| Abstract|| |
Background: Comprehensive instruments to evaluate the child rearing knowledge and practice are not readily available for clinical research. Materials and Methods: We have designed in two phases a new instrument to evaluate the child rearing knowledge and practice under the four major domains of child rearing. Twenty-five subject experts from the field of Paediatrics, Obstetrics, Neurology and Nursing elicited the content validity of the instrument. The test retest reliability was evaluated by 25 young mothers who completed the CRKS at an interval of two weeks. Results: The Content Validity Ratio (CVR) of individual items ranged between 0.6 to 1. The reliability was tested for the 20 individual items of the CRKS using Kappa coefficient. The measurement of agreement Kappa ranged from 0.51 to 1. The total knowledge scores and sub scores data were analysed for correlation using Pearson's correlation coefficient. A significant Pearson's correlation indicated that the total scores were consistent over time (r = 0.89). The sub scores on feeding (6 items), Growth and development (4 items), protection (7 items), and infant stimulation (3 items) were found to have reliability of 0.91, 0.76, 0.84, and 0.89 respectively using Pearson's correlation. Conclusion: The instrument is found to be valid and reliable and can be used to measure child rearing knowledge and practice in early infancy.
Keywords: Child rearing knowledge, child rearing practice scale, reliability and validity

| Introduction|| |
Child rearing (CR) refers to bringing-up of children by parents or parent substitutes. It consists of practices that are grounded in cultural patterns and beliefs. It is probably the most challenging responsibility for a mother during her child's infancy. Successful CR is essential for the child's overall development and realization of self-esteem.  As the primary care giver for infant, mother is responsible for attending to all the needs of the infant. In India, other elder members of the family also contribute to childcare. The important components of CR are maternal activities that promote the children's physical, intellectual, and psychosocial development so that they may grow up to express their full potentials.
The major domains of CR during infancy are feeding, meeting the needs of cleaning, and protection including prevention of accidents and injuries, providing appropriate infant stimulation, and monitoring growth and development. Child rearing practices (CRP) are influenced by child rearing knowledge (CRK). Women with chronic diseases such as epilepsy may have limitations in CR but appropriate interventions can improve baby outcome. ,, Women with epilepsy have poor CRK. Women with frequent seizures may find it difficult to practice CR safely and efficiently and should solicit help and support from family members. By systematically evaluating the CR knowledge and practices, it is possible to identify areas of inadequacy and institute remedial programs, and thereby ensure proper growth and development of the babies. There have been few studies that had comprehensively evaluated CR. Until recently, the entire attention of the medical fraternity had been focused on to breastfeeding. There are several instruments that evaluate the breastfeeding habits of mothers. Nevertheless, there are no scales that examine comprehensively all domains of child rearing. Broad based scales are necessary for evaluating efficacy of any CR intervention programs.
An earlier scale that was used in field trials in Ghana had three indices: a child-feeding index; a preventive health seeking index; and a hygiene index.,  another scale consisted of only age-specific child-feeding index.  These indices did not evaluate the domains of infant stimulation or protection. The investigators experienced the urgent need for a comprehensive scale to evaluate child rearing knowledge and practices applicable to infancy (up to 1 year of age) while attempting to evaluate potential intervention programs for women with epilepsy. The objective of this study was to test the validity and reliability of a newly developed comprehensive scale to evaluate child rearing knowledge and practice in mothers of infants.
| Materials and Methods|| |
This scale was prepared in the Kerala Registry of Epilepsy and Pregnancy in the Sree Chitra Tirunal Institute for Medical Sciences and Technology, in order to evaluate the child rearing knowledge and practice of women with epilepsy. We prepared a draft scale after carrying out an extensive literature survey, consultations with the national guidelines on infant feeding, discussions with experts and mothers on prevailing CR norms. The questions were assembled from the four domains of child rearing. The normative data for infant development was based on Simplified Developmental Information Chart.  These scales were assessed in a pilot study in our institute.  The final version that we prepared had two parts: Child Rearing Knowledge Scale (CRKS) and Child Rearing Practice Scale (CRPS).
The child rearing knowledge scale
The CRKS is designed for administration to women during pregnancy or in post-partum period up to 4 months. This self-reporting type of scale has 20 multiple choice questions on infant care divided into four subscales that covered the four domains of CR viz. feeding (questions 1-6), growth and development (questions 7-10), cleaning and protection (questions 11-17), and infant stimulation (questions 18-20). Each question had five choices: one right choice, three wrong choices, and a 'don't know' choice to avoid the chance of guessing. The correct choice carried two points and other choices were scored as '0'. The range of score for an individual was between 0 and 40. Higher score meant better CRK. The scale is prepared in the vernacular language (Malayalam) and is designed for self-administration in 20 min time. An English translation of the scale is provided in Appendix 1 [Additional file 1]. Mothers were expected to answer the questions all by themselves. The relatives and bystanders were advised not to assist the subject during the administration of the test.
The child rearing practice scale
This section of the scale is designed for administration by the investigator in a face-to-face interview (Appendix 2).[Additional file 2] It consisted of 25 items divided into 4 subscales, that covered the four major child rearing domains related to early infancy and related practices viz. feeding (item 1-7), growth and development (items 8-9), cleaning and protection (items 10-21), and infant stimulation (items 22-25). The domain-cleaning and protection was further sub-classified into hygiene of the baby (items 10-14), infection prevention (items 15-17), and prevention of accidents and injuries of the baby (items 18-21). The items were scored based on the reported behaviors of mothers on these four domains. Out of the 25 maternal behaviors in the CRPS, 3 were rated on a four-point scale and the remaining 22 were dichotomous Yes/No questions. The total CRP score was calculated as the sum total of the four subscale scores and ranged from 0 to 34. Higher scores indicated better child rearing practices. The CRP Scale could be administered in 20 min time.
Testing the scales for content validity and reliability
In the first phase, the draft CRKS was circulated among subject experts and their opinion was taken. The panel of subject experts were from nursing (four postgraduate nursing faculty, two clinical bedside nurses), pediatrics (two teaching faculty with special interest in child development and nutrition), and obstetrics (two postgraduate teaching obstetricians who regularly attend to women with special problems such as epilepsy). Their recommendations and suggestions were incorporated in the instrument.
In the second phase, CVR was determined by distributing the instruments to 30 subject experts including specialists from six institutions. Twenty-seven of them returned the instruments after validation along with their comments, two of whom were excluded because of incomplete data. There were 19 female experts and 6 male experts, which included neurologists (n=4), pediatricians including one pediatric neurologist (n=4), gynecologists (n=2), and 5 each from the field of pediatric nursing, obstetric nursing, and community nursing (n=15). Their professional experience ranged from 2 to 27 years with a mean of 16.36 8.5 years. Each expert was asked to evaluate on a four-point ordinal scale whether or not the individual items in the CRKS (20 items) and the CRPS (25 items) were indeed relevant in measuring the four domains of CR. Items which were rated as "1" corresponded to "least relevant" and a rating of "4" corresponded to "highly relevant." Items rated as 3 or 4 were considered relevant and were included in the final version of the scales after calculating the CVR. The method for determining CVR as developed by Lawshe  is described by the following formula:
where CVR is the Content Validity Ratio, ne is the number of panellists indicating useful/relevant about a specific item, and N is the total number of panellists. The minimum value of the CVR to be significant with 25 panelists is 0.37 per identified item.
Reliability of the scales was evaluated by the test-retest method by administering the test at 2 weeks interval to 25 employed women [Table 1]. Their ages ranged between 21 and 55 with a mean (SD) of 29.9 (9.9) and were working as nurses (19), doctors (2), or clerks (4). The subjects were told the purpose of the study and requested not to review or discuss related information during the 2 weeks interval period and assured that the questions and the correct answers would be discussed with them after the retest. The same test was repeated after 2 weeks. None of them reviewed related materials during this period. All 25 women completed the second test. The results of the two tests were analyzed for measurement of agreement using Kappa coefficient. The total knowledge scores and sub-scores data were analyzed for correlation using Pearson's correlation coefficient.

Content validity ratio
The CVR was calculated as a means of quantifying the degree of consensus among the panel of 25 experts, who evaluated the scales for content validity. The CVR according to the expert panellists ranged from 0.6 and 1.0 for the CRKS [Table 2] as well as the CRPS [Table 3]. The experts had judged that the instrument had good face validity and that all the items were relevant. We prepared the final scales by making certain minor modifications in the wordings and language according to the suggestions of the experts.

The Kappa score for the test-retest reliability test for the CRKS is given in [Table 2]. The mean knowledge score of healthy women for first test was 28.4 ± 5.5 with a range of 18 to 38 and for the retest it was 30 ± 2.9 with a range of 20 - 40. All the individual items except item 11 and 12 were found to have adequate agreement between the two test scores (the measurement of agreement Kappa ranged from 0.51 to 1). Accordingly these two questions and choices were modified. Kappa coefficient could not be calculated for item number 19 and 20 since there was 100% agreement [Table 2].
The total score had significant consistency over time (r = 0.891) according to Pearson's correlation. The sub-scores on feeding, growth and development, cleaning and protection, and infant stimulation were found to have reliability of 0.906, 0.758, 0.836, and 0.89, respectively, using Pearson's correlation coefficient [Table 4].
| Discussion|| |
It is important to have reliable instruments to evaluate CRK and CRP. This study had demonstrated that both the instruments (CRKS and CRPS) had strong validity and reliability for measuring child rearing knowledge and practice. The CVR for individual items in both the CRKS and the CRPS ranged from 0.6 to 1, which indicates that each item measures the child rearing knowledge and child rearing practices as intended (Appendices 1 and 2). The criterion-related validity was not estimated due to the non-availability of similar scales.
The instruments included items supported by current evidence-based information, emphasizing WHO guidelines, and Breastfeeding promotion network of India guidelines. , The WHO and UNICEF recommend that the infants should be given only breast milk for the first 6 months of their life and then breastfeeding should be continued to 2 years or more along with complementary feeding to achieve optimal growth, development, and quality survival.  When the mother is the primary caretaker, mother-infant bonding is established  and it is reduced when the care of the baby is undertaken by a third person.
Maternal schooling was the most consistent constraint to all three categories of childcare practices namely child feeding, health seeking, and hygiene practices in Accra.  The first two indices were based on data from maternal recall (with children under 3 years of age). The traditional child-feeding practices included breastfeeding, use of prelacteal feedings, and timing of introduction of complementary liquids and foods in the child's diet. The preventive health seeking behaviors included attendance at growth monitoring and whether the child had been immunized. This index seemed to be a very useful tool for examining associations between childcare and nutritional status.  The hygiene index was based on spot-check observations of proxies for hygiene behaviors. A positive relationship between the child rearing knowledge and child rearing practice was observed in the pilot study. 
Ruel and Menon created a child-feeding index including the dimensions of breastfeeding practices, dietary diversity, food frequency, and meal frequency based on DHS data sets from five Latin American countries  and the results showed a significant association between the child-feeding index and child-nutritional status. Nevertheless, this composite feeding index was not associated with physical growth among the rural African children.  The NFHS-2 data set does provide child feeding information, but not in sufficient detail to prepare such an indicator.  A comparison of the available child feeding scales is given in [Table 5].
The instruments CRKS and CRPS can be used to assess the child rearing knowledge and practices of normal women and women with special problems such as epilepsy. All items in the scales are worded in easy to understand language and are not focused on any particular disease. The scales are easy to administer and can even measure change in knowledge that occurs during infancy. However, the correlation between CRK and CRP as well as Baby outcome needs further confirmation.
| Conclusion|| |
The CRKS and CRPS were found to be valid reliable instruments to measure maternal child rearing knowledge and practices of women with epilepsy. These scales have potential application in clinical research.
What is already known
Comprehensive scales to measure child rearing knowledge and practices of mothers with infants are not available.
What this study adds
We have validated a new set of instruments to evaluate the child rearing knowledge and practice under the four major domains of child rearing: feeding, meeting the needs of cleaning, and protection including prevention of accidents and injuries, providing appropriate infant stimulation, and monitoring growth and development.
