Objectives: This study sought to explore the utility of using single system designs (SSD) in an optimal set of circumstances. The effects of a computer network intervention on three outcomes (pain intensity, pain aversiveness, and anxiety) were examined. Method: Meta-analysis of three studies using restricted alternating treatment designs was conducted. Results: Children reported significantly less pain intensity, pain aversiveness, and anxiety in the SBW condition than in the GPM condition. Both sex and age moderated these effects. Conclusions: An SSD/meta-analysis approach can provide multiple views of the impact of an intervention.
