Emotional task is one of the main methods to study the attention bias and emotional function of affective disorder.Functional near-infrared spectroscopy(fNIRS)studies based on emotional tasks in patients with affective disorders have shown that facial emotion recognition task,the emotional stroop effect,and the emotion induction task combined with fNIRS technology have clinical value in the diagnosis and treatment of affective disorders.The defects of attention function and emotional processing in patients with affective disorders are related to abnormal activation of the left prefrontal cortex,especially the differences in brain activation patterns are related to depressive symptoms in patients with depressive disorders.The future direction of using fNIRS to study emotional tasks is to combine a variety of neuroimaging methods to conduct large-sample longitudinal cohort studies to obtain more objective bases for diagnosis and treatment,and to compare the differences in activation areas of different emotional stimulation materials.

Objective:To explore the application effect of parent-child emotional regulation and resilience group training in adolescent depression patients.Methods:From August 2020 to September 2021, a total of 118 adolescent depression patients were enrolled and randomly divided into the intervention group(66 cases) and the control group(66 cases) by a random number table method.The intervention group received medication therapy and parent-child group emotional regulation and psychological resilience training, while the control group received medication therapy and commonly used individual, family or group therapy in clinical practice.The Hamilton Depression rating scale(HAMD-24 version), Herth hope scale(HHS), Connor-Davidson resilience scale(CD-RISC), and family adaptability and cohesion evaluation scale, second edition Chinese version(FACES-Ⅱ-CV) were adopted to investigate participants at baseline, 12-week, 24-week, and 36-week after intervention.SPSS 26.0 statistical software was used to perform repeated measurement analysis of variance on the data.Results:(1)The interaction effect between two groups of HAMD scores( F=54.0, P<0.001), group main effect( F=401.4, P<0.001), and time main effect( F=116.6, P<0.001) were all significant.Further simple effect analysis showed that there were statistically significant differences in HAMD scores at various time points after intervention between the intervention group(26.2±6.5, 19.3±5.9, 11.3±5.6) and the control group(33.1±9.1, 30.3±7.9, 25.0±8.4)(all P<0.05). Intragroup comparison showed the HAMD scores of the intervention group and control group at each time point after intervention were lower than those before intervention (all P<0.05). (2)The interaction effect of CD-RISC scores between two groups of patients( F=72.1, P<0.001), group main effect( F=48.9, P<0.001), and time main effect( F=174.9, P<0.001) were significant.Further simple effect analysis showed that the CD-RISC score of the intervention group at each time point after intervention were higher than those of the control group(all P<0.05). Intragroup comparison showed the scores of CD-RISC at each time point after intervention in the intervention group and the control group were higher than those before intervention(all P<0.05). (3)The interaction effect of HHS scores( F=121.6, P<0.001), group main effect( F=57.4, P<0.001), and time main effect( F=208.1, P<0.001) of the two groups of patients were significant.Further simple effect analysis showed that the HHS scores of the intervention group were higher than those of the control group at all time points after intervention(all P<0.05). Intragroup comparison showed the HHS scores of the intervention group and the control group at each time point after intervention were higher than those before intervention(all P<0.05). (4)The interaction effect of FACES-Ⅱ-CV scores( F=45.0, P<0.001), group main effect( F=20.3, P<0.001), and time main effect( F=154.5, P<0.001) of the two groups of patients were significant.Further simple effect analysis showed that the FACES-Ⅱ-CV scores of the intervention group were higher than those of the control group at all time points after intervention(all P<0.05). Intragroup comparison showed the FACES-Ⅱ-CV scores of the intervention group and the control group at each time point after intervention were higher than those before intervention(all P<0.05). (5)The total effective rate of the intervention group was higher than that of the control group(95.1%, 87.7%)( P<0.001). Conclusion:In adolescents with depression, parent-child group emotional regulation and resilience training can effectively reduce depression emotion, increase the level of hope and resilience of patients and enhance family intimacy and adaptability.
