Description: The direct effect of spouse presence during graded exercise testing on anxiety and performance has not been previously delineated. Therefore, the purposes of this study were to (a) ascertain if spouse presence during graded exercise testing affects state anxiety or physiological performance variables, and (b) determine differences in psychological status between cardiac patients and healthy adults.

Forty male and female cardiac patients and healthy adults were randomly assigned to spouse absent (N = 20) and spouse present (N = 20) conditions during treadmill testing. Each subject initially completed self-report forms measuring trait anxiety, mood state, health locus of control, and marital adjustment. State anxiety was assessed immediately before and after performing a symptom-limited graded exercise test. Physiological parameters included angina rating, blood pressure, heart rate, and metabolic measurements.

A MANOVA (p $<$.01, one-tailed) was performed to assess differences between cardiac patients and healthy adults in spouse absent and spouse present conditions for psychological and physiological variables. Independent sample t tests (p $<$.01, one-tailed) were calculated to determine psychological differences between cardiac patients and healthy adults.

In general, no differences were noted between cardiac patients and healthy adults on psychological or physiological parameters that can be attributed to spouse presence. Cardiac patients were found to have lower vigor (mood state) scores than healthy adults and a health locus of control that is predominantly powerful other external in orientation. In the context of this study, the following conclusions were made: (1) Mere spouse presence in an observational role during graded exercise testing may not affect state anxiety levels or physical performance variables. (2) Although adverse changes in anxiety levels, tension, and depression may occur as a result of a cardiac event, these changes are not dramatically apparent following one year participation in a cardiac rehabilitation program.
