“Impact of Nurse-Directed Educational Intervention onKnowledge and Health Promotion Behaviours amongPatients with Sickle Cell Anemia”

Abstract

The study aimed to assess the knowledge and health promotion behavior of adolescents
regarding sickle cell anemia and to evaluate the effectiveness of a nurse-directed intervention.
Specific objectives included assessing knowledge in the experimental and control groups,
evaluating the effect of the intervention on health promotion behavior, and comparing
demographic variables with pretest scores between groups.
An interventional research approach with a quasi-experimental design was adopted at
Parul Sevashram Hospital, Vadodara. A total of 20 adolescents were selected using simple
random sampling. Data were collected through pretest and posttest assessments on
knowledge and health promotion behavior.
Findings revealed that in the experimental group, 50% of respondents had poor and
average knowledge at pretest, whereas post-test results showed 100% had average
knowledge. In the control group, 100% of respondents had poor knowledge at pretest; post-
test showed 60% attained average knowledge, while 40% remained in the poor category.
Regarding lifestyle behavioral changes, in the experimental group, 50% reported a neutral
attitude and 40% an agreeable attitude at pretest, whereas post-test results indicated 70%
agreed and 30% strongly agreed with positive health behaviors. In the control group, pretest
results showed 50% neutral, 30% agreeable, and 20% disagreeable attitudes; posttest results
indicated 50% neutral, 40% agreeable, and 10% disagreeable attitudes.
The study concludes that nurse-directed intervention was effective in improving both
knowledge and health promotion behavior among adolescents with sickle cell anemia in the
experimental group compared to the control group.
