The Clinical Learning Environment, Supervision and Nurse Teacher (CLES + T) scale evaluates the student nurses' perception of the learning environment and supervision within the clinical placement. It has never been tested in a replication study. The aim of the present study was to evaluate the test-retest reliability of the CLES + T scale. The CLES + T scale was administered twice to a group of 42 student nurses, with a one-week interval. Test-retest reliability was determined by calculations of Intraclass Correlation Coefficients (ICCs) and weighted Kappa coefficients. Standard Error of Measurements (SEM) and Smallest Detectable Difference (SDD) determined the precision of individual scores. Bland-Altman plots were created for analyses of systematic differences between the test occasions. The results of the study showed that the stability over time was good to excellent (ICC 0.88-0.96) in the sub-dimensions "Supervisory relationship", "Pedagogical atmosphere on the ward" and "Role of the nurse teacher". Measurements of "Premises of nursing on the ward" and "Leadership style of the manager" had lower but still acceptable stability (ICC 0.70-0.75). No systematic differences occurred between the test occasions. This study supports the usefulness of the CLES + T scale as a reliable measure of the student nurses' perception of the learning environment within the clinical placement at a hospital.
临床学习环境、督导与护士教师（CLES + T）量表用于评估实习护士对临床实习期间学习环境和督导的感知。该量表从未在重复研究中进行过测试。本研究的目的是评估CLES + T量表的重测信度。对42名实习护士进行了两次CLES + T量表测试，间隔一周。通过计算组内相关系数（ICC）和加权卡帕系数来确定重测信度。测量标准误（SEM）和最小可检测差异（SDD）确定了个体分数的精确度。绘制布兰德-奥特曼图以分析两次测试之间的系统差异。研究结果表明，在“督导关系”“病房教学氛围”和“护士教师角色”子维度中，随时间的稳定性良好至优秀（ICC 0.88 - 0.96）。“病房护理设施”和“护士长领导风格”的测量稳定性较低，但仍可接受（ICC 0.70 - 0.75）。两次测试之间未出现系统差异。本研究支持CLES + T量表作为一种可靠的工具，用于衡量实习护士对医院临床实习期间学习环境的感知。
