BackgroundNurse managers need to possess specific knowledge, skills, and attitudes to fulfil their roles and responsibilities and exemplify that they are competent to do their jobs. However, there is a paucity of data on the performance-based training needs of middle-level nurse managers in Jordan.AimTo identify the performance-based training needs of middle-level nursing managers working in Jordanian governmental hospitals and to evaluate the differences in perceived performance-based training needs based on their socio-demographic and professional characteristics.MethodsA descriptive cross-sectional design was utilized. The study recruited 132 nurses from three governmental hospitals in Jordan using convenience sampling. An online survey included the Hennessy-Hicks Training Needs Questionnaire was used for data collection. Ethical approvals were obtained to conduct the study. Data were analysed using descriptive and inferential statistics using SPSS version 28.Results'Designing a research study' item had the highest perceived need for training (M = 2.5, SD & PLUSMN; 2.5), while 'establishing a relationship with patients' item had the lowest (M = 0.4, SD & PLUSMN; 1.2). Nurses with more experience (F = 2.9, df = 131, P < 0.05), and nurses who worked in specialized units (F = 2.3, df = 131, P < 0.05) had significantly lower training needs than nurses with lesser years of experience, and nurses who worked in outpatient departments. In addition, age, gender, prior training in nursing management, and years of experience as middle-level nurse managers significantly predicted the levels of training needed (R-2 = 0.23, P < 0.001).ConclusionThe findings reflected the need for training on several managerial competencies. Future research can help identify other personal and organizational factors affecting performance-based training needs.
