showed that gratitude intervention is the most
effective intervention to reduce stress, meanwhile,
mindfulness interventions are the most effective for
reducing depression and increase happiness. Previous
studies also supported that gratitude was related to
increasing the welfare of individuals and reducing
symptoms of depression, including research
conducted by Martinez-Marti, Avia, and Hernandez-
Lloreda in 2010 indicating that gratitude
interventions had an impact on wellbeing.
2 LITERATURE REVIEW
2.1 Stress
The term stress was first introduced in health
psychology by Hans Selye in 1926, which is the non-
specific response of the body to any demands on its
burden (Baqutayan, 2015). The emergence of stress is
also influenced by the individual's assessment of a
situation or event, as stated by Lazarus and Folkman
(1984) which defines stress as a relationship between
individuals and the environment that is judged by
someone as a demand or inability to face-threatening
or dangerous situations. The concept of stress is
known as the transactional model, namely, stress is
considered as the interaction between individuals and
their environment (Lazarus & Folkman, 1984). The
transactional meaning of stress also emphasizes
subjective judgment, so that the same stimulus can
produce different interpretations, responses, and
coping strategies among individuals with different
experiences and personality traits (Ng, 2013).
In accordance with the stress theory of the
transactional model presented by Lazarus, then
Cohen and Williamson (1988) developed a measuring
device Perceived Stress Scale (PSS-10) that measures
the extent to which an event is valued as stressed by
someone. The original scale of the Perceived Stress
Scale was developed in 1983 by Cohen, Kamarck,
and Mermelstein with reference to the perspective of
Lazarus theory(1966, 1977) which states that stress is
determined by one's perception of their stress. The
development of the PSS scale is also due to the fact
that the theoretical perspective on stress perception
was not accompanied by the development of valid
measurement tools to measure perceived stress
(Cohen, Kamarck, & Mermelstein, 1983).
Perceived stress is an individual's assessment of
an event that is considered as stress (Cohen et al.,
1983). Perceived stress includes individual feelings
about things that cannot be controlled and predicted
in a person's life, how often someone is exposed to
difficulties, changes that occur in life, and beliefs in
the ability to deal with problems (Cohen et al., 1983).
Lazarus (in Cohen, et al., 1983) revealed that a
person's stress level is determined by one's perception
of stress. The general situation in life is considered as
stressful when unpredictable, uncontrollable, or
overloading. The perceived stress reflects stress
levels experienced as a function of objective stressful
events, coping processes and personality factors
(Cohen et al., 1983).
2.2 Gratitude
According to the American Heritage Dictionary of the
English Language, the origin of the word gratitude is
from Latin, namely gratus or gratitude which means
thankfulness or praise (pleasing), whereas in
Indonesian thank you can be combined with gratitude
(Listiyandini, Nathania, Syahniar, Sonia, & Nadya,
2015). McCullough, et al., (2002) define gratitude as
one of the psychological conditions as an emotion,
attitude, moral virtue, personality trait, or a way of
responding that can contribute to mental health.
Furthermore, according to Watkins, Woodward,
Stone, and Kolts (2003) gratitude is a feeling that
encourages to thank and appreciate the pleasure that
has been received, giving rise to calm,
psychologically satisfied conditions.
The concept of gratitude that is formed in
individuals cannot be separated from the learning
process that leads to one value, very closely related to
the cultural, religious and philosophical values that
surround it (Haryanto & Kertamuda, 2016).
Listiyandini, et al., (2015) define gratitude as a
feeling of gratitude, happiness, and appreciation for
things that have been gained during life, both from
God, humans, other creatures, and the universe,
which then encourages someone to do the same as
obtained. Then Listiyandini, et al. (2015) suggested
that several scales developed in the West to measure
gratitude generally did not explicitly mention aspects
of divinity. Some of these measures raise the
spirituality of gratitude without involving the terms
and roles of God in them and prioritizing terms such
as the role of nature, the world, and others 'strengths'
outside of humans. The same thing was stated by
Haryanto and Kertamuda (2016) that a fairly basic
difference regarding the concept of gratitude in
western literature in the form of an emphasis on the
existence of God as an important party in
understanding gratitude.
This research refers to the definition of gratitude
which is explained by this because the definition is
quite representative in describing gratitude to
