The aim of this study was to validate the Polish version of the Somatosensory Amplification Scale (SSAS-PL) and examine its psychometric properties in clinical and non-clinical samples. : The study included 1128 participants (711 healthy adults, 194 cardiac patients, 223 psychiatric patients). The analyses were categorized into exploratory and confirmatory phases. Exploratory analyses were conducted on a randomly selected sample that comprised 60% of the study participants (training sample) to estimate the reliability (Cronbach's alpha) and factorial validity (EFA with varimax rotation). Confirmatory analyses were performed on an independent (test) sample that represented 40% of the total sample size to facilitate the cross-validation of the factor structure (CFA) and to assess the convergent and discriminant validities (using the HTMT method) in relation to health anxiety (SHAI) and psychopathological symptoms (KOFF-58). Additionally, measurement invariance was examined with respect to gender (female vs. male) and health status (healthy vs. clinical). The SSAS-PL demonstrated good internal consistency (α = 0.75-0.78) after removing item 1. A one-factor structure showed the best fit and theoretical interpretability. The measurement invariance was supported across clinical groups. The SSAS-PL showed convergent validity with the measures of somatic symptoms, anxiety, and health anxiety. It demonstrated discriminant validity from other psychopathology measures. The SSAS-PL was a reliable and valid measure of somatosensory amplification in the Polish population. Its unidimensional structure aligned with most cross-cultural adaptations. The scale may be useful for assessing somatosensory amplification in both research and clinical settings in Poland. Further research on its utility in specific clinical populations is warranted.
本研究的目的是验证波兰语版的体感放大量表（SSAS-PL），并在临床和非临床样本中检验其心理测量特性。该研究纳入了1128名参与者（711名健康成年人、194名心脏病患者、223名精神科患者）。分析分为探索性和验证性阶段。对随机抽取的占研究参与者60%的样本（训练样本）进行探索性分析，以估计信度（克朗巴哈系数）和因子效度（采用方差最大化旋转的探索性因子分析）。对占总样本量40%的独立（测试）样本进行验证性分析，以促进因子结构的交叉验证（验证性因子分析），并评估与健康焦虑（SHAI）和精神病理症状（KOFF-58）相关的收敛效度和区分效度（使用HTMT方法）。此外，还检验了性别（女性与男性）和健康状况（健康与临床）方面的测量不变性。去除项目1后，SSAS-PL表现出良好的内部一致性（α = 0.75 - 0.78）。单因素结构显示出最佳拟合度和理论可解释性。各临床组均支持测量不变性。SSAS-PL与躯体症状、焦虑和健康焦虑的测量指标显示出收敛效度。它与其他精神病理学测量指标显示出区分效度。SSAS-PL是波兰人群中体感放大的可靠且有效的测量工具。其单维结构与大多数跨文化适应性研究一致。该量表可能有助于在波兰的研究和临床环境中评估体感放大。有必要进一步研究其在特定临床人群中的效用。
