Psychometric Properties of the Spanish Version of the Iowa Infant Feeding Attitude Scale in Fathers.

BACKGROUND: Research gaps exist with regard to paternal attitudes towards breastfeeding and the association between fathers' attitudes and the type of breastfeeding. RESEARCH AIMS: (1): To analyze the psychometric properties of the Spanish version of the Iowa Infant Feeding Attitude Scale in fathers, and (2) to examine the association between fathers' attitudes and type of breastfeeding. METHOD: We used a cross-sectional study design to analyze the scale's psychometric properties and performance. RESULTS: A total of 639 fathers participated in the study. The mean age was 35.83 years (SD = 4.65) and 67.3% (n = 430) were married or in a civil partnership. We observed an adequate fit in the confirmatory factor analysis: TLI = 0.96, CFI = 0.97 and RMSEA = 0.05. The overall internal consistency was 0.76. Between 1-6 months, 48% (n = 307) of participants' babies were exclusively breastfed, 35.2% (n = 225) were partially breastfed, and 16.7% (n = 107) were exclusively formula fed. Statistically significant differences were shown in attitudes towards breastfeeding, depending on the type of breastfeeding, between 1 and 6 months (F = 54.67; p < .001). Fathers who reported that their baby had been exclusively breastfed scored higher on attitudes towards breastfeeding. Statistically significant differences were also found between partial breastfeeding and formula feeding. CONCLUSIONS: The Spanish version of the Iowa Infant Feeding Attitude Scale is a valid and reliable instrument for measuring paternal attitudes towards breastfeeding.

A Survey of Breastfeeding Attitudes and Health Locus of Control in the Nigerian Population.

OBJECTIVES: Breastfeeding is important to infant health and survival in sub-Saharan Africa. To promote breastfeeding effectively, understanding of psychological factors associated with infant feeding choices is required. This study investigated breastfeeding attitudes and health locus of control (HLoC) in a Nigerian community sample. METHODS: Men and women (N = 400) (71% female; mean age 34.2 years/ range 18-86 years) were recruited through community groups in Nigeria. Self-report survey by questionnaire measured breastfeeding attitudes using the Iowa Infant Feeding Attitude Scale (IIFAS) and health locus of control using the Multidimensional Health Locus of Control Scale (MHLoCs). RESULTS MEAN: IIFAS scores (mean = 57.7; sd = 7.8) became less favourable with increasing age (p = 0.02). Men had higher IIFAS scores (mean = 58.6; sd = 7.6) than women (mean = 56.6; sd = 8.0) indicating more favourable attitudes toward breastfeeding (p = 0.02). Women scored higher than men on external chance HLoC (ECHLoC) (p = 0.003) and external powerful others HLoC (EPHLoC) (p = 0.02). Increasing age was associated with higher scores on ECHLoC (p < 0.01) and EPHLoC (p < 0.01). Multiple linear regression analysis was significant (p < 0.001) and explained 7.8% of variance in breastfeeding attitude. Lower IIFAS scores, reflecting more negative attitudes to breastfeeding, were associated with higher ECHLoC (p < 0.01) and EPOHLoC (p < 0.05). Higher IIFAS scores, reflecting more positive attitudes to breastfeeding, were associated with greater IHLoC (p < 0.01). Neither age nor gender were associated with IIFAS scores in the final model. CONCLUSIONS: This implies a need to explore health locus of control when promoting positive attitudes to breastfeeding and supporting families in breastfeeding advocacy.

SIGNIFICANCE: What is already known? Infant feeding decisions are made in a social context and influenced by significant others. Yet, most studies of breastfeeding attitudes have exclusively considered women of childbearing age and mostly in Western cultures. What this study adds? This study meets a need to understand societal attitudes to breastfeeding in diverse cultures. The research also tests the theory that health-related locus of control (H-RLoC) will be related to breastfeeding attitudes. Knowledge of societal attitudes toward breastfeeding and of HRLoC will help to inform effective breastfeeding promotions that are tailored to the specific needs of Nigerian people.

Muslim women's attitudes toward infant feeding in Qatar: An exploration using the Iowa infant feeding attitude scale.

BACKGROUND: Maternal attitude toward infant feeding is an important determinant of breastfeeding. The Islamic faith encourages breastfeeding, yet many Muslim women do not breastfeed as per the World Health Organization recommendations. In the Middle East, research has not addressed attitudes toward infant feeding among Muslim women. Assessing women's attitudes toward infant feeding choices is crucial to improve breastfeeding rates among Muslim women. AIM: The aims of this study are to (a) examine postpartum Muslim women's attitudes toward infant feeding, (b) identify the determinants of these attitudes, and (c) determine whether attitudes can predict breastfeeding intention among Muslim women. A secondary aim is to examine the psychometric attributes of the Iowa Infant Feeding Attitude Scale among Muslim women. METHOD: A convenience sample of postpartum Muslim women (N = 414) were recruited between November 2019 and January 2020 in a large maternity facility in Qatar. A pre-developed questionnaire and the IIFAS were used to collect data. Both Arabic (n = 228) and English (n = 186) versions of the IIFAS were distributed postnatally to measure Muslim women's attitudes towards breastfeeding. A total attitude score was computed with higher scores indicating a more positive attitude toward breastfeeding. FINDINGS: The mean age of participants was 30.3 ± 5.2 years; 65.2% had a university degree and only 20.5% were employed. The mean attitude score was 61.8 ± 7.8. A significant association was found between the IIFAS attitude score and ethnicity, favouring Non-Qatari Arab women who had significantly higher attitude scores (p < .001). Women with full-time or part-time work had significantly higher scores than those not working (p = .008, p = .023). Older women had significantly lower attitude scores (adjusted slope = -0.230, p = .008). Cronbach's alpha reliability coefficient of the Arabic and English versions of the IIFAS ranged from 0.69 to 0.80. CONCLUSION: Ethnicity, employment status, and age are determinants of infant feeding attitudes among Muslim women. In Qatar, Muslim women's attitudes related to breastfeeding trend toward positive; however, attitude is not a predictor of antenatal breastfeeding intention. Further research employing a larger sample with a focus on a culturally sensitive approach is recommended. The IIFAS has a moderate reliability level and needs to be culturally adapted to be used among a Muslim population.

The Attitudes of Polish Women towards Breastfeeding Based on the Iowa Infant Feeding Attitude Scale (IIFAS).

BACKGROUND: The Iowa Infant Feeding Attitude Scale (IIFAS), which is used for the assessment of attitudes towards breastfeeding, has been found to be reliable and valid in a number of countries, but has not yet been psychometrically tested in Polish women. The purpose of the study was to report on the cultural adaptation of the IIFAS to Polish settings and on its validation, to evaluate the breastfeeding attitudes in Polish women who recently gave birth, and to identify the determinants of these attitudes. METHODS: The study was performed in a group of 401 women in their first postpartum days. RESULTS: Cronbach's α for the scale was 0.725. Discriminative power coefficients of all questionnaire items were higher than 0.2. Subscales were strongly correlated with the total score, with a correlation coefficient of 0.803 for the "favorable toward breastfeeding" subscale (p < 0.001), and 0.803 for the "favorable toward formula feeding" subscale (p < 0.05). For the item "A mother who occasionally drinks alcohol should not breastfeed her baby", the factor loading did not reach the criterion value, and so the item was not included in further analyses. The mean IIFAS score was 63.12 (±7.34). CONCLUSIONS: The Polish version of the IIFAS is a reliable and appropriate measure of women's attitudes towards infant feeding in Polish settings, with acceptable psychometric properties and construct validity.

Reliability and Validity of the Greek Version of the Iowa Infant Feeding Attitude Scale Among Pregnant Women.

INTRODUCTION: A modifiable factor related to breastfeeding is breastfeeding attitudes. The Iowa Infant Feeding Attitude Scale (IIFAS) is used to evaluate this factor. Although the breastfeeding rates in Greece are declined there is not available any validated instrument to evaluate infant feeding attitudes. AIM: to determine the psychometric properties of the Greek adaptation of the IIFAS in a sample of pregnant women. MATERIALS AND METHODS: Pregnant women (N=203) from a University Hospital in Athens, Greece, were administered the Greek version of the IIFAS, while being in hospital, and their infant feeding mode at six months postpartum was recorded by telephone. The reliability of the scale was assessed by using corrected item-total correlations and Cronbach's alpha. Construct validity of the scale was assessed by using confirmatory factor analysis and predictive validity by using t-tests. Multiple linear regression analyses in a stepwise method (p for removal was set at 0.1 and p for entry was set at .05) was performed in order to find variables independently associated with IIFAS total score. RESULTS: The mean IIFAS score was 70.0 (SD=7.6). The corrected item-total correlation ranged from 0.22 to 0.51. Cronbach's alpha was equal to 0.71. The confirmatory factor analysis indicated an adequate fit of the one-factor model. Concerning the predictive validity of IIFAS it was significant for breastfeeding at six months. The mean IIFAS score was significantly greater (p=0.001) for women that had exclusive breastfeeding at six months (mean (SD): 68.4(6.6)) as compared with those that did not (mean (SD): 64.0(7.5)). Higher IIFAS scores were found in older women, with higher educational level and in those that had breastfed children in their social environment. CONCLUSION: The Greek version of the IIFAS demonstrated satisfying reliability and validity for measuring women's infant feeding attitudes in the Greek context. Also, the results of the present study provide further evidence of the international applicability of the IIFAS.

Infant Feeding Attitudes and Practices of Spanish Low-Risk Expectant Women Using the IIFAS (Iowa Infant Feeding Attitude Scale).

The Iowa Infant Feeding Attitude Scale (IIFAS) has been shown to have good psychometric properties for English-speaking populations, but it has not been validated among low-risk pregnant women in Spain. The aim of this study was to assess the reliability and validity of the translated version of the IIFAS in order to examine infant feeding attitudes in Spanish women with an uncomplicated pregnancy. Low-risk expectant women (n = 297) were recruited from eight primary public health care centres in Galicia (Spain). Questionnaires including both socio-demographic and breastfeeding characteristics and items about infant feeding were administered during the third trimester. Participants were contacted by telephone during the postpartum period to obtain information regarding their infant feeding status. Prediction validity and internal consistency were assessed. The translated IIFAS (69.76 ± 7.75), which had good psychometric properties (Cronbach's alpha = 0.785; area under the curve (AUC) of the receiver operating characteristic (ROC) curve = 0.841, CI95% = 0.735⁻0.948), showed more positive attitudes towards breastfeeding than towards formula feeding, especially among mothers who intended to exclusively breastfeed. This scale was also useful for inferring the intent to breastfeed and duration of breastfeeding. This study provides evidence that the IIFAS is a reliable and valid tool for assessing infant feeding attitudes in Spanish women with an uncomplicated pregnancy.

Reliability and Validity of the Reduced Spanish Version of the Iowa Infant Feeding Attitude Scale.

OBJECTIVE: To translate the Iowa Infant Feeding Scale (IIFAS) into Spanish, to test its psychometric properties, and to explore item reduction for the Spanish version. DESIGN: Instrumental study. SETTING: Six hospitals in eastern Spain. PARTICIPANTS: A convenience sample of 1,354 pregnant women was recruited. METHODS: The IIFAS was translated using forward and back translation. Dimensional structure, internal consistency, and construct validity of the Spanish IIFAS version were assessed. Criteria to improve the reliability of the scale and the predictive power of the items were used to reduce the scale. RESULTS: Statistics on the psychometric properties suggested the need for item reduction. Cronbach's alpha coefficient of the nine-item final version of the Spanish IIFAS (IIFAS-S) was 0.792. The confirmatory factor analysis showed a unidimensional structure. Demographic response patterns and correlations with the IIFAS-S scale provided further evidence of construct validity. Pregnancy IIFAS-S scores significantly predicted breastfeeding rates and exclusivity. CONCLUSION: The results of this study indicated that the Spanish translation of the IIFAS is a valid and reliable measure of women's attitudes toward breastfeeding.

Psychometric Properties of the Iowa Infant Feeding Attitude Scale among a Multiethnic Population during Pregnancy.

BACKGROUND: The Iowa Infant Feeding Attitude Scale (IIFAS) was developed to measure maternal attitudes toward infant feeding, but a number of validated studies on the IIFAS found that it was subject to methodological limitations. OBJECTIVE: The purpose of this study was to evaluate the psychometric properties of the IIFAS among a multiethnic population in Singapore. METHODS: A cross-sectional research design was used on a sample of 417 antenatal women. The internal consistency and stability of the IIFAS were evaluated using Cronbach's α and test-retest reliability. Known-group comparisons discriminated certain group differences in a predictable way. A series of exploratory factor analyses (EFAs) was conducted to test the factor structure of the IIFAS using the maximum likelihood and principal axis factoring. The number of factors was selected according to theoretical and statistical considerations. A confirmatory factor analysis (CFA) was further performed to validate the factor structure constructed in the prior EFA. RESULTS: The IIFAS had a Cronbach's α and Pearson correlation of 0.79 and 0.85, respectively. The known-group comparisons among certain groups were supported. The EFA results showed that the 3-factor structure produced the most interpretable and theoretical sense. A second-order CFA was conducted to confirm the construct dimensionality of the 15-item IIFAS, with satisfactory fit indices found. CONCLUSION: The 15-item IIFAS is a psychometrically sound measurement tool that health care professionals can use to understand the diverse infant feeding attitudes and knowledge among different ethnic groups in order to provide breastfeeding interventions that are culturally sensitive.

A comparison of maternal attitudes to breastfeeding in public and the association with breastfeeding duration in four European countries: results of a cohort study.

BACKGROUND: There is wide variation in the duration of breastfeeding across Europe which may in part be due to the between-country differences in mothers' and societal attitudes towards breastfeeding in public. The objective of this study was to quantify and compare the maternal attitudes to, and practice of, breastfeeding in public in four European centers and investigate the association with duration of breastfeeding. METHODS: Participants (n = 389) were mothers recruited from maternity wards of hospitals in Glasgow (Scotland), Stockholm (Sweden), Granada (Spain), and Reggio-Emilia (Italy). RESULTS: Among those who had breastfed, Scottish (adjOR 0.25 [95% CI 0.12-0.50]) and Italian mothers (adjOR 0.30 [95% CI 0.14-0.63]) were significantly less likely than Swedish mothers to have ever breastfed in public. Mothers who had a negative attitude toward breastfeeding in public were less likely to have ever breastfed in public (adjOR 0.05 [95% CI 0.02-0.17]), and those who had never breastfed in public were in turn more likely to discontinue breastfeeding earlier. CONCLUSIONS: Perceived social norms may exert a stronger influence on breastfeeding outcomes than a woman's breastfeeding attitudes and knowledge. Differences between European countries in the duration of breastfeeding may be explained in part by differences in societal attitudes to breastfeeding in public.

Reliability and Validity of the Japanese Version of the Iowa Infant Feeding Attitude Scale: A Longitudinal Study.

BACKGROUND: The 17-item Iowa Infant Feeding Attitude Scale (IIFAS) has shown good reliability and validity to measure attitudes toward infant feeding in various countries. It is also known to be associated with breastfeeding intention and exclusivity. However, the IIFAS has not been psychometrically tested among Japanese women. OBJECTIVE: This study aimed to develop the Japanese version of the IIFAS (IIFAS-J) and assess its reliability and validity. METHODS: This longitudinal study was conducted with 781 women at 4 hospitals in Japan. The translated IIFAS was administered to participants during their third trimester. Infant feeding status was self-reported at 4 and 12 weeks postpartum using follow-up questionnaires. The predictive validity was determined by examining the association between the IIFAS-J score during pregnancy and infant feeding status at 4 and 12 weeks postpartum. RESULTS: One item was removed after a principal components analysis. Therefore, the IIFAS-J consisted of 16 items. Cronbach's alpha of the IIFAS-J was 0.66. A higher IIFAS-J score during the third trimester was associated with a higher postdischarge exclusive breastfeeding rate at 4 weeks postpartum (B = 0.05; adjusted odds ratio = 1.05; 95% confidence interval, 1.01-1.10). CONCLUSION: The 16-item Japanese version of the IIFAS is a reliable and valid scale for measuring maternal infant-feeding attitudes during pregnancy.

Predicting breastfeeding duration related to maternal attitudes in a taiwanese sample.

The purpose of this study was to examine maternal attitudes and sociodemographic variables associated with Taiwanese mothers' continuation of breastfeeding at 6 weeks postpartum. A sample of 140 in-hospital breastfeeding mothers was recruited in Taiwan. Participants completed the Iowa Infant Feeding Attitude Scale (IIFAS) in the hospital prior to discharge. Postdischarge participants were contacted by telephone at 3 and 6 weeks postpartum to obtain information regarding their feeding method and duration. Findings revealed that in-hospital maternal breastfeeding attitudes are predictive of breastfeeding duration. Insufficient milk supply was the reason most often given for discontinuing breastfeeding. Women's husband/partner was found to be the main source of breastfeeding support. We recommend health-care professionals add the IIFAS to their assessment to identify mothers at high risk for discontinuing breastfeeding and to develop and better evaluate breastfeeding promotion programs.
