Self-Relatedness and Environment-Directedness Scales: Validity and Reliability Study

The aim of the present study is to conduct the adaptation study of the self-relatedness and the environment-directedness scales into turkish and to examine their psychometric properties. the data of the study have been gathered from three different study groups. the sample of the first group consists of 307 university students (231 females; 76 males). the construct validity, criterion validity, and reliability of the scales were tested using the data collected from these participants. the second group is composed of 26 university students (17 females; 9 males) in the sample, and linguistic equivalence was examined using this data. finally, the sample of the third group consists of 40 participants (20 females; 20 males), and the test-retest reliability analysis was conducted using this sample’s data. according to the exploratory factor analysis (efa), each scale was revealed to have one dimension. the findings from the confirmatory factor analysis (cfa) showed the construct validity of the self-relatedness scale had been provided, while the construct validity of the environmentdirectedness scale was not. as such, the self-relatedness scale has been adapted and translated into turkish. however, validity and reliability analyses of the environment-directedness scale need to be repeated by studies that can be carried out with university students. in addition, the correlation coefficients showing the relationship between these scales and the equivalence of the measurement instruments have proven the equivalence validity for both scales to have been satisfied. according to the results from the reliability analyses, the values for cronbach’s alpha of internal consistency were calculated as .90 for the self-relatedness scale and .92 for the environment-directedness scale. in the test-retest results, the relevant values were found as .87 for the self-relatedness scale and .78 for the environment-directedness scale. thus, both scales may be considered reliable. all the obtained findings are discussed in light of the relevant literature.
