A blinded,controlled evaluation of anxiety and depressive symptoms in patients with fibromyalgia,as measured by standardized psychometric interview scales

The objective of the study was to evaluate the presence of psychopathology in fibromyalgia patients compared with a control group of other rheumatologic patients with pain. Forty-nine fibromyalgia patients and 33 control patients were interviewed blinded, using standardized psychometric scales. Pain was scored on a visual analogue scale. Fibromyalgia patients scored significantly higher than the controls on the Bech-Rafaelsen Melancholia Scale, the Atypical Depression Scale and the Hamilton Anxiety Rating Scale. On the Newcastle Depression Scale there was no difference. In both groups a correlation was found between pain score and psychometric scoring. The fibromyalgia patients scored significantly higher on pain than the controls. After correcting for this difference, the fibromyalgia patients still scored higher on anxiety and depression.     

A new self-rating scale for depression and anxiety states based on the Comprehensive Psychopathological Rating Scale

Self-assessment scales have long been used in psychiatric research even if their validity has often been questioned, one reason being poor the concordance of expert ratings. In clinical practice the use of rating scales is restricted, since they are considered to be time-consuming and perhaps even to disrupt the clinician's rapport with the patient. In the present study, a self-assessment scale, the CPRS Self-rating Scale for Affective Syndromes (CPRS-S-A), was constructed by re-phrasing in a self-rating format 19 items from the original Comprehensive Psychopathological Rating Scale (CPRS) and covering depression, anxiety and obsessional symptoms. In a group of 30 patients with depression syndromes and anxiety syndromes, the CPRS-S-A and the original CPRS were both used on 2 occasions. The patient's Global Assessment of Functioning scores ranged from 30 to 76 (mean 58), which suggests a moderate severity of illness, as does the fact that the majority were outpatients. There was a high degree of concordance between the instruments for most items and for the scores on the subscales for both diagnostic groups (i.e., the Montgomery-Åsberg Depression Rating Scale and the Brief Anxiety Scale, which are both subscales drawn from the CPRS). The time taken to complete the CPRS-S-A varied from 5 to 30 min (mean 19 min for depressive and 16 min for anxiety patients on the first occasion, 13 min for both groups on the second), and the self-rating procedure was readily accepted by both groups of patients. The CPRS-S-A would thus seem to be a promising instrument for quantitative rating of symptoms in ambulatory patients, both in clinical practice and in research.     

The monoclonal antibody Alz-50, used to reveal cytoskeletal changes in Alzheimer's disease, also reacts with a large subpopulation of somatostatin neurons in the normal human hypothalamus and adjoining areas

The monoclonal antibody Alz-50 is directed against Alzheimer's disease-related modified tau proteins and reveals cytoskeletal changes, i.e. neurofibrillary tangles and dystrophic neurites. The present study shows that, in the hypothalamus of non-demented control subjects, this same antibody gives a distinctive staining pattern of a subpopulation of somatostatin neurons and beaded fibers. Furthermore, Alz-50 occasionally recognizes somatostatin-containing cell bodies and dystrophic neurite-like fibers in the (neuritic) senile plaques of AD patients. These observations have direct consequences for the interpretation of Alz-50 staining in diagnostic usage and for the assessment of Alzheimer's disease-like changes induced by β-amyloid in experimental animal brains. On dot spotting, Alz-50 was found to bind to a number of fragments from the somatostatin precursor, of which somatostatin_15–28 stained best. Preadsorption of Alz-50 by somatostatin_15–28, as well as other specificity tests, failed, however, to provide any clue to the nature of the unknown compound(s) stained in the control hypothalamus.     

A Comparison of Depressive Symptoms in Stroke and Primary Care: Applying Rasch Models to Evaluate the Center for Epidemiologic Studies-Depression Scale

OBJECTIVES: Clinical trials and community-based studies often include the Center for Epidemiologic Studies-Depression scale (CES-D) as a measure of depression outcome. We compared responses to symptom-related items on the CES-D by depressed stroke and primary-care patients for several purposes: 1) to illustrate the use of Item Response Theory (IRT)-based (Rasch) models for comparing scale functioning across different patient subgroups; and 2) to inform clinicians and outcome researchers about scale functioning and depressive symptomatology in stroke- compared with primary care-based depression. METHODS: Two data sources were analyzed, including 32 depressed patients who were 3 months poststroke, and 366 depressed primary-care patients. Presence of depression was based on a CES-D score 16 or higher. Rasch models were used to assess item fit and compare item hierarchies between depressed primary-care and stroke patients. RESULTS: Item hierarchies were similar for poststroke depression and primary care-based depression. Interpersonal disruption items were the most difficult to endorse for both groups. No items misfit the scale in primary-care depression. Items relating to restless sleep, unfriendliness, and crying slightly misfit the scale in stroke patients, that is, may measure a different trait. Differential item functioning (DIF) between the groups was identified for items relating to appetite, restless sleep, crying, and feeling disliked. CONCLUSIONS: Results generally supported the use of the CES-D as measure of depression outcome, particularly in primary care-based depression. DIF may imply that slightly different clusters of depressive symptoms are reported by depressed stroke patients compared with primary care, but this is conjectural given the small stroke sample size and the same items have been previously associated with bias in studies of large nonstroke samples. This study found Rasch models to be useful tools to investigate scale performance for different clinical applications.

Factors associated with recovery and recurrence of depression in older people: A prospective study

The Liverpool Continuing Health in the Community Study has followed up 1070 elderly community subjects over 6 years. In the first year 123 subjects had case-level depression. Three years later 49 (39.8%) of the previously depressed were recovered, 33 (26.8%) were depressed, 16 (13%) were not available for interview and 25 (20.3%) were dead. This study looks at factors associated with the 3-year outcome of patients who were depressed at year 0. Two outcome groups that were compared were a recovered depression group and a recurrent/persistent depression group. The factors that were significantly associated with a recurrence of depression (or persistent depression) at year 3 were bereavement of a close figure in the 6 months before interview, loneliness and life dissatisfaction at year 3. A variety of traditional risk factors for depression (including age, marital status, physical ill-health and incapacity) failed to attain significance in predicting recurrent or persistent depression. When combined, both recovered and recurrently depressed groups at year 3 had significantly higher levels of pain and a higher number of serious upsets in the past 6 months and 6 weeks compared to a compared to a control group. The depressed at year 0 were more likely to have entered more dependent forms of accommodation by year 3.     

Do discrepancies in interpersonal perception predict relapse?: A comparison of remitted depressed patients and collaterals

In an effort to examine whether disturbed interpersonal relationships are associated with relapse in depression, discrepancies in self-ratings provided by formerly depressed patients and their collateral informants were compared. Thirty-eight remitted depressed patients and their collateral informants were asked to monitor moods, life events, and stress levels on a bimonthly basis for a 1-year period. It was hypothesized that patient/collateral dyads displaying a greater discrepancy in interpersonal perception would have a higher risk of relapse than dyads who showed more agreement in their ratings. Results indicated that while discrepancies in the perceptions of patients' life events were associated with the duration of a relapse once it occurred, discrepancies were generally not related to the emergence of new episodes of depressive disorder. The implications of these findings for models seeking to integrate cognitive and interpersonal models of depression, through the study of environmentally determined and personally appraised adversity, is discussed.This research was supported by grants to the first and third authors from the Canadian Psychiatric Research Foundation and the Laidlaw Foundation.
