“…According to the social identity theory, identity can influence individual thinking, emotion and behaviour (Liu et al, 2021); therefore, professional identity will inevitably have an impact on the nursing practice (Shun, 2021). Nurses with a higher professional identity have a stronger sense of professional benefit, and can experience more pride, efficacy, achievement and happiness at work; therefore, their work enthusiasm and caring ability are higher (Luo et al, 2018; Owens, 2020). On the contrary, nurses with low professional identity will tend to exhibit negative attitudes and behaviours at work and reduce their sense of belonging, and then reduce their work engagement when they perceive that their self‐worth is not reflected in work and that their profession is not recognized by the society (Wang, Hu, et al, 2019).…”
