The aim of the present study was to use Rasch analysis to assess the psychometric properties of the five-item version of the General Self-Efficacy Scale (GSES) amongst adolescents aged 13 to 19. In this cross-sectional study, 6265 adolescents responded to a web-based questionnaire. Data collected from lower and upper secondary schools in Norway, during 2018, were analysed using the partial credit parameterisation of the unidimensional Rasch model. The five-item version of the GSES was found to be unidimensional and to have acceptable reliability. The targeting of the scale could have been better. All items had ordered thresholds, indicating that the response categories worked quite well. The five-item version of the GSES has potential for measuring self-efficacy in a general population of adolescents. In surveys concerning adolescents' mental health, it is important to include aspects of positive mental health and health-promoting factors, such as self-efficacy.
本研究旨在使用 Rasch 分析评估 13 至 19 岁青少年五分量表一般自我效能感量表 (GSES) 的心理测量特性。在这项横断面研究中，6265 名青少年回答了一个基于网络的问卷。2018 年，在挪威的初中和高中收集的数据使用单维 Rasch 模型的部分信用参数化进行了分析。发现 GSES 的五分量表具有单维性和可接受的可靠性。该量表的目标可能更好。所有项目都有有序的门槛，表明反应类别运作良好。GSES 的五分量表具有在一般青少年人群中测量自我效能感的潜力。在涉及青少年心理健康的调查中，重要的是要包括积极心理健康和促进健康因素的方面，如自我效能感。
