Anankastia in personality disorder or personality difficulty

Description

The core feature of the Anankastia trait domain is a narrow focus on one’s rigid standard of perfection and of right and wrong, and on controlling one’s own and others’ behaviour and controlling situations to ensure conformity to these standards. Common manifestations of Anankastia, not all of which may be present in a given individual at a given time, include: perfectionism (e.g., concern with social rules, obligations, and norms of right and wrong, scrupulous attention to detail, rigid, systematic, day-to-day routines, hyper-scheduling and planfulness, emphasis on organisation, orderliness, and neatness); and emotional and behavioural constraint (e.g., rigid control over emotional expression, stubbornness and inflexibility, risk-avoidance, perseveration, and deliberativeness).
