Comparative Study of Self-Demonstration Versus Video based Education on Level of Anxiety and Self-Efficacy in Patient Undergoing Cardiac Surgery: A Double-Blinded Randomized Controlled Trial
Keywords:: Cardiac Surgery, Self Efficacy, Pre Operative Education, Anxiety and Depression
Aim: To compare the effect of self-demonstration versus video based education in reducing anxiety and
improving self-efficacy of a patient undergoing cardiac surgery.
Methodology: A Double Blinded, Randomized Control Trial conducted at Dr. Vikhe Patil Memorial
Hospital. Study duration was 12 months. A total number of 58 patients were included in this study. The
patients divided into two groups. Group I which receives self-demonstration and Group II which receives
video based demonstration by simple random sampling using chit method.
Outcome Measures: Primary outcome measure is Self-efficacy questionnaire. Secondary outcome measure
is Hospital Anxiety Depression Scale.
Result: Within the group analysis, Group I and Group II showed that there was significant difference between
pre and post intervention anxiety and depression. Between the group analysis, there was no significant
difference found for anxiety (P=0.4925) and depression (P= 0.9441). In Group I and Group II there was no
statistical significant difference for Score of Self Efficacy Questionnaire (P=0.6970).
Conclusion: Our study concluded that Self-Demonstration and Video Based Education both are equally
effective in reduction of anxiety. Similarly the study supports equal effectiveness of above techniques in
term of self efficacy post operatively.
