Abstract

Watching news broadcasts is known to elicit psychological stress. Conversely, the iconic painter Bob Ross (BR) has risen to pop culture status and amassed a following, as many find the messages and sounds of BR to be soothing and relaxing. Though, it has yet to be directly tested if such exposure can confer psychological or physiological benefit. The purpose of this study was to compare the effects of watching BR versus streaming news on markers of cardiovascular health and profile of mood states (POMS). It was hypothesized that watching BR would increase POMS scores and heart rate variability (HRV). It was also hypothesized that watching the news would increase blood pressure (BP), vascular stiffness (VS), and heart rate (HR).

Methods

In a randomized, controlled, crossover design, 18 young (21 ± 1 yrs, 9 female, 9 male) healthy participants (172.6 ± 9.9 cm, 69 ± 18 kg) were assessed for BP, VS, HR, HRV, and POMS before and after watching an episode of BR or the News matched for time (∼27 mins). Results: A significant interaction effect on POMS scores were observed for, anxiety (p = 0.01), anger (p = 0.008), depression (p = 0.003), fatigue (p = 0.001), and confusion (p = 0.01) domains after watching BR. The LF/HF ratio, an HRV marker of sympathovagal balance, was significantly lower after watching BR (p = 0.04). There were no significant time, condition, or interaction effects on systolic BP, mean arterial pressure, and diastolic BP.

Conclusion

The “Bob Ross Effect” reduces overall mood disturbance, though appears to exert little influence on the cardiovascular system in this acute paradigm.

探索鲍勃-罗斯效应：心理生理学调查

众所周知，观看新闻广播会引起心理压力。与此相反，标志性画家鲍勃-罗斯（Bob Ross）却在流行文化中崭露头角，赢得了众多追随者，因为许多人认为鲍勃-罗斯的信息和声音能让人舒缓和放松。不过，这种接触是否会带来心理或生理上的益处还有待直接测试。本研究的目的是比较观看广播和流媒体新闻对心血管健康指标和情绪状态（POMS）的影响。研究假设，观看广播会提高 POMS 分数和心率变异性（HRV）。方法在随机对照交叉设计中，18 名年轻（21±1 岁，9 名女性，9 名男性）健康参与者（172.6±9.9 厘米，69±18 千克）在观看一集广播节目或新闻节目（约 27 分钟）前后接受了血压、血管僵硬度、心率、心率变异性和 POMS 评估。结果显示在观看 BR 后，焦虑（p=0.01）、愤怒（p=0.008）、抑郁（p=0.003）、疲劳（p=0.001）和困惑（p=0.01）域的 POMS 分数出现了明显的交互效应。作为交感-迷走平衡的心率变异标志的 LF/HF 比值在观看 BR 后显著降低（p=0.04）。结论 "鲍勃-罗斯效应 "可减少整体情绪紊乱，但在这种急性范例中似乎对心血管系统影响甚微。
