Longitudinal correlates of psychological resilience during particle radiotherapy among patients with head and neck cancer: A cross-lagged panel network analysis

<i>Optimism</i> emerges as the primary predictor of resilience in the early stages of particle radiotherapy, with <i>Interconnectedness</i> and <i>PRE</i> assuming greater significance in later phases. Clinical interventions should prioritize bolstering optimism in the initial treatment stages and fostering mechanisms for meaning-making in subsequent phases. The centrality of <i>PRE</i> highlights dynamic targets for resilience-focused interventions in HNC patients.
