Psychometric properties of the modified breastfeeding self-efficacy scale-short form (BSES-SF) among Chinese mothers of preterm infants.

Preterm mother-infant dyads face more challenges than healthy term infants in breastfeeding initiation and continuation due to maternal health status, preterm infant's immaturity or comorbidities, and breastfeeding policy of the neonatal units. Breastfeeding self-efficacy affects breastfeeding outcomes in preterm infants. No specific instrument in Chinese is available to assess maternal breastfeeding self-efficacy of preterm infants. This study aims to assess the psychometric characteristics of the modified Breastfeeding Self-Efficacy Scale-Short Form (BSES-SF) among Chinese mothers of preterm infants. A cross-sectional study was conducted. Two tertiary hospitals in China. A total of 153 women who gave birth before 37 weeks of gestation. The instrument was translated and back translated. The internal consistency reliability was investigated using Cronbach's alpha coefficient. The content validity, construct validity, and criterion validity were conducted to evaluate the validity of the scale. Exploratory factor analysis was used to investigate the factor structure. The scale had good reliability with Cronbach´s alpha above the acceptable level of 0.7. The Item-Content Validity Index (I-CVI) ranged from 0.800 to 1.000, and the Scale-Content Validity Index (S-CVI) is 0.950. The principal component analysis revealed the presence of two factors with eigenvalues greater than 1, explaining a total variance of 74.665%. The modified BSES-SF scores were correlated with women's parity, breastfeeding knowledge, previous breastfeeding experience, perceived support from the spouse and health professionals, and amounts of expressed milk. The Chinese version of modified BSES-SF is a reliable, valid screening instrument to evaluate the maternal breastfeeding self-efficacy of preterm infants. It is recommended to provide interactive, face-to-face breasting education and support to help mothers of preterm infants maintain high level of breastfeeding self-efficacy and further to achieve satisfactory breastfeeding outcomes.

Psychometric testing of the modified breastfeeding self-efficacy scale (short form) among mothers of ill or preterm infants.

To psychometrically assess the modified Breastfeeding Self-Efficacy Scale-Short Form (BSES-SF) among mothers of ill or preterm infants. Methodological study. Three neonatal intensive care units (NICUs) located in two hospitals in a central Canadian city. One hundred forty-four (144) breastfeeding mothers of ill or preterm infants. Mothers completed the BSES-SF modified for mothers of ill or preterm infants, the Hill and Humenick (H&H) Lactation Scale, and demographic questions. The Cronbach's alpha coefficient for internal consistency for the BSES-SF revised for mothers of ill or preterm infants was 0.88. Construct validity was assessed using comparison of contrasted groups (mothers who continued to breastfeed and those who discontinued) and correlation with the construct of maternal perceptions of insufficient milk supply. Support for predictive validity was demonstrated through significant mean differences between mothers who were breastfeeding (M = 83.44, SD = 8.23) and those who discontinued breastfeeding and breast pumping (M = 75.51, SD = 10.08) at 6-weeks post-infant hospital discharge. Demographic response patterns suggest that the modified BSES-SF is a unique tool to identify breastfeeding mothers of ill or preterm infants at risk of prematurely discontinuing. This study provides evidence that the modified BSES-SF may be a valid and reliable measure of breastfeeding self-efficacy among a sample of mothers of ill or preterm infants.

The Spanish version of the Breastfeeding Self-Efficacy Scale-Short Form: reliability and validity assessment.

Only a minority of infants are exclusively breastfed for the recommended 6 months postpartum. Breastfeeding self-efficacy is a mother's confidence in her ability to breastfeed and is highly predictive of breastfeeding behaviors. The Breastfeeding Self-Efficacy Scale-Short Form (BSES-SF) was developed among English-speaking mothers to measure breastfeeding self-efficacy. To translate the BSES-SF into Spanish and assess its psychometric properties. Methodological study. One public hospital in Orihuela, Spain. A convenience sample of 135 in-hospital breastfeeding women was recruited on their second day postpartum. The BSES-SF was translated into Spanish using forward translation, back-translation and pilot testing. Internal consistency, construct validity and predictive validity were assessed. A battery of self-report questionnaires was administered on the second day postpartum including: a questionnaire on sociodemographic variables and breastfeeding status, the translated BSES-SF, the Spanish adaptation of the General Self-Efficacy Scale and the Stress Management Self-Efficacy Scale. Also, data on breastfeeding status at three weeks postpartum were collected by telephone interviews. The Cronbach's alpha coefficient for internal consistency was 0.92. The translated BSES-SF presented a unidimensional structure with factor loadings of >0.30. In addition, demographic response patterns and correlations with self-efficacy scales provided further evidence of construct validity. In-hospital BSES-SF scores significantly predicted exclusive breastfeeding at 3 weeks postpartum. The results of this study indicate that the Spanish translation of the BSES-SF can be considered a valid and reliable measure of maternal breastfeeding self-efficacy in Spain.

Validity and reliability of the Turkish version of the paternal breastfeeding self-efficacy scale - Short form for fathers.

Women supported by their partners are more likely to initiate and maintain breastfeeding and overcome related challenges. Therefore, reliable measurement tools are needed to determine whether fathers can provide this support. This study aimed to (1) examine the psychometric properties of the Paternal Breastfeeding Self-Efficacy Scale-Short Form (BSES-SF) in Turkish fathers, including internal consistency reliability, test-retest reliability, construct validity using Confirmatory Factor Analysis (CFA); and (2) assess the relationship between the BSES-SF and paternal demographic factors. A methodologically study was conducted between December 26-2018 and June 26-2019 at the pediatrics clinics of two research hospitals of medical schools in Konya, Turkey. The sample consisted of 221 fathers of infants aged 2 to 6 weeks who visited the clinics for routine examinations. Data were collected using a sociodemographic questionnaire and the Turkish version of the Paternal BSES-SF. After evaluating the language equivalence and content validity of the scale, test-retest reliability, internal consistency and construct validity were examined. In evaluation of the data frequency/percentage, mean, standard deviation, independent groups t test, ANOVA Analysis, Bartlett's Test of Sphericity, Confirmatory Factor Analysis, Pearson Product-Moment correlation and Cronbach α analysis were used. The study was approved by Interventional Clinical Research Ethics Committee of the Faculty of Health Sciences of Selcuk University in Turkey. The translated Paternal BSES-SF had a Cronbach's alpha of 0.93 and a test-retest reliability coefficient of 0.96. The factor loadings ranged from 0.42 to 0.76. The Paternal BSES-SF had a one-factor structure similar to the original scale. Fathers who were unemployed, had lower economic status, and unplanned pregnancy had significantly lower mean Paternal BSES-SF scores. Paternal education regarding breastfeeding increased mean Paternal BSES-SF retest scores (p<0.05). The Paternal BSES-SF was a valid and reliable measure to assess fathers' confidence in their ability to assist mothers with breastfeeding in Turkey. Turkish researchers and health workers can use this instrument as a reference for promoting exclusive breastfeeding.
