Lifetime and 12-month prevalence of Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition disorders among older African Americans: findings from the National Survey of American Life.

OBJECTIVE: The purpose of this study was to estimate lifetime and 12-month prevalence of 13 psychiatric disorders for older African Americans. METHODS: Data are from the older African American subsample of the National Survey of American Life. Selected measures of lifetime and 12-month Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) psychiatric disorders were examined (i.e., panic disorder, agoraphobia, social phobia, generalized anxiety disorder, obsessive compulsive disorder, posttraumatic stress disorder (PTSD), major depressive disorder, dysthymia, bipolar I and II disorders, alcohol abuse/dependence, and drug abuse/dependence). RESULTS: Twenty-three percent of older African Americans reported at least one lifetime disorder and 8.54% reported at least one 12-month disorder. Alcohol abuse, PTSD, and major depression were the most prevalent lifetime disorders. The most prevalent 12-month disorders were PTSD, major depression, and social phobia. Age, sex, education, and region were significantly associated with the odds of having a lifetime disorder. CONCLUSION: This is the first study of prevalence rates of serious mental disorders for older African Americans based on a national sample. Demographic correlates of the prevalence of disorders are discussed with an emphasis on age and regional differences.     

Twelve-month and lifetime prevalence and lifetime morbid risk of anxiety and mood disorders in the United States

Estimates of 12‐month and lifetime prevalence and of lifetime morbid risk (LMR) of the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM‐IV‐TR) anxiety and mood disorders are presented based on US epidemiological surveys among people aged 13+. The presentation is designed for use in the upcoming DSM‐5 manual to provide more coherent estimates than would otherwise be available. Prevalence estimates are presented for the age groups proposed by DSM‐5 workgroups as the most useful to consider for policy planning purposes. The LMR/12‐month prevalence estimates ranked by frequency are as follows: major depressive episode: 29.9%/8.6%; specific phobia: 18.4/12.1%; social phobia: 13.0/7.4%; post‐traumatic stress disorder: 10.1/3.7%; generalized anxiety disorder: 9.0/2.0%; separation anxiety disorder: 8.7/1.2%; panic disorder: 6.8%/2.4%; bipolar disorder: 4.1/1.8%; agoraphobia: 3.7/1.7%; obsessive‐compulsive disorder: 2.7/1.2. Four broad patterns of results are most noteworthy: first, that the most common (lifetime prevalence/morbid risk) lifetime anxiety‐mood disorders in the United States are major depression (16.6/29.9%), specific phobia (15.6/18.4%), and social phobia (10.7/13.0%) and the least common are agoraphobia (2.5/3.7%) and obsessive‐compulsive disorder (2.3/2.7%); second, that the anxiety‐mood disorders with the earlier median ages‐of‐onset are phobias and separation anxiety disorder (ages 15–17) and those with the latest are panic disorder, major depression, and generalized anxiety disorder (ages 23–30); third, that LMR is considerably higher than lifetime prevalence for most anxiety‐mood disorders, although the magnitude of this difference is much higher for disorders with later than earlier ages‐of‐onset; and fourth, that the ratio of 12‐month to lifetime prevalence, roughly characterizing persistence, varies meaningfully in ways consistent with independent evidence about differential persistence of these disorders.

Panic Disorder and Agoraphobia in OCD patients: Clinical profile and possible treatment implications

Objective

Panic Disorder (PD) and agoraphobia (AG) are frequently comorbid with obsessive–compulsive disorder (OCD), but the correlates of these comorbidities in OCD are fairly unknown. The study aims were to: 1) estimate the prevalence of PD with or without AG (PD), AG without panic (AG) and PD and/or AG (PD/AG) in a large clinical sample of OCD patients and 2) compare the characteristics of individuals with and without these comorbid conditions.

Method

A cross-sectional study with 1001 patients of the Brazilian Research Consortium on Obsessive–Compulsive Spectrum Disorders using several assessment instruments, including the Dimensional Yale–Brown Obsessive–Compulsive Scale and the Structured Clinical Interview for DSM-IV-TR Axis I Disorders. Bivariate analyses were followed by logistic regression models.

Results

The lifetime prevalence of PD was 15.3% (N = 153), of AG 4.9% (N = 49), and of PD/AG 20.2% (N = 202). After logistic regression, hypochondriasis and specific phobia were common correlates of the three study groups. PD comorbidity was also associated with higher levels of anxiety, having children, major depression, bipolar I, generalized anxiety and posttraumatic stress disorders. Other independent correlates of AG were: dysthymia, bipolar II disorder, social phobia, impulsive–compulsive internet use, bulimia nervosa and binge eating disorder. Patients with PD/AG were also more likely to be married and to present high anxiety, separation anxiety disorder, major depression, impulsive–compulsive internet use, generalized anxiety, posttraumatic stress and binge eating disorders.

Conclusions

Some distinct correlates were obtained for PD and AG in OCD patients, indicating the need for more specific and tailored treatment strategies for individuals with each of these clinical profiles.     

Comorbidity in bipolar disorder among the elderly: results from an epidemiological community sample

OBJECTIVE: This study sought to determine psychiatric comorbidity among elderly individuals with bipolar disorder. METHOD: An epidemiological community survey identified 84 elderly (ages >/=65) respondents with bipolar disorder, 1,327 younger adults with bipolar disorder, and 8,121 elderly respondents without bipolar disorder. RESULTS: Elderly respondents with bipolar disorder reported lifetime and 12-month rates of comorbid alcohol use disorders (38.1%, 38.1%, respectively), dysthymia (15.5%, 7.1%), generalized anxiety disorder (20.5%, 9.5%), and panic disorder (19.0%, 11.9%) that were significantly higher than among elderly respondents without bipolar disorder. They had lower lifetime and 12-month rates of alcohol use disorders and lower 12-month rates of dysthymia and panic disorder than younger adults with bipolar disorder. Elderly men with bipolar disorder reported a greater prevalence of alcoholism; women reported a greater prevalence of panic disorder. CONCLUSIONS: Comorbid axis I disorders, including panic disorder, are common among elderly individuals with bipolar disorder.     

Lifetime prevalence of psychiatric disorders in patients with alopecia areata

Thirty-one patients with alopecia areata were administered a structured psychiatric interview (the Diagnostic Interview Schedule; DIS). Overall, 74% had one or more lifetime psychiatric diagnoses. Particularly noteworthy were the high lifetime prevalence rates of major depression (39%) and generalized anxiety disorder (39%). In addition, patients reported increased rates of psychiatric disorders in first-degree relatives: anxiety disorders (58%), affective disorders (35%), and substance use disorders (35%). Patients with patchy alopecia areata were more likely to have a diagnosis of generalized anxiety disorder. No relationships were found between major depression and any variable characterizing alopecia areata history. Possible interrelationships between psychiatric disorders and alopecia areata are discussed. The study suggests that patients with alopecia areata are at increased risk for psychiatric disorders, and calls attention to the need for psychiatric assessment in this population.     

Internalizing disorder in adopted versus non-adopted adults: A NESARC based study

The objective of the study consisted of comparing lifetime prevalence rates and odds ratios of anxiety, mood, and psychotic disorders in adopted-versus-non-adopted people in a nationally representative sample. The data were drawn from the National Epidemiological Survey on Alcohol and Related Conditions (NESARC). The main outcome measure was the prevalence of lifetime internalizing psychiatric disorders in adopted (n = 378) versus non-adopted (n = 42,503) individuals. Adoptees and non-adoptees were compared to estimate the odds of lifetime internalizing disorders using logistic regression analyses. Adoptees had higher prevalence rates of several lifetime mood and anxiety disorders compared with non-adoptees, with a 1.61-fold increase (95% CI 1.29–2.02) in the odds of any mood disorder and a 1.49-fold increase (95% CI 1.18–1.89) in the odds of any anxiety disorder compared with non-adoptees. Regarding specific mood and anxiety disorders, adoptees had increased odds of major depressive disorder, bipolar I disorder, panic disorder without agoraphobia, specific phobia, and generalized anxiety disorder. Disorders not differing between adoptees and non-adoptees included dysthymia, bipolar II disorder, panic disorder with agoraphobia, social phobia, and psychotic disorder. One adoption-specific risk factor was associated with lifetime mood disorder (i.e., Asian/Pacific Island). In conclusion, adoptees in a large sample from the general population had higher rates of mood and anxiety disorders compared to non-adoptees.     

Anxiety disorders in major depression

The prevalence and clinical impact of anxiety disorder comorbidity in major depression were studied in 255 depressed adult outpatients consecutively enrolled in our Depression Research Program. Comorbid anxiety disorder diagnoses were present in 50.6% of these patients and included social phobia (27.0%), simple phobia (16.9%), panic disorder (14.5%), generalized anxiety disorder ([GAD] 10.6%), obsessive-compulsive disorder ([OCD] 6.3%), and agoraphobia (5.5%). While both social phobia and generalized anxiety preceded the first episode of major depression in 65% and 63% of cases, respectively, panic disorder (21.6%) and agoraphobia (14.3%) were much less likely to precede the first episode of major depression than to emerge subsequently. Although comorbid groups were not distinguished by depression, anxiety, hostility, or somatic symptom scores at the time of study presentation, patients with comorbid anxiety disorders tended to be younger during the index episode and to have an earlier onset of the major depressive disorder (MDD) than patients with major depression alone. Our results support the distinction between anxiety symptoms secondary to depression and anxiety disorders comorbid with major depression, and provide further evidence for different temporal relationships with major depression among the several comorbid anxiety disorders.     

Parkinson's disease: a preliminary study of yohimbine challenge in patients with anxiety.

In this pilot study, we performed an oral yohimbine challenge in 6 patients with Parkinson's disease (PD) and anxiety or depression, 2 parkinsonian patients without psychiatric illness, and 2 healthy control subjects to determine whether patients with Parkinson's disease and anxiety respond to this adrenergic agent in the same way patients with idiopathic anxiety disorders respond. Given the atypical nature of depression in Parkinson's disease (characterized by prominent anxiety), we also wanted to see if patients with Parkinson's disease and depression (but no history of anxiety) are susceptible to yohimbine-induced panic. Parkinsonian patients with anxiety developed panic attacks at frequencies comparable to primary psychiatric patients with panic disorder. The one patient with PD and a history of major depression alone developed a panic attack. Regardless of their history of anxiety or depression, parkinsonian patients demonstrated a vulnerability to yohimbine-induced somatic symptoms.     

Relation between depression and anxiety in dystonic patients: implications for clinical management

Past clinical research has identified depression as the most common psychiatric disorder associated with cervical dystonia (CD). The purpose of our study is to document different patterns of psychopathology, the frequency of psychiatric disorders, and possible correlation with the neurological disorder in patients with CD. Forty patients with CD were investigated to assess levels of psychopathology on two self-rated scales: the Beck Depression Inventory (BDI) and Symptom Check List (SCL-90). To determine the presence of psychiatric disorders, the patients were evaluated using the standard instrument in the DSM-III-R (Structured Clinical Interview Schedule, SCID). A small group of dystonic patients (12%) had higher levels of psychopathology, with significant amounts of concomitant anxiety and depression on the BDI and SCL-90. SCID criteria for at least one psychiatric disorder were fulfilled in 22 patients (55%), including both the lifetime and current diagnoses. The most frequent diagnostic categories were anxiety (40%) and major depressive disorders (37.5%). In 17 patients (42.5%), criteria for at least one lifetime diagnosis were fulfilled prior to the onset of CD. Psychiatric evaluation does not indicate one specific disorder associated with CD. The presence of anxiety and depression symptoms before and during the course of dystonia, without a possible causal relationship, could mean that the alteration of a chain of physiological events in the central nervous system may not lead to a single clinical picture. The relatively high overall lifetime prevalence of anxiety and depressive disorders may indicate the need for a broader diagnostic and therapeutic approach to patients with focal dystonia.     

The effect of somatic symptom attribution on the prevalence rate of depression and anxiety among nursing home patients

The validity of diagnostic psychiatric instruments for depression and anxiety disorders may be compromised among patients with complex physical illness and disability. The objective of this study was to determine the effect on the prevalence rate of depression and anxiety in a nursing home population of attributing somatic symptoms of depression and anxiety to either somatic or psychiatric disorder. Symptoms of major depression (MD), generalized anxiety disorder (GAD) and panic disorder (PD) were measured using the Schedules for Clinical Assessment in Neuropsychiatry (SCAN). Somatic symptoms of MD, GAD and PD were attributed to somatic causes when the interviewer was not sure about a psychiatric cause. To analyse the effect of this attribution on the prevalence rate of MD, GAD and PD, a sensitivity analysis was undertaken in which symptoms that were attributed to somatic causes were recoded as symptoms attributed to psychiatric disorder. Prevalence rates of MD, GAD and PD were calculated before and after recoding. The prevalence of MD after recoding rose from 7.5% to 8.1%. The prevalence of GAD did not change. The prevalence of PD rose from 1.5% to 1.8%. Attribution of somatic symptoms to either somatic or psychiatric disorder when the interviewer was not sure about a psychiatric cause of the somatic symptoms had only a very modest effect on the prevalence rate of major depression, generalized anxiety disorder and panic disorder in a nursing home population.     

The comorbidity of anxiety disorders in bipolar I patients: prevalence and clinical correlates

The purpose of this study was to determine the prevalence of lifetime anxiety disorders in bipolar I patients in Sanliurfa, Turkey, and to assess the association between comorbidity and several demographic and clinical variables. Seventy bipolar I patients in remission were assessed by means of the Structured Clinical Interview for DSM-IV axis I Disorders-Clinician Version (SCID-I-CV), Anxiety Disorder Module in order to detect lifetime comorbid anxiety disorders. Nineteen (27.1%) bipolar I patients were diagnosed with at least one lifetime comorbid anxiety disorder. The most common anxiety disorders in this sample were obsessive compulsive disorder (12.8%) and specific phobia (12.8%), followed by panic disorder (5.7%). Anxiety disorder comorbidity appears to be associated with greater number of hospitalizations, psychotic symptoms and suicide attempts in patients with bipolar I disorder. As comorbidity has a clear impact on the course of bipolar patients, special attention to this issue should be paid when interviewing bipolar patients.     

Psychopathology in the offspring of parents with bipolar disorder: a controlled study.

BACKGROUND: To examine the risk for psychopathology in offspring at risk for bipolar disorder and the course of psychiatric disorders in these youth. METHODS: Using structured diagnostic interviews (Structured Clinical Interview for DSM-IV [SCID] and Kiddie Schedule for Affective Disorders and Schizophrenia [K-SADS]), psychiatric diagnoses of 117 nonreferred offspring of parents with diagnosed bipolar disorder were compared with those of 171 age- and gender-matched offspring of parents without bipolar disorder or major depression. RESULTS: Compared with offspring of parents without mood disorders, high-risk youth had elevated rates of major depression and bipolar disorder, anxiety, and disruptive behavior disorders. High-risk offspring also had significantly more impaired Global Assessment of Functioning (GAF) scores, higher rates of psychiatric treatment, and higher rates of placement in special education classes. Disruptive behavior disorders, separation anxiety disorder, generalized anxiety disorder (GAD), social phobia, and depression tended to have their onset in early or middle childhood, whereas bipolar disorder, obsessive-compulsive disorder (OCD), panic disorder, and substance use disorder had onset most frequently in adolescence. CONCLUSIONS: These findings support the hypothesis that offspring of parents with bipolar disorder are at significantly increased risk for developing a wide range of severe psychiatric disorders and accompanying dysfunction. Early disruptive behavior and anxiety disorders, as well as early-onset depression, may be useful markers of risk for subsequent bipolar disorder in high-risk samples.     

Lifetime and 12-month prevalence of DSM-IV psychiatric disorders among Korean adults

The objective was to estimate the prevalence and correlates of psychiatric disorders in a nationwide sample of Korean adults. Face-to-face interviews were conducted with the Korean version of Composite International Diagnostic Interview 2.1/DSM-IV (N = 6275, response rate 79.8%). The lifetime and 12-month prevalences for all types of DSM-IV disorders were 33.5% and 20.6%, respectively. Those of specific disorders were as follows: 17.2% and 7.1% for alcohol use disorder, 11.2% and 7.4% for nicotine use disorder, 5.2% and 4.2% for specific phobia, 4.3% and 1.7% for major depressive disorder, and 2.3% and 1.0% for generalized anxiety disorder. Among the sociodemographic variables, widowed status, higher income, and rural residence were the risk factors for both lifetime major depressive disorder and alcohol use disorder after controlling for gender, age, and education. The prevalence of psychiatric disorders was higher than those observed in other East-Asian countries and most European countries, but lower than that in the United States. Alcohol use disorder was particularly high in Korea.     

Atypical depression in Japan--39 case series]

In Japan, relatively little attention has been paid to atypical depression, which is defined as the presence of mood reactivity and two of four associated features: hyperphagia, hypersomnia, leaden paralysis, rejection sensitivity. The present study was undertaken to obtain detailed clinical information from patients with a diagnosis of atypical depression. We assessed clinical characteristics of each atypical feature, comorbidity of other psychiatric disorders, presence of a stressful life event, and underlying psychological stress in 39 psychiatric outpatients. We also examined the relationship of interpersonal sensitivity to each atypical feature. RESULTS AND DISCUSSION: Mean age of onset was 22 +/- 6, 74% were female, 20 patients (51%) had comorbid social phobia. Thirty (77%) had hyperphagia and 25 of these were women. Twenty (74%) had hypersomnia. Only seven patients reported daytime sleepiness and others (13) reported difficulty in staying awake due to lack of energy. Nineteen (49%) had leaden paralysis. Thirty-two patients (82%) had rejection sensitivity and this symptom correlated with scores of FNE (fears of negative evaluation), LSAS (Liebowits social anxiety scale) and Brief social phobia scale (BSPA). Seven patients reported disappointment in love as a stressful life event preceding the depressive episode. In patients with comorbid social phobia, loss of confidence due to hypersensitivity to rejection or criticism seemed to be the most important factor as a chronic psychologica stress. Seven patients met criteria for bipolar disorder and five out of seven had comorbid generalized social phobia. The clinical and theoretical implications of these findings were discussed.     

Comorbid anxiety disorders in depressed elderly patients

OBJECTIVE: Anxiety disorders are common in adults with depressive disorders, but several studies have suggested a relatively low prevalence of anxiety disorders in older individuals with depression. This cross-sectional study measured current and lifetime rates and associated clinical features of anxiety disorders in depressed elderly patients. METHOD: History of anxiety disorders was assessed by using a structured diagnostic instrument in 182 depressed subjects aged 60 and older seen in primary care and psychiatric settings. Associations between comorbid anxiety disorders and baseline characteristics were measured. The modified structured instrument allowed detection of symptoms that met inclusion criteria for generalized anxiety disorder in a depressive episode. RESULTS: Thirty-five percent of older subjects with depressive disorders had at least one lifetime anxiety disorder diagnosis, and 23% had a current diagnosis. The most common current comorbid anxiety disorders were panic disorder (9.3%), specific phobias (8.8%), and social phobia (6.6%). Symptoms that met inclusion criteria for generalized anxiety disorder, measured separately, were present in 27.5% of depressed subjects. Presence of a comorbid anxiety disorder was associated with poorer social function and a higher level of somatic symptoms. Symptoms of generalized anxiety disorder were associated with a higher level of suicidality. CONCLUSIONS: Contrary to previous reports, the present study found a relatively high rate of current and lifetime anxiety disorders in elderly depressed individuals. Comorbid anxiety disorders and symptoms of generalized anxiety disorder were associated with a more severe presentation of depressive illness in elderly subjects.     

Anxiety disorders in 318 bipolar patients: prevalence and impact on illness severity and response to mood stabilizer

OBJECTIVE: The aim of this study was to assess the frequency and impact of anxiety disorders on illness severity and response to mood stabilizers in bipolar disorders. METHOD: 318 bipolar patients consecutively admitted to the psychiatric wards of 2 centers as inpatients were recruited. Patients were interviewed with a French version of the Diagnostic Interview for Genetic Studies providing DSM-IV Axis I diagnoses and demographic and historical illness characteristics. Logistic and linear regressions to adjust for age and sex were performed. RESULTS: In a population with mostly bipolar type I patients (75%), 24% had at least 1 lifetime anxiety disorder (47% of these patients had more than 1 such disorder), 16% of patients had panic disorder (with and without agoraphobia, and panic attacks), 11% had phobia (agoraphobia without panic disorder, social phobia, and other specific phobias), and 3% had obsessive-compulsive disorder. Comorbidity with anxiety disorders was not correlated with severity of bipolar illness as assessed by the number of hospitalizations, psychotic characteristics, misuse of alcohol and drugs, and suicide attempts (violent and nonviolent). Bipolar patients with an early onset of illness had more comorbidity with panic disorder (p <.05). Anxiety disorders were detected more frequently in bipolar II patients than in other patients, but this difference was not significant (p =.09). Bipolar patients with anxiety responded less well to anticonvulsant drugs than did bipolar subjects without anxiety disorder (p <.05), whereas the efficacy of lithium was similar in the 2 groups. There was also a strong correlation between comorbid anxiety disorders and depressive temperament in bipolar patients (p =.004). CONCLUSION: Patients with bipolar disorders often have comorbid anxiety disorders, particularly patients with depressive temperament, and the level of comorbidity seems to decrease the response to anticonvulsant drugs.     

The prevalence of atypical features across mood,anxiety, and personality disorders

This study examines and compares the prevalence rates of the atypical features subtype across each of the major mood, anxiety, and personality disorders (PDs). It also evaluates the impact that comorbid anxiety and PDs have on the likelihood that depressed patients will present with atypical symptoms. Eleven hundred thirty psychiatric outpatients were evaluated for the presence of atypical symptoms. All axis I diagnoses were made using the Structured Clinical Interview for DSM-IV (SCID). PDs were assessed in a subset of 530 patients using the Structured Interview for DSM-IV Personality Disorders (SIDP-IV). From a sample of 579 patients diagnosed with a current major depressive disorder, 22.5% met criteria for the atypical subtype. Prevalence rates were similar in bipolar and unipolar patients, although the pattern of symptoms was distinct. Prevalence rates were lower in patients with dysthymic disorder (12.5%), adjustment disorder with depressed mood (9.4%), and depression not otherwise specified (NOS) (7.9%). When major depression existed in the presence of a comorbid anxiety disorder, the likelihood of presenting with atypical features doubled. Nine percent of the patients diagnosed with an anxiety disorder (without a comorbid depressive disorder) met criteria for atypical features. Two of the four atypical symptoms, leaden paralysis and rejection sensitivity, were found to be especially prominent in nondepressed anxiety disorder patients. Of the 10 PDs listed in DSM-IV, only avoidant PD was associated with the atypical features subtype. In large part, this was accounted for by the high rate of rejection sensitivity in these patients. In conclusion, as many as one quarter of depressed patients who present for outpatient psychiatric treatment meet criteria for the atypical features subtype. There appears to be a strong association between anxiety and atypical depression, but the exact nature of this relationship needs to be further elucidated. It is unclear whether personality pathology is independently associated with the atypical features subtype.     

Comorbidity of anxiety disorder among patients with bipolar I disorder in remission

The aim of this study was to assess the comorbidity of lifetime and current prevalences of anxiety disorders among 70 patients with bipolar I disorder in remission using structured diagnostic interviews and to examine the association between comorbidity and several demographic and clinical variables. Forty-three (61.4%) bipolar I patients also met DSM-IV criteria for at least one lifetime comorbid anxiety disorder. Obsessive-compulsive disorder (39%) was the most common comorbid lifetime anxiety disorder, followed by simple phobia (26%) and social phobia (20%). First episode and male sex were found to have lower rates of comorbid current anxiety disorders. The presence of anxiety disorders was related to significantly higher scores on both anxiety and general psychopathology scales. The results of the present study support previous findings of a high comorbidity rate of anxiety disorders in bipolar I disorder cases and indicate that the presence of an anxiety disorder leads to more severe psychopathology levels in bipolar I patients.     

Change in prevalence of psychiatric disorders from ages 21 to 30 in a community sample

The authors examined change and demonstrated variation in the prevalence of psychiatric disorders from ages 21 to 30 in a prospective community study (n = 352) using generalized estimating equations and investigated effects of past and recent psychiatric disorder on emerging adult functioning (at age 30). Results revealed significant declines in 12-month prevalence of phobia and substance use disorders from ages 21 to 30 but not in depression or posttraumatic stress disorder. Males were at significantly higher risk for lifetime substance use disorders; females were at higher risk for lifetime depression, phobia, and PTSD. Twelve-month and lifetime disorder were associated with impaired global functioning at age 30. Internalizing disorders were associated with impaired interpersonal functioning, whereas externalizing disorders were associated with impaired socioeconomic functioning. Results of this study have implications for mental health service planning in emerging adulthood.     

Screening of psychiatric disorders via the Internet. A pilot study with tinnitus patients

Tinnitus has been associated with psychiatric disorders and more recently diagnostic tools have been used in a systematic manner. In the present study, we administered the World Health Organisation's Composite International Diagnostic Interview--Short form (CIDI-SF) in a computerized Internet-based version to a self-selected sample of tinnitus patients (n=48). Using the cut-off for 'probable case' (12-month prevalence), 69% of the tinnitus patients fulfilled the criteria for depression, 60% for generalized anxiety disorder, 83% for specific phobia, 67% for social phobia, 58% for agoraphobia, 21% panic attack, 83% obsessive-compulsive disorder, 2% alcohol dependence and 0% drug dependence. Decreased percentages were found for depression (4%), specific phobia (62%) and social phobia (27%) when applying a more conservative criteria (maximum case criteria). In conclusion, the findings suggest that the Internet version of CIDI-SF can be used as a screening tool for psychiatric disturbance in somatic patients, but that diagnostic criteria need to be adjusted for Internet use.
