Abstract:
Objective:To investigate the effectiveness of suicide prevention cognitive behavioral therapy for depression patients with suicide attempt.Methods:Eligible participants were recruited from the inpatient department of Beijing Huilongguan Hospital from September 2021 to August 2022. A total of 112 patients were randomly allocated into the intervention group (56 cases) and the control group (56 cases) by a random number table. Patients in the intervention group received 12 sessions of cognitive behavioral therapy for suicide prevention over 8 weeks,while participants in the control group received supportive psychotherapy. Patient Health Questionnaire Depression Scale (PHQ-9) and the Beck Scale for Suicide Ideation-Chinese Version (BSI-CV) were used to assess changes in depressive symptoms,suicidal ideation,and suicidal tendencies in both groups at baseline,4-week of treatment,the end of treatment,and at follow-up (weekends 4,8,12). General data and scale scores between the two groups were analyzed by t test,Mann-Whitney rank sum test,and χ 2 test; repeated measure ANOVA were used to assess the baseline and intervention effects. Results:The change of PHQ-9 at each time point of the 2 groups showed a downward trend,and the group x time interaction was significant ( F=2.75, P=0.047). Since the 8th week,the PHQ score in the intervention group was significantly lower than that in the control group ( t=7.03, P<0.05). Time and group effect were significant in the four time points of the total score of suicidal ideation in the last week in BSI-CV ( F=96.78,6.35,both P<0.05),but the interaction between group and time was not significant. At weeks 8 and 12,the scores of the intervention group were lower than those of the control group ( Z=-3.11,-3.30;both P<0.01). In BSI-CV,time effects in the total score of suicidal intention was significant at four time points ( F=11.83, P<0.05),but the interaction between group and time was not significant ( F=2.56, P=0.059). There was no significant difference in suicide tendency between the two groups at each time point ( F=0.001, P=0.975). The total scores of suicidality in 2 groups at 4,8 and 12 weeks were all lower than baseline ( P<0.05). Conclusions:Compared with the control group,the cognitive behavioral therapy for suicide prevention showed superior effects on suicidal ideation and depression,but the intervention effect on suicidal tendency was not significant. Further studies are needed to investigate the long-term effects of cognitive behavioral therapy for suicide prevention in patients with depression who have attempted suicide.
