Results of regression analyses for need for recovery on the individual and the department level

		Department level
			Employees per department
Independent variable	Individual level	All departments	n>5	n>10	n>15	n>20	n>25
Means, standard deviations, and multiple regression analyses with 10 psychosocial job characteristics as independent variables and need for recovery as dependent variable.
For each analysis are reported: the number of individual respondents, the number of departments, the average number of individuals per department, the mean and standard deviation for the “need for recovery scale”, standardised beta coefficients for the 10 psychosocial job factors, significance of the coefficients, and R² of the regression model.
