Nursing teachers have difficulties fulfilling multiple roles expectations and balancing the various dimensions of their roles that may lead to role strain. In order to lack of culturally and academically proper scale in Iran to measure role strain in nursing teachers, localizing a foreign scale in this field is necessary.
The objective of this study was psychometric evaluation of the Role Strain Scale (RSS) and confirming its structural model in an Iranian population.
The present cross- sectional study was conducted in 2012, comprising 302 nursing teachers from around the country who were selected using stratified- cluster sampling. Psychometric evaluation process of the RSS was carried out by Face, content and constructs validity (confirmatory and exploratory factor analysis). Reliability was examined using test-retest and Cronbach's alpha for internal consistency reliability.
In the primary results, in spite of being approved by face and content validity, in Construct validity, fitness indices of original Role Strain Scale showed no satisfactory findings in Iranian data. Therefore, some items from the structural model of original version were extracted by exploratory factor analysis and a five-factor model with 33 items was obtained. These factors were role conflict, role ambiguity, role overload, role incompetence, and role incongruity. New model as Persian version of RSS was confirmed by calculating fitness indices such as GFI = 0.93, AGFI = 0.94, NFI = 0.91, RMSEA = 0.093. Internal consistency reliability for the total scale and subscales were respectively 0.92, and 0.71-0.84. Results from Pearson correlation test indicate a high degree of test-retest reliability (r = 0. 89). ICC was also 0.91.
This reliable and valid scale is academically appropriate for nursing teachers to measure role strain and helps detect and predict a multiplicity of role problems and consequently make educational managers aware of nursing teachers' difficulties while facing with multiple roles and possible future challenges.
护理教师在履行多种角色期望以及平衡其角色的各个维度方面存在困难，这可能导致角色压力。由于伊朗缺乏在文化和学术上合适的量表来测量护理教师的角色压力，因此有必要对该领域的国外量表进行本土化。
本研究的目的是对角色压力量表（RSS）进行心理测量学评估，并在伊朗人群中确认其结构模型。
本横断面研究于2012年进行，包括来自全国各地的302名护理教师，采用分层整群抽样法选取。通过面部、内容和结构效度（验证性和探索性因素分析）对RSS进行心理测量学评估。使用重测法和Cronbach's alpha检验内部一致性信度来检验信度。
在初步结果中，尽管面部和内容效度得到认可，但在结构效度方面，原始角色压力量表的拟合指数在伊朗数据中未显示出令人满意的结果。因此，通过探索性因素分析从原始版本的结构模型中提取了一些项目，得到了一个包含33个项目的五因素模型。这些因素是角色冲突、角色模糊、角色过载、角色无能和角色不一致。通过计算拟合指数，如GFI = 0.93、AGFI = 0.94、NFI = 0.91、RMSEA = 0.093，确认了作为RSS波斯语版本的新模型。总量表和子量表的内部一致性信度分别为0.92和0.71 - 0.84。Pearson相关检验结果表明重测信度较高（r = 0.89）。ICC也为0.
