Abstract: The purpose of this study is to explore the relationship among the level of mindfulness, coping strategies and
quality of life of drug addicts after they returned to society, and to discuss the rationality of carrying out
intervention measures based on mindfulness education. This study recruited 97 drug addicts who had returned
to society in Qujing city, Yunnan Province, China. Participants completed the Five Facet Mindfulness
Questionnaire (FFMQ), the Trait Coping Style Questionnaire (TCSQ) and the Quality of Life Scale for Drug
Addicts (QOL-DA). Collected data were analyzed through SPSS 25.0, the variance test between group,
correlation test and Bootstrap analysis was adopted. The results show that the score of positive coping and
quality of life of drug addicts with high level of mindfulness are higher than those with low level of
mindfulness, and the difference is statistically significant (P<0.05). The mediating effect between positive
coping and quality of life is 0.331, accounting for 72.1% of the total effect. The level of mindfulness mediates
the relationship between coping strategies and quality of life of drug addicts returning to society. The results
indicate that training to improve the level of mindfulness and coping skills should be carried out in certain
communities.
1 INTRODUCTION
The problem of drug abuse has long been seen as a
high priority by the Chinese authorities. Strict laws
on the drug problem have been proved effective in
preventing the spread of drugs within China.
However, these laws unexpectedly hampered the
efforts of drug addicts to return to normal life at the
same time due to the perceived stigma and the social
discrimination. How drug addicts return and integrate
into the society after completing compulsory drug
rehabilitation is a complex social problem and a hot
topic in the field of drug rehabilitation in recent years.
Although there has been a lot of researches
suggesting solutions to the problem of drug
addiction, there has been a lack of research on the
quality of life of drug addicts after they return to
society.
Studies have shown that individuals with drug
addiction history have a significantly lower quality of
life than the general population and are more likely to
relapse into drug use even after they have completely
abandoned drugs (Idrissi, Ahami, Ghaihlan, Azzaoui,
Mammad, 2018). Meanwhile, researches also show
that coping strategies significantly affect individuals'
quality of life (Deng 2009), and individuals with low
quality of life are more likely to perceive depression
and anxiety, and tend to feel more stress in life
(Friedland, Renwick, Mccoll, 1996). Further, an
Iranian study found that individuals who experienced
stressful events were more likely to exhibit opiate use
(Hassan, Askari, Pourmovahed, 2013). In other
words, individuals' inappropriate coping strategies
may lead to relapse behavior.
There is a relationship between individual
mindfulness level and mental health. For example,
relevant studies show that mindfulness level is
negatively correlated with depression, anxiety and
other negative emotions, and positively correlated
with optimism, self-esteem and life satisfaction
(Brown, Ryan 2003). In stressful situations, people
with high mindfulness level used more problem
solving coping strategy and less avoidance coping
strategy.

Based on this, this study proposes the following
hypotheses: The mindfulness level of drug addicts
will affect their coping strategies when facing
stressful events in life, while a positive or negative
coping strategy will further affect the life quality of
them. The main purpose of this study was to
investigate the mediating role of mindfulness level
between coping strategies (positive/negative) of drug
addicts returning to society and their quality of life.
2 METHOD
2.1 Participants
Ninety-seven drug addicts were recruited from
several typical communities in Qujing city, Yunnan
Province, China, with the support of the Qujing
Compulsory Isolation and Drug Treatment Center.
All participants met the following criteria: (1) Within
three years of returning to society after compulsory
isolation; (2) Age range of 18~ 40 years; (3) No
severe mental illness has been diagnosed and no
symptoms of mental illness have been shown.
A total of 112 questionnaires were sent out and 97
valid questionnaires were collected, with an effective
rate of 86. 6%. Among all subjects, 39 were females
with a mean age of 29.5 years (range 19-39 years) and
58 were males with a mean age of 30.4 years (range
22-40 years). The education level of the subjects was
distributed in different education levels: 9 people
(9.3%) had no education or did not complete primary
education, 42 people (43.3%) had and only
completed primary education, 40 people (41.2%) had
and only completed middle school education, and 6
people (6.2%) had completed junior college
education or above. Among the subjects, 33 (34.0%)
were unemployed and 64 (66.0%) were employed.
2.2 Five Facet Mindfulness
Questionnaire, FFMQ
The Five Facet Mindfulness Questionnaire was
compiled by Baer (Baer 2006), and the Chinese
version was revised by Deng Yuqin (Deng 2009),
which was proved to have good reliability and
validity in subsequent studies. The scale was
composed of 39 items, including 5 factors of
observation, description, conscious action, non-
judgment and non-reaction. Participants' level of
mindfulness was measured using 5-level Likert scale,
and the sum of each factor represented the overall
level of mindfulness. In this study, the Cronbach α of
the whole scale was 0.931.
2.3 Trait Coping Style Questionnaire,
TCSQ
Trait Coping Style Questionnaire was compiled by
Kang Gan-jin in 1993 and further revised in 1999
(Jiang, & Zhu 1999). The scale consists of 20 items,
which are divided into positive coping subscales (10
items) and negative coping subscales (10 items). The
scale adopted five Likert scales, from "definitely yes"
to "definitely no", with five scores of 5, 4, 3, 2, and
1. Participants obtained their coping strategy level by
choosing the most suitable coping style. The higher
the score of negative coping, the more likely the
participants were to respond negatively, such as
avoiding problems and suffering. The higher the
positive coping score, the more likely the participants
were to be positive coping, such as taking the
initiative to solve problems. The Cronbach α of the
two subscales are 0.601 and 0.606 respectively.
2.4 Quality of Life Scale for Drug
Addicts, QOL-DA
Quality of Life Scale (QOLS) was first compiled by
American psychologist John Flanagan in the 1970s to
understand the Quality of Life of people with chronic
diseases (Burckhardt, Anderson 2003). After the
questionnaire was compiled, the reliability, content
and structural validity of the questionnaire were
ensured in subsequent studies, and then the
questionnaire was translated into multiple languages
and used in different cultures. Quality of Life Scale
For Drug Addicts were compiled by Wan Chonghua
(Wan 1997). The scale was divided into four
dimensions, namely, physical function, psychological
function, withdrawal symptoms and social function,
with a total of 40 items. The scale was multi-
dimensional, and items were also scored by Likert 5-
level scoring method, that is, 1-5 points were scored
according to 1-5 levels of the answers selected.
Among all items, 8 items are forward items, which
are scored directly, and the rest are backward items,
which need to be converted before scoring. In this
study, the Cronbach α of this scale is 0.821.
2.5 Statistical Methods
All data were analyzed using SPSS 25.0 software.
Demographic variables were analyzed using
descriptive statistics. The t-test was used for

215
comparison between groups. Stepwise regression
was used to investigate the correlation between the
level of mindfulness, coping strategies and quality of
life of drug users. Bootstrap mediating effect analysis
was used to further test whether there were
significant direct or indirect effects among variables.
Statistical test level α=0.05.
3 RESULTS
3.1 Descriptive Statistic
Table 1 lists the minimum, maximum, mean, and
standard deviation of FFMQ, TCSQ, and QOL-DA
scores. The quality of life of drug addicts after they
return tosociety varies widely with a SD of 24.00,
indicating a stark difference in their lives. This result
is consistent with the prediction when the sample was
selected, after completing the compulsory drug
rehabilitation, some drug users soon found jobs and
started a new life, while some subjects could not get
rid of the harm brought by drugs and lived in poverty.
This phenomenon was reflected in the results of all
other questionnaires as well. In FFMQ scale, the
highest score was almost twice the lowest score with
a SD of 16.57. In the TCSQ scale, whether negative
or positive, the highest score was more than twice the
lowest score.

TCSQ(Negative) 14 35 24.73 4.45
QOL-DA 89 162 124.28 16.57
3.2 Significance Test between Groups
According to the percentile of the total score of the
mindfulness level, all the participants were divided
into two groups: the total group of high mindfulness
level, whose FFMQ total score was higher than the
50th percentile; the overall group with low levels of
mindfulness had FFMQ scores below the 50th
percentile. Table 2 shows the mean scores of negative
coping, positive coping, and quality of life between
the two mindfulness groups. The results showed that
the mean value of positive coping in the high
mindfulness group was higher than that in the low
mindfulness group, and the difference was
statistically significant (P<0.05). The mean value of
negative coping in the high mindfulness group was
lower than that in the low mindfulness group, and the
difference was statistically significant (P<0.05). The
quality of life score of the high level of mindfulness
group was higher than that of the low level of
mindfulness group, and the difference was
statistically significant (P<0.001)

3.3 Correlation Analysis
The correlation between mindfulness level, positive
and negative coping strategies and quality of life of
drug addicts was tested. The four factors are all
significantly correlated at the 0.01 level, while
mindfulness level was positively correlated with
positive coping and quality of life with a regression
coefficient of 0.42 and 0.68 respectively, and
negatively correlated with negative coping with the
regression coefficient of -0.46. Subsequently, the
positive coping was positively correlated with quality
of life with the regression coefficient of 0.37, while
the negative coping was negatively correlated with
both positive coping and quality of life with the
regression coefficient of -0.3 and-0.39 respectively.

3.4 Mediating Effect Analysis
Stepwise regression and Bootstrap methods were
used to test the mediating effect of the level of
mindfulness, taking the quality of life of drug addicts
as the dependent variable, positive and negative
coping as the independent variable, and the level of
mindfulness as the mediating variable. The results
indicate that the prediction of coping strategies over
quality of life is not significant when the mindfulness
level was introduced, which evidences the full
mediation between them. The results were shown in
table 4. A model of the mediating effect model of
mindfulness level was subsequently established,
indicating that percentage of indirect effects was
72.1%.

4 DISCUSSION
This study explored the relationship between the
level of mindfulness, coping style and quality of life
of drug users after completing compulsory drug
withdrawal and returning to society, and proposed
new findings. Participants recruited for this study had
a history of substance abuse and addiction and had a
significantly lower quality of life than non-drug
exposed groups (Li & Wu 1995). These results
indicate that although drug users have returned to
society, the quality of life is not good. The quality of
life of drug users is lower than that of the general
population in terms of physical, psychological and
social relations (Wan, Fang & Liying 2000). These
are consistent with our findings.
As expected, levels of mindfulness significantly
mediated the relationship between positive coping
and quality of life in this study. Drug addicts with
more positive coping styles had higher levels of
mindfulness and better quality of life. Compared with
the general population, drug users used more
avoidant coping and less active behavioral coping
(Ma, Yang, & Yang 2017). For drug users, more
stressful life events, greater mental stress, and
inappropriate and ineffective coping strategies may
play an important role in their addiction and relapse
(Kruse 2011).
Therefore, if drug addicts lack appropriate
guidance and adequate social and family support,
they are easily frustrated by stressful events in life.
Under the combined effect of low level of
mindfulness and negative coping style, it is difficult
for them to successfully integrate into society, thus
reducing their quality of life. At the same time, low
quality of life leads to more stressful events, and more
stressful events lead to more difficulties in improving
quality of life, creating a vicious cycle that is difficult
to break out of. This corollary provides an
explanation to the problem pointed out by Gorelick
in 1993 that relapse is widespread among drug users,
even they have succeeded in compulsory drug
withdrawal (Gorelick 1993).
In communities with serious drug abuse
problems, mindfulness education should be widely
carried out for drug addicts returning to society. High
levels of mindfulness help them adopt positive
coping strategies in the face of various stresses and
further improve their quality of life. At the same time,
special institutions should be established to train drug
users in coping flexibility. Active coping strategies
can also significantly improve the quality of life of
individuals. In addition, attention should be paid to
the demographic characteristics of drug addicts
returning to society and appropriate interventions
should be carried out to prevent relapse. For example,
studies have shown that specific interventions and
treatments have significantly different effects on drug
users of different genders (Nelson, Kauffman & Dore
1995), and strict implementation of a single
intervention will not produce the expected results.
5 CONCLUSION
This study investigated the relationship between the
level of mindfulness, coping strategies and quality of
life of drug addicts after returning to society. The
level of mindfulness is positively correlated with both
positive coping and quality of life, and negatively
correlated with negative coping, which further
negatively predicted the quality of life. Individuals
with high levels of mindfulness scored significantly
higher on positive coping and quality of life than
individuals with low levels of mindfulness. The level
of mindfulness significantly mediated the
relationship between positive coping and quality of
life. Understanding the relationship between levels of
mindfulness, coping style and quality of life is of
great significance to help drug addicts successfully
return to society, prevent potential relapse risk, and
improve their quality of life.
There are limitations to this study. Because of the
widespread problem of relapse, the number of drug
users who successfully return to society is very rare,
regardless of their living conditions. A total of 112
subjects were recruited in this study, 97 of whom
gave valid questionnaire results. This number is not
enough to establish a sufficient structural equation
model of good model fit. In addition, the cross-
sectional non-longitudinal design of this study makes
it difficult to fully explain how the level of
mindfulness of drug users is formed, and the practical
effect of mindfulness-based intervention on
improving the quality of life of drug users is unclear.
Follow-up studies can expand the number of
participants worldwide and proceed further in this
direction.
