Escape and avoidance behaviors play a prominent role in the maintenance and possibly development of panic disorder, yet the literature regarding the etiology of these emotion-regulation strategies is relatively underdeveloped. The current study experimentally tests hypotheses that parental modeling of escape during a well-established panic-relevant biological challenge increases panic-relevant escape and avoidance among offspring. Fifty physically and psychologically healthy early adolescents (28 females; Mage=11.58; 86% Caucasian), stratified by gender, were randomly assigned to observe one of their parents (39 females; Mage=40.04): either (a) model completing a 3-min voluntary hyperventilation exercise (no escape modeling group) or (b) model premature termination of a similar procedure (escape modeling group). Offspring in the escape modeling group demonstrated a stronger escape response by discontinuing their own challenge sooner than those in the no-escape modeling group (r=.70). No group differences emerged in terms of avoidance responding, as indexed by nearly identical responding in terms of delay time before initiating the challenge, respiration rate, and self-reported willingness to engage in a second proposed challenge. Results suggest that parental behaviors may play an important role in the development of some forms of panic-relevant responding. These preliminary findings may have important implications for future prevention programs targeting parents and at-risk youth.
逃避和回避行为在惊恐障碍的维持甚至可能发展过程中起着重要作用,然而关于这些情绪调节策略病因的文献相对较少。本研究通过实验检验了以下假设:在一个既定的与惊恐相关的生物学挑战中,父母的逃避行为示范会增加后代与惊恐相关的逃避和回避行为。五十名身心健康的青少年早期个体(28名女性;平均年龄11.58岁;86%为白种人),按性别分层,被随机分配去观察他们的一位父母(39名女性;平均年龄40.04岁):要么(a)示范完成3分钟的自愿过度换气练习(无逃避行为示范组),要么(b)示范提前终止类似程序(逃避行为示范组)。逃避行为示范组的后代比无逃避行为示范组的后代更早中断自己的挑战,表现出更强的逃避反应(r = 0.70)。在回避反应方面没有出现组间差异,这通过在开始挑战前的延迟时间、呼吸频率以及自我报告的参与第二次提议挑战的意愿方面几乎相同的反应来衡量。结果表明,父母行为可能在某些形式的与惊恐相关反应的发展中起重要作用。这些初步发现可能对未来针对父母和高危青少年的预防项目具有重要意义。
