  The study follows an intellectually superior patient from initial subjective memory complaints to MCI and dementia over 21 years. Primary memory measures, process- and reliable change-measures from 12 assessments with the California Verbal Learning Test (CVLT) were analyzed as well as experimental measures of retrieval and Recency-Ratio (Rr) combining traditional recency measures with selective retrieval impairments of recency items.Recency change preceded normatively impaired memory by four years, and retention percentage by two years. Rr indicated risk for MCI conversion 13 years prior to receiving that diagnosis, and is an interesting measure for early detection of dementia in CVLT.

  Background Exercise may improve cardiorespiratory fitness in people with schizophrenia, however, possible condition-specific cardiorespiratory disadvantages, a scarcity of methodologically sound studies, and conflicting results raise questions about the effect of exercise on maximal oxygen uptake (VO2max) in this group. The primary aim of this study, therefore, was to investigate the effect of high-intensity interval training on VO2max in people with schizophrenia. Second, we sought to determine whether the intervention would have an effect on general physical activity (PA) level and body composition. Methods Eighty-two patients with schizophrenia were randomly assigned to supervised high-intensity interval training or computer gaming skills training, performed twice a week for 12 weeks. Oxygen uptake was measured directly, during a maximum exercise session on a treadmill. PA level were assessed using ActiGraph accelerometer, and body composition was assessed by bioelectrical impedance. Differences between groups were assessed by analysis of variance using a univariate general linear model. Results There were no significant differences between the groups on any of the cardiorespiratory variables neither at baseline nor after the program. There were also no significant within-group differences in any of the cardiorespiratory fitness variables between the baseline and post-program time points, despite that 61% of the participants performing high-intensity interval training showed a significant increase in workload on the treadmill. However, 47% of the participants in the high-intensity interval training group had a ≥ 5% increase in VO2max. Participants supervised by mental health care providers with PA competence (e.g. rehabilitation center staff, sport scientist, physical trainer) had a much larger increase in VO2max compared to participants supervised by mental health workers without such competence, and when adding PA competence to the model, the intervention group increased VO2max significantly compared to the comparison group. The intervention had no significant effect on PA level or body composition. Conclusions The intervention did not improve VO2max, PA level or body composition but succeeded in increasing workload on the treadmill. With regard to VO2max, approximately half of the patients may be considered responders.

  There is a need for treatments targeting neurocognitive dysfunctions in schizophrenia. The aim of this study was to investigate the neurocognitive effect of aerobic high-intensity interval training (HIIT). A comparison group performed sport simulating active video gaming (AVG). We anticipated that HIIT would improve neurocognition beyond any effect of AVG, due to engagement in higher intensity cardiorespiratory demands. Recent research on the beneficial neurocognitive effect of AVG challenges this expectation but added new relevance to comparing the two interventions. This is an observer-blinded randomized controlled trial. Eighty-two outpatients diagnosed with schizophrenia were allocated to HIIT (n = 43) or AVG (n = 39). Both groups received two supervised sessions per week for 12 weeks. The attrition rate was 31%, and 65% of the participants were defined as protocol compliant study completers. Intention-to-treat analyses showed significant improvements in the neurocognitive composite score from baseline to post-intervention and from baseline to 4 months follow-up in the total sample. The same pattern of results was found in several subdomains. Contrary to our hypothesis, we found no interaction effects of time and group, indicating equal effects in both groups. Separate within-group analysis unexpectedly showed trends of differential effects in the learning domain, as HIIT showed post-intervention improvement in verbal but not visual learning, while AVG showed improvement in visual but not verbal learning. HIIT and AVG improve neurocognition equally, suggesting that both interventions may be applied to target neurocognition in schizophrenia. Future research should investigate trends towards possible differential effects of exercise modes on neurocognitive subdomains

  Wechsler Intelligence Scale for Children – Fifth Edition (WISC-V) ble publisert i USA i 2014 og den norske versjonen kom i 2017. Norsk og internasjonal rettighetshaver er Pearson Assessment. Oversettelsesarbeidet, inkludert kulturell tilpasning, ble gjennomført av Pearson Assessment med hjelp fra klinisk ekspertise i Norge, Danmark og Sverige. WISC-V er en individuelt administrert test av intellektuelle evner hos barn og ungdom i alderen 6:0-16:11 år. Testen består av 15 deltester, ti primære og fem sekundære deltester. Testtiden er beregnet til 45–80 minutter, avhengig av antall deltester og barnets alder. Psykologer og fagpersoner med mastergrad i pedagogikk med fordypning i pedagogisk-psykologisk rådgivning eller spesialpedagogikk fra UiO er kvalifisert til å kjøpe testen. For personer med mastergrad i pedagogikk eller psykologi fra andre læresteder er det et eget sertifiseringsprogram. Søket førte til 1119 norske, respektive 1865 svenske og danske treff. Ingen av treffene var relevante. Manualens skandinaviske normering er det eneste grunnlaget for vurdering av testens psykometriske egenskaper. Normer for aldersgrupper, validitet og reliabilitet, samt gjennomsnittsskårer for barn med lett intellektuell funksjonsnedsettelse og for særlig evnerike barn, ble rapportert i manualen. Normeringsutvalget bestod av 660 barn fra 6:0 til 16:11. Resultatene ble presentert som skalerte skårer fra 1 til 19, med et gjennomsnitt på ti og et standardavvik på tre. Indeksskårer ble konstruert med et gjennomsnitt på 100, et standardavvik på 15 og et skåreintervall på 45–155, respektive 40–160. Reliabilitetskoeffisienter (indre konsistens) på deltestnivå og indeksnivå var fra gode til utmerkede. Goodness-of-fit-analyse i forbindelse med konfirmatorisk faktoranalyse ga CFI 0,97-0,98 og RMSEA 0,05 for valgt femfaktormodell. Mønsteret av interkorrelasjoner mellom deltest, prosesskår og indeks viser store likheter med resultatene fra den amerikanske standardiseringen. Korrigerte rangkorrelasjonene for FSIQ og på indeksnivå mellom WISC-V og WISC-IV er høye (0,67-0,91). Kriterierelatert validitet som predikerer både intellektuell funksjonsnedsettelse og særlige evner var dårligere enn forventet og spesielt for gruppen særlig evnerike barn. Det er behov for mer dokumentasjon av måleegenskapene i en klinisk skandinavisk kontekst. Basert på dokumentasjonen som finnes fremstår WISC-V i hovedsak som et reliabelt instrument for vurdering av evnenivå og kognitiv profil. Foreliggende data er utilstrekkelige til å vurdere hvorvidt WISC-V også er et valid instrument for vurdering av kognitiv profil. Klinisk profiltolkning bør dermed gjøres med forsiktighet.

  Are people with superior intelligence also superior in interpreting the emotions of others? Some studies find that an underlying g-factor links all mental processes leading to an expectation of a positive answer to the question, while other studies find that there is a cost to giftedness. No previous study have tested social cognition among highly gifted, or the Mensa society specifically. The study measures emotion recognition in 63 members of the Norwegian Mensa and 101 community controls. The Mensa group had a higher total score on the EmoBio test and was specifically better at differentiating the anger emotion, otherwise hypothesized to be mediated by subcortical processes. There was no difference in heterogeneity between the groups, contrary to the expectation of an autistic subgroup in Mensa. The study indicate that the positive manifold extends also to social cognition, and runs counter to the concept of a cost to giftedness.

  Objective: The aim of this study was to examine whether reaction time parameters in adult patients with ADHD could predict their response to methylphenidate (MPH). Method: Previously unmedicated patients (N = 123) were administered the Conners’ Continuous Performance Test II (CPT II) at baseline and after 6 weeks of treatment with immediate-release MPH. In addition to traditional CPT measures, we extracted intraindividual raw data and analyzed time series using linear and nonlinear mathematical models. Results: Clinical responders, assessed with the Clinical Global Impression-Improvement scale, showed significant normalization of target failures, reduced variability and skewness, and increased complexity of reaction time series after 6 weeks of treatment, while nonresponders showed no significant changes. Prior to treatment, responders had significantly higher variability and skewness, combined with lower complexity, compared with nonresponders. Conclusion: These results show that the CPT test is useful in the evaluation of treatment response to MPH.

  Objective: We investigated whether levels of current physical activity (PA) contribute to the established relationship between cardiorespiratory fitness (CRF) and cognition in schizophrenia and whether brain-derived neurotrophic factor (BDNF) or its precursor proBDNF mediates this relationship. Method: Sixty-one outpatients with schizophrenia spectrum disorders participated. Neurocognition was assessed with the Wechsler Adult Intelligence Scale (WAIS) and nine subtests from the MATRICS battery comprising a neurocognitive composite score (NCS). CRF was assessed with peak oxygen uptake (VO2peak) measured directly during a maximum exercise test. Current PA levels were objectively assessed by an accelerometer worn for four consecutive days. BDNF and proBDNF were measured in fasting blood. Four serial parallel mediation analyses and two additional parallel mediation analyses were conducted, while controlling for age and sex at all levels. Results: No direct effects were found between PA measures and WAIS or NCS. No significant mediating effects of CRF or BDNF/proBDNF were detected. Conclusion: The results do not support the hypothesis that PA contributes to the naturally occurring relationship between CRF and cognition in schizophrenia or the hypothesis that BDNF or proBDNF mediates this relationship. The results arguably support the assumption that the association between CRF and cognition in schizophrenia is established developmentally early.

  Purpose The aim of this study was to assess short and long-term effectiveness of brief coping-focused psychotherapy (Brief-PsT) compared with short-term psychotherapy (Short-PsT) on work-participation (WP) and mental health. Both treatments were preceded by group education. Methods All participants were on, or at risk of, sick leave due to common mental complaints. Patients were selected for inclusion in this study based on levels of self-reported symptoms (‘some’ or ‘seriously affected’) of anxiety and depression. They were randomized to Brief-PsT (n = 141) or Short-PsT with a more extended focus (n = 143). Primary outcome was the transition of WP-state from baseline to 3 months follow-up. In addition, WP at 12 and 24 months follow-up were assessed. The secondary outcome, clinical recovery rate (CR-rate) was obtained from the Beck Depression and Beck Anxiety Inventories, at 2-year follow-up. In addition, self-reported mental health symptom severity, self-efficacy, subjective health complaints and life satisfaction were assessed. Results At 3 months follow-up, the increase in WP was significantly greater in Brief-PsT than in Short-PsT (p = 0.039). At 3 months, 60% in Brief-PsT and 51% in Short-PsT was at work, partial or full. Thereafter, these differences diminished, 84% and 80% were at work at 2-year follow up. The 2-year follow-up of the secondary outcome measurements was completed by 53% in Brief-PsT and 57% in Short PsT. CR-rate was significantly greater in Brief-PsT compared with the Short-PsT (69% vs. 51%, p = 0.024). Furthermore, there was a greater reduction in the number of subjective health complaints in Brief-PsT (4.0 vs. 1.9 p = 0.012). All other measurements favoured Brief-PsT as well, but did not reach statistical significance. Conclusions Brief coping-focused psychotherapy added to group education for persons with depression or anxiety complaints seemed more effective in enhancing early work participation compared with additional short-term psychotherapy of standard duration with more extended focus. Clinical recovery rate and decline of comorbid subjective health complaints at 2-year follow-up were also in favour of the brief coping-focused program.

  Objective: Thorough description of objectively assessed physical activity (PA) and sedentary time in people with schizophrenia is lacking, and previous studies comparing PA and cardiorespiratory fitness levels with healthy controls are limited by their small sample size and/or poor methodology. Method: PA, sedentary behavior, and cardiorespiratory fitness level were assessed in 67 adults diagnosed with schizophrenia (EPHAPS study) and compared with a population-based sample of 2809 adults (NPASS study). Results: Fifty-five percent of the participants with schizophrenia had the unhealthy combination of not meeting the PA recommendations and sitting >7.5 h per day compared to 32% in the population-based sample. The PA level was especially low on weekday afternoons and evenings and throughout most of the day on weekends. The peak oxygen uptake for EPHAPS women was on average 23% lower than that for NPASS women, while EPHAPS men achieved on average 34% lower oxygen uptake on the exercise test compared with NPASS men. Conclusion: People with schizophrenia are significantly less physically active, more sedentary, and have a poorer cardiorespiratory fitness level compared with the general population. Tailor-made PA interventions for people with schizophrenia should target their PA and sedentary behavior on afternoons and weekends especially.

  Objective: Schizophrenia is associated with reduced cardio-respiratory fitness (CRF), and impaired cognition is a core feature of the disorder. Despite their particular significance to schizophrenia disparately, the relationship between these two variables has not yet been thoroughly assessed. In this study we aimed to investigate naturally occurring associations between CRF and all cognitive domains within this patient population. Method: Eighty outpatients with schizophrenia spectrum disorders participated in the study. Neurocognition was assessed with the Wechsler Adult Intelligence Scale version 4 General Ability Index (WAIS GAI) and the MATRICS Consensus Cognitive Battery (MCCB). Oxygen uptake was measured directly by analyzing O2 and CO2 content in expired air during a maximum exercise session on a treadmill using a modified Balke protocol. Clinical symptom load was assessed with the Positive and Negative Syndrome Scale (PANSS). Hierarchical multiple regression analyses were conducted, controlling for sex and age, and negative psychotic symptom levels. Results: CRF explained a significant 8.2% and 9.1% of the variance in general intellectual ability and state-sensitive cognitive functioning respectively, beyond the impact of negative psychotic symptom load. Conclusion: The study indicates a direct relation between CRF and cognition in schizophrenia. Impaired cognition is a difficult-to-treat expression of the disorder, and identifying modifiable factors possibly mediating cognition, such as CRF, is of great clinical value.

  Abstract Objective We investigated whether the relationship between cardio-respiratory fitness (CRF) and cognition in schizophrenia is general, or due to selective relationships between CRF and specific aspects of cognitive function. Method Eighty outpatients with schizophrenia spectrum disorders participated. Neurocognition was assessed with the Wechsler Adult Intelligence Scale version 4 General Ability Index (WAIS GAI), the MATRICS Consensus Cognitive Battery (MCCB) and the Emotion in Biological Motion (EBM) test. CRF was assessed with peak oxygen uptake measured directly during maximum exercise using a modified Balke protocol. Partial correlations, controlling for sex and age, were obtained for the perceptual and the verbal indices of WAIS GAI, six cognitive domains of MCCB, and the EBM total score. A factor analysis was conducted on all 15 subtests of the WAIS GAI and the MCCB, and the factors were subjected to separate regression analyses with CRF as predictor. Results Significant, moderately sized correlations were found between CRF and all cognitive domains except processing speed. The correlation appeared strongest for CRF and the Verbal Comprehension Index of WAIS GAI (r = 0.29, p = .005). The factor analysis identified three factors: one speed/attention/executive function factor, one verbal factor, and one perceptual factor. Regression analyses showed that VO2peak explained a significant amount of variance in the verbal factor only (R2 = 0.06, β = 0.329, p = .03). Conclusion The results indicate that the relationship between CRF and cognition in schizophrenia is selectively tied to a modality-specific association with verbal cognitive abilities. These findings have implications for understanding the relation between cognitive factors and physical health in schizophrenia.

  Objective: The aim is to investigate the everyday executive function (EF) in children with Tourette syndrome (TS), Inattentive or Combined presentations of ADHD (ADHD-I/ADHD-C), autism spectrum disorders (ASD), and typically developing children (TDC). Method: Nineteen TS, 33 ADHD-C, 43 ADHD-I, 34 ASD, and 50 TDC participated (8-17 years). Parents completed the Behavior Rating Inventory of Executive Function (BRIEF). Results: TS, ADHD-C, ADHD-I, or ASD were rated with significantly more regulation problems on all scales compared with TDC. Considerable overlap of symptoms between clinical groups made differentiation difficult on individual scales. Scale configurations showed children with TS to have more problems with emotional control (EC) than cognitive flexibility in relation to children with ASD, more problems with EC than inhibitory control in relation to ADHD-C, and more problems with EC than planning/organizing in relation to ADHD-I. Conclusion: Paired BRIEF scales dissociated EF problems in children with TS from children with ADHD-C, ADHD-I, or ASD. Clinical relevance is discussed.

  The preschool period is an important developmental period for the emergence of cognitive self-regulatory skills or executive functions (EF). To date, evidence regarding the structure of EF in preschool children has supported both unitary and multicomponentmodels. The aimof the present study was to test the factor structure of early EF as measured by the Behavior Rating Inventory of Executive Function-Preschool version (BRIEF-P). BRIEF-P consists of five subscales and three broader indexes, hypothesized to tap into different subcomponents of EF. Parent ratings of EF from a nonreferred sample of children recruited from the Norwegian Mother and Child Cohort Study (N = 1134; age range 37–47 months) were subjected to confirmatory factor analyses (CFA). Three theoretically derived models were assessed; the secondorder three-factor model originally proposed by the BRIEF-P authors, a “true” first-order one-factor model and a second-order one-factor model. CFA fit statistics supported the original three-factor solution. However, the difference in fit was marginal between this model and the second-order one-factor model. A follow-up exploratory factor analysis (EFA) supported the existence of several factors underlying EF in early preschool years, with a considerable overlap with the five BRIEF-P subscales. Our results suggest that some differentiation in EF has taken place at age 3 years, which is reflected in behavior ratings. The internal consistency of the BRIEF-P five clinical subscales is supported. Subscale interrelations may, however, differ at this age from those observed in the preschool group as a whole.

  The aim of this study was to analyse the development of verbal working memory in children with high-functioning autism compared to children with attention-deficit/hyperactivity disorder and typically developing children. A total of 34 children with high-functioning autism, 72 children with attention-deficit/hyperactivity disorder and 45 typically developing children (age 9–16 years) were included at baseline and followed up approximately 25 months later. The children were given a letter/number sequencing task to assess verbal working memory. The performance of children with high-functioning autism on verbal working memory did not improve after 2 years, while improvement was observed in children with attention-deficit/hyperactivity disorder and typically developing children. The results indicate a different developmental trajectory for verbal working memory in children with high-functioning autism compared to children with attention-deficit/hyperactivity disorder and typically developing children. More research is needed to construct a developmental framework more suitable for children with autism spectrum disorder.

  This study explored differences in the factor structure of depressive symptoms in patients with and without alcohol abuse, and differences in the severity of depressive symptoms between the two groups. In a sample of 358 patients without alcohol problems and 167 patients with comorbid alcohol problems, confirmatory factor analysis revealed that the same factor structures, Beck et al.’s two-factor Somatic Affective-Cognitive (SA-C) model, and Buckley et al.’s three-factor Cognitive-Affective- Somatic (C-A-S) model, demonstrated the best fit to the data in both groups. The SA-C model was preferred due to its more parsimonious nature. Evidence for strict measurement invariance across the two groups for the SA-C model was found. MIMIC (multiple-indicator-multiple-cause) modeling showed that the level of depressive symptoms was found to be highest on both factors in the group with comorbid alcohol problems. The magnitude of the differences in latent mean scores suggested a moderate difference in the level of depressive symptoms between the two groups. It is argued that patients with comorbid depression and alcohol abuse should be offered parallel and adequate treatment for both conditions.

  Subjects with ADHD are often impaired in visuo-motor tasks. However, little is known about the contribution of modal impairment in motor function relative to central processing deficits or whether different processes underlie the impairment in ADHD combined (ADHD-C) versus ADHD inattentive (ADHD-I) subtype. The present study analyzes performance on the Visual Motor Integration test relative to less effortful motor tests as well as on measures of Energetics. Results: Both ADHD groups showed evidence of impaired motor function on both VMI and the less effortful motor tests. The ADHD-C group performed below the ADHD-I group on VMI, but their performance correlated highly with the measures of the Energetic pools of Arousal and Effort. Conclusion: Different mechanisms may underlie impaired fine motor skills in ADHD. Central processing deficits contribute significantly to the deficit of ADHD-C but do not explain the motor impairment in ADHD-I.

  Reply by the current author to the comments made by A. Vaskinn (see record 2019-31702-001) on the original article (see record 2019-06987-001). My colleague Vaskinn published recently a commentary on my study on Emotion Perception in Norwegian Mensa. My study is the first to actually test social cognition in Mensa Members, although self-ratings have been published previously. Vaskinn questions the validity of the finding that Mensa members score superior to community controls on the EmoBio test of emotion recognition. Her point is important, and that is why all research has to be replicated with new community samples as well as new experimental groups. There are, however, two possible reasons for the difference in scores. The first is related to the distribution of age in her study compared to the Mensa study. The community sample in the Mensa study was graduate students from a local high school and employees in a national governmental agency. There were no exclusion criteria. They were tested in a group session, everyone was given a scoring sheet and a pen. The testing was incorporated in a guest lecture on psychology in the High School and on social abilities in the governmental agency.

  Studies have shown that children with ADHD profit from Working Memory training, although few studies have investigated transfer effects comprehensively. The present study analyzes transfer both to other neuropsychological domains, academic performance and daily life functioning at home and school. Seventy-two children with ADHD were randomized into a control group or a training group completing Cogmed’s RoboMemo program. They were assessed pre-training, immediately after and eight months later with a battery of neuropsychological tests, measures of mathematical and reading skills as well as rating scales filled out by parents and teachers. There were significant training effects in psychomotor speed, and to one of several measures of controlled attention but no effect on memory. Reading and mathematics were improved. Inattention-ratings at home were differentially reduced in the training group, but more detailed mapping of executive function by BRIEF, did not show improvement. There was no improvement in teacher ratings. Generally, improvements attained immediately post training also remained eight months later. The study is the most comprehensive study of transfer effects to date, and with mixed results compared to previous research. More research is needed as to how improve the training program and regarding conditions and thresholds for successful training.
