Research objective | Data collected |
To examine the feasibility of the recruitment and sampling procedures | The rates of actual recruitment compared to the recruitment targets were counted in terms of: • Number of schools (clusters) recruited • Number of HPs and teachers recruited to deliver the experimental and control interventions • Total number of children recruited for outcome measurement • Number and proportion of children recruited in each of the 3 subgroups within the stratified sampling frame |
To measure the compliance and fidelity of the intervention delivery and explore the influence of the intervention delivery model on these factors | • Number and percentage of sessions delivered in each school • Structured observations of the delivery of RECALL in the classroom setting carried out by three of the investigators following Carroll et al. [44] (see Additional file 1) • Qualitative data from semi-structured interviews including reasons for any sessions not being completed (see Additional file 2) |
To explore the acceptability of RECALL to HPs and teachers who deliver classroom-based interventions in mainstream schools. | • Measures of compliance and fidelity as an indication of acceptability • Semi-structured interviews • Comments on intervention logs |
To investigate the appropriateness of the outcome measures completed by teachers, children and their parents | • The number and percentage of standardised assessments, teacher rating scales and parent rating scales completed pre- and post-intervention • The research assistants (RAs) report regarding the ease of administration and time taken to complete the battery of standardised assessments with the children |
