Ahmet R. Özpolat, Sırrı Akbaba

Abstract


The life style scale developed by Kern in 1982 consists of five subscales and 35 items. The adaptation of the scale was made by Özpolat and Akbaba. The lowest correlation value was found to be .32 between English and Turkish items while the highest value was .92 which were found to be significant at the level of p<.05. In the reliability studies, the scale was conducted on 400 undergraduate students in Erzurum, Turkey. To find out whether the number of the subjects was adequate Kasier-Mayer-Olkin (KMO) was examined and the score was found to be .93; internal validity of the items was cronbach alpha (a) .96. In order to evaluate construct validity of the scale, principal components factor analysis was conducted, and the data was rotated in varimax. According to the results, the scale’s distribution was the same as the original one. The scale was conducted to 280 undergraduate students for the similar scale validity with the defense styles questionnaire. The correlation between total scores that subjects took was analyzed and the correlation value was found to be .69 which is significant at the level of p<.05.
