulsive personality, a type of character structure with a pattern of chronic and obsessive adherence to rigid standards of conduct. The person is usually excessively conscientious and inhibited, is extremely inflexible, has an extraordinary capacity for work, and lacks a normal ability to relax and to relate to other people. The compulsive person is likely to follow repetitive patterns of behavior, such as snapping the fingers, crossing the legs, tapping the foot, or refusing to walk on cracks in the sidewalk, and often leads an impoverished emotional life, being dominated by a need for order, cleanliness, punctuality, rules, and systems.
