Effectiveness of a video self-modelling (VSM) intervention was examined with primary schoolchildren who attended a full-time special education programme for pupils with social emotional and behavioural difficulties and who exhibited inappropriate behaviour during small-group reading instruction. A randomised multiple-probe baseline design was used in this study in four subjects with a follow-up phase 6 weeks after intervention. Four children aged 10 were videotaped during reading instruction to determine levels of active learning and behavioural difficulties. Intervention took place at the teacher's desk or table 3-5 minutes immediately before the child's designated time for reading group instruction. During intervention, the children were shown carefully selected brief segments of their own video that had been recorded during the previous session. Results indicated VSM was an effective intervention for increasing active learning responses and for reducing behavioural difficulties during reading instruction. Optimum results were maintained for more than 8 weeks after intervention. These results support VSM as an effective antecedent intervention and add to the growing body of evidence-based practices for elementary school pupils who have social emotional and mental health difficulties.
