Assessing Quality of Answers to a Global Subjective Well-being Question Through Response Times.

Many large-scale surveys measure subjective well-being (SWB) through a single survey item. This paper takes advantages of response time data to explore the relation between time taken to answer a single SWB item and the reliability and validity of answers to this SWB item. We found that reliability and validity of answers to the SWB item are low for fast respondents aged 70 and above and slow respondents between the age of 50 and 70.
