This study sought to develop the Breastfeeding Adaptation Scale-Short Form(BFAS-SF) for use at 4 weeks postpartum, to test its validity and reliability, and to examine its measurement invariance. The latent mean score of the BFAS-SF across multiple groups was also compared.
This methodological research study was conducted to develop a short form of the BFAS and to test its psychometric properties and measurement invariance. Data were collected twice for measurement invariance testing. The sample included 431 and 272 breastfeeding mothers at 2 weeks and 4 weeks postpartum, respectively.
Confirmatory factor analysis supported six dimensions of the BFAS-SF at 4 weeks postpartum. Multi-group confirmatory factor analysis revealed evidence for invariance of the BFAS-SF according to employment status, parity, delivery mode, and the postpartum period. There were statistically significant latent mean differences. Mothers who were unemployed and who had a vaginal delivery showed significantly higher scores for breastfeeding confidence, sufficient breast milk, and baby’s satisfaction with breastfeeding.
The BFAS-SF is valid, reliable, and an appropriate instrument for assessing mothers’ breastfeeding adaptation. It can be used to compare mean scores according to employment status and delivery mode.
New mothers in Korea convalesce and adapt to motherhood for roughly 4.6 weeks at a combination of postpartum care centers (75.1%), their own homes (70.2%), their parents’ homes (19.8%), or their in-laws’ homes (2.4%) after being discharged from the hospital 3~5 days post-childbirth [
The BFAS was developed by defining the concept of adaptation to breastfeeding based on Roy’s four modes of adaptation through a review of the literature on breastfeeding, existing tools for assessing breastfeeding, and an analysis of interviews with breastfeeding mothers and clinical nurses [
The original scale is applicable to breastfeeding women at 4 weeks from childbirth, known as the period of adjustment to breastfeeding [
It takes 2~6 weeks after childbirth for the mother to get acquainted with her baby, learn about her newborn, and physically recover, and 2 weeks to 4 months to move toward a new normal [
The MI of a scale is essential for comparing the scores of variables across multiple groups defined according to different characteristics (age, gender, time point, etc.). The measurement scores between two groups can be compared more stably if consistency is present in the types of factors of the scale measuring a certain concept and each factor’s indicator variables, factor load, intercept, variance and covariance, and error variance [
Therefore, this study presents the development of an abbreviated version of the BFAS (yielding the Breastfeeding Adaptation Scale-Short Form, or BFAS-SF), confirmation of its validity and reliability, and suggestions regarding the applicability of the BFAS-SF. Additionally, by measuring the MI of the BFAS-SF at 4 weeks postpartum, this study derived implications regarding future breastfeeding adaptation assessment. Furthermore, the latent variable means of the BFAS-SF were calculated and presented.
This study was conducted to develop the BFAS-SF, to assess its validity and reliability, and to verify the MI of the scale and differences in adaptation to breastfeeding. First, construct validity and internal consistency reliability of BFAS-SF at 4 weeks postpartum were verified. Second, the MI of the BFAS-SF was verified depending on the mother’s employment status, parity, and delivery mode at 4 weeks postpartum and according to length of postpartum period (2 vs 4 weeks). Third, if any intercept invariance according to employment status, parity, delivery mode, and length of postpartum period was found, between-group differences in the latent variable means of the BFAS-SF were confirmed.
This is a methodological research study conducted to develop a short form of the BFAS (the BFAS-SF) and to test its validity, reliability, and MI.
The target group comprised breastfeeding Korean women at 2 weeks postpartum (14~20 days) who voluntarily participated in the survey. These new mothers and babies had not been hospitalized for any disease after birth. The 4-week postpartum group comprised breastfeeding women who participated in the study by responding to the first survey.
For confirmatory factor analysis of the BFAS-SF, the minimum sample size was 109 individuals (Cronbach’s ⍺ was .05, degrees of freedom=296, power=.90, null root mean square error of approximation [RMSEA]=.00, and alternative RMSEA=.05) [
Breastfeeding adaptation was measured using the BFAS [
Data for this study were collected from December 15, 2017 to May 31, 2018. Data for the first survey at 2 weeks postpartum were collected through convenience sampling at 10 postpartum care centers in Seoul, Daegu, Gwangju, Busan, and Gyeongsang Province. As outsiders are not allowed to enter postpartum care centers to keep infants safe from infection, the researcher hired an employee at each postpartum care center as a research assistant. The assistants provided an oral explanation on the study to the subjects at 2 weeks postpartum, and then distributed the questionnaires to those who agreed to take part in the study and collected their responses upon completion. Small gifts (5,000 Korean won) were given to the participants to express gratitude. In the first survey, the questionnaire gathered information on sociodemographic characteristics, obstetric characteristics, and breastfeeding adaptation.
The second survey was distributed online through social networking services or e-mail to those who agreed to data collection at 4 weeks postpartum and provided their phone number or e-mail address directly. The second survey reexamined the current health status of the baby and breastfeeding adaptation in mothers.
Values for the frequency and percentage of the subjects’ demographic characteristics were calculated, and the mean, standard deviation, skewness, and kurtosis of items and factors were assessed using SPSS version 25.0 (IBM Corp., Armonk, NY, USA). Cronbach’s ⍺ and 95% confidence intervals (CIs) were obtained to assess internal consistency reliability.
To verify construct validity, confirmatory factor analysis was performed using AMOS version 25.0 (IBM Corp., Armonk, NY, USA). The following goodness-of-fit indices were used to evaluate the fit of the models: chi-square (
Tests of the MI between the two groups according to employment status, parity, delivery mode, and the postpartum period were performed using the BFAS-SF. The test of the MI involved five steps. The first step was configural invariance (factor structure), the second step was metric invariance (factor loading invariance), the third scalar invariance (intercept invariance), the fourth step was factor variance invariance and factor covariance invariance, and the fifth step was error variance invariance. When MI was rejected at each step, partial MI was confirmed. A change in the model fit in MI testing is generally indicated by an increased
When the scalar invariance was verified, the group mean differences in latent variables were tested.
All data were collected after Institutional Review Board (IRB) approval (approval number: CUIRB-2017-0079). The purpose of the study, data collection procedure, confidentiality and anonymity, and possibility of withdrawal were explained to the 2-week postpartum participants. An explanation was also given of the data processing procedure, in which data were encrypted, stored separately on a storage device, and completely deleted after the end of the study. The plan to conduct additional data collection at 4 weeks after birth was explained. Participants voluntarily signed an agreement to participate.
The general background characteristics of participants at 2 and 4 weeks postpartum are described in
Confirmatory factor analysis was conducted on the 27 items and eight factors of the BFAS. The fit of the model was unacceptable:
Upon verifying the convergent validity of the BFAS-SF, the CR of each factor was ≥.73; each AVE was also ≥.57. After examining the discriminative validity of the factors, the correlation coefficient between factors was found to be .25~.68, and the AVE values of all the latent variables were greater than the square of the correlation coefficient between the latent variables.
The names of the sub-dimensions of the BFAS-SF are as follows: factor 1, emotional exchange with one’s baby; factor 2, breastfeeding confidence; factor 3, sufficient breast milk; factor 4, baby’s feeding capability; factor 5, baby’s satisfaction with breastfeeding; factor 6, maintenance of breast milk volume.
The M±SD, skewness, and kurtosis of the items and M±SD of factors of the BFAS-SF are shown in
Cronbach’s ⍺ (95% CI) for the overall scale was .88 (.85~.90). The Cronbach’s ⍺ values were as follows for the sub-dimensions: factor 1, .84 (.80~.87); factor 2, .67 (.59~.73); factor 3, .78 (.73~.82); factor 4, .75 (.69~.81); factor 5, .79 (.74~.84); factor 6, .75 (.68~.80) (
In MI testing of the BFAS-SF according to mother’s employment status (being employed or not), the fit indexes were acceptable for configural (factor structure) invariance. Although metric invariance was not supported (with a △CFI>.005), partial metric invariance, partial scalar invariance, partial factor variance (covariance), and partial error variance invariance were achieved (with a △CFI≤.005 and a △RMSEA≤.0100), with 15 indicators (except for item no. 25, ‘trying to eat enough food and water for breastfeeding’) having equal factor loadings, item intercepts, factor variance (covariance), and error variance across groups (
In MI testing of the BFAS-SF across parity (primipara or multipara), configural and metric invariance were achieved (with a △CFI≤.005, a △RMSEA≤.010, and a △SRMR≤.0250), with all indicators having equal factor structure and factor loadings (
In MI testing of the BFAS-SF across delivery mode (vaginal or cesarean delivery), configural, metric, and scalar invariance were achieved (with a △CFI≤.005, a △RMSEA≤.010, a △SRMR≤.0050), with all indicators having equal factor structure, factor loadings, and item intercepts across groups (
The longitudinal MI of the BFAS-SF at 2 and 4 weeks postpartum was examined. The fit indexes were acceptable for configural (factor structure) invariance. Although metric invariance was not supported (with a △CFI>.005), partial metric invariance was achieved (with a △CFI≤.005, a △RMSEA ≤.010, a △SRMR≤.0250), with 14 indicators (except for item no. 1, ‘my baby looks so lovely when he or she is drinking breast milk,’ and item no. 12, ‘my breasts feel full when it is time to feed my baby’) having equal factor loadings and item intercepts across groups (
At 4 weeks postpartum, mothers who were unemployed had a 0.28-point higher (
Mothers who gave birth vaginally had a 0.24-point higher (
This study presented a shortened version of the BFAS that was derived by reexamining the key items and factors on adaptation to breastfeeding and verified its construct validity by conducting confirmatory factor analysis. The results showed acceptable convergent validity and discriminative validity for each factor. The internal consistency reliability of all items of the shortened scale was good (≥.80). The internal consistency reliability of the sub-dimensions was acceptable (≥.70), except for confidence in breastfeeding. The BFAS-SF may be valid and reliable for measuring mothers’ adaptation to breastfeeding at 4 weeks postpartum. Cronbach’s ⍺ of the overall scale of BFAS-SF and of its sub-dimensions showed improvement relative to the BFAS. Additionally, the BFAS-SF could be used to assess mothers’ breastfeeding adaptation using a subset of core items from the BFAS. Unlike a breastfeeding effectiveness scale recently developed in Korea, the BFAS-SF regards breastfeeding in postpartum care as an adaptation process and measures the adaptation that develops over time [
Regarding the items of the BFAS-SF, two items about the baby’s growth (baby’s health skin condition and weight gain) were deleted from the fourth factor of the original scale dealing with “the baby’s feeding capability and growth”, leaving the items about baby’s feeding capability (latching, rhythmic sucking/swallowing patterns) because new mothers generally cannot identify or interpret slight differences in the baby’s skin condition and weight gain at 2 and 4 weeks postpartum, whereas it is easier for them to recognize the feeding capability of their babies. Numerous scales exist for measuring babies’ feeding capability [
All three items about wounds and pain of the nipple and fatigue in the original factor “discomfort in breastfeeding” were deleted in the BFAS-SF. The scales currently used to measure discomfort in breastfeeding women in postpartum hospitals within the admission period [
The eighth factor, “getting support”, was deleted from the BFAS-SF. If a mother has successfully adapted to breastfeeding, she should be capable of breastfeeding without support. This factor had the lowest explained variance and internal consistency reliability during development [
MI (cross validity) was confirmed as part of verifying the validity of BFAS-SF. Strict MI of the BFAS-SF was achieved, except for item no. 25 (trying to eat enough food and water for breastfeeding) between the groups divided by employment status. The reason why the MI of item no. 25 was not established may be interpreted in terms of the influence of returning to work. In other words, because of the clear correlation between proper food intake and breast milk production [
This study verified the configural and metric invariance of the BFAS-SF between primiparous and multiparous groups. It was also found that equivalence could not be ensured due to the large difference in the intercepts for many items on adaptation to breastfeeding between the groups. The difference in the intercepts between primiparous and multiparous mothers may be explained by differences in readiness due to breastfeeding experience. That is, maternal stress is negatively correlated with breast milk production and ejection reflex [
Strict measurement equivalence between vaginal and cesarean delivery groups at 4 weeks postpartum was achieved. The effects of the delivery mode on breastfeeding adaptation are estimated to be insignificant at 4 weeks after delivery. Therefore, in future studies, it may be possible to compare the mean scores of the sub-dimensions of the BFAS-SF between mothers who underwent vaginal and cesarean delivery.
Metric invariance in the longitudinal MI of the BFAS-SF between 2 and 4 weeks postpartum was established for all items except item no. 1 (my baby looks so lovely when he or she is drinking breast milk) and no.12 (my breasts feel full when it is time to feed my baby). This indicates a difference in the factor loading between the two groups for these two items, with the mothers at 4 weeks postpartum being more likely to be attached to their baby than the mothers at 2 weeks because the former group has interacted with their baby for longer. Breast milk matures in roughly 10 days postpartum, after which the preset milk production is maintained at a steady rate and adjusted through an autocrine mechanism in which the law of milk supply responds to demand [
In this study, unemployed mothers had higher latent mean values of confidence in breastfeeding, sufficient breast milk, and baby’s satisfaction with breastfeeding than those who were employed. Women who were unemployed engaged in breastfeeding more often than women who were employed, and women who engaged in exclusive breastfeeding had higher self-confidence [
Mothers who gave birth vaginally had higher latent means for confidence in breastfeeding, sufficient breast milk, and their baby’s satisfaction with breastfeeding than those who had a cesarean section. Mothers who give birth vaginally have a more advantageous start in breastfeeding than those who have a cesarean delivery. At 24 hours postpartum, levels of prolactin and oxytocin in sera of mothers who underwent a cesarean section under general anesthesia were lower than those who had a vaginal birth [
Adaptation to breastfeeding is crucial for the health of both the mother and baby. Individualized nursing interventions can improve the long-term breastfeeding rate of mothers after assessing their adaptation to breastfeeding at 2 and 4 weeks postpartum. Nurses at hospitals and community health centers can develop programs to improve mothers’ adaptation to breastfeeding and assess the effects of such programs using the BFAS-SF.
Despite the difficulty in collecting data from new mothers due to the ultra-low birth rate in Korea, an attempt was made to gather data from new mothers at multiple institutions in various regions of the country to ensure the representativeness of the data. Nonetheless, the data were collected through convenience sampling from four cities and one province, and only mothers using postpartum care centers were investigated. The results of this study therefore may not represent the entire population of mothers who have recently given birth in Korea, and cannot be generalized because this study did not include data from new mothers who did not stay at a postpartum care center. Moreover, this study assessed the construct validity, reliability, and MI of the BFAS-SF among mothers at 4 weeks postpartum, but not the criterion-related validity, which should be assessed in further studies. The findings on the psychometric properties of the BFAS-SF at 2 weeks postpartum that were not reported in this article will be presented in subsequent paper.
This study presented the BFAS-SF, a shortened version of the BFAS that reduced the original 27 questions to 16 questions, and verified the construct validity, MI, and reliability at 4 weeks postpartum. The six sub-dimensions of the BFAS-SF consisted of emotional exchange with one's baby, breastfeeding confidence, sufficient breast milk, baby's feeding capability, baby's satisfaction with breastfeeding, and maintenance of breast milk volume. The BFAS-SF was found to be a valid and reliable tool applicable to new mothers. The MI among multiple was examined according to employment status, parity, delivery mode, and postpartum period, and suggestions were made regarding comparison and analysis of adaptation to breastfeeding. In future studies, careful interpretation of differences in item scores according to employment status and mean comparisons of the sub-dimensions is required. It is possible to compare differences in item scores both between parity groups and between postpartum period groups, but the degree to which mean values of the sub-dimensions of the BFAS-SF can be compared is limited. It is also possible to compare mean values of the sub-dimensions of the BFAS-SF among delivery modes. This scale will hopefully be used to assess adaptation to breastfeeding and the effects of related programs.
