Table 2 Evaluation data collected for the PEACH™ QLD Project against the RE-AIM framework dimensions

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].

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].
