Assessment of executive functions in patients with obsessive compulsive disorder by NeuroVR.

Executive functions are often impaired in obsessive-compulsive disorder (OCD). We used a Virtual Reality version of the Multiple Errand Test (VMET) - developed dusing the free NeuroVR software (http://www.neurovr.org) - to evaluate the executive functions in daily life in 10 OCD patients and 10 controls. It is performed in a shopping setting where there are items to be bought and information to be obtained. The execution time for the whole task was higher in patients with OCD compared to controls, suggesting that patients with OCD need more time in planning than controls. The same difference was found in the partial errors during the task. Furthermore, the mean rank for and for interpretation failures is higher for controls, while the values of divided attention and the of self correction seems to be lower in controls. We think that obsessive patients tend to work with greater diligence and observance of rules than controls. In conclusion, these results provide initial support for the feasibility of VMET as assessment tool of executive functions. Specifically, the significant correlation found between the VMET and the neuropsychological battery support the ecological validity of VMET as an instrument for the evaluation of executive functions in patients with OCD.

Cognitive thought diary in supportive psychology for people undergoing radiotherapy: a feasibility study.

BACKGROUND: Radiation therapy (RT) has become one of the most widely-used and efficient treatments for cancer; nevertheless, people who undergo radiotherapy suffer the physical and psychological consequences of this stressful treatment, in addition to the psychosocial distress related to cancer. however, a radiotherapy Unit is often a place where several patients crowd in from various hospitals with restricted timetables and, for logistic reasons, it is not easy to provide regular psychological sessions for each one. It is important to find a setting that allows us the involvement of the largest number of patients referred to the unit. in this study, we aimed to evaluate the feasibility and the effect of a brief intervention of cognitive-oriented diary on the quality of life, anxiety and depressive symptoms of patients undergoing radiotherapy (rt), compared to a control group. MethODs: the sample was constituted of 68 experimental subjects and 78 controls, treated with rt. Both groups were assessed with the toronto alexithymia scale (tas-20), the hamilton anxiety and Depression scale (haDs) and the eOrtc-QLQ at the beginning and at the end of their rt. experimental subjects were instructed to report emotions and thoughts before attending the rt sessions in a thought diary. resULts: the experimental group showed a good adherence to the diary, a reduction in mean scores of anxiety (P<0.001), depression (P<0.001), and alexithymia (P<0.001) together with an ameliorative effect on quality of life (P<0.014), compared to control group. CONCLUSIONS: We observed a reduction in alexithymia scores in the experimental group, together with a significant reduction in anxiety and depression symptoms and an improvement in quality of life, with a moderator role of social disparity in treatment adherence. Our outcomes suggest the opportunity to consider the diary an affordable and effective device for psychologists operating in rt units, able to be extended to the majority of patients, in a simple and replicable setting.

Cognitive Assessment of OCD Patients: NeuroVR vs Neuropsychological Test.

This study aimed to evaluate the reliability and validity of the Neuro-Virtual Reality as tool for the neuropsychological assessment in OCD patients. We used the neuropsychological battery and a virtual version of the Multiple Errand Test (V-MET), developed using the NeuroVR software, in order to evaluate the executive functions, the ability to plan ahead on complex problem solving tasks in daily life in 30 obsessive compulsive disorder (OCD) patients and 30 healthy controls. The results showed the presence of difficulties of OCD patients: lower levels of divided attention and higher levels of errors; higher mean rank of inefficiencies, interpretation failures and rule breaks and longer time of execution of the whole task. By contrast, controls have higher level of efficiency and better performance. In addition, a significant correlation was found between the V-MET and the neuropsychological battery which confirms and supports the ecological validity of neurocognitive assessment through NeuroVirtual Reality.

Psychometric assessment using classic neuropsychological and virtual reality based test: A study in obsessive-compulsive disorder (OCD) and schizophrenic patients

Assessment of neurocognitive functioning is a critical task in clinical settings. In many disorders, cognitive impairment precedes the onset of behavioral symptoms, and cognitive decline is a major factor contributing to functional disability. The purpose of the current study was to evaluate the executive functions by comparing the evaluations obtained using a neuropsychological battery with the one obtained using the virtual reality version of the Multiple Errands Test (V-MET). The study population included three groups: 10 patients affected by Obsessive Compulsive Disorder (OCD); 10 Schizophrenic patients; 10 healthy Controls. The results identified executive problems in clinical samples. By contrast, controls have higher level of efficiency and better performance. The correlation across the two assessment support the validity of V-Met, as a neurocognitive assessment.

Decision Making and Cognitive Behavioral Flexibility in a OCD Sample: a Study in a Virtual Environment.

Neuropsychological disorders are common in Obsessive-Compulsive Disorder (OCD) patients. Executive functions, verbal fluency and verbal memory, shifting attention from one aspect of stimuli to others, mental flexibility, engaging in executive planning and decision making, are the most involved cognitive domains. We focus on two aspects of neuropsychological function: decision making and cognitive behavioral flexibility, assessed through a virtual version of the Multiple Errand Test (V-MET), developed using the NeuroVR software. Thirty OCD patients were compared with thirty matched control subjects. The results showed the presence of difficulties in OCD patients with tasks where the goal is not clear, the information is incomplete or the parameters are ill-defined.
