Background: Countries vary in the number of qualified nurses employed in older adult services. Moreover, students' views of older people nursing as a career differ internationally. Studying future nurses and their career intentions for the field is warranted to meet the increased nurse workforce expectations in terms of quantity and competence.

Aim: To analyse graduating nurse students' interest in older people nursing and the factors associated with it.

Methods: A cross-sectional multicountry survey design was applied. Data were collected between May 2018 and March 2019 from several educational institutions in Finland, Germany, Iceland, Ireland, Lithuania and Spain. Non-probability convenience sampling was used to recruit graduating nurse students (n = 1796). The data were collected with a structured questionnaire comprising background factors and the Willingness sub-scale (six items) of the Students' Interest in Nursing Older People Scale. Data were analysed using a linear mixed model including relevant background variables.

Results: Overall, students' interest in older people nursing was low (score 20.5, on a 0-100 scale). Among the studied countries, Spanish students scored the highest (38.8) and German students the lowest (3.6). Students' interest in older people nursing was associated with country (p < .001), the length of work experience (p = .006), plans for further study (p = .007), competence (p < .001) and the extent that nursing is valued by society (p < .001). The students who were most interested in older people nursing had higher self-reported competence level (p < .001).

Conclusion: In the studied sample of future nurse professionals, interest in older people nursing is low at a time when the field suffers from workforce shortage. As for quality workforce, it was promising that the students who considered working in the field also evaluated themselves as competent.

Implications for practice: Multidimensional actions are required to promote interest in the field, including continued development of competence in both undergraduate education and workplaces, and investing in various career pathways to envisage potential opportunities.
