What Information Do Neuropsychologists Use to Guide their Clinical Decisions? A Survey on Knowledge and Application of Evidence-Based Practice in a French-Speaking Population.

OBJECTIVE: Evidence-based practice (EBP) is an approach that encourages clinicians to base their practice on evidence to improve the quality of patient care and reduce uncertainty in their clinical decisions. However, the state of knowledge and practice of neuropsychologists in French-speaking countries is still unknown. This study aimed to find out what these neuropsychologists know about EBP and whether they use it. METHOD: A questionnaire with 39 questions for French-speaking neuropsychologists was distributed. The questions focused on neuropsychologists' knowledge and use of EBP and information that guide their clinical decisions. RESULTS: A total of 392 respondents started the survey. The data show that only 35% correctly defined EBP and there was confusion between this practice and the strict use of research data. In practice, their decisions are influenced by multiple factors, including the patient's difficulties and advice from peers. Regarding the research, a significant proportion of the sample stated that they did not search the scientific literature frequently. Barriers to accessing scientific information and ineffective article-reading behavior were highlighted. CONCLUSION: A lack of knowledge of EBP among French-speaking neuropsychologists was observed. Furthermore, the factors influencing their decision-making do not clearly fit the definitions of EBP. Information-seeking behaviors show several weaknesses and barriers to the integration of scientific evidence into practice. These results are like those of other studies conducted among psychologists or in other health professions. We will discuss possible courses of action that could be implemented to improve the knowledge and use of EBP.

Social cognition in neuropsychology: A nationwide survey revealing current representations and practices.

As a key domain of cognition, social cognition abilities are altered in a wide range of clinical groups. Accordingly, many clinical tests and theories of social cognition have been developed these last decades. Contrasting this abundant development from a research perspective, recent evidence suggests that social cognition remains rarely addressed from a clinial perspective. The aim of the present research was to characterize the current practices, representations, and needs linked to social cognition from the perspective of professional neuropsychologists and graduate students. A nationwide survey allowed us to determine the classical field conception of social cognition and its associated symptoms or notions. It also allowed us to quantify practice activities and the use of the different clinical tools available. This study revealed that neuropsychologists lack confidence regarding social cognition assessment and its rehabilitation, and that students are in demand for more knowledge and training. Suggestions of change in practices and dissemination of knowledge are discussed. Considering the importance of social cognition, an extension of initial and continuous training alongside an enrichment of interactions between researchers and clinicians were key recommendations to formulate, as well as the need for a consensual lexicon of current concepts.

Cognitive assessment scale for stroke patients (CASP): A multicentric validation study.

BACKGROUND: The Mini Mental State Examination and Montreal Cognitive Assessment are commonly used as short screening batteries for assessing cognitive impairment after stroke. However, aphasia or hemispatial neglect may interfere with the results. For this reason, we developed the Cognitive Assessment scale for Stroke Patients (CASP), which takes these conditions into consideration and previously demonstrated its superiority over these scales in terms of feasibility. OBJECTIVES: Our goal was to verify the psychometric properties of the (original) French version of the CASP. METHODS: We included 201 patients with a recent first hemispheric stroke and 50 controls. Stroke patients were examined 4 times (visit 1 [V1] to visit 4 [V4]) in the subacute post-stroke phase. The structural validity of the CASP was studied by principal factorial analysis, convergent validity by comparison with several variables including a comprehensive neuropsychological assessment, divergent validity by comparison with the total score between stroke patients and controls, and sub-scores between right and left stroke. Internal consistency, reproducibility and sensitivity to change were assessed. We propose the Minimal Clinically Important Difference (MCID) value and a pathological threshold as well as a threshold to predict cognitive change between V1 and V4. RESULTS: Of the 201 participants included (63% male; mean [SD] age 63 [13] years), CASP data were available for 199/150/133/93 at V1/V2/V3/V4, respectively. CASP has a one-dimensional structure. The hypotheses of convergent/divergent validities were confirmed. Internal consistency was good and reliability excellent. Responsiveness was small to moderate, but the MCID could still be estimated. We discuss the choice of a pathological threshold and a predictive threshold of V1 over V4. CONCLUSIONS: CASP has good psychometric properties for screening cognitive impairment in the subacute post-stroke phase, which is consistent with its Italian and Korean versions. It can be used for patients with severe motor aphasia or left hemispatial neglect but not in case of severe oral comprehension or visual impairment.

Neuropsychology in France.

The purpose of this study was to investigate sociodemographic characteristics, clinical and academic training, and the types of activities engaged in by practicing psychologists specialized in neuropsychology in France. A total of 804 French psychologists specializing in neuropsychology participated in an online-based survey: 90.2% of the participants were women, with a mean age of 32 (range 22-60). In the total sample, 54.2% of the participants worked in the hospital system, 38.2% in the private sector, and 24.9% had a private practice job; and 97.3% engage in evaluation, 74% in rehabilitation, 22.1% in research, and 35.8% in teaching. Clinicians primarily work with individuals with stroke/vascular (56.7%), dementia (53.3%), depression (36.7%), and learning disabilities (34.5%). The top perceived barriers to the field include: lack of willingness to collaborate between professionals (43.7%), lack of professional leaders in the field (40.7%), and lack of clinical training opportunities (24.9%). A total of 68.9% of the clinicians indicate that normative data for their countries do not exist. It is essential for psychologists specialized in neuropsychology in France to establish better-defined guidelines for academic and clinical education, since there is no legal protection of the specialty and given that needs for neuropsychological services are increasing.

Autobiographical memory and the self in a single-case of chronic unilateral spatial neglect.

Unilateral spatial neglect (USN) is mainly defined as a condition affecting perception and the mental representation of the environment. However, nothing is known about its impact on the ability to mentally represent one's past and on personal identity. We addressed these questions in a case of chronic USN, DR, a 59-year-old right-handed woman, who underwent a variety of measures exploring the self and autobiographical memory (AM). DR showed preserved self-images and her AM performance was only preserved when memories were prompted by her own self-images and not by self-unrelated cues. Our findings are discussed in light of the interconnection between the self and AM.
