The Diagnostic Inventory for Depression: a self-report scale to diagnose DSM-IV major depressive disorder

In this report from the Rhode Island Methods to Improve Diagnostic Assessment and Services (MIDAS) project, we describe the development and validation of the Diagnostic Inventory for Depression (DID), a new self-report scale designed to assess the Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV; American Psychiatric Association, 1994) symptom inclusion criteria for a major depressive episode, assess psychosocial impairment due to depression, and evaluate subjective quality of life. A large sample of 626 psychiatric outpatients completed the DID and were interviewed with the Structured Clinical Interview for DSM-IV (SCID). The measure's test-retest reliability, discriminant and convergent validity, and sensitivity to clinical change were investigated. The DID subscales achieved high levels of internal consistency and test-retest reliability. The DID was more highly correlated with another self-report measure of depression than with measures of anxiety, substance use problems, eating disorders, and somatization, thereby supporting the convergent and discriminant validity of the scale. The DID also was highly correlated with interviewer ratings of the severity of depression and psychosocial functioning, and DID symptom severity scores were significantly different in depressed patients with mild, moderate, and severe levels of depression. The DID was a valid measure of symptom change. Finally, the DID was significantly associated with a diagnosis of major depressive disorder.

Screening for bipolar disorders using a French version of the Mood Disorder Questionnaire (MDQ)

BACKGROUND: Bipolar disorders remain much too often unrecognized and subsequently inappropriately treated. This paper presents the translation into French and validation of the MDQ, a screening instrument for bipolar spectrum disorders, in an adult psychiatric sample. Modifications of its criteria for a positive screening as well as its test-retest reliability are also addressed. METHODS: A sample of 96 patients, attending outpatient treatment programs and suffering from mood disorders, completed the MDQ before being interviewed according to the mood module of the structured clinical interview for DSM-IV (SCID). They completed the MDQ a second time 1 month later, in order to examine its stability over time. RESULTS: According to the SCID interview, 54 patients were suffering from bipolar disorder and 42 from unipolar disorder. Among the bipolar sample, the MDQ identified 74.1% of them, with higher sensitivity in bipolar I (90.3%) than bipolar II (52.4%) and 90.5% specificity. Lowering the level of impairment required for positive screening led to improved sensitivity for bipolar II patients (76.2%). The French MDQ demonstrated adequate internal consistency (Cronbach alpha=0.89). Its test-retest reliability proved to be satisfactory, with a kappa coefficient of 0.79. Similar stability over a 1-month interval was obtained for bipolar type I and type II (kappa=0.75 and 0.77, respectively). LIMITATIONS: Similarly to the American version, the French MDQ has lower sensitivity for bipolar II disorders. CONCLUSIONS: The performance of the French MDQ is comparable to the one reported in the original American study conducted with a similar patient population. In a psychiatric outpatient sample, the French MDQ proves to be a feasible and reliable screening instrument.     

Differentiating Dissociative Disorders from Other Diagnostic Groups Through Somatoform Dissociation in Turkey

Abstract

This study aimed to assess the reliability, validity, and psychometric characteristics of the Turkish version of the Somatoform Dissociation Questionnaire (SDQ-20). In this context, it investigated whether somatoform dissociation differentiates dissociative disorders from other diagnostic groups and non-clinical individuals. The Turkish Version of the SDQ-20 was administered to 50 patients with a dissociative disorder, 94 patients with psychiatric disorders other than dissociative disorder, and 175 non-clinical participants. To confirm the clinical diagnosis, all patients in the dissociative disorder group had been evaluated using the Structured Clinical Interview for DSM-IV Dissociative Disorders. The internal consistency and the test-retest correlation of the SDQ-20 were excellent. The scale had strong correlations with the DES and the DIS-Q. There was a statistically significant difference between dissociative patients and other diagnostic groups on the SDQ-20 total score. The discriminative power of the SDQ-20 was as robust as that of the DES. There was no significant difference between the mean SDQ-20 total scores of Turkish and Dutch patients, but Turkish dissociative patients reported pseudoseizures more frequently than Dutch patients. The specificity of the short version of the scale (SDQ-5) was weak among Turkish patients. Dissociative disorders can be differentiated from other diagnostic groups through somatoform dissociation. The good psychometric characteristics of the SDQ-20 among Turkish participants support its cross-cultural validity.     

Validity of the patient health questionnaire (PHQ-9) as a screening tool for depression amongst Nigerian university students

BACKGROUND: The common self-rated depression scales are lengthy, old and do not reflect the current diagnostic classifications criteria of depressive disorders. This study aimed to validate the Patient Health Questionnaire (PHQ-9) as a screening tool for depression amongst Nigerian university students. METHODS: A representative sample of university students (n=512) completed the PHQ-9 and the Beck's Depressive Inventory (BDI). They were also interviewed for clinical diagnoses of depressive disorders using the Mini International Neuropsychiatric Interview (MINI). RESULTS: The internal consistency of questions within the PHQ-9 was 0.85. The PHQ-9 had good concurrent validity with the BDI (r=0.67, P<0.001). It also had a good (r=0.894, P<0.001) one month test-retest reliability. Using the Receiver Operating Characteristic (ROC) curve, the optimal cut-off score for minor depressive disorder is 5 (sensitivity 0.897, specificity 0.989, Positive Predictive Value - PPV 0.875, Negative Predictive Value - NPV 0.981 and Overall Correct Classification - OCC rate 0.973) while for major depressive disorder only is 10 (sensitivity 0.846, specificity 0.994, PPV 0.750, NPV 0.996 and OCC rate 0.992). LIMITATIONS: The study limitations include use of a specific group in community, moderate sample size and screening for only minor and major depressive disorders while neglecting other depressive disorders. CONCLUSIONS: The PHQ-9 has good psychometric properties amongst Nigerian university students. Because of its validity, reliability, brevity and ease of administration, the PHQ-9 will be a valuable tool for estimating depression amongst college students in Nigerian community. More studies are needed to test the usefulness of the translated local language versions of this instrument amongst the community in sub-Saharan Africa.

The postpartum depression screening scale: is it valid to screen for antenatal depression?

The purpose of the study was to analyse for the first time the validity of a slightly modified version of the Portuguese Postpartum Depression Screening Scale (PDSS), to be used as a screening instrument for antenatal depression. Specifically, the aims were to analyse its psychometric properties, to determine PDSS cutoff points and associated conditional probabilities to screen for depression according to DSM-IV and ICD-10 criteria and to compare its screening performance with that of the Beck Depression Inventory-II (BDI-II). Five hundred and three pregnant women in the third trimester of pregnancy completed both questionnaires and were interviewed face-to-face with the Portuguese version of the Diagnostic Interview for Genetic Studies. The Portuguese version of the Operational Criteria Checklist for Psychotic Illness was used to obtain DSM-IV and ICD-10 diagnoses of depression, our gold standards for caseness. PDSS reliability and validity were very good and comparable to those obtained in the postpartum validation studies developed in Portugal and in other countries, showing satisfactory sensitivity and specificity combinations (≅80%). Compared with BDI-II, it has the advantage of being more specific for the motherhood context. Although developed for postpartum depression, PDSS is accurate to screen for antenatal depression, and it could be very useful for clinical and epidemiologic purposes.
