Psychosocial aspects in phenylketonuria.
Psychosocial aspects in phenylketonuric (PKU) patients are reported. In two separate studies patients with PKU differing in age (children versus adolescents), were assessed. The main message of the first prospective study on 58 10-year-old patients is that normally intelligent PKU patients who were treated early and strictly did not show a higher risk for severe emotional and behavioural maladjustment compared with healthy controls at the age of 10 years. The data were obtained in the course of the German PKU Collaborative Study by the "Personality Questionnaire for Children (PFK 9-14)". All patients received nutritional, medical, and psychological counselling every 6 months. In the second retrospective study, 34 early treated, normally intelligent adolescents with PKU (age: mean = 14.6, SD = 2.0, range = 11-18 years) and their mothers were assessed with several psychometric personality inventories and self-developed questionnaires concerning their psychosocial situation and their disease- and diet-specific knowledge. Using the Mannheimer Biographic Inventory (MBI), the Personality Questionnaire for Children (PFK 9-14), and the Freiburger Personality Inventory (FPI) the adolescent patients described their social life and their emotional development as being distinctly restricted. Their knowledge concerning disease and diet was alarmingly poor and the majority had great difficulties in satisfactory dietetic management without parental help. In addition to the burdensome diet, developmental crises like puberty may cause more frequently emotional and behavioural problems in PKU patients.
