Measuring happiness is an important issue for many disciplines. Many researchers have measured happiness with a questionnaire method. Some important scales in the literature are: Single-Item Measurement of Happiness (Abdel-Khalek, 2004); Subjective Happiness Scale (Lyubomirsky and Lepper, 1999); Satisfaction with Life Scale (SWLS) (Diener et al., 1985); Oxford Happiness Questionnaire (Hills and Argyle, 2002); and Bhutan's Gross National Happiness Index (Ura et al., 2012). Happiness measurement is done by asking people how happy they are. Two main approaches are used. Experience sampling (Larson & Csikszentmihalyi, 2011) and day reconstruction (day reconstruction) (Kahneman et al., 2004). You can ask yourself if you are happy or not and give a ratio between “1 (very unhappy) to 9 (very happy)”. The result will give you an idea about your subjective happiness. You can use Oxford Happiness Questionnaire (Hills and Argyle, 2002) or authentic happiness questionnaires (https://www.authentichappiness.sas.upenn.edu/ ) to measure your subjective happiness.
