Abrahams, & Sinclair, 2017). With the high level of
trust in CBT, the effectiveness of the intervention is
certainly no doubt.
Other studies have suggested that to provide
effective results in improving psychological well-
being, interventions with narrative or behavioral
approaches appear promising (Ruini, Masoni,
Otolini, & Ferrari, 2014; Weiss, Westerhof, &
Bohlmeijer, 2016). Through this trial of the
Evidence-Based Community Counseling model, it
was found that the cognitive-behavioral approach
also had a significant impact on improving
psychological well-being, especially for ex-drug
addicts. These results certainly provide support for
similar studies that use cognitive-behavioral
approaches to improve psychological well-being
(Yazdanbakhsh, Merzai, Dehghan, & Mahmoudi,
2016).
However, methodologically the number of
samples used in the prototype model trial can be said
to be too small. Limitations of time and resources
make testing done limited in one community. In
addition hypothesis testing is carried out using non-
parametric statistical methods which do not require
the assumption of normal distribution. This makes
the test results obtained despite being proven to be
empirically effective, still cannot be generalized to a
wider population. Therefore, it is necessary to have
more samples to be able to generalize the findings.
Furthermore, confidence in the treatment effects
that appear in the results of the trial of this model
may not escape bias, given that some internal
validity is poorly maintained. Internal validity refers
to how reliable the effect of a treatment is to
influence a variable (Creswell, 2015). Some things
like implementation that are not standardized
between each session, the implementation of one or
two sessions that are interrupted by the community
authority, and the duration of several sessions that
are not adhered to may cause bias in the test results.
It is important for future researchers to be able to
control this internal validity before testing the model
to get a more optimal measurement result.
4 CONCLUSIONS
In the end, the findings of this study stated that the
evidence-based community counseling was a better
model for improving psychological well-being in
individual ex-drug addicts compared to general
treatment. As evidenced by the comparison with
treatment as usual, psychological well-being in
experimental subjects experienced a significant
increase in measurements after treatment. Thus, the
evidence-based community counseling might be
considered as an alternative for efforts to help ex-
drug addicts to improve their psychological well-
being.
However, these results contain several biases
such as too few samples, controls on less stringent
treatment, and various other internal validity
problems. In addition, some things have not been
clearly ascertained in this research, as it is still
unknown whether positive changes in the score of
psychological well-being can last longer or are only
temporary, and whether whether psychological well-
being increases really correlates with the longer
period of abstinence an ex-drug addict. Therefore,
further research is needed to ensure this, of course
with more rigorous research methods.
