Intervention

The potential participants of this study are already under the care of the investigators, whether this is from a Health or Educational perspective. This aspect is of great importance as there is no intervention from anyone who is unfamiliar. It is also routine that any medications the children require are administered by designated teachers at the school. The methodology to be used in this study permits this routine to be maintained.

The parent/s and or guardians of all children in years 6 to 11 (ages 11-16 years) attending Cambridge Park Special School in Grimsby will be invited to attend one of a number of meetings in early September at which the study will be explained to parents / guardians. For those parents / guardians who can not attend any of the school meetings a member of the CPS teaching team will make a home visit to inform them of the study. Home visits to parents / guardians is routine at CPS. Following the meetings parents / guardians will be approached and again with verbal along with written study information being provided to them. Parent/s and or guardians will be given one week to decide whether they wish their child can participate or not. If they decide yes, then they will be asked to sign a consent form. However, they will be reassured that they are free to withdraw their consent at any time without giving a reason. Additionally, they will be informed that the investigators may withdraw their child from the study if that is regarded as in the child's best interests.

If at all possible children will also be asked to agree their participation, although realistically this will probably only be feasible in a few children.
To help raise the awareness of parents that the study is planned, a number of posters will be displayed in the reception area of the school. As a routine part of the schools cycle of testing, each child is tested at school in June /July of each year. This has already been undertaken at Cambridge Park Special School. Only once consent has been obtained, will these test results will be included as part of this study for those children whose parents / guardians have provided consent. The tests are as follows:
1. Youngs Reading test
2. Youngs Maths Tests
3. Schonell Group Spelling Test
4. Nelson Insight Self Esteem Test.

Following this, children will be match paired. Matched pairing will be carried out by the Educational psychologist. Great care will be taken to ensure that the matching process will consider all aspects and in particular, for age, sex, socio-economic status and ability.

Once the pre-assessments have been completed, children in matched pairs will be randomised to either ‘Fish Oil’ or ‘Placebo’ Resulting in one child in the matched pair receiving the fish oil (500 milligrams in two small capsules) and the other receiving the placebo. Randomisation will be computer generated using the Statistical Package for Social Services (SPSS). The randomised intervention will be written on paper and placed in envelopes in numerical order. The envelopes which will be used in numerical order will be kept securely in the office of the Head Teacher at Cambridge Park Special School. Once a randomisation number has been allocated, the participants will only be identified by that number for the duration of the study and will only receive the allocated intervention. For the purpose of code breaking, a master copy of the randomisation will be kept securely by the Northern Lincolnshire & Goole Hospitals NHS Trust (NL&G) Research & Development Department (R&D) and in a sealed envelope by the head teacher at CPS in the event that the R&D Department can not be contacted. This copy will only be opened if there is no other alternative.

The placebo and the fish oil will be offered as two small capsules which will be indistinguishable from each other by external appearances, smell or taste and will be produced and provided free of charge by the manufacturer, Croda Chemicals Europe Ltd. Croda Health Care.

Administration of the fish oils / placebo (two small capsules) will be in school (Monday - Friday) on a daily basis and in term time only. During half term, school holidays and weekends it will not be administered. This is to reduce the element of chance. If parent/s guardians were asked to administer the fish oils / placebo an element of non-compliance may result which has the potential to skew or invalidate the results. If a child has a protracted absence, defined as five consecutive days or longer, from school they will be withdrawn from the study as a protocol violation.
As routine the tests as identified above will be repeated towards the end of the school year.

The total duration of the study will be up to 9 months. Following the second set of testing the two sets of test results will be analysed. The Omega3 / Placebo will be administered by trained members of CPS school staff, who routinely administer medicines. This will be conducted in accordance with the school policy. As routine all medications which are administered at school are recorded on a dedicated medicines chart. The same chart will be used for this study intervention and will be colour co-ordinated with the labels of the containers of Omega 3 / Placebo. All medicine charts will, as routine be kept in a locked filing cabinet in the head teachers office. Only the head teacher and the trained CPS staff will have access to the charts.
