Adaptation of the Couples' Sleep Conflict Scale into Turkish.

The Turkish adaptation of the Couples' Sleep Conflict Scale retained a 5-item, single-factor structure across female, male, and total groups.

• Exploratory factor analysis confirmed the scale consists of 5 items and one sub-dimension
• The single-factor structure was consistent across female, male, and total groups
• The cultural adaptation process was completed in three stages: language validity, content validity, and piloting

Confirmatory factor analysis indicated acceptable model fit for the Turkish version of the Couples' Sleep Conflict Scale across all groups.

• Confirmatory factor analysis was applied to determine construct validity
• Scale items were determined to have an acceptable level of fit for each group (female, male, and total)
• Both exploratory and confirmatory factor analyses were used to evaluate construct validity

The Turkish Couples' Sleep Conflict Scale demonstrated high internal consistency reliability across all groups.

• Cronbach's alpha for the female group was 0.838
• Cronbach's alpha for the male group was 0.827
• Cronbach's alpha for the total group was 0.835
• All values are described as 'high Cronbach Alpha values'

Test-retest analysis demonstrated high temporal stability of the Turkish Couples' Sleep Conflict Scale.

• High correlation values were observed in the test-retest analysis
• Test-retest analysis was conducted as part of the reliability analyses alongside Cronbach's alpha
• Specific correlation coefficients and time interval between test and retest are not reported in the abstract

The study used a cross-sectional, methodological research design to validate the scale in a Turkish population of married individuals.

• The study is described as 'methodological research conducted using a cross-sectional design'
• The target population was married individuals in the Turkish population
• Analyses were conducted separately for female, male, and total groups
• Sample size is not reported in the abstract
