Smoking Addiction in Patients with Schizophrenia Spectrum Disorders and Its Perception and Intervention in Healthcare Personnel Assigned to Psycho-Rehabilitation Programs: A Qualitative Research

Patients with schizophrenia spectrum disorders have a higher prevalence and frequency of smoking rates when compared to the rest of the population; to this, it must be added that they develop a greater dependence and have some worse health consequences than the general population. This is qualitative research on the perception of smoking in healthcare professionals assigned to psycho-rehabilitation programs for patients with schizophrenia spectrum disorders. The point of view of health personnel (Psychologists, Psychiatrists, Pedagogists, and Nurses) about cigarette smoking in these patients was analyzed, focusing on their implications in disturbance and comparing them with e-cigarettes too. The methodology used to collect the data was a semi-structured interview with five questions. The research path was carried out in two assisted therapeutic communities that are clinics for the rehabilitation of serious mental illness in the period between November and July 2022. The results showed that the opinion of health professionals on smoking is very negative. Research has also shown that nearly all patients are smokers; however, their high grade of addiction is caused by periods of high stress due to various factors that lead patients to consume a greater number of cigarettes. Almost all respondents have a positive opinion of the e-cigarette, which was defined as an excellent substitute for traditional cigarettes.

Structural validity of the Eating Disorder Examination-Questionnaire: A systematic review

OBJECTIVE

The main aim was to perform a systematic literature review of studies investigating the factor structure of the Eating Disorder Examination-Questionnaire (EDE-Q), a widely used measure of eating pathology. Secondary aims were to summarize the quality of reporting of latent variable (factor) analyses in these studies and review support for different factor solutions.

METHOD

Literature was identified through Scopus, Medline, PsycInfo, and ProQuest databases published up to February 23, 2022 and outreach via an international listserv. All studies published in English reporting factor analysis of the EDE-Q were included with few restrictions. Sixty studies including 63,389 participants met inclusion criteria.

RESULTS

The originally proposed four-factor solution received little empirical support, although few alternative models have been robustly evaluated. Items assessing shape and weight concerns frequently coalesce in factor solutions, suggesting that these constructs are closely related. Investigations of brief versions of the EDE-Q have produced more consistent findings, suggesting that these measures, particularly a seven-item version, might be useful alternatives to the full version. Quality of studies was reasonable, with important methodological elements of factor analysis often reported.

DISCUSSION

The findings are of relevance to practitioners and researchers, suggesting that the "original" factor structure of the EDE-Q should be reconsidered and that use of a seven-item version is to be encouraged.

PUBLIC SIGNIFICANCE

Self-report questionnaires are widely used in the assessment of disordered eating. The current study found that there is little consensus about the structure of a common measure of eating psychopathology. There is more consistent support for a brief, seven-item, version assessing dietary restraint, body dissatisfaction, and overvaluation of weight and shape.

Factor Structure of the Repeatable Battery for the Assessment of Neuropsychological Status in Huntington's Disease

OBJECTIVE

The Repeatable Battery for the Assessment of Neuropsychological Status is a commonly used neuropsychological screening tool that is useful in a Huntington's disease (HD) population given its relatively brief administration time and assessment of multiple cognitive domains. Although 5 index scores are calculated, this structure has not been universally supported in clinical samples, which have often found a two- and three-factor structure to be better fitting. This study explored the Repeatable Battery for the Assessment of Neuropsychological Status factor structure in a large HD sample, which has not been done to date.

METHOD

In total, 147 individuals with HD completed the Repeatable Battery for the Assessment of Neuropsychological Status. An exploratory factor analysis was conducted to explore the Repeatable Battery for the Assessment of Neuropsychological Status factor structure.

RESULTS

Consistent with the findings from a majority of other clinical samples investigated, our results revealed a better fitting two-factor structure (verbal and visual).

CONCLUSION

The traditional Repeatable Battery for the Assessment of Neuropsychological Status index structure may not be valid in HD, which yields important clinical and research implications.

Posttraumatic Stress Disorder-Associated Cognitive Deficits on the Repeatable Battery for the Assessment of Neuropsychological Status in a Veteran Population

Background

Posttraumatic stress disorder (PTSD) is a frequent problem of veterans receiving care and is often associated with cognitive deficits. The Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) is a well-validated cognitive screening measure often used in the US Department of Veterans Affairs (VA), particularly in neurorehabilitation settings. However, the influence of PTSD on RBANS performance is unclear, particularly within a heterogeneous VA outpatient population in which PTSD and traumatic brain injury (TBI) may not be the primary focus of care.

Methods

Participants included 153 veterans with complex deployment-related health problems, including a diagnosis of PTSD (n = 98) and a history of TBI (n = 92). All veterans completed a targeted cognitive battery that included the Wechsler Test of Adult Reading, the Wechsler Adults Intelligence Scale, measure assessing processing speed, attention, and cognitive flexibility, and RBANS.

Results

A diagnosis of PTSD was associated with worse performance on the Story Recall subtest of the RBANS, but not on any other cognitive measures. A diagnosis of mild TBI, or co-occurring PTSD and TBI did not predict cognitive performance on any measures.

Conclusions

The RBANS best captured cognitive deficits associated with PTSD compared with a history of mild TBI or co-occurring mild TBI and PTSD. These findings may provide insight into the interpretation and attribution of cognitive deficits in the veteran population.

Reconsidering the RBANS Factor Structure: a Systematic Literature Review and Meta-Analytic Factor Analysis

The primary aim was to perform a systematic literature review and extract data necessary for a meta-analytic factor analysis of the RBANS. Secondary aims were to examine the potential validity and utility of the resulting factor structure. Literature was identified through a review of PsycINFO, PubMed, MEDLINE, Academic Search Complete, Psychology & Behavioral Sciences Collection, CINAHL Complete, Health Source: Nursing/Academic Edition, and SocINDEX. A two-stage meta-analytic structural equation modeling method was implemented to pool correlation matrices from primary studies and perform confirmatory factor analyses. Following model selection, factor scores were computed for two datasets and subjected to correlation and diagnostic accuracy analyses. A pooled correlation matrix was computed from 24 sample correlation matrices (N = 5299). Confirmatory factor analysis revealed that the theoretical five-factor model produced the best fit but only when error terms between Story Memory and Story Recall as well as between Figure Copy and Figure Recall were included. Regression-based factor scores showed mixed relationships with the manual-defined indices, and the overall diagnostic accuracy of the factor scores was adequate in both samples examined (AUC = 0.71 and 0.87). The five-factor model was an unexpected result given the failure of multiple previous studies to find support for that model. The five-factor model demonstrates several areas of potential improvement, including better representation of the factors by the indicators. The factor scores implied by this model also require further validation.

Education Differentially Buffers Cognitive Performance in Black and White Older Adults

OBJECTIVES

Given that black American older adults are more likely to have lower educational attainment and perform worse on cognitive tests than white Americans, we examined whether increased education would confer greater cognitive advantage to black Americans on measures of global and specific domains of cognitive function.

METHODS

The sample included 522 community-dwelling older adults from a larger study. An analysis of covariance was conducted with race and education as between-participant factors and global cognition as the dependent variable. A multivariate analysis of covariance was conducted with five cognitive domains (immediate memory, visuospatial/constructional ability, language, attention, and delayed memory) as the dependent variables.

RESULTS

Significant main effects indicated that black Americans, F(1,516) = 29.18, p < .001, and individuals with less education, F(1,516) = 44.93, p < .001, evidenced lower cognitive functioning, controlling for age and overall health status, and the interaction term reached statistical significance, F(1,516) = 7.95, p = .005. The impact of education on global cognitive function for black participants was more than twice as large (Cohen's d = 1.30) than for white participants (Cohen's d = .52). There was a significant race × education interaction for the cognitive domain of attention (p < .001) and a composite measure of non-memory domains (i.e., language, visuospatial/constructional, and attention; p < .001).

DISCUSSION

Our findings suggest that educational attainment is particularly important for black Americans with respect to global cognitive function, attention, and non-memory domains.

Five-factor structure of the RBANS is supported in an Alzheimer's disease sample: Implications for validation of neuropsychological assessment instruments

Development of the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) was theoretically driven, with the goal of providing an assessment of abilities across five cognitive domains. Since its development, numerous factor analytic studies have failed to provide empirical support for the proposed five-factor structure and, furthermore, have lacked consensus on the internal structure of this instrument. A key limitation of these prior studies is the use of normal or mixed clinical samples, a practice that can obscure distinctions that may be evident in specific homogeneous clinical samples. The current study examined the factor structure of the RBANS in a sample of 107 male Veterans diagnosed with probable Alzheimer's disease (AD). Confirmatory factor analysis of a model reflecting the five Index Scores (Immediate Memory, Visuospatial/Constructional, Language, Attention, and Delayed Memory) found that the proposed five-factor structure fit the data well. These findings suggest that the RBANS does measure five distinct constructs and use of Index Scores is appropriate. Furthermore, the current findings highlight the importance of testing construct validity of neuropsychological assessment instruments in specific homogeneous samples.

Rescuing Suboptimal Patient-Reported Outcome Instrument Data in Clinical Trials: A New Strategy

Background: Psychometric instruments such as the Repeated Battery for the Assessment of Neuropsychological Status (RBANS) are commonly used under conditions for which they were not developed or validated. They may then generate troublesome data that could conceal potential findings. Methods: Based on a previously published refinement of the RBANS, we reanalyzed the data on 303 patients from two National Institutes of Health (NIH) trails in Parkinson’s disease and contrasted the results using the original versus refined scores. Results: Findings from the original RBANS scores were inconsistent; however, use of the refined scores produced potential findings that were in agreement with independent reports. Conclusion: This study demonstrates that, for negative trials using instrument scores as primary outcomes, it is possible to rescue potential findings. The key to this new strategy is to validate and refine the instrument for the specific disease and conditions under study and then to reanalyze the data. This study offers a demonstration of this new strategy for general approaches.
