Depression is a significant mental health disorder that has a considerable effect globally. Early identification using valid and reliable screening tools, such as the Edinburgh Postnatal Depression Scale (EPDS), is essen-tial for its prevention and management. This review aims to assess the psychometric characteris-tics of the EPDS, concentrating on its reliability and validity in identifying depressive This research is a systematic review of scientific publications sourced from three major databases: ScienceDi-rect. PubMed, and ProQuest. The literature search included works published between 2021 and 2025, utiliz-ing a mix of the keywords AuDepressionAy. AuEdinburgh Postnatal Depression ScaleAy. AuMental HealthAy. AuPsychometricsAy. AuPostpartumAy, and AuPregnancyAy combined with Boolean operators AND and OR to obtain studies related to the EPDS's validity and reliability. Article selection followed the PRISMA framework, us-ing predefined inclusion and exclusion criteria. Out of a total of 337 articles found, 20 were chosen for fur-ther examination. The results suggest that the EPDS exhibits good internal consistency and suffi-cient validity in identifying depressive symptoms. The EPDS is a dependable screening tool for identifying perinatal depression, with its reliability upheld through linguistic and cultural adaptations. Keywords: Depression, edinburgh postnatal depression scale, mental health, psychometrics, postpartum INTRODUCTION Depression can affect women during pregnancy as well as in the postpartum period, impacting both their quality of life and fetal development. Pregnancy is a complex transitional phase that involves physical, emotional, and social changes. While it is often linked with joy and excitement, many pregnant women also face psychological distress, such as depression and anxiety, which can lead to mental health disorders (Rogers et al. , 2. These two conditions frequently occur during the perinatal period and can lead to serious outcomes if not properly managed (Dadi et al. , 2020. Rogers et al. , 2. Worldwide, around 20% of pregnant and recently post-partum women in low and middle-income nations suffer from generalized anxiety disorder, while 8. 3% face post-traumatic stress disorder (Roddy Mitchell et al. , 2. Data from the World Health Organization (WHO) in 2019 indicate that more than 280 million people worldwide experience depression, and approximately 301 million *Corresponding author: henipsik. fk@ub.

Dennis et al. , . conducted A comprehensive review encompassing 102 studies with a total of 221,974 women from 34 different countries, found that 18. 2% of women reported experiencing symptoms of anxiety in the first trimester. A greater prevalence of postpartum depression (PD) was noted during the late postpartum phase . Ae12 month. , with around 3. 18% of parentsAiboth mothers and fathersAifacing PD during this period (Smythe et al. , 2. If proper intervention is not implemented, both conditions could result in a diminished quality of life, reduced productivity, and a higher risk of morbidity and mortality from other health issues (Dagher et al. , 2021. Srinivasan et al. , 2. Multiple interconnected factors, such as hormonal and physiological changes during pregnancy, can lead to depression and anxiety in pregnant women, disrupting their emotional and mood regulation (Dagher et al. , 2. Psychosocial elementsAilike relationship conflicts, lack of social support, domestic violence, and financial stressAifurther increase maternal vulnerability to mental health issues. A meta-analysis by Tilahune et al. , . found that low social support is significantly linked to a higher risk of antenatal depression. A history of psychological disorders, including depression or anxiety before pregnancy, also poses a significant risk. Mitchel et al. , . demonstrated that depression during pregnancy is associated with a greater risk of obstetric complications and adverse birth outcomes, such as preterm birth and low birth weight, as well as impairing motherinfant bonding, delaying cognitive and emotional development, and reducing maternal adherence to prenatal care and health behaviors (Rogers et al. , 2020. Rossi & Parada, 2. Faisal-Cury et al. , . confirmed these findings, showing that antenatal depression increases the risk of obstetric complications and adverse outcomes. Additionally, untreated anxiety during pregnancy can escalate into more severe mental health conditions like panic disorder or postpartum phobia (Dennis et al. , 2017. Faisal-Cury et al. , 2. Given the complex causes and effects of perinatal depression, it is crucial to enhance detection and intervention efforts, such as using screening questionnaires that can efficiently identify depression early in couples planning pregnancy, during pregnancy, and postpartum. These screenings can be integrated into maternal and child health (MCH) clinics, hospitals, primary care centers, and community health services (El-Den et al. , 2022. Faisal-Cury et al. , 2. The Edinburgh Postnatal Depression Scale (EPDS) is among the most common tools used for identifying PPD. It includes 10 items based on depression diagnostic criteria, covering symptoms of depression and anxiety. The EPDS is valid and reliable for both postpartum women and pregnant women in diverse populations (Al-abri et al. , 2025. Dosani et al. Gebregziabher et al. , 2. Joshi et al. confirmed that the Hindi version of the EPDS is a valid and reliable method for detecting depression among pregnant women in India. Similarly. Vyzquez and Myguez . found that the EPDS is effective for screening depression in pregnant women in Spain, with an AUC between 0. 76 and 0. 89, indicating strong discrimination compared to diagnoses from the Structured Clinical Interview for DSM-IV (SCID). While the EPDS is frequently used in research within Indonesia, its use in healthcare settings is still somewhat limited relative to tools like the Self-Reporting Questionnaire (SRQ), especially in community screening and primary care. This systematic review aims to gather and analyze evidence from various countries on the EPDSAos effectiveness, validity, reliability, and psychometric features in detecting depression during pregnancy and This review aims to examine differences in cutoff values, sensitivity, specificity, and 378 | Psychometric Properties of the Edinburgh Postnatal e-ISSN: 2541-450X p-ISSN: 0854-2880 Indigenous: Jurnal Ilmiah Psikologi 2025, 10. , 377-391 the factor structure of the EPDS across various cultural settings. This helps to understand the toolAos effectiveness worldwide better. Additionally, the reviewAos findings are intended to inform the creation of a more precise, culturally tailored postpartum depression screening protocol in Indonesia. It also seeks to promote the use of suitable, standardized, and sustainable measurement tools in maternal and postpartum healthcare services. METHOD Selection Criteria Articles that report on the psychometric properties of the Edinburgh Postnatal Depression Scale (EPDS), such as its validity, reliability, sensitivity, and specificity for depression assessment, are available in full text. The exclusion criteria comprised articles published before 2021 to guarantee current evidence, and non-English articles were also excluded. Participants The PRISMA guidelines ensured a structured, transparent, and standardized approach for identifying relevant articles. Literature searches were carried out on three main databases: ScienceDirect. ProQuest, and PubMed . ee Figure . Quality Appraisal and Data Management The risk of bias for each study was evaluated using the QUADAS-2 tool, which is designed to assess the methodological quality of diagnostic accuracy studies (Reitsma et al. , 2. Any disagreements between reviewers were resolved through discussion until they reached consensus. The assessment focused on four main domains: . patient selection, . index test, . reference standard, and . flow and timing. Each domain was classified as low, unclear, or high risk. The AuunclearAy category was used when the data were insufficient to make a definitive judgment. contrast, the Aunot applicable (N/A)Ay category was used if a particular QUADAS-2 domain was not relevant to the study's design. Search Strategy The literature search was performed in October 2025 using these keyword combinations: AuDepressionAy. AuEdinburgh Postnatal Depression ScaleAy. AuMental HealthAy. AuPsychometricsAy. AuPostpartumAy, and AuPregnancyAy utilizing Boolean operators AND and OR. The same search strategy was applied across all databases to ensure that the relevant results matched the review objectives. Selection Process Initially, 1,631 articles were identified: 620 from ScienceDirect, 76 from PubMed, and 935 from ProQuest. After removing 125 duplicates, 1,506 articles remained. Title and abstract screening narrowed this down to 1,195 articles. Of these, 516 full-text articles were accessible, but 502 were excluded for not meeting the review objectives. Consequently, 14 articles fulfilled the eligibility criteria and were included in the review . ee Table . Data Extraction Data were systematically collected from all qualifying studies using a standardized extraction The information gathered included authors and publication year, country. EPDS version, sample details, cutoff scores, and psychometric indicators such as sensitivity, specificity, area under the curve (AUC), positive predictive value (PPV), negative predictive value (NPV), and reliability Since not all studies reported every diagnostic accuracy metric, only the available data were summarized. Three reviewers independently extracted the data, and any disagreements were resolved through discussion until consensus was reached, followed by a final check to ensure consistency between the narrative data and the results tables.

RESULTS Results This review of 14 articles from 14 different countries showed that the EPDS is effective for assessing depression, although its validity and reliability varied. Differences in psychometric properties across countries were affected by factors such as cultural context, language adaptations, and methodological differences Assessment of the risk of bias The quality assessment of the 14 EPDS validation studies using the QUADAS-2 tool indicated mostly good methodological quality . ee Table . Most studies had a low risk of bias in all areas, though some differences were noted. All studies showed a low risk of bias in the index test domain. However, the Patient Selection and Reference Standard areas included some studies with unclear or high bias risk, especially those from Indonesia. Japan, and Italy. The Flow and Timing domain was generally well-conducted, with only a few studies showing mod-erate to high bias risk. Overall, the majority of studies were methodologically sound, but differences in how reference standards were applied across countries should be taken into account when interpreting the results. 380 | Psychometric Properties of the Edinburgh Postnatal e-ISSN: 2541-450X p-ISSN: 0854-2880 Indigenous: Jurnal Ilmiah Psikologi 2025, 10. , 377-391 Table 1.

Among the fourteen studies reviewed, the psychometric indicators reported included a mix of diagnostic accuracy measures and internal reliability indices, which varied depending on research design and validation goals. The most common parameters were sensitivity, specificity, and area under the curve (AUC), while positive predictive value (PPV) and negative predictive value (NPV) were less frequently reported. This variation, as shown in Table 1 and Figure 2, reflects differences in methodological approaches, cultural contexts, and targeted perinatal phases. In studies assessing diagnostic accuracy. EPDS sensitivity typically ranged from 75% to over 90%, indicating a solid ability to detect perinatal depression (Atuhaire et al. , 2023. de Fraga et , 2021. Gebregziabher et al. , 2025.

Low, high, and unclear indicate low risk of bias, high risk of bias, and insufficient information to permit judgment. In accordance with QUADAS-2 guidance, no numerical scores were assigned. Studies reporting NPV showed consistently high values (> 90%), highlighting the EPDSAos strong ability to rule out perinatal depression, whereas PPV ranged from moderate to high, depending on depression prevalence in the study populations (Atuhaire et al. , 2023. Buhagiar et al. AUC values, especially those comparing EPDS to clinical diagnostic standards like DSM-5. SCID-5, or MINI in countries including Cameroon. Brazil. Eritrea. Uganda. Kenya. Singapore, and the U. , generally ranged from 75 to 0. 94, indicating good to excellent discriminatory power (Gebregziabher et al. , 2025. Mutiso et al. , 2023. Zeng et al. , 2. While seven studies demonstrated strong criterion validity of the EPDS against gold standards and revealed optimal cutoff scores between 9 and 13, the variation in scores underscores the influence of cultural, linguistic, and perinatal phase differences on the instrument's performance. In addition to diagnostic accuracy measures, multiple studies examining construct validity and internal reliability found CronbachAos values mostly Ou0. 80, for both local-language versions and the shortened EPDS-9, demonstrating strong internal consistency (Chen et al. , 2023. Cheng et al. , 2025. Sari et al. , 2021. Stefana et al. , 2. Overall, the emerging pattern indicates a tradeoff between sensitivity and specificity: lowering the cutoff score boosts sensitivity but decreases specificity, whereas higher cutoff scores improve specificity but raise the risk of false negatives. EPDS performance also varied across different perinatal phases. Research involving pregnant women in China. Singapore, and Indonesia generally used lower cutoff scores .

In contrast, research involving postpartum women across Brazil. Eritrea. Italy. Oman, and the United States found higher optimal cutoff Petriano et al. | 383 e-ISSN: 2541-450X p-ISSN: 0854-2880 Indigenous: Jurnal Ilmiah Psikologi 2025, 10. , 377-391 scores .

These findings highlight the need to interpret EPDS scores within the specific perinatal context to ensure a proper balance between sensitivity and specificity. Figure 2 Overview of the Psychometric Evaluation Framework for the EPDS DISCUSSION This systematic review confirms that the Edinburgh Postnatal Depression Scale (EPDS) reliably detects perinatal depression across various cultural and clinical settings. It shows sensitivity between 80% and 92%, specificity from 75% to 90%, and high AUC values . 83Ae0. While the EPDS is an effective screening tool, variability in sensitivity, specificity, and optimal cutoff scores . Ae. suggests its performance depends heavily on the specific context of use (Levis et al. The observed variation in sensitivity, ranging from 80% to 92%, can be attributed to 384 | Psychometric Properties of the Edinburgh Postnatal e-ISSN: 2541-450X p-ISSN: 0854-2880 Indigenous: Jurnal Ilmiah Psikologi 2025, 10. , 377-391 differences in screening objectives and population characteristics. Studies in high-risk populations or primary care settings tend to report higher sensitivity, as their primary aim is to minimize undetected cases of depression . alse negative. (Kendall-Tackett, 2. In contrast, studies in general populations or referral clinical settings often emphasize higher specificity to avoid In this context, higher sensitivity reflects a preventive screening approach, whereas higher specificity reflects the need for more stringent clinical confirmation (Levis et al. , 2020. Qiu et al. , 2. Differences in optimal EPDS cutoff scores . Ae. not only reflect variations in research methods but also stem from differences in clinical depression definitions, cultural backgrounds, and the specific perinatal phase evaluated (Levis et al. , 2020. Qiu et al. , 2. Studies employing structured diagnostic interviews like DSM-5. SCID-5, or MINI suggest that lower cutoff scores . Ae. are more effective for detecting mild to moderate depression, especially during pregnancy (Levis et al. , 2020. Qiu et al. , 2. This is likely due to the overlap between emotional symptoms, anxiety, and mood shifts in pregnancy, which may not satisfy criteria for major depressive disorder but are still clinically relevant (Kendall-Tackett, 2024. Stefana et al. , 2. In contrast, during the postpartum period, higher EPDS cutoff scores . Ae. tend to improve accuracy in diagnosing major depression, as higher thresholds boost specificity for clinical diagnosis postpartum. Individual participant data meta-analyses support this, showing optimal EPDS performance at cutoff scores Ou11 for detecting perinatal major depression (Qiu et al. , 2. Cross-cultural validation studies also confirm that a cutoff Ou11 offers a better balance between sensitivity and specificity among postpartum women than during pregnancy, especially when compared to structured clinical diagnostic standards (Djatche Miafo et al. , 2. The mechanism underlying this pattern relates to the stabilization of symptoms after childbirth, whereby depressive manifestations become more persistent and specific and are no longer confounded by transient emotional responses associated with acute hormonal changes. Consequently, a higher screening threshold becomes more clinically appropriate in the postpartum period (Kendall-Tackett, 2. Therefore, the application of a single uniform EPDS cutoff score across all perinatal phases may reduce screening accuracy and introduce clinical bias, either through under-detection during pregnancy or over-detection in the postpartum period. This concern is also emphasized in longitudinal studies demonstrating differing threshold requirements between antenatal and postpartum periods (Tanuma-Takahashi et al. , 2. Practically, these results have significant implications for healthcare providers. For nurses and midwives involved in maternal and neonatal care, a more sensitive cutoff in the EPDS can serve as an early warning system to spot mothers who may need additional psychological support (Stefana et al. , 2024. Sultan et al. , 2. For physicians and clinical psychologists, recognizing the variability in cutoff scores aids in interpreting EPDS results within context. This helps ensure that scores are not seen as final diagnoses but rather as a starting point for further clinical evaluation. (Namatovu et al. , 2025. Sultan et al. , 2. This approach is essential to prevent two major risks: under-detection of perinatal depression, which may adversely affect maternal health and child development, and over-detection, which may impose unnecessary psychological burden and stigma. The implications for pregnant and postpartum women are equally significant. Sensitive and contextualized screening for perinatal depression using the EPDS enables early identification of depressive symptoms before progression to more severe disorders, thereby allowing timely and targeted psychosocial interventions. Longitudinal evidence indicates that postpartum depressive symptoms identified through the EPDS are associated with the quality of motherAechild interactions and childrenAos emotional and neurobehavioral development during the first year of life, suggesting Petriano et al. | 385 e-ISSN: 2541-450X p-ISSN: 0854-2880 Indigenous: Jurnal Ilmiah Psikologi 2025, 10. , 377-391 that early detection and intervention may improve maternal quality of life and child developmental outcomes (Kumar et al. , 2. Furthermore, research shows that postpartum depression risk identified via EPDS is associated with impaired motherAeinfant bonding. That screening, followed by psychosocial follow-up, can mitigate long-term negative effects on maternal relationships (Ernawati & Rahayuningsih, 2. These findings are reinforced by predictive reviews demonstrating that the use of sensitive screening instruments such as the EPDS facilitates earlier care delivery and contributes to the prevention of long-term psychological complications in both mothers and children (Motofelea et al. , 2. Although the EPDS has demonstrated strong cross-cultural validity across international contexts, it is important to emphasize that the lack of local EPDS validation in Indonesia represents not merely an academic research gap but a tangible clinical risk within maternal and child healthcare practice (Dinescu et al. , 2026. Putri et al. , 2025. Zeng et al. , 2. The direct adoption of EPDS cutoff scores from international studies without adjustment to Indonesian cultural, linguistic, and healthcare system characteristics may lead to misclassification of peri-natal depression (Qiu et al. , 2. Clinically, this may result in two equally detrimental out-comes: failure to identify mothers with depressive symptoms requiring intervention . nder-detectio. or excessive labeling of mothers exhibiting adaptive emotional responses during pregnancy and the postpartum period . ver-detectio. (Moyer et al. , 2. Both scenarios have direct implications for clinical decision-making quality, referral accuracy, and effectiveness, and the psychological burden experienced by mothers and their In healthcare systems with limited resources, such misclassification may also contribute to suboptimal service allocation (Perrykkad et al. , 2. Therefore, culturally sensitive and population-based EPDS validation in Indonesia constitutes an urgent clinical necessity rather than merely a methodological priority, to ensure that perinatal depression screening truly functions as a maternal health protection tool rather than a source of diagnostic bias within healthcare services (Putri et al. , 2025. Vanderkruik et al. , 2. Nevertheless, this discussion must be interpreted in light of several methodological limitations within the available literature. Most reviewed studies employed cross-sectional designs and applied heterogeneous reference diagnostic standards, thereby limiting understanding of the temporal stability of EPDS scores and their ability to predict long-term maternal mental health These limitations underscore the need for longitudinal research to evaluate score consistency over time and the predictive validity of the EPDS for diverse maternal mental health Moreover, local validation studies that explicitly account for linguistic, cultural, and perinatal phase differences are essential to ensure more accurate, safe, and clinically relevant EPDS use across healthcare contexts in Indonesia (Putri et al. , 2025. Sari et al. , 2. Overall, these findings affirm that the strength of the EPDS is determined not only by its psychometric quality but also by how the instrument is interpreted and integrated within healthcare With a more comprehensive understanding of sensitivity variation, cutoff scores, and cultural influences, the EPDS has the potential to function as a screening tool that is not only statistically robust but also clinically meaningful, contributing substantively to the improvement of maternal healthcare quality in Indonesia. Looking forward, the integration of stronger longitudinal evidence and local validation is expected to further reinforce the role of the EPDS as a safe, effective, and sustainable screening instrument in routine clinical practice (Sultan et al. , 2. 386 | Psychometric Properties of the Edinburgh Postnatal e-ISSN: 2541-450X p-ISSN: 0854-2880 Indigenous: Jurnal Ilmiah Psikologi 2025, 10. , 377-391 CONCLUSION The Edinburgh Postnatal Depression Scale (EPDS) is an effective and consistent screening tool for detecting depression among pregnant and postpartum women across diverse cultural and healthcare settings. However, variations in cutoff scores and differences in EPDS performance across perinatal phases indicates that the use of a single universal threshold is not appropriate for all conditions. As a result, the results of EPDS screenings should be understood within context and utilized as a preliminary step in the care of maternal mental health, followed by additional evaluation and suitable interventions. In practical terms, the absence of local validation, especially in developing nations like Indonesia, poses not just a limitation in research but also a potential clinical risk due to the misclassification of perinatal depression. Therefore, initiatives aimed at cultural adaptation, local validation, and enhancing follow-up healthcare systems are crucial to ensure that EPDS screening effectively contributes to safeguarding maternal mental health and enhancing the quality of maternal and child healthcare.
