Behavioral niceness has an important place in maintaining interpersonal relationships. Scale studies are needed to determine the level of niceness that plays a role in individuals' development of healthy daily interactions with other people. In this study, firstly, the psychometric properties of the Niceness Scale, which consists of six items, were examined in a Turkish sample ( = 404). Confirmatory factor analysis confirmed the six-item one-dimensional structure, and item response analysis revealed a high level of discrimination across all items. The relationship of the Niceness Scale with previously validated and reliable scales was examined, and it was found that criterion-related validity was achieved. Furthermore, a network analysis revealed the relationships between the variables more clearly. In the scale's measurement invariance analysis, consistency was found for both genders. Then, the reliability of the Niceness Scale was proven with different reliability values. In a different Turkish sample ( = 372), it was determined that depression played a statistically significant mediating role in the relationship between niceness and subjective happiness. In conclusion, this study revealed that the one factor and six-item Niceness Scale are valid and reliable in the Turkish sample. Moreover, boosting niceness has been determined to reduce negative situations such as depression and therefore enhance subjective happiness. All these important implications about niceness are discussed in light of the literature.
行为友善在维持人际关系中占有重要地位。需要进行量表研究来确定友善程度在个体与他人建立健康日常互动过程中所起的作用。在本研究中，首先，在一个土耳其样本（N = 404）中检验了由六个项目组成的友善量表的心理测量特性。验证性因素分析证实了六项目单维结构，项目反应分析表明所有项目都具有较高的区分度。研究了友善量表与先前经验证且可靠的量表之间的关系，发现达到了与标准相关的效度。此外，网络分析更清晰地揭示了变量之间的关系。在量表的测量不变性分析中，发现两性具有一致性。然后，用不同的信度值证明了友善量表的信度。在另一个土耳其样本（N = 372）中，确定抑郁在友善与主观幸福感之间的关系中起到了统计学上显著的中介作用。总之，本研究表明，单因素六项目的友善量表在土耳其样本中是有效且可靠的。此外，已确定提升友善程度可减少诸如抑郁等负面情况，从而增强主观幸福感。结合文献对所有这些关于友善的重要启示进行了讨论。
