Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Decisional conflict . This assessed a parent?s perception that their decision was informed in accordance with their values and can be acted upon. This 16-item validated scale has five sub-sections: informed, values clarity, support, uncertainty and effective decision. Scores range from 1 (no decisional conflict) to 5 (extremely high decisional conflict). Scores lower than two are associated with implementing informed decisions, higher scores are interpreted as delaying decisions or feeling unsure about their implementation. | — |

| 1. First dose MMR vaccination uptake data for children of participating parents (provided by GP practices) 2. Knowledge about MMR and the measles disease was measured using 11 multiple choice items. 3. MMR immunisation cognitions: The Theory of Planned Behaviour informed items to assess parents? cognitions (attitude, subjective norm, perceived behavioural control) towards having their child immunised with MMR. 4. MMR immunisation trade-off beliefs were measured using a previously modified version of the Beliefs about Flu Vaccination Questionnaire to assess parents? trade-off beliefs on vaccine necessity versus vaccine concerns for MMR . A single MMR immunisation ?trade-off? beliefs score was calculated. A positive score indicates that the parent perceives that necessity outweighs the concerns. 5. Anxiety was assessed by the short form State-Trait Anxiety Index. 6. Parents? engagement with the decision aid or leaflet: Data were collected in the post-intervention questionnaire. Parents in the decision aid arm were asked ?Did you use the MMR website?? (Yes the whole website /Yes but only some of it /No). The time parents spent working through the decision aid was captured by Google analytics. 7. Parents in the leaflet arm were asked ?Did you read the MMR leaflet?? (Yes the whole leaflet /Yes but only some of it / No). 8. All parents were asked to report how long (minutes) they had spent looking at other information about MMR before or since their child was born. 9. Qualitative component: A sub-sample of parents and health professionals were interviewed about their views on the MMR decision aid or leaflet. 10. Eonomic component: Self-reported intended and actual numbers of parent contacts with health professionals and parent MMR-related expenditure were collected. Costs of delivering the MMR interventions (decision aid and leaflet) were calculated. | — |
