Validity and reliability of an Arabic-language version of the postpartum specific anxiety scale research short-form in Jordan

Objective: The English-language Postpartum Specific Anxiety Scale (PSAS) is a valid, reliable measure for postpartum anxiety (PPA), but its 51-item length is a limitation. Consequently, the PSAS Working Group developed the PSAS Research Short-Form (PSAS-RSF), a statistically robust 16-item tool that effectively assesses PPA. This study aimed to assess and validate the reliability of an Arabic-language version of the PSAS-RSF in Jordan (PSAS-JO-RSF). Methods: Using a cross-sectional methodological design, a sample of Arabic-speaking mothers (N = 391) with infants aged up to 6 months were recruited via convenience sampling from a prominent tertiary hospital in northern Jordan. Factor analysis, composite reliability (CR), average variance extracted (AVE), McDonald's ω, and inter-item correlation measures were all examined. Results: Explanatory factor analysis revealed a four-factor model consistent with the English-language version of the PSAS-RSF, explaining a cumulative variance of 61.5%. Confirmatory factor analysis confirmed the good fit of the PSAS-JO-RSF (χ²/df = 1.48, CFI = 0.974, TLI = 0.968, RMSEA = 0.039, SRMR = 0.019, p < 0.001). The four factors demonstrated acceptable to good reliability, with McDonald's ω ranging from 0.778 to 0.805, with 0.702 for the overall scale. The CR and AVE results supported the validity and reliability of the PSAS-JO-RSF. Conclusion: This study establishes an Arabic-language version of the PSAS-JO-RSF as a valid and reliable scale for screening postpartum anxieties in Jordan.
