Positive Thoughts May Help Treat Depression
Gratitude andِ optimism mayِ beِ a key toِ managing depression, a newِ review ofِ relevant research finds.
Called positive activity interventions (PAIs), theِ treatment involves intentional positive behaviors andِ thoughts, suchِ asِ performing acts ofِ kindness, expressing gratitude, meditating onِ positive feelings towardِ othersِ andِ using one’sِ signature strengths.
Although positive psychology isِ still a developing field, theِ relativelyِ small butِ growing number ofِ studies onِ PAIs areِ beginning toِ identify important mechanisms underlying theِ benefits ofِ such interventions, theِ authors write inِ a recentِ issue ofِ The Journal ofِ Alternative andِ Complementary Medicine.
Is your glass half-full?
Researchers fromِ the University ofِ California, Riverside andِ Duke University inِ Durham, N.C., analyzed results fromِ various studies onِ PAIs, including randomized, controlled studies thatِ hadِ promising initial findings whenِ patients withِ mild clinical depression practiced PAIs.
For instance, inِ a study published inِ 2010, researchers asked 220 participants, ages 20 toِ 71 years, toِ thinkِ optimistically aboutِ the future orِ write letters ofِ gratitude overِ a six-week period, whileِ theِ control group wasِ asked toِ list theirِ pastِ experiences.
The researchers note theِ advantages ofِ self-administered therapy, whichِ isِ free toِ practice followingِ the relativelyِ trivial cost ofِ initial instructions, whichِ canِ beِ attained fromِ the Internet, DVDs, workbooks, andِ even mobile phone applications.
The upside of optimism
A 2001 Johns Hopkins study ofِ 600 adults withِ a family history ofِ heart disease foundِ that individuals withِ a positive attitude wereِ halfِ asِ likely asِ their lessِ optimistic counterparts toِ experience a heart attack orِ other heart issues.
Researcher Diane Becker ofِ Hopkins suggested thatِ people withِ a sunny outlook produce lowerِ levels ofِ stress hormones, inِ effect helping toِ protect themِ againstِ disease.
A 2006 study byِ researchers fromِ Carnegie Mellon University foundِ that people whoِ areِ happy orِ exhibit otherِ positive emotions areِ less likelyِ to catch colds andِ report fewerِ symptoms ofِ the illness whenِ theyِ areِ under theِ weather.
