One-way ANOVA results for means both groups statistically significantly different, except latency disturbance dimensions PSQI. Participants who married more likely (OR: 1.408, 95% CI: [1.10, 1.80]), daytime 1.560, [1.27, 1.92]) develop attitudes 2.497, [1.65, 3.80]) unmarried. analysis showed that odds developing DBAS participants but bigger unmarried 1.548 3.991, respectively.), while there no significant differences 0.738, p = 0.050).
