Percent of PCAP GAD Patients Without Comorbid Axis I Disorders and Without Medical Illnesses (n = 20) That Scored Below the 25th Percentile on the SF-36 Relative to General Population and Medically Ill Samples^a

Reference Sample	Physical Component Summary score, %	Score of the 25th Percentile for the Comparison Group	Mental Component Summary Score, %	Score of the 25th Percentile for the Comparison Group
General populationb	35	42.83	75	45.03
Diabetesc	10	33.38	90	48.07
Recent myocardial infarctionc	15	36.32	90	47.39

Congestive heart failurec	5	25.44	75	45.03
Depressionc	15	36.57	5	25.60

^aAn entry of 25% reflects equivalence between the 2 samples. A higher percentage indicates that more PCAP pure GAD patients were at the comparison sample's 25th percentile level. A lower percentage indicates that fewer PCAP pure GAD patients were at the comparison sample's 25th percentile level.

^bGeneral population sample from the 1990 National Survey of Functional Health Status.³²

^cMedically ill samples from the Medical Outcomes Study.³¹
