Description of intervention(s) / exposure
The Munch and Move Healthy Menu Planning Workshop is a three hour workshop held in the Hunter New England region of New South Wales. The aim of the workshop is to provide childcare service staff (menu planners and supervisors) with the confidence, knowledge and skills required to plan and provide nutritionally adequate meals to children in care.

Childcare services in the intervention group will be emailed an enhanced invitation six weeks prior to the Munch and Move Healthy Menu Planning Workshop. The email will be distributed by a Health Promotion Officer (HPO) with previous experience working with childcare services.

The enhanced invitation, designed by Health Promotion staff, includes several behavioural ‘nudge’ strategies aiming to increase workshop registration. These strategies include: a testimonial from a previous attendee endorsing the workshop; information highlighting that the workshop contributes to professional development; and a visual reminder to display at the service. These strategies have been previously utilised within other community health promotion activities.

Intervention childcare services who are yet register for the workshop will receive a reminder email, distributed by the same HPO, one week following the initial invitation. The reminder email contains the enhanced invitation, including information regarding the workshop date, time location, and due date for workshop registrations. Childcare services yet to register three weeks following the initial invitation will then receive a reminder phone call from the same HPO to encourage registration. A final reminder email will be distributed to childcare services two weeks prior to the workshop. Internal records by the HPO will be maintained to track delivery of the initial invitation, reminder emails and reminder phone calls.

Childcare services will be asked to register for the workshop by completing a brief online registration form. Workshop attendance will be capped at 30 individuals.

Behaviour
Comparator / control treatment
Childcare services in the control arm will be emailed a generic invite six weeks prior to the Munch and Move Healthy Menu Planning Workshop. The invitations will be distributed by a HPO with previous experience working with childcare services.

These generic invitations have been designed by NSW Office of Preventative Health and include information highlighting the relevance of the workshop to the state-based dietary guidelines for the sector, and regulatory standards The generic invitation will not include any deliberate strategies to increase attendance.

Control childcare services who are yet register for the workshop will receive a reminder email, distributed by the same HPO one week following the initial invitation. The reminder email contains the generic invitation, including information regarding the workshop date, time, location, and due date for workshop registrations. Childcare services yet to register three weeks following the initial invitation will then receive a reminder phone call from the same HPO to encourage registration. A final reminder email will be distributed to childcare services two weeks prior to the workshop. Internal records by the HPO will be maintained to track delivery of the initial invitation, reminder emails and reminder phone calls.

Childcare services will be asked to register for the workshop by completing a brief online registration form. Workshop attendance will be capped at 30 individuals.

Outcomes
Primary outcome [1] 320037 0
Childcare service registration for the Munch and Move Healthy Menu Planning Workshop will be evaluated by comparing the number of childcare services who registered between the intervention and the control arm.
Timepoint [1] 320037 0
The outcome will only be assessed post intervention (on the day of the workshop), approximately six weeks post invitation distribution.
Primary outcome [2] 320038 0
Acceptability of the invitation will be assessed via one item rated on scale (ranging from 1 to 10) administered by a telephone interview. The item was designed specifically for this study Scores will be compared between intervention and control services.
Timepoint [2] 320038 0
The outcome will only be assessed once at follow-up, approximately four months following invitation distribution.
Secondary outcome [1] 370331 0
Childcare service staff intentions to implement dietary guidelines for the sector will be assessed via four items on a 5-point Likert Scale (ranging from strongly agree to strongly disagree) administered by a telephone interview. The items were designed specifically for this study.
Timepoint [1] 370331 0
The outcome will only be assessed once at follow-up, approximately four months following invitation distribution.
Secondary outcome [2] 370332 0
Contextual barriers to workshop attendance will be assessed via five single response items within a telephone interview.
Timepoint [2] 370332 0
The outcome will only be assessed once at follow-up, approximately four months following invitation distribution. The items were designed specifically for this study.

Study design
Purpose of the study
Educational / counselling / training
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
A list of childcare services located in the Hunter New England Local Health District (HNELHD) was obtained through internal records. Childcare services who had not participated in menu planning training in the past three years were identified (n=88).
Childcare service random allocation to intervention and control group will take place centrally using the RAND function in Microsoft Excel 2013. Childcare services were blind to group allocation. The HPO and data collectors were aware of group allocation.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Childcare services were randomly allocated to intervention and control group using the RAND function in Microsoft Excel 2013. Services will be block randomised to the intervention or control group in a 1:1 ratio.
Masking / blinding

Efficacy
Statistical methods / analysis
Statistical analyses will be conducted using SAS 9.3. Descriptive statistics including frequencies, proportions and 95% CIs will be used to describe service characteristics and interview responses. For the primary and secondary outcomes, chi-square and linear regressions will be used to assess differences between intervention and control.

Summary
Brief summary
The study aimed to assess the impact of nudge strategies embedded within an invitation to attend a healthy menu planning workshop, on childcare service workshop registration. We hypothesised that the use of these strategies would result in an increased number of registrations from childcare services that receive the intervention, compared to control. Acceptability of the invitations and contextual barriers to workshop attendance were assessed at follow-up. Intentions to implement dietary guidelines for the sector and service characteristics were also obtained.
