RESUMEN
The aim of the authors in this study was to determine the psychometric properties of the Greek adaptation of the High-Risk Pregnancy Stress Scale (HRPSS) in a sample of high-risk hospitalized pregnant women. The sample consisted of 133 high-risk pregnant women with gestational age from 9 to 37 weeks. Data were collected between February and June of 2014. HRPSS was "forward-backward" translated from English to Greek. Principal axis factoring with promax rotation was used to test the factor structure of the HRPSS. Measures of state anxiety (STAI) and depressive symptoms (EPDS) were used to assess the convergent validity of the HRPSS. Exploratory factor analysis suggested three factors: concerns of pregnancy, movement restriction, and isolation and restriction of external activities. Construct validity was confirmed by computing correlations between the HRPSS and constructions of anxiety and depressive symptoms. Internal consistency reliability was satisfactory (α = 0.813). The original factor structure of the HRPSS was only partly replicated. The results of the exploratory factor analysis suggested that a three-factor solution instead of a two-factor solution would be the most adequate. The HRPSS is an appropriate measure for assessing the levels of concerns regarding pregnancy outcome, movement restriction, isolation, and external activity restrictions in Greek high-risk pregnant women.
