A comparison of contribution of informed consent forms with long or short texts with regard to obtaining knowledge by volunteers: A pilot study

摘要

Objective. The objective is to determine which of the two texts giving information about the same issue and one of which id short and one of which is long is more effective in enlightening readers having no pre-knowledge of medical science and whether there is coherence between the scores obtained from the texts. Methods. The sampling of the research planned as experimental is constituted by 66 volunteer female students who are 1st year students at the faculty of agriculture. The group was randomly divided into two and the first group was given the short text and the other one the long text. Then the question from was applied in order to find out how much of the information in the form they learnt. Each true answer given to the questions was scored as 1, and each wrong answer was secored as 0; therefore a total grade was obtained. For data analysis, Mann Whitney-U and t Tests analysis methods have been used. Score averages have been compared using Chi-square statistics and calculated using Odds ratio (OR). Consistency between the average scores of the answers given to short and long forms were evaluated through kapa statistics. Results. 100% of the answers obtained using the long form was above the average, 20% of the answers obtained using the short form was above the average and 80% was below the average. Kappa between the answers in the long and short from was found as 81%. The results obtained from the long form were determined to be seven times better than the short one (OR:7,0). The non-random alignment between responses to the long and short form was found to be 81% (Cohen Kappa: 0.814). When the score average scores obtained from the answers given according to the demographic qualities of the participants, no meaningful relation was found. Conclusions. The long version of the context of informed was found more effective than the short one.
