Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants in the intervention group will participate in one group session (approximately 30 minutes), where they will be provided with information about sedentary behaviour, screen time and active play for their child. The session will be delivered by the PhD Candidate/Project Manager during the participants' playgroup time (at the usual playgroup setting). At this session they will receive, and be talked through, a booklet with information about the behaviours, guidelines for sedentary behaviour and physical activity in early childhood, ideas for active play and limiting screen time, and information about goal setting. They will then be asked to set two SMART (Specific, Measurable, Attainable, Relevant, Time-bound) goals relating to the outcomes of the study: one for increasing active play and one for limiting screen time. Parents will also receive 2-3 tailored text messages per week (for 6 weeks), which will include tips for limiting sedentary behaviour, ideas for active play, and prompts to check their progress with their goals.

Outcomes
Primary outcome [1] 298243 0
Change in screen time (minutes per day) measured by parent-report (reliability previously established)
Timepoint [1] 298243 0
Pre-intervention (baseline) and post-intervention (6 weeks post intervention commencement)
Primary outcome [2] 298244 0
Change in sedentary time (minutes per day) measured objectively with activPAL accelerometers (valid and reliable in this population). activPALs will be worn for 7 consecutive days at both timepoints.
Timepoint [2] 298244 0
Pre-intervention (baseline) and post-intervention (6 weeks post intervention commencement)
Secondary outcome [1] 323697 0
Feasibility: recruitment and retention - recruitment numbers will be recorded and retention calculated by the number of participants still enrolled in the program post-intervention
Timepoint [1] 323697 0
Post-intervention (i.e. 6 weeks post intervention commencement)
Secondary outcome [2] 323812 0
Feasibility: dose delivered - measured by attendance at the group session and with purposed-designed parent survey questions (e.g., "How many of the text messages did you read/click through to the links?")

Timepoint [2] 323812 0
Post-intervention (i.e. 6 weeks post intervention commencement)
Secondary outcome [3] 323813 0
Feasibility: engagement in the intervention - measured by parent responses to goal-checking text messages and qualitative telephone interviews (asking questions usefulness/relevance of the session and text messages)
Timepoint [3] 323813 0
Post-intervention (i.e. 6 weeks post intervention commencement)
