Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention will involve the delivery of C2u text messages to participants in addition to standard practice. The content of the C2u text messages are based on antenatal and postnatal care, focusing on health behaviours (maternal nutrition and weight; physical activity; alcohol, tobacco, drugs, medication consumption; immunisation reminders; appointment reminders), mental health and wellbeing, communication, bonding and attachment, infant feeding, preparing for parenthood/ becoming a parent, and circle of security.

The intervention will commence at 16 weeks' gestation, with a duration period of around 12 months. The intervention will cease once the infant is six months of age.

For the first 12 weeks of the intervention, the participant will be sent two text messages a week. This will be reduced to one text message a week, after the first 12 weeks, and until birth. After birth, the participant will be sent two text messages a week for the first 12 weeks. This will be reduced to one text message for the remaining weeks of the intervention.

Eligibility
Key inclusion criteria
Recruitment of Mothers:
Mothers are twelve weeks pregnant and over, has a mobile phone, is over 16 years of age, does not require interpreter services, does not suffer from psychosis, and does not plan to place infant in foster care or adoptive care.

Potential recruitment for postnatal analysis will occur in the late antenatal stage. As such, mothers can be recruited from 12 weeks' gestation until birth.

Recruitment of Fathers
Partner is at least 12 weeks' gestation and is over 16 years of age. Father is required to be over 16 years of age, owns his own mobile phone, does not require interpreter services, does not suffer from psychosis, and does not plan to place infant in foster care or adoptive care.

Potential recruitment for postnatal analysis will occur in the late antenatal stage. As such, fathers can be recruited from when partner is 12 weeks' gestation until birth.

Key exclusion criteria
Exclusion criteria for mothers:
Mothers who are not yet 12 weeks pregnant and/or are under 16 years of age. Furthermore, mothers who do not own a mobile phone, suffer from psychosis, require interpreter services, and/or plan on placing infant in foster care or adoptive care will be excluded.

Exclusion criteria for fathers:
Partner is not at least 12 weeks' gestation and/or is not over 16 years of age. Furthermore, fathers who do not own a mobile phone, suffer from psychosis, require interpreter services, and/or plan on placing infant in foster care or adoptive care will be excluded.

Statistical methods / analysis
Two sample situations were considered based on the presence or absence of intervention. It was hypothesized that the mean or proportion of the main outcomes of interests would be different among the participating mothers and fathers belonging to the intervention and control arms, after the antenatal (at T2) and early life interventions (T4).
For sample size calculation, it was assumed 5% level of significance and 80% power. Further, it was assumed 1:1 ratio for the number of participating mothers and fathers in intervention and control arms. STATA version 8 was used for sample size calculations.
Non-response and loss to follow up together (after enrollment) were expected to be 30% at T2 and 50% at T4, as compared to the enrolled numbers at T1, among the participating mothers and fathers belonging to the control arm. This rate is expected to be less among the intervention arm participants. But, it was assumed the same rate of non-response among the participants of both the arms in order to be on the safe side. Also targeting the same number of enrollments in both the arms was easier in terms of randomization.

SPSS will be used to evaluate and analyse the data gathered. A statistical analysis will be performed to compare control and intervention groups for:
- Data Collection 1 and 2 (pre and post antenatal group)
- Data Collection 3 and 4 (pre and post postnatal group)
- Data Collection 1 and 4 (pre and post of the entire group of participants).

To ensure both control and intervention groups will be comparable at baseline, a number of statistical analyses will be performed. In order to assess differences between control and intervention groups in variables measured at a categorical level, Chi square tests will be used.

To ensure that parental attachment, maternal confidence, infant feeding intentions/practices, and health behaviours are comparable at baseline across intervention and control groups, Independent samples t-tests will be performed.

Mann-whitney U test will be used in the case of non-normally distributed data.

Pearson and Spearman correlation tests will be performed to look at the correlations between parental attachment , and/or maternal confidence, and/or infant feeding intentions/practices, and health behaviours.

Independent samples t-test and Mann Whitney U tests will be used to examine the mean differences in parental attachment , and/or maternal confidence, and/or infant feeding intentions/practices, and health behaviours across independent variables.

ANOVA will be used to observe the mean differences between various demographics and parental attachment , and/or maternal confidence, and/or infant feeding intentions/practices, and health behaviours scores.

Furthermore, a Kruskal-Wallis test will be perfomed to determine significant differences between parental attachment, and/or maternal confidence, and variable demographics scores. Mann-Whitney U tests will be undertaken to determine where the significant differences occurred.

Wilcoxon signed rank tests will be used to examine mean differences between parental attachment pre and post of the intervention (DC1 and DC2; DC3 and DC4; DC1 and DC4) and maternal confidence pre and post of the intervention (DC3 and DC4) in both the control and intervention groups.
