The Polish adaptation of the blood donation fears inventory

Abstract

Background and objectivesGiven the decline in the number of voluntary blood donors in Poland and the lack of psychological research on blood donors and the donation system in the country, there is a need to develop a tool to measure barriers to recruiting new donors and retaining active donors. One significant barrier is the presence of specific fears associated with the blood donation process. Therefore, the main objective of this study was to perform the Polish adaptation of the Blood Donation Fears Inventory (the BDFI). Materials and methodsThe Polish adaptation of the BDFI was developed and tested on a sample of 409 individuals, consisting of 194 (47.5%) voluntary blood donors and 214 (52.5%) non-donors. The original tool comprises an 18-item scale that measures four different types of fears related to the blood donation process: (1) Fear of Syncopal Symptoms, (2) Fear of Blood and Needles, (3) Fear of Social Evaluation, and (4) Fear of Health Screen Results. ResultsTo determine the psychometric properties of the scale, exploratory factor analysis, confirmatory factor analysis (RMSEA =.098; CFI =.958; TLI =.935; SRMR =.035), second-order factor analysis (RMSEA =.097; CFI =.958; TLI =.936; SRMR =.036; NNFI =.936; NFI =.938), and bifactor analysis (RMSEA =.093; CFI =.969; TLI =.942; SRMR =.036; NNFI =.942; NFI =.952) were conducted. The reliability of the tool was assessed using Cronbach's Alpha and McDonald's Omega, resulting in high coefficients (ranging from.92 to.97) for each scale. Internal consistency was examined using the State-Trait Anxiety Inventory (STAI), while external consistency was examined using the Scale of Positive and Negative Experience (SPANE) and the Self-esteem Scale (SES). ConclusionSatisfactory results were obtained, establishing the Polish adaptation of the BDFI. This tool represents a novel contribution to the research on the blood donation system in Poland
