Abstract
Background:

The massive use of technology can be leveraged to facilitate access to growth and development programs for children with access constraints. Existing programs supporting children's growth and development especially for children younger than three years are inadequate and not accessible to most families. In most cases, primary caregivers are unable to identify delayed milestones in their children's growth and development due to inadequate information on how to assess the key developmental milestones, and they often report the cases when they have become very severe. To promote early identification of possible developmental delays, the African Population and Health Research Center (APHRC) together with Val Partners developed, implemented and evaluated the use of mobile phone technology to help young mothers track their children's development.

Objective:

The objective of the study was to develop and test the feasibility of using mobile phone technology for optimizing, tracking, and responding to children's developmental progress.

Study design:

The study employed a quasi-experimental design and used a mixed-methods approach combining quantitative and qualitative methodologies. It was a two-arm study, where the first arm was trained on the use of a mobile phone application to assess their children's growth and development, while the second group received the standard of care provided by community health volunteers (CHVs). A total of 220 mothers/primary caregivers-child dyads were recruited into this study. The causal effect of the intervention was estmated using mixed linear models and the Difference-in-Differences estimator.

Study duration: 24 months

Budget: CAD 250,000

Sampling

Sampling Procedure
The project targeted young mothers (including adolescents) of children under the age of three years and living in informal settlement areas in Nairobi. Community Health Volunteers (CHVs) living within the community were identified and reccruited to assist the study team to recruit mothers/caregivers who are eligible for inclusion. Effort was made to ensure equal representation of genders in the intervention as both fathers and mothers were included during communications and activities related to the project.
Deviations from the Sample Design
N/A
Response Rate
The response rate was 115.45 percent because the original sample size was 220 in total but the baseline round had 254 participants recruited and interviewed
Weighting
The sample size was calculated using G* Power program (18) where the program was set to a two-sided t-test involving the difference between the independent means (18). Using a piori power analysis, we input the values of 0.05 and 0.84 for significance levels and power, repectively. Additionally, equal sample groups were assumed meaning the allocation ration of N1 (Intervention group) to N(Control group) is 1. The calculation produced a sample size of 110 for each group, which allowed for 10% attrition rate gave a result of 110. It was therefore hypothesised that with 100 caregiver-infant dyads in the intervention group and 100 in the control group, the sample size achieves 80% power to detect a difference among two groups, with an effect size of 0.4 at the 5% significance level (two-tailed test). A sample comprising a total of 220 households (caregiver-child dyads) were therefore recruited.

Mode of data collection
Face-to-face [f2f]
Supervision
Data collection was supervised by carefully trained team leaders and the research team. During fieldwork, data quality was enhanced by APHRC team leads through regular spot checks and sit-ins to approximately 5-10% of each field worker's daily work to verify authenyicity of the data collected. The field supervisor certified the quality of the data through editing of the data before they were transfered to the database.
Type of Research Instrument
Two Questionnaires were used during the study
The first one was (1) PARENTAL ASSESSEMENT QUESTIONNAIRE which constituted 4 themes including: Knowledge, Attitudes and Perceptions (KAP) questions, Ages and stages questions (ASQ-3), Parental report questions and stress-efficacy questions.
The second questionnaire (2) CHILD ASSESSMENT QUESTIONNAIRE

Data Processing

Cleaning Operations
Data collection was done electronically using tablets/phones, with spot checks for quality control. Once all the data collection were completed, all the inconsistencies were resolved prior to data analysis. An automated routine to check on the data completeness, correctness and consistency was also run on 100% of the collected data.
Other Processing
Differences in caregiver KAP and wellbeing at baseline and end-line for the intervention and control groups were determined by summing the scores on the items and running a t-test for comparison.

For child developmental outcomes, raw scores were constructed by adding all the items passed for each domain on the PCM-IT. Composite scores were computed by summing the scores across all the domains. As we expected scores on each test to increase with age, the scores were standardized for age to allow for direct comparisons across tests. After the data were cleaned, quantitative data analysis was performed using Stata. A first set of analyses consisted of descriptive statistics. This will allowed us to detect similarities and/or differences between subjects' characteristics across the different groups. We compared some baseline measurements between the control group and intervention group using the t-test adjusted for continuous variables, and cluster-adjusted chi-square for binary variables. The second set of analysis consisted of assessing the causal effect of the ECD intervention in Korogocho via the DID estimator, and mixed linear model. Individual items on the PCM-IT were reviewed for missing data, as well as for floor and ceiling effects. In the case where more than 10% of the responses on the items were missing, the data was excluded from further analysis. The time taken to complete the assessment was calculated. We also calculated the totals by summing the scores of the items included in the tool to establish children's performance levels at baseline and at end-line. This enabled us to identify child development domains that have acceptable variability.

Data Appraisal

Estimates of Sampling Error
The calculation produced a sample size of 100 for each group, which allowed for a 10% attrition rate gaving a result of 110. We therefore hypothesized that with 100 caregiver-infant dyads in the intervention group and 100 in the control group, the sample size achieved 80% power to detect a difference among the two groups, with an effect size of 0.4, at the 5% significance level (two-tailed test). A sample comprising a total of 220 households (caregiver-child dyads) were therefore recruited.
