to analyze the validity evidence of the Brazilian version of the Postpartum Specific Anxiety Scale.
psychometric study carried out with 262 women in the first six months after giving birth. The analysis included: item-total correlation, exploratory factor analysis, confirmatory factor analysis, Cronbach's alpha and test-retest. Parallel analysis was used to adjust dimensionality. Evidence of the validity of relationships with other variables was verified through the correlation between the PSAS, the Edinburgh Postpartum Depression scale and the Trait-State Anxiety Inventory.
the removal of eight items improved the quality of fit of the baseline model without affecting reliability. The results indicated stability and evidence of the validity of relationships with other variables showed positive correlations between the PSAS and the other scales used for this purpose.
the Postpartum Specific Anxiety Scale has satisfactory psychometric parameters for the Brazilian context.
分析巴西版产后特定焦虑量表的效度证据。
对262名产后头六个月的女性进行心理测量学研究。分析包括：项目-总分相关性、探索性因素分析、验证性因素分析、克朗巴哈α系数和重测。采用平行分析来调整维度。通过产后特定焦虑量表（PSAS）、爱丁堡产后抑郁量表和特质-状态焦虑量表之间的相关性，验证与其他变量关系的效度证据。
去除八个项目提高了基线模型的拟合质量，且不影响信度。结果表明具有稳定性，与其他变量关系的效度证据显示PSAS与用于此目的的其他量表之间呈正相关。
产后特定焦虑量表在巴西背景下具有令人满意的心理测量学参数。
