Abstract

OBJECTIVE:

Uncontrolled stress can lead to poorly controlled upsurges of cortisol and deregulation of the hypothalamus pituitary-adrenal axis (HPA), thereby leading to major depression. Psychoneuroimmunology (PNI) is the area of medicine dealing with the bidirectional pathways connecting the influences of brain, neuroendocrine, and immune system. Individual PNI-based lifestyle interventions such as humor and guided imagery have been shown to modulate the stress response. However, researchers have not examined the composite effect of a PNI-based lifestyle intervention among clinically depressed adults.

METHOD:

This randomized interventional study examined the composite effect(s) of a PNI-based lifestyle intervention: progressive muscle relaxation, spiritual guided imagery, and humor as an adjunct therapy to modifying the progression of depression. Forty-one participants recruited from doctors' offices in San Bernardino and Riverside counties in Southern California, were randomized into two groups: treatment (N = 20) and control (N = 21). For a period of three weeks, participants in the treatment group listened to a 12-minute progressive muscle relaxation and spiritual guided imagery CD daily and watched 10 minutes of humorous DVDs. Participants in both groups were also receiving cognitive behavioral therapy and pharmacotherapy.

RESULTS:

Depression, spirituality, humor, and stress were assessed at baseline and week 3. Depression significantly decreased from severe to mild from baseline to week 3 in the treatment group. Spirituality significantly increased in the treatment group but remained unchanged in the controls.

CONCLUSIONS:

These findings offer depressed patients alternative approaches to preventing complications and managing their illness in the context of whole-person lifestyle optimization and integration of mind-body-spirit.
