Reliability and validity of the Turkish version of the Florida shock anxiety scale

Abstract

The aim of the study is to translate the Florida Shock Anxiety Scale (FSAS) into Turkish and probe the reliability and validity of this scale in a Turkish sample of Implantable Cardioverter Defibrillator (ICD) patients. The current study is a methodological cultural adaptation study. The Florida Shock Anxiety Scale was developed to measure fear associated with ICD shocks. The FSAS is composed of 10 items and originally was validated with two sub-factors. The current study was conducted in two different university hospital cardiology clinics in İzmir. One hundred and fifteen ICD recipients completed the FSAS. Content validity was evaluated with opinions of nine experts and between expert opinions about items of the scale was not found to be statistically significant different (p= 0.066), indicating agreement about relevant content. At the end of the confirmatory factor analysis it is concluded to use a one factor model. The factor loads of the items were found between 0.27 and 0.78. The correlation coefficient of the scores of each item and the scale score was r=0.37 - 0.77. Cronbach’s alpha coefficient was found as 0.83. Pearson’s correlation value was found as r=0.903 in retest (p= 0.000). Overall, results revealed that Turkish version of FSAS is a reliable and valid instrument in a Turkish sample.
