For finding Test-Retest reliability they refilled ISI questionnaire 2 weeks later.

Results

Cronbach-α coefficient of C-ISI for the clinical group, control group and both of them was 0.72, 0.75 and 0.91 respectively. The C-ISI component and total scores in test were significantly correlated with their related components and total scores in re-test (P < 0.05). Mean Ranks for All C-ISI components, total score were significantly higher in clinical group than control group that presents low sleep quality in clinical group. There are Significant correlations between C-ISI component and total scores and C-PSQI components and Total scores in related Items.
