Psychological resources have been shown to play a prominent role in buffering against stress and are associated with various positive constructs, including grit, defined as having the disposition to pursue long-term goals with both passion and perseverance.
The objective of this study was to validate a new scale developed to measure the psychological resources of grit.
A quantitative research study was conducted online with an international sample of 277 adults from a range of professional backgrounds. The psychometric properties of the 20-item Grit Psychological Resources Scale (GPRS) were evaluated by performing tests of reliability and validity.
Reliability tests provided evidence of high internal consistency (α = 0.91) and test-retest reliability (r = 0.75). Demographic variables did not significantly predict scores or influence survey completion. Face, content and convergent validity provided additional psychometric support for the GPRS with this sample. Confirmatory factor analysis results supported a second-order model with four sub-scales. The first-order factors loaded highly onto the second-order factor, with correlations ranging from 0.80 to 0.97.
The GPRS showed satisfactory psychometric properties, indicating that the scale is a reliable and valid instrument for measuring the psychological resources of grit. This scale can be used to identify more targeted developmental approaches for personal and professional growth. Further, the tool enables information to be gathered on changes pre- and post-improvement initiatives to assess their effectiveness in training and continuing education.
心理资源已被证明在缓冲压力方面发挥着重要作用，并与各种积极的构念相关，包括毅力，即被定义为具有以热情和毅力追求长期目标的倾向。
本研究的目的是验证一个新开发的用于测量毅力心理资源的量表。
对来自不同专业背景的277名成年人的国际样本进行了在线定量研究。通过进行信效度测试来评估20项毅力心理资源量表（GPRS）的心理测量特性。
信度测试提供了高内部一致性（α = 0.91）和重测信度（r = 0.75）的证据。人口统计学变量并未显著预测得分或影响调查完成情况。表面效度、内容效度和收敛效度为该样本中的GPRS提供了额外的心理测量支持。验证性因素分析结果支持了一个具有四个子量表的二阶模型。一阶因素与二阶因素高度相关，相关系数范围为0.80至0.97。
GPRS显示出令人满意的心理测量特性，表明该量表是测量毅力心理资源的可靠且有效的工具。该量表可用于确定更具针对性的个人和职业发展方法。此外，该工具能够收集改进举措前后的变化信息，以评估其在培训和继续教育中的有效性。
