conditions and anxiety. There were 19 respondents who received mental health treatment

for anxiety (see Table 3-6 for sample characteristics).

 Results. To determine the relationship between anxiety treatment and total health

care expenditures after adjusting for demographics (age, sex, race/ethnicity),

socioeconomic status (years of education and income), insurance status, illness severity

(perceived physical and mental health status, and comorbid conditions), and depression

treatment, a log-linear multiple regression was conducted. The relationship between

anxiety treatment and total health care expenditures was non-significant (t = .91, p = .19)

(see Table 3-10). The group who had received anxiety treatment cost $5,186 more than

the group who had not received anxiety treatment.

 To determine the relationship between anxiety treatment and medical expenditures

only after adjusting for demographics (age, sex, race/ethnicity), socioeconomic status

(years of education and income), insurance status, illness severity (perceived physical and

mental health status, and comorbid conditions), and depression treatment, a log-linear

multiple regression was conducted. The relationship between anxiety treatment and

medical expenditures only was non-significant (t = .91, p = .19) (see Table 3-11). The

group who had received anxiety treatment cost $11,292 more than the group who had not

received treatment.

Anxiety Treatment and Health Care Utilization

 Using the same sample of respondents with cardiac conditions and anxiety, the

relationships between anxiety treatment and various measures of health care utilization

(number of office-based provider visits, outpatient hospital visits, inpatient nights, and

emergency room visits) were determined (see Table 3-12).
