Resumen
- Although pregnancy increases the vulnerability to anxiety, no specific assessment instruments are usually used to detect it. The objective of this study was to adapt the Pregnancy Related Anxiety Questionnaire (PRAQ) to Spanish population, as well as analyze its validity and reliability. A sample of 367 nulliparous pregnant women with a normal risk status filled in a socio-demographic and obstetric-gynaecological questionnaire, the PRAQ, the Edinburgh Postnatal Depression Scale (EPDS) and the State-Trait Anxiety Inventory (STAI). After performing a factorial analysis, a five-factor model that explains 53.1% of the variance was obtained. Estimates of internal consistency reliability were adequate (range = .78 to .93) for the five factors included in the final confirmatory factor analysis, and for the total scale (.97). Significant correlation among PRAQ, EPDS, and STAI was found (p < .001). The 85th percentile (score 234 or more) was used as a cut-off point to identify those women with high pregnancy-specific anxiety. In accordance with the results obtained, the PRAQ can be considered a useful screening tool to evaluate pregnancy-related anxiety among the Spanish population.
