Recording and EValuating Activity in a Modified Park (REVAMP) Study

Data collection will occur at baseline, 12 months (3 months after intervention completed), 24 months (15 months after intervention completed). All measures will be completed at both parks and at all time points (except for the resident survey which will only be conducted at baseline and 24 months).

1. Park usage and park-based physical activity:
Park usage will be assessed at the intervention and control parks via multiple methodologies:
1.1. Observations of park users will be conducted using the System for Observing Play and Recreation in Communities (SOPARC). This instrument is based on momentary time sampling and involves undertaking systematic observations (scans) of each participant within the park at a particular time on specified days. The observations will record the number of park users and the activity level they are engaged in.
1.2. Intercept surveys with park users will be conducted to examine frequency of park visitation and park-based physical activity. Face-to-face intercept interviews will be completed with English-speaking adult park users on days when observations are conducted. Adults with children will also respond to items regarding their child's park use.
1.3. Local resident surveys with will assess park visitation over the past 3 months and activity levels engaged in when at the park. This survey will be completed by adults and adults with children will also proxy-report items about their child's park use.
1.4. Electronic monitoring of path usage and car traffic will be undertaken to record the number of park users walking and cycling on specified paths and the number of cars entering the parks

2. Active travel to and from the park:
Active travel to and from the park will be assessed via the resident survey and park intercept survey

3. Aspects of the park refurbishment that attract visitors to the intervention park and encourage them to be more active. This will be assessed via the resident survey and park intercept survey.

Resident survey measures:
1. Sociodemographic characteristics :
Standard demographic and socio-economic information will be collected by self and proxy report. Age, sex, marital status, educational attainment, postcode, country of birth, family structure (e.g. siblings, number of people living in household), and dog ownership will be collected in the adult survey, child's age and sex will be proxy reported.
2. Physical activity:
Adults' transportation and leisure time physical activity and time spent sitting will be self-reported using validated measures. Child's time spent outdoors will be assessed using a previously validated proxy-report measure. Child's frequency of meeting physical activity and screen time recommendations will be proxy-reported using validated measures.
3. Neighbourhood social and environmental influences on park use:
A range of items examining perceptions of parks and features important for physical activity, neighbourhood safety, violence, crime, attractiveness, walkability, social norms, social trust and cohesion will be examined. These measures have been previously developed and have acceptable psychometric properties and predictive validity.
4. Biological and health-related measures:
Adults will self-report their height and weight, stress, depression and general health using validated scales
