Internal consistency is usually assessed using Cronbach's Alpha, which measures the overall correlation between items as well as the level of correlation between items within a scale.Reproducibility assesses whether an instrument produces the same results on repeated administrations when respondents have not changed. The reliability coefficient is normally calculated by correlating instrument scores for the two administrations.Reliability estimates of 0.7 and 0.9 are recommended for instruments that are used in groups and individuals respectively.Validity is the extent to which an instrument measures what is intended.Computer graphics offer interactive animations, which allow participants to control aspects of the visual display in a trial and error manner.Some investigators have used computer-based questionnaires to see the effects of computer versus paper-and-pencil administration on different types of measures.The SFP was piloted using 40 children (mean age = 9.2 years) from an 'After School' club in Newcastle-upon-Tyne. The instructions and general operation of the program were shown to be sufficiently clear, as the children did not raise any problems or queries.However, there was a problem with the scale and polish item.
The aim of this study was to investigate the reliability and validity of the Smiley Faces Program.As the pilot study progressed it became clear that most of the children had not experienced scaling and polishing, and had very little or no concept of what this procedure involved.Although alternative terminology was used (eg 'electric toothbrush') there was still a lack of understanding, thus this item was removed from the program.The children rated the local anaesthetic and drill as the most anxiety-provoking items.
