Abstract: Introduction: Suicidal ideation is an understudied issue during the gestational period, requiring valid and reliable instruments for timely measurement and to provide support in perinatal mental health. However, there are limited scales available to assess suicidal ideation in pregnant women in Colombia. Objective: To explore the dimensionality and internal consistency of the Roberts’ scale for suicidal ideation in pregnant women from Santa Marta, Colombia. Methods: 172 pregnant women between 18 and 44 years of age (M=24.7; SD=5.49) completed the Roberts suicidal ideation scale. An exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were carried out to determine dimensionality and Cronbach's alpha and McDonald's omega coefficients were calculated to establish internal consistency. Results: In the CFA the Roberts’ scale indicated a unidimensional internal structure explaining 50.5% of the variance and with adequate goodness-of-fit indicators (X2=5.85, gl=2, p
