Psychometric properties of the Breastfeeding Self-Efficacy Scale-Short Form in an ethnically diverse U.K. sample

ABSTRACT Objective: To psychometrically assess the Breastfeeding Self-Efficacy Scale-Short Form (BSES-SF) among a multicultural U.K. sample and to examine the relationship between breastfeeding self-efficacy and maternal demographic variables.
Design: A cohort study where breastfeeding women completed questionnaires in-hospital and at 4 weeks postpartum.
Sample: 165 breastfeeding women at the maternity ward in Birmingham Women's Hospital inpatient department.
Measurements: BSES-SF.
Results: The Cronbach's α co-efficient was .90 and evidence for predictive validity was demonstrated through exclusively breastfeeding mothers at 4 weeks postpartum having significantly higher in-hospital BSES-SF scores ( M =49.4, SD =12.9) than mothers who were partially breastfeeding ( M =44.7, SD =9.5) or bottle-feeding, M =42.4, SD =11.7; F (2)=1.62, p <.001. Caucasian mothers had significantly lower mean scores ( M =44.4, SD =12.1) than those of other ethnicity, M =48.4, SD =12.9, t (163)=−2.06, p =.04.
Conclusions: This study builds upon previous research and provides additional evidence suggesting that the BSES-SF has sound psychometric properties and can be utilized among diverse samples, including Southeast Asian mothers.     

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

BackgroundOnly 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.ObjectivesTo translate the BSES-SF into Spanish and assess its psychometric properties.DesignMethodological study.SettingOne public hospital in Orihuela, Spain.ParticipantsA convenience sample of 135 in-hospital breastfeeding women was recruited on their second day postpartum.MethodsThe 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.ResultsThe 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.ConclusionsThe 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.     

A Chinese version of Iowa Infant Feeding Attitude Scale: reliability and validity assessment

Background

To achieve the goal of increasing the proportion and duration of breastfeeding in Taiwan, it is essential to assess the role of attitudes in determining which method of infant feeding will be chosen. Understanding maternal attitudes toward infant feeding methods may have utility in the development and implementation of public health policy and interventions facilitating increasing breastfeeding rates. However, no validated instrument to assess breastfeeding attitudes is available in Chinese for use in Taiwan.

Objective

To translate the Iowa Infant Feeding Attitude Scale (IIFAS) into Chinese and assess its psychometric properties among Taiwanese breastfeeding women.

Design

Methodological study.

Setting

One public hospital in Taichung city, Taiwan.

Participants

A convenience sample of 140 in-hospital breastfeeding women was recruited.

Methods

The IIFAS was translated into Chinese using forward translation, back-translation, semantic equivalence, and pilot testing. Predict validity and internal consistency was assessed. The final sample consisted of 120 women (14% attrition) that were interviewed by telephone at 6 weeks postpartum to record the breastfeeding duration and infant feeding method.

Results

One item was modified to better reflect the item content. In-hospital IIFAS scores significantly predicted breastfeeding duration as well as exclusive breastfeeding at 6 weeks postpartum. The Cronbach's alpha coefficient for internal consistency was 0.74.

Conclusions

This study provides evidence that the Chinese version of the IIFAS can be considered valid and reliable scale for assessing attitudes toward breastfeeding among breastfeeding women in Taiwan.

The Spanish version of the Prenatal Breast-feeding Self-efficacy Scale: Reliability and validity assessment

Background

Only a minority of infants are exclusively breastfed for the recommended 6 months postpartum. Breast-feeding self-efficacy is a mother's confidence in her ability to breastfeed and is predictive of breastfeeding behaviors. The Prenatal Breast-feeding Self-efficacy Scale (PBSES) was developed among English-speaking mothers to measure breastfeeding self-efficacy before delivery.

Objectives

To translate the PBSES into Spanish and assess its psychometric properties.

Design

Reliability and validity assessment.

Setting

A public hospital in Yecla, Spain.

Participants

A convenience sample of 234 pregnant women in their third trimester of pregnancy.

Methods

The PBSES was translated into Spanish using forward and back translation. A battery of self-administered questionnaires was completed by participants, including a questionnaire on sociodemographic variables, breastfeeding experience and intention, as well as the Spanish version of the PBSES. Also, data on exclusive breastfeeding at discharge were collected from hospital database. Dimensional structure, internal consistency and construct validity of the Spanish version of PBSES were assessed.

Results

Confirmatory factor analysis suggested the presence of one construct, self-efficacy, with four dimensions or latent variables. Cronbach's alpha coefficient for internal consistency was 0.91. Response patterns based on decision to breastfeed during pregnancy provided evidence of construct validity. In addition, the scores of the Spanish version of the PBSES significantly predicted exclusive breastfeeding at discharge.

Conclusions

The Spanish version of PBSES shows evidences of reliability, and contrasting group and predictive validity. Confirmatory factor analysis indicated marginal fit and further studies are needed to provide new evidence on the structure of the scale. The Spanish version of the PBSES can be considered a reliable measure and shows validity evidences.     

The Persian version of Trinity Amputation and Prosthetics Experience Scale: translation,factor structure,reliability and validity

Purpose.?The purpose of the present study was to translate the Trinity Amputation and Prosthetics Experience Scale (TAPES) into Persian and to investigate its psychometric properties.

Method.?A sample of 182 Persian-speaker individuals with lower limb amputation completed the TAPES questionnaire, of whom 103 individuals completed the Short Form 36 Health survey as well. The TAPES was re-administered to 41 participants in the retest session, with an interval of 5–7 days between the two sessions. Internal consistency, test-retest reproducibility, dimensionality, item internal consistency and discriminant validity and construct validity were assessed.

Results.?Cronbach's α's were greater than the cut-off point of 0.70 for all subscales with the exception of social adjustment subscale. Minimum intraclass correlation coefficient of 0.70 was exceeded by all subscales with the exception of social activity subscale. Principle component analysis performed on each section of the TAPES revealed loading of all items on their corresponding factors. The exceptions were item 4 of social adjustment subscale and the single item of weight subscale. Most items were stronger measures of their hypothesised subscale than the other subscales. In terms of construct validity, 75%% of a priori hypotheses were confirmed.

Conclusions.?The Persian version of TAPES seems to be a reliable and valid measure of psychological adaptation to artificial limb.

Assessing the reliability and validity of the Chinese version of the California Critical Thinking Disposition Inventory.

The purpose of this study was to: (1) translate the California Critical Thinking Disposition Inventory (CCTDI) from English to Chinese; (2) ascertain the reliability and validity of Chinese CCTDI; and (3) assess the psychometric equivalencies across Chinese and English versions of the CCTDI. The CCTDI was designed to measure critical thinking dispositions of truth-seeking, open-mindedness, analyticity, systematicity, inquisitiveness, self-confidence and maturity, which has been approved with a significant difference from prior conceptualizations of critical thinking dispositions. It is the only measurement that has been validated to measure critical thinking disposition and is appropriate for use in nursing. Based on translation theory, the comparative study goal precisely matched with the strategy of decentered translation. The CCTDI was translated in multiple stages and back translated by a panel of bilingual experts. Content validity index (CVI) ranged from 0.50 to 0.80, with an overall CVI of 0.85. Pearson r ranged from 0.33 to 0.79, with an overall correlation of 0.79, indicating that evidence for stability in truth-seeking, open-mindedness and self-confidence existed. To ascertain internal consistency reliability and construct validity, monolingual samples were obtained from 214 and 196 undergraduate nursing students from Taiwan and the USA, respectively. For the Chinese CCTDI, subscale alphas ranged from 0.34 to 0.73, with an overall alpha of 0.71. For the English CCTDI, subscale alphas ranging from 0.52 to 0.73 and an overall alpha of 0.71 were obtained. In terms of a confirmatory factor analysis with LInear Structural RELationships (LISREL), the results indicate that evidence for construct validity existed for truth-seeking, open-mindedness, systematicity, and maturity for the Chinese CCTDI. After allowing some error to exist and deleting three items, evidence for construct validity existed for the remaining subscales. The results of the psychometric equivalencies across Chinese and English CCTDI showed similarity for content validity and reliability for inquisitiveness. In terms of multisample analysis, there were equal forms across all subscales of the two versions. Consequently, although the translation adequacy of the Chinese CCTDI needs to be improved, there is evidence that it is useful for evaluating critical thinking dispositions.
