Postpartum Excessive Social Support Scale: A Scale Development and Psychometric Testing Study

Abstract

Introduction: In Turkey and other collectivist cultures, child-rearing is a communal effort provided by multiple family members, especially female relatives such as mothers-in-law, aunts, and sisters. Environments with excessively controlling social factors can adversely affect their maternal roles. This study was conducted to develop a measurement tool for determining postpartum excessive social support. Methods: This is a scale development and psychometric evaluation study. In the study, a draft of the Postpartum Excessive Social Support Scale (PESSS) was created, subsequently submitted to expert opinion, and administered to mothers in the postpartum period of 1 to 6 weeks online between March and December 2023 ( n = 440). A factor analysis (including explanatory factor analysis [EFA] and confirmatory factor analysis) was conducted to determine the construct validity of the scale, while Cronbach’s alpha was examined to establish its reliability. Response bias (Hotelling T2) and additivity (Tukey’s test of additivity) of the scale were also determined in the study. Results: For the content validity of the scale, 10 experts from the field of midwifery were consulted (content validity index [CVI] = 0.80). As a result of the EFA, Kaiser–Meyer–Olkin value was found as 0.916. Through factor analysis using the direct oblimin rotation technique, a four-factor structure was identified for the scale, explaining 64.197% of the total variance (social pressure, effect of environmental factors on paternal role, effect of environmental factors on maternal role, and barriers in mother–infant interaction). The internal reliability coefficient of the scale was highly reliable (Cronbach’s alpha = 0.936). There was no response bias in the scale (Hotelling’s T2 = 433.558, p < .001) and it was additive (Tukey’s Non-additivity = 0.000, p < .001). Discussion: The PESSS is a 20-item scale measuring excessive social support between 1 and 6 weeks postpartum. The PESSS serves as a guiding tool for health care professionals to identify excessive environmental pressure hindering mothers’ maternal role and to provide care accordingly. In this context, health care professionals can readily utilize the PESSS in routine postpartum assessments for mothers.
