Do working characteristics influence the participation at health measures? Findings from a trial phase of workplace health promotion

摘要

As all 33 items which have been applied to assess working characteristics could be answered on a four-staged scale (1“no”; 2”rather no”; 3”rather yes”; 4“yes) and are therefore not interval-scaled, it was necessary to recode them into binary variables for statistical analysis. The individual assessment of work characteristics on the basis of those items can theoretically be divided in four dimensions: work demand, work amount, social climate, and environmental aspects. Confirmatory factor analysis was used to verify presumed dimensionality and confirmed acceptable internal consistency for work amount (6 Items; α = 0.77), work demand (11 Items; α = 0.70), and social climate (12 Items; α = 0.82) but marginally acceptable internal consistency for environmental aspects (4 Items; α = 0.60). However, the environmental aspects scale only includes four items and thus reliability can be regarded as sufficient [ ].
