USE OF GUIDED IMAGINATION IN ANXIETY TREATMENT IN ADULT PATIENTS IN THE PSYCHOLOGICAL CLINIC
Anxiety, Systematic Review; Intervention, Guided Imagery
Anxiety is the body's natural response to situations perceived as challenging, dangerous or
stressful. When it exceeds normal limits and becomes persistent, this response can evolve to a pathological
level. An anxiety disorder is a complex and multifaceted phenomenon, being an object of interest in
several areas, including psychology, neuroscience and psychiatry. This dissertation includes two studies,
presented in article format, one being a review and the second an empirical research, with a quasi-
experimental design. The first article aimed to identify evidence that the use of guided imagery, as a non-
pharmacological intervention, contributes to reducing anxiety levels in adults. A systematic review was
carried out, guided by PRISMA parameters, searching for peer-reviewed articles, published between 2018
and 2022, in the SciELO, SCOPUS and PsycINFO databases. 740 studies were found and, after screening
and applying eligibility and exclusion criteria, 12 articles were selected. Regarding the design, eight
studies were randomized controlled and four did not apply the randomization criteria. The 12 studies
indicated a statistically significant reduction in participants' anxiety levels after intervention using guided
imagery. The studies indicated that the technique can be used in different contexts, with varied
populations and comorbidities, being favorable as a complementary non-pharmacological technique. It is
concluded that intervention with guided imagination, whether in a hospital or non-hospital context,
constitutes an efficient way of reducing anxiety levels, according to the results of the studies in this
systematic review. The second article aimed to evaluate the effects of guided imagery intervention on the
perceived level of anxiety in adults, in the psychological clinic, with a quasi-experimental design. Four
adults participated and underwent eight weekly guided imagination sessions. Three comparison measures
were carried out (pre-test, post-test and follow-up after one month), using the Beck Anxiety Inventory
(BAI), the anxiety subscale of the Hospital Anxiety and Depression Scale (HADS-A) and the Mini
International Neuropsychiatric Interview - MINI. Participants' reports were recorded throughout the
sessions and at follow-up, and categorized. Based on non-parametric analysis (Friedman's ANOVA), the
results showed that the mean HADS-A rank scores in the pre-test were significantly higher than in the
post-test (p=0.024). The value rose a little in the follow-up, but still remained lower than in the pre-test,
however the difference was not statistically significant. There was no statistically significant difference in the BAI, although the average ranks reduced in the post-test and follow-up. Analyzing the cases individually, the results indicated that the participants benefited, in varying ways, from the guided imagination technique, with two of them benefiting differently. Diverging from the research analyzed in the systematic review, the intervention study was carried out in the context of the psychological clinic, with limitations regarding the number of participants, absence of a control group and follow-up time. It is concluded that the technique contributed to reducing anxiety, proving to be an additional treatment resource in cases of disorder.
