Healthy patients who perceive poor health: why are they worried sick?

OBJECTIVE

To explore characteristics of patients who are physically healthy but who perceive poor health by investigating the hypothesis that mental health problems, financial strain, and deficiencies in social support underlie why these patients are "worried sick."

METHODS

Three hundred forty-eight continuity patients in 2 rural primary care practices were administered the PRIME-MD, the MOS SF-36, a health-related worry (1-item, 5-point) scale, the MOS social support survey, and perceived economic strain instruments. The patient's physician rated physical health on a 10-point scale. Health care utilization was defined as the number of office visits and total office and laboratory charges for 6 months before and after the interview date.

RESULTS

Two hundred thirty-seven patients (group A) scored in the upper and middle terciles on the MOS health perceptions scale. One hundred eleven patients scored in the lower tercile on health perceptions: 59 (group B) were rated as having good physical health (physical health rating > 6) and 52 (group C) as having poor health (rating < or = 6). The "worried sick" patients (group B) resembled Group A with regard to physical health, but resembled the sick (group C) with regard to all MOS functional scales, prevalence of mental health diagnoses, and worry. Social support was similar across groups. Only 1 of 3 measures of economic strain was less in group A than B and C.

CONCLUSIONS

Our measures of mental health problems, financial strain, and deficiencies in social support accounted only in part for the differences among the three groups. Other explanations of why some are "worried sick" require study, such as other life stressors and personality traits.
