Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Usage pattern and users’ feedback were the primary variables of interest. Automated data from Top Tips ‘only’ and Top Tips ‘plus’ users were collected over the 3-month intervention period to assess usage patterns (number of log-ins; pages viewed; plans made; total time spent on the app in minutes and the number of times weight was logged and each tip was achieved). To assess acceptability of the Top Tips apps, eight open questions relating to users’ experience of using the apps were included in the online follow-up questionnaire at 3 months. | — |

| Measure | Time frame |
|---|---|
| 1. Weight and height were self-reported using an online questionnaire at baseline and 3-month follow-up 2. Overall frequency of the target behaviours was measured online using a 16-item questionnaire (developed previously for the 10 Top Tips intervention on a 5-point Likert scale) at baseline and 3-month follow-up 3. Dietary intake was measured online using validated food frequency questionnaires (assessing fruit and vegetable; sweet snack and sugar-sweetened drinks intake on a 7-point Likert scale) at baseline and 3-month follow-up. 4. Fat intake was measured online using the dietary fat scale from the validated Dietary Instrument for Nutrition Education (DINE) at baseline and 3-month follow-up. | — |
