This step involved making changes to our materials based on some really helpful ideas from our advisory panels.

Some of these changes included:

• Reducing the number of questions in our activity booklet to make it less confusing for children to fill in.

• Having separate information sheets tailored for younger children or older children so that younger children could understand everything and older children would feel well informed.

• Including vlogs (video blogs) as another method of data collection, as this is a popular method of self-expression, particularly for older children.
