Symptomatic and Functional recovery: Does symptom severity affect the recovery of executive functioning in people with a psychotic disorder?

Background:Recovery in psychotic disorder patients is a multidimensional concept that can include personal, symptomatic, societal and functional recovery. Here we define Functional Recovery (FR) as recovery or compensation after the loss or impairment of skills in different cognitive functions. Some of the most impaired cognitive functions in psychosis are the executive functions, whose impairment in people with a psychotic disorder can produce problems that are difficult to overcome, partly because treatment often focuses only on Symptomatic Recovery (SR). Although symptom severity may be a risk factor for longstanding impairments of executive functioning, the association is not always found. To date, there has been little research on the association between the 2.MethodThis study is part of the UP’S study, a longitudinal cohort study of patients with a psychotic disorder. The Behaviour Rating Inventory of Executive Functioning Adult version (BRIEF-A) was used to measure FR at baseline and after 1 year. SR was measured using the Positive and Negative Symptom Scale-Remission (PANSS-R), also at baseline and 1 year? At both time points, correlations were computed as cross-sectional analyses. For the longitudinal analysis, the difference scores were used to calculate generalized linear models. Model selection was based on the Wald-Chi square test.Results323 people were included for the baseline assessment of the UP’S study, 163 of whom had completed the T1 follow-up measurement at the time of this study. We found a moderate association between PANSS-R baseline scores and BRIEF-A baseline scores (β=3.76). While there was also an association between the PANSS-R score at baseline and the BRIEF-A difference scores (β=1.67), we found no association between the PANSS-R difference scores and the BRIEF-A differences scores.ConclusionOur finding that less overall symptom severity was associated with 1 year improvement in executive functioning suggests that symptom severity could be a way of improving executive functioning over a year. However, as no link was found within the year between changes in symptoms and changes in executive functioning, it is possible that symptom severity does not have an immediate effect on executive functioning, but that its effect is delayed. This leaves scope for targeted interventions to improve executive functioning, and thus functional recovery

UP's: A cohort study on recovery in psychotic disorder patients : Design protocol

Recovery is a multidimensional concept, including symptomatic, functional, social, as well as personal recovery. The present study aims at exploring psychosocial and biological determinants of personal recovery, and disentangling time-dependent relationships between personal recovery and the other domains of recovery in a sample of people with a psychotic disorder. A cohort study is conducted with a 10-year follow-up. Personal recovery is assessed using the Recovering Quality of Life Questionnaire (ReQoL) and the Individual Recovery Outcomes Counter (I.ROC). Other domains of recovery are assessed by the Positive and Negative Symptom Scale Remission (PANSS-R), the BRIEF-A and the Social Role Participation Questionnaire—Short version (SRPQ) to assess symptomatic, functional and societal recovery, respectively. In addition, multiple biological, psychological, and social determinants are assessed. This study aims to assess the course of personal recovery, and to find determinants and time-dependent relationships with symptomatic, functional and societal recovery in people with a psychotic disorder. Strengths of the study are the large number of participants, long duration of follow-up, multiple assessments over time, extending beyond the treatment trajectory, and the use of a broad range of biological, psychological, and social determinants

Awareness of Sensorimotor Adaptation to Visual Rotations of Different Size

Previous studies on sensorimotor adaptation revealed no awareness of the nature of the perturbation after adaptation to an abrupt 30 degrees rotation of visual feedback or after adaptation to gradually introduced perturbations. Whether the degree of awareness depends on the magnitude of the perturbation, though, has as yet not been tested. Instead of using questionnaires, as was often done in previous work, the present study used a process dissociation procedure to measure awareness and unawareness. A naive, implicit group and a group of subjects using explicit strategies adapted to 20 degrees, 40 degrees and 60 degrees cursor rotations in different adaptation blocks that were each followed by determination of awareness and unawareness indices. The awareness index differed between groups and increased from 20 degrees to 60 degrees adaptation. In contrast, there was no group difference for the unawareness index, but it also depended on the size of the rotation. Early adaptation varied between groups and correlated with awareness: The more awareness a participant had developed the more the person adapted in the beginning of the adaptation block. In addition, there was a significant group difference for savings but it did not correlate with awareness. Our findings suggest that awareness depends on perturbation size and that aware and strategic processes are differentially involved during adaptation and savings. Moreover, the use of the process dissociation procedure opens the opportunity to determine awareness and unawareness indices in future sensorimotor adaptation research
