Health Belief Model:
Compliance if:
|
-possess minimal levels of relevant health
motivation/knowledge
-perceive
themselves as potentially vulnerable (susceptible)
-view
disease a severe
-are
convinced that the preventive regimen is effective (benefits)
-see few
difficulties/barriers in regimen (costs)
-internal/external cues that associate with
health-related action are
considered necessary
|
Validity of HBM
|
-studies shown capacity of this
instrument to predict acceptance/rejection of preventative health
recommendations
-tendency
to comply with period of acute illness
-very
few studies linked to adherence with chronic sufferer
-Bond
et al. (1992)
|
Threat of HBM:
|
-person’s perceived risk to
function
-not
associated with good compliance but interacted with benefits-costs
-high
threat: benefits: cost have little impact upon compliance; may reduce benefits
of a recommended medical regimen, conversely.
-low
threat: strong positive effect of benefits-cost; model needs modification if to
be used with chronic ill clients
|
Cues of HBM:
|
-willingness to seek help or
medical treatment when four symptoms (cold sweats, vomiting, sob, and inability
to concentrate) experienced
-closely
related to adherence
-may
be more inclined to reflect self-efficacy
|
Benefit Cost of HBM:
|
-perceived effectiveness & few
difficulties in understanding program à
positively related with both questionnaires and measurement of compliance
|
Low benefit cost of HBM:
|
minimal perception of effectiveness
and there are difficulties; threat/risk to survival is related positively to
compliance
|
High benefit cost of HBM:
|
regimen has been accepted but there
are major hurdles for client; threat had a negative relationship with
compliance; fear that they are highly vulnerable to disease…must use fear
control to reduce emotional reactions to the threat then danger control to
reduce threat. FC and DC compete, lowering compliance
|
Severe Illness and HBM:
|
-negative relationship to
compliance with demanding regimens; chronic illnesses: threat can’t be removed
|
Metabolic Control and HBM:
|
-blood glucose levels, high threat
and high cues (overt symptoms) (poorest relationship); lack of metabolic
control may cause clients to perceive threat and cues; increased risk for
psychosomatic symptoms
|
Age factors example and HBM:
|
-diabetes: adherence decreases with
age; positively associated with two variables; cues to action and perceived
benefits-cost of the diabetic regimen
|
Theory:
|
-both focus of theoretical constructs that are
concerned with individual motivational factors and determinants of the likelihood
of performing specific behaviors
|
TRA (theory reasoned action)
|
-measures attitude and social normative perceptions that
determine behavioral intention. BI in turn affects behavior. Concerned with
relationship between beliefs, attitudes, intentions, and behavior
-provides
excellent account of volitional behaviors in an effort to predict intentions
that are not completely under volitional control
-Intention=Behavior
-intent is
equivalent to the willingness to perform the behavior
|
TRB (theory reasoned behavior)
|
-extension of the TRA, but includes additional construct
concerned with perceived control over performance of the behavior
-refers to
one’s perception of control over behavior; assumed to reflect the obstacles
that one encountered in past behavioral performances. Proposes that perceived behavioral
control can influence behavior directly
-Albarracin
et al. 2001
|
5 theories that can influence a behavior:
|
-intention, attitude toward behavior, subjective norm,
perceived behavioral control, behavior normative & control beliefs.
|
Subjective norm:
|
-normative belief that referent should or should not perform
the behavior
-motivation
to comply with the referent and number of referents
-normative
beliefs are bipolar in nature and motivations are unipolar
