The increase of single-parent families causes an increase in psychosocial problems and illness associated with stress. Divorce, separation, and lone parenting have now surpassed death as a cause of single-parent families. They are major life events, and the family physician who helps anticipate them and facilitates adaptation of the family can help prevent associated morbidity and mortality. A non-judgmental approach and understanding of system theory helps in assessing the single-parent family and its stresses. As in medical areas, diagnosis precedes treatment, appropriate assessment indicates management strategies. The acronym 'PRACTICE' describes an assessment tool for the areas likely to be problematic in single-parent families. The difference between the divorced, widowed and the never-married and their coping strategies are described.
