Few laboratory paradigms exist that expose adolescents to conflict that might commonly be experienced in parent-adolescent relationships. Given the continued importance of parent-adolescent relationships on adolescent development, as well as the changing expectations in these relationships, we examined the effect of a novel parent-adolescent conflict paradigm on physiological and affective response in a sample of 52 adolescents. The parent-adolescent conflict stressor (PACS) involved adolescent participants (50% girls; M = 14.75, SD = 0.88) watching a 12-minute scripted video that asked youth to imagine that they were the teenager in the video, which consisted of parent and adolescent actors having discussions about conflict in their relationship and solving this conflict in either a positive, typical, or hostile manner. Cortisol, alpha amylase, and self-report of negative and positive affect were collected at baseline, following the video, and during a recovery period. Heart rate also was taken continuously while adolescents watched the videos. Hierarchical linear modeling (HLM) analyses indicated significant linear change in alpha amylase and linear and quadratic change in negative affect to the PACS. There also was a significant linear and quadratic change in heart rate during the portion of the video where teens and parents discussed issues of personal responsibility. The PACS marks a preliminary but important first step in developing a parent-adolescent conflict paradigm that can be used across studies to understand the impact of parent-adolescent conflict on affective and physiological markers associated with stress response.
很少有实验室范式能让青少年面临亲子关系中可能普遍经历的冲突。鉴于亲子关系对青少年发展持续具有重要意义，以及这些关系中不断变化的期望，我们在52名青少年样本中研究了一种新型亲子冲突范式对生理和情感反应的影响。亲子冲突应激源（PACS）包括青少年参与者（50%为女孩；M = 14.75，SD = 0.88）观看一段12分钟的脚本视频，要求青少年想象自己是视频中的青少年，视频内容是父母和青少年演员讨论他们关系中的冲突，并以积极、典型或敌对的方式解决冲突。在基线期、视频观看后以及恢复期收集皮质醇、α淀粉酶以及负面和正面情绪的自我报告。青少年观看视频时还持续测量心率。分层线性模型（HLM）分析表明，α淀粉酶有显著的线性变化，负面情绪对PACS有线性和二次变化。在青少年和父母讨论个人责任问题的视频部分，心率也有显著的线性和二次变化。PACS标志着开发一种亲子冲突范式的初步但重要的第一步，该范式可用于跨研究，以了解亲子冲突对与应激反应相关的情感和生理指标的影响。
