Forty-eight females were evaluated to detect differences in panic-related symptomatology and physiological responses to 2 min of hyperventilation. Ss were divided into 3 groups: infrequent panickers; no panic/high trait anxiety; and no panic/low trait anxiety. The low trait anxiety group scored significantly lower on various self-report measures of anxiety-related symptomatology compared to Ss with infrequent panic and high trait anxiety. Hyperventilation produced no significant group differences in physiological reactivity or recovery. However, Ss with low trait anxiety reported significantly less severe sensations and a significantly lower incidence of panic during hyperventilation than the infrequent panickers and the high trait anxiety group. Ss who panicked during hyperventilation reported more intense sensations and negative cognitions than those who did not panic. Thus, Ss were distinguished by their subjective, but not their physiological responses.
对48名女性进行了评估,以检测与惊恐相关的症状学以及对2分钟过度换气的生理反应方面的差异。受试者被分为3组:不常惊恐者;无惊恐/高特质焦虑者;无惊恐/低特质焦虑者。与不常惊恐且高特质焦虑的受试者相比,低特质焦虑组在各种与焦虑相关症状学的自我报告测量中得分显著更低。过度换气在生理反应性或恢复方面未产生显著的组间差异。然而,低特质焦虑的受试者在过度换气期间报告的感觉严重程度显著更低,惊恐发生率也显著低于不常惊恐者和高特质焦虑组。在过度换气期间惊恐的受试者比未惊恐的受试者报告有更强烈的感觉和消极认知。因此,受试者的区别在于其主观反应,而非生理反应。
