Design and psychometric evaluation of the fathers' fear of childbirth scale: a mixed method study

Fear of childbirth is reported in 13% of fathers, and it may have adverse consequences for the fathers' health as well as their families. To reduce the fear of childbirth in the expectant fathers, an appropriate screening tool is needed. Due to the lack of a valid and reliable questionnaire to measure fathers' fear of childbirth, this study was conducted to develop the Fathers' Fear of Childbirth Scale and evaluate its psychometric properties.

This mixed method study was conducted in two phases. In the qualitative phase (or item generation), semi-structured interviews were conducted with 20 expectant fathers, and a literature review was performed to generate the Fathers' Fear of Childbirth Scale items pool. In the quantitative phase (or psychometric evaluation), reliability as well as face, content, and construct validity of this scale were evaluated. To establish construct validity, exploratory and confirmatory factor analyses were performed. Reliability was evaluated through internal consistency and composite reliability measures.

The primary version of Fathers' Fear of Childbirth Scale contained 32 items, which were reduced to 17 items while establishing construct validity. Exploratory factor analysis extracted two factors, namely fear of childbirth process (12 items) and fear of hospital (5 items). These factors explained 50.82% of the total variance. Goodness of fit indices within the confirmatory factor analysis was acceptable. Internal consistency and composite reliability indices of all the factors were greater than 0.70.

The Fathers' Fear of Childbirth Scale has a suitable validity and reliability for assessing fear of childbirth in fathers. It is a simple report instrument that can be easily implemented by health care professionals.
