“…The total score ranges from 0 to 56, with a score ≥ 19 indicating that PP-PTSD symptoms exist. The reliability and validity of the Chinese version of the PPQ were tested by Zhang [ 43 ] with a Cronbach’s α of 0.84; the test-retest reliability was 0.88. The Cronbach’s α in this study was 0.83.…”

Background Despite the increased global interest from researchers in postpartum depression (PPD) and postpartum post-traumatic stress disorder (PP-PTSD), studies of PPD in China have shown a wide range of variability. Indeed, the prevalence and risk factors for PP-PTSD have received little attention in China. Aim To determine the prevalence of PPD and PP-PTSD in China, and to examine the relationships between a range of sociodemographic, pregnancy-related, and newborn-related variables, and PPD and PP-PTSD. Methods A cross-sectional study involving 1136 women who returned to the obstetrics clinic for routine postpartum examination were enrolled. The sociodemographic, pregnancy-related, and newborn-related characteristics were collected. Social support, and PPD and PP-PTSD symptoms were measured by the Perceived Social Support Scale (PSSS), the Edinburgh Postnatal Depression Scale (EPDS), and the Perinatal Post-traumatic Stress Questionnaire (PPQ). Results The prevalence rates of PPD and PP-PTSD symptoms were 23.5 and 6.1%, respectively. A multivariate model showed that the presence of PP-PTSD was the strongest risk factor for PPD symptoms and vice versa. Other risk factors for PPD included low sleep quality, low social support and newborn’s incubator admission. In terms of PP-PTSD symptoms, risk factors included the presence of PPD symptoms, non-Han ethnicity, and low social support, while having one child was a protective factor. Conclusions This study addressed some gaps in the literature and provided a better understanding of PPD and PP-PTSD in China, which may contribute to early detection and intervention. Attention should be paid to women who are most susceptible to PPD and/or PP-PTSD, including those with low social support, low sleep quality, newborn’s incubator admission, non-Han ethnicity, and women with siblings.

“…Finally, internal consistency was evaluated and we found values very close to those found in the English version (Cronbach's α = 0.90) 7 and for the Korean version (Cronbach's α = 0.91) 8 . The lowest internal consistency values were found in the Chinese version (Cronbach's α = 0.837) 9 , and especially in the French version (Cronbach's α = 0.77) 10 . This large difference could be explained because all the versions except the French used Likert-type scale while the French version used dichotomous responses.…”

“…Three components accounted for 63.3% of variance. The English, Korean, and Chinese versions explained 65%, 67%, and 51%, respectively, of variance [7][8][9] . Regarding components distribution, none of them match among the published versions, as can be seen in Table 2.…”

To determine the psychometric properties of the Perinatal Post-Traumatic Stress Disorder (PTSD) Questionnaire (PPQ) in Spanish. A cross-sectional study of 432 Spanish puerperal women was conducted, following ethical approval. The PPQ was administered online through midwives' associations across Spain. The Edinburgh Postnatal Depression Scale was used to diagnose postnatal depression for examining criterion validity. Data were collected on sociodemographic, obstetric, and neonatal variables. An exploratory factorial analysis (EFA) was performed with convergence and criterion validation. Internal consistency was evaluated using Cronbach's α. The EFA identified three components that explained 63.3% of variance. The PPQ's convergence validation associated the risk of PTSD with variables including birth plan, type of birth, hospital length of stay, hospital readmission, admission of the newborn to care unit, skin-to-skin contact, maternal feeding at discharge, maternal perception of partner support, and respect shown by healthcare professionals during childbirth and puerperium. The area under the ROC curve for the risk of postnatal depression (criterion validity) was 0.86 (95% CI 0.82–0.91). Internal consistency with Cronbach's α value was 0.896. The PPQ used when screening for PTSD in postpartum Spanish women showed adequate psychometric properties.

“…The PPQ includes 14 questions scored 0–4, and scores of 19 or higher indicate clinically significant symptoms of PTSD. The PPQ has demonstrated good internal consistency and test-retest reliability [ 20 ] and convergent and discriminant validity [ 21 ].…”

Background Involvement in caregiving and tailored support services may reduce the risk of mental health symptoms for mothers after their preterm infant’s neonatal intensive care unit (NICU) discharge. We aimed to compare Family-Centered Care (FCC) with mobile-enhanced Family-Integrated Care (mFICare) on post-discharge maternal mental health symptoms. Method This quasi-experimental study enrolled preterm infant (≤ 33 weeks)/parent dyads from three NICUs into sequential cohorts: FCC or mFICare. We analyzed post-discharge symptoms of perinatal post-traumatic stress disorder (PTSD) and depression using intention-to-treat and per protocol approaches. Results 178 mothers (89 FCC; 89 mFICare) completed measures. We found no main effect of group assignment. We found an interaction between group and stress, indicating fewer PTSD and depression symptoms among mothers who had higher NICU-related stress and received mFICare, compared with mothers who had high stress and received FCC (PTSD: interaction β=-1.18, 95% CI: -2.10, -0.26; depression: interaction β=-0.76, 95% CI: -1.53, 0.006). Per protocol analyses of mFICare components suggested fewer PTSD and depression symptoms among mothers who had higher NICU stress scores and participated in clinical team rounds and/or group classes, compared with mothers who had high stress and did not participate in rounds or classes. Conclusion Overall, post-discharge maternal mental health symptoms did not differ between the mFICare and FCC groups. However, for mothers with high levels of stress during the NICU stay, mFICare was associated with fewer post-discharge PTSD and depression symptoms.
