Breast cancer is a major public health issue capable of harming personal satisfaction. The Satisfaction with Life Scale (SWLS) is one of the most commonly employed tools with which life satisfaction could be measured. The present study aims to assess the Persian version of the Satisfaction with Life Scale (SWLS) among Iranian women with breast cancer. In this descriptive cross-sectional study, a total of 115 women coping with breast cancer in Iran were selected through a convenience sampling method. The participants completed a demographic questionnaire, the Persian version of the SWLS, and the DASS-21. The psychometric properties of the SWLS were examined as construct validity based on the confirmatory factor analysis (CFA), reliability using Cronbach’s alpha, and divergent validity by examining the relationship with the DASS-21. Results of the CFA indicated that a single-factor model provides a good fit to the data: (_sbX² = 4.40 (p = 0.36); SRMR = 0.019; CFI = 0.99; NFI = .99; IFI = 1.0; RFI = .97; AGFI = 0.94; GFI = 0.99; RMSEA = .029). Cronbach’s alpha coefficient for the SWLS was 0.84. Significant negative correlations were found between SWLS and DASS-21 scores for anxiety (r = −0.58), depression (r = −0.61), and stress (r = −0.59) that demonstrated an acceptable divergent validity. As findings, this scale can be used to respect Iranian women with breast cancer as a reliable measurement tool for satisfaction with life. It could thus be recommended more extensively as an indicator of satisfaction with life in other oncological patients.

乳腺癌是能够损害个人满意度的主要公共卫生问题。生活满意度量表（SWLS）是最常用的工具，可以用来衡量生活满意度。本研究旨在评估伊朗乳腺癌女性对生活满意度量表（SWLS）的波斯语版本。在此描述性横断面研究中，通过便利抽样方法，总共选择了115名伊朗应对乳腺癌的妇女。参与者完成了一份人口统计学调查表，SWLS的波斯文版本和DASS-21。根据验证性因子分析（CFA），使用Cronbach'sα的信度和通过检验与DASS-21的关系的散度信度，对SWLS的心理计量学性质进行了检验，以检验其结构效度。_sb X ²  = 4.40（p  = 0.36）；SRMR = 0.019；CFI  = 0.99；NFI = .99；IFI = 1.0；RFI = 0.97；AGFI  = 0.94；GFI  = 0.99；RMSEA = .029）。SWLS的Cronbachα系数为0.84。在焦虑（r = -0.58），抑郁（r = -0.61）和压力（r = -0.59）的SWLS和DASS-21得分之间发现显着负相关，这表明可接受的发散性有效性。结果发现，该量表可以用来尊重伊朗的乳腺癌女性，以此作为衡量生活满意度的可靠工具。因此可以更广泛地推荐它作为其他肿瘤患者对生活满意度的指标。
