Psychometric evaluation and validation of the Postpartum Specific Anxiety Scale for the Spanish-speaking population: PSAS-ES.

OBJECTIVE: The transition to motherhood is a period of risk for the development of mood disorders. Postpartum anxiety has not been as thoroughly studied as other emotional disorders despite its impact on mothers and their babies. The absence of standardized programmes for early detection and specific tools for its diagnosis means postpartum anxiety is often underestimated or overshadowed. This study aimed to translate and validate the Postpartum Specific Anxiety Scale [PSAS] for the Spanish population and to analyse its reliability as an exploratory tool for specific anxiety in mothers. METHOD: Four stages were followed in this research: translation and back-translation to obtain the Spanish version [PSAS-ES]; preliminary pilot study to explore the comprehensibility and ease of responding the items (n = 53); convergent validity analyses (n = 644); and test-retest reliability (n = 234). RESULTS: The PSAS-ES has shown to have good acceptability, convergent validity and high internal consistency with a Cronbach's α coefficient of 0.93 for the overall scale of PSAS. The four factors had good reliability. The results of test-retest was 0.86, indicating excellent stability over time in the first 16 weeks. CONCLUSION: The psychometric results show that the PSAS-ES is a valid tool to explore and detect anxiety in Spanish mothers between 0 and 16 weeks postpartum.

A validation of the Postpartum Specific Anxiety Scale 12-item research short-form for use during global crises with five translations.

BACKGROUND: Global crises inevitably increase levels of anxiety in postpartum populations. Effective and efficient measurement is therefore essential. This study aimed to create a 12-item research short form of the 51-item Postpartum Specific Anxiety Scale [PSAS] and validate it for use in rapid response research at a time of global crises [PSAS-RSF-C]. We also present the same 12-items, in five other languages (Italian, French, Chinese, Spanish, Dutch) to increase global accessibility of a psychometric tool to assess maternal mental health. METHODS: Twelve items from the PSAS were selected on the basis of a review of their factor loadings. An on-line sample of UK mothers (N = 710) of infants up to 12 weeks old completed the PSAS-RSF-C during COVID-19 'lockdown'. RESULTS: Principal component analyses on a randomly split sample (n = 344) revealed four factors, identical in nature to the original PSAS, which in combination explained 75% of the total variance. Confirmatory factor analyses (n = 366) demonstrated the four-factor model fit the data well. Reliability of the overall scale and of the underlying factors in both samples proved excellent. CONCLUSIONS: Findings suggest the PSAS-RSF-C may prove useful as a clinical screening tool and is the first postpartum-specific psychometric scale to be validated during the COVID-19 pandemic. This offers psychometrically sound assessment of postpartum anxiety. By increasing the accessibility of the PSAS, we aim to enable researchers the opportunity to measure maternal anxiety, rapidly, at times of global crisis.
