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”.




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.



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.



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.
