Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention (smalltalk program) is based on an evidence based model which comprises of two child-focused domains (Quality Everyday Interactions and Stimulating Environment) and two parent-focused domains (Parent Self-Care and Parent Confidence). It also includes a fifth domain, Community Connectedness. The smalltalk program seeks to build on existing parenting strengths and target specific parenting skills known to promote child language and learning. It incorporates strategies that assist parents to adequately meet their own needs as a person and a parent.

The intervention is embedded in two existing service platforms – Maternal and Child Health (MCH) parent groups for children aged 6 to 12 months and Supported Playgroups (SPG) for children aged 1 to 3 years. The intervention is delivered across two levels of intensity – lower intensity: a supported playgroup or parenting group that includes smalltalk parenting strategies and higher intensity: a supported playgroup or parenting group that includes smalltalk parenting strategies plus individual coaching of families in their home.
In the SPG platform: the lower intensity program involves 1 x 2 hour group session per week over a period of 10 weeks; and the higher intensity program involves 1 x 2 hour group session per week over a period of 10 weeks, plus 1 x 1 1/2 hour home coaching visit fortnightly (total of 6 visits).
In the MCH platform: the lower intensity program involves 1 x 2 hour group session per week over a period of 6 weeks; and the higher intensity program involves 1 x 2 hour group session per week over a period of 6 weeks, plus 1 x 1 1/2 hour home coaching visit fortnightly (total of 6 visits).

Behaviour
Comparator / control treatment
The comparator group is a usual care or standard supported playgroup or parent group that does not include any smalltalk parenting content.
The groups run for 2 hours each week for a period of 10 weeks in the SPG platform and 6 weeks in the MCH platform.
Control group
Active

Primary outcome [1] 262248 0

Primary outcome [2] 262249 0
Home learning environment outcomes: Improved parent activities with their child (Eg. Parent reads books to child), parent verbal responsivity (Eg. Parent plays rhyming games with child), home literacy environment (Eg. Literacy exposure). Decreased household chaos (Environmental chaos in the home scale).
These constructs will be measured through questionnaires (self report).
Timepoint [2] 262249 0

Secondary outcome [1] 273386 0
Child outcomes: Enhanced child language and emergent literacy. Expressive and receptive communication was assessed using the following: Ages and Stages Questionnaire: 3rd Ed. - Communication sub-scale; Communicative Development Index: SF; Infant Growth and Development Indices - ECI.
These constructs will be measured through questionnaires (parent self report) and in-home observation.
Timepoint [1] 273386 0

Child outcomes: Enhanced child socio-emotional wellbeing and general development. These outcomes were assessed using 4 behavioural difficulty items from the NEILS study; Ages and Stages Questionnaire: 3rd Ed. - Fine motor and Personal-social sub-scales; Infant Growth and Development Indices - IPCI).

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)
Recruitment
Regardless of whether they are eligible for the maternal and child health platform or the supported playgroup platform, participants will be identified via MCH services or community referrals in their local government area (LGA). A rolling recruitment strategy will be applied.
The MCH representative or community service organisation (CSO) will briefly introduce the study to the family. If willing, the MCH representative or CSO will obtain verbal consent from the family and pass their details onto the LGA’s Site Coordinator. The Site Coordinator will contact the family, explain the study in more detail, obtain verbal consent and mail out a Participant Information and Consent form. When the researcher visits the family’s home for the first home assessment, they will ask the family to provide their written consent.

Allocation concealment:
A computer program designed by Dr Ukoumunne from the MCRI will be used to ensure the appropriate randomisation occurs. This will be conducted independently by Dr Ukoummune (or staff member) for this process.
As the unit of randomisation is the locality, concealment occurs at the level of locality. Sites and localities will be randomised and informed of the outcome of the randomisation, after they have given full consent to participation in the trial. As individual participants are recruited to programs (conditions) offered by their nearest service, they will not be blinded to allocation at recruitment.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
This study employs a stratified, blocked, cluster randomised design. Individual participants are clustered according to the geographical location of their nearest service (the locality identified for participation in the research), with localities randomised within strata to one of three intervention conditions (condition 1 = usual care group; condition 2 = group with smalltalk parenting strategies; condition 3 = group with smalltalk parenting strategies plus home coaching). Each locality will be assigned 1 program variant (condition), i.e. the locality is the unit of randomisation. Stratification is used to ensure that conditions are randomised in a blocked design, to provide at least one program for each condition within each site (LGA or combination of LGAs).
As there are three conditions, randomisation occurs in blocks of three localities, as follows:
1) Each site (LGA or combined LGA) will provide the study team with the finalised list of localities available to conduct programs. Localities in each site (LGA) will be stratified into blocks of three. Where the number of localities within a site is a not multiple of three (e.g. 4, 5, 7 or 8 localities), the first 3 (or 6) localities will be put in the within-site blocks. The remainder will be placed in a ‘pool’ to create cross-site blocks with the ‘left-over’ localities from other sites.
2) Within-in site blocks will be randomised in a balanced design: 1 locality in each block will be randomised to conditions 1, 2 and 3.
3) Localities in the cross-site pool will be allocated into blocks of three, with the ‘left-over’ localities from the same site, allocated to the same block (thereby ensuring that these localities by nature of their block allocation, will be randomised to different conditions). Localities in each cross-site block, will then be randomised in a balanced design to conditions 1, 2 and 3.
