Abstract
This study aims to adapt the Engaged Living Scale (ELS) to Turkish culture and assess its validity and reliability. The study's population sample consists of 317 people, 216 women (68.1%) and 101 men (31.9%) between the ages of 18 and 61 (30.87±10.27). A group of 43 psychology students was given the test-retest application at a three-week interval. The Acceptance and Action Questionnaire-II (AAQ-II), Valuing Questionarre (VQ), Psychological Flexibility Scale (PFS), Valued Living Questionnaire (VLQ), and Satisfaction of Life Scale (SLS) were administered to 191 people out of 317 for convergent validity. It was found high test-retest correlations (between .82 and .83) and Cronbach α internal consistency values (between .86 and .91) in the study. Convergent validity analyses were performed on the AAQ- II, VQ, PFS, VLQ, and SLS, and weak but statistically significant correlations ranged from .15 to .26 were determined. There were also statistically nonsignificant correlations between the ELS and some of the convergent validity subscales. The fit indexes were found to be acceptable after the suggested modifications to the confirmatory factor analysis were made within the scope of construct validity. This study aims to adapt the Engaged Living Scale (ELS) to Turkish culture and assess its validity and reliability. As a result, it can be said that is the ELS, a valid and reliable scale with strong psychometric properties as well as can use in research studies.
