Sub-groups of emotion dysregulation in youth with nonsuicidal self-injury: latent profile analysis of a randomized controlled trial.

Psychological treatments targeting emotion dysregulation in adolescents reduce nonsuicidal self-injury (NSSI) but predicting treatment outcome remains difficult. Identifying sub-groups based on repeated measurements of emotion dysregulation pre-treatment may guide personalized treatment recommendations. We used data from a recent trial evaluating internet-delivered emotion regulation therapy for adolescents with NSSI (n = 138). Latent profile analysis was used to identify sub-groups based on pre-treatment responses on the 16-item version of the Difficulties in Emotion Regulation Scale. The primary outcome was self-rated NSSI frequency during treatment, and secondary outcome was the proportion of participants with no NSSI 1-month post-treatment. Three sub-groups of emotion dysregulation were identified: low variability and low mean (Group 1), low variability and high mean (Group 2), and high variability and low mean (Group 3). Sub-groups did not differ in NSSI frequency during treatment (Group 2 IRR = 1.06 [95% CI 0.49-2.29], p = .88; Group 3 IRR = 1.22 [95% CI 0.31-4.76], p = .77). However, more participants in Group 1 compared to Group 2 abstained from NSSI at 1-month post-treatment (OR = 3.63 [95% CI 1.16-11.33], p = 0.01). Latent profile analysis identified sub-groups predictive of NSSI absence post-treatment, demonstrating clinical utility.

Improved readability in written neurodevelopmental reports by five writing rules.

The purpose of a neuropsychological assessment is to describe a child's difficulties and strengths to enable treatments and contextual adjustments. Typically, the assessment is summarized in the form of a written clinical report. However, such texts have been criticized for being too difficult for parents and teachers to read and comprehend. The purpose of this pre-registered and randomized controlled study was to evaluate five writing rules to improve readability and accessibility in clinical reports: to structure the text with functional domains, exemplify cognitive tasks with examples from daily life, use examples from the daily life of the child, avoid jargon, and to write shorter sentences. We created two separate reports based on the same assessment information of a hypothetical child: one "standard" report, and one where the five writing rules were applied. One hundred teacher students at a teacher education program were randomized to read one of the reports, and then rated readability and answered a comprehension quiz. Results showed that the five writing rules led to improved ratings of readability, and helped readers recall more information immediately afterward. Effects were medium to large. Future studies need to investigate whether the findings generalize to parents and other potential readers. Additionally, future work should address how psychologists can be taught to improve their writing through writing guidelines. Clinical trial registration: https://aspredicted.org/ac96p.pdf.

Perceived causal symptom network of adolescent mental health issues.

Adolescent mental health is difficult to capture in categories such as depression or specific anxiety disorders. An alternative is to approach psychiatric symptoms as causal networks, potentially revealing feedback loops that maintain a pathological state. One approach to creating such networks, implemented in the PECAN methodology, is to ask adolescents about their perceptions of the causes to their symptoms. For this purpose, a transdiagnostic item list was created, and adolescents who screened positive for depression (N = 55) completed twice in two weeks a survey quantifying perceptions of causality between their mental health problems. A network that was averaged across all participants was reliable and revealed three strong feedback loops: a first loop running through stress, insomnia, fatigue, procrastination, and back to stress; a second loop between stress and overthinking; and a third loop between stress and procrastination. Although all adolescents in the study screened positive for depression, symptoms of depression were not particularly central to the network. Instead, the most central symptoms were procrastination and overthinking. The average test-retest reliability for individual networks was low, limiting clinical application. In conclusion, PECAN was found to be reliable and useful when creating a group-level network of adolescent mental health problems. While informative at a group level, the method should be improved before it can be used to inform treatment at the individual level.

TRAS: Validity and sensitivity of a language assessment tool for children with ASD.

Interventions for preschool children with autism typically require professionals and parents to identify which social and language skills the individual child shows deficits in. Many assessment tools aimed at identifying such deficits exist, but they often require extensive training to use. The present study investigated the potential usefulness for said assessment purposes of the Norwegian assessment tool, TRAS - "Tidig Registrering Av Språkutveckling" (i.e. Nordic acronym for assessment of early language development), which can be used by preschool teachers without any specific training. Participants were 54 children with ASD, aged 2-5 years, enrolled in a behavioral intervention program. Participants were scored using TRAS at three time points during treatment to investigate TRAS' sensitivity for detecting change. Only participants who had TRAS scores registered at all three time points were used for this analysis (n = 27). At intake, children were also scored using the Vineland Adaptive Behavior Scales, the results of which was then compared to TRAS scores. Results showed that TRAS scores increased significantly across time points, indicating that the tool is sensitive to treatment effects. TRAS scores also correlated significantly with Vineland communication subscale (n = 50), indicating that the measure can be used to measure language abilities in children with ASD. We conclude that TRAS is a potential alternative to more comprehensive language assessment tools for children with ASD.

A novel approach for constructing personalized networks from longitudinal perceived causal relations.

Personalized networks of psychological symptoms aim to advance therapy by identifying treatment targets for specific patients. Statistical relations in such networks can be estimated from intensive longitudinal data, but their causal interpretation is limited by strong statistical assumptions. An alternative is to create networks from patient perceptions, which comes with other limitations such as retrospective bias. We introduce the Longitudinal Perceived Causal Problem Networks (L-PECAN) approach to address both these concerns. 20 participants screening positive for depression completed 4 weeks day of brief daily assessments of perceived symptom interactions. Quality criteria of this new method are introduced, answering questions such as "Which symptoms should be included in networks?", "How many datapoints need to be collected to achieve stable networks?", and "Does the network change over time?". Accordingly, about 40% of respondents achieved stable networks and only few respondents exhibited network structure that changed during the assessment period. The method was time-efficient (on average 7.4 min per day), and well received. Overall, L-PECAN addresses several of the prevailing issues found in statistical networks and therefore provides a clinically meaningful method for personalization.

Perceived Causal Problem Networks: Reliability, Central Problems, and Clinical Utility for Depression.

Personalized case conceptualization is often regarded as a prerequisite for treatment success in psychotherapy for patients with comorbidity. This article presents Perceived Causal Networks, a novel method in which patients rate perceived causal relations among behavioral and emotional problems. First, 231 respondents screening positive for depression completed an online Perceived Causal Networks questionnaire. Median completion time (including repeat items to assess immediate test-retest reliability) was 22.7 minutes, and centrality measures showed excellent immediate test-retest reliability. Networks were highly idiosyncratic, but worrying and ruminating were the most central items for a third of respondents. Second, 50 psychotherapists rated the clinical utility of Perceived Causal Networks visualizations. Ninety-six percent rated the networks as clinically useful, and the information in the individual visualizations was judged to contain 47% of the information typically collected during a psychotherapy assessment phase. Future studies should individualize networks further and evaluate the validity of perceived causal relations.

Adapting the preschool environment to the needs of children on the autism spectrum in Sweden: A quasi-experimental study.

BACKGROUND: Children on the autism spectrum may receive Early Intensive Behavioural Intervention (EIBI) in Sweden to support development by providing learning opportunities. However, research suggests a need to improve the quality of their learning environment. AIM: This pre-registered study (#NCT03634761) aimed to evaluate the Swedish Autism Program Environment Rating Scale (APERS-P-SE) as a means to promote the quality of the pre-school learning environment for children on the autism spectrum, along with outcomes for these children, and their pre-school staff. MATERIAL AND METHODS: In a quasi-experimental study, pre-school staff (n = 35) conducted either EIBI supported by in-service training and on-site coaching based on APERS-P-SE assessment (at k = 9 preschools) or EIBI only (k = 8), during an 8-months period. RESULTS: The quality of the immediate learning environment (primary outcome) increased significantly in the EIBI/APERS-P-SE preschools. However, changes in child and pre-school staff measures were not significant. CONCLUSIONS AND SIGNIFICANCE: In-service training and on-site coaching based on APERS-P-SE assessments can increase the quality of the learning environment in Swedish pre-school. Studies of longer duration and larger sample size are required to determine if using the APERS-P-SE can also achieve desired behavioural change for children-, and impact pre-school staff applying EIBI.

Treatment Gains from Early and Intensive Behavioral Intervention (EIBI) are Maintained 10 Years Later.

This study reports outcome in adolescents with autism who in their childhood received Early and Intensive Behavioral Intervention (EIBI). Nineteen children (16 boys) who had received two years of EIBI starting at a mean age of 2-years-and-11-months were followed up, on average, 12 years later. Results showed the participants significantly increased their cognitive and adaptive standard scores during the two years of EIBI, and that these gains were maintained at follow-up, 10 years after the EIBI had ended. Participants also showed a significant reduction in autism symptoms between intake and follow-up. At follow-up, none of the participants had received any additional psychiatric diagnoses, and none were taking any psychotropic medication. Results indicate that treatment gains achieved in EIBI are maintained into adolescence.

Children with Autism show Atypical Preference for Non-social Stimuli.

The present investigation describes three studies testing the hypothesis that children with Autism Spectrum Disorder (ASD) show an atypical preference for non-social stimuli. Preference for non-social and social stimuli was assessed using applications on a portable tablet computer. Twenty-eight children with ASD were matched on developmental age with the chronological age of 41 typically developing (TD) children. The non-social stimuli consisted of six different films of abstract moving geometric patterns. Social stimuli were six different films of the face of young adults (Study 1 and 3) or six films of different dogs' faces (Study 2). When given a choice between the non-social and social stimuli, children with ASD preferred the non-social stimuli. When the human faces were replaced with dogs' faces the participants with ASD continued to prefer the non-social stimuli. A high reinforcement value of non-social stimuli was also demonstrated when the non-social stimuli were presented alone, suggesting the preference for the non-social stimuli was not simply an avoidance of social stimuli. Whenever an infant prefers non-social stimuli over social stimuli, non-typical development in social communication and social interests may result, together with the development of high levels and frequently occurring stereotyped and repetitive behavior. These behaviors define Autism.

Cross-Cultural Content Validity of the Autism Program Environment Rating Scale in Sweden.

Increasing rates of autism spectrum disorder (ASD) and younger age at diagnosis pose a challenge to preschool intervention systems. In Sweden, most young autistic children receive intervention service in community-based preschool programs, but no tool is yet available to assess the quality of the preschool learning environment. This study adapted the Autism Program Environment Rating Scale Preschool/Elementary to Swedish community context (APERS-P-SE). Following translation and a multistep modification process, independent experts rated the content validity of the adaptation. Findings indicate high cross-cultural validity of the adapted APERS-P-SE. The cultural adaption process of the APERS-P-SE highlights similarities and differences between the American and Swedish preschool systems and their impact on early ASD intervention.

Allegiance and knowledge levels of professionals working with early intensive behavioural intervention in autism.

AIM: Early intensive behavioural intervention (EIBI) for children with autism spectrum disorder (ASD) is often delivered using a community model. Behaviour modification experts train and supervise non-experts (e.g. preschool personnel) to teach children according to applied behaviour analysis principles in their natural environment. Several factors predict EIBI outcomes in ASD, for example, knowledge of EIBI and EIBI allegiance among trainers. The aim of the present study was to survey levels of knowledge about and allegiance towards EIBI. METHODS: Formal knowledge of EIBI and EIBI allegiance was surveyed in supervised preschool staff conducting EIBI (n = 33), preschool staff not involved in EIBI (n = 26), behaviour modification experts (n = 60), school staff (n = 25) and parents of children with ASD (n = 150) [N = 294]. A 27-item (15 knowledge and 12 allegiance questions) online questionnaire was collected. RESULTS: Supervised preschool staff conducting EIBI had more knowledge than preschool staff not using EIBI, but they were not more allegiant. Compared with behaviour modification experts, the supervised EIBI preschool staff group showed markedly less knowledge and allegiance. CONCLUSIONS: Findings indicate potential for improvement regarding formal knowledge levels of preschool staff delivering EIBI to children with ASD in real-world settings. In addition, fostering EIBI allegiance might be prioritized when teaching EIBI among non-experts. Broadly increased EIBI knowledge levels among all preschool teachers should be achieved by adding behaviour modification techniques to common university curricula in preschool education. Allegiance of preschool personnel might be accomplished by EIBI supervisors meeting skepticism in practice with conveyance of evidence-based principles and discussions of ethical issues.

Narrowing the gap: effects of intervention on developmental trajectories in autism.

Although still a matter of some debate, there is a growing body of research supporting Early and Intensive Behavioral Intervention as the intervention of choice for children with autism. Learning rate is an alternative to change in standard scores as an outcome measure in studies of early intervention. Learning rates can be displayed graphically as developmental trajectories, which are easy to understand and avoid some of the counter-intuitive properties of changes in standard scores. The data used in this analysis were from 453 children with autism, previously described by Eldevik et al. Children receiving Early and Intensive Behavioral Intervention exhibited significantly steeper developmental trajectories than children in the control group, in both intelligence and adaptive behaviors. However, there was a considerable variability in individual learning rates within the group receiving Early and Intensive Behavioral Intervention. This variability could partly be explained by the intensity of the treatment, partly by children's intake intelligence quotient age-equivalents. Age at intake did not co-vary with learning rate.

Interest level in 2-year-olds with autism spectrum disorder predicts rate of verbal, nonverbal, and adaptive skill acquisition.

Recent studies have suggested that skill acquisition rates for children with autism spectrum disorders receiving early interventions can be predicted by child motivation. We examined whether level of interest during an Autism Diagnostic Observation Schedule assessment at 2 years predicts subsequent rates of verbal, nonverbal, and adaptive skill acquisition to the age of 3 years. A total of 70 toddlers with autism spectrum disorder, mean age of 21.9 months, were scored using Interest Level Scoring for Autism, quantifying toddlers' interest in toys, social routines, and activities that could serve as reinforcers in an intervention. Adaptive level and mental age were measured concurrently (Time 1) and again after a mean of 16.3 months of treatment (Time 2). Interest Level Scoring for Autism score, Autism Diagnostic Observation Schedule score, adaptive age equivalent, verbal and nonverbal mental age, and intensity of intervention were entered into regression models to predict rates of skill acquisition. Interest level at Time 1 predicted subsequent acquisition rate of adaptive skills (R(2) = 0.36) and verbal mental age (R(2) = 0.30), above and beyond the effects of Time 1 verbal and nonverbal mental ages and Autism Diagnostic Observation Schedule scores. Interest level at Time 1 also contributed (R(2) = 0.30), with treatment intensity, to variance in development of nonverbal mental age.

Grammatical constructions in typical developing children: effects of explicit reinforcement, automatic reinforcement and parity.

This study replicated and extended Wright (2006) and Whitehurst, Ironsmith, and Goldfein (1974) by examining whether preschool aged children would increase their use of passive grammatical voice rather than using the more age-appropriate active grammatical construction when the former was modeled by an adult. Results showed that 5 of the 6 participants began using the passive voice after this verbal behavior had been modeled. For 3 of the participants, this change was large. The change occurred even though the adult model explicitly rewarded the participant with praise and stickers for using the active voice, while providing no praise or stickers for using the passive form that was modeled. For 1 participant, the modeling procedure had no effect on use of the passive voice. These results indicate a strong automatic reinforcement effect of achieving parity with the grammatical structures used by adults, compared to the effects of explicit reinforcement by the adult. This might help to explain why children acquire grammatical structures prevalent in their language community apparently without explicit instruction.

Sensory abnormalities in autism. A brief report.

Sensory abnormalities were assessed in a population-based group of 208 20-54-month-old children, diagnosed with autism spectrum disorder (ASD) and referred to a specialized habilitation centre for early intervention. The children were subgrouped based upon degree of autistic symptoms and cognitive level by a research team at the centre. Parents were interviewed systematically about any abnormal sensory reactions in the child. In the whole group, pain and hearing were the most commonly affected modalities. Children in the most typical autism subgroup (nuclear autism with no learning disability) had the highest number of affected modalities. The children who were classified in an "autistic features" subgroup had the lowest number of affected modalities. There were no group differences in number of affected sensory modalities between groups of different cognitive levels or level of expressive speech. The findings provide support for the notion that sensory abnormality is very common in young children with autism. This symptom has been proposed for inclusion among the diagnostic criteria for ASD in the upcoming DSM-V.
