Background
Many psychological studies have been conducted to examine the role of personality
in physical health. Locus of Control, (LOC) is a personality construct
that has been found to play a major role in physical health. Locus
of Control refers to the beliefs a person has about their control over
different situations, either external or internal. People who have
a more internal locus of control believe they are responsible for their
experiences and have the power to change their own situations through their
actions. External individuals feel they have very little control,
if any, over changing their situation (Lefcourt, 2000). Patients
deal with physical illness differently depending on whether they are more
internal or external. As the definition of the two types suggests,
the external individuals deal passively with their illness, putting the
control in something or someone other than themselves. Internal individuals
take a more active role by performing health behaviors beneficial to their
recovery (Lefcourt, 2000). In patients with chronic illness, the
relationship between locus of control and physical health is the most apparent.
In chronic illness, performing health behaviors are critical in maintaining
optimum health. Therefore, it is necessary for chronically ill patients
to adopt a more internal locus of control in order to more effectively
deal with their disease and maintain better physical health.
One study in particular that examined the effects of locus of control on
the physical health of chronically ill patients was done by Wallhagen and
Brod in 1997. They investigated the interrelationships between perceived
control and well being in Parkinson's patients. Results indicated
that the degree of control they felt they had over their disease was significantly
related to the patient's well being. For each point increase in LOC
(more internal), there was almost a three point increase in patient well
being (Wallhagen & Brod, 1997). This study provides support for
the idea that in chronically ill patients, the locus of control of the
patient is strongly associated with the patient's physical well being.
The current study examines this same relationship in students with asthma,
another form of chronic illness.

Research Question
The purpose of the current study was to 1) determine if the chronically
ill sample, those suffering from asthma, differ in the mean degree of internality
when compared to the control group, 2) determine if the control group differs
from the asthmatic group in their ratings of physical health, and 3) determine
if a relationship exists between locus of control and physical health and
see if there is a difference between the two groups.

Method
Participants
in the current study were recruited from a small, Catholic, liberal
arts college in the northeast. There were twenty- four participants
in all, eleven were diagnosed with asthma and thirteen without a diagnosis
of asthma. Within the asthma group there were five males and six
females and within the non- asthma group there were seven males and
six females. The participants ranged in age from 18 to 22 years
old. The materials used were the revised Locus of Control
and Attributional Style Inventory (Jerabek, 2000) and the Physical Health
Inventory (Morrison, 2000). The revised Locus of Control and Attribution
Style Inventory was used to measure the degree of each participant's
locus of control, either internal or external, on a scale from 0 to
100. The higher the score, the more internal and the lower the
score, the more external the individual. The Physical Health Inventory
consisted of ten questions, all Likert scale, to determine each participant's
physical health based on their perception of factors such as sleep,
exercise, and diet. The possible scores for the Physical Health Inventory
range from 10 to 50, the higher the score, the higher the individual's
physical health and the lower the score, the lower their physical health.
The participants were asked to complete one of each inventory and their
scores were analyzed using a computerized statistics program.

Results
Finding one of the study revealed there was a significant difference between
the groups for locus of control. The asthma group displayed a higher
locus of control compared to the non- asthma group. Finding two found
that a significant difference in physical health existed between the two
groups with the non- asthma group possessing better physical health than
the asthma group. The third finding of the study revealed that within
the asthma group, there was in fact a significantly positive relationship
between locus of control and physical health. No such relationship
existed between locus of control and physical health within the non- asthma
group.

Implications
The current study found a significant positive relationship between locus
of control and physical health in chronically ill participants.
The implications of this finding are to somehow enhance internal locus
of control in chronically ill patients so they will more efficiently manage
their disease and maintain optimum health. Due to the nature of chronic
illness, the patient is responsible for a majority of their care.
Having internal locus of control enables the patient to feel more confident
in managing their disease rather than someone who is more external and
relies on others for their care. One way in which chronically ill
individuals could increase their internal locus of control and therefore
manage their diseases more efficiently would be self- efficacy training.
Self- efficacy is the confidence one has in oneself to complete a task
(Lefcourt, 2000). Self efficacy training could be done individually
or in groups either by medical professionals or psychologists. The
training would teach patients how to be more confident in caring for themselves,
teach them to readily recognize symptoms, and perform certain tasks specific
to their disease. Another way to increase self efficacy or internal
locus of control in the patient is to encourage them to participate in
choosing their own treatment plan and to gain further knowledge about their
disease by asking questions and doing their own research. The current
study, along with many previous studies in the same area, all suggest the
need for an increase in the internal locus of control for chronically ill
individuals. These types of studies also stress the importance of
further research in the area of health psychology and specifically the
needs of the chronically ill population.
