RESUMO
INTRODUCTION: Transgender and gender-diverse (TGD) youth experience more stressors and are therefore at a higher risk of health problems compared with their cisgender peers. The aim of this study was to investigate the prevalence of TGD youth in a general population sample and to explore a wide variety of health-related factors. We investigate differences in stressors and health outcomes between TGD youth and cisgender girls and boys and the influence of stressors and demographic factors on health outcome in the whole group. METHODS: Cross-sectional survey data from a Swedish school-based study were used (N = 3,067, M = 17.8 years). Those who had reported their gender identity as "other" or other than their assigned gender (N = 41) were compared with cisgendered girls (n = 1,544) and boys (n = 1,482). Regression models in the whole group explored if demographics and stressors statistically predicted health outcomes. RESULTS: In comparison with cisgender girls and boys, TGD youth (1.3% of the whole sample) reported a higher prevalence of self-harm and pain problems. Both TGD youth and cisgender girls more frequently reported insomnia, social anxiety, depressive symptoms, pain, and stressors compared with cisgender boys. When only demographic variables were entered, but not when stressors were added to the model, being TGD magnified the odds of depressive symptoms, sub-diagnostic social anxiety, and pain problems. Stressors magnified the odds of reporting health problems for the whole group. CONCLUSION: TGD youth generally reported more stressors, which negatively influence health outcomes. Results are important for professionals who meet TGD youth.
RESUMO
The Alabama parenting questionnaire (APQ) is a commonly used instrument for assessing parenting practices and evaluating treatment outcomes of parent-training interventions targeting child conduct problems. In the present study we translated and developed a Swedish version of the APQ parent version and tested it on a community sample of 799 parents of children between 6 and 15 years with diverse socioeconomic backgrounds. Data were collected through an online survey distributed through school newsletters and social media. Exploratory factor analysis (EFA) suggested a five-factor model with 23 items. Four of these factors correspond to the subscales suggested in the original version of the APQ: inconsistent discipline, poor monitoring, involvement, and positive parenting. The fifth subscale from the original APQ, corporal punishment, did not show up as a factor in our data sample. Instead, a new factor, which we refer to as contingency management, was revealed. A confirmatory factor analysis further suggested some misalignment between the original APQ subscale structure and our sample, which we interpret as a signal that the instrument may need refinement to better reflect contemporary parenting methods in diverse cultural contexts. Despite this limitation, and with the exclusion of the corporal punishment subscale, which should be employed judiciously, our results suggest that the Swedish version of the APQ can be a useful instrument in measuring parenting practices in Sweden. We present norm data stratified by child age, which practitioners and researchers can use as a reference for assessment of parenting practices in the Swedish population.

Parent training is an effective treatment for disruptive behavior problems in children. However, as there is limited access to traditional face-to-face treatment, other delivery formats have been evaluated. This study aims to evaluate possible predictors and moderators of outcome, completion and engagement in parent training when delivered in group or through the internet. A recent randomized controlled non-inferiority trial (N = 161) demonstrated equal effectiveness of the parent training program Comet when delivered in group (gComet) and through the internet (iComet). Demographic, clinical and theory-driven variables were studied to find predictors and moderators of treatment effect, completion and engagement. Linear mixed effects models were used to determine predictors and moderators of change in disruptive behavior from baseline to the 3- and 12-month follow-up. Most variables did not have significant predictive or moderating effects. However, there were some variables that predicted or moderated outcomes that may have implications for practice (e.g., comorbid emotional problems, preferred treatment format, and ADHD). This trial can contribute to guiding clinical work with children with disruptive behavior and results indicate that parent training in both treatment formats can be offered regardless of a range of demographic and clinical factors. Taking patients' treatment preferences into account can increase treatment completion.

OBJECTIVE: To evaluate if an internet-delivered parent training program is noninferior to its group-delivered counterpart in reducing child disruptive behavior problems (DBP). METHOD: This noninferiority randomized clinical trial enrolled families seeking treatment in primary care in Stockholm, Sweden, for DBP in a child 3-11 years of age. Participants were randomized to internet-delivered (iComet) or group-delivered (gComet) parent training. The primary outcome was parent-rated DBP. Assessments were made at baseline and 3, 6, and 12 months. Secondary outcomes included child and parent behaviors and well-being and treatment satisfaction. The noninferiority analysis was determined by a one-sided 95% CI of the mean difference between gComet and iComet using multilevel modeling. RESULTS: This trial included 161 children (mean age 8.0); 102 (63%) were boys. In both intention-to-treat and per-protocol analyses, iComet was noninferior to gComet. There were small differences in between-group effect sizes (d = -0.02 to 0.13) on the primary outcome with the upper limit of the one-sided 95% CI below the noninferiority margin at 3-, 6-, and 12-month follow-up. Parents were more satisfied with gComet (d = 0.49, 95% CI [0.26, 0.71]). At 3-month follow-up, there were also significant differences in treatment effect on attention-deficit/hyperactivity disorder symptoms (d = 0.34, 95% CI [0.07, 0.61]) and parenting behavior (d = 0.41, 95% CI [0.17, 0.65]) favoring gComet. At 12-month follow-up, there were no differences in any outcomes. CONCLUSION: Internet-delivered parent training was noninferior to group-delivered parent training in reducing child DBP. The results were maintained at 12-month follow-up. This study supports internet-delivered parent training being used as an alternative to group-delivered parent training in clinical settings.

Williams syndrome (WS) is a rare genetic condition associated with high sociability, intellectual disability, and social cognitive challenges. Attention to others' eyes is crucial for social understanding. Orienting to, and from other's eyes was studied in WS (n = 37, mean age = 23, age range 9-53). The WS group was compared to a typically developing comparison participants (n = 167) in stratified age groups from infancy to adulthood. Typically developing children and adults were quicker and more likely to orient to eyes than the mouth. This bias was absent in WS. The WS group had reduced peak saccadic velocities, indicating hypo-arousal. The current study indicates reduced orienting to others' eyes in WS, which may affect social interaction skills.

Internet-delivered cognitive behavioural therapy (ICBT) is an efficacious treatment for social anxiety disorder (SAD) in youth. However, we have limited knowledge about patient characteristics that may be associated with better (or worse) treatment outcome. Particularly concerning factors suggested to be involved in the maintenance of SAD (e.g., anticipatory anxiety and post-event processing). The aim of the current study was to evaluate possible predictors and moderators of the effect of ICBT in a randomised controlled trial where children and adolescents (N = 103; 10-17 years) with SAD received either ICBT or internet-delivered supportive therapy, ISUPPORT. Examined variables were pre-treatment levels of social anxiety, depression symptoms, putative maintaining factors as well as demographic variables like age and gender. Latent growth curve models were used to examine predictors and moderators of changes in youth and clinician rated social anxiety symptoms, from pre-treatment to 3-month follow-up. Baseline depression symptoms moderated the outcome, with higher depression scores being associated with greater reduction of SAD symptoms in ICBT compared to ISUPPORT. More difficulties at baseline with anticipatory anxiety, post-event processing, focus of attention and safety behaviours predicted greater reduction of SAD symptoms, regardless of treatment condition. No other clinical or demographic variable predicted or moderated the outcome. In summary, baseline depression severity may be an important moderator of ICBT, but the preliminary finding needs replication in sufficiently powered trials.

OBJECTIVES: In the International Classification of Diseases, Tenth Edition (ICD-10), hypochondriasis (illness anxiety disorder) and dysmorphophobia (body dysmorphic disorder) share the same diagnostic code (F45.2). However, the Swedish ICD-10 allows for these disorders to be coded separately (F45.2 and F45.2A, respectively), potentially offering unique opportunities for register-based research on these conditions. We assessed the validity and reliability of their ICD-10 codes in the Swedish National Patient Register (NPR). DESIGN: Retrospective chart review. METHODS: Six hundred individuals with a diagnosis of hypochondriasis or dysmorphophobia (300 each) were randomly selected from the NPR. Their medical files were requested from the corresponding clinics, located anywhere in Sweden. Two independent raters assessed each file according to ICD-10 definitions and Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision and Fifth Edition criteria. Raters also completed the Clinical Global Impression-Severity (CGI-S) and the Global Assessment of Functioning (GAF). PRIMARY OUTCOME MEASURE: Per cent between-rater agreement and positive predictive value (PPV). Intraclass correlation coefficients for the CGI-S and the GAF. RESULTS: Eighty-four hypochondriasis and 122 dysmorphophobia files were received and analysed. The inter-rater agreement rate regarding the presence or absence of a diagnosis was 95.2% for hypochondriasis and 92.6% for dysmorphophobia. Sixty-seven hypochondriasis files (79.8%) and 111 dysmorphophobia files (91.0%) were considered 'true positive' cases (PPV=0.80 and PPV=0.91, respectively). CGI-S scores indicated that symptoms were moderately to markedly severe, while GAF scores suggested moderate impairment for hypochondriasis cases and moderate to serious impairment for dysmorphophobia cases. CGI-S and GAF inter-rater agreement were good for hypochondriasis and moderate for dysmorphophobia. CONCLUSIONS: The Swedish ICD-10 codes for hypochondriasis and dysmorphophobia are sufficiently valid and reliable for register-based studies. The results of such studies should be interpreted in the context of a possible over-representation of severe and highly impaired cases in the register, particularly for dysmorphophobia.

Background: Psychological recidivism-reducing interventions with serious, young violent offenders in residential care have unsatisfactory effects. We tested if a complementary individual cognitive behavioral therapy (iCBT) intervention focusing problem-solving, cognitive self-control, and relapse prevention reduces criminal recidivism beyond usual institutional care encompassing interventions such as social skills training and prosocial modeling (treatment-as-usual; TAU). Method: We consecutively approached 115 eligible serious, male violent crime offenders in five residential treatment homes run by the Swedish National Board of Institutional Care. Eighty-one (70%) 16 to 21-year-old youth at medium-high violent recidivism risk were included and randomized to an individualized 15 to 20-session CBT intervention plus TAU (n = 38) or to TAU-only (n = 43), 4-6 months before release to the community. Participants were assessed pre- and post-treatment, at 12 months (self-reported aggressive behavior, reconvictions) and 24 months (reconvictions) after release. Intent-to-treat analyses were applied. Results: The violent reconviction rate was slightly higher for iCBT+TAU vs. TAU-only youth at 12 months (34 vs. 23%, d = 0.30, 95% CI: -0.24 to 0.84) and 24 months following release (50 vs. 40%, d = 0.23, 95% CI: -0.25 to 0.72), but neither of these differences were significant. Cox regression modeling also suggested non-significantly, negligibly to slightly more violent, and any criminal recidivism in iCBT+TAU vs. TAU-only youth during the entire follow-up. Further, we found no significant between-group differences in conduct problems, aggression, and antisocial cognitions, although both iCBT+TAU and TAU-only participants reported small to large within-group reductions across outcome measures at post-treatment. Finally, the 12-month follow-up suggested marginally more DSM-5 Conduct Disorder (CD) symptoms of "aggression to people and animals" in iCBT+TAU vs. TAU-only youth (d = 0.10, 95% CI: -0.40 to 0.60) although this difference was not significant. Conclusion: We found no additive effect of individual CBT beyond group-based TAU in residential psychological treatment for serious, young male violent offenders. Limited sample size and substantial treatment dropout reduced the robustness of intent-to-treat effect estimates. We discuss the possible impact of treatment dose and integrity, participant retention, and TAU quality.
RESUMO
Background: Social anxiety disorder (SAD) has its typical onset in childhood and adolescence. Maladaptive processing of social information may contribute to the etiology and maintenance of SAD. During face perception, individuals execute a succession of visual fixations known as a scanpath which facilitates information processing. Atypically long scanpaths have been reported in adults with SAD, but no data exists from pediatric samples. SAD has also been linked to atypical arousal during face perception. Both metrics were examined in one of the largest eye-tracking studies of pediatric SAD to date. Methods: Participants were children and adolescents with SAD (n = 61) and healthy controls (n = 39) with a mean age of 14 years (range 10-17) who completed an emotion recognition task. The visual scanpath and pupil dilation (an indirect index of arousal) were examined using eye tracking. Results: Scanpaths of youth with SAD were shorter, less distributed, and consisted of a smaller number of fixations than those of healthy controls. These findings were supported by both frequentist and Bayesian statistics. Higher pupil dilation was also observed in the SAD group, but despite a statistically significant group difference, this result was not supported by the Bayesian analysis. Conclusions: The results were contrary to findings from adult studies, but similar to what has been reported in neurodevelopmental conditions associated with social interaction impairments. Restricted scanpaths may disrupt holistic representation of faces known to favor adaptive social understanding.
RESUMO
Importance: Social anxiety disorder (SAD) is a prevalent childhood-onset disorder associated with lifelong adversity and high costs for the individual and society at large. Cognitive behavioral therapy (CBT) is an established evidence-based treatment for SAD, but its availability is limited. Objective: To assess the efficacy and cost-effectiveness of therapist-guided internet-delivered cognitive behavioral therapy (ICBT) for SAD in youths vs an active comparator, internet-delivered supportive therapy (ISUPPORT). Design, Setting, and Participants: This single-masked, superiority randomized clinical trial enrolled participants at a clinical research unit integrated within the child and adolescent mental health services in Stockholm, Sweden, from September 1, 2017, to October 31, 2018. The final participant reached the 3-month follow-up (primary end point) in May 2019. Children and adolescents 10 to 17 years of age with a principal diagnosis of SAD and their parents were included in the study. Interventions: ICBT and ISUPPORT, both including 10 online modules, 5 separate parental modules, and 3 video call sessions with a therapist. Main Outcomes and Measures: The Clinician Severity Rating (CSR), derived from the Anxiety Disorder Interview Schedule, rated by masked assessors 3 months after the end of treatment. The CSR ranges from 0 to 8, with scores of 4 or higher indicating caseness. Secondary outcomes included masked assessor-rated diagnostic status of SAD and global functioning, child- and parent-reported social anxiety and depressive symptoms, and health-related costs. Results: Of the 307 youths assessed for eligibility, 103 were randomized to 10 weeks of therapist-guided ICBT (n = 51) or therapist-guided ISUPPORT (n = 52) for SAD. The sample consisted of 103 youths (mean [SD] age, 14.1 [2.1] years; 79 [77%] female). Internet-delivered cognitive behavioral therapy was significantly more efficacious than ISUPPORT in reducing the severity of SAD symptoms. Mean (SD) CSR scores for ICBT at baseline and at the 3-month follow-up were 5.06 (0.95) and 3.96 (1.46), respectively, compared with 4.94 (0.94) and 4.48 (1.30) for ISUPPORT. There was a significant between-group effect size of d = 0.67 (95% CI, 0.21-1.12) at the 3-month follow-up. Similarly, all of the secondary outcome measures demonstrated significant differences with small to large effect sizes, except for child-rated quality of life (nonsignificant). The cost-effectiveness analyses indicated cost savings associated with ICBT compared with ISUPPORT, with the main drivers of the savings being lower medication costs (z = 2.38, P = .02) and increased school productivity (z = 1.99, P = .047) in the ICBT group. There was 1 suicide attempt in the ISUPPORT group; no other serious adverse events occurred in either group. Conclusions and Relevance: In this randomized clinical trial, internet-delivered cognitive behavioral therapy was an efficacious and cost-effective intervention for children and adolescents with SAD. Implementation in clinical practice could markedly increase the availability of effective interventions for SAD. Trial Registration: ClinicalTrials.gov Identifier: NCT03247075.

BACKGROUND: Social anxiety disorder (SAD) is linked to atypical attention to other's eyes. Empirical literature about this phenomenon in childhood and adolescence is scarce. Previous studies in adults have suggested that SAD may be characterized by either rapid avoidance of eye contact, or by impaired shifting of attention away from eyes once eye contact has been established. SAD has also been linked to quick orienting towards eyes, indicating vigilant monitoring of perceived threat. METHODS: In the largest eye-tracking study of youth with SAD to date, 10 to 17 year-olds with SAD (n = 88) and healthy controls (n = 62) were primed to look at either the eyes or the mouth of human faces. The latency and likelihood of a first gaze shift from, or to the eyes, was measured. RESULTS: Individuals with SAD were slower to shift their gaze away from the eye region of faces than controls, but did not differ in orienting toward eyes. LIMITATIONS: Participants were assessed once after the onset of SAD symptoms, meaning that the longitudinal predictive value of delayed gaze shifts from others' eyes could not be examined. CONCLUSIONS: Youth with SAD may be impaired in shifting attention from other's eyes. This could contribute to the experience of eye contact as aversive, and may be a maintaining factor of childhood SAD.

Internet-delivered cognitive behaviour therapy (ICBT) is emerging as a powerful tool to fill the gap between demand and availability of evidence-based treatment for paediatric anxiety disorders. However, it is still unclear how to best implement it in routine clinical care. 123 children (8-12 years) with anxiety disorders underwent a 12-week ICBT programme with limited therapist support. Participants were assessed 3- and 12-month post-ICBT (3MFU and 12MFU, respectively). Non-remitters who still fulfilled diagnostic criteria for their principal anxiety disorder at 3MFU were offered additional manualised "face-to-face" (F2F) CBT. The aim of the study was to emulate a stepped-care model of health care delivery, where the long-term treatment gains of ICBT as well as the potential benefit of proving addition treatment to non-remitters of ICBT were evaluated. Remitters of ICBT (n = 73) continued to improve throughout the study period (pre-ICBT to 12MFU; Cohen's d = 2.42). At 12MFU, 89% (n = 65) were free from their principal anxiety disorder. Of all the participants classed as non-remitters at 3MFU (n = 37), 48.6% (n = 18) accepted the offer to receive additional F2F CBT. These participants also improved with a large effect from pre-ICBT to 12MFU (Cohen's d = 2.27), with the largest effect occurring during F2F CBT. At 12MFU, 83% (n = 15) were free from their principal anxiety disorders. The majority of non-remitters declining additional F2F CBT (63.2%; n = 12) did so due to already receiving treatment at their local CAMHS, prior to 3MFU. The effects of ICBT for anxiety disorders are durable at least up to 1 year after the end of treatment. Patients who fail to fully benefit from ICBT improved further with additional F2F sessions at our clinic, suggesting that it may be feasible to implement ICBT within a stepped-care model of health care delivery.

Introduction: Individuals tend to explore the left side of a face first and for a longer time in comparison to the right side. This left visual field (LVF) bias is suggested to reflect right hemispheric dominance for face processing. Social anxiety disorder (SAD) is associated with maladaptive interpretations of facial expressions, but it is not known whether this is linked to an atypical LVF bias. Previous studies have reported a reduced LVF bias in autism, a condition overlapping with SAD. This pre-registered study examined the LVF bias in adolescents with SAD. Methods: Eye-tracking was used to investigate the ratio of first fixations to the left on upright and inverted face stimuli in 26 adolescents (13-17 years) with SAD and 23 healthy controls primed to look either between the eyes or at the mouth. Results: The SAD group showed a smaller LVF bias and an atypical face inversion effect when primed to look at the eyes. Autistic traits predicted a smaller LVF bias, independently of social anxiety level. Conclusions: Results suggest that SAD is associated with impaired processing of faces at an early stage of visual scanning. The findings contribute to a better understanding of SAD and its overlap with autism.

BACKGROUND: Population-based administrative registers are often used for research purposes. However, their potential usefulness depends on the validity of the registered information. This study assessed the validity of the recorded codes for social anxiety disorder (SAD), also known as social phobia, in the Swedish National Patient Register (NPR). METHODS: The personal identification numbers of 300 randomly selected individuals with a diagnosis of SAD recorded in the NPR were obtained from the Swedish National Board of Health and Welfare. The medical files of these individuals were then requested from clinics nationally. A total of 117 files were received and two independent raters reviewed each file to assess the presence or absence of SAD, according to the definition of the International Classification of Diseases, Tenth Edition (ICD-10) and the diagnostic criteria of the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR). When disagreements between the two raters were found, a third rater reviewed the file to establish a best estimate diagnosis. Positive predictive values (PPV) and agreement between the two initial raters (using Cohen's kappa) were calculated. Additionally, raters completed the Clinical Global Impression - Severity (CGI-S) and the Global Assessment of Functioning (GAF) rating scales for each file. Inter-rater agreement for the CGI-S and the GAF was assessed using intraclass correlation coefficients (ICC). RESULTS: After exclusion of files not containing sufficient information, 95 files were included in the analyses. Of these, 77 files (81.05%) were considered to be 'true positive' cases (PPV = 0.81, 95% confidence interval = 0.72-0.88). Inter-rater agreement regarding the presence or absence of SAD was substantial (κ = 0.72). CGI-S and GAF scores indicated that patients were in the moderate range of severity and functional impairment. Inter-rater agreement for the CGI-S and the GAF was moderate to good (ICC = 0.72 and ICC = 0.82, respectively). CONCLUSIONS: The ICD-10 codes for SAD in the Swedish NPR are generally valid and reliable, but we recommend sensitivity analyses in future register-based studies to minimise the impact of potential diagnostic misclassification. Most patients were moderately severe and impaired, suggesting that results from register-based studies of SAD may be generalizable.

BACKGROUND: One in twenty adolescents experience excessive worry and evidence-based psychological therapies are not sufficiently widespread to reach most of those affected. In this multiple baseline evaluation, we assess the feasibility and preliminary efficacy of a scalable, online cognitive-behavioral intervention for adolescents with excessive worry (BIP worry). METHODS: Thirteen adolescents (age 13-17) with excessive worry underwent the 10-week online BIP worry intervention. The treatment also included an online intervention for parents. Completion rates, treatment satisfaction, and adverse events were measures of feasibility. Clinical outcomes included worry severity, symptoms of other anxiety and depression, and general functioning. To control for time and spontaneous fluctuations in symptoms, adolescents were randomized to a 2-, 6-, or 10-week baseline phase prior to treatment. A short measure of worry severity was administered weekly during the baseline and treatment phases. Outcomes were assessed before the baseline-phase, at pre-treatment, post-treatment, and at 1- and 3-month follow-ups. RESULTS: Twelve of 13 included adolescents, together with their parents, participated in BIP worry, with a mean completion rate of 9.8 of the 10 treatment modules. Adolescents reported an average of 4.4 exposures per week as homework during treatment. High levels of treatment adherence, credibility, and satisfaction, and no serious adverse events were reported. Therapists averaged 21 min per week communicating with each family. Linear mixed effects models indicated significant improvements in worry, anxiety, and general functioning from pre- to post-treatment, with these gains maintained at 1- and 3-months follow-up. Reductions in worry severity during treatment were significantly larger than during the baseline phase. The results from the multiple baseline evaluation suggested an association between the introduction of the BIP worry intervention and subsequent symptom change for some but not all adolescents. CONCLUSIONS: BIP worry is a feasible and potentially effective treatment. As the treatment is scalable and involves limited therapist contact, it represents a low-cost method for treating adolescents with excessive worry and anxiety. Further investigation under randomized controlled trial (RCT) conditions is warranted.
RESUMO
Telomere attrition is a hallmark of cellular aging and shorter telomeres have been reported in mood and anxiety disorders. Telomere shortening is counteracted by the enzyme telomerase and cellular protection is also provided by the antioxidant enzyme glutathione peroxidase (GPx). Here, telomerase, GPx, and telomeres were investigated in 46 social anxiety disorder (SAD) patients in a within-subject design with repeated measures before and after cognitive behavioral therapy. Treatment outcome was assessed by the Liebowitz Social Anxiety Scale (self-report), administered three times before treatment to control for time and regression artifacts, and posttreatment. Venipunctures were performed twice before treatment, separated by 9 weeks, and once posttreatment. Telomerase activity and telomere length were measured in peripheral blood mononuclear cells and GPx activity in plasma. All patients contributed with complete data. Results showed that social anxiety symptom severity was significantly reduced from pretreatment to posttreatment (Cohen's d = 1.46). There were no significant alterations in telomeres or cellular protection markers before treatment onset. Telomere length and telomerase activity did not change significantly after treatment, but an increase in telomerase over treatment was associated with reduced social anxiety. Also, lower pretreatment telomerase activity predicted subsequent symptom improvement. GPx activity increased significantly during treatment, and increases were significantly associated with symptom improvement. The relationships between symptom improvement and putative protective enzymes remained significant also after controlling for body mass index, sex, duration of SAD, smoking, concurrent psychotropic medication, and the proportion of lymphocytes to monocytes. Thus, indices of cellular protection may be involved in the therapeutic mechanisms of psychological treatment for anxiety.

Social anxiety disorder (SAD) is a psychiatric condition that often onsets in childhood. Cognitive models underline the role of attention in the maintenance of SAD, but studies on youth populations are few, particularly those using eye tracking to measure attention. Cognitive behavioral therapy (CBT) for SAD includes interventions targeting attention, like exposure to eye contact, but the link between CBT and attention bias is largely unexplored. This study investigated attention bias in youth with SAD and the association with outcome from CBT. Latency to attend to pictures of faces with different emotions (vigilance) and latency to disengage from social stimuli (avoidance) was examined in N = 25 adolescents (aged 13-17) with SAD in relation to treatment outcome. Vigilance was operationalized as the time it took to relocate the gaze from a central position to a peripherally appearing social stimulus. The latency to disengage from a centrally located social stimulus, when a non-social stimulus appeared in the periphery, was used as a proxy for avoidance. Attention characteristics in the SAD group were compared to non-anxious (NA) controls (N = 22). Visual attention was measured using eye tracking. Participants in both the SAD and NA groups were vigilant towards angry faces, compared to neutral and happy faces. Similarly, both groups disengaged attention faster from angry faces. Adolescents with SAD who disengaged faster from social stimuli had less social anxiety after CBT. The results indicate that anxious youth display a vigilant-avoidant attention pattern to threat. However, partly inconsistent with previous research, the same pattern was observed in the NA group.

BACKGROUND: Patient adherence is defined as the extent to which a patient complies with medical or health advice. At present, there is a lack of reliable and valid measures specifically designed to measure adherence to internet-delivered behavioral interventions. OBJECTIVE: The objective of this study was to develop and psychometrically evaluate a novel measure of adherence to guided internet-delivered behavioral interventions. METHODS: In collaboration with experienced clinicians and researchers in the field, a 5-item, clinician-rated internet intervention Patient Adherence Scale (iiPAS) was developed. The initial scale was tested in a sample of children and adolescents (N=50) participating in internet-delivered cognitive behavioral therapy (ICBT) studies. A revised version of the iiPAS was then administered to a larger sample of children and adolescents (N=148) with various behavioral problems participating in ICBT trials. The scale was evaluated according to a classical test theory framework. RESULTS: The iiPAS demonstrated excellent internal consistency. Factor analyses revealed one underlying factor, explaining about 80% of the variance, suggesting that the scale captures a homogeneous adherence construct. The iiPAS was strongly associated with objective measures of patient activity in ICBT (number of logins, number of written characters, and completed modules). Furthermore, mid- and posttreatment ratings of the iiPAS were significantly correlated with treatment outcomes. By contrast, objective measures of patient activity in the Web-based platform did not correlate with treatment outcomes. CONCLUSIONS: The iiPAS could be a useful tool to measure adherence in a broad range of internet-delivered behavioral interventions.

Atypical attention to potential social threats, such as emotional faces, may be one of the core mechanisms underlying social anxiety disorder (SAD). Pupil dilation is an index of locus coreuleus-noradrenergic activity, and closely linked to attention. In the present study, pupil dilation was studied in adolescents with SAD (N = 26; 22 Female) before the onset of a 12-week cognitive behavioral treatment, and in healthy controls (N = 23). Stimuli were faces with angry or happy emotional expressions. Contrary to our hypothesis, the SAD group did not show hyper-responsiveness to angry compared to happy faces. Instead, an atypical time course of the pupil dilation response was found, resulting in an attenuated response during late time stages. Larger pupil dilation amplitude to happy faces before treatment was related to worse treatment response. These results contribute significantly to our understanding of the mechanisms underlying adolescent SAD.

BACKGROUND & AIMS: Scalable and effective treatments are needed for children with functional abdominal pain disorders (FAPDs). We performed a randomized controlled trial of the efficacy and cost effectiveness of cognitive behavioral therapy delivered online (Internet-CBT) compared with usual therapy. METHODS: We studied children (age, 8-12 y) diagnosed with FAPDs, based on the Rome IV criteria, in Sweden from September 2016 through April 2017. The patients were assigned randomly to groups that received 10 weeks of therapist-guided, internet-delivered cognitive behavioral therapy (Internet-CBT, n = 46) or treatment as usual (treatments within the health care and school systems, including medications and visits to doctors and other health care professionals; n = 44). The primary outcome was global child-rated gastrointestinal symptom severity assessed using the Pediatric Quality of Life Gastrointestinal Symptom scale. All outcomes were collected from September 2016 through January 2018. Secondary outcomes included quality of life, gastrointestinal-specific anxiety, avoidance behaviors, and parental responses to children's symptoms. Societal costs and costs for health care consumption were collected during the treatment. RESULTS: Children who received Internet-CBT had a significantly larger improvement in gastrointestinal symptom severity with a medium effect size (Cohen's d = 0.46; 95% CI, 0.05-0.88; number needed to treat, 3.8) compared with children who received the treatment as usual. The children's quality of life, gastrointestinal-specific anxiety, avoidance behaviors, and parental responses to children's symptoms also improved significantly in the Internet-CBT group compared with the treatment as usual group. The effects of Internet-CBT persisted through 36 weeks of follow-up evaluation. Children who received Internet-CBT had significantly less health care use than children who received treatment as usual, with an average cost difference of US $137 (P = .011). We calculated a cost savings of US $1050 for every child treated with Internet-CBT compared with treatment as usual. CONCLUSIONS: In a randomized trial of pediatric patients with FAPDs, we found Internet-CBT to be clinically cost effective compared with treatment as usual. Internet-CBT has the potential to increase the availability of treatment for a number of patients and reduce health care costs. ClinicalTrials.gov: NCT02873078.
