The effect of eye movement desensitization and reprocessing (EMDR) on abdominal pain in patients with irritable bowel syndrome (IBS): a study protocol for a randomized controlled trial (EMDR4IBS).

BACKGROUND: Irritable bowel syndrome (IBS) is a highly prevalent disorder for which treatment options such as medication, diets, and hypnotherapy either have shown limited effect or relieve symptoms in only a limited subset of patients. Abdominal pain is the key criterion for the diagnosis and is deemed the most distressing IBS symptom, and the most disruptive of everyday life. A growing body of research demonstrates the effect of Eye Movement Desensitization and Reprocessing (EMDR) on chronic pain. EMDR is known as a safe and successful treatment for disorders in which unresolved traumatic memories play a role in the cause or maintenance of symptoms. In IBS, activated memories may increase pain through pain flashbacks and the stress generated by unresolved memories. The aim of this study is to ascertain whether applying EMDR to traumatic memories including pain memories will reduce abdominal pain in IBS patients. METHODS: This study is a randomized controlled trial which will be conducted at a city hospital in the Netherlands. Adult patients with considerable IBS pain (pain intensity at least 60/100 during at least 5/10 days) will be randomly assigned to either EMDR therapy or the wait list. We aim to include 34 participants. The EMDR condition comprises seven sessions, around 90 min in length delivered weekly, the first of which is a case conceptualization session. All participants will be assessed at baseline, post-treatment, and at 3 months follow-up. The primary outcome measure is pain intensity on a Likert scale which is self-reported daily during a 2-week period. Secondary outcomes include similar daily ratings on other IBS symptoms and reported hindrance of valued activities, and also standardized questionnaires on IBS symptoms and Quality of Life. Data will be analyzed by a Linear Mixed Effects Model for repeated measures. DISCUSSION: The results are expected to gain insight into the effectiveness of EMDR treatment on abdominal pain in IBS. As there are very few effective treatment options for IBS-related abdominal pain, this study could have important implications for clinical practice.

Development of a body dysmorphic disorder screener for DSM-5 (BDDS-5).

Early identification of individuals with Body dysmorphic disorder (BDD) is essential to direct them to appropriate care and to reduce the chance of developing or maintaining comorbid psychiatric disorders (like an eating disorder (ED)). The present study aimed to develop a simple screener, the Body Dysmorphic Disorder Screener for DSM-5 (BDDS-5), to overcome existing screeners' limitations and test its psychometric properties. The BDDS-5 consists of 12 statements with dichotomous answer options. Specific attention is paid to the readability of the screener for those with lower reading skills. Additional eating disorder screening questions (S section) were added to investigate whether these questions are necessary for detecting potential BDD cases. Finally, the factor structure, internal consistency, and validity of the BDDS-5 were examined within populations with a high risk of screening positive for BDD or ED. Principal axis factor analysis showed that two factors accounted for 63.5% of the variance. The factor analysis was based on polychoric correlation. Based on the BDDS-5, 33 persons (14% of N = 235) were screened as likely BDD cases. Nineteen persons were excluded as potential BDD cases based on the eating disorder related question (question D). Based on the S-section, this turned out to be largely correct for the majority, however, in 8% (n = 4) of the cases BDD was probably missed. The convergent validity appeared to be high (r > 0.80) with three other BDD measures. The BDDS-5 is a valid and widely applicable screener for BDD that may help in the early detection of BDD. The BDDS-5 uses simple wording and is thus suitable for people 8 years and older.

Efficacy of eye movement desensitization and reprocessing therapy for fear of cancer recurrence among cancer survivors: a randomized single-case experimental design.

Background: Fear of cancer recurrence (FCR) is one of the greatest problems with which cancer survivors have to deal. High levels of FCR are characterized by intrusive thoughts about cancer-related events and re-experiencing these events, avoidance of reminders of cancer, and hypervigilance, similar to post-traumatic stress disorder (PTSD). Eye movement desensitization and reprocessing (EMDR) therapy focuses on these images and memories. It is effective in reducing PTSD and may be effective in reducing high levels of FCR.Objective: The aim of the present study is to investigate the effectiveness of EMDR for severe FCR in breast and colorectal cancer survivors.Method: A multiple-baseline single-case experimental design (n = 8) was used. Daily repeated measurements for FCR were taken during the baseline phase and treatment phase, post-treatment, and at the 3 month follow-up. Participants answered the Cancer Worry Scale (CWS) and the Fear of Cancer Recurrence Inventory, Dutch version (FCRI-NL) five times, i.e. at the start and at the end of each phase (baseline, treatment, post-treatment, and follow-up). The study was prospectively registered at clinicaltrials.gov (NL8223).Results: Visual analysis and effect size calculation by Tau-U were executed for the daily questionnaire on FCR. The weighted average Tau-U score was .63 (p < .01) for baseline versus post-treatment, indicating large change, and .53 (p < .01) between baseline and follow-up, indicating moderate change. The scores on the CWS and FCRI-NL-SF decreased significantly from baseline to follow-up.Conclusion: The results seem promising for EMDR therapy as a potentially effective treatment for FCR. Further research is recommended.

Patients who experience high fear of cancer recurrence (FCR) often have intrusive memories and images about (future) cancer-related events.Eye movement desensitization and reprocessing (EMDR) therapy can focus on these intrusions.EMDR therapy is found to be a promising therapy for patients experiencing high FCR.

Treatment course and its predictors in patients with somatoform disorders: A routine outcome monitoring study in secondary psychiatric care.

AIM: Somatoform disorders are common and often chronic. It would be helpful to distinguish those patients who are likely to have a positive treatment course from those who are likely to follow a negative course. Such studies of different somatoform disorders are scarce, especially in secondary psychiatric care. This study examined the 6-month treatment course of psychological, physical symptoms, and functioning, and its predictors in a naturalistic sample of secondary psychiatric care outpatients with somatoform disorders. METHOD: The present study used routine outcome monitoring data of patients with somatoform disorders regarding their 6-month treatment course of psychological and physical symptoms as well as functioning. The following patient groups were included: total group of somatoform disorders (N = 435), and undifferentiated somatoform disorder (N = 242), pain disorder (N = 102), body dysmorphic disorder (N = 51), and hypochondriasis (N = 40). Measures were Mini-International Neuropsychiatric Interview plus, Brief Symptom Inventory, Montgomery-Ǻsberg Depression Rating Scale, Brief Anxiety Scale, Short Form Health Survey 36, and Physical Symptom Checklist (PSC). RESULTS: The study population generally showed high co-morbidity, especially with anxiety and mood disorders. The PSC total score, body dysmorphic disorder, and hypochondriasis were significant predictors for the treatment course of symptoms (Brief Symptom Inventory), whereas the PSC total score was the only significant predictor for the course of functioning (Short Form Health Survey 36). CONCLUSION: Secondary psychiatric care outpatients with somatoform disorders showed high co-morbidity with anxiety and mood disorders, and an unfavourable 6-month course of both symptoms and functioning. Clinical implications are discussed, such as additional treatment of co-morbidity in somatoform disorders.

Routine outcome monitoring in the Netherlands: practical experiences with a web-based strategy for the assessment of treatment outcome in clinical practice.

Routine outcome monitoring (ROM) is a method devised to systematically collect data on the effectiveness of treatments in everyday clinical practice. ROM involves documenting the outcome of treatments through repeated assessments. Assistants are employed who perform a baseline assessment comprising a standardized diagnostic interview, administration of rating scales and completion of several self-report measures by the patient. At fixed time intervals, assessments are repeated. Dedicated Web-based software has been developed to assist in this task. ROM informs therapists and patients on the severity of the complaints at intake, and the waxing and waning of symptoms over the course of treatment. Researchers can use ROM for effectiveness research, and managers can use it for benchmarking. The use of ROM for research is illustrated by presenting data on the diagnostic status of patients participating in ROM and data on treatment outcome of a subgroup of patients (with panic disorder) in our database. The results show that implementation of ROM is feasible, and after some initial reservations, most therapists now consider ROM to be a necessary and important adjunct to the clinical treatment. In addition, ROM furthers research as the data can be used to study the phenomenology of psychiatric disorders and the outcome of treatments delivered in everyday practice.

Pre-adult versus adult onset major depressive disorder in a naturalistic patient sample: the Leiden Routine Outcome Monitoring Study.

BACKGROUND: Pre-adult onset of major depressive disorder (MDD) may predict a more severe phenotype of depression. As data from naturalistic psychiatric specialty care settings are scarce, we examined phenotypic differences between pre-adult and adult onset MDD in a large sample of consecutive out-patients. METHOD: Altogether, 1552 out-patients, mean age 39.2 ± 11.6 years, were diagnosed with current MDD on the Mini-International Neuropsychiatric Interview Plus diagnostic interview as part of the usual diagnostic procedure. A total of 1105 patients (71.2%) had complete data on all variables of interest. Pre-adult onset of MDD was defined as having experienced the signs and symptoms of a first major depressive episode before the age of 18 years. Patients were stratified according to the age at interview (20-40/40-65 years). Correlates of pre-adult onset were analysed using logistic regression models adjusted for age, age squared and gender. RESULTS: Univariate analyses showed that pre-adult onset of MDD had a distinct set of demographic (e.g. less frequently living alone) and clinical correlates (more co-morbid DSM-IV - Text Revision diagnoses, more social phobia, more suicidality). In the multivariate model, we found an independent association only for a history of suicide attempts [odds ratio (OR) 3.15, 95% confidence intervals (CI) 1.97-5.05] and current suicidal thoughts (OR 1.81, 95% CI 1.26-2.60) in patients with pre-adult versus adult onset MDD. CONCLUSIONS: Pre-adult onset of MDD is associated with more suicidality than adult onset MDD. Age of onset of depression is an easy to ascertain characteristic that may help clinicians in weighing suicide risk.

Treatment of chronic phantom limb pain using a trauma-focused psychological approach.

BACKGROUND: Chronic phantom limb pain (PLP) is a disabling chronic pain syndrome for which regular pain treatment is seldom effective. Pain memories resulting from long-lasting preamputation pain or pain flashbacks, which are part of a traumatic memory, are reported to be powerful elicitors of PLP. OBJECTIVE: To investigate whether a psychological treatment directed at processing the emotional and somatosensory memories associated with amputation reduces PLP. METHODS: Ten consecutive participants (six men and four women) with chronic PLP after leg amputation were treated with eye movement desensitization and reprocessing (EMDR). Pain intensity was assessed during a two-week period before and after treatment (mean number of sessions = 5.9), and at short- (three months) and long-term (mean 2.8 years) follow-up. RESULTS: Multivariate ANOVA for repeated measures revealed an overall time effect (F[2, 8]=6.7; P<0.02) for pain intensity. Pairwise comparison showed a significant decrease in mean pain score before and after treatment (P=0.00), which was maintained three months later. All but two participants improved and four were considered to be completely pain free at three months follow-up. Of the six participants available at long-term follow-up (mean 2.8 years), three were pain free and two had reduced pain intensity. CONCLUSIONS: These preliminary results suggest that, following a psychological intervention focused on trauma or pain-related memories, substantial long-term reduction of chronic PLP can be achieved. However, larger outcome studies are required.

Distinguishing between depression and anxiety: a proposal for an extension of the tripartite model.

AIM: The aim of the current study was to develop scales that assess symptoms of depression and anxiety and can adequately differentiate between depression and anxiety disorders, and also can distinguish within anxiety disorders. As point of departure, we used the tripartite model of Clark and Watson that discerns three dimensions: negative affect, positive affect and physiological hyperarousal. METHODS: Analyses were performed on the data of 1449 patients, who completed the Mood and Anxiety Symptoms Questionnaire (MASQ) and the Brief Symptom Inventory (BSI). From this, 1434 patients were assessed with a standardized diagnostic interview. RESULTS: A model with five dimensions was found: depressed mood, lack of positive affect, somatic arousal, phobic fear and hostility. The scales appear capable to differentiate between patients with a mood and with an anxiety disorder. Within the anxiety disorders, somatic arousal was specific for patients with panic disorder. Phobic fear was associated with panic disorder, simple phobia and social anxiety disorder, but not with generalized anxiety disorder. CONCLUSIONS: We present a five-factor model as an extension of the tripartite model. Through the addition of phobic fear, anxiety is better represented than in the tripartite model. The new scales are capable to accurately differentiate between depression and anxiety disorders, as well as between several anxiety disorders.

[Prevalence and comorbidity of body dysmorphic disorder in psychiatric outpatients]. / Prevalentie en comorbiditeit van de stoornis in de lichaamsbeleving bij poliklinische psychiatrische patiënten.

BACKGROUND: Body dysmorphic disorder (BDD) is a somatoform disorder, characterized by a patient's preoccupation with the belief that some aspect of his/her physical appearance is abnormal. The prevalence of BDD in the general population is 0.7 - 1.7%. The prevalence of BDD in patients attending a Dutch general outpatient clinic has never been examined. AIM: Examine the prevalence of BDD in patients attending a Dutch general outpatient clinic. METHOD: All patients aged 18 to 65 who were referred between September 2003 and July 2007 to six general outpatients clinics for treatment of a depressive disorder, an anxiety disorder, or a somatoform disorder were assessed with the Mini International Neuropsychiatric Interview (mini). Patients with BDD were also assessed by means of the Body Dysmorphic Disorder - Yale- Brown Obsessive Compulsive Scale (BDD-YBOCS). results BDD was diagnosed in 45 out of 5848 patients (0.8% (0.6-1.0%)). The average age of these patients was 31.1. years and 69% were female. A comorbid depressive disorder was present in 35 patients (78%) and a comorbid anxiety disorder in 26 patients (58%). Of the anxiety disorders, social phobia was the most common, with a prevalence of 27%. The average score on the BDD-YBOCS was 22.5 points. The BDD-YBOCS score was significantly higher in patients with a comorbid obsessive-compulsive disorder (35.7 points; p = 0.01). CONCLUSION: The prevalence of BDD in psychiatric outpatients who were referred for treatment of a depressive disorder, an anxiety disorder, or a somatoform disorder was 0.8%. There was a high comorbidity of BDD with depressive and anxiety disorders.

Preoccupation with one's appearance: a motivating factor for cosmetic dental treatment?

BACKGROUND: It has been estimated that among patients presenting for cosmetic treatments up to 15% suffer from Body Dysmorphic Disorder (BDD), a psychiatric condition characterised by a preoccupation with an imagined defect in appearance. OBJECTIVES: The main purpose of the current study was to establish the relationship between presence of BDD characteristics and interest in aesthetically motivated dental treatments. METHODS: Data were obtained by means of a survey within a sample of 879 Dutch citizens of 16 years and older. Characteristics of BDD were assessed based on DSM-IV criteria. RESULTS: Only one of the BDD features (ie a preoccupation with a defect of appearance) emerged as a significant predictor of undergoing cosmetic dental treatments. Patients with such preoccupation were nine times more likely to consider tooth whitening, and six times more likely to consider orthodontic treatment. They were also five times more likely to be dissatisfied about their most recent treatment. CONCLUSIONS: The results suggest that preoccupation with one's physical appearance is a motivating factor for undergoing certain types of cosmetic dental procedures.

Clinical trial: short- and long-term benefit of relaxation training for irritable bowel syndrome.

BACKGROUND: Psychotherapy is effective in treating irritable bowel syndrome, but the effect of relaxation training, a brief psychological group intervention, is not known. AIM: To determine the efficacy of relaxation training in a large cohort of irritable bowel syndrome patients. METHODS: Ninety-eight irritable bowel syndrome patients were included in this randomized controlled trial. Forty-six patients received standard medical care (CON) and 52 received four 90-min sessions of relaxation training in small groups in addition to standard medical care. Irritable bowel syndrome symptom severity, medical consumption and quality of life were assessed at baseline in patients and in 38 healthy controls and evaluated in patients at 3, 6 and 12 months after intervention. RESULTS: Irritable bowel syndrome symptom severity was significantly reduced in the relaxation training group compared to CON at 3, 6 and 12 months after treatment (time-by-treatment interaction, P = 0.002). The number needed to treat for long-term improvement was 5. Quality of life had improved (general health, P = 0.017; health change, P = 0.05). Frequency of doctor visits was reduced (P = 0.039). CONCLUSIONS: Relaxation training is a brief group intervention that significantly improves symptom severity, general health perception and medical consumption in irritable bowel syndrome patients immediately after, as well as 6 and 12 months after intervention.

[Popularity of aesthetic dental treatments. Results of a national study in the Netherlands]. / De populariteit van esthetische behandelingen. resultaten van een landelijk onderzoek.

There are indications of a growing public interest in aesthetic dental treatments. For want of reliable data, a group of 907 randomly selected Dutch individuals was questioned in order to give this apparent tendency a foundation in figures. The results of this study show that about 25% of the respondents received aesthetic dental treatment at some time, about 8% was treated during the past year, and almost 8% intended to undergo aesthetic dental treatment in the coming year. In this respect, tooth whitening was found to be the most popular treatment. The results of this study suggest that there is a positive attitude towards aesthetic dentistry and that women take a greater interest in it than men. Whether this interest will lead to a rise in the number of actual aesthetic dental treatments is still unclear.

[Burning-mouth syndrome: consideration of maintenance factors]. / Het syndroom van mondbranden: aandacht voor instandhoudende factoren.

Burning-mouth syndrome is characterised by a number of complaints of which the burning sensation in the mouth is the most important but cannot be explained by known medical causes. Although psychological factors can predispose for or trigger physical symptoms without a medical explanation, treatment directed at the proposed psychological causes has not proven to be very effective and is not acceptable for most patients. Treatment directed at reducing the consequences of the complaint that could play a role in maintaining the problem is, however, effective and is accepted by almost all patients. Consequences that could maintain the burning-mouth syndrome are anxiety, depression, selective attention, and measures taken to find relief but which can irritate the oral mucosa. The treating physician should inform the patient and help him to change his behaviour. If patients have become depressed or very anxious as a consequence of the complaints they should be referred to a cognitive-behaviour therapist specialised in the treatment of patients with physical symptoms without a medical explanation.
