Participating SMEs and employees
RECRUITMENT
Nine countries participated in the MENTUPP pilot study, with each country recruiting at least one SME from one specific sector as follows: Construction—Albania, Australia, and Ireland; Health—Hungary, Kosovo, and the Netherlands; ICT—Finland, Germany, and Spain. Enterprises with between 10 and 50 employees were considered as small whereas enterprises occupying 50 to 250 employees were identified as medium-sized (Arensman et al. Research Officers (ROs) in each country recruited one or more SMEs for their specified sector. The selection was guided by practical considerations (e.g., approaching an SME with which they already had links, connecting with SME representatives by establishing a connection with workers’ groups, etc.). The aim was to recruit approximately 60–70 employees in the designated sector in each country. Inclusion criteria for the recruitment of employees were persons employed at all levels, part-time and full-time, permanent and non-permanent, inclusion of sub-contractors and agency workers with a contract beyond the follow-up measurement point. No exclusion criteria were defined for employees. Further details with respect to the implementation procedure used during the pilot can be found in Arensman et al.
