Subjective perceptions of mental and physical energy were measured by the use of visual analogue scales (VAS) over the course of a week in a group of normal volunteers. These variables were found to correlate, highly both with one another and with assessments of vigour and fatigue measured with a standard adjectival format. In addition, high correlations were found with a measure of positive affect. These five variables also displayed characteristic patterns of diurnal variation. Physical and mental energy, vigour and positive affect were highest in the morning, falling progressively and significantly over the day. In contrast, fatigue showed the opposite pattern. Extraversion showed positive correlations with physical and mental energy, vigour and positive affect, and negative correlations with fatigue and negative affect, most being significant (P less than 0.05). Conversely, neuroticism showed a negative correlation with the first four energy variables but was positively related to fatigue and negative affect, most correlations again being significant. Physical and mental energy, vigour and positive affect also showed a positive correlation (P less than 0.01) with a measure of happiness. It is concluded that VAS-derived ratings of physical and mental energy are reliable indicators of self-perceived vigour and fatigue. They are easy to record and show sufficient short-term stability to be used in more extensive studies both of well-being and of its physiological correlates.
在一组正常志愿者中，通过使用视觉模拟量表（VAS）在一周的时间内测量了心理和身体能量的主观感受。发现这些变量之间以及与用标准形容词格式测量的活力和疲劳评估之间都高度相关。此外，还发现与积极情绪测量指标有高度相关性。这五个变量还呈现出昼夜变化的特征模式。身体和心理能量、活力以及积极情绪在早晨最高，在一天中逐渐显著下降。相比之下，疲劳呈现相反的模式。外向性与身体和心理能量、活力以及积极情绪呈正相关，与疲劳和消极情绪呈负相关，大多数相关性显著（P小于0.05）。相反，神经质与前四个能量变量呈负相关，但与疲劳和消极情绪呈正相关，大多数相关性再次显著。身体和心理能量、活力以及积极情绪与幸福感测量指标也呈正相关（P小于0.01）。得出的结论是，由VAS得出的身体和心理能量评分是自我感知活力和疲劳的可靠指标。它们易于记录，并且显示出足够的短期稳定性，可用于更广泛的关于幸福感及其生理相关性的研究。
