(a–h) PSQI scores in alcohol‐dependent patients and healthy controls. (i, j) The correlation between the PSQI score and the AUDIT score. Alcohol‐dependent patients committed higher scores than controls in sleep efficacy and total score. Correlation analysis revealed significant positive correlations between the PSQI and AUDIT score in alcohol‐dependent patients (i, r = .7695, p = .0008). With regard to the controls, no significant correlations were detected between PSQI score and AUDIT score [Color figure can be viewed at http://wileyonlinelibrary.com]
