Predictors of somatic symptoms in depressive disorder

We explored the relative contribution of potential psychological predictors of somatic symptoms in outpatients with major depressive disorder, including; 1) severity of depression; 2) general anxiety; 3) hypochondriacal worry; 4) somatosensory amplification; and, 5) alexithymia by sampling 100 consecutive outpatients with DSM-IV diagnoses of major depressive disorder attending the psychiatry clinics of general hospitals in Turkey. The subjects were rated by clinicians on depressive symptomatology (Hamilton Depression Rating Scale), and anxiety (Hamilton Anxiety Scale), and completed self-report measures of Hypochondriacal worry (7-item version of the Whiteley Index), the Somatosensory Amplification Scale, and the Toronto Alexithymia Scale. Multivariate models tested the independent contribution of each of the scales to the level of somatic symptoms as measured by a modified version of the SCL-90 somatization scale. At the bivariate level, somatic symptoms were associated with female gender and lower educational level, as well as the Hamilton Depression and Anxiety scales, the Whitely Index, and the Somatosensory Amplification and Alexithymia scales. In multiple regression models incorporating all variables, female gender and higher scores on the anxiety, somatosensory amplification and alexithymia scales all made independent contributions to the level of somatic symptoms and accounted for 54% of the variance. Therefore, somatic symptoms in depression are related to concomitant anxiety, tendency to amplify somatic distress, and difficulty identifying and communicating emotional distress. However, these factors do not account for the tendency for women to report more somatic symptoms.     

Anxiety and depression in patients with the abdominal pelvic pain syndrome

The authors matched gynecologic patients with the abdominal pelvic pain syndrome (N = 41) with other gynecologic patients. They administered to both groups self-rating scales of anxiety, depression, anger-hostility, and somatization of the Hopkins Symptom Checklist and of the Symptom Questionnaire, a questionnaire about disruptions in early home life, and a questionnaire of recent stressful events. Patients with pain rated themselves on the average significantly more anxious, depressed, and hostile, and had more somatic symptoms than other patients; 56% of the patients with pain rated themselves within the normal ranges on all scales. There were no significant differences between the two groups in reports of disruptions of early home life and recent losses. The findings are consistent with the view that patients with the abdominal pelvic pain syndrome are psychologically a heterogeneous group; in many patients, depression and anxiety may be consequences of persistent pain.     

A symptom questionnaire

The Symptom Questionnaire (SQ) is a yes/no questionnaire with brief and simple items. It contains state scales of depression, anxiety, anger-hostility, and somatic symptoms. It was developed from earlier versions to make the scales more sensitive for clinical research. The scales have been extensively validated. The psychometric properties of the SQ are somewhat different from those of similar scales. In double-blind, crossover studies, they tended to be more sensitive than other scales in discriminating between the effects of a psychotropic drug and placebo and were found to be highly sensitive in discriminating between distress levels of groups. In studies with small or moderately sized samples in which the sensitivity of scales is important or in populations that include subjects with poor verbal skills, the SQ seems to have advantages. The SQ is suitable for the measurement of distress and hostility in research and as a checklist in clinical work.     

Somatization: a spectrum of severity

OBJECTIVE: The DSM-III-R diagnosis of somatization disorder requires that a patient have a specific number of medically unexplained somatic symptoms. This number of symptoms was developed by committee consensus, and it is not clear whether patients with this specific number of symptoms can be differentiated from patients with lower but still substantial numbers of somatic symptoms. METHOD: Fifty-one percent of 767 high utilizers of two primary care clinics were identified as distressed by an elevated SCL anxiety, depression, or somatization scale score or by their primary care physician. The Diagnostic Interview Schedule (DIS) was completed on 119 distressed high utilizers who were randomly assigned to an intervention group in a controlled trial of psychiatric consultation. The 119 distressed high utilizers were separated into four categories according to the number of unexplained somatic symptoms found on the DIS and were compared on demographic, psychiatric distress, disability, medical, and health utilization variables. RESULTS: The data suggest that many clinical and behavioral features of somatization are significantly more common in patients with four to 12 medically unexplained somatic symptoms rather than changing dramatically at the diagnostic threshold for somatization disorder. The data also showed that patients who meet the DSM-III-R criteria for somatization disorder are severely ill and have a high burden of psychiatric illness and disability. CONCLUSIONS: The results suggest that the DSM-IV somatoform disorders section should include somatization disorder, an abridged definition of somatization disorder often associated with anxiety and depression, as well as a type of somatization associated with an adjustment disorder.     

Somatization and psychiatric disorder in the NIMH Epidemiologic Catchment Area study

OBJECTIVE: Somatization has often been viewed as a defense against awareness of emotional distress or as a masked version of depression. This report examines whether community residents with high levels of functional somatic symptoms also report overt psychological distress and whether somatization is associated with any specific psychiatric disorder. METHOD: Analyses used data from the community sample of the National Institute of Mental Health Epidemiologic Catchment Area (ECA) study, a population-based survey of psychiatric morbidity among more than 18,000 residents of five U.S. communities. RESULTS: Increasing number of somatization symptoms was strongly associated with overt expression of psychological distress and psychiatric symptoms. Among ECA respondents with five or more current functional somatic symptoms, 63% reported current psychological symptoms and 50% met criteria for a current psychiatric diagnosis (compared to 7% and 6%, respectively, among those with no current somatization symptoms). Somatization symptoms showed strongest associations with anxiety and depressive symptoms, intermediate association with symptoms of psychotic disorders, and weakest associations with symptoms of substance abuse and antisocial personality. CONCLUSIONS: ECA study respondents with high levels of somatization symptoms typically reported overt psychological distress, especially anxiety and depression. Patterns of response do not support a dissociation between physical and emotional symptoms. Functional somatic symptoms appear to be common expressions of distress instead of defenses against awareness.     

Prevalence,demographic and clinical characteristics of body dysmorphic disorder among psychiatric outpatients with mood,anxiety or somatoform disorders

Aims: To describe the prevalence, demographic and clinical characteristics of body dysmorphic disorder (BDD) compared with other psychiatric outpatients with a mood, anxiety or somatoform disorder. Method: Outpatients referred for treatment of a mood, anxiety or somatoform disorder were routinely assessed at intake. A structured interview (MINI-Plus), observer-based and self-rating instruments were administered by an independent assessor. Results: Among our sample of 3798 referred patients, 2947 patients were diagnosed with at least one DSM-IV mood, anxiety or somatoform disorder. Of these patients 1.8% (n = 54) met the diagnostic criteria for BDD. In comparison with other outpatients, patients with BDD were on average younger, less often married and were more often living alone. Highly prevalent comorbid diagnoses were major depression (in 46.3% of cases), social anxiety disorder (in 35.2% of cases) and obsessive–compulsive disorder (OCD) (in 16.7% of cases). Furthermore, patients with BDD had higher scores on the Clinical Global Impression of Severity (CGI-S) as well as lower scores on the Short Form 36 social role functioning. Conclusion: BDD is frequently associated with depression, social phobia and OCD. Patients with BDD have more distress and more impaired interpersonal functioning.     

Hypochondriacal concerns and somatic symptoms in patients with chronic airflow obstruction

In order to explore hypochondriacal concerns in patients with Chronic Airflow Obstruction (CAO) the authors administered the Illness Attitude Scales and the somatization, anxiety, depression and anger-hostility scales of the Hopkins Symptom Checklist to 50 patients with CAO and to matched family practice patients. Somatic symptoms were significantly correlated with fears of disease and hypochondriacal concerns in family practice patients, but were unrelated in CAO. Patients with CAO, although more anxious, depressed and with more severe somatic symptoms than family practice patients, had fewer hypochondriacal concerns. In this respect patients with CAO were unlike any other group previously studied.     

Psychiatric symptoms screening in the early stages of Parkinson’s disease

Psychiatric complaints are common in Parkinson’s disease (PD), and have a significant influence in disease outcome and quality of life. Little attention has been paid to psychiatric symptoms at early stage disease. We aimed to screen a population of early stage PD patients for psychiatric symptoms and to study the relation with motor and cognitive function. Thirty-six early stage PD patients underwent motor [Hoehn and Yahr (HY), Unified Parkinson’s Disease Rating Scale] and cognitive [Frontal Assessment Battery, Mini-Mental State Examination (MMSE)] assessment as well as general psychiatric [Symptom Check-List 90 (SCL-90-R)] and psychosis [Brief Psychiatric Rating Scale (BPRS)] screening. Relation between psychiatric domains scores was studied with principal component analysis. Relation between psychiatric, disease related, cognitive and motor function was assessed with bivariate correlation (Pearson). SCL-90-R scores were higher for somatization (significant scores in 66.7% of patients), depression (36.1%), anxiety (27%) and obsessive—compulsive symptoms (OCS) (52.8%). Scores were highly correlated, except for psychosis and phobia. Depression and anxiety were negatively correlated to MMSE score and dopaminergic doses, respectively. BPRS scores were higher for somatic concern, depression, anxiety and hallucinations. There was segregation between depression, anxiety, hallucinations, other positive psychotic symptoms and negative psychotic symptoms. Depression was related to MMSE score. We found a high prevalence of psychiatric complaints in PD patients, mostly related to depression, anxiety, somatization and OCS. Hallucinations were also frequent, but not associated to cognitive function or dopaminergic doses, suggesting a different physiopathological background.     

The relation between anger management style, mood and somatic symptoms in anxiety disorders and somatoform disorders

The objective of this study was to examine the relationship between anger management style, depression, anxiety and somatic symptoms in anxiety disorder and somatoform disorder patients. The subjects comprised 71 patients with anxiety disorders and 47 with somatoform disorders. The level of anger expression or anger suppression was assessed by the Anger Expression Scale, the severity of anxiety and depression by the Symptom Checklist-90-Revised (SCL-90-R) anxiety and depression subscales, and the severity of somatic symptoms by the Somatization Rating Scale and the SCL-90-R somatization subscale. The results of path analyses showed that anger suppression had only an indirect effect on somatic symptoms through depression and anxiety in each of the disorders. In addition, only anxiety had a direct effect on somatic symptoms in anxiety disorder patients, whereas both anxiety and depression had direct effects on somatic symptoms in somatoform disorder patients. However, the anxiety disorder group showed a significant negative correlation between anger expression and anger suppression in the path from anger-out to anger-in to depression to anxiety to somatic symptoms, unlike the somatoform disorder group. The results suggest that anger suppression, but not anger expression, is associated with mood, i.e. depression and anxiety, and somatic symptoms characterize anxiety disorder and somatoform disorder patients. Anxiety is likely to be an important source of somatic symptoms in anxiety disorders, whereas both anxiety and depression are likely to be important sources of somatic symptoms in somatoform disorders. In addition, anger suppression preceded by inhibited anger expression is associated with anxiety and somatic symptoms in anxiety disorders.     

Fluvoxamine treatment of obsessive-compulsive disorder

Sixteen outpatients who met DSM-III criteria for obsessive-compulsive disorder completed a 20-week double-blind, crossover trial with fluvoxamine and placebo. Thirteen (81%) improved with fluvoxamine, while three (19%) improved with placebo. Fluvoxamine treatment was associated with significant improvement on measures of obsessive-compulsive symptoms, anxiety, and depression. Depressed subjects' improvement on obsessive-compulsive measures correlated with improvement in symptoms of depression. Nondepressed subjects also showed improvement on measures of obsessive-compulsive symptoms. In this trial, fluvoxamine was an effective and safe treatment for obsessive-compulsive disorder.     

Three forms of somatization in primary care: prevalence, co-occurrence, and sociodemographic characteristics

Three definitions of somatization were operationalized: (a) high levels of functional somatic distress, measured by the Somatic Symptom Index (SSI) of the Diagnostic Interview Schedule; (b) hypochondriasis measured by high scores on a measure of illness worry in the absence of evidence for serious illness; and (c) exclusively somatic clinical presentations among patients with current major depression or anxiety. Of 685 patients attending two family medicine clinics, 26.3% met criteria for one or more forms of somatization. While DSM-III somatization disorder had a prevalence of only 1% in this population, 16.6% of the patients met abridged criteria for subsyndromal somatization disorder (SSI 4,6). Hypochondriacal worry had a prevalence of 7.7% in the clinic sample. Somatized presentations of current major depression or anxiety disorder had a prevalence of 8%. The three forms of somatization were associated with different sociodemographic and illness behavior characteristics. A majority of patients met criteria for only one type of somatization, suggesting that distinct pathogenic processes may be involved in each of the three types.     

Hostility, somatic symptoms, and hypochondriacal fears and beliefs

The authors administered self-rating scales of anger-hostility, somatic symptoms, and hypochondriacal fears and beliefs to seven groups of patients and nonpatients. Somatic symptoms were positively correlated with anger-hostility and were negatively correlated with feelings of friendliness; the correlation coefficients ranged from low to moderately high and were significant in most groups. Somatic symptoms tended to be associated more strongly with symptoms of anxiety and depression than with those of hostility. The associations of hypochondriacal fears and beliefs with hostility were inconsistent, varied between groups and with the concern measured. The findings do not support the view that anger or hostility are main or specific etiological factors either in somatization or in hypochondriacal fears or beliefs.     

Research diagnostic criteria (RDC) mental disorder and self-reported symptoms in outpatients with complex partial seizures (CPS)

Fifteen outpatients with complex partial seizures (CPS) were investigated to assess the presence and severity of affective disorders, anxiety, and cognitive deficits. Forty percent of patients met the criteria for an affective disorder according to Research Diagnostic Criteria (RDC). Patients scored significantly higher than controls on the Beck Depression Inventory (p less than 0.001), on the State and Trait Anxiety Inventory (p less than 0.01, p less than 0.05), on the Symptom Questionnaire scales for anxiety (p less than 0.005), depression (p less than 0.01), and somatization (p less than 0.01). They also scored significantly lower than controls on the Mini-Mental State Examination for grading cognitive state (p less than 0.05). Epileptic patients with RDC diagnosis of depression reported significantly more symptoms of depression, anxiety, somatization, and less sociability and trustfulness than epileptic patients without concurrent mental disorders. Implications of these results are discussed.     

Cognitive behavioral therapy for psychogenic nonepileptic seizures

Treatment trials for psychogenic nonepileptic seizures (PNES) are few, despite the high prevalence and disabling nature of the disorder. We evaluated the effect of cognitive behavioral therapy (CBT) on reduction of PNES. Secondary measures included psychiatric symptom scales and psychosocial variables. We conducted a prospective clinical trial assessing the frequency of PNES in outpatients treated using a CBT for PNES manual. Subjects diagnosed with video/EEG-confirmed PNES were treated with CBT for PNES conducted in 12 weekly sessions. Seizure calendars were charted prospectively. Twenty-one subjects enrolled, and 17 (81%) completed the CBT intervention. Eleven of the 17 completers reported no seizures by their final CBT session. Mean scores on scales of depression, anxiety, somatic symptoms, quality of life, and psychosocial functioning showed improvement from baseline to final session. CBT for PNES reduced the number of PNES and improved psychiatric symptoms, psychosocial functioning, and quality of life.     

Measurement of subclinical changes during lithium prophylaxis: a longitudinal study

Psychological distress was observer-rated with the Brief Psychiatric Rating Scale (BPRS) and self-rated with the Symptom Questionnaire (SQ) every other week for a 6-month period in 9 apparently remitted bipolar patients attending a lithium clinic. Substantial clinical fluctuations in psychopathology were observed with both rating methods. Compared to normal control subjects, patients suffering from bipolar disorder displayed significantly higher BPRS and SQ anxiety, somatization and total distress scores.     

Hypochondriacal concerns and somatization in panic disorder

To clarify the relationship between panic disorder and the symptoms of hypochondriasis and somatization, we evaluated these symptoms and diagnoses in patients attending an Anxiety Disorders Clinic. Structured clinical interviews, self-report measures, and symptom diaries were used to assess 21 patients with panic disorder, 23 patients with social phobia, and 22 control subjects with no psychiatric disorders. Ten of the patients with panic disorder (48%) also met DSM-IV criteria for hypochondriasis, whereas only one of the patients with social phobia and none of the healthy control subjects met the criteria for this diagnosis. None of the participants met DSM-IV criteria for somatization disorder, even though both anxiety groups reported high levels of somatic symptoms. The panic disorder group reported higher levels of fear about illness and disease conviction and endorsed more somatic symptoms than did the other groups. A higher proportion of panic disorder patients reported previously diagnosed medical conditions (48%) as compared with patients with social phobia (17%) or healthy control subjects (14%). The panic disorder patients with DSM-IV hypochondriasis obtained higher scores on measures of hypochondriacal concerns, somatization, blood–injury phobia, and general anxiety and distress than did the panic disorder patients without hypochondriasis. The results suggest a strong association between panic disorder and hypochondriasis. Depression and Anxiety 6:78–85, 1997. © 1997 Wiley-Liss, Inc.     

Efficacy of fluvoxamine in the treatment of major depression with comorbid anxiety disorders.

BACKGROUND: Major depression with comorbid anxiety disorder is associated with poor antidepressant outcome compared with major depression without comorbid anxiety disorder. The purpose of our study was to assess changes in depressive symptoms and anxiety levels in outpatients with major depression with comorbid anxiety disorder following 12 weeks of open treatment with fluvoxamine. METHOD: We enrolled 30 outpatients (mean +/- SD age = 39.4 +/- 11.3 years; 16 women and 14 men) with DSM-IV major depressive disorder accompanied by one or more current comorbid DSM-IV anxiety disorders in our study. Patients were treated openly with fluvoxamine initiated at 50 mg/day, with an upward titration to a maximum of 200 mg/day (mean +/- SD dose = 143 +/- 45 mg/day). Efficacy assessments included the 17-item Hamilton Rating Scale for Depression (HAM-D-17) and Clinical Global Impressions-Severity of Illness (CGI-S) and Improvement (CGI-I) scales for both depression and anxiety. Intent-to-treat analysis was used to assess outcome. RESULTS: The mean +/- SD number of comorbid anxiety disorders per patient was 2.1 +/- 1.1. Following fluvoxamine treatment, the mean +/- SD HAM-D-17 score dropped from 20.2 +/- 3.3 to 1 1.0 +/- 7.0 (p < .0001). The mean +/- SD depression CGI-S score dropped from 4.0 +/- 0.6 to 2.4 +/- 1.1 (p < .0001), and the mean +/- SD anxiety CGI-S score decreased from 4.1 +/- 0.8 to 2.5 +/- 1.2 (p < .0001). Eighteen (60%) of the 30 patients had CGI-I scores < or = 2 for both anxiety and depression at endpoint, with 53% showing a > or = 50% reduction in HAM-D-17 scores at endpoint. CONCLUSION: Although preliminary, our findings suggest that fluvoxamine is effective in treating outpatients with major depression with comorbid anxiety disorder, having a significant effect on both depression and anxiety symptoms. Further double-blind, placebo-controlled trials are needed, in a larger sample, to confirm our findings.     

Association between defense mechanisms and psychiatric symptoms in North Korean Refugees

ObjectiveDefense mechanism may contribute to psychiatric symptoms. Refugees are vulnerable to various psychiatric symptoms, such as depression, anxiety, somatization, and those associated with post-traumatic stress disorder (PTSD), due to their traumatic or stressful experiences. We aimed to investigate the mediating role of each defense mechanism in the occurrence of specific psychiatric symptoms in North Korean refugees.MethodAmong 213 North Korean refugees initially recruited, 201 completed the following questionnaires: the Defense Style Questionnaire, the Center for Epidemiological Studies-Depression Scale (CES-D), the State–Trait Anxiety Inventory-State (STAI-S), the somatization subscale of Symptom Check-List-90-Revised (SCL-90-R), and the Impact of Event Scale-Revised (IES-R). Stepwise regression analysis was performed to determine the defense mechanisms more predominantly associated with specific psychiatric symptoms after controlling for age, sex, number of traumatic experiences, and other psychiatric symptoms (depressive symptoms and/or anxiety).ResultsHigher levels of depression were independently predicted by greater use of resignation. More use of acting out and less use of humor and sublimation independently predicted higher levels of anxiety. Somatization was independently predicted by more use of inhibition. PTSD symptoms were independently predicted by more use of undoing and isolation.ConclusionsSpecific psychiatric symptoms were associated with specific defense mechanisms in North Korean refugees. Our findings suggest that the manifest psychiatric symptoms of refugees may be mediated by their dominant defense mechanism.     

The frequency of the psychiatric symptoms in the patients with dyspepsia at a university hospital

OBJECTIVE: According to the psychiatric hypothesis, the symptoms of dyspepsia may be due to depression, anxiety or a somatization disorder. We investigated the frequency of psychiatric symptoms in patients undergoing endoscopic procedures with dyspepsia, either with or without pathological findings, and compared this with control subjects without dyspeptic symptoms. METHODS: Ninety patients with dyspeptic symptoms and 90 control subjects participated in the study. Both the patients and the controls were asked to complete a questionnaire about socio-demographic characteristics, the Turkish version of the Spielberger State-Trait Anxiety Inventory (STAI) and the Symptom Check List-90 (SCL-90). In order for us to determine whether the criteria for any of the conditions listed in the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) were met, the patients were asked to take part in the Structured Clinical Interview for DSM-IV disorders. RESULTS: Of the participants, 47.8% had a psychiatric disorder according to DSM-IV criteria, somatoform disorder (44.2%) being the most common. While 42.2% patients were determined to have a pathological finding using endoscopic evaluation, 57.8% had no findings. Together with the somatization and obsessive-compulsive disorder subscale scores, the total SCL-90 score and the mean trait anxiety score were statistically significantly higher in participants with no pathological findings. There were trends for anxiety (13.2% vs. 7.7%) and mood (2.6% vs. 0.0%) disorders to be more frequent in patients with pathological findings, while somatoform disorder+depressive disorder (17.3% vs. 5.2%) was more frequent in patients with no findings, although the differences were not statistically significant (Z=0.7, P>.05). The scores of state-trait anxiety, somatization, obsession-compulsion, depression, anxiety, phobic anxiety and psychotism subscales, and the total SCL-90 score were statistically significantly higher in those participants without a pathological finding than in the controls. CONCLUSIONS: Regarding the high frequency of psychiatric disorders in patients with dyspeptic symptoms, we think that such patients should be evaluated by two separate departments, gastroenterology and psychiatry.     

Characterization of depression in war-related posttraumatic stress disorder

OBJECTIVE: Many patients with posttraumatic stress disorder (PTSD) have symptoms of depression, but operationalized psychological constructs related to depression have not been used extensively in characterizing affective symptoms of PTSD. The authors' objective is to better characterize the affective component of PTSD. METHOD: The subjects were 45 male psychiatric inpatients at a Veterans Administration medical center; 28 met DSM-III-R criteria for PTSD and 17 met Research Diagnostic Criteria (RDC) for major depressive disorder. All of the subjects with PTSD were Vietnam veterans. The 21-item Hamilton Rating Scale for Depression was used to assess state measures of symptom severity, and the Depressive Experiences Questionnaire was used to measure dimensions of dependency, self-criticism, and self-efficacy. RESULTS: The mean total Hamilton scale score of the patients with PTSD was nonsignificantly higher than that of the patients with major depressive disorder; patients with PTSD had higher scores on almost all individual Hamilton symptoms, particularly insomnia, somatic anxiety, and diurnal variation. Patients with PTSD had significantly higher scores on the self-criticism scale but not on the dependency and self-efficacy scales of the Depressive Experiences Questionnaire. The scores of patients with PTSD on the dependency and self-criticism scales were negatively correlated. No significant differences between patients with PTSD with and without concurrent major depressive disorder were observed. CONCLUSIONS: Characterization of such depressive dimensions of PTSD as dependency and self-criticism may have important clinical implications.
