Objective Based on the Self-Determination Theory (SDT), this study aims to explore the experiences of workplace maladjustment among generation Z newly graduated nurses, and to provide a reference for optimizing nursing management and interventions.Methods A descriptive qualitative research approach was adopted. Semi-structured interviews were conducted with 20 generation Z newly graduated nurses. The interview data were analyzed using content analysis method. Results Four main themes and twelve subthemes were extracted:Suppression of autonomy needs (frustrations with repetitive tasks, constraints of standar-dized procedures, and imbalance in personal time);Fluctuations in competence development (weakened professional beliefs, insufficient mentoring support, and setbacks in professional confidence); Lack of belongingness (intergenerational alienation and absence of leadership care); Self-overcoming strategies (seeking external emotional support, self-empowerment, maintaining professional boundaries, and positive self-suggestion). Conclusion The adaptation challenges faced by generation Z newly graduated nurses essentially stem from unmet basic psychological needs-autonomy, competence, and belongingness.It is recommended that nursing managers implement flexible empowerment, developmental mentoring, inclusive team environments, and diversified support to precisely address the psychological needs of generation Z newly graduated nurses and to enhance their professional adaptability.
