^aPredictors: Age, Professional training in health, Years of experience at the CLS, Hours per week working at the CLS, Location of work.

^bPredictors: Age, Gender, Professional training in health, Years of experience at the CLS, Hours per week working at the CLS, Location of work, Work-related demands.

^cPredictors: Age, Gender, Professional training in health, Years of experience at the CLS, Hours per week working at the CLS, Location of work, Work-related demands, Organization does not listen carefully to wishes or needs of volunteer/employee, There is little contact with other volunteers because they work from home, The support team is not accessible, although there is a need for it, Volunteer has hardly time for a break, The organization applies the philosophy of non-intervention, The identity caller/chatter is anonymous, therefore the volunteer does not know what effect the conversation has had, The shifts are too long, Volunteer/employee must work night shifts, The location of the telephone helpline is not optimal.
