Abstract

Objective To investigate the sleep quality of secondary insomnia patients with pregnancyinduced hypertension and its relation with their mental health to provide the references to do psychological treatment for those patients. Methods Pittsburgh Sleep Quality Index (PSQI) and the Symptom Checklist (SCL-90) were applied to investigate the sleep quality and mental health in 336 cases of secondary insomnia patients with pregnancy-induced hypertension. The correlational and regressive analyses were used to analyze the data.Results The total PSQI average scores of those patients are(13.12±3.26). According to the criteria of PSQI of poor quality of sleep (>7),there were 316(94.04%) patients suffering from the poor quality of sleep. All patients suffered sleep disorder. 138 (41.07%) ones suffered from insufficient sleep. 175 (52.21%) ones suffered from the lower sleep efficiency. 272(81.1%) ones suffered from difficulty of falling sleep. Correlation analysis results: the correlation between PSQI total score and the SLL-90 total score is up to 0.40 (P<0.01).In addition, all factors of SCL-90 except terror were significantly and positively correlated to PSQI total scores,in which the correlation coefficient between somatization factor and PSQI total scores was as high as 0.40 (P<0.01). Furthermore,the correlation coefficient between sleep disorder in PSQI and somatization was 0.46.(P <0.01). Conclusion The correlation between the sleep quality and psychological factors, especially the symptoms of somatization is significant. Thus, some psychological treatments can be adopted to treat somatization in clinical practice.
