Summary
This summary is machine-generated.

Visual analogue scales (VAS) reliably measure subjective energy levels, correlating with vigour, fatigue, and positive emotions. These energy perceptions show distinct daily patterns, influenced by personality traits like extraversion and neuroticism.

Area of Science:

  • Psychology
  • Psychophysiology
  • Well-being Research

Background:

  • Subjective energy levels are crucial indicators of overall well-being.
  • Understanding the diurnal variation and correlates of mental and physical energy is important for health research.

Purpose of the Study:

  • To assess the reliability of visual analogue scales (VAS) in measuring subjective mental and physical energy.
  • To explore the correlations between energy levels, vigour, fatigue, affect, and personality traits.
  • To investigate the diurnal patterns of these variables.

Main Methods:

  • Normal volunteers recorded subjective perceptions of mental and physical energy using VAS daily for one week.
  • Standard adjectival formats assessed vigour and fatigue.
  • Measures of positive affect, negative affect, extraversion, neuroticism, and happiness were utilized.

Main Results:

  • VAS-derived energy ratings strongly correlated with vigour, fatigue, and positive affect.
  • Physical and mental energy, vigour, and positive affect peaked in the morning and declined throughout the day; fatigue showed an inverse pattern.
  • Extraversion correlated positively with energy and affect, while neuroticism correlated negatively, and vice versa for fatigue and negative affect.

Conclusions:

  • VAS ratings provide reliable and stable measures of self-perceived vigour and fatigue.
  • Subjective energy levels exhibit predictable diurnal variations.
  • Personality traits significantly influence perceived energy, affect, and fatigue, suggesting their utility in broader well-being and physiological studies.
