摘要
目的探究老年抑郁症患者的跨期决策功能及与冲动性人格特征的关系。方法共纳入40名老年抑郁症患者（老年抑郁组）以及40名人口学资料相匹配的健康自愿者（健康对照组），采用延迟折扣任务（delay discounting task，DDT）评估决策功能、Barratt冲动性量表评估冲动性人格。结果老年抑郁组延迟折扣率（k）的常用对数（lgk）、Barratt冲动性量表总分、注意冲动性及行动冲动性分量表得分[分别为（-2．00±0．81），（42．67±8．51）分，（46．50±16．84）分，（43．50±10．45）分]显著高于对照组[分别为（-2．31±0．51），（32．27±6．18）分，（34．81±8．15）分，（26．88±7．65）分]，差异有统计学意义（t=2．060，P=0．043；t=6．252，P〈0．01；t=3．951，P〈0．01；t=8．117，P〈0．01）。老年抑郁组lgk值与行动冲动性分量表得分呈正相关（r=0．408，P=0．009）。结论延迟折扣能力在老年抑郁症患者中受损，与行动冲动性有关。
Objective To explore the intertemporal decision-making function in geriatric depressive patients and it＇ s correlation with inipulsive personality traits.Methods Fortypatients with geriatric depression（ GD group） and Forty demographic characteristic matched health controls （HC group） were recruited. The delay discounting task was used to measure the decision-making function, and the barratt impulsiveness scale was used to measure the impulsive traits. The delay discounting rate （k） transformed to common logarithm lgk.Results Lgk and the scores of barratt impulsiveness scale,attention impulsiveness subscale,m tor impulsiveness subscale in GD group（ （ -2.00±0.81 ）, （42.67±8.51）, （ 46.50± 16.84）, （ 43.50± 10.45 ） ） were more larger than those in HC group （ （ -2.31±0.51 ） , （ 32.27±6.18）, （ 34.81±8.15 ）, （ 26.88±7.65 ）, and the differences were statistically significant （ t= 2.060,P= 0.043 ; t= 6.252,P〈0.01 ; t= 3.951, P〈0.01 ; t = 8.117, P〈0.01 ）.In addition, lgk had positive correlation with the scores of motor impulsiveness factor in GD group （r= 0.408, P= 0.009）. Conehlsion The delayed discounting ability is impaired and correlated with the motor impulsiveness in GD patients.
