Evaluation data collected for the PEACH™ QLD Project against the RE-AIM framework dimensions
| RE-AIM dimension and definition | Level (source) of data | Data collected (O/I/P)a | Tool used/items generated | Further detail and references | |
|---|---|---|---|---|---|
| REACH | Proportion of the target population that participated in the intervention | Individual (Family) | Number of families enrolled (P) | Purpose-developed database | Recruitment and enrolment databases developed, unique nine-digit ID allocated at enrolment |
| Family demographics (P) | Questionnaire | Family demographics included family composition, parent education, ethnic background and income level. It is adapted from a previously used data collection form [34]. | |||
| EFFICACY/EFFECTIVENESS | Success rate if implemented as in guidelines; defined as positive outcomes minus negative outcomes | Individual (Facilitator) | Changes in knowledge, skills and confidence (I) | Purpose-developed questionnaire | Self-rated on a Likert scale for the practice areas of family-focussed weight management, lifestyle support, behaviour modification |
| Satisfaction with program training and resources (P) | Purpose-developed questionnaire | Parent facilitator satisfaction with program training workshop and program resources was collected pre- and post-training, and post delivery | |||
| Individual (Child) | Child anthropometric measures (O) | Standardized measures for weight, height, waist circumference | WHO2007 [35], US-CDC2000 [36] and UK1990 [37] BMI z-scores and UK1990 WC z-scores; children categorised using IOTF thresholds [38, 39] | ||
| Parent-reported child diet (O) | Children’s Dietary Questionnaire (CDQ) scores for 1) Fruits & vegetables; 2) Sweetened beverages; 3) Fat from dairy products; 4) Discretionary foods; and 5) Food behaviours | Forty-item semi-quantitative dietary questionnaire validated to assess diet quality and food behaviours of school-aged children against the Australian Dietary Guidelines [40, 41] | |||
| Core food group serves for: 1) Fruits; 2) Vegetables; 3) Grains; 4) Meats and alternatives; and 5) Dairy and alternatives | Ten-item, parent completed questionnaire to assess intake of the five core food groups of Australian Guide to Healthy Eating (AGHE) validated in a sample of 45 [31]. | ||||
| Parent-reported child physical activity and sedentary behaviours (O) | Children’s Leisure Activities Study Survey (CLASS) | Assessed using the Children’s Leisure Activities Study Survey (CLASS) questionnaire [42], modified to focus on active pastimes and screen-time only. Provides a quantitative estimate of children’s time spent in moderate, vigorous and total physical activity, and in screen-based sedentary activities per day. The parent-completed version was used as it is equal in validity and reliability to the child-completed questionnaire [42], and allowed consistency in survey administration of diet and PA outcomes. | |||
| Child-reported health-related quality of life (I) | Child Health Utility 9D (CHU9D) | 9 item self-completed paediatric generic preference-based measure of health-related quality of life [43]. It gives a utility value for each health state described from which quality adjusted life years (QALYs) can be calculated. Validated in 7 to 17 year olds [44]. | |||
| Child program satisfaction (P) | Purpose-developed group activity and questionnaire | Children’s views of their group sessions were captured via a brief questionnaire and informal group discussion in the last session. | |||
| Individual (Family) | Parenting self-efficacy (I) | Parenting self-efficacy | Four-item questionnaire from the Longitudinal Study of Australian Children [45]. | ||
| Parent barriers, confidence and health beliefs (I) | Purpose-developed questionnaire | Five-item purpose-developed tool to assess parent beliefs about their child’s health, and perceived (pre-program) or actual barriers (post-program) to changing their child’s and family’s health. A further 3 items ask parents to report their confidence to 1) make healthy changes to child and family eating and activity patterns; 2) set limits regarding child food and eating; and 3) set limits regarding child activity/inactivity patterns. These questions are conceptually based on the Health Belief Model [46, 47]. | |||
| Attendance rates (P) | Program sign-in sheets | Purpose-developed sign in sheets for parents at each session | |||
| Satisfaction with program and materials (P) | Purpose-developed questionnaire | Completed by parents at the end of program delivery. Includes satisfaction with program delivery and changes the family has made during the program. | |||
| ADOPTION | Proportion of settings, practices, and plans that will adopt this intervention | Organisation (Facilitator) | Number of facilitators trained (P) | Purpose-developed database and questionnaire | PEACH™ parent facilitator training logs |
| Demographics (facilitators and services) (P) | Facilitator descriptors included gender, age, education, current employment status and experience in adult and child weight management in groups and 1:1 | ||||
| Number of health services/other organisations engaged (P) | For purpose database containing details on each PEACH™ group including organisational setting | ||||
| Stakeholder interviews (P) | Purpose-developed interviews | Semi-structured interviews with facilitators, organisations and stakeholders | |||
| IMPLEMENTATION | Extent to which the intervention is implemented as intended in the real world | Organisation (Facilitator) | Number of facilitators who delivered groups and number of groups (P) | Purpose-developed database | For purpose database tracking facilitator involvement in the program (including demographics, training and program delivery) |
| Adherence to program protocol and session outlines (fidelity) (P) | Purpose-developed questionnaire and session monitoring forms | Facilitators self-rate the quality of the group facilitation and content fidelity, for each session. It is based on a checklist developed for the NOURISH RCT [48]. | |||
| MAINTENANCE | Extent to which a program is sustained over time | Organisation (Facilitator) | Workforce capacity change | This is beyond the scope of the PEACH™ delivery stage | To be determined |
| Organisation (Health System) | Funding committed | ||||
| Individual (Family) | Long term family impact | ||||
