Turkish Adaptation of Basic Psychological Needs For Energy Conservation: Reliability and Validity Study
In this study the Basic Psychological Needs for Energy Conservation Scale developed by Sweeney, Webb, Mazzarol and Sautar (2014) was adapted to Turkish by ensuring its validity and reliability. Pilot study and main study were conducted with two different samples. Pilot study consists of 172 preservice science teachers and main study consists of 1136 preservice science teachers. While adapting the scale to Turkish, content and construct validity along with back-to-back translation were achieved. In terms of construct validity exploratory factor analysis and confirmatory factor analysis were applied to different samples to test the structure of the scale. Both analyses revealed that the scale has two factors: autonomy/competence and relatedness. The desired goodness of fit values was attained for CFA. In order to address the reliability of the scale, item analysis, Cronbach Alpha reliability and item-total correlation analysis were conducted. All these analyses confirmed the reliability of the scale. All of the validity and reliability analysis revealed that Turkish version of Basic Psychological Needs for Energy Conservation Scale is valid and reliable, and it can be used for further studies.
