Research summary
Feeding disorders are poorly recognised by clinicians and often go undiagnosed. Together with colleagues in the USA, we have been developing a structured clinical interview - The Pica, ARFID (Avoidant/Restrictive Food Intake Disorder) and Rumination Disorder Interview (PARDI). This interview consists of questions about eating and feeding difficulties, answers to which will help health professionals to correctly diagnose and assess the severity of these disorders. It has been trialled in our UK and US clinics and we now need to do a formal study to see if it is accurate and useful in diagnosing and assessing severity compared with expert opinion.
The latest edition of the DSM-5 (a manual containing descriptions of all known psychological, emotional and behavioural disorders) contains three feeding disorders: Pica (eating non-food items), Rumination Disorder (repeatedly regurgiting food) and ARFID (a form of severely restricted eating). The first two appeared in the previous edition of the DSM in a section on disorders in childhood, but ARFID is a new category which is not well-known or understood currently. All three can occur in both adults and children. There is a need for a standardised interview to help clinicians to diagnose these disorders and measure how severe they are.
The concerns of parents of children with feeding disorders are often dismissed by health professionals, and children may go untreated for years with negative effects on physical and mental health. Families of patients attending the Feeding Disorders Service at GOSH have often had great difficulty in getting help for their child. A reliable measure of feeding disorders would reduce negative impact by improving accurate diagnosis and helping with treatment-planning through identifying each child's pattern of difficulties. Ultimately, the PARDI could be used in any setting where children with feeding problems are seen - from GP surgeries to specialist feeding services.REC name
