Objective: The Biological Rhythms Interview of Assessment in Neuropsychiatry (BRIAN) is a tool aimed at clinically evaluating disturbances in biological rhythm. In this study, we examined the reliability and validity of the Macedonian version of the BRIAN. Methods: A total of 100 participants, including 50 subjects with bipolar disorder (BD) and 50 control healthy subjects, were recruited. Construct validity was tested by comparing the mean BRIAN scores of the BD patients and control subjects. Results: No difference by gender or age was noticed, but patients differed from controls in education and occupation. Reliability, as measured with Cronbach’s alpha, was good in BD individuals, except for the Rhythms subscale. Reliability in controls was less good, especially for the Sleep and Rhythms subscales. The tool was able to discriminate patients with controls, with large differences on all subscales. However, since the reliability was suboptimal for some of these subscales, these diff...
Biological rhythm disturbance in remitted bipolar patients
International Journal of Bipolar Disorders, 2013
Background Biological rhythm disturbance is common in bipolar patients and seems to affect the course and prognosis of the illness negatively. The main aim of the current study was to assess biological rhythms in remitted bipolar patients. We also assessed whether there was an association between clinical variables or functioning and biological rhythms in remitted bipolar participants. Methods The Biological Rhythms Interview of Assessment in Neuropsychiatry (BRIAN) was used to assess biological rhythm disturbance. It is an 18-item interviewer-administered instrument which allows us to investigate the main areas related to circadian rhythm disturbance (sleep/social, activities, and eating pattern) in bipolar disorder. Results and discussion Bipolar patients (n = 107) experienced greater biological rhythm alterations than the control group (n = 100) (BRIAN total scores 35.36 ± 7.11 vs. 32.48 ± 6.10, t = 6.912, p = 0.002, Cohen's d = 0.43, r = 0.21). In particular, patients were m...

Objective: To assess the relationship of biological rhythms, evaluated by the Biological Rhythms Interview of Assessment in Neuropsychiatry (BRIAN), with affective temperaments and schizotypy. Methods: The BRIAN assessment, along with the Temperament Evaluation of Memphis, Pisa, Paris, and San Diego-Autoquestionnaire (TEMPS-A) and the Oxford-Liverpool Inventory for Feelings and Experiences (O-LIFE), was administered to 54 patients with remitted bipolar disorder (BD) and 54 healthy control (HC) subjects. Results: The TEMPS-A cyclothymic temperament correlated positively and the hyperthymic temperament correlated negatively with BRIAN scores in both the BD and HC groups, although the correlation was stronger in BD subjects. Depressive temperament was associated with BRIAN scores in BD but not in HC; conversely, the irritable temperament was associated with BRIAN scores in HC, but not in BD. Several positive correlations between BRIAN scores and the schizotypal dimensions of the O-LIFE were observed in both BD and HC subjects, especially with cognitive disorganization and less so with unusual experiences and impulsive nonconformity. A correlation with introversion/ anhedonia was found only in BD subjects. Conclusion: Cyclothymic and depressive temperaments predispose to disturbances of biological rhythms in BD, while a hyperthymic temperament can be protective. Similar predispositions were also found for all schizotypal dimensions, mostly for cognitive disorganization.
Functional impact of biological rhythm disturbance in bipolar disorder
Journal of Psychiatric Research, 2010
a b s t r a c t Bipolar disorder (BD) is characterized by frequent recurrence, incomplete recovery, cognitive dysfunction and poor functioning. Impairment lingers in the interepisodic period and mechanisms leading to this dysfunctional state are not fully comprehended. To our knowledge the association of biological rhythm dysfunction with functioning in BD has not been assessed directly. The objective of this study was to measure and quantify the impact of rhythm dysfunction on interepisodic functioning in BD. We also tested the association between executive functioning and sleep and rhythm problems. Eighty-one outpatients with BD and 79 matched control subjects were consecutively recruited. Functional impairment was assessed with the Functioning Assessment Short Test (FAST) and biological rhythms with the Biological Rhythms Interview of Assessment in Neuropsychiatry (BRIAN). A subsample had their executive functioning assessed with the Wisconsin Card Sorting Test (WCST). Patients and control subjects were well matched. Functioning and rhythm scores were correlated in patients and control subjects. The BRIAN score was the strongest predictor of functioning in the regression model. Biological rhythms partially mediated the impairment associated with bipolar disorder. The rhythm score was also associated with executive functioning. Biological rhythm dysfunction was a potent predictor of functioning in interepisodic patients with bipolar disorder; it may also mediate much of the disorder-induced disability. These results further the notion that biological rhythms may be interesting targets for diverse interventions aiming to improve functioning and prevent relapse in interepisodic bipolar disorder.

Circadian rhythm disturbances have been associated with bipolar disorder (BD) during both the mood episodes and the periods of remission. Circadian phase preferences for the evening have been reported for remitted patients, whereas the amplitude and stability of their rhythms have never been assessed using questionnaires. The primary aim of our study was the validation of a French version of the Circadian Type Inventory (CTI), whereas its secondary aim was the comparison between remitted patients with BD and healthy controls for rhythm stability and amplitude and for phase preference. For this purpose, we used the CTI and the Composite Scale of Morningness (CSM) that assesses phase preference (''morning'' or ''evening'' type). First, we report here on the validation of the French version of the 11-item Circadian Type Inventory in a sample of 140 remitted patients with BD and 156 healthy controls. Principal components analysis revealed a two-factor structure (FR: flexibility/rigidity scale corresponding to rhythm stability; LV: languid/vigorous scale corresponding to rhythm amplitude) explaining 52% of the variance in the control group and 47% in the bipolar group. Cronbach's alpha was 0.75 for FR and 0.73 for LV. The test-retest reliability was 0.74 for FR and 0.86 for LV (3 wks) and 0.62 for FR and 0.72 for LV (6 mos). LV and FR scores correlated with the Composite Scale of Morningness score (p50.00001 and p ¼ 0.0002, respectively). Second, as compared with controls, patients with BD were more languid (p50.00001) and showed an evening preference (p ¼ 0.0003), but they did not differ from the controls with regard to flexibility/rigidity. The French version of the CTI appeared to have satisfactory psychometrics characteristics. Bipolar patients exhibited not only abnormalities in phase preference but also in amplitude as measured by languidity. Since circadian rhythm dysfunction has been shown to predict poor functioning and mood relapses in interepisodic patients with BD, this tool would appear to be a promising, easy-to-use, measure of the amplitude and flexibility of circadian rhythms that could enrich the arsenal of assessments used in clinical settings.

BackgroundInterest in biological clock pathways in bipolar disorders (BD) continues to grow, but there has yet to be an audit of circadian measurement tools for use in BD research and practice.ProcedureThe International Society for Bipolar Disorders Chronobiology Task Force conducted a critical integrative review of circadian methods that have real‐world applicability. Consensus discussion led to the selection of three domains to review—melatonin assessment, actigraphy, and self‐report.ResultsMeasurement approaches used to quantify circadian function in BD are described in sufficient detail for researchers and clinicians to make pragmatic decisions about their use. A novel integration of the measurement literature is offered in the form of a provisional taxonomy distinguishing between circadian measures (the instruments and methods used to quantify circadian function, such as dim light melatonin onset) and circadian constructs (the biobehavioral processes to be measured, such as cir...

Alterations in specific structures of CNS, in particular, fronto-lymbic system, and a reduction of neurons and glial cells appear to be involved in the pathophysiology of bipolar disorder. Glial cells have an important role in the CNS, for example, the production of neurotrophins, especially, Glial Cell Line-derived Neurotrophic Factor (GDNF). In this study, we showed a marked increased in the serum levels of GDNF in depressive (F= 42.31; p=0.004; one-way ANOVA) and manic bipolar patients (F= 42.31; p=0.001; one-way ANOVA), which suggested that GDNF could be involved in the physiopathology of bipolar disorder. On the other hand, alterations in the neurotrophic factors hinder synaptic plasticity mechanisms, may result in cognitive impairment in bipolar patients. In particular, memory difficulties have been reported here, and these difficulties influence occupational and social functioning in these subjects. High rates of functional impairment showed by bipolar patients and a lack of standardization of the instruments available to assess functioning in the studies motivated us to development the scale. The Functioning Assessment Short test (FAST) is a rapid instrument and easy to apply developed to use in psychiatry, especially, bipolar patients. It assesses six specific domains of functioning, such as autonomy, occupational functioning, cognitive functioning, financial issues and leisure time. The validation of FAST was performed by psychometric tests such as internal consistency (Cronbach's alpha: 0.909), concurrent validity compared to the GAF (r=-0.903; p<0.001), validity as a discriminative measure to detect the difference between euthymic (18.55; F=23.59; p<0.001) and acute patients (manic: 38.50; depressive: 42.38; mixed: 43.21), factorial analysis and test-retest reliability (0.953; p<0.01). The FAST scale showed strong psychometric properties and it is now available for use in both clinical practice and investigation settings.

The study measured the accuracy of the Italian version of the Mood Disorder Questionnaire (MDQ) as a screening instrument for bipolar disorders in a psychiatric setting. 154 consecutive subjects attending the Division of Psychiatry of the University of Cagliari (Italy), were screened for bipolar disorders using the Italian translation of the MDQ, and diagnostically interviewed with the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID) by physicians. On the basis of the SCID: 51 (33.1%) received a diagnosis of bipolar or schizoaffective bipolar type disorders, 63 (40.9%) were diagnosed as having at least one psychiatric disorder in Axis I (other than bipolar or schizoaffective bipolar type disorders), whilst 40 (25.9%) were unaffected by any type of psychiatric disorder. MDQ showed a good accuracy for bipolar or schizoaffective bipolar type disorders: the cut-off 4 had sensitivity 0.90 and specificity 0.58; the cut-off 5 had sensitivity 0.84 and specificity 0.70; and t...

Changes in biological rhythm are among the various characteristics of bipolar disorder, and have long been associated with the functional impairment of the disease. There are only a few viable options of psychosocial interventions that deal with this specific topic; one of them is psychoeducation, a model that, although it has been used by practitioners for some time, only recently have studies shown its efficacy in clinical practice. Aim: To assess if patients undergoing psychosocial intervention in addition to a pharmacological treatment have better regulation of their biological rhythm than those only using medication. Method: This study is a randomized clinical trial that compares a standard medication intervention to an intervention combined with drugs and psychoeducation. The evaluation of the biological rhythm was made using the Biological Rhythm Interview of Assessment in Neuropsychiatry, an 18-item scale divided in four areas (sleep, activity, social rhythm, and eating pattern). The combined intervention consisted of medication and a short-term psychoeducation model summarized in a protocol of six individual sessions of 1 hour each. Results: The sample consisted of 61 patients with bipolar II disorder, but during the study, there were 14 losses to follow-up. Therefore, the final sample consisted of 45 individuals (26 for standard intervention and 19 for combined). The results showed that, in this sample and time period evaluated, the combined treatment of medication and psychoeducation had no statistically significant impact on the regulation of biological rhythm when compared to standard pharmacological treatment. Conclusion: Although the changes in biological rhythm were not statistically significant during the time period evaluated in this study, it is noteworthy that the trajectory of the score showed a trend towards improvement, which may indicate a positive impact on treatment, though it may take a longer time than expected.
Development and use of a biological rhythm interview
Journal of Affective Disorders, 2009
Introduction: As several lines of evidence point to irregular biological rhythms in bipolar disorder, and its disruption may lead to new illness episodes, having an instrument that measures biological rhythms is critical. This report describes the validation of a new instrument, the Biological Rhythms Interview of Assessment in Neuropsychiatry (BRIAN), designed to assess biological rhythms in the clinical setting.
