Researchers have begun in recent times to distinguish two aspects of personal well-being: Emotional well-being, in which respondents are asked about the quality of their everyday emotional experiences — the frequency and intensity of their experiences of, for example, joy, stress, sadness, anger, and affection — and life evaluation, in which respondents are asked to think about their life in general and evaluate it against a scale.
