After a series of instrument development studies, a mail survey was conduct
ed with 196 randomly selected family day care providers (FDCPs) and child c
are center workers (CCCWs) residing in the state of Maryland (response rate
s were 76.6% and 70.5%, respectively). Embedded in the instrument were thre
e job stress scales, specific to child care workers, measuring job demands,
job control, and job resources. Extensive psychometric testing of the thre
e 17-item instruments demonstrated several areas of strength. The job deman
ds scale, because of its breadth of stressors covered, fared slightly worse
on indicators of reliability (alpha = 0.77; mean interitem correlation [MI
C] = 0.17; item-to-total correlations [ITCs] = 0.14 to 0.49) than did job c
ontrol (alpha = 0.88; MIC = 0.31; ITCs = 0.26 to 0.69) and job resources (a
lpha = 0.89; MIC = 0.35; ITCs = 0.32 to 0.70). Known groups validity was de
monstrated through a conceptually meaningful pattern of differences between
FDCPs and CCCWs. Construct validity for all three scales was demonstrated
by a pattern of stronger correlations with conceptually similar versus diss
imilar instruments. Average correlations with similar versus dissimilar ins
truments were: job demands, 0.54 versus 0.24; job control, 0.74 versus 0.30
; and job resources, -0.53 versus 0.30. Similar to the reliability analysis
, results of factor analysis were stronger for job control and job resource
s than for job demands.
