ABSTRACT Group leadership is a complex process of understanding group dynamics and leader actions. Practitioners of all disciplines need training to effectively lead groups. Psychometrically sound measures are needed to assess effectiveness of group-leader training. The Group Leader Self-Assessment (GLSA) tool, developed to address this need, demonstrates sound psychometric properties including sensitivity to change (pre- to posttest summary scores t = 15.79. p < .0001. Cohen’s d = 1.74), strong internal consistency (Cronbach α > .90), and high test retest reliability (ICC (3, 1) =.92; F 26.08; df1 = 16; p < .0001). Study results suggest GLSA use may help trainees identify goals for skill development and realize growth in leadership abilities.

组长自我评估 (GLSA) 工具：可靠性和有效性的初步研究

摘要 团队领导是理解团队动态和领导行为的复杂过程。所有学科的从业者都需要接受培训才能有效地领导小组。需要心理测量上合理的措施来评估小组领导培训的有效性。为满足这一需求而开发的组长自我评估 (GLSA) 工具展示了良好的心理测量特性，包括对变化的敏感性（测试前后汇总分数 t = 15.79。p < .0001。Cohen 的 d = 1.74）、强大的内部一致性（Cronbach α > .90）和高测试重测信度（ICC (3, 1) = .92；F 26.08；df1 = 16；p < .0001）。研究结果表明，使用 GLSA 可以帮助受训者确定技能发展目标并实现领导能力的增长。
