Cognitive emotion regulation questionnaire in hypertensive patients

To examine the reliability,validity,and practicability of Cognitive Emotion Regulation Questionnaire (CERQ) in hypertensive patients in China.

Altogether 434 hypertensive patients and 462 healthy subjects were recruited. All the subjects were assessed with the CERQ-Chinese version (CERQ-C), Dysfunctional Attitude Scale (DAS), Mood and Anxiety Symptom Questionnaire-Short Form (MASQ-SF), and Center for Epidemiologic Studies Depression Scale (CES-D). We calculated the mean inter-item correlations for the total CERQ and for each of the subscales. Cronbach's alpha coefficient was used to analyze the inter-correlation and reliability, and confirmatory factor analysis was used to examine the 9-factor model.

1) Hypertension group reported significantly higher score than that of healthy ones on rumination (12.19 ± 2.51 vs. 11.51 ± 2.60, P<0.001), catastrophizing(8.82 ± 2.19 vs.8.11 ± 2.70,P<0.001),and blaming others(10.76 ± 2.11 vs. 9.88 ± 2.48,P<0.001), and had significantly lower score than that of healthy ones on positive reappraisal(13.80 ± 3.55 vs.14.71 ± 4.11,P<0.001).2)Reliability:In the hypertension group the Cronbach's alpha for the total CERQ was 0.80, and that for the 9 subscales ranged from 0.71 (self-blame) to 0.90 (rumination). In the healthy group the Cronbach's alpha for the total CERQ was 0.79, and that for the 9 subscales ranged from 0.71 (positive reappraisal) to 0.90 (rumination). The mean inter-item correlation coefficient for the 9 subscales was 0.21-0.42(the hypertension group)/0.19-0.32 (the healthy group). In the hypertension group,the test-retest reliability of the total scale was 0.82, the test-retest reliability of the 9 subscales ranged from 0.73 to 0.92. The confirmatory factor analysis showed that the 9 first-order factor data fitted both 2 samples well.

CERQ meets the psychometric standard and it is reliable and valid for cognitive emotion regulation strategies, which may be regarded as an appropriate assessment tool.
