Primaire uitkomstmaten
Parent and teacher ratings on the 10-item Conners list and the ADHD rating scale. There are three measurement points: (i) the start of the trial; (ii) the end of the baseline period, and (iii) the end of the diet or control period.
Achtergrond van het onderzoek
80 children, 3-8 years old, are randomly assigned to either a diet group or a control group. After a two weeks-baseline period, 40 children will follow a four-week food elimination diet, whilst the children assigned to the control group will be placed on a waiting list; they will adhere to their normal food pattern. Children in the control group are not offered any other treatment. Identical questionnaires and measurement times are used for the two groups and will be completed by parents and teachers at the start of the trial, after the baseline period and after the diet- or controlperiod. Following the final measurement, families in the control group may also choose to start the food elimination diet.
Doel van het onderzoek
The effects of foods on children with ADHD will be determined in a randomized, controlled trial. Can the results of earlier open-diet trials in the Netherland, i.e. 60% of the participants showed an improvement in behaviour of 50% or more, be confirmed? The prediction tested is that a few foods diet wil lead to a significant improvement of behaviour in children with ADHD.
Onderzoeksproduct en/of interventie
The children are assigned at random to either a diet group or a control group. Each group consists of 40 children. Following the baseline period, the children placed in the diet group will follow a 4-week food elimination diet, whilst the children assigned to the control group will be placed on a waiting list; they will adhere to their normal food pattern. Children in the control group are not offered any other treatment. Identical questionnaires and measurement times are used for the two groups. Following the final measurement, families in the control group may also choose to start the food elimination diet.
