Abstract：
The significance of physiological regulation in relation to behavioral and emotional regulation is well documented, but primarily in economically advantaged contexts. Few studies have been conducted in low- and middle-income countries. We investigated the feasibility and reliability of measuring autonomic nervous system (ANS) activity and behavior during challenge tasks in 30 children aged 8-10 years in Ghana during two visits, 1 week apart. Completeness of ANS data ranged from 80% to 100% across all tasks. There was low-to-moderate test-retest reliability of video mood induction (VMI) emotion ratings and balloon analog risk task (BART) pumps (r = 0.34-0.52). VMI elicited higher targeted emotion ratings in Visit 2 than Visit 1. Respiratory sinus arrhythmia (RSA) was higher, and pre-ejection period (PEP) was longer at Visit 2 than Visit 1 for baseline and both tasks. RSA was higher at baseline than during the VMI anger scene at Visit 1, whereas PEP was shorter at baseline than during all VMI emotion scenes at Visit 2. RSA was higher at baseline than during BART at both visits. In conclusion, ANS data collection within evocative and arousing challenge tasks was feasible in Ghana, and the tasks were generally reliable and effective in eliciting target emotions and risk-taking behavior in this sample.
摘要：
生理调节与行为和情绪调节有关的重要性有据可查，但主要是在经济有利的环境中。在低收入和中等收入国家进行的研究很少。我们在两次访问中调查了加纳30名8-10岁儿童在挑战任务中测量自主神经系统（ANS）活动和行为的可行性和可靠性，相隔一周。在所有任务中，ANS数据的完整性从80%到100%不等。视频情绪感应（VMI）情绪评分和气球模拟风险任务（BART）泵具有低到中等的重测可靠性（r=0.34-0.52）。VMI在第2次访问中引起比第1次访问更高的针对性情绪评级。呼吸性窦性心律失常（RSA）较高，对于基线和两项任务，第2次访问的射血前期（PEP）比第1次长。RSA在基线时比在第1次访问的VMI愤怒场景期间高，而PEP在基线时比在第2次访问的所有VMI情绪场景期间短。在两次访问中，RSA在基线时均高于BART期间。总之,在加纳，在唤起和唤起挑战任务中收集ANS数据是可行的，在此样本中，任务通常可靠且有效地引发目标情绪和冒险行为。
