Project description:BackgroundCognitive remediation (CR) is a psychological therapy, effective in improving cognitive performance and functioning in people with schizophrenia. As the therapy becomes more widely implemented within mental health services its longevity and uptake is likely to depend on its feasibility and acceptability to service users and clinicians.AimsTo assess the feasibility and acceptability of a new strategy-based computerized CR programme (CIRCuiTS) for people with psychosis.MethodFour studies were conducted using mixed methods. Perceptions of attractiveness, comprehensibility, acceptability and usability were assessed using self-report questionnaires in 34 non-clinical participants (study 1), and five people with a schizophrenia diagnosis and three experienced CR therapists (studies 2 and 3). The ease with which pre-specified therapy programmes could be assembled was also assessed by three therapists (Study 2). Finally, the satisfaction of 20 service users with a diagnosis of schizophrenia regarding their experience of using CIRCuiTS in the context of a course of the CR therapy was assessed in a qualitative interview study (study 4).ResultsRatings of perceived attractiveness, comprehensibility, acceptability and usability consistently exceeded pre-set high targets by non-clinical, clinical and therapist participants. Qualitative analysis of satisfaction with CIRCuiTS showed that receiving the therapy was generally seen to be a positive experience, leading to perceptions that cognitive functioning had improved and attempts to incorporate new strategy use into daily activities.ConclusionsCIRCuiTS demonstrates high acceptability and ease of use for both service users with a schizophrenia diagnosis and clinicians.

Project description:Cognitive remediation (CR) research typically addresses internal validity, and few studies consider CR in a real-world context. This study evaluated the fit between the program conditions and treatment model in research and clinical settings, with the goal of informing future research on the contextual challenges associated with the implementation of CR. Data was drawn from an initiative by New York State's Office of Mental Health (OMH), to implement CR programs for adults with Serious Mental Illness (SMI) in 16 state operated outpatient clinics. One of these clinics first became a research site for a CR randomized clinical trial, which allowed for a comparison of the feasibility and acceptability of CR in a research as compared to a clinical setting. RESULTS: The research site averaged almost triple the number of referrals as the clinical sites. Over nine months 46.51% of clinic referrals were enrolled in the CR program whereas 64.29% of research referrals were enrolled. Clinical site utilization averaged 70.53% while research site utilization averaged 90.47%. At the clinical sites, 97% of respondents reported CR was an excellent or good experience. There was high treatment fidelity for program structure and content across sites. CONCLUSIONS: This comparison of CR in clinical and research sites highlights the decrease in referrals, enrollment and utilization that occurs when a program moves from a highly controlled setting to the real world. Still, the acceptability, fill rates and utilization indicated that CR can be successfully implemented in large scale, geographically diverse, publically funded clinic settings.

Project description:With technological advancements and an aging population, there is growing interest in delivering interventions at home. Transcranial Direct Current Stimulation (tDCS) and Cognitive Remediation (CR) as well as Cognitive Training (CT) have been widely studied, but mainly in laboratories or hospitals. Thus, the objectives of this review are to examine feasibility and the interventions components to support the domiciliary administration of tDCS and CR. We performed a systematic search of electronic databases, websites and reference lists of included articles from the first date available until October 31, 2018. Articles included had to meet the following criteria: original work published in English using human subjects, majority of tDCS or CR intervention administered remotely. A total of 39 studies were identified (16 tDCS, 23 CR/CT, 5 using both tDCS & CT). Four studies were single case studies and two were multiple case studies. The remaining 33 studies had a range of 9-135 participants. Five tDCS and nine CR/CT studies were double blind randomized controlled trials. Most studies focused on schizophrenia (8/39) and multiple sclerosis (8/39). Literature examined suggests the feasibility of delivering tDCS or CR/CT remotely with the support of information and communication technologies.

Project description:BACKGROUND:Limited access to Cognitive Training (CT) for people with schizophrenia (SZ) prevents widespread adoption of this intervention. Delivering CT remotely via tablets may increase accessibility, improve scheduling flexibility, and diminish patient burden. METHODS:In this reanalysis of data from a larger trial of CT, we compared two samples of individuals with SZ who chose to complete 40 h of CT either on desktop computers in the laboratory (N = 33) or remotely via iPads (N = 41). We examined attrition rates and adherence to training, and investigated whether remote iPad-based CT and in-person desktop-based CT induced significantly different improvements in cognitive and real-world functioning. RESULTS:The attrition rate was 36.6%. On average, participants completed 3.06 h of CT per week. There were no significant between-group differences in attrition and adherence to CT requirements. Participants who completed iPad-based CT were significantly younger and had lower symptoms at baseline compared to participants who completed CT on the lab desktops. Controlling for age and symptom severity, rANCOVA showed that iPad-based and desktop-based CT similarly and significantly improved verbal learning and problem solving. Main effects of time, at trend level significance, were evident in global cognition, verbal memory, quality of life, and social functioning. All group by time interactions were non-significant except for verbal memory, where iPad users showed greater gains. Within-group effect sizes for changes in outcomes were in the small range. CONCLUSION:Although underpowered and not randomized, this study demonstrates that delivering CT remotely to people with SZ using tablets is feasible and results in retention rates, adherence, and cognitive and functional outcome improvements that are comparable to those observed when CT is delivered in the laboratory. This has important implications in terms of scalability and dissemination of CT. These results require confirmation in larger samples.

Project description:IntroductionGestational weight gain (GWG) and postpartum weight retention (PPWR) are significant, potentially modifiable, contributors to women's future weight and health trajectories. There is a need for feasible and patient-centered (i.e., convenient, remotely-delivered, technology-enhanced, and accessible through the prenatal care setting) behavioural interventions that limit GWG and PPWR. This study tests the feasibility and acceptability of a remotely-delivered behavioural health coaching intervention to limit gestational weight gain and postpartum weight retention.MethodsPregnant women (11-16 weeks gestation) were recruited from two prenatal clinics and randomized to the active intervention or health education comparison group. Completion of the program was monitored and perceived helpfulness was rated (0-100).ResultsTwenty-six women were randomized (n = 13 per arm; mean age = 31.6 years, SD = 3.6; mean BMI = 26.7 kg/m2, SD = 7.4). Participants completed a median of 18 coaching calls and 16/19 learning activities during pregnancy, and a median of 6 calls and 5/6 learning activities postpartum. They logged weights at least once/week for a median of 36/38 expected weeks and tracked daily calories and exercise for a median of 154/266 days and 72/266 days, respectively. Median (Q1, Q3) helpfulness ratings of the program during pregnancy were 80 (64, 91) and 62 (50, 81) postpartum; helpfulness ratings of coaching calls were 85 (58, 98). At 37 weeks gestation, 77% of participants achieved IOM weight gain recommendations compared to 54% in the comparison group.ConclusionsThis study provides evidence for the feasibility and acceptability of a remotely-delivered behavioural weight control intervention in pregnancy and postpartum.

Project description:BACKGROUND:Childhood cancer survivors frequently develop working memory (WM) deficits as a result of disease and treatment. Medication-based and therapist-delivered interventions are promising but have limitations. Computerized interventions completed at home may be more appealing for survivors. We evaluated the feasibility and acceptability of a remotely administered, computerized WM intervention (Cogmed) for pediatric cancer survivors using a single-blind, randomized, wait-list control design. METHODS:Of 80 qualifying patients, 12 were excluded or declined to participate. Participants randomized to intervention (n = 34/68) included survivors of childhood brain tumors (32%) or acute lymphoblastic leukemia (ALL; 68%) between the ages of 8 and 16 years ([Formula: see text] = 12.2) who were at least 1 year post therapy ([Formula: see text] = 5.0). The majority of brain tumor participants were treated with cranial radiation therapy (72.7%), whereas most of the ALL participants were treated with chemotherapy only (87%). Participants completed 25 WM training sessions over 5-9 weeks at home with weekly phone-based coaching. RESULTS:Participants lived in 16 states. Compliance was strong, with 30 of the 34 participants (88%) completing intervention. Almost all participants completed pre- and postintervention neuroimaging exams (91% and 93%, respectively). Families had the necessary skills to utilize the computer program successfully. Caregivers reported they were generally able to find time to complete training (63%), viewed training as beneficial (70%), and would recommend this intervention to others (93%). CONCLUSIONS:Cogmed is a feasible and acceptable intervention for childhood cancer survivors. It is a viable option for survivors who do not live in close proximity to cancer care centers. Efficacy and neural correlates of change are currently being evaluated.

Project description:Standard approaches to cognitive remediation can suffer from limited skill transferability to patients' life. Complex virtual environments (VEs) enable us to create ecologically valid remediation scenarios while preserving laboratory conditions. Nevertheless, the feasibility and efficacy of these programs in psychiatric patients are still unknown. Our aim was to compare the feasibility and efficacy of a novel rehabilitation program, designed in complex VEs, with standard paper-pencil treatment in patients with schizophrenia and major depressive disorder. We recruited 35 participants to complete a VE rehabilitation program and standard treatment in a crossover pilot study. Twenty-eight participants completed at least one program, 22 were diagnosed with schizophrenia and 6 with major depressive disorder. Participant's performance in the representative VE training task significantly improved in terms of maximum achieved difficulty (p ≤ 0.001), speed (p < 0.001) and efficacy (p ≤ 0.001) but not in item performance measure. Neither the standard treatment nor the VE program led to improvement in standardized cognitive measures. Participants perceived both programs as enjoyable and beneficial. The refusal rate was higher in the VE program (8.6%) than in the standard treatment (0%). But in general, the VE program was well-accepted by the psychiatric patients and it required minimal involvement of the clinician due to automatic difficulty level adjustment and performance recording. However, the VE program did not prove to be effective in improving cognitive performance in the standardized measures.

Project description:d-Cycloserine (DCS) has been shown to enhance memory and, in a previous trial, once-weekly DCS improved negative symptoms in schizophrenia subjects. We hypothesized that DCS combined with a cognitive remediation (CR) program would improve memory of a practiced auditory discrimination task and that gains would generalize to performance on unpracticed cognitive tasks. Stable, medicated adult schizophrenia outpatients participated in the Brain Fitness CR program 3-5 times per week for 8weeks. Subjects were randomly assigned to once-weekly adjunctive treatment with DCS (50mg) or placebo administered before the first session each week. Primary outcomes were performance on an auditory discrimination task, the MATRICS cognitive battery composite score and the Scale for the Assessment of Negative Symptoms (SANS) total score. 36 subjects received study drug and 32 completed the trial (average number of CR sessions=26.1). Performance on the practiced auditory discrimination task significantly improved in the DCS group compared to the placebo group. DCS was also associated with significantly greater negative symptom improvement for subjects symptomatic at baseline (SANS score ?20). However, improvement on the MATRICS battery was observed only in the placebo group. Considered with previous results, these findings suggest that DCS augments CR and alleviates negative symptoms in schizophrenia patients. However, further work is needed to evaluate whether CR gains achieved with DCS can generalize to other unpracticed cognitive tasks.

Project description:A functional polymorphism of the catechol-O-methyltransferase (COMT) gene (Val158Met) partially appears to influence cognitive performance in schizophrenia subjects and healthy controls by modulating prefrontal dopaminergic activity. This study evaluated the association of the COMT Val108/158 Met genotype with response to computerized neurocognitive remediation (CRT).145 subjects with DSM-IV-TR schizophrenia or schizoaffective disorder were genotyped via saliva sampling. Subjects were evaluated on neurocognitive assessments (MATRICS) and clinical symptoms (PANSS) at baseline and endpoint after 12weeks of CRT. "Improvement" was defined as ?67% of cognitive domains (?4) showing performance increases. If ?67% (?2) of domains improved, the change was defined as "minimal improvement." A general linear model was conducted for change of each cognitive domain.Of 145 subjects, data from 138 subjects were usable. Distribution of COMT genotype: Met/Met: 28 (20.29%), Val/Met: 61 (44.20%), and Val/Val: 49 (35.51%). No significant differences were seen among genotype groups at baseline or across genotype group for "Improvement" vs. "Minimal Improvement." GLM analysis showed significant differences in Verbal Learning (p=0.003), Visual Learning (p=0.014) and Attention/Vigilance (p=0.011) favoring Met/Met and Val/Met groups.The low activity Met allele (Met/Met; Val/Met) was associated with significantly greater improvements in the MATRICS domains of Verbal Learning, Visual Learning and Attention/Vigilance after CRT.

Project description:Cognitive impairment in schizophrenia is often severe, enduring, and contributes significantly to chronic disability. A standardized platform for identifying cognitive impairments and measuring treatment effects in cognition is a critical aspect of comprehensive evaluation and treatment for individuals with schizophrenia. In this project, we developed and tested a suite of ten web-based, neuroscience-informed cognitive assessments that are designed to enable the interpretation of specific deficits that could signal that an individual is experiencing cognitive difficulties. The assessment suite assays speed of processing, sustained attention, executive functioning, learning and socio-affective processing in the auditory and visual modalities. We have obtained data from 283 healthy individuals who were recruited online and 104 individuals with schizophrenia who also completed formal neuropsychological testing. Our data show that the assessments 1) are acceptable and tolerable to users, with successful completion in an average of under 40 min; 2) reliably measure the distinct theoretical cognitive constructs they were designed to assess; 3) can discriminate schizophrenia patients from healthy controls with a fair degree of accuracy (AUROC > 0.70); and 4) have promising construct, convergent, and external validity. Further optimization and validation work is in progress to finalize the evaluation process prior to promoting the dissemination of these assessments in real-world settings.
