Getting ‘stuck’, literally and figuratively, is a common experience for autistic people. Literally ‘stuck’ means exhibiting limited response initiation due to immobility with tense muscles and inability to move. Figuratively ‘stuck’ means loneliness, passivity or captivity in activities that do not offer long-term satisfaction. To further conceptualize this complex phenomenon of limited response initiation in autistic individuals, we performed qualitative interviews and focus groups with autistic people and their family members, followed by brainstorm sessions and a Delphi study with input from a larger panel of experts from multiple backgrounds. We aimed to co-create the outline of an integrative approach to support autistic people in moving away from this ‘stuck state’ to more flexible, limber ‘supple states’ in order to live freer, more meaningful, satisfying and peaceful lives. Over time, in interaction with all participants, our shared insight grew. Based on this, we here stipulate a conceptual framework, in which the described ‘stuck state’ at the micro-level of the muscles/behavior of one individual, probably is caused by feeling/being ‘stuck’ or ‘cramped’ at several overarching (i.e., meso and macro) levels. For instance, stuck in relationships with unhealthy dynamics, stuck at home creating short-term calm, trance-like states (e.g., gaming), stuck at an educational level that might fit the individuals’ current social–emotional state rather than their potential cognitive level, stuck in a job that pays the bills but does not feel meaningful, nor contributes to a satisfying life with opportunities for personal development. Stuck in a mental/public health care system where ever ongoing changes in policies hinder sustained support to suit care-needs. Stuck in a regulated societal system making it likely to repeatedly get stuck. Is this phenomenon specific to autism? Formally we have only conducted interviews with this population, but in another smaller, related project we also spoke to people from the general population with careers that are considered successful in the general society. These people actually voiced similar experiences. Therefore, we hypothesize that this numbing state of being or feeling ‘stuck’ may be a prevalent phenomenon that needs to be addressed. In this article, we discuss several types of interventive approaches (i.e., language-based talking therapies, affective experiential expressive therapies, physical therapies and systemic therapies), prevention as well as intervention programs, directed at different primary stakeholders, that can complement and enrich each other in an integrative policy, that leads to tailor-made, personalized trajectories of interdisciplinary support to enable people to live satisfying, meaningful, dignified and peaceful lives.

Based on literature research, focus groups and in-depth interviews, it was found that behavioral problems in adolescents and young adults with autism spectrum disorder were associated with an interrelated complex of factors at the micro, meso and macro level. This complex of factors – as described in detail in this article – gives rise to a process because of which this population cannot optimally participate in society regarding several areas, such as school and work. To prevent such a declining process, a sustainable, multi-sectorial approach is needed. For this purpose, currently as part of the Academic Workplace Autism, inter-disciplinary teams are co-creating a set of complementary, suitable innovations.

In order to shed more light on why referred girls are less likely to be diagnosed with autism spectrum disorder than boys, this study examined whether behavioral characteristics influence the probability of an autism spectrum disorder diagnosis differently in girls versus boys derived from a multicenter sample of consecutively referred children aged 2.5–10 years. Based on information from the short version of the Developmental, Dimensional and Diagnostic Interview and the Autism Diagnostic Observation Schedule, 130 children (106 boys and 24 girls) received a diagnosis of autism spectrum disorder according to Diagnostic and Statistical Manual of Mental Disorders (4th ed., text rev.) criteria and 101 children (61 boys and 40 girls) did not. Higher overall levels of parent-reported repetitive and restricted behavior symptoms were less predictive of an autism spectrum disorder diagnosis in girls than in boys (odds ratio interaction = 0.41, 95% confidence interval = 0.18–0.92, p = 0.03). In contrast, higher overall levels of parent-reported emotional and behavioral problems increased the probability of an autism spectrum disorder diagnosis more in girls than in boys (odds ratio interaction = 2.44, 95% confidence interval = 1.13–5.29, p = 0.02). No differences were found between girls and boys in the prediction of an autism spectrum disorder diagnosis by overall autistic impairment, sensory symptoms, and cognitive functioning. These findings provide insight into possible explanations for the assumed underidentification of autism spectrum disorder in girls in the clinic.

The current study aimed to investigate the Autism Diagnostic Interview-Revised (ADI-R) algorithms for toddlers and young preschoolers (Kim and Lord, J Autism Dev Disord 42(1):82-93, 2012) in a non-US sample from ten sites in nine countries (n = 1,104). The construct validity indicated a good fit of the algorithms. The diagnostic validity was lower, with satisfactorily high specificities but moderate sensitivities. Young children with clinical ASD and lower language ability were largely in the mild-to-moderate or moderate-to-severe concern ranges of the ADI-R, nearly half of the older and phrase speech ASD-group fell into the little-to-no concern range. Although broadly the findings support the toddler algorithms, further work is required to understand why they might have different properties in different samples to further inform research and clinical use.

In order to understand typical and atypical developmental trajectories it is important to assess how strengths or weaknesses in one domain may be affecting performance in other domains. This study examined longitudinal relations between early fine motor functioning, visuospatial cognition, exploration, and language development in preschool children with ASD and children with other developmental delays/disorders. The ASD group included 63 children at T1 (Mage = 27.10 months, SD = 8.71) and 46 children at T2 (Mage = 45.85 months, SD = 7.16). The DD group consisted of 269 children at T1 (Mage = 17.99 months, SD = 5.59), and 121 children at T2 (Mage = 43.51 months, SD = 3.81). A subgroup nested within the total sample was randomly selected and studied in-depth on exploratory behavior. This group consisted of 50 children, 21 children with ASD (Mage = 27.57, SD = 7.09) and 29 children with DD (Mage = 24.03 months, SD = 6.42). Fine motor functioning predicted language in both groups. Fine motor functioning was related to visuospatial cognition in both groups and related to object exploration, spatial exploration, and social orientation during exploration only in the ASD group. Visuospatial cognition and all exploration measures were related to both receptive and expressive language in both groups. The findings are in line with the embodied cognition theory, which suggests that cognition emerges from and is grounded in the bodily interactions of an agent with the environment. This study emphasizes the need for researchers and clinicians to consider cognition as emergent from multiple interacting systems.

In a randomized controlled trial, we evaluated the early intervention program Video-feedback Intervention to promote Positive Parenting adapted to Autism (VIPP-AUTI) with 78 primary caregivers and their child (16–61 months) with Autism Spectrum Disorder. VIPP-AUTI is a brief attachment-based intervention program, focusing on improving parent–child interaction and reducing the child’s individual Autism Spectrum Disorder–related symptomatology in five home visits. VIPP-AUTI, as compared with usual care, demonstrated efficacy in reducing parental intrusiveness. Moreover, parents who received VIPP-AUTI showed increased feelings of self-efficacy in child rearing. No significant group differences were found on other aspects of parent–child interaction or on child play behavior. At 3-months follow-up, intervention effects were found on child-initiated joint attention skills, not mediated by intervention effects on parenting. Implementation of VIPP-AUTI in clinical practice is facilitated by the use of a detailed manual and a relatively brief training of interveners.

A large number of studies have reported on the validity of autism spectrum disorder (ASD) screening procedures. An overall understanding of these studies' findings cannot be based solely on the level of internal validity of each, since screening instruments might perform differently according to certain factors in different settings. Europe has led the field with the development of the first screening tool and first prospective screening study of autism. This paper seeks to provide an overview of ASD screening studies and ongoing programmes across Europe, and identify variables that have influenced the outcomes of such studies. Results show that, to date, over 70,000 children have been screened in Europe using 18 different screening procedures. Differences among findings across studies have enabled us to identify ten factors that may influence screening results. Although it is impossible to draw firm conclusions as to which screening procedure is most effective, this analysis might facilitate the choice of a screening method that best fits a specific scenario, and this, in turn, may eventually improve early ASD detection procedures.

Objective: One of the most powerful medications that have very broad aspects of clinical application are the selective serotonin reuptake inhibitors (SSRI). We use SSRI as a first choice agents in treatment of depression, obsessive-compulsive disorders and some anxiety disordes. Objective: To analyze the outcome of treatment of adolescent depresion with SSRI’s, considering the age group, disorder categories, response to treatment and side effects. Methods: A retrospective epidemiological investigation was conducted by means of medical records for all adolescent treated with sertraline during six months period at the Department of Child and Adolescent Psychiatry in Belgrade. The clinical response to treatment was rated by Beck Depression Inventory and Hamilton Depression Rating Scale. Results: 5 boys and 10 girls (mean age 15.7) were treated with sertraline during the first episode of depression; administred doses were 50–75 mg per day. 86% of patients improved, 10% droped out because of economic reasons, and 4% experienced side affects (nausea, vomiting, headache). Conclusion: Sertraline is potent, safe and effective in the treatment of young people with first episode of depression.

Goal: The goal of this symposium is to identify ‘state-of-the-art’ strategies for the use of antipsychotic medications in the management of children and adolescents with major psychiatric disorders. Learning objectives: 1. Define pediatric populations for whom second-generation antipsychotics are indicated 2. Identify the role of second-generation antipsychotics in the management of major psychiatric disorders in children and adolescents 3. Describe the level of evidence for the effectiveness of second-generation anti-psychotic use in youth 4. Discuss risk-benefit ratios of individual second-generation antipsychotics in pediatric populations 5. Use treatment algorithms and practice guidelines for the safe and effective use of second-generation antipsychotics in children and adolescents Background: Second-generation antipsychotics are increasingly prescribed to children and adolescents targeting a variety of psychotic and non-psychotic disorders. This is mainly due to lower rates of neuromotor side effects compared to conventional antipsychotics. In addition, second generation antipsychotics may also have superior and broader effectiveness than traditional antipsychotics. Content: This symposium will focus on the evaluation of the evidence base for the safety and effectiveness of second generation antipsychotics in the treatment of children and adolescents with major psychiatric disorders. Furthermore, treatment guidelines and algorithms will be presented to help guide clinician’s treatment decisions.
