The outbreak of the coronavirus disease-2019 (COVID-19) has resulted in a global health crisis. The COVID-19 pandemic has caused psychological distress, both in infected and uninfected individuals. The present study evaluated the validity and factor structure of the COVID-19-Related Psychological Distress Scale (CORPDS) among the general public of the Persian-speaking population. The original version of the CORPDS was translated and back-translated into Persian, followed by a pilot study. A total sample (n = 623) completed an online survey including the CORPDS, Fear of COVID-19 Scale (FCV-19S), Coronavirus Anxiety Scale (CAS), Kessler Psychological Distress Scale (K10), Life Orientation Test-Revised (LOT-R), and Brief Resilience Scale (BRS). The Persian CORPDS had very good internal consistency and moderate test-retest reliability after 4 weeks. Maximum likelihood confirmatory factor analysis (CFA) was conducted to test construct validity (χ²/df = 2.39, CFI = 0.95, SRMR = 0.046, PCLOSE = 0.67 > 0.05, RMSEA = 0.047, 90% CI [0.038, 0.056]). Measurement invariance was performed across gender, including configural invariance, metric invariance, scalar invariance, and error variance invariance, and yielded further support for the two-factor structure of the CORPDS. The CORPDS correlated with the score on the K10 (r = 0.46, p < 0.01, 95% CI [0.43, 0.48]), CAS (r = 0.43, p < 0.01, 95% CI [0.37, 0.45]), FCV-19S (r = 0.29, p < 0.01, 95% CI [0.27, 0.32]), LOT-R (r = − 0.19, p < 0.01, 95% CI [− 0.15, − 0.24]) and BRS (r = − 0.56, p < 0.01, 95% CI [− 0.50, − 0.61]). Resilience was associated with lower psychological distress (β = − 0.54, SE = 0.05, p < 0.001). The findings provide evidence that CORPDS is a reliable and valid instrument for assessing psychological distress generated by COVID-19 among a healthy Persian-speaking population.

2019 年冠状病毒病 (COVID-19) 的爆发导致了全球健康危机。 COVID-19 大流行给感染者和未感染者带来了心理困扰。本研究评估了波斯语人群中 COVID-19 相关心理困扰量表 (CORPDS) 的有效性和因子结构。 CORPDS 的原始版本被翻译并回译为波斯语，随后进行了试点研究。总样本（ n = 623）完成了在线调查，包括 CORPDS、对 COVID-19 的恐惧量表 (FCV-19S)、冠状病毒焦虑量表 (CAS)、凯斯勒心理困扰量表 (K10)、修订后的生活取向测试 (LOT) -R) 和简要弹性量表 (BRS)。波斯语 CORPDS 在 4 周后具有非常好的内部一致性和中等的重测可靠性。进行最大似然验证性因子分析 (CFA) 来测试构建有效性（χ ² /df = 2.39，CFI = 0.95，SRMR = 0.046，PCLOSE = 0.67 > 0.05，RMSEA = 0.047，90% CI [0.038, 0.056]） 。对不同性别的测量不变性进行了测量，包括配置不变性、度量不变性、标量不变性和误差方差不变性，并为 CORPDS 的双因素结构提供了进一步的支持。 CORPDS 与 K10 得分相关 ( r = 0.46, p < 0.01, 95% CI [0.43, 0.48]), CAS ( r = 0.43, p < 0.01, 95% CI [0.37, 0.45]), FCV-19S（ r = 0.29， p < 0.01，95% CI [0.27，0.32]）、LOT-R（ r = − 0.19， p < 0.01，95% CI [− 0.15，− 0.24]）和 BRS （ r = − 0.56， p < 0.01，95% CI [− 0.50，− 0.61]）。 复原力与较低的心理困扰相关（ β = − 0.54， SE = 0.05， p < 0.001）。研究结果证明，CORPDS 是评估健康波斯语人群中由 COVID-19 造成的心理困扰的可靠且有效的工具。
