How Families Prepare Their Children for Tooth Extraction Under General Anaesthesia: Family and Clinical Predictors of Non-compliance with a 'serious Game'

Objective: To explore family and clinical factors for usage of an online serious game designed to prepare children with ECC for dental treatment under general anaesthesia.

Design: Observational study. Secondary data of 60 children, aged 5-to-7, randomised to the intervention group in a phase-III randomised controlled trial [NIHR Portfolio 10006, ISRCTN: 18265148] testing the efficacy of the serious game http://www.scottga.org (available online). Usage was captured automatically, with each click, in real time. The total number of replays and total number of missing slides per game-run performed by the child, were recorded and used to monitor usage. Compliance outcomes were: total time running the game and number of completely missed slides.

Results: 57/60 played the game. Median age of parent/carer was 32. For 74% of the families, fathers resided at home and for 65% the parent/carer had A-levels-to-university education. At recruitment, 70% of the children were reported as anxious/highly-fearful and 37% as "significantly psychologically disturbed".

Conclusions: Factors for non-compliance were absence of a father at home (P = 0.01) and higher child-anxiety (P = 0.01) and, to a lesser extent, a low parent/carer education level (P = 0.09). Interactive cartoons featuring dental assessment, oral health messages and modelling featured in the more popular slides.
