Recruitment
Although the term “parent” will be used throughout this article, this term includes guardians, additional family, or individuals that provide care to children who bring them to well-child visits. Parents were recruited during routine child health supervision visits. They received written information about the study and those who were interested in participating contacted the research team. Posters were used to promote the study; participation was voluntary and written consent from parents was obtained. Inclusion criteria were (1) being a parent of child who was younger than 3 years, (2) having a smartphone or a tablet with iOS or Android operating system, and (3) having the MCHH and can read and answer the questionnaires. Parents were required to participate in 2 visits, 2-6 months apart depending on the child’s next health supervision schedule. Parents who could not be present at both visits were excluded.
