焦虑情绪对海洛因依赖者注意定向的影响

目的研究海洛因依赖者特质焦虑与状态焦虑对其注意定向过程的影响。方法通过状态焦虑量表以及特质焦虑量表评估40例海洛因依赖者(男36例,女4例)和40名对照者(男36名,女4名)的状态焦虑和特质焦虑,并采用线索—目标范式评估被试者注意定向中的直接定向与解离/重新定向过程。结果海洛因依赖组的状态焦虑(42.65±6.58)vs.(36.60±8.91)]和特质焦虑(44.43±7.67)vs.(37.00±8.63)]评分高于对照组,差异有统计学意义(P0.05)。相关分析示,海洛因依赖者的状态焦虑(r=-0.259,P=0.020)、特质焦虑(r=-0.248,P=0.026)分别与直接定向反应时差值呈负相关,并与解离/重新定向反应时差值呈正相关状态焦虑(r=0.333,P=0.003);特质焦虑(r=0.356,P=0.001)]。结论海洛因依赖者具有较严重的焦虑情绪,状态/特质焦虑可能与海洛因依赖者的直接定向过程以及解离/重新定向过程有关。

The effect of anxiety on attentional orienting of heroin addicts

Objective To investigate the effect of state anxiety and trait anxiety on attentional orienting of heroin addicts. Methods State anxiety and trait anxiety was measured by State-Trait Anxiety Inventory (STAI). Forty heroin ad?dicts (36 males and 4 females) and 40 healthy controls (36 males and 4 females) participated in cue-target task. Atten?tional orienting and reorienting were measured in valid cue trials and invalid cue trails. Results Heroin addicts had sig?nificantly greater state anxiety (42.65 ± 6.58) vs. (36.60 ± 8.91)] and trait anxiety (44.43 ± 7.67) vs. (37.00 ± 8.63)] values than controls (P<0.05). The state anxiety was significantly correlated with orientation RT difference (r=-0.259, P=0.020) and disengaging/reorientation RT difference (r=0.333, P=0.003) in heroin addicts. Trait anxiety was also significantly cor?related with orientation RT difference (r=-0.248, P=0.026) and disengaging/reorientation RT difference (r=0.356, P=0.001) in heroin addicts. Conclusion Heroin addicts have significantly greater anxiety than healthy controls. Both their state anxiety and trait anxiety are associated with attentional orienting and disengaging/reorienting.
