A Correction on Validation of the Polish PPQ-II: sociodemographic and clinical correlates of perinatal PTSD by Szablewska, A. W., Wójcicka, L., Prajzner, A., Zdun-Ry\.{z}ewska, A., Burdecka, J., and Klasa-Mazurkiewicz, D. (2025). Front. Psychol 16:1698527. doi: 10.3389/fpsyg.2025.1698527

The citation in the section [Section 2 Materials and methods, 2.2 Data collection, 2.2.2 Postpartum PTSD Questionnaire II (PPQ-II)] was erroneously written as [Goliczewska, A., and Szablewska, A. W. (2024). Analysis of biopsychosocial factors in relation to the procreation plans of Poles of reproductive age. Nurs. Probl. 32, 104–110. doi: 10.5114/ppiel.2024.140497].

The text has been updated to read:

“Its structure initially refers to the DSM-IV criteria (American Psychiatric Association, 1994). Unlike the original version created by DeMier et al. (1996) in the revised version by Callahan et al. (2006) each item was rated on a five-point Likert scale ranging from 0 (“never”) to 4 (“frequently and for more than a month”). Higher total scores indicate greater PTSD symptom severity. Permission to use and validate the PPQ-II in Poland was obtained from the original authors (Callahan et al., 2006). The Polish version of the PPQ II questionnaire has been included in Supplementary Appendix 1.”

The citation in the section [Section 3 Results, 3.1 Relevance] was erroneously written as [Nardozza et al., 2025].

It should be [Field, A.P. (2018). Discovering Statistics Using IBM SPSS Statistics. 5th Edition, Sage: Newbury Park.]

The text has been updated to read:

The text has been updated to read: “The exceptionally high reliability of the Polish version aligns with the similarly high values (αC = 0.90, ωM = 0.88, or αC = 0.90) reported for the Spanish (Hernández-Martínez et al., 2021), Portuguese (Alves et al., 2024), and English-language translations (Quinnell and Hynan, 1999).”

It should be [Brzeziński J. (2023). Metodologia badań psychologicznych: wydanie nowe. Warsaw: Wydawnictwo Naukowe PWN.]

The text has been updated to read: “Despite the limited sample size, norms were developed for the Polish version of the PPQ-II. In light of the issue with the normal distribution of the total score [K-S(273) = 0.11, p < 0.001], the development of normative values was preceded by a non-linear transformation of the scores (Brzeziński, 2023).”

The text has been updated to read:

“To assess the psychometric properties of the Polish PPQ-II, we estimated its basic parameters, including reliability and validity. The Polish adaptation demonstrated excellent psychometric characteristics, with high internal consistency for the total score, as well as strong reliability for its subscales. These values are comparable to the previously validated Spanish (Hernández-Martínez et al., 2021), Portuguese (Alves et al., 2024) and English (Quinnell and Hynan, 1999) versions.”

The text has been updated to read: “Finally, we examined the factorial structure of the questionnaire to verify its construct validity. The high Kaiser-Meyer-Olkin (KMO) test value (0.90) and the statistically significant Bartlett's test of sphericity confirmed the suitability of the dataset for exploratory factor analysis (EFA).
