Figure A3.

Concept map children, group 3A. In this map, each point reflects one idea. Ideas grouped together more often appear closer to each other on the map. Ideas never/rarely grouped together appear widely separated on the map. A circle means that a new cluster is created by the researchers, by combining original clusters. Clusters are groups of ideas that were grouped together most often and reflect ideas that were related conceptually according to the participants in this group. The defined cluster names in this concept map were: Cluster 1: Unable or reluctant to sleep; Cluster 2: Uncomfortable in bed; Cluster 3: Illness and discomfort; Cluster 4: Stressful and exciting thoughts and feelings. Arrows indicate an idea is reallocated by researchers; idea 7 ‘My parents who make noise in our home’ was moved to Cluster 1.
