Although perceptions of internal control have been related to physical and
psychosocial outcomes in chronic illness, less attention has been pain to p
erceptions of external sources of control and their implications for adapta
tion. One reason for this has been the dearth of adequate measures for asse
ssing specific external control constructs. The God Locus of Health Control
(GLHC) scale was developed to assess the extent of an individual's belief
that God controls his or her health status. The GLHC was designed as an adj
unct to the widely used Multidimensional Health Locus of Control (MHLC) sca
les. Initial studies of the psychometric properties of the CLHC scale in sa
mples of persons with two rheumatic diseases, rheumatoid arthritis and syst
emic sclerosis, provide evidence of the scale's reliability and validity.
