To examine the effects of a brief psychosocial manipulation on physiological responses to laboratory stress in lower and higher socioeconomic status (SES) adolescents.
A total of 115 adolescents participated in two acute laboratory stress tasks: one with psychosocial intervention and one with no intervention. In the intervention condition, half of the adolescents were given control over the stressor parameters; the other half received social informational resources (hints provided by another person) for dealing with the stressor. Physiological reactivity was monitored.
Lower SES adolescents exhibited less physiological reactivity when provided with intervention compared with no intervention. Within the lower SES group, the resource condition reduced physiological reactivity more than the control condition did. Higher SES adolescents did not respond physiologically to intervention.
This study provides a preliminary illustration of an experimental laboratory approach to studying SES-health relationships and suggests that providing informational support during a stressor may have beneficial implications for the physiological health of lower SES adolescents.
研究一种简短的心理社会干预对社会经济地位较低和较高的青少年在实验室应激状态下生理反应的影响。
共有115名青少年参与了两项急性实验室应激任务：一项有心理社会干预，另一项无干预。在干预条件下，一半青少年可控制应激源参数；另一半则获得社会信息资源（他人提供的提示）以应对应激源。监测生理反应性。
与无干预相比，社会经济地位较低的青少年在接受干预时生理反应性较低。在社会经济地位较低的组中，资源条件比控制条件更能降低生理反应性。社会经济地位较高的青少年对干预没有生理反应。
本研究为研究社会经济地位与健康关系的实验性实验室方法提供了初步例证，并表明在应激源出现时提供信息支持可能对社会经济地位较低的青少年的生理健康有有益影响。
