The effect of nurse-facilitated education using videotape prior to elective cardiac catheterization on stress and anxiety levels

Abstract

This study used a pre-test post-test experimental design to evaluate the effect of nurse-facilitated education using videotape observation on stress and anxiety levels prior to elective cardiac catheterization. Forty subjects were randomized to either a treatment or control group. The treatment group viewed a video about cardiac catheterizations while the control group viewed a video about home improvements. The State Trait Anxiety Inventory (STAI) was used to measure anxiety levels in both groups both before and after the video. S-cortisol was used to measure stress levels in both groups both before and after the video. After analysis of data, it was determined that subjects who viewed the videotape on home improvements had lower STAl scores post video than those who received information about the cardiac catheterization. No correlation was found between the STAI scores and the s-cortisol concentrations. Future studies should be performed to address the issues identified in this study
