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.
