Theoretical methods and practical strategies

Determinant	Methods from theory	Strategy	Tools/Materials
Risk perception and knowledge	Passive learning/providing information	Providing written and verbal information	Letter sent to E explaining the research
			OP explains that early RTW does not increase complaints
			OP explains about risk of ending in work disability scheme
			Researcher explains PW intervention in phone call and sends invitation with brochure, OP also explains and RC guides PW intervention
			RC contributes to brainstorm for solutions
	Active processing of information	Evaluating understanding	OP instructs inventory of stressors to E as home assignment.
			Inventory of barriers for RTW in PW intervention.
Attitude	Verbal persuasion	Providing arguments	OP provides arguments why sick leave does not have to be experienced passively, change in behavior
			OP and RC emphasise the importance of consensus
Skills	Guided practise	Guided practise	Practise explanation of barriers to S with RC.
Self-efficacy	Positive reinforcement	Providing feedback	RC focuses on work abilities of E
		Evaluation	RC evaluates by phone
Outcome expectations	Check for comprehension	Ask E to summarize	OP and RC ask E to summarize expectations with regard to PW intervention
Safety and equality	Guidance by independent person	Train RC to guide PW intervention	Train RC to guide PW intervention
	Create openness and respect	Respect each others barriers and solutions	RC avoids discussion between E and S about truth of barriers
Support	Prevent inhibition	Avoid fixed appointments about RTW before starting PW intervention	OP does not establish RTW date before starting PW intervention
	Support from work environment	Participation of supervisor in RTW process	Increased participation of supervisor in RTW process through PW intervention

Theoretical methods matched with practical strategies identified for the Participatory Workplace intervention program. E = employee, OP = occupational physician, RC = RTW coordinator, S = supervisor.
