No evidence of a minimal clinically important difference for the Beery-Buktenica Developmental Test of Visual-Motor Integration in children with autism spectrum disorder

The Beery Visual-Motor Integration (VMI) battery of tests are some of the most commonly used assessments in pediatric occupational therapy, often used to measure change over time. However, the minimal clinically important difference (MCID) has not been estimated for interpreting change scores. We estimated the MCID for the Beery VMI battery of tests in children with autism spectrum disorder (ASD). Four occupational therapists collected data in a public elementary school on 64 children with ASD. The Beery VMI battery was administered to children with ASD twice, approximately 11 months apart. To estimate MCID values, Beery VMI battery scores were anchored to 15-point Likert questions measuring occupational therapists’ ratings of functional change over three domains: fine motor skills, handwriting, and activities of daily living (ADLs). Using this anchor-based method, we were unable to estimate MCID values for the Beery VMI battery. Children’s Beery VMI battery scores did not change significantly over the course of the school year, and there was only one weak correlation between VMI battery change scores and therapists’ ratings of change. The inability to estimate Beery VMI battery MCID values for children with ASD adds further support for research cautioning the use of the Beery VMI as an outcome measure.

Placebo Responses and Their Clinical Implications in Fibromyalgia: A Meta-Analysis Using SSRI and SNRI Trials

Background: Fibromyalgia (FM) is a chronic primary pain condition, associated with widespread musculoskeletal pain, disturbed sleep, fatigue, cognitive dysfunction, and a range of comorbid conditions such as irritable bowel syndrome, and depression. Despite its high prevalence of 2% in the general population, FM continues to pose scientific and clinical challenges in definition, etiology, and day-to-day management. In terms of treatment, FM can be treated with selective serotonin reuptake inhibitors (SSRIs), serotonin-norepinephrine reuptake inhibitors (SNRIs).Objective: Patients with FM and other chronic primary pain syndromes are known to experience substantial and clinically relevant placebo effects. An update of the placebo responses for various outcomes in the FM population and especially a discussion about clinical implications is therefore needed.Methods: We used data from a large data pool that includes randomized controlled trials (RCTs) examining within-placebo mean change scores of baseline vs. follow-up assessments in FM trials of SSRIs and SNRIs. The primary outcomes were pain, functional disability, and depression and using different scales. We assessed heterogeneity of included trials.Results: A total of 29 RCTs with N = 8,453 patients suffering from FM were included in our analysis. Within-placebo mean change scores of baseline vs. follow-up assessments were large for pain (mean change = 2.31, 95% CI: 0.42–4.21, p = 0.017), functional disability (mean change = 3.31, 95% CI: 2.37–4.26, p < 0.000), and depression (mean change = 1.55, 95% CI: 0.92–2.18, p < 0.000). Heterogeneity was found to be large for all outcomes.Impact: Our results provide preliminary evidence that placebo responses, which also consist of non-specific effects, might play a role in the treatment of FM. Furthermore, we highlight limitations of our analyses and make suggestions for future studies.

Interrelations between enhanced emotional intelligence, leadership self-efficacy and task-oriented leadership behaviour–a leadership coaching study

PurposeThe purpose of this paper is to investigate interrelations between enhanced emotional intelligence, leadership self-efficacy and task-oriented leadership behaviour following participation in leadership coaching.Design/methodology/approachOrganisational leaders (coachees) (N = 70) and their subordinates (N = 175) completed online questionnaires pre- and post-coaching. To account for pre-coaching scores, construct latent change scores were assessed using partial least squares structural equation modelling (PLS-SEM).FindingsResults indicate a positive association between enhanced emotional intelligence and leadership self-efficacy, however, little support was found for leadership self-efficacy as a mediator explaining an association between enhanced emotional intelligence and task-oriented leadership behaviour.Practical implicationsOrganisations aiming to improve leader performance through enhancing emotional intelligence and leadership self-efficacy may find value in leadership coaching due to the intervention's positive effect on these constructs, and the positive association observed between developmental changes in these constructs.Originality/valueResearch on the interrelation between emotional intelligence and leadership self-efficacy is scarce. This study extends the literature by investigating the interrelation between developmental changes between these constructs brought about by leadership coaching using latent change scores and PLS-SEM. The study also assesses whether enhanced leadership self-efficacy mediates an association between enhanced emotional intelligence and task-oriented leadership behaviour building on the literature explaining coaching's effect mechanisms.

NCOG-48. LONGITUDINAL ASSESSMENT OF SUBJECTIVE COGNITIVE FUNCTION IN A BRAIN TUMOR SAMPLE: IMPROVED CORRESPONDENCE WITH NEUROPSYCHOLOGICAL PERFORMANCE OVER TIME

INTRODUCTION Estimates of subjective cognitive function (SCF) generally show minimal correlation with objective measures of neurocognitive function (NCF). Our group recently validated a new metric of SCF in neuro-oncology patients, creating the Cognitive Index of the Functional Assessment of Cancer Therapy-Brain (FACT-Br-CI). This study examines whether brain tumor (BT) patients evaluated on more than one occasion show improved relationship between SCF and NCF. We hypothesized that change scores in SCF and NCF across evaluation would be more highly correlated than SCF and NCF at either timepoint. METHODS A retrospective study of BT patients who completed two neuropsychological evaluations (baseline, follow-up) was conducted. NCF was measured by the clinical trial battery composite (CTBC), a mean of 6 commonly used neuropsychological test scores. SCF was measured by the FACT-Br-CI. Mood/Anxiety were measured by the Beck scales (BAI/BDI-II). Change over time on each metric was evaluated with paired t-test. Correlational analyses evaluated relationships between NCF, SCF, and mood within and between time points. RESULTS Twenty-nine patients (16 female; mean age=54.6y; mean education=15.5y) completed all CTBC measures and FACT-Br-CI, 28 of whom completed and BDI and/or BAI. On group analyses, there were no significant differences between baseline and follow-up on CTBC (t=-.53;p=ns) or FACT-Br-CI (t=-.98;p=ns). Correlations between CTBC and FACT-Br-CI were nonsignificant at baseline (r=.24;p=ns), but significant at follow-up (r=.56;p=0.002). Change scores over time were unrelated (r=-.104;p=ns). Similar to previous studies, the FACT-BR-CI correlated with the BDI-II at baseline (r=-.38;p=0.04) and follow-up (r=-.59;p< 0.001) and with the BAI at follow-up (r=-.44;p=0.02). CONCLUSION In this small group of brain tumor patients seen for repeated neuropsychological evaluations, we found that agreement between SCF and NCF was much higher on their second than initial evaluation. These findings suggest that patients may develop enhanced awareness of their cognitive function from an initial evaluation that persists over time.

NCOG-43. RELATIONSHIPS BETWEEN MOOD DISTURBANCE, SYMPTOM INTERFERENCE, AND DISEASE PROGRESSION IN GLIOMA PATIENTS

Cross-sectional studies indicate that patients with gliomas report significant depressive/anxiety symptoms and symptom-related interference with daily activities at diagnosis and throughout the illness trajectory. Our study aimed to explore relationships between these mood disturbances and symptom interference with respect to progressive disease (PD) in glioma patients. Demographic, clinical characteristics, MDASI-Brain Tumor (interference items), and PROMIS Anxiety and Depression Short-Forms were collected at the time of imaging surveillance, before discussing imaging results. Comparisons between patients with/without PD and respective change scores were calculated at study entry and at subsequent assessments. Independent t-tests, Chi-square tests, and paired sample t-tests were used to report results. The sample included 438 glioma patients (62% male, 84% Caucasian, 82% high-grade) with median age of 51 years (range 18-82); 42% had PD with 60% reporting past recurrence(s); 45% had poor Karnofsky Performance Status (KPS); and median time from diagnosis was 2 years (range: 0-30). On average, patients with PD on imaging at time of assessment reported significantly greater anxiety (p = 0.008), depression (p < 0.001), and symptom interference (p < 0.001) than those with stable disease. Additionally, more patients with PD reported moderate-severe anxiety (25%) and depression (22%) than patients with stable disease (15% and 12%, respectively). When evaluating change scores, patients with PD reported worse symptom interference (p < 0.001) but stable mood disturbance, while patients with stable disease reported improved depression (p = 0.018) and unchanged anxiety symptoms compared to baseline. Although mood disturbance is higher for patients with PD, some of these patients do not experience worsening, but rather a continuation of ongoing psychological symptoms, which may portend a worse illness trajectory. Identifying these patients early in this trajectory to evaluate potential biologic correlates between mood and prognosis is warranted to validate these findings.

NCOG-20. LONGITUDINAL ASSESSMENT OF SUBJECTIVE COGNITIVE FUNCTION IN ADULTS WITH LOW GRADE GLIOMA TREATED WITH PROTON RADIATION THERAPY

INTRODUCTION Our group previously demonstrated stability in neurocognitive function (NCF) over a 5-year period after proton radiation therapy (PRT) in low grade glioma (LGG) patients. Subjective cognitive function (SCF) had not been previously explored, nor had individual analyses of cognition, which can detect variability in trajectory. We used the newly derived Functional Assessment of Cancer Therapy-Brain Cognitive-Index (FACT-Br-CI) to examine SCF in LGG patients after PRT and compare longitudinal changes in SCF and NCF. METHODS 20 LGG patients (M age =37.5) treated with PRT completed NCF tests and self-report measures annually for 5 years or until tumor progression. Group change in SCF was examined with paired t-test (baseline vs final FACT-Br-CI). Individual change scores were calculated for FACT-Br-CI and NCF tests (clinical trials battery composite; CTBC). Individual deterioration in NCF was defined by reliable change index (RCI) on CTBC, and in SCF was defined as decline of >/=1 SD in FACT-Br-CI. Relationships between change in SCF and NCF were explored with correlations. RESULTS At the group level, no change was observed in FACT-Br-CI between baseline and last follow-up (t(19)=-.91;p=ns). Individual SCF analyses at last follow-up found the number of patients reporting decline=3 (15%), improvement=5 (25%), and no change=12 (60%). Individual changes were observed in SCF in 20% of patients at 3 months, 5.9% at 6 months, 12.5% at 12 months, 13.3% at 24 months, and 11.1% at 36 months. Median time to any deterioration in SCF was 36 months and for NCF was not reached. Correlation between CTBC and FACT-Br-CI change scores did not reach statistical significance (r=.41;p=ns). CONCLUSION Consistent with previous research, group analyses of LGG patients did not show cognitive decline after PRT. However individual analyses of SCF showed variability within the group: some patients experienced cognitive decline during follow up. Consideration of individual differences may yield additional information.

Detecting change in community participation with the Enfranchisement scale of the community participation indicators

Objective This study determined the sensitivity to change of the Enfranchisement scale of the Community Participation Indicators in people with stroke. Data sources We analyzed data from two studies of participants with stroke: an intervention study and an observational study. Main measures The Enfranchisement Scale contains two subscales: the Importance subscale (feeling valued by and contributing to the community; range: 14–70) and the Control subscale (choice and control: range: 13–64). Data analysis Assessments were administered 6 months apart. We calculated minimum detectable change and minimal clinically important difference. Results The Control subscale analysis included 121 participants with a mean age of 61.2 and mild-moderate disability (Functional Independence Measure, mean = 97.9, SD = 24.7). On the Control subscale, participants had a mean baseline score of 51.4 (SD = 10.4), and little mean change (1.3) but with large variation in change scores (SD = 11.5). We found a minimum detectable change of 9 and a minimum clinically important difference of 6. The Importance subscale analysis included 116 participants with a mean age of 60.7 and mild-moderate disability (Functional Independence Measure, mean = 98.9, SD = 24.5). On the Importance subscale, participants had a mean baseline score of 44.1 (SD = 12.7), and again demonstrated little mean change (1.08) but with large variation in change scores (SD = 12.6). We found a minimum detectable change of 11 and a minimum clinically important difference 7. Conclusions The Control subscale required 9 points of change, and the Importance subscale required 11 points of change, to achieve statistically and clinically meaningful changes, suggesting adequate sensitivity to change.

The Impact of Neurocognitive Functioning on the Course of Posttraumatic Stress Symptoms following Civilian Traumatic Brain Injury

Background: One out of seven individuals who have suffered a traumatic brain injury (TBI) develops a posttraumatic stress disorder (PTSD), which is often associated with neurocognitive impairment. The present study explores the impact of neurocognitive functioning after mild, moderate, and severe TBI on the course of PTSD symptoms. Methods: The data of 671 adults admitted to hospital for a TBI was drawn from the Collaborative European Neurotrauma Effectiveness Research (CENTER-TBI) study. After six- and 12-months post-injury, participants completed the PTSD Checklist-5 (PCL-5), from which change scores were calculated. At six months, participants also completed a neurocognitive assessment including the Rey Auditory Verbal Learning Test, the Trail Making Test, and the Cambridge Neuropsychological Test Automated Battery (CANTAB). Linear regressions were performed to identify associations between cognitive functioning and PCL-5 change scores. Results: Overall, mean PCL-5 change scores showed no clear change (−0.20 ± 9.88), but 87 improved and 80 deteriorated by a change score of 10 or more. CANTAB Rapid Visual Information Processing scores were significantly associated with PCL-5 change scores. Conclusions: Strong sustained attention was associated with improvement in PTSD symptoms. Assessing cognitive performance may help identify individuals at risk of developing (persisting) PTSD post-TBI and offer opportunities for informing treatment strategies.

The importance of formal versus informal mindfulness practice for enhancing psychological wellbeing and study engagement in a medical student cohort with a 5-week mindfulness-based lifestyle program

Purpose Medical students commonly experience elevated psychological stress and poor mental health. To improve psychological wellbeing, a 5-week mindfulness-based lifestyle course was delivered to a first-year undergraduate medical student cohort as part of the core curriculum. This study investigated the effects of the program on mental health, perceived stress, study engagement, dispositional mindfulness, and whether any improvements were related to amount of formal and/or informal mindfulness practice. Methods Participants were first year undergraduate medical students (N = 310, 60% female, M = 18.60 years) with N = 205 individuals completing pre and post course questionnaires in a 5-week mindfulness-based lifestyle intervention. At pre- and post-intervention, participants completed the Mental Health Continuum-Short Form, the Perceived Stress Scale, the Utrecht Work Engagement Scale for Students, the Freiburg Mindfulness Inventory, and the Mindfulness Adherence Questionnaire. Results Mental health, perceived stress, study engagement, and mindfulness all improved from pre- to post-intervention (all p values < .001). Improvements on these outcome measures were inter-related such that PSS change scores were negatively correlated with all other change scores, FMI change scores were positively correlated with MHC-SF and UWES-S change scores, the latter of which was positively correlated with MHC-SF change scores (all p values < .01). Finally, observed improvements in all of these outcomes were positively related to informal practice quality while improved FMI scores were related to formal practice (all p values < .05). Conclusions A 5-week mindfulness-based program correlates with improving psychological wellbeing and study engagement in medical students. These improvements particularly occur when students engage in informal mindfulness practice compared to formal practice.

Mindfulness training during brief periods of hospitalization in multiple sclerosis (MS): beneficial alterations in fatigue and the mediating role of depression

Objectives Persons with MS (PwMS) are frequently affected by fatigue and depression. Mindfulness-based interventions may reduce these symptoms in PwMS and consequently their application has been extended to various settings. Only few efforts have been made to explore effects of short-term mindfulness training during brief periods of hospitalization. In the current study, the feasibility and potential effects of short-term mindfulness training on depression, fatigue, rumination and cognition were explored in PwMS in an acute-care hospital setting. Based on previous work, it was further examined whether the relation between trait mindfulness and fatigue prior to and following the intervention was mediated by depression and whether a mediation effect was also observable throughout the intervention. Methods A short-term mindfulness training protocol was developed, tailored to the requirements of the acute-care setting. Subsequently, 30 PwMS were recruited sequentially and received mindfulness training during the routine clinical process (median duration in hospital: eight days, number of sessions: four). Participants completed relevant self-report measures (depression, fatigue, rumination) and a neuropsychological assessment before and after training. Results Participants reported significantly increased trait mindfulness and decreased depression and fatigue following the intervention. Respective change scores were highly correlated so that increased trait mindfulness was associated with decreased symptoms. In the rumination domain, patients reported a tendency for an increased adaptive ability to engage in distractive behavior during arising negative mood. Other measures of trait rumination and cognition remained relatively stable. Results of the mediation analyses indicated that depression mediated the negative relationship between trait mindfulness and fatigue symptoms at pre and post assessments. With regards to the change scores, an association between mindfulness and cognitive fatigue ceased to be significant when depression was controlled, albeit in this case, the mediation effect did not reach significance. Conclusion Results of the current study indicate that short-term mindfulness training during brief periods of hospitalization may be beneficial for PwMS. They further complement previous work by identifying depression as a potential mediator of the antagonistic relationship between mindfulness and fatigue. Based on the current exploratory study, future trials are warranted to address this mechanism of mindfulness training in more detail.
