French Cross-cultural Adaptation of the Iowa Infant Feeding Attitude Scale (IIFAS) (FRENCH IIFAS)

French Cross-cultural Adaptation of the Iowa Infant Feeding Attitude Scale (IIFAS) and Assessments of Parental Representations of Infant Feeding During Pregnancy in the Auvergne Perinatal Network.

Our study will consist of two parts:

• Part 1: Cross-cultural adaptation of the Iowa Infant Feeding Attitude Scale (IIFAS) among postpartum mothers and co-parents in France and assessment of its psychometric properties
• Part 2: Assessment of cultural representations of infant feeding practices during pregnancy.

The goal of this repeated cross-sectional study is to cross-culturally adapt and evaluate the psychometric properties of the French version of the IIFAS among postpartum mothers in France.

In the part 1 of the study, the main questions it aims to answer are:

• Evaluation of the psychometric properties of the French version of the Iowa Infant Feeding Attitude Scale (IIFAS) among postpartum mothers in France
• Evaluation of the psychometric properties of the French version of the Iowa Infant Feeding Attitude Scale (IIFAS) among postpartum co-parents in France

Participants will be asked :

• to complete the study questionnaires, including the French version of the IIFAS questionnaire.
• to complete the French version of the IIFAS questionnaire a second time 7 days after their initial completion.
• to answer 1 to 4 questions about the infant's current feeding regimen 8 weeks after giving birth.

In the part 2, the goal of this descriptive cross-sectional study is to assess cultural representations of infant feeding practices during pregnancy among pregnant women in France during the first and the third trimesters.

In the part 2 of the study, the main questions it aims to answer are:

• To describe cultural perceptions of infant feeding practices among mothers in France during the first and third trimesters of pregnancy.
• To describe the cultural perceptions of infant feeding practices among co-parents in France during the first and third trimesters of pregnancy.
• To compare the cultural perceptions of infant feeding practices among mothers according to the trimester of pregnancy.
• To analyze the impact of different factors (age, education level, occupation, number of children, geographic origin, socioeconomic status, having been breastfed oneself, having personal experience with breastfeeding, plans to return to work, etc.) on mothers' cultural perceptions of infant feeding practices during the first and third trimesters of pregnancy.
• To compare co-parents' cultural perceptions of infant feeding methods according to the trimester of pregnancy.
• To analyze the impact of different factors (age, education level, occupation, number of children, geographic origin, socioeconomic status, having been breastfed oneself, having a child who was previously breastfed, etc.) on co-parents' cultural perceptions of infant feeding methods during the first and third trimesters of pregnancy.
• To compare the cultural perceptions of infant feeding practices between mothers and co-parents during the first and third trimesters of pregnancy.

Participants will be asked to complete the study questionnaires, including the French version of the IIFAS questionnaire.
