Health and physical activity among children with intellectual disabilities

INTERVENTION: Using a random numbers table, participants will be randomly assigned to one of five conditions: 1) no risk information + loss‐framed messages, 2) no risk information + gain‐framed messages, 3) risk information + loss‐framed messages, 4) risk information + gain‐framed messages, 5) control. Parents will receive information and PA messages unique to their condition. Following randomization, participants will complete a series of questionnaires to assess a variety of theoretical predictors of parent physical activity support behaviour and child physical activity participation. Each participant will receive then receive an e‐newsletter specific to their condition. Immediately after receiving the e‐newsletter, participants will be asked to complete a follow‐up questionnaire (FQ1) Two weeks following the completion of FQ1, participants will receive a link to complete a second follow up questionnaire (FQ2) Two months following the completion of the baseline questionnaire, participants will receive a link to complete the final follow up questionnaire (FQ3) All questionnaires and messaging material will be administered online. CONDITION: Parents of children with intellectual disability ; Mental and Behavioural Disorders ; Intellectual disability PRIMARY OUTCOME: ; Parental physical activity support behaviours assessed by parental responses to online questionnaires at baseline, immediately post‐intervention, 2 weeks and 2 months; ; ; SECONDARY OUTCOME: ; 1. Feasibility of the experimental design through whether it is possible to randomize parents to particular conditions and to assess the potential effects of message exposure throughout the study and after data collection; 2. Acceptability of the intervention assessed by parental responses to online questionnaires at baseline, immediately post‐intervention, 2 weeks and 2 months; 3. Participant retention measured by withdrawal from the study at 2 months; INCLUSION CRITERIA: 1.
