Effectiveness of trauma-focused treatment for adolescents with major depressive disorder

Stressful life events, post-traumatic stress disorder symptoms and mental health in individuals with intellectual disabilities: a scoping review

BACKGROUND

Stressful life events are events that do not fulfil the A criterion of PTSD in the DSM-5(TR) but are perceived as negative by the person. There is an ongoing debate about the usefulness of the A criterion as a gate criterion for PTSD, and especially regarding which events qualify as traumatic or stressful life events. This debate is particularly important for individuals with intellectual disabilities (ID) or borderline intellectual functioning (BIF), as they seem to be more likely to experience traumatic and stressful life events than their peers without ID-BIF and appear to be more susceptible to the disruptive effects of these events. As a result, people with ID-BIF are more likely to develop mental health and behavioural problems. There is insufficient knowledge about how the relationship between stressful life events and PTSD symptoms should be interpreted, how traumatic and stressful life events are defined and distinguished in people with ID, and whether the A criterion should be broadened for individuals with ID-BIF. The aim of this scoping review was to understand stressful life events and their relationship with PTSD symptoms, other mental health and/or behavioural problems in individuals with ID-BIF.

METHODS

The scoping review was conducted in accordance with the JBI methodology for scoping reviews and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR).

RESULTS

Thirty-eight studies were included. Five studies focused on stressful life events and PTSD symptoms. The other studies examined associations between stressful life events and other mental health and/or behavioural problems. Most of the studies did not clearly differentiate between stressful and traumatic events according to the A criterion of PTSD in the DSM-IV (TR) or DSM-5(TR). Of the six studies in which stressful life events were specified and could be distinguished from traumatic events, one found a positive association between PTSD symptoms and stressful life events and five showed weak to strong positive associations with other mental health and/or behavioural problems.

CONCLUSIONS

PTSD symptoms following stressful life events in individuals with ID-BIF are underrepresented in the literature. The lack of a clear definition of stressful life events leads to a gap in the knowledge on whether and how stressful life events may lead to PTSD symptoms, other mental health and/or behavioural problems in individuals with ID-BIF. Therefore, no general conclusions or recommendations can be made regarding the appropriateness of the PTSD A criterion for individuals with ID-BIF. Further research is needed to establish the role of stressful life events in relation to PTSD symptoms and to inform the assessment and effective treatment in people with ID-BIF, as expert clinical experience studies suggest that broadening the PTSD A criterion should be considered for people with ID-BIF.

EMDR Flash Technique in adolescents with depression: A twelve-week follow-up study

This study aims to investigate the specific effects of the EMDR Flash Technique on adolescents with depression. This follow-up study consists of 32 adolescents, 12-17 years of age (M = 14.34, SD = 1.56), including 7 males and 25 females. They were evaluated with Kiddie Schedule for Affective Disorders and Schizophrenia for School-Age Children Present, the Beck Depression Inventory (BDI), and Children Revised Impact of Event Scale-8 (Crıes-8). These were administered at baseline, at the end of the 4th and 12th weeks of treatment. The EMDR Flash Technique which can be utilized in the preparation phase of Eye Movement Desensitization and Reprocessing (EMDR) to reduce the intensity of highly distressing memories rapidly and relatively painlessly was applied for 12 weeks, one session per week as a free-standing intervention. Also, the EMDR Flash Technique can be effective in decreasing the rate of noncompliance and drop-outs of adolescents. The baseline means of total BDI scores decreased from 48.19 to 2.16 at the end of the 12th week of treatment. Also, the CRIES scores decreased from 31.78 to 0.44 at the end of the 12th week of treatment. In addition, the baseline means of SUD scores decreased from 9.53 to zero at the end of the 12th week of treatment. Overall, our results underscore the effectiveness of the EMDR-Flash Technique in adolescents with depression.

Eye movement desensitization and processing for adolescents with major depressive disorder: study protocol for a multi-site randomized controlled trial

BACKGROUND

Major depressive disorder (MDD) is one of the most common mental disorders in adolescence carrying a serious risk of adverse development later in life. Extant treatments are limited in effectiveness and have high drop-out and relapse rates. A body of literature has been published on the association between distressing/ traumatic experiences and development and maintenance of MDD, but the effectiveness of a trauma-focused treatment approach for MDD has hardly been studied. This study aims to determine the effectiveness of eye movement desensitization and reprocessing (EMDR) therapy as stand-alone intervention in adolescents diagnosed with MDD.

METHODS

This study will be a randomized controlled trial with two conditions: (1) EMDR treatment (6 sessions) and (2) waiting list condition (WL: 6 weeks, followed by EMDR treatment). First, participants receive a baseline measure after which they will be randomized. Participants will be assessed post-intervention after which the WL participants will also receive six EMDR sessions. Follow-up assessments will be conducted at 3 and 6 months follow-up.

STUDY POPULATION

In total, 64 adolescents (aged 12-18) diagnosed with a major depressive disorder (DSM-5) and identified memories of at least one distressing or traumatic event related to the depressive symptomatology will be included. Main study parameters/endpoints: Primary outcome variables will be the percentage of patients meeting criteria for MDD classification, and level of depressive symptoms. Secondary outcome measures include symptoms of PTSD, anxiety, and general social-emotional problems. At baseline, family functioning and having experienced emotional abuse or neglect will be assessed to explore whether these factors predict post-treatment outcome.

DISCUSSION

With the present study, we aim to investigate whether EMDR as a trauma-focussed brief intervention may be effective for adolescents with a primary diagnosis of MDD. EMDR has been proven an effective treatment for traumatic memories in other disorders. It is hypothesized that traumatic memories play a role in the onset and maintenance of depressive disorders. Particularly in adolescence, early treatment of these traumatic memories is warranted to prevent a more chronic or recurrent course of the disorder.

Eye movement desensitization and reprocessing for depression: a systematic review and meta-analysis

Background: In recent years, eye movement desensitization and reprocessing (EMDR) has been applied to different psychiatric conditions beyond post-traumatic stress disorder (PTSD), and an increasing number of studies have evaluated its effect on depression. To date, no quantitative synthesis of the efficacy of EMDR on depression has been conducted. Objective: To meta-analytically review the studies on EMDR for depression as the primary target for treatment. Method: Studies with a controlled design evaluating the effect of EMDR on depression were searched on six electronic databases (PubMed, Embase, CINAHL, PsycINFO, Cochrane database, and Francine Shapiro Library) and then selected by two independent reviewers. A systematic review and meta-analysis was conducted. Results: Eleven studies were included for qualitative synthesis. Nine studies were included in the meta-analysis, involving 373 participants. The overall effect size of EMDR for depressive symptoms is large (n = 9, Hedges' g = - 1.07; 95%CI [-1.66; - 0.48]), with high heterogeneity (I ² = 84%), and corresponds to a 'number needed to treat' of 1.8. At follow-up (range 3-6 months), the effect remains significant but moderate (n = 3, Hedges' g = - 0.62; 95%CI [-0.97; - 0.28]; I ² = 0%). The effect of EMDR compared with active controls is also moderate (n = 7, g = - 0.68; 95%CI [-0.92; - 0.43]; I ² = 0%). No publication bias was found, although the results are limited by the small number and poor methodological quality of the included studies. Conclusions: Review findings suggest that EMDR may be considered an effective treatment for improving symptoms of depression, with effects comparable to other active treatments. However, findings need to be interpreted in light of the limited number of the studies and their quality. Further research is required to understand the longer-term of effects EMDR in treating depression and preventing depression relapse. Protocol registration: PROSPERO (CRD42018090086).

The Current Status of EMDR Therapy, Specific Target Areas, and Goals for the Future

While eye movement desensitization and reprocessing (EMDR) is considered an evidence-based treatment for posttraumatic stress disorder (PTSD) in adults, there are differences as to how various international treatment guidelines judge the strength of this evidence base. Furthermore, in areas other than adult PTSD, major guidelines differ even more as to the strength of the evidence base and when to use EMDR. In 2019, the Council of Scholars: The Future of EMDR Therapy Project was initiated. Several working groups were established, with one assigned to the focus area of research. This article is a product of that working group. Firstly the group concluded that there were five areas where there was some base that EMDR was effective, but more data were needed to increase the likelihood that it would be considered in future international treatment guidelines. These areas were PTSD in children and adolescents, early EMDR interventions, combat PTSD, unipolar depression, and chronic pain. In addition, research into cost-effectiveness of EMDR therapy was identified as one of the priorities. A hierarchical system was used for classifying and rating evidence in the focus areas. After assessing the 120 outcome studies pertaining to the focus areas, we conclude that for two of the areas (i.e., PTSD in children and adolescents and EMDR early interventions research) the strength of the evidence is rated at the highest level, whereas the other areas obtain the second highest level. Some general recommendations for improving the quality of future research on the effectiveness of EMDR therapy are formulated.

The effect of eye movement desensitization and reprocessing on the fear of hypoglycemia in type 2 diabetic patients: a randomized clinical trial

BACKGROUND

The fear of hypoglycemia leads to psychological symptoms in patients with diabetes type 2. In this research, the effects of EDMR on the fear of hypoglycemia in patients with diabetes type 2 were examined.

METHODS

A clinical trial study was carried out with participation of 72 patients who had diabetes type 2 in Velayat Hospital. The participants were randomly assigned into control and intervention groups. The intervention group received EMDR. The required information was gleaned using a questionnaire of fear of hypoglycemia, intensity of hypoglycemia, and demographics filled out before the intervention, and 1 month and 3 months after it. The data were analyzed using descriptive statistics on SPSS Version 23. For comparison of fear of hypoglycemia in intervention and control groups, repeated measure ANOVA and Cohen d test were used.

RESULTS

The mean age of the participants in the intervention group was 43.17 ± 10.55 and in the control group was 45.86 ± 13.6. In this study, without considering the potential disruptors in the incorrect model, the intervention caused a reduction of 15 points 1 month after the completion of the intervention and a reduction of 17 points 3 month after the completion of the intervention on the scale of fear of hypoglycemia; but post-correction of potential disruptors, intervention caused a reduction of 19.5 scores 1 month after the completion and a reduction of 20.3 scores 3 months after the intervention .

CONCLUSIONS

The EMDR can be used as a non-pharmaceutical treatment method to treat and alleviate the fear of hypoglycemia in type 2 diabetes patients.

Efficacy of the 'Children in Disaster: Evaluation and Recovery (CIDER)' Protocol for Traumatized Adolescents in Korea

BACKGROUND

We aimed to evaluate the feasibility of trauma-focused group therapy in adolescents exposed to traumatic events in Korea.

METHODS

We recruited 22 adolescents (mean age, 16 years; standard deviation, 1.43; range, 13-18 years). Children in Disaster: Evaluation and Recovery (CIDER) V1.0 is a trauma-focused group therapy comprising eight 50-minute-long sessions. The effectiveness of the intervention was evaluated using the Korean version of the Children's Response to Traumatic Events Scale-Revised (K-CRTES-R), the Beck Depression Inventory (BDI), the State Anxiety Inventory for Children (SAIC), and the Pediatric Quality of Life Inventory (PedsQL). The data were analyzed by the Wilcoxon signed-rank test.

RESULTS

A significant improvement was revealed in trauma-related symptom scores (Z = -2.85, P < 0.01), depressive symptom scores (Z = -2.35, P < 0.05) and quality of life scores (Z = -3.08, P < 0.01). Additionally, a marginally significant improvement was found in anxiety symptom scores (Z = -1.90, P = 0.058).

CONCLUSION

CIDER is a potentially effective intervention for adolescents exposed to traumatic events. Larger controlled trials are needed.
