Patients participating
in "motivational" interviews soon after a stroke show fewer
signs of depression and increased survival
Patients who received several sessions of
a "motivational interview" early after a stroke had normal
mood, fewer instances of depression and greater survival rates at
one year compared to patients who received standard stroke care,
according to new research reported in Stroke: Journal of the American
Heart Association.
Motivational interviewing is generally a talk-based therapy for
patients with health problems that require behavior change, but
in this study it was used to support adjustment to life after stroke.
Depression is a common problem after stroke that interferes with
recovery, survival and return to normal participation in life.
After one year, 48 percent of patients who had the early, talk-based
therapy had normal mood, compared to 37.7 percent of patients who
did not have the therapy.
Furthermore, the death rate among the intervention group was 6.5
percent compared to 12.8 percent in the control group.
Unlike previous post-stroke talk and drug therapy studies, researchers
began the study within one month of patients suffering a stroke.
"Prior studies targeting depressed stroke patients have had
limited success, but the depression may have already interfered
with rehabilitation and recovery," said Caroline Watkins, Ph.D.,
lead author of the study and professor of Stroke and Older People's
Care at University of Central Lancashire in England. "We found
that early intervention helped people set realistic expectations
for recovery, avoid some of the misery associated with life after
stroke, and may even help them live longer."
The study involved 411 patients in a hospital's stroke unit. The
patients were on average 70 years old and slightly more than half
were men. They weren't moving out of the area after discharge; were
not receiving psychiatric or clinical psychology intervention; and
were without severe cognitive or communication problems preventing
participation in interviews.
The researchers assessed patients' mood, beliefs and expectations
for recovery and activities of daily living using standard questionnaires.
All patients received usual stroke care and half were assigned randomly
to one therapist for up to four 30- to 60-minute sessions of the
talk-based therapy within two to four weeks of suffering a stroke.
Therapists asked the patients their thoughts about the future,
what hurdles they expected to face in recovery and how confident
they felt about approaching these hurdles. Therapists encouraged
patients to identify their own solutions to problems they anticipated.
The therapists weren't trained clinical psychologists - two were
nurses and two had psychology degrees. But all were trained and
supervised by a clinical psychologist, suggesting that the program
could be replicated easily in a variety of healthcare settings with
proper supervision.
Patients were assessed again at 12 months via mailed questionnaires.
"While a higher percentage of patients in the control group
had died after 12 months, we did not study the cause of death of
every patient," Watkins said. "These results imply a strong
association between mood following a stroke and mortality within
one year, but we believe it should be examined in a much larger
study."
The study also didn't include patients with severe communication
problems because it would have been difficult for them to participate
in talk-based therapy.
Furthermore, researchers conducted the study in one hospital, where
the training and supervision of therapists was tightly controlled.
It's unclear if the same effects would be seen in less controlled
settings, researchers said.
"The simplicity and brevity of this intervention makes it
inexpensive to deliver, and yet it has the potential to give huge
benefits to its recipients," Watkins said. "It's imperative
that further research is supported to ensure effective methods of
implementation are developed."
