Associations between learning principles of cognitive remediation and cognitive and vocational outcomes in early psychosis-an exploratory analysis of RCT data.

Background: Most cognitive remediation (CR) programs are based on multiple scientific learning principles. The role of those learning principles in the beneficial effects of CR is poorly understood. A better understanding of such underlying mechanisms is important to further tailor the intervention and to learn about optimal contexts.Method: An explorative secondary analysis was conducted of data from a randomized controlled trial (RCT) comparing the effects of Individual Placement and Support (IPS) with and without CR. The present study evaluated how CR learning principles of "massed practice," "errorless learning," "strategy use" and "therapist contribution" (therapist fidelity) were associated with cognitive and vocational outcomes within 26 participants in this RCT who were treatment exposed.Results: Cognitive gains after CR were positively associated with "massed practice" and "errorless learning." Negative associations were found with "strategy use" and "therapist fidelity." No direct relationship was found between CR principles and vocational outcomes.Conclusions: Results tentatively suggest that CR is most effective and efficient with a good balance between sufficient intensity, of more than 200 tasks, and a limited duration of the training up to 20 h, using tasks that remain both challenging and rewarding, being applied in a context that facilitates real-life practice.

Effects of IPS plus cognitive remediation in early psychosis: 18-month functioning outcomes of a randomized controlled trial.

BACKGROUND: After a first episode of psychosis, cognitive impairments present an important barrier to successful (re-)entry into work and education. We assessed whether cognitive remediation (CR) as an add-on to Individual Placement and Support (IPS) can improve participation in regular employment and education. METHOD: Participants with early psychosis (N = 73) were randomly assigned to receive IPS supplemented with computerized CR, or IPS plus an active control intervention (computer games). The primary outcome was the number of hours spent in competitive employment or regular education, which was assessed every month during the 18-month study period. Secondary outcomes included employment rate, cognitive functioning, mental health (assessed at baseline, 6 and 18 months), and job duration (assessed after 18 months). Both patients and assessors were blind to treatment. RESULTS: Participants receiving IPS + CR showed greater improvement of competitive employment over time in terms of hours worked (during follow-up period: 38.5 vs. 19.6 h, B = 2.94; Wald χ2 = 5.39; P = .02) and employment rate (at T2: 62.1% vs. 25.9%, χ 2 = 7.39; df = 1; P = .008), compared with the IPS + control group, particularly in the longer term. The number of hours spent in regular education was lower in the IPS + CR group, with more participants having ended education for a positive reason. There was a significant beneficial effect of adjunctive CR for executive functioning, subjective cognitive functioning, and empowerment. CONCLUSIONS: Augmenting IPS with CR has a significant impact on competitive employment in people with early psychosis, with beneficial effects being more pronounced after 18 months.

Implementing Evidence-Based Interventions to Improve Vocational Recovery in Early Psychosis: A Quality-Improvement Report.

OBJECTIVE: After young adults experience a first episode of psychosis, many express a need for help with education and employment. A quality improvement collaborative (QIC) launched in the Netherlands aimed to reinforce vocational recovery by improving participation in education and employment and by enhancing cognitive skills and self-management. This study examined methods used to implement interventions, barriers and facilitators, and implementation outcomes (fidelity, uptake, and availability). METHODS: The Breakthrough Series was the model for change. Three evidence-based interventions were implemented to achieve targeted goals: individual placement and support (IPS), cognitive remediation, and shared decision making. Fidelity scores were obtained with fidelity scales. RESULTS: Eighty-five professionals and 332 patients representing 14 teams treating patients with early psychosis were included in the 24-month QIC. Of this group, 252 patients participated in IPS, 52 in cognitive remediation, and 39 in shared decision making. By month 22, teams attained moderate-to-high mean fidelity scores, with an average of 3.2 on a 4-point scale for cognitive remediation, 3.7 on a 5-point scale for IPS, and 4.9 on a 6-point scale for shared decision making. CONCLUSIONS: Over 24 months, use of a Breakthrough QIC to implement three interventions aimed at improving vocational recovery in teams delivering services for early psychosis yielded mixed results in terms of uptake and availability and moderate-to-high results in terms of fidelity. When implementing these types of interventions in this population, a multifaceted implementation model and a focused testing phase for computerized interventions appear needed, preferably with a maximum of two interventions implemented simultaneously.

Improving cognition in severe mental illness by combining cognitive remediation and transcranial direct current stimulation: study protocol for a pragmatic randomized controlled pilot trial (HEADDSET).

BACKGROUND: A fundamental challenge for many people with severe mental illness (SMI) is how to deal with cognitive impairments. Cognitive impairments are common in this population and limit daily functioning. Moreover, neural plasticity in people with SMI appears to be reduced, a factor that might hinder newly learned cognitive skills to sustain. The objective of this pilot trial is to investigate the effects of cognitive remediation (CR) on cognitive and daily functioning in people dependent on residential settings. In addition, transcranial direct current stimulation (tDCS) is used to promote neural plasticity. It is expected that the addition of tDCS can enhance learning and will result in longer-lasting improvements in cognitive and daily functioning. METHODS: This is a pragmatic, triple-blinded, randomized, sham-controlled, pilot trial following a non-concurrent multiple baseline design with the participants serving as their own control. We will compare (1) CR to treatment as usual, (2) active/sham tDCS+CR to treatment as usual, and (3) active tDCS+CR to sham tDCS+CR. Clinical relevance, feasibility, and acceptability of the use of CR and tDCS will be evaluated. We will recruit 26 service users aged 18 years or older, with a SMI and dependent on residential facilities. After a 16-week waiting period (treatment as usual), which will serve as a within-subject control condition, participants will be randomized to 16 weeks of twice weekly CR combined with active (N = 13) or sham tDCS (N = 13). Cognitive, functional, and clinical outcome assessments will be performed at baseline, after the control (waiting) period, directly after treatment, and 6-months post-treatment. DISCUSSION: The addition of cognitive interventions to treatment as usual may lead to long-lasting improvements in the cognitive and daily functioning of service users dependent on residential facilities. This pilot trial will evaluate whether CR on its own or in combination with tDCS can be a clinically relevant addition to further enhance recovery. In case the results indicate that cognitive performance can be improved with CR, and whether or not tDCS will lead to additional improvement, this pilot trial will be extended to a large randomized multicenter study.

Researcher allegiance in research on psychosocial interventions: meta-research study protocol and pilot study.

INTRODUCTION: One potential source of bias in randomised clinical trials of psychological interventions is researcher allegiance (RA). The operationalisation of RA differs strongly across studies, and there is not a generally accepted method of operationalising or measuring it. Furthermore, it remains unclear as to how RA affects the outcomes of trials and if it results in better outcomes for a preferred intervention. The aim of this project is to develop and validate a scale that accurately identifies RA, contribute to the understanding of the impact that RA has in a research setting and to make recommendations for addressing RA in practice. METHODS AND ANALYSIS: A scale will first be developed and validated to measure RA in psychotherapy trials. The scale will be validated by surveying authors of psychotherapy trials to assess their opinions, beliefs and preferences of psychotherapy interventions. Furthermore, the scale will be validated for use outside the field of psychotherapy. The validated checklist will then be used to examine two potential mechanisms of how RA may affect outcomes of interventions: publication bias (by assessing grants) and risk of bias (RoB). Finally, recommendations will be developed, and a feasibility study will be conducted at a national mental health agency in The Netherlands. Main analyses comprise inter-rater reliability of checklist items, correlations to examine the relationship between checklist items and author survey (convergent validity) as well as checklist items and trial outcomes and multivariate meta-regression techniques to assess potential mechanisms of how allegiance affects trial outcomes (publication bias and RoB). ETHICS AND DISSEMINATION: This study has been reviewed and approved by the Scientific and Ethical Review Board (VCWE) at the Vrije Universiteit Amsterdam. Study result and advancements will also be published on the Open Science Framework. Furthermore, main findings will be disseminated through articles in international peer-reviewed open access journals. Results and recommendations will be communicated to the Cochrane Collaboration, the Campbell Collaboration and other funding agencies.

The effect of rehabilitation combined with cognitive remediation on functioning in persons with severe mental illness: systematic review and meta-analysis.

BACKGROUND: Psychiatric rehabilitation (PR) can improve functioning in people with severe mental illness (SMI), but outcomes are still suboptimal. Cognitive impairments have severe implications for functioning and might reduce the effects of PR. It has been demonstrated that performance in cognitive tests can be improved by cognitive remediation (CR). However, there is no consistent evidence that CR as a stand-alone intervention leads to improvements in real-life functioning. The present study investigated whether a combination of PR and CR enhances the effect of a stand-alone PR or CR intervention on separate domains of functioning. METHOD: A meta-analysis of randomized controlled trials of PR combined with CR in people with SMI was conducted, reporting on functioning outcomes. A multivariate meta-regression analysis was carried out to evaluate moderator effects. RESULTS: The meta-analysis included 23 studies with 1819 patients. Enhancing PR with CR had significant beneficial effects on vocational outcomes (e.g. employment rate: SMD = 0.41), and social skills (SMD = 0.24). No significant effects were found on relationships and outcomes of community functioning. Effects on vocational outcomes were moderated by years of education, intensity of the intervention, type of CR approach and integration of treatment goals for PR and CR. Type of PR was no significant moderator. CONCLUSIONS: Augmenting PR by adding cognitive training can improve vocational and social functioning in patients with SMI more than a stand-alone PR intervention. First indications exist that a synergetic mechanism also works the other way around, with beneficial effects of the combined intervention compared with a stand-alone CR intervention.

The multidisciplinary depression guideline for children and adolescents: an implementation study.

It is important that depressed patients receive adequate and safe care as described in clinical guidelines. The aim of this study was to evaluate the implementation of the Dutch depression guideline for children and adolescents, and to identify factors that were associated with the uptake of the guideline recommendations. The study took place in specialised child and adolescent mental healthcare. An implementation project was initiated to enhance the implementation of the guideline. An evaluation study was performed alongside the implementation project, using structured registration forms and interviews with healthcare professionals. Six multidisciplinary teams participated in the implementation study. The records of 655 patients were analysed. After 1 year, 72% of all eligible patients had been screened for depression and 38% were diagnosed with the use of a diagnostic instrument. The severity of the depression was assessed in 77% of the patients during the diagnostic process, and 41% of the patients received the recommended intervention based on the depression severity. Of the patients that received antidepressants, 25% received weekly checks for suicidal thoughts in the first 6 weeks. Monitoring of the patients' response was recorded in 32% of the patients. A wide range of factors were perceived to influence the uptake of guideline recommendations, e.g. the availability of capable professionals, available time, electronic tools and reminders, and the professionals' skills and attitudes. With the involvement of the teams, recommendations were provided for nationwide implementation of the guideline. In conclusion, a systematic implementation programme using stepped care principles for the allocation of depression interventions seems successful, but there remains room for further improvement.

Bridging the science-to-service gap in schizophrenia care in the Netherlands: the Schizophrenia Quality Improvement Collaborative.

OBJECTIVE: Many patients with schizophrenia are not treated in line with evidence-based guidelines. This study examines the large-scale implementation of the National Multidisciplinary Guideline for schizophrenia in the Netherlands. DESIGN: /st> Observational, prospective study, with repeated measurement. SETTING: Thirty mental healthcare teams in different regions of the Netherlands. PARTICIPANTS: Three hundred and fifty-nine clinicians with different professional backgrounds and 1489 patients suffering from schizophrenia. INTERVENTION(S): Six evidence-based interventions for schizophrenia were implemented, in the context of a quality improvement collaborative: assertive community treatment (ACT) or its adapted version functional assertive community treatment (FACT), cognitive behavioural therapy, psycho-education, family interventions, individual placement support and pharmacotherapy. MAIN OUTCOME MEASURE(S): Professional performance, social functioning and relapse rates. RESULTS: Improved professional performance, in line with guidelines. Availability of (F)ACT improved from 23 to 60%. Individual Placement Support improved from 20 to 53%. Complete care plans were composed for 38% of the patients and routine outcome monitoring was introduced in most teams. Social functioning improved slightly (HoNOS mean: from 6.2 to 5.6). Relapse rates did not improve during the course of the study. CONCLUSIONS: An intensive implementation programme can result in an improved delivery of evidence-based care, increased continuity of care and slightly improved outcomes for individuals with schizophrenia. More rigorous research designs have to confirm these findings.

Early psychosocial interventions after disasters, terrorism, and other shocking events: guideline development.

Although most victims of disasters, terrorism, or other shocking events recover on their own, a sizable amount of these victims develops long-term disaster-related problems. These victims should receive timely and appropriate psychosocial help. This article describes the development of guidelines on psychosocial interventions during the first 6 weeks after a major incident. Scientific literature, expert opinions, and consensus among relevant parties in the clinical field were used to formulate the recommendations. Early screening, a supportive context, early preventive and curative psychosocial interventions, and the organization of interventions are covered. The implications for the clinical field and future research are discussed. It is concluded that the international knowledge base provides valuable input for the development of national guidelines. However, the successful implementation of such guidelines can take place only if they are legitimated and accepted by local key actors and operational target groups. Their involvement during the development process is vital.

An intervention program for ADHD in patients with substance use disorders: preliminary results of a field trial.

The comorbidity of attention deficit hyperactivity disorder (ADHD) is frequently not well recognized in substance abuse treatment institutions in The Netherlands. As a consequence, patients with substance use disorder (SUD) and ADHD often receive suboptimal treatment. To prevent every treatment center from having to invent its own diagnostic procedure and intervention for ADHD, a national working group was established. This group developed an intervention program for the screening, diagnosis, and treatment of ADHD in patients with SUD. This article describes the development and content of this intervention program. An important part of this development was testing the intervention program in two addiction treatment centers in The Netherlands. Systematic screening of ADHD was part of the test. A self-report questionnaire was used. Subjects with positive screening results were referred for the diagnostic procedure. Nine hundred twenty-eight screenings were performed: 207 screened positive, 115 came for further diagnostics, and 65 were ultimately diagnosed with ADHD.

Alcohol hangover effects on memory functioning and vigilance performance after an evening of binge drinking.

The impairing effects on memory functioning after acute alcohol intoxication in healthy volunteers and after chronic use in alcoholics are well established. However, research determining the next-morning effects of a single episode of binge drinking on memory functioning is scarce. A total of 48 healthy volunteers participated in a single-blind study comprising an evening (baseline) session, followed by a treatment administration (ethanol 1.4 g/kg or placebo), and a morning session. Memory was tested with a word-learning test (including immediate and delayed recall, and recognition). Further, a 45-min Mackworth clock test for measuring vigilance was included (parameters: number of hits and false alarms) and subjective alertness was assessed, to infer whether word-learning test findings reflect sedation or specific memory impairments. Delayed recall in the morning session was significantly worse in the alcohol group when compared to the placebo group (F(1,42)=6.0, p<0.02). In contrast, immediate recall and recognition were unimpaired in the alcohol group. In the morning session, relative to the placebo group, subjective alertness was significantly reduced in the alcohol group before and after the tests (F(1,44)=8.7, p<0.005; F(1,44)=13.3, p&<0.001, respectively). However, in the Mackworth clock test, the alcohol group and placebo group did not differ significantly in the morning session. The specific findings of impaired delayed recall show that memory retrieval processes are significantly impaired during alcohol hangover. Vigilance performance was not significantly affected, indicating that this memory impairment does not reflect sedation.
