HM 10-7 HM 10-7 contains a measure of global subjective happiness developed by Lyubomirsky and Lepper. They believed that the work on happiness lacked “a global, subjective assessment of whether one of is a happy or unhappy person”.
2
HM 10-7 They began their work with 13 self-report items.
After dropping semantically similar items and items that did not load onto a single factor, their scale was left with only 4 items. Although 4 items seems like a small number, Lyubomirsky and Lepper found the scale to be reliable and valid in tests with 14 samples (including 2 from Russia) with almost 3000 respondents.
3
HM 10-7 Reliability was .86 across the samples; the scale was validated against five measures of happiness and well-being and five dispositional measures that were hypothesized to relate to happiness. Thus, the authors concluded that their scale had excellent psychometric properties.
4
HM 10-7 Based on Lyubomirsky and Lepper’s eight college student standardization samples, you should expect a mean of about 4.86 (mean rating for the four items) and a standard deviation of 1.28. They found no sex or age differences in their samples.
