Objective. To determine the face, content, construct
validity, and reliability of the functional social support
domain of Perinatal Infant Care Social Support (PICSS)
translated into Spanish and adapted for first-time mothers
of term babies.

Methods. Validation study of the functional
social support domain of PICSS, which has 22 items
with response options from 1 to 4; higher scores indicate
greater social support. A translation, back-translation, and
cultural adaptation process took place along with an expert
review to evaluate face and content validity. In total, 210
mothers participated to establish construct validity and
the reliability of the domain. The content validity index and
factor analysis were used to identify the structure of the
domain. Reliability was estimated using Cronbach’s alpha

Results. Linguistic and cultural adaptations
were performed, along with validation and reliability. Face validity for mothers was the following: high comprehension (94%); and for
experts: high comprehension (95.83%), high clarity (96.53%), and high precision
(92.82%). In relevance and pertinence, the content validity index was high (0.97).
Construct validation identified two factors that explained 76% of the variance of the
domain evaluated: factor 1 “Supporting presence -emotional and appraisal support”
(13 items, 39%) and factor 2 “Practical support -informational and instrumental
support-” (9 items, 37%). Cronbach’s alpha value was 0.97.

Conclusion. Given the robust psychometric properties of the Spanish version of the functional social
support domain of PICSS, this may be used to identify the functional social support
in the mothers.
