A cancer disease can be associated with psychological stress for both patients and partners. To date, no psychometrically tested measuring instrument has been available for the assessment of cancer-specific distress in partners of cancer patients. The Questionnaire on Stress in Partners of Cancer Patients (QSC-P) was developed to close this gap. This study validates the QSC-P in two subsamples of n1 = 227 and n2 = 297 partners of cancer patients by application of exploratory factor analysis methods in n1 and confirmatory factor analysis methods in n2. Additionally, correlations with common measures of anxiety, depression, and quality of life were calculated. A cut-off for high distress was determined. A three-factor structure with 23 items that was generated in n1 could be replicated in n2. Reliability and validity analyses resulted in good to very good characteristic values of the resulting QSC-P (α = .84- .93). A cut-off of 68.5 with good sensitivity and specificity was calculated. The QSC-P proved to be a valid and reliable measuring instrument for psychological distress of partners of cancer patients and a helpful tool for clinical care and research. Future directions include development of a short-form and detailed comparison of the sexes.
癌症疾病可能会给患者及其伴侣带来心理压力。迄今为止，尚无经过心理测量学测试的测量工具可用于评估癌症患者伴侣的癌症特异性痛苦。癌症患者伴侣压力问卷（QSC-P）的开发就是为了填补这一空白。本研究通过在n1样本中应用探索性因素分析方法以及在n2样本中应用验证性因素分析方法，对n1 = 227和n2 = 297名癌症患者伴侣的两个子样本进行了QSC-P的验证。此外，还计算了与焦虑、抑郁和生活质量常用测量指标的相关性。确定了高痛苦的临界值。在n1样本中生成的包含23个条目的三因素结构能够在n2样本中得到复制。信效度分析得出了所得QSC-P的良好至非常好的特征值（α = 0.84 - 0.93）。计算出临界值为68.5，具有良好的敏感性和特异性。QSC-P被证明是一种用于评估癌症患者伴侣心理痛苦的有效且可靠的测量工具，也是临床护理和研究的有用工具。未来的方向包括开发简版以及对性别进行详细比较。
