Expectations and perspectives of cognitive behavioural therapy for childhood anxiety and related disorders.

BACKGROUND: Anxiety disorders are the most frequently diagnosed psychiatric conditions in children and adolescents. Cognitive behavioural therapy (CBT) is a well-established and effective treatment for anxiety and related disorders across the lifespan. Expectations of psychotherapy have been demonstrated to affect outcomes, yet there is sparse existing literature on adolescent patient and parent perspectives of CBT prior to engagement with treatment. AIMS: This study aimed to qualitatively explore the expectations and perceptions of CBT for anxiety and related disorders among adolescent patients and parents. METHOD: Fourteen adolescent patients and 16 parents participated in semi-structured individual interviews or focus groups consisting of 2-3 participants. Interview transcripts were analysed using inductive analysis. RESULTS: Three themes were identified: worries about CBT, expectations and knowledge of the CBT process, and the role of parents and families. Overall, we found that adolescents and parents had generally positive views of CBT. The outset of CBT saw adolescents and parents express concern about stigma as well as the ambiguity of CBT. Parents continued to express a lack of understanding of what CBT entailed during their child's treatment course. CONCLUSION: These results suggest that both adolescents and parents would benefit from early discussion and reinforcement of expectations for CBT treatment. Further research efforts are warranted and should be directed towards determining appropriate expectations for parental involvement in a child's CBT course and effective communication of treatment expectations to both adolescents and parents.

Assessing the predictors of adaptive and maladaptive Covid-19 preventive behaviours: an application of protection motivation theory.

Despite the high death toll of the COVID-19 pandemic, reported rates of adherence to adaptive preventive health behaviours during the early wave of the pandemic were suboptimal for reducing the risk of disease spread. Additionally, some have adopted practices with the intention of preventing infection that have harmful consequences. Protection Motivation Theory (PMT), consisting of perceived vulnerability, severity, response efficacy, and self-efficacy, has been used to predict intentions to engage in behaviours in past pandemics, and can be extended to the COVID-19 outbreak. Three hundred and thirty-three American adults completed a survey in May 2020 through Amazon's Mechanical Turk. Ten behaviours recommended by the CDC and WHO and two 'maladaptive' behaviours presented in the media were selected for investigation. Binary logistic regressions were conducted to assess the impacts of demographic variables and PMT constructs on behaviour frequency. Perceived severity and vulnerability were not significant predictors of behaviour frequency. Behaviour specific response efficacy and self-efficacy were significant predictors of 11/12 (odds ratios: 2.70-6.22) and 10/12 (odds ratios: 2.59-4.64) behaviours, respectively. Age, gender, education, political ideology, perceived severity, and perceived vulnerability were generally unimportant predictors. Beliefs about the effectiveness of the behaviour and one's ability to carry out that behaviour consistently seem to be more important in predicting how often someone engages in that behaviour than the perceived dangerousness of COVID-19 and one's believed susceptibility to infection. These results suggest that interventions trying to modulate the likelihood of engaging in preventive behaviours should focus on the effectiveness of these behaviours in reducing risk of spread and the individual's ability to engage in these behaviours frequently rather than the dangerousness of the COVID-19 pandemic and the individual's risk of becoming infected.

Approach and Avoidance Coping Dynamics during the COVID-19 Pandemic.

Approach-avoidance conflicts were one of the earliest applications of catastrophe theory. Empirical studies evaluating the cusp catastrophe model for approach-avoidance dynamics have only started to appear recently, however. The present study reviews the extant research and expands the concept to approach and avoidance coping styles. Research participants were 333 adults from the general population recruited through Amazon Mechanical Turk. They completed measures of psychological symptoms, quality of life (QOL), approach and avoidance coping styles, and COVID-related stress. Cusp models for symptoms (R2 = .84) and QOL (R2 = .89) illustrated approach and avoidance functioning as bifurcation gradients for both psychological symptoms and QOL. Both models provided more accurate representations of the data than the linear alternatives (R2 = .54 and .24 respectively), thus providing further support for the cusp dynamics. The cusp catastrophe model has extensive applicability to approach-avoidance behaviors. There was greater variability (hysteresis) in outcomes for people who used fewer coping strategies of either the approach or avoidance types.

Sleep Discrepancy in a Randomized Controlled Trial of Brief Behavioral Therapy for Chronic Insomnia in Older Adults.

Background/Objective: Some older adults with insomnia experience sleep discrepancy, often characterized by greater subjective sleep difficulties and shorter subjective sleep duration than the estimates derived from objective measures. The present study examined whether a brief behavioral therapy for insomnia (BBTi) is efficacious for reducing sleep discrepancy in older adults. Methods: This study is a secondary analysis of a randomized controlled trial of BBTi for community dwelling older adults with chronic insomnia (N = 62). Thirty-two participants received BBTi, delivered in four individual face-to-face sessions. Thirty received the self-monitoring control (SMC). They all completed daily sleep diaries and wore an actigraph from baseline to posttreatment, and for 2 weeks at 3-month follow-up. Sleep discrepancy was calculated by subtracting diary from actigraphy estimates of sleep onset latency (SOL), wake after sleep onset (WASO), and total sleep time (TST). Mixed modeling was used to analyze data. SOL discrepancy decreased significantly in BBTi participants compared to SMC participants. The decreases in SOL discrepancy were explained by changes in diary-assessed SOL and subjective sleep quality but not changes in actigraphy-assessed SOL. Although WASO discrepancy and TST discrepancy decreased from baseline to posttreatment and follow-up, the Time by Group interaction effects were not significant indicating that BBTi participants did not experience greater reductions in WASO discrepancy and TST discrepancy than SMC participants. In conclusion, BBTi is efficacious for reducing SOL discrepancy in older adults with chronic insomnia.

Effects of Brief Behavioral Treatment for Insomnia on Daily Associations between Self-Reported Sleep and Objective Cognitive Performance in Older Adults.

OBJECTIVE: Behavioral treatments for insomnia improve sleep in older adults, but research documenting their effects on cognitive performance is mixed. We explored whether a brief behavioral treatment for insomnia (BBTi) impacts daily associations between sleep parameters and next day cognition. METHODS: Sixty-two older adults (Mage = 69.45 years, SD = 7.71) with insomnia completed either 4 weeks of BBTi or self-monitoring control (SMC). At baseline, post-treatment, and 3 month follow-up, participants completed 14 days of diaries measuring sleep onset latency (SOL), wake after sleep onset (WASO), total sleep time (TST), and sleep efficiency (SE), as well as daily cognitive tests measuring processing speed (i.e., symbol digit modalities test, SDMT), and reasoning (i.e., letter series). At each time period, associations between sleep parameters and daily cognition, controlling for age, education, insomnia duration, use of sleep medications, and depression (i.e., Beck Depression Inventory-2nd Edition scores), were examined through multilevel modeling. RESULTS: At post-treatment, we observed an interactive fixed effect of treatment condition (i.e., BBTi/SMC) and TST on daily SDMT and letter series performance. For BBTi, longer TST was associated with better letter series performance, and did not predict SDMT performance. For SMC, longer TST was associated with worse SDMT, and was not associated with letter series performance. Greater WASO (regardless of group) was associated with better SDMT performance at post-treatment. Associations were not maintained at follow-up. CONCLUSIONS: Sleep duration may play an important role in BBTi-related improvements in daily higher order cognition. Maintenance of these associations may be facilitated by booster sessions following post-treatment. CLINICAL TRIAL IDENTIFIER: NCT02967185.

Parents' Perceptions of Internalizing and Externalizing Features in Childhood OCD.

Although obsessive-compulsive disorder (OCD) has often been characterized as an internalizing disorder, some children with OCD exhibit externalizing behaviors that are specific to their OCD. This study sought to demonstrate that parents perceive both internalizing and externalizing behaviors in childhood OCD by examining the factor structure of the Child Obsessive-Compulsive Externalizing/Internalizing Scale (COCEIS), a parent-report questionnaire intended to measure these constructs. This study also investigated clinical correlates of internalizing and externalizing factors in the COCEIS. A factor analysis of questionnaire responses from 122 parents of youth with OCD revealed both externalizing and internalizing factors in the COCEIS. Externalizing behaviors in childhood OCD were associated with other, co-occurring externalizing behavior problems, while both factors were positively correlated with OCD severity and co-occurring internalizing symptoms. They were positively associated with each other at a trend level, and neither showed a significant relationship with insight. Sixty-two percent of parents endorsed "often" or "always" to at least one externalizing item, though modal responses to items suggested that each individual feature captured by the COCEIS may be relatively uncommon. Mean responses were significantly greater for internalizing items. This study provides evidence for distinct but related externalizing and internalizing behaviors specific to childhood OCD. Treatment for children with OCD presenting with more externalizing behaviors may require a greater emphasis on behavioral parent training and motivational enhancement.

Group exposure and response prevention for college students with social anxiety: A randomized clinical trial.

OBJECTIVE: Social anxiety increases college student drop-out risk and stifles employment opportunities. Group cognitive-behavioral therapy with exposure (CBT ERP) has the potential to alleviate campus resource strain but remains under-researched with college students. The present study investigated the efficacy of group CBT ERP in a randomized clinical trial on a college campus. METHOD: Thirty-one postsecondary students were randomly assigned to an exposure-only group or an active control. RESULTS: Linear mixed-effects models indicated significant Group × Time interactions for general social anxiety (t = -2.02, g = 0.62) and depression (t = -2.77, g = 0.55); nonsignificant main effects were found for group and time variables. On a measure of fear of negative evaluation, only the main effect of time was significant (t = 2.15, p = 0.032). CONCLUSIONS: When compared to an active control group, CBT ERP is an efficacious and time-effective treatment for college students experiencing social anxiety.

Sinusoidal Obstruction Syndrome During Maintenance Therapy for Acute Lymphoblastic Leukemia With 6-Mercaptopurine and Methotrexate: A Pediatric Case Report.

We report a case of a child with pre-B cell acute lymphoblastic leukemia undergoing maintenance chemotherapy with 6-mercaptopurine and methotrexate (MTX) who developed sinusoidal obstruction syndrome after being treated with ciprofloxacin for BK viremia. This case represents a rare complication of maintenance therapy with MTX and 6-mercaptopurine, and suggests a drug interaction between ciprofloxacin and MTX.

Common Barriers to the Dissemination of Exposure Therapy for Youth with Anxiety Disorders.

This study investigated the prevalence of common barriers to the use of exposure therapy (ET) in the treatment of youth with anxiety disorders, specifically examining both logistical limitations and negative beliefs about ET. Results from 230 practicing clinicians who treat youth with anxiety disorders found that the top three barriers were session length (56%), lack of training (48%), and concern about parent reaction (47%). Endorsement of barriers to ET was associated with less ET utilization and less optimal implementation of ET. Results suggest that several barriers, especially logistical limitations, must be addressed in order to improve the dissemination of ET.

Modeling the respiratory motion of solitary pulmonary nodules and determining the impact of respiratory motion on their detection in SPECT imaging.

The objectives of this investigation were to model the respiratory motion of solitary pulmonary nodules (SPN) and then use this model to determine the impact of respiratory motion on the localization and detection of small SPN in SPECT imaging for four reconstruction strategies. The respiratory motion of SPN was based on that of normal anatomic structures in the lungs determined from breath-held CT images of a volunteer acquired at two different stages of respiration. End-expiration (EE) and time-averaged (Frame Av) non-uniform-B-spline cardiac torso (NCAT) digital-anthropomorphic phantoms were created using this information for respiratory motion within the lungs. SPN were represented as 1 cm diameter spheres which underwent linear motion during respiration between the EE and end-inspiration (EI) time points. The SIMIND Monte Carlo program was used to produce SPECT projection data simulating Tc-99m depreotide (NeoTect) imaging. The projections were reconstructed using 1) no correction (NC), 2) attenuation correction (AC), 3) resolution compensation (RC), and 4) attenuation correction, scatter correction, and resolution compensation (AC_SC_RC). A human-observer localization receiver operating characteristics (LROC) study was then performed to determine the difference in localization and detection accuracy with and without the presence of respiratory motion. The LROC comparison determined that respiratory motion degrades tumor detection for all four reconstruction strategies, thus correction for SPN motion would be expected to improve detection accuracy. The inclusion of RC in reconstruction improved detection accuracy for both EE and Frame Av over NC and AC. Also the magnitude of the impact of motion was least for AC_SC_RC.

LROC Investigation of Three Strategies for Reducing the Impact of Respiratory Motion on the Detection of Solitary Pulmonary Nodules in SPECT.

The objective of this investigation was to determine the effectiveness of three motion reducing strategies in diminishing the degrading impact of respiratory motion on the detection of small solitary pulmonary nodules (SPN) in single photon emission computed tomographic (SPECT) imaging in comparison to a standard clinical acquisition and the ideal case of imaging in the absence of respiratory motion. To do this non-uniform rational B-spline cardiac-torso (NCAT) phantoms based on human-volunteer CT studies were generated spanning the respiratory cycle for a normal background distribution of Tc-99m NeoTect. Similarly, spherical phantoms of 1.0 cm diameter were generated to model small SPN for each of 150 uniquely located sites within the lungs whose respiratory motion was based on the motion of normal structures in the volunteer CT studies. The SIMIND Monte Carlo program was used to produce SPECT projection data from these. Normal and single-lesion containing SPECT projection sets with a clinically realistic Poisson noise level were created for the cases of: 1) the end-expiration (EE) frame with all counts, 2) respiration-averaged motion with all counts, 3) one-fourth of the 32 frames centered around EE (Quarter-Binning), 4) one-half of the 32 frames centered around EE (Half-Binning), and 5) eight temporally binned frames spanning the respiratory cycle. Each of the sets of combined projection data were reconstructed with RBI-EM with system spatial-resolution compensation (RC). Based on the known motion for each of the 150 different lesions, the reconstructed volumes of respiratory bins were shifted so as to superimpose the locations of the SPN onto that in the first bin (Reconstruct and Shift). Five human-observers performed localization receiver operating characteristics (LROC) studies of SPN detection. The observer results were analyzed for statistical significance differences in SPN detection accuracy among the three correction strategies, the standard acquisition, and the ideal case of the absence of respiratory motion. Our human-observer LROC determined that Quarter-Binning and Half-Binning strategies resulted in SPN detection accuracy statistically significantly below (P < 0.05) that of standard clinical acquisition, whereas the Reconstruct and Shift strategy resulted in a detection accuracy not statistically significantly different from that of the ideal case. This investigation demonstrates that tumor detection based on acquisitions associated with less than all the counts which could potentially be employed may result in poorer detection despite limiting the motion of the lesion. The Reconstruct and Shift method results in tumor detection that is equivalent to ideal motion correction.

The diabetes online community: the importance of forum use in parents of children with type 1 diabetes.

Online forums for chronic health conditions emerged as early as 30 yr ago and interest in their study has blossomed. Type 1 diabetes (T1D) forums have grown exponentially since 2005. Therefore, a comprehensive evaluation of these forums is needed. This study assesses the demographics and motivations of parents who use type 1 diabetes forums and the potential impact that forum membership (FM) has on parenting stress and hypoglycemic fear. One hundred and two parents were recruited through online T1D forums and asked to complete qualitative and quantitative measures of their experience with the T1D forums. Results of this study suggest that parents who use T1D forums mirror those who participate in clinic-based research protocols and are primarily motivated to participate in forums to increase their diabetes knowledge and gain social support. Indeed, parents who use T1D forums report high levels of trust, social support, and perceived knowledge gained. However, FM was positively related to increased self-reported parenting stress frequency and hypoglycemic fear behaviors. Taken together, the relationships formed within these communities may have a significant impact on the experience of these caregivers. The need for future research and potential implications for physicians, including parent debriefing, are discussed.

Congenital kaposiform hemangioendothelioma with Kasabach-Merritt phenomenon successfully treated with low-dose radiation therapy.

Kaposiform hemangioendothelioma (KHE) associated with Kasabach-Merritt phenomenon is a life-threatening vasculopathy. The current mainstay treatment for KHEs is corticosteroids and chemotherapy, but these medications do not work for all patients and carry significant side effects. We report a neonate with a large congenital KHE who responded extremely well to low-dose radiation therapy.

Sleep disturbances associated with cigarette smoking.

Sleep disturbances resulting in insufficient sleep have been linked to negative physical, cognitive, and public health outcomes. Despite this, there has yet a study that examines the impact of smoking on sleep in a US based national sample. The current study sought to observe sleep disturbances associated with smoking status. Sleep disturbances in adults aged 20 years and above, from the 2005-2006 National Health and Nutrition Examination Survey, were measured among current, former, and never smokers (NS). Current smokers (CS) reported significantly less total sleep time, longer sleep onset latency, increased difficulty falling asleep, maintaining sleep, and waking up earlier than desired when compared to NS. Former smokers reported disturbances similar to NS and CS experienced poorer sleep than nonsmokers. Our study is the first to observe sleep difficulty by smoking status in a large, population-based, nationally representative sample. Recommendations for smoking cessation programs are discussed.

Prospective relationship between obsessive-compulsive and depressive symptoms during multimodal treatment in pediatric obsessive-compulsive disorder.

The present study examined the prospective relationship between obsessive-compulsive and depressive symptoms during a multimodal treatment study involving youth with obsessive-compulsive disorder (OCD). Participants included fifty-six youth, aged 7-17 years (M = 12.16 years) who were enrolled in a two-site randomized controlled pharmacological and cognitive behavioral therapy treatment trial. Obsessive-compulsive severity was measured using the Children's Yale-Brown Obsessive-Compulsive Scale, and depressive symptoms were rated using the Children's Depression Rating Scale-Revised. Multi-level modeling analyses indicated that, on average over the course of treatment, variable and less severe obsessive-compulsive symptoms significantly predicted a decrease in depressive symptoms. Additionally, week-to-week fluctuations in OCD severity did not significantly predict weekly changes in depressive symptom severity. Level of baseline depressive symptom severity did not moderate these relationships. Findings suggest that when treating youth with OCD with co-occurring depression, therapists should begin by treating obsessive-compulsive symptoms, as when these are targeted effectively, depressive symptoms diminish as well.

Implementation and Preliminary Outcomes of an Exposure-Based Summer Camp for Pediatric OCD and Anxiety.

Despite the high prevalence of anxiety disorders in children and adolescents and the existence of effective evidence-based treatments for them, access to psychological care remains a major public health concern. Summer camps may provide an effective treatment avenue for youth who might not otherwise have access to care. This study describes the design and implementation of Fear Facers, a semistructured, 5-day, daytime exposure-therapy-based summer camp designed for youth with a primary diagnosis of obsessive-compulsive disorder (OCD), social anxiety, separation anxiety, or a specific phobia. Preliminary data regarding feasibility and patient outcomes is also reported. Among 52 children and adolescents aged 7 to 16 who attended one of six camp sessions between 2018 and 2021, significant reductions in anxiety (d = 0.54) and OCD symptoms (d = 0.57) were observed from pre-camp to immediately post-camp. A subset of campers who were followed for an additional 3 months post-camp (n = 22) showed maintenance of treatment gains. Retention rates for the intervention were high. Our investigation provides further support for the use of a camp-based design for cognitive-behavioral approaches, and may provide a unique setting to maximize elements of inhibitory learning in exposures. We also discuss a number of elements regarding feasibility that need consideration for those hoping to develop similar interventions.

Relationships between stress appraisals and intolerance of uncertainty with psychological health during early COVID-19 in the USA.

BACKGROUND AND OBJECTIVES: The COVID-19 pandemic has caused increased psychological distress and decreased quality of life (QoL), but limited research has evaluated cognitive appraisals of COVID-19. This study aimed to examine the role of three stress appraisals of the COVID-19 pandemic - threat appraisal, harm/loss appraisal, and challenge appraisal - and the interaction between these appraisals and intolerance of uncertainty (IU) on psychological distress and QoL. DESIGN: This was a cross-sectional survey study using Amazon's Mechanical Turk. METHODS: A sample of 327 adults living in the U.S. completed a series of questionnaires investigating IU, appraisal of the pandemic, psychological distress, and QoL in May 2020 during the first wave of the COVID-19 pandemic. RESULTS: Controlling for demographic variables, IU and harm/loss appraisal positively related to psychological distress and negatively related to QoL. Challenge appraisals negatively related to distress and positively related to QoL. Moderation analyses revealed that higher levels of IU led to stronger positive relationships between threat appraisal and psychological distress. CONCLUSIONS: Cognitive appraisals of COVID-19 are associated with psychological health, though the relationship between threat appraisal and psychological distress are strongest for those with difficulty tolerating uncertainty. Theoretical and practical implications are discussed.

An examination of obsessive-compulsive symptom domains, depression, and quality of life within an online survey sample.

Obsessive-compulsive disorder (OCD) is a heterogeneous and highly impairing disorder that is frequently comorbid with other conditions. Participants in this study were 212 individuals recruited through Mechanical Turk who filled out validated measures of obsessive-compulsive symptoms, quality of life (QoL), generalized anxiety, and depressive symptoms. Analyses examined the influences of each symptom variable on QoL and the mediating role of depression as an indirect link between unacceptable thoughts (UT) and QoL. Depressive symptoms had a significant negative relationship with multiple domains of functioning. Generalized anxiety was not significant. Higher endorsement of UT symptoms was related to lower physical, emotional, and social QoL. Depression partially mediated the relationship between UT symptoms and physical, emotional, and social health. Depressive symptoms are important to consider in clinical work surrounding OCD. The significant associations between UT symptoms and QoL in a nonclinical population illustrate a relevant area for future intervention, public awareness, and education.

Acute constipation in children receiving chemotherapy for cancer.

BACKGROUND: Constipation occurs in children receiving chemotherapy for cancer but there are no data about prevalence, risk factors, and severity of constipation in this group of children. METHODS: We prospectively studied 61 children receiving chemotherapy for cancer. We administered questionnaires to children and parents and collected data on demographics, chemotherapy, and bowel movement pattern during chemotherapy. We used North American Society of Pediatric Gastroenterology, Hepatology, and Nutrition criteria for the diagnosis of constipation. Parental perception of constipation as a problem and impact on lifestyle during chemotherapy were assessed on a 0 to 3 scale with 0 being no problem, 1 minor, 2 significant, and 3 being a major problem. RESULTS: Thirty-five children (57%) had acute constipation lasting for 2 or more weeks during chemotherapy. Several risk factors were analyzed and only combined use of vincristine and opiates emerged as significant risk factor for the development of constipation. In children with constipation, 15 of 35 parents (43%) perceived constipation as a major/significant problem and 8 children and their parents (23%) perceived constipation having a major/significant impact on lifestyle during chemotherapy. CONCLUSIONS: Acute constipation was diagnosed in 57% of children receiving chemotherapy for cancer. Combined use of vincristine and opiates was associated with the development of constipation. Constipation can be a significant problem with a negative impact on lifestyle during chemotherapy and needs aggressive management.

Atypical behaviors and comorbid externalizing symptoms equally predict children with attention-deficit/hyperactivity disorder's social functioning.

The goal of the current study was to determine within a clinical sample what differentiates children with ADHD who experience social functioning difficulties from those who appear to have healthy social functioning. Participants for this study included 62 children (mean age = 11.3 years) with a DSM-IV diagnosis of ADHD confirmed by a comprehensive clinical diagnostic assessment. Multiple indicators of children's social functioning were collected via parent report including: social skills, social adaptability, peer difficulties, and social quality of life. Parent reports of children's externalizing, internalizing, and atypical behaviors were also collected. Results indicated that both externalizing symptoms and atypical behaviors predicted children with ADHD's social functioning, even after controlling for ADHD symptoms severity. No association was found between internalizing symptoms and social functioning. The current study provides initial data suggesting that atypical behaviors found in children with ADHD are as powerful as comorbid externalizing symptoms in predicting social functioning difficulties. Due to the shared variance from relying solely on parent report, it will be critical for future research to replicate our findings using multi-informant data such as peer and teacher reports which provide unique information on children's social functioning.
