Psychometric Properties of the Turkish Version of the Environmentally Desirable Responding Scale (EDRS)

This study was aimed to test the reliability and validity of the Turkish version of the Environmentally Desirable Responding Scale (EDRS). The EDRS contained 18 items, which were expressed on a 4-point Likert scale. The study group consisted of 221 recreational outdoor sports participants from Ankara, Turkey. The participants included 78 females and 143 males, with a mean age of 23.2 years and a standard deviation of 3.92 years. Principal Axis Factoring (PAF) produced a 3-factor solution with the sub-dimensions self-deception/denial of negatives, image management and self-deception/assertion of positives. Confirmatory factor analysis (CFA) confirmed this 3-factor solution, AGFI=0.87, GFI=0.90, NFI=0.91, CFI=0.96, RMSEA=0.061 SRMR=0.053. Cronbach's Alpha coefficient values for 3 sub-dimensions ranged from 0.74 to 0.87. These suggest that the Turkish version of the questionnaire is a valid and reliable data collection tool for recreational outdoor sports participants.
