This study aims to adapt the Core Life Activities Scale (CORE) into Turkish and evaluate its validity and reliability in Turkish-speaking adults. The CORE is a five-item self-report scale that assesses five basic areas of daily life: eating, sleeping, physical activity, learning new things, and social relationships. Approximately 300 adults aged 18 years and older will participate in the study. Participants will complete the Turkish version of the CORE together with measures of health-related quality of life. The CORE will also be administered again one week later to evaluate test-retest reliability. The findings will determine whether the Turkish version of the CORE is a valid and reliable tool for assessing core life activities in Turkish-speaking adults.

Primary outcome measure(s)
Internal Consistency of the Turkish Core Life Activities Scale — Baseline Internal consistency of the Turkish version of the Core Life Activities Scale (CORE) will be evaluated using Cronbach's alpha coefficient. The CORE consists of five items assessing eating, sleeping, physical activity, learning new things, and social relationships, with each item rated on a 5-point Likert scale from 1 (never) to 5 (always).
Test-Retest Reliability of the Turkish Core Life Activities Scale — Baseline and 1 week Test-retest reliability of the Turkish version of the CORE will be evaluated by comparing CORE scores obtained at the initial assessment with scores obtained one week later. The association between the two assessments will be examined to determine the temporal stability of the scale.
Construct Validity of the Turkish Core Life Activities Scale — Baseline Construct validity of the Turkish version of the CORE will be evaluated by examining its relationships with health-related quality of life measures assessed using the 12-Item Short Form Health Survey (SF-12) and the World Health Organization Quality of Life-BREF (WHOQOL-BREF).
