Objective:To explore the effect of behavioral activation therapy on subthreshold depression and quality of life in patients with diabetes foot amputation, and to provide reference for clinical psychotherapy and quality of life improvement in patients with diabetes foot amputation.Methods:A randomized controlled trial was conducted to select 50 patients with diabetes foot amputation from September to December 2023 in the People′s Hospital Affiliated to Shandong First Medical University by convenient sampling. The participants were divided into an control group and a observation group, with 25 cases in each group, using a random number table method. The patients in the control group received routine nursing care of diabetes feet, and the patients in the observation group were given behavior activation therapy on the basis of the control group. The Centre for Epidomiological Studies Depression Scale (CES-D), Behavioral Activation for Depression Scale-Short Form (BADS-SF), and Short Form Health Measure (SF-12) were used to assess patients′ subthreshold depression, behavior, and quality of life before the intervention, at the end of the intervention, and 3 months after the intervention.Results:The final number of patients who completed the study in the control group and observation group were 23 and 24, respectively. There were 11 males and 12 females in the control group, with an age of (69.70 ± 7.01) years. There were 12 males and 12 females in the observation group, with an age of (69.17 ± 6.83) years. At the end of the intervention and 3 months after the intervention, the CES-D scores of the observation group were (21.13 ± 2.19) and (18.83 ± 1.86) points, respectively, which were significantly lower than those of the control group (25.70 ± 1.72) and (25.91 ± 1.65) points, and the differences were statistically significant ( t=-7.93, -13.80, both P<0.05). At the end of the intervention and 3 months after the intervention, the BADS-SF behavioral activation dimension scores in the observation group were (17.67 ± 2.41) and (18.50 ± 2.19) points, respectively, higher than the control group's (11.83 ± 1.78) and (11.57 ± 2.02) points, and the differences were statistically significant ( t=31.65, 34.45, both P<0.05). The behavioral avoidance dimension scores were (9.48 ± 1.50) and (9.65 ± 1.99) points, respectively, lower than the control group's (10.75 ± 1.42) and (11.88 ± 1.57) points, and the differences were statistically significant ( t=6.53, 13.17, both P<0.05). Three months after the intervention, the total score of SF-12 in the observation group was (65.96 ± 2.94) points, and the psychological dimension score was (37.50 ± 4.14) points, both of which were higher than those in the control group (60.30 ± 2.42) and (30.13± 5.15) points, and the differences were statistically significant ( t=51.54, 5.42, both P<0.05). There were statistically significant differences in time, between groups, and interaction effects in CES-D score, scores of two dimensions of BADS-SF and SF-12 total score ( F values were 10.04-190.71). Conclusions:Behavioral activation therapy can improve the symptoms of subthreshold depression in patients with diabetes foot amputation, enhance their behavioral activation level, and improve the quality of life to a certain extent.
