The Brief Symptom Inventory (BSI) as a screening tool for psychological disorders in patients with epilepsy and mild intellectual disabilities in residential care

Process-oriented and personalized psychotherapeutic care for epilepsy: Interim results of a feasibility study

BACKGROUND

There is great scientific and clinical interest in the effective integration of psychological treatments into comprehensive epilepsy care to optimize treatment outcomes and psychosocial functioning in people with epilepsy. Stepped care is a promising approach to accommodate personalized psychotherapeutic care in academic and regular outpatient settings. It aims at providing patients with the most adequate treatment duration, number of sessions, and treatment method while systematically monitoring their treatment processes.

METHODS

This is an uncontrolled feasibility study of process-oriented and personalized psychotherapeutic care for epilepsy in a naturalistic setting. The objective of this study was to evaluate individual changes of health-related quality of life (QOLIE-31) and psychiatric comorbidity (BDI-II, BSI) in participants by applying the concept of the reliable change index (RCI) to outcomes that were obtained at baseline and six months after the beginning of the intervention. Additionally, we assessed the relationship between outcome scores, the number of attended sessions, and history of childhood trauma by linear regression models.

RESULTS

Twenty patients [15 women/5 men, median age 48 years (range: 23-73 years)] were recruited. The median number of scheduled sessions was 11 (range: 6-22); there were no drop-outs. After psychotherapy quality of life (QOLIE-31), global distress (BSI) and depression (BDI-II) scores improved significantly (p-values: QOLIE-31: 0.03; BSI: 0.01; BDI-II: 0.01). The largest improvements were achieved for the emotional well-being subscale of the QOLIE-31 (47%, p-value: 0.02), the global severity index of the BSI (83%), and depression severity (BDI-II) (60%). Linear regression models did not reveal any significant association between interim changes, number of attended treatment sessions, and history of childhood trauma.

CONCLUSION

The results suggest that process-oriented and personalized psychotherapeutic has low attrition and results in improved quality of life and reduced psychiatric symptoms in people with epilepsy. Our findings indicate that responsiveness to psychotherapy is not dependent on the number of attended treatment sessions. Participants with childhood trauma did not need more treatment sessions to achieve an improvement. More research is needed to understand and address mechanisms and precursors of responsiveness to psychotherapy.

Abbreviated assessment of psychopathology in patients with suspected seizure disorders

PURPOSE

Psychopathology is common in patients undergoing investigation for seizure-related disorders. Psychometric examination using self-report instruments, such as the Symptom Checklist 90 - Revised (SCL-90-R), can assist diagnosis. The SCL-90-R, however, is a lengthy instrument and might not be tolerated by all patients. We assessed several abbreviated forms of the SCL-90-R in patients undergoing video encephalographic monitoring (VEM).

METHOD

Six hundred eighty-seven patients completed the SCL-90-R, and scores were computed for the full SCL-90-R and five abbreviated forms. Correlations and mean differences were computed between different forms. Classification accuracy was assessed via receiver operating characteristic (ROC) curves, and measurements models were examined using confirmatory factor analysis (CFA).

RESULTS

All abbreviated forms were strongly correlated with the SCL-90-R for general psychopathology (r = 0.93-0.99), depression (r = 0.89-0.95), anxiety (r = 0.97-0.98), psychosis (r = 0.95-0.99), and obsessive-compulsive symptoms (r = 0.97). Classification performance was similar across forms for depression and anxiety, with high negative predictive values (0.90-0.94) and lower positive predictive values (0.34-0.38). Classification performance for psychotic and obsessive-compulsive disorders was poor. Differences were observed between the full SCL-90-R and its abbreviated forms across most domains (d = 0.00-0.65). The published measurement model was most strongly validated for the SCL-27, SCL-14, and the SCL-K-9.

CONCLUSIONS

These five SCL-90-R abbreviated forms show high convergent validity with the full version. In patients undergoing investigation for seizure-related disorders, the Brief Symptom Inventory full form (BSI) or short form (BSI-18) is most appropriate where screening for both depression and anxiety is required. The SCL-K-9 is appropriate when only a single measure of global psychological distress is required. None of the instruments were able to detect psychotic or obsessive-compulsive symptoms with great accuracy. Caution should be exercised when making direct comparisons across the different forms.

Psychometric properties of the Brief Symptom Inventory in nomophobic subjects: insights from preliminary confirmatory factor, exploratory factor, and clustering analyses in a sample of healthy Italian volunteers

Background

The Brief Symptom Inventory (BSI), developed by Derogatis in 1975, represents an important standardized screening instrument that enables one to quantitatively assess psychological distress and psychiatric disorders. The BSI is a 53-item self-report scale, measuring nine dimensions that can be summed up to reflect three global indices, including the General Severity Index (GSI). In the era of new information and communication technologies, nomophobia (“no mobile phobia”) is an emerging disorder, characterized by the fear of being out of mobile phone contact. Nothing is known, however, about the factor structure and reliability of the BSI in a population of nomophobic subjects. This study aimed at addressing this gap in knowledge.

Methods

A sample of 403 subjects aged 27.91±8.63 years (160 males, 39.7% of the entire sample, and 243 females, 60.3%), recruited via snowball sampling, volunteered to take part in the study. The Italian versions of the Nomophobia questionnaire and the BSI were administered. Exploratory factor analyses, confirmatory factor analyses, and clustering analysis were carried out together with correlation analysis, analysis of variance, and multivariate regression analysis.

Results

For each BSI subscale, scores were significantly higher than the norms. The nine subscales exhibited acceptable-to-good Cronbach’s alpha coefficients, varying from 0.733 for psychoticism to 0.875 for depression. Overall, the reliability of the entire instrument proved to be excellent (alpha coefficient=0.972). Furthermore, all BSI subscales as well as BSI synthetic indexes correlated with nomophobia in a significant way. Stratifying the population according to the severity of nomophobia (mild, 206 individuals, 51.1% of the sample; moderate, 167 subjects, 41.4%; and severe, 30 individuals, 7.4%), the GSI score could distinguish (P<0.001) between mild and moderate (0.99±0.71 vs 1.32±0.81) and between mild and severe (0.99±0.71 vs 1.54±0.79) nomophobia, although not between moderate and severe nomophobia (P>0.05). Similar patterns could be found for the other subscales of the BSI. Finally, looking at the fit indexes, the second-order 9-factor model best fit the data compared with the Derogatis 1-factor model.

Conclusion

The findings of our study show that the BSI is a reliable and valid instrument with acceptable psychometric properties, and can be administered to populations of nomophobic subjects.

Willingness to Seek Treatment Among Black Students With Anxiety or Depression: The Synergistic Effect of Sociocultural Factors With Symptom Severity and Intolerance of Uncertainty

Anxiety and depressive disorders are among the most commonly diagnosed psychiatric disorders, yet they remain largely undertreated in the U.S. and Black adults are especially unlikely to seek or receive mental health services. Symptom severity has been found to impact treatment-seeking behaviors as have sociocultural factors. Yet no known research has tested whether these factors work synergistically to effect willingness to seek treatment. Further, emerging data point to the importance of transdiagnostic risk factors such as intolerance of uncertainty (IU). IU may be negatively related to seeking treatment given that Black adults may be uncertain whether treatment might benefit them. Thus, the current study examined the relations between symptom severity/IU and willingness to seek treatment for anxiety/depression problems and the impact of key sociocultural variables (i.e., cultural mistrust-interpersonal relations [CMI-IR], perceived discrimination [PED]) on these relations among 161 (85% female) Black undergraduates. Consistent with prediction, symptom severity was positively related to willingness, but unexpectedly, IU was positively related. There was a significant Symptom Severity × CMI-IR interaction such that severity was positively related to willingness among students with lower cultural mistrust, but not higher mistrust. There were also significant IU × PED interaction such that IU was positively related to willingness among students with lower PED, but not higher PED. Results highlight the importance of considering the interplay between symptom severity, transdiagnostic vulnerability factors, and sociocultural variables when striving to identify factors related to treatment seeking behaviors among anxious and/or depressed Black students.

A cross-sectional study of family caregiver burden and psychological distress linked to frailty and functional dependency of a relative with advanced dementia

Psychological health of caregivers of people with dementia is a major public concern. This study sought to determine the relationship between caregiver burden, psychological distress, frailty and functional dependency of a relative with advanced dementia. Persons with dementia and their caregivers (102 dyads) participated in this Portuguese community based cross-sectional study. Data were collected using the Clinical Dementia Rating Scale, a sociodemographic questionnaire, the Zarit Burden Interview, the Brief Symptoms Inventory and the Edmonton Frail Scale. Alzheimer's disease was the most common type of dementia among the recipients of care, who showed moderate (42.2%) to severe (52.9%) dementia. Among them 35.3% exhibited moderate and 45.1% severe frailty. Family caregivers reported moderate (76.5%) to severe burden (18.6%). Psychological distress was very high among family caregivers. Results show that people with dementia exhibited moderate (35.3%) or severe frailty (45.1%) and that a severe frailty was found in people with moderate dementia. A one-way ANOVA was conducted between the Global Severity Index and some sociodemographic variables. ANOVA reached p < .01 for employment status of the caregiver, assistance and professional support, and psychiatric history; and p = 0.01 for caregiver age and years of caregiving. Although caregivers reported benefit from the supportive approach offered by the multidisciplinary home care team, high levels of distress and associated burden were found, which might decrease their capacity to care for the person with dementia and their own health and well-being.

The experience of psychological distress in family caregivers of people with dementia: A cross-sectional study

PURPOSE

To evaluate the degree of psychological distress in family caregivers of people with dementia.

DESIGN AND METHODS

A nonprobabilistic sample of 54 dyads (people with dementia and family caregivers) was recruited. A sociodemographic questionnaire, the Brief Symptom Inventory (BSI), and the Barthel Index were used for data collection.

FINDINGS

About half of the caregivers had significant levels of psychological distress. Caregivers showed high scores in some BSI dimensions: somatization, obsessive-compulsion, interpersonal sensitivity, anxiety, and paranoid ideation.

PRACTICE IMPLICATIONS

Alleviating the caregivers' distress is likely to have positive effects on the overall health and capacity to care. Frameworks for providing palliative care to people with advanced dementia and support the caregivers would enhance the quality of care provided and may reduce the distress on the caregiver.

The physical postures of yoga practices may protect against depressive symptoms, even as life stressors increase: a moderation analysis

Yoga contains sub-components related to its physical postures (asana), breathing methods (pranayama), and meditation (dhyana). To test the hypothesis that specific yoga practices are associated with reduced psychological distress, 186 adults completed questionnaires assessing life stressors, symptom severity, and experience with each of these aspects of yoga. Each yoga sub-component was found to be negatively correlated with psychological distress indices. However, differing patterns of relationship to psychological distress symptoms were found for each yoga sub-component. Experience with asana was negatively correlated with global psychological distress (r = -.21, p < .01), and symptoms of anxiety (r = -.18, p = .01) and depression (r = -.17, p = .02). These relationships remained statistically significant after accounting for variance attributable to Social Readjustment Rating Scale scores (GSI: r = -.19, p = .01; BSI Anxiety: r = -.16, p = .04; BSI Depression: r = -.14, p = .05). By contrast, the correlations between other yoga sub-components and symptom subscales became non-significant after accounting for exposure to life stressors. Moreover, stressful life events moderated the predictive relationship between amount of asana experience and depressive symptoms. Asana was not related to depressive symptoms at low levels of life stressors, but became associated at mean (t[182] = -2.73, p < .01) and high levels (t[182] = -3.56, p < .001). Findings suggest asana may possess depressive symptom reduction benefits, particularly as life stressors increase. Additional research is needed to differentiate whether asana has an effect on psychological distress, and to better understand potential psychophysiological mechanisms of action.

Psychopathological Dimensions in Portuguese Subjects with Transthyretin Familial Amyloid Polyneuropathy

Background

Transthyretin familial amyloid polyneuropathy (TTR-FAP) is a fatal, chronic, progressive disease. It is a rare hereditary amyloidosis, which manifests as a sensorimotor neuropathy and autonomic dysfunction. It begins during adulthood.

Aims and Methods

Our aim is to evaluate psychopathological dimensions in a population attending a consultation center for TTR-FAP. Two hundred and nine subjects (symptomatic and asymptomatic carriers), 84 men and 127, women participated in the study. Most subjects were married (67.1%) and most of them were still working; 33% were retired from work or on a sick leave. A sociodemographic questionnaire and The Brief Symptom Inventory (BSI) were applied. Statistical analysis was performed (descriptive analysis, Mann-Whitney, Wilcoxon, and Spearman tests).

Results

The Global Symptom Index (GSI) was significantly higher in patients (p = 0.001). Considering GSI, 32.7% of total subjects were above the median for general population. When subgroups were evaluated, 25.6% of symptomatic carriers, 26.3% of subjects without established diagnosis, and 39.1% of patients were above median. GSI was significantly higher in patients (p = 0.001). Some BSI dimensions were also significantly higher in the patient group (somatization, depression, anxiety, and psychoticism) when compared with carriers. Women scored higher than men. Sick women scored higher for all dimensions except somatization. Asymptomatic carriers scored statistically higher for phobic anxiety (p = 0.01), interpersonal sensitivity, anxiety, and depression. In patients, most dimensions and GSI (rho = 0.33, p = 0.002) had positive correlations with years of disease.

Conclusions

TTR-FAP patients and carriers are a very vulnerable group for psychological distress and psychopathological problems. Women and patients are at higher risk.

Validity of the Brief Symptom Inventory-18 (BSI-18) for identifying depression and anxiety in young adult cancer survivors: Comparison with a Structured Clinical Diagnostic Interview

The Brief Symptom Inventory-18 (BSI-18) is widely used to assess psychological symptoms in cancer survivors, but the validity of conventional BSI-18 cut-off scores in this population has been questioned. This study assessed the accuracy of the BSI-18 for identifying significant anxiety and depression in young adult cancer survivors (YACS), by comparing it with a "gold standard" diagnostic interview measure. Two hundred fifty YACS, age 18-40 completed the BSI-18 and the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders (DSM-IV; SCID) interview assessing anxiety and depressive disorders. BSI-18 results were compared with SCID criteria using receiver operating characteristics (ROC) analyses. Forty four participants (17.7%) met criteria for ≥1 SCID diagnoses, and an additional 20 (8.0%) met criteria for clinically significant SCID symptoms without a diagnosis. General concordance between the BSI-18 GSI scale and SCID diagnosis was good (AUC = 0.848), but the 2 most widely used BSI-18 case rules failed to identify a majority of survivors with SCID diagnoses, and no alternative BSI-18 cut-off scores met study criteria for clinical screening. Analyses aimed at identifying survivors with significant SCID symptoms or a SCID diagnosis had similar results, as did analyses examining depression and anxiety separately. The BSI-18 shows good overall concordance with a psychiatric interview, but recommended cut-off scores fail to identify a majority of YACS with psychiatric diagnosis. Clinicians should not rely on the BSI-18 alone as a screening measure for YACS. Alternative BSI-18 scoring algorithms optimized for detecting psychiatric symptoms in YACS may be an important step to address this limitation. (PsycINFO Database Record

Gender differences in outpatients with anxiety disorders: the Leiden Routine Outcome Monitoring Study

BACKGROUND

Data from the general population show higher prevalence of different anxiety disorders in women as compared with men. We analysed gender differences in a naturalistic sample of outpatients with anxiety disorders in a mental healthcare setting.

METHOD

Routine outcome monitoring data were collected from 1333 patients (age: 18-65; 63.3% women) fulfilling Diagnostic and Statistical Manual of Mental Disorders IV criteria of current anxiety disorder according to the Mini-International Neuropsychiatric Interview between 2004 through 2006. Data included Comprehensive Psychopathological Rating Scale, Brief Symptom Inventory (BSI), Short Form Health Survey (SF-36), Mood and Anxiety Symptom Questionnaire (MASQ). Chi-squared test and t-test were used to compare women with men for variables with parametric distributions, and Mann-Whitney test for non-parametric distribution. Adjustments for potential confounders (age, level of education, ethnicity and comorbidites) were made by logistic regression models (for discrete variables) or analysis of covariance.

RESULTS

The female-to-male ratio (i.e., 844 women, 489 men) for any anxiety disorder was 1.73 : 1 (95% confidence interval [CI]: 1.63-1.83), with the strongest skewness for post-traumatic stress disorder (2.80 : 1) and the smallest one for social phobia (1.18 : 1). Compared with men, women reported more severe self-rating scores on the BSI (on average, the scores were 12.3% higher on 3 of 9 subscales: somatisation, interpersonal sensitivity and anxiety), SF-36 (self-reported generic health status was lower on 5 of 8 subscales: physical functioning, social functioning, physical problems, vitality and bodily pain) and MASQ (on average, the scores were 6.6% higher on 4 of 5 subscales: anxious arousal, general distress, general distress depression, general distress anxiety). On the contrary, no gender difference was found in the severity of anxiety symptoms measured by the Brief Anxiety Scale. Women were more likely to suffer from comorbid depression and bulimia nervosa, and less likely from substance abuse.

CONCLUSIONS

In a treatment-seeking population the prevalence rate of anxiety disorders was 1.7 times higher in female compared with men. Female outpatients were more severely affected on self-rated but not on observer-rated scales.

The Psychometric Properties of the Brief Symptom Inventory in Men under Criminal Justice Involvement: Implications for Forensic Social Workers in Practice Settings

The purpose of this study was to assess the factor structure and psychometric properties of the original and a revised modification of the Brief Symptom Inventory (BSI) in 259 black and Latino males, aged thirty-five to sixty-seven, who had been released from a New York state prison or a New York City jail. The data were analysed using exploratory factor analysis, principal axis factoring and confirmatory factor analysis. Standardised factor loadings were evaluated at 0.05, model fit was evaluated using the chi-square statistic, and fit indices were examined. Items whose communalities fell below 0.30 were eliminated from the procedure. The findings did not yield the same number of factors as the original BSI, but the revised BSI model fitted the current data better. This modified factor structure reduced the BSI to the nineteen most appropriate items to assess five key common psychiatric symptoms affecting men under community supervision. The results of the current factor structure suggest that the psychiatric disorders experienced by men under community supervision may differ from the populations studied by the original BSI factor structure. Forensic social work ought to examine the psychometric properties of standardised measures for different populations such that appropriate instruments may be specifically targeted and maximised.

The autobiography of addiction: autobiographical reasoning and psychological adjustment in abstinent alcoholics

The narration of drinking experiences plays a central role in many alcohol rehabilitation programmes, yet few researchers have considered whether alcoholics' stories about such experiences relate to their psychological adjustment. Here we examine the extent to which drinking stories of abstinent alcoholics reflect autobiographical reasoning processes denoting self-change and self-stability, and whether these processes are associated with adjustment. Participants who revealed a positive self-change in their narratives about drinking demonstrated higher levels of self-esteem, authentic pride, and mental health compared to those who did not. In contrast, those who implied a sense of self-stability in their narratives demonstrated higher levels of hubristic pride and aggression, and poorer mental health. These results suggest that narrating positive self-change in the wake of substance abuse may underlie psychological adjustment, whereas establishing self-stability in these experiences may impede adjustment. More broadly, these findings underscore the importance of recognising the multi-dimensional nature of autobiographical reasoning.

Utility of the Brief Symptom Inventory (BSI) in psychiatric outpatients with intellectual disabilities

BACKGROUND

Diagnostics and care for people with intellectual disabilities (ID) and psychiatric disorders need to be improved. This can be done by using assessment instruments to routinely measure the nature and severity of psychiatric symptoms. Up until now, in the Netherlands, assessment measures are seldom used in the psychiatric care for this population. The objective of the present paper is to evaluate the use of the Brief Symptom Inventory (BSI), a widely used standardised questionnaire in general psychiatry, in a well-defined sample of people with borderline intellectual functioning or mild ID diagnosed with one or more psychiatric disorders.

METHODS

A total of 224 psychiatric outpatients with either borderline intellectual functioning or mild ID participated in this study. All participants were new patients of Kristal, Centre for Psychiatry and Intellectual Disability in the Netherlands, in the period between 1 April 2008 and 1 October 2009. All participants were assessed by a multidisciplinary team, including a certified psychiatrist. Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR) criteria were applied. The mean total intelligence quotient was measured with the Wechsler Adult Intelligence Scale (WAIS-III). The BSI was administered in an assisted fashion. Utility and psychometric properties of the BSI were investigated. Internal consistency coefficients (Cronbach's alphas) were computed. Bivariate correlations between the sub-scales were computed to assess differentiation between the scales. Mean sub-scale scores were compared between different DSM-IV-TR subgroups to investigate the discriminant abilities of the scales. A confirmatory factor analysis was conducted.

RESULTS

The results suggest that the BSI is practically useful. Internal consistencies ranged from 0.70 to 0.96 and thus are considered good to adequate. Sub-scale inter-correlations showed there is a degree of differentiation between the sub-scales. Discriminant validity was shown for the sub-scales depression, anxiety and phobic anxiety. Confirmatory factor analysis showed that the underlying structure of the BSI could be described by the same nine-factor model as reported in previous studies.

CONCLUSIONS

As a result of the psychometric properties illustrated, this study supports the use of the BSI as a screener for psychopathology and a general outcome measure in people with ID.

The psychometric properties of the Brief Symptom Inventory depression and anxiety subscales in patients with heart failure and with or without renal dysfunction

More than 5 million Americans have heart failure (HF); approximately one third have concomitant renal dysfunction. Anxiety and depressive symptoms are the most common psychological responses of these individuals and may influences outcomes; thus a reliable valid instrument to measure these is needed. This article reports a psychometric evaluation of the Brief Symptom Inventory (BSI) depression and anxiety subscales in patients with HF and with or without renal dysfunction, as these scales are commonly used in this population for research studies. This rigorous psychometric analysis used existing data from 590 patients with HF with an average ejection fraction of 35% ± 15% and average age of 63 ± 13 years. Patients were categorized as normal renal function (n = 495) or renal dysfunction (n = 95), and groups were compared and analyzed separately. Cronbach's alpha for the BSI subscales was .82 for those with normal renal function and .88 for those with renal dysfunction. Factor analysis determined that the subscales evaluated one dimension, psychological distress, in both groups. Construct validity was examined using hypothesis testing, and construct validity was supported in patients with HF and with normal renal function by significant associations of the BSI subscales with another measure of depression and a measure of perceived control. Construct validity in patients with HF and renal dysfunction was not strongly supported. Only the BSI depression subscale predicted poorer outcomes in patients with HF and with normal renal function; neither subscale was associated with event-free survival at 12 months in those with renal dysfunction. The BSI anxiety and depression subscales provide reliable and valid data in patients HF and normal renal function. Although reliability is excellent, construct validity was weak in those patients with HF and with concomitant renal dysfunction, which may reduce the validity of those data.

Quality of life among people with epilepsy and mild intellectual disabilities in residential care

This study examined quality-of-life (QOL) evaluations among people with epilepsy and mild intellectual disabilities in residential care to determine their covariation and potential determinants. Participants were 111 clients of the Bethel Institute, Bielefeld, Germany. They completed questionnaires on their overall QOL and life satisfaction, the PESOS scales on epilepsy-related QOL, the Brief Symptom Inventory (BSI), and scales on activities of daily life and work-related problems in face-to-face-interviews. QOL evaluations differed in the various domains and tended to be better on more concrete items. Correlations of generic QOL parameters with scales on epilepsy-related QOL were only weak. BSI scores reflecting the current emotional state were identified as the most influential predictors of all QOL measures. The weak relationship between non-health-related parameters of subjective QOL and epilepsy-related QOL requires further investigation and theoretical explanation, whereas the influence of negative affect on different QOL dimensions is in line with previous QOL findings.

Eye movement desensitization and reprocessing in the treatment of posttraumatic stress disorder in a patient with comorbid epilepsy

Whether eye movement desensitization and reprocessing (EMDR) treatment of posttraumatic stress disorder (PTSD) causes reactivation of epilepsy is as yet unclear. A 34-year-old woman was treated in an inpatient multimodal psychotherapeutic setting with EMDR for PTSD resulting from sexual harassment and for a moderate depressive episode. She had been diagnosed with idiopathic generalized absence epilepsy in childhood, but had experienced no seizures under lamotrigine medication since 1999. After the second EMDR session, clinical seizures in the form of absences occurred, and were validated by electroencephalography. The seizures ceased after medication with benzodiazepines and an increase in the lamotrigine level. She underwent four more sessions of EMDR treatment successfully without further seizures. Possible triggers are discussed, especially as to whether EMDR treatment played a role in reactivating epilepsy. Further research and publications on the application of EMDR in epilepsy patients are needed.
