A pilot study evaluating online training for therapist delivery of interpersonal psychotherapy for eating disorders.

OBJECTIVE: Individuals with eating disorders (EDs) often do not receive evidence-based care, such as interpersonal psychotherapy (IPT), partly due to lack of accessible training in these treatments. The standard method of training (i.e., in-person workshops) is expensive and time consuming, prompting a need for more scalable training tools. The primary aim of this pilot and open trial was to examine the effects of an IPT online training platform on training outcomes (i.e., IPT fidelity, knowledge, and acceptance) and, secondarily, whether online training was different from in-person training (using a comparative sample from a separate study) in terms of training outcomes and patient symptoms. METHOD: Participants were therapists (N = 60) and student patients (N = 42) at 38 college counseling centers. Therapists completed baseline questionnaires and collected data from a student patient with ED symptoms. Therapists then participated in an IPT online training program and completed post-training assessments. RESULTS: Following online training, acceptance of evidence-based treatments, therapist knowledge of IPT, therapist acceptance of IPT, and treatment fidelity increased; acceptance of online training was high at baseline and remained stable after training. Using the 90% confidence interval on outcome effect sizes, results suggested IPT online training was not different from in-person training on most outcomes. Results are based on 60% of therapists who originally enrolled due to high dropout rate of therapist participants. CONCLUSIONS: Findings from this preliminary pilot study support the use of IPT online training, which could increase access to evidence-based ED treatment and improve patient care. PUBLIC SIGNIFICANCE: Lack of accessible therapist training has contributed to many therapists not delivering, and therefore many patients not receiving, evidence-based treatment. This study evaluated a highly disseminable online training and compared outcomes to traditional in-person training and found that training and patient outcomes were not different. Online training has the potential to enhance access to evidence-base care, which could in turn optimize patient outcomes.

Exploring the interagency collaboration between a pediatric oncology health care setting and community schools.

Globally, approximately 400,000 youth are diagnosed with pediatric cancer each year. Treatment-related side effects, psychosocial challenges, and frequent school absences may adversely impact learning and the education experience among these youth. Efforts to enhance interagency collaboration between health care settings and community schools are imperative to facilitate school reintegration. The Standards for the Psychosocial Care of Children with Cancer and Their Families outline specific guidelines related to the continuity of education for students impacted by pediatric cancer. In particular, the Academic Continuity and School Reentry Support and Monitoring and Assessment of Neuropsychological Outcomes standards of care highlighted within this article align with extant programmatic efforts for transitioning hospitalized school-aged children back into community schools. This article aims to describe systematic programmatic efforts within hospital-based psychosocial programs that are consistent with the Standards for the Psychosocial Care of Children with Cancer and Their Families, as well as interagency collaboration with community schools to support student-centered education for youth impacted by pediatric cancer. Resources for school psychologists, teachers, hospital-based programs, and others involved in student-centered education for pediatric cancer patients and survivors are presented.

Understanding the Role of CalFresh Participation and Food Insecurity on Academic Outcomes among College Students during the COVID-19 Pandemic.

Food insecurity (FI) is associated with many adverse outcomes in college students. The Supplemental Nutrition Assistance Program (SNAP, known as CalFresh in California) has been observed to alleviate FI; however, on college campuses, the benefits of food assistance programs are not well understood. This study investigated whether college students benefit from CalFresh participation. It was hypothesized that students would experience increased FI over time and that CalFresh participation would moderate the effect of FI on grade point average (GPA). A comprehensive FI and CalFresh questionnaires were distributed during the 2020-2021 academic year to 849 students. The chi-square test of independence assessed differences between FI and student factors. A Friedman test assessed differences in FI during the three quarters. Moderation analysis assessed whether CalFresh participation moderated FI's effect on GPA. Differences were observed among food security scores in Winter 2021 (median = 1.69) and Fall 2020 (median = 2.14; p = 0.013) and Spring 2020 (median = 2.17; p = 0.009). In the moderation model, the interaction of FI score and CalFresh participation was positively correlated with GPA (B = 0.11; p = 0.002). These results indicate that SNAP/CalFresh participation was particularly beneficial for mitigating the negative effects of FI on GPA. Given these benefits, encouraging SNAP/CalFresh enrollment should be a priority for university administrators.

The toll of transition: Caregiver perceptions of family adjustment during the transition off pediatric cancer therapy.

OBJECTIVE: The role of transition-focused psychology appointments in managing the transition off therapy is unclear. The objective of this research was to explore caregiver perceived familial distress and the role of psychology in preparing families for transition. METHODS: Fifty-seven caregivers of youth, who finished treatment, completed an online questionnaire through a quality improvement project on experiences of families at transition. Twenty-two percent of caregivers had children who completed a transition-focused psychology consult and 63% completed a cognitive assessment at transition. Retrospective analyses were conducted assessing the association of psychology visits on caregiver perceptions of being informed of and prepared to manage transition-related challenges. RESULTS: Most caregivers reported experiencing adjustment concerns for family members. Caregivers of children completing a transition-focused psychology consult or cognitive assessment reported feeling more informed and greater preparedness to manage difficulties. Although decreased distress was not associated with the visit, those who felt more informed and prepared reported lower distress. CONCLUSIONS: Caregivers perceive transitioning off therapy as stressful for their family, though they experience decreased familial distress when informed of and prepared to manage transition-related challenges. These findings highlight the importance of psychosocial support at transition.

Evaluating Knowledge, Attitudes, and Practices Regarding CalFresh Participation in University Students.

Objective: (1) Identify demographic and academic differences among university students who are food secure or food insecure and (2) explore CalFresh knowledge, attitudes, and practices (KAPs) among university students. Design: A questionnaire, including the 10-item USDA Adult Food Security Survey Module, CalFresh KAPs, and student factors was distributed in Winter 2020 to 10,000 university students. Chi-square test of independence, logistic and linear regressions were used to assess associations between food-secure status and student factors. Exploratory factor analysis determined factors relating to CalFresh KAPs. Kendall's tau assessed association between CalFresh KAPs factors. Setting: A public research university in California. Participants: Enrolled undergraduate and graduate/professional students (n = 10,000). 1535 responses with 1408 included in analysis for having complete data. Results: Food insecurity was associated with: race/ethnicity (Latino/a, OR = 1.97; p < 0.001); first-generation status (OR = 2.01; p < 0.001); and transfer status (OR = 1.58; p = 0.01). Exploratory factor analysis identified five factors related to CalFresh knowledge and attitudes: (1) CalFresh knowledge, (2) Positive attitudes around participating in CalFresh, (3) Negative attitudes around participating in CalFresh, (4) Negative attitudes around others participating in CalFresh, and (5) Fortunate attitudes for not participating in CalFresh. CalFresh knowledge was correlated with positive attitudes towards CalFresh participation (τb = 0.15, p = 0.025); negative attitudes towards other individuals' CalFresh participation (τb = −0.28, p < 0.001); feeling fortunate for not needing CalFresh (τb = 0.12, p = 0.004); and CalFresh participation OR = 1.40; p = 0.02). Conclusions: CalFresh knowledge may influence program participation. Populations who are most impacted by food insecurity should be a focus for improving CalFresh knowledge to promote CalFresh participation.

Measuring Skin Carotenoids Using Reflection Spectroscopy in a Low-Income School Setting.

Dietary behavior change is difficult to accurately measure in a low-income youth population. Objective tools to measure fruit and vegetable consumption without relying on self-report present the opportunity to do this with less respondent burden and bias. A promising tool for quantifying fruit and vegetable consumption via proxy is skin carotenoids as measured by reflection spectroscopy through a device called the Veggie Meter®. To assess whether the Veggie Meter® is able to detect changes in skin carotenoids as a proxy for fruit and vegetable consumption in a low-income school setting, skin carotenoid measurements were collected at three time points, along with student level demographics, anthropometric measurements, and nutrition knowledge. A secondary goal of this study was to refine the protocol to be used based on researcher observations. Repeated measures analysis of variance with Bonferroni correction for multiple comparisons indicate that there was a significant difference in VM scores over the course of the study (F(2, 68) = 6.63, p = 0.002), with an increase in skin carotenoids from Fall 2018 to Spring 2019 (p = 0.005). This increase was sustained over the summer months when measured in Fall 2019. Changes to the protocol included the addition of a hand cleaning step and using the non-dominant ring finger for data collection. With these refinements, the results demonstrate that the Veggie Meter® is usable as a non-invasive tool for measuring fruit and vegetable consumption in a population that is traditionally difficult to assess.

Validity and Reliability of a Nutrition Knowledge Questionnaire for High School-Aged Adolescents.

OBJECTIVE: To determine the validity and reliability of a nutrition knowledge questionnaire for adolescents. METHODS: An adult questionnaire was administered to 4 high school student convenience samples with and without known prior nutrition education. Questionnaire refinement was determined by item-total correlation, item discrimination, and item difficulty. Mean percentage of correct answers was calculated, and the group difference was assessed using an independent samples t test. A post hoc regression analyzed the association between mean percentage of correct answers and group while controlling for school. RESULTS: The questionnaire, with 1 question eliminated, had good internal consistency reliability (Cronbach α = 0.83). The nutrition education group (n = 174) demonstrated significantly (P < 0.0001) higher mean percentage of correct answers compared with the no nutrition education group (n = 136). The association between mean percentage of correct answers and the group remained with school controlled. CONCLUSIONS AND IMPLICATIONS: Results suggest that the questionnaire is valid and reliable for measuring nutrition knowledge in high school-aged adolescents.

The Influence of Environmental Consequences and Internalizing Symptoms on Children's Tic Severity.

Although there is evidence that environmental consequences for displaying tics and internalizing symptoms are related to tic severity in children with TS, less is known about the inter-relationships of these variables or how these factors jointly contribute to tic severity. This study included 45 children with Tourette syndrome. Caregivers reported on children's environmental consequences for displaying tics, internalizing symptoms, and tic severity. Results indicated that children with higher levels of internalizing symptoms experienced significantly more environmental consequences for displaying tics. Children with higher levels of separation anxiety symptoms demonstrated significantly greater tic severity. Environmental consequences for displaying tics accounted for significantly more variance in predicting tic severity than anxiety symptoms. This preliminary evidence suggests that environmental consequences for displaying tics, such as receiving accommodations or attention from others, have a greater influence on children's tic severity than emotional factors.

Reduction in Thrombosis and Bacterial Adhesion with 7 Day Implantation of S-Nitroso-N-acetylpenicillamine (SNAP)-Doped Elast-eon E2As Catheters in Sheep.

Thrombosis and infection are two common problems associated with blood-contacting medical devices such as catheters. Nitric oxide (NO) is known to be a potent antimicrobial agent as well as an inhibitor of platelet activation and adhesion. Healthy endothelial cells that line the inner walls of all blood vessels exhibit a NO flux of 0.5~4×10-10 mol cm-2 min-1 that helps prevent thrombosis. Materials with a NO flux that is equivalent to this level are expected to exhibit similar anti-thrombotic properties. In this study, NO-releasing catheters were fabricated by incorporating S-nitroso-N-acetylpenicillamine (SNAP) in the Elast-eon E2As polymer. The SNAP/E2As catheters release physiological levels of NO for up to 20 d, as measured by chemiluminescence. Furthermore, SNAP is stable in the E2As polymer, retaining 89% of the initial SNAP after ethylene oxide (EO) sterilization. The SNAP/E2As and E2As control catheters were implanted in sheep veins for 7 d to examine the effect on thrombosis and bacterial adhesion. The SNAP/E2As catheters reduced the thrombus area when compared to the control (1.56 ± 0.76 and 5.06 ± 1.44 cm2, respectively). A 90% reduction in bacterial adhesion was also observed for the SNAP/E2As catheters as compared to the controls. The results suggest that the SNAP/E2As polymer has the potential to improve the hemocompatibility and bactericidal activity of intravascular catheters, as well as other blood-contacting medical devices (e.g., vascular grafts, extracorporeal circuits).

The effect of a polyurethane coating incorporating both a thrombin inhibitor and nitric oxide on hemocompatibility in extracorporeal circulation.

Nitric oxide (NO) releasing (NORel) materials have been extensively investigated to create localized increases in NO concentration by the proton driven diazeniumdiolate-containing polymer coatings and demonstrated to improve extracorporeal circulation (ECC) hemocompatibility. In this work, the NORel polymeric coating composed of a diazeniumdiolated dibutylhexanediamine (DBHD-N2O2)-containing hydrophobic Elast-eon™ (E2As) polyurethane was combined with a direct thrombin inhibitor, argatroban (AG), and evaluated in a 4 h rabbit thrombogenicity model without systemic anticoagulation. In addition, the immobilizing of argatroban to E2As polymer was achieved by either a polyethylene glycol-containing (PEGDI) or hexane methylene (HMDI) diisocyanate linker. The combined polymer film was coated on the inner walls of ECC circuits to yield significantly reduced ECC thrombus formation compared to argatroban alone ECC control after 4 h blood exposure (0.6 ± 0.1 AG/HMDI/NORel vs 1.7 ± 0.2 cm(2) AG/HMDI control). Platelet count (2.8 ± 0.3 AG/HMDI/NORel vs 1.9 ± 0.1 × 10(8)/ml AG/HMDI control) and plasma fibrinogen levels were preserved after 4 h blood exposure with both the NORel/argatroban combination and the AG/HMDI control group compared to baseline. Platelet function as measured by aggregometry remained near normal in both the AG/HMDI/NORel (63 ± 5%) and AG/HMDI control (58 ± 7%) groups after 3 h compared to baseline (77 ± 1%). Platelet P-selectin mean fluorescence intensity (MFI) as measured by flow cytometry also remained near baseline levels after 4 h on ECC to ex vivo collagen stimulation (16 ± 3 AG/HMDI/NORel vs 11 ± 2 MFI baseline). These results suggest that the combined AG/HMDI/NORel polymer coating preserves platelets in blood exposure to ECCs to a better degree than AG/PEGDI/NORel, NORel alone or AG alone. These combined antithrombin, NO-mediated antiplatelet effects were shown to improve thromboresistance of the AG/HMDI/NORel polymer-coated ECCs and move potential nonthrombogenic polymers closer to mimicking vascular endothelium.

Family-based exposure and response prevention therapy for preschool-aged children with obsessive-compulsive disorder: a pilot randomized controlled trial.

AIMS: To examine the feasibility, acceptability and preliminary efficacy of family-based exposure/response prevention therapy (E/RP) versus treatment as usual (TAU) in a cohort of very young children with early onset obsessive-compulsive disorder (OCD). METHODS: Thirty-one children ages 3-8 years (M = 5.8 years) with a primary diagnosis of OCD were randomized to E/RP or TAU. The E/RP condition received 12 sessions of family-based E/RP twice weekly over 6 weeks. Families were assessed at baseline, post-treatment, 1-month and 3-month follow up. The Children's Yale Brown Obsessive Compulsive Scale and Clinical Global Impression served as primary outcome measures. RESULTS: A large group effect emerged in favor of the E/RP group (d = 1.69). Sixty-five percent of the E/RP group was considered treatment responders as compared to 7% in the TAU group. Symptom remission was achieved in 35.2% of the E/RP group and 0% of the TAU group. There was no attrition and satisfaction was high; gains were maintained at 3 months. CONCLUSIONS: Even amongst children as young as 3 years, developmentally tailored E/RP is efficacious and well-tolerated in reducing OCD symptoms. Key adaptations for younger children include extensive parent involvement, targeting family accommodation, and frequent meetings while delivering a full course of E/RP.

Defining clinical severity in pediatric obsessive-compulsive disorder.

Despite extensive use of the Children's Yale Brown Obsessive Compulsive Scale (CYBOCS; Scahill et al., 1997), the lack of normative data impedes interpretation of individual CYBOCS scores. Consequently, psychometrics on CYBOCS severity scores from 815 treatment-seeking youth with obsessive-compulsive disorder (OCD) are presented, across age and sex, so that normative comparisons of obsessive, compulsive, and combined obsessive-compulsive severity could be calculated. Our findings suggest no evidence for marked age or sex differences. Further, obsessive-compulsive symptom severity scores (measured via the CYBOCS) appear consistent with global OCD syndrome severity (measured via the Clinician Global Impression-Severity scale [CGI-S; Guy, 1976]; r = .58). This study contributes the 1st empirically based guidelines for interpreting obsessive-compulsive symptom severity scores. After a diagnosis of OCD is determined, the CYBOCS can be used to determine severity of illness (however, categories of severity proposed by this article should not be used in the screening of OCD symptoms). Findings can facilitate clinicians' and investigators' ability to draw comparisons across obsessive-compulsive severity scores.

The phenomenology and clinical correlates of suicidal thoughts and behaviors in youth with autism spectrum disorders.

This study investigated the phenomenology and clinical correlates of suicidal thoughts and behaviors in youth with ASD (N = 102; range 7-16 years). The presence of suicidal thoughts and behavior was assessed through the Anxiety Disorders Interview Schedule-Child and Parent Versions. Children and parents completed measures of anxiety severity, functional impairment, and behavioral and emotional problems. Approximately 11 % of youth displayed suicidal thoughts and behaviors. Children with autism were more likely to have suicidal thoughts and behaviors whereas children with Asperger's disorder were less likely. Suicidal thoughts and behaviors were associated with the presence of depression and post-traumatic stress disorder. Overall, results suggest that suicidal thoughts and behaviors are common in youth with ASD, and may be related to depression and trauma.

The effect of cognitive-behavioral therapy versus treatment as usual for anxiety in children with autism spectrum disorders: a randomized, controlled trial.

OBJECTIVE: To examine the efficacy of a modular cognitive-behavioral therapy (CBT) protocol relative to treatment as usual (TAU) among children with high-functioning autism spectrum disorders (ASD) and clinically significant anxiety. METHOD: A total of 45 children (7-11 years of age) with high-functioning ASD and clinically significant anxiety were randomized to receive 16 sessions of weekly CBT or TAU for an equivalent duration. After screening, assessments were conducted at baseline, post-treatment, and 3-month follow-up. Raters were blind to treatment condition. RESULTS: Youth receiving CBT showed substantial improvement relative to TAU on primary anxiety outcomes. Of 24 children randomized to the CBT arm, 18 (75%) were treatment responders, versus only 3 of 21 children (14%) in the TAU arm. Gains were generally maintained at 3-month follow-up for CBT responders. CONCLUSIONS: Relative to usual care, CBT adapted for anxious youth with high-functioning ASD demonstrates large effects in reducing anxiety symptoms. This study contributes to the growing literature supporting adapted CBT approaches for treating anxiety in youth with ASD.

Psychometric properties of the obsessive compulsive inventory: child version in children and adolescents with obsessive-compulsive disorder.

The psychometric properties of the Obsessive Compulsive Inventory-Child Version (OCI-CV) were examined in ninety-six youth with a primary/co-primary diagnosis of obsessive-compulsive disorder (OCD). A confirmatory factor analysis revealed an acceptable model of fit with factors consisting of doubting/checking, obsessing, hoarding, washing, ordering, and neutralizing. The internal consistency of the OCI-CV total score was good, while internal consistency for subscale scores ranged from poor to good. The OCI-CV was modestly correlated with obsessive-compulsive symptom severity on the Children's Yale-Brown Obsessive Compulsive Scale (CY-BOCS) Severity Scale, as well as with clinician-reported OCD severity. All OCI-CV subscales significantly correlated with the corresponding CY-BOCS Symptom Checklist dimension. The OCI-CV significantly correlated with child-reported depressive symptoms and OCD-related functional impairment, but was not significantly correlated with parent-reported irritability or clinician-reported overall functioning. Taken together, these data suggest the psychometric properties of the OCI-CV are adequate for assessing obsessive-compulsive symptom presence among youth with OCD.

Multiple informant agreement on the anxiety disorders interview schedule in youth with autism spectrum disorders.

OBJECTIVE: The purpose of this study was to examine child, parent, and clinician's consensus agreement on the Anxiety Disorders Interview Schedule, Child and Parent versions (ADIS-C/P) in a sample of children and adolescents with autism spectrum disorders (ASD). METHOD: Youth with ASD (n=85; age range=7-17 years) and their parents were each administered the ADIS-C/P by a trained clinician. Consensus diagnoses were determined in a clinical conference using best estimate procedures that incorporated all available information. RESULTS: Children and youth with ASD diagnoses generally showed poor diagnostic agreement with parents and clinical consensus, whereas parents showed good-to-excellent diagnostic agreement with clinical consensus diagnoses. Diagnostic agreement between parents and consensus was moderated by the specific ASD diagnosis. Otherwise, the pattern of relationships did not systematically differ as a function of age or externalizing comorbidity. CONCLUSIONS: These data suggest that parent and youth agreement regarding the presence of clinical levels of anxiety is markedly poor among youth with ASD. Additionally, clinicians are likely to base their diagnostic impressions on parent report, placing minimal emphasis on child report.

Rage attacks in pediatric obsessive-compulsive disorder: phenomenology and clinical correlates.

OBJECTIVE: Rage attacks have been documented in youth with varied psychiatric disorders, but few data have been reported on the clinical characteristics and correlates of rage attacks among children with obsessive-compulsive disorder (OCD). METHOD: Participants were 86 children (ages 6-16 years) with a primary diagnosis of OCD. Patients and their primary caregiver were administered clinician-rated measures of obsessive-compulsive severity and rage severity. Children completed the Center for Epidemiologic Studies Depression Scale and the Child Sheehan Disability Scale-Child, whereas parents completed the Rage Attacks Questionnaire, Aberrant Behavior Checklist-Irritability Scale, Children's Affective Lability Scale, and Child Sheehan Disability Scale-Parent. RESULTS: Rage was common among youth with OCD and was associated with varied clinical characteristics. Rage severity accounted for functional impairment beyond the influence of obsessive-compulsive symptom severity; however, these relations were explained by the impact of family accommodation. CONCLUSIONS: These data suggest that rage attacks are relatively common, have a negative impact on illness presentation, and contribute to functional impairment above and beyond obsessive-compulsive symptom severity. Rage may contribute to family accommodation of symptoms, which may further affect obsessive-compulsive symptom severity and impairment.

The role of co-occurring disruptive behavior in the clinical presentation of children and adolescents with anxiety in the context of autism spectrum disorders.

This study explored the impact of disruptive behavior disorder (DBD) comorbidity on theoretically relevant correlates among 87 children and adolescents with autism spectrum disorders (ASD) and clinically significant anxiety. Relative to youth with ASD and anxiety alone, participants with ASD, anxiety, and DBD: (a) presented with significantly more severe anxiety symptoms per clinician-, parent-, and self-report; (b) were more likely to be prescribed antipsychotic medication but were no more likely to receive additional psychosocial and educational interventions; and (c) experienced significantly greater functional impairment and family interference. These results suggest that co-occurring DBD in the context of ASD and anxiety confers greater risk for heightened symptom severity and functional impairment, and may be linked with increased prescription of antipsychotic medication.

Convergent and discriminant validity and reliability of the pediatric anxiety rating scale in youth with autism spectrum disorders.

The psychometric properties of the Pediatric Anxiety Rating Scale (PARS), a clinician-administered measure for assessing severity of anxiety symptoms, were examined in 72 children and adolescents diagnosed with an autism spectrum disorder (ASD). The internal consistency of the PARS was 0.59, suggesting that the items were related but not repetitive. The PARS showed high 26-day test-retest (ICC = 0.83) and inter-rater reliability (ICC = 0.86). The PARS was strongly correlated with clinician-ratings of overall anxiety severity and parent-report anxiety measures, supporting convergent validity. Results for divergent validity were mixed. Although the PARS was not associated with the sum of the Social and Communication items on the Autism Diagnostic Observation System, it was moderately correlated with parent-reported inattention, aggression and externalizing behavior. Overall, these results suggest that the psychometric properties of the PARS are adequate for assessing anxiety symptoms in youth with ASD, although additional clarification of divergent validity is needed.

Defining treatment response in pediatric tic disorders: a signal detection analysis of the Yale Global Tic Severity Scale.

OBJECTIVE: To examine the optimal Yale Global Tic Severity Scale (YGTSS) percent reduction and raw cutoffs for predicting treatment response among children and adolescents with tic disorders. METHOD: Youth with a tic disorder (N=108; range=5-17 years) participated in several clinical trials involving varied medications or psychosocial treatment, or received naturalistic care. Assessments were conducted before and after treatment and included the YGTSS and response status on the Clinical Global Impressions-Improvement Scale (CGI-I). RESULTS: A 35% reduction on the YGTSS total tic severity score or a YGTSS raw total tic severity score change of 6 or 7 points were the best indicators of clinical treatment response in youth with tic disorders. CONCLUSIONS: A YGTSS total tic severity score reduction of 35% or a raw total tic severity score change of 6 or 7 appears optimal for determining treatment response. A consistent definition of treatment response on the YGTSS may facilitate cross-study comparability. Practitioners can use these values for treatment planning decisions (e.g., change medications, etc.).
