Health Effect Model (HEM) was constructed to explain the effects of mothers' caregiving to their adult children with intellectual disabilities (ID) on mothers' health. It consisted of stressors (mother's age, health problems, and socioeconomic status, co-residency and independent living capacity of the child with ID), resources and appraisals (support resources, caregiving burden, and caregiving satisfaction), and health outcomes. Many studies have used one-dimensional concept of health to measure health by asking the question, "How do you feel about your health in general?" with possible ordinal response categories of excellent, very good, good, fair, and poor. The Medical Outcomes Study has developed the 36-item instrument to measure the physical and mental components of health (PCS and MCS scores ranging from 1 to 100.) This study was to determine the variance of health explained by using the single- and the multiple-item measures in HEM, using the Structural Equation Modeling (SEM) technique. The sample consisted of 108 mothers who were 55 years or older and recruited from southwest suburbs of Chicago. The validity and reliability of the survey instrument were acceptable and the mail-out and the mail-back method were used. When the one dimensional concept of health was analyzed by SEM, its R2 was merely 0.08 with two pathways: mother's age and health problems. When PCS and MCS were analyzed using SEM, the R2 for PCS was .34, more than four fold increase with five significant pathways: mother's age, health problem, caregiving burden and satisfaction, and mental component of health. Increase in R2 seems to be related to interval scale nature of PCS measured from multiple items. Thus, multiple items to measure health are recommended if SEM is to be used.
