Could linguistic and cognitive factors, degree of autistic traits and sex predict speech disfluencies in autistic young adults and controls?

This study aimed to evaluate the effect of linguistic complexity and individual background variables (i.e. linguistic and cognitive abilities, degree of autistic traits, and sex) on speech disfluencies in autistic young adults and controls. Thirty-two 19- to 33-year-old autistic adults and 35 controls participated in this study. The frequency of disfluencies and stuttering severity were evaluated based on a narrative speech task. Linguistic complexity was assessed by evaluating the syntactic structures of the narratives. Cognitive and linguistic abilities were assessed using the General Ability Index (GAI), Verbal Comprehension Index (VCI) and Perceptual Reasoning Index (PRI) from the Wechsler Adult Intelligence Scale IV. Autistic traits were measured using the Autism Spectrum Quotient (AQ). Multiple-linear regression analyses (syntactic complexity, GAI, AQ, sex, and group status as predictors) showed that (a) syntactic complexity predicted total and stuttering-like disfluencies and stuttering severity, (b) GAI predicted typical disfluencies, and (c) sex predicted total, typical, and stuttering-like disfluencies. Additional correlation analyses revealed negative association between PRI and disfluencies in the control group but not in the autistic group. No connection was found between AQ and disfluencies. It seems that while some connections between disfluencies and individual cognitive features were found, some of the possible contributing factors for greater speech disfluency might differ between autistic and typical speakers.

Factor analysis of the autism spectrum screening questionnaire in a population-based child sample.

PURPOSE: The aim of this study was to investigate several possible factor structures of the Autism Spectrum Screening Questionnaire (ASSQ). MATERIALS AND METHODS: We used the 27-item screening tool for school-aged children in a general population of 8-year-old children (n = 3,538) and compared the occurring solutions to previously published factor models. RESULTS: A one-factor solution and a four-factor solution were identified in Exploratory Factor Analysis (EFA) and confirmed with Confirmatory Factor Analysis (CFA), while two-, three-, five- and six-factor solutions were rejected. In CFA, our four-factor solution showed the best goodness-of-fit indexes when compared with factor models previously presented by Posserud et al. and Ehlers et al. CONCLUSIONS: The results indicate a strong underlying connection between all ASSQ items which is elicited by the one-factor solution. Although as a screening tool, ASSQ is functioning with the unifactorial solution, the four factors can help to identify certain clusters of autism spectrum traits.

A Comprehensive Analysis of Speech Disfluencies in Autistic Young Adults and Control Young Adults: Group Differences in Typical, Stuttering-Like, and Atypical Disfluencies.

PURPOSE: The purpose of this study was to examine the nature of speech disfluencies in autistic young adults and controls by using a wide-range disfluency classification of typical disfluencies (TD; i.e., filled pauses, revisions, abandoned utterances, and multisyllable word and phrase repetitions), stuttering-like disfluencies (SLD; i.e., sound and syllable repetitions, monosyllable word repetitions, prolongations, blocks, and broken words), and atypical disfluencies (AD; i.e., word-final prolongations and repetitions and atypical insertions). METHOD: Thirty-two autistic young adults and 35 controls completed a narrative telling task based on socially complex events. Frequencies of total disfluencies, TD, SLD, AD and stuttering severity were compared between groups. RESULTS: The overall frequency of disfluencies was significantly higher in the autistic group and significant between-group differences were found for all disfluency categories. The autistic group produced significantly more revisions, filled pauses, and abandoned utterances, and each subtype of SLD and AD than the control group. In total, approximately every fourth autistic participants scored at least a very mild severity of stuttering, and every fifth produced more than three SLD per 100 syllables. CONCLUSIONS: Disfluent speech can be challenging for effective communication. This study revealed that the speech of autistic young adults was highly more disfluent than that of the controls. The findings provide information on speech disfluency characteristics in autistic young adults and highlight the importance of evaluating speech disfluency with a wide-range disfluency classification in autistic persons in order to understand their role in overall communication. The results of this study offer tools for SLPs to evaluate and understand the nature of disfluencies in autistic persons.

Non-linguistic comprehension, social inference and empathizing skills in autistic young adults, young adults with autistic traits and control young adults: Group differences and interrelatedness of skills.

BACKGROUND: Despite increasing knowledge of social communication skills of autistic peole, the interrelatedness of different skills such as non-linguistic comprehension, social inference and empathizing skills is not much known about. A better understanding of the complex interplay between different domains of social communication helps us to develop assessment protocols for individuals with social communication difficulties. AIMS: To compare the performances of autistic young adults, young adults with autistic traits identified in childhood and control young adults in social communication tasks measuring non-linguistic comprehension, social inference and empathizing skills. In addition, to examine associations between the different social communication measures. METHODS & PROCEDURES: Autistic young adults (n = 34), young adults with autistic traits (n = 19) and control young adults (n = 36) completed the extra- and paralinguistic scales of the Assessment Battery for Communication (ABaCo), the Faux Pas Recognition Test, Social-Pragmatic Questions (SoPra) and the Empathy Quotient (EQ). OUTCOMES & RESULTS: Group differences were found in the performance in the ABaCo, SoPra and EQ scores. Compared with the control young adults, autistic young adults scored lower. The performance of the young adults in the autistic traits group fell in between the other two groups. There were no group differences in the Faux Pas Recognition Test. The variability within the groups was large in all measurements. In the control group, there was a significant correlation between EQ and SoPra scores and between the Faux Pas and SoPra scores. In the autistic group, a significant correlation was found between Faux Pas and SoPra scores. Also, other patterns were observed but these were not statistically significant. CONCLUSIONS & IMPLICATIONS: The young adults with autistic traits fell in between the control and autistic young adults, highlighting the presence of the continuum in the terms of features of social communication. The results support other current research that suggests that theory of mind and other social communication skills may not be universally or widely impaired in all autistic individuals without cognitive deficits. Although all tasks examined social communication skills, only a small number of significant correlations were found between test scores. This highlights that clinical conclusions about a person's social communication should be based on the outcomes of different types of methods measuring different aspects of social communication. It is clear that the interrelatedness of different social communication skills needs further research. WHAT THIS PAPER ADDS: What is already known on this subject For successful communication, the ability to infer others' emotions, intentions and mental states is crucial. Autistic people have difficulty with many aspects of social communication. However, the associations between different aspects of social communication need to be better understood. What this paper adds to existing knowledge The unique contribution of this study is to compare the performance of autistic people not only with that of a control group but also with people with childhood autistic traits. This provides an understanding of the interrelatedness of different social communication skills in people with varying degrees of autistic traits. This study used four assessment methods focusing on three different social communication elements (non-linguistic comprehension, social inference and empathizing skills). These elements have complex relationships to one another, some being closely overlapping, some more distally related and some reflect more complex multifactorial elements. This study shows that although groups differ from each other in most of the assessments, the performance of different groups overlapped showing that many autistic young adults can perform well in non-linguistic and social inference tasks in structured assessment contexts. What are the potential or actual clinical implications of this work? Our findings suggest that in the assessment of social communication, self-reports and clinical assessments can be used effectively together. They can complement each other, pointing out the strengths and weaknesses of a person, leading to more personalized therapeutic interventions.

Autistic adults and adults with sub-clinical autistic traits differ from non-autistic adults in social-pragmatic inferencing and narrative discourse.

LAY ABSTRACT: Previous social-pragmatic and narrative research involving autistic individuals has mostly focused on children. Little is known about how autistic adults and adults who have autistic traits but do not have a diagnosis of an autism spectrum disorder (ASD) interpret complex social situations and tell narratives about these situations. We asked 32 autistic young adults, 18 adults with autistic traits but no ASD diagnosis, and 34 non-autistic young adults to watch socially complex situations and freely tell narratives about what they thought was occurring in each situation. These narratives were analysed for how the participants had interpreted the situations and for the type of narratives they produced. We found that the groups had both similarities and differences. Regarding the differences, we found that the autistic adults and adults with autistic traits interpreted the situations differently from the non-autistic adults. The autistic adults found different aspects of the situations relevant, had different foci and placed greater importance on details than the non-autistic adults. The autistic adults and adults with autistic traits also differed from the non-autistic adults by having more detail- and event-focused narratives whereas the non-autistic adults were more likely to base their narratives on their own broad interpretations of the situations. Perceptual processing styles appeared to play a bigger role in interpreting the situations for the autistic adults and adults with autistic traits than the non-autistic adults. Our findings suggest that autistic adults and adults with autistic traits focus on different aspects in their social world than non-autistic adults.

Effect of Topical Antibiotics on Duration of Acute Infective Conjunctivitis in Children: A Randomized Clinical Trial and a Systematic Review and Meta-analysis.

Importance: Although topical antibiotics are often prescribed for treating acute infective conjunctivitis in children, their efficacy is uncertain. Objective: To assess the efficacy of topical antibiotic therapy for acute infective conjunctivitis. Design, Setting, and Participants: A randomized clinical trial was conducted in primary health care in Oulu, Finland, from October 15, 2014, to February 7, 2020. Children aged 6 months to 7 years with acute infective conjunctivitis were eligible for enrollment. The participants were followed up for 14 days. A subsequent meta-analysis included the present trial and 3 previous randomized clinical trials enrolling pediatric patients aged 1 month to 18 years with acute infective conjunctivitis. Interventions: Participants in the present randomized clinical trial were randomized to moxifloxacin eye drops, placebo eye drops, or no intervention. Main Outcomes and Measures: The primary outcome in the present randomized clinical trial was time to clinical cure (in days); in the meta-analysis, the primary outcome was the proportion of participants with conjunctival symptoms on days 3 to 6. Results: The randomized clinical trial included 88 participants (46 [52%] girls), of whom 30 were randomized to moxifloxacin eye drops (mean [SD] age, 2.8 [1.6] years), 27 to placebo eye drops (mean [SD], age 3.0 [1.3] years), and 31 to no intervention (mean [SD] age, 3.2 [1.8] years). The time to clinical cure was significantly shorter in the moxifloxacin eye drop group than in the no intervention group (3.8 vs 5.7 days; difference, -1.9 days; 95% CI, -3.7 to -0.1 days; P = .04), while in the survival analysis both moxifloxacin and placebo eye drops significantly shortened the time to clinical cure relative to no intervention. In the meta-analysis, a total of 584 children were randomized (300 to topical antibiotics and 284 to a placebo), and the use of topical antibiotics was associated with a significant reduction in the proportion of children who had symptoms of conjunctivitis on days 3 to 6 compared with placebo eye drops (odds ratio, 0.59; 95% CI, 0.39 to 0.91). Conclusions and Relevance: In this randomized clinical trial and systematic review and meta-analysis, topical antibiotics were associated with significantly shorter durations of conjunctival symptoms in children with acute infective conjunctivitis.

Social-Pragmatic Inferencing, Visual Social Attention and Physiological Reactivity to Complex Social Scenes in Autistic Young Adults.

This study examined social-pragmatic inferencing, visual social attention and physiological reactivity to complex social scenes. Participants were autistic young adults (n = 14) and a control group of young adults (n = 14) without intellectual disability. Results indicate between-group differences in social-pragmatic inferencing, moment-level social attention and heart rate variability (HRV) reactivity. A key finding suggests associations between increased moment-level social attention to facial emotion expressions, better social-pragmatic inferencing and greater HRV suppression in autistic young adults. Supporting previous research, better social-pragmatic inferencing was found associated with less autistic traits.

Co-activation pattern alterations in autism spectrum disorder-A volume-wise hierarchical clustering fMRI study.

INTRODUCTION: There has been a growing effort to characterize the time-varying functional connectivity of resting state (RS) fMRI brain networks (RSNs). Although voxel-wise connectivity studies have examined different sliding window lengths, nonsequential volume-wise approaches have been less common. METHODS: Inspired by earlier co-activation pattern (CAP) studies, we applied hierarchical clustering (HC) to classify the image volumes of the RS-fMRI data on 28 adolescents with autism spectrum disorder (ASD) and their 27 typically developing (TD) controls. We compared the distribution of the ASD and TD groups' volumes in CAPs as well as their voxel-wise means. For simplification purposes, we conducted a group independent component analysis to extract 14 major RSNs. The RSNs' average z-scores enabled us to meaningfully regroup the RSNs and estimate the percentage of voxels within each RSN for which there was a significant group difference. These results were jointly interpreted to find global group-specific patterns. RESULTS: We found similar brain state proportions in 58 CAPs (clustering interval from 2 to 30). However, in many CAPs, the voxel-wise means differed significantly within a matrix of 14 RSNs. The rest-activated default mode-positive and default mode-negative brain state properties vary considerably in both groups over time. This division was seen clearly when the volumes were partitioned into two CAPs and then further examined along the HC dendrogram of the diversifying brain CAPs. The ASD group network activations followed a more heterogeneous distribution and some networks maintained higher baselines; throughout the brain deactivation state, the ASD participants had reduced deactivation in 12/14 networks. During default mode-negative CAPs, the ASD group showed simultaneous visual network and either dorsal attention or default mode network overactivation. CONCLUSION: Nonsequential volume gathering into CAPs and the comparison of voxel-wise signal changes provide a complementary perspective to connectivity and an alternative to sliding window analysis.

Staircase-pattern neonatal line in human deciduous teeth is associated with tooth type.

OBJECTIVE: The staircase (Sc) pattern enamel microstructure is an expression of an impaired ameloblast function. It has been reported to appear in the neonatal line (NNL), the accentuated stria evincing live birth in deciduous tooth enamel. Our objective was to investigate the prevalence of Sc NNL in deciduous tooth types and its possible association with perinatal circumstances. DESIGN: Sc in the NNL of 88 teeth, a collection derived from a long-term, prospectively followed population cohort, was recorded with linear polarised transmitted light and analysed for tooth type, duration and mode of delivery, and pain medication used during labour. RESULTS: Sc prevalence in the NNL differed highly significantly between tooth types (p < 0.0001). An increase in Sc prevalence was significantly associated with an increased ratio of prenatal to total crown enamel (p < 0.001), when buccal and lingual crown walls were analysed separately. No significant association was found between Sc prevalence and duration or mode of delivery or pain-relieving medication (p = 0.57, p = 0.65, p = 0.58, respectively). CONCLUSION: This research indicates that the NNL location within tooth crown enamel has a strong impact on microstructural changes along the NNL. Considering our results of Sc prevalence, deciduous canines, having the least Sc appearance, could be used in studies that aim to investigate factors associated with NNL width. In addition, Sc prevalence variation in first deciduous molars might enable to investigation of physiological stressors strong enough to cause ameloblast impairment, such as Sc.

Adolescent with caries and experienced interaction with dental staff.

BACKGROUND: There is a lack of studies about how adolescents experience the interaction during dental visits. The experienced interaction during dental visits will influence how adolescents take care of their oro-dental health, and how they attend at the dentist's office. AIM: To explore the interaction experiences during dental visits of 18-year-olds with or without a history of caries. DESIGN: The dental health status at age 15 years was used as a predictor of subsequent interaction experiences with the dental staff. The dental health status was assessed by the Decayed Missed Filled Teeth index and interaction experiences by the Patient Dental Staff Interaction Questionnaire. RESULTS: Adolescents with a history of caries experienced the interaction at dental visits significantly more often negatively than adolescents with healthy teeth. The association was significant after adjustment for potential confounding factors (sense of coherence, gender, and duration of maternal basic education). CONCLUSIONS: Understanding, encouraging, and appropriate interaction with adolescents with caries may make patients more positive and receptive for treatment and self-care.

How young adults with autism spectrum disorder watch and interpret pragmatically complex scenes.

The aim of the current study was to investigate subtle characteristics of social perception and interpretation in high-functioning individuals with autism spectrum disorders (ASDs), and to study the relation between watching and interpreting. As a novelty, we used an approach that combined moment-by-moment eye tracking and verbal assessment. Sixteen young adults with ASD and 16 neurotypical control participants watched a video depicting a complex communication situation while their eye movements were tracked. The participants also completed a verbal task with questions related to the pragmatic content of the video. We compared verbal task scores and eye movements between groups, and assessed correlations between task performance and eye movements. Individuals with ASD had more difficulty than the controls in interpreting the video, and during two short moments there were significant group differences in eye movements. Additionally, we found significant correlations between verbal task scores and moment-level eye movement in the ASD group, but not among the controls. We concluded that participants with ASD had slight difficulties in understanding the pragmatic content of the video stimulus and attending to social cues, and that the connection between pragmatic understanding and eye movements was more pronounced for participants with ASD than for neurotypical participants.

Neuropsychological performance of Finnish and Egyptian children with autism spectrum disorder.

BACKGROUND: Previous studies investigating neuropsychological functioning of children with autism spectrum disorder (ASD) have only analysed certain abilities, such as executive functions or language. While comprehensive assessment of the neuropsychological profile of children with ASD has been the focus of recent research, most of the published evidence originates from single centres. Though studies on differences in neuropsychological features of children with ASD across countries are essential for identifying different phenotypes of ASD, such studies have not been conducted. OBJECTIVE: Our goal was to assess the neuropsychological abilities of children with ASD in northern Finland and Egypt and to examine the effect of age and intelligence quotient (IQ) on these abilities. DESIGN: Selected verbal and non-verbal subtests of the neuropsychological assessment NEPSY were used to examine 88 children with ASD in northern Finland (n=54, age M=11.2, IQ M=117.1) and Egypt (n=34, age M=8.4, IQ M=96.6). RESULTS: Finnish ASD children scored significantly higher than their Egyptian counterparts on the verbal NEPSY subtests Comprehension of Instructions (p<0.001), Comprehension of Sentence Structure (p<0.01), Narrative Memory (p<0.001) and Verbal Fluency (p<0.05) and on the non-verbal NEPSY subtest Design Fluency (p<0.01). Finnish and Egyptian ASD children did not differ on the subtests Memory for Faces, Object Recognition and Object Memory. In addition, we found that age and verbal IQ can have significant influence on neuropsychological performance. CONCLUSIONS: Our results suggest a possible cultural impact on verbal and visuomotor fluency. However, the ability to recognize and memorize objects and the disability to remember faces appear to be typical for ASD and culturally independent.

Oral health-related knowledge, attitudes and habits in relation to perceived oral symptoms among 12-year-old school children.

Objective The aim of the study was to investigate oral health-related knowledge, attitudes and habits and their relationship to perceived oral symptoms among 12-year-olds and differences between boys and girls. Material and methods The study population consisted of children (n = 588) in 15 randomly selected elementary schools in Turku, Finland. Associations between oral health-related habits, knowledge and attitudes with perceived oral symptoms and gender differences were evaluated with χ(2)-test, Mann-Whitney U-test and logistic regression analysis. Results Oral health promoting habits but not knowledge or attitudes associated significantly with absence of oral symptoms. Girls reported a higher percentage of several health promotional habits than boys. Girls reported more frequently gingival bleeding and less frequently dental calculus than boys did. The most common oral symptom was gingival bleeding. Conclusions The present findings suggest some gender-related differences in oral health habits, attitudes, as well as perceived oral symptoms in 12-year-olds. There seems, however, not to be gender differences in relation to knowledge or the association of health habits with perceived oral symptoms. It is important to maintain health promotion at schools and additional efforts should be aimed at translating knowledge into action.

Attention and Working Memory in Adolescents with Autism Spectrum Disorder: A Functional MRI Study.

The present study examined attention and memory load-dependent differences in the brain activation and deactivation patterns between adolescents with autism spectrum disorders (ASDs) and typically developing (TD) controls using functional magnetic resonance imaging. Attentional (0-back) and working memory (WM; 2-back) processing and load differences (0 vs. 2-back) were analysed. WM-related areas activated and default mode network deactivated normally in ASDs as a function of task load. ASDs performed the attentional 0-back task similarly to TD controls but showed increased deactivation in cerebellum and right temporal cortical areas and weaker activation in other cerebellar areas. Increasing task load resulted in multiple responses in ASDs compared to TD and in inadequate modulation of brain activity in right insula, primary somatosensory, motor and auditory cortices. The changes during attentional task may reflect compensatory mechanisms enabling normal behavioral performance. The inadequate memory load-dependent modulation of activity suggests diminished compensatory potential in ASD.

Influence of children's oral health promotion on parents' behaviours, attitudes and knowledge.

Objective The aim was to compare the changes in parents' oral health-related behaviour, knowledge and attitudes in 2001-2003 and 2003-2005, during a 3.4-year-intervention in Pori and in the reference area Rauma, Finland. Materials and methods The study population consisted of parents of children who participated in the oral health promotion programme in Pori (all 5th and 6th graders who started the 2001-2002 school year in the town of Pori, n = 1691) and the parents of same-aged children in a reference town (n = 807). In 2001-2003, the promotion was targeted only to the children in Pori. In 2003-2005, the promotion was targeted also to parents, for example via local mass media. The statistical significances of the differences in parents' self-reported behaviour, knowledge and attitudes, and changes in these, were evaluated using Mann-Whitney U-tests and confidence intervals. Results In 2001-2003, the trend in changing behaviours was in favour of parents in Pori. Mothers in Pori also improved their knowledge and the attitude 'importance of brushing for health and appearance'. In 2003-2005, the trend in changing behaviours was rather similar in both towns, which may be due to diffusion of the oral health intervention to Rauma via the media. Conclusions The results suggest that health promotion targeted to children, which in previous studies has been shown to be successful in improving children's behaviours, also helped their parents in mending their habits.

Dental fear affects adolescent perception of interaction with dental staff.

The main purpose of this study was to explore whether subjective perception of interaction with dental staff is associated with dental fear in a population-based sample of 18-yr-old adolescents (n = 773). The interaction was measured using the Patient Dental Staff Interaction Questionnaire (PDSIQ), validated with exploratory and confirmatory factor analyses, which yielded the factors of 'kind atmosphere and mutual communication', 'roughness', 'insecurity', 'trust and safety', and 'shame and guilt'. Dental fear was measured using the Modified Dental Anxiety Scale (MDAS). Gender and sense of coherence (SOC) were included as potential confounding variables. Adolescents with high dental fear more often perceived their interaction with dental staff negatively and more often felt insecure than others. This difference persisted after adjustment for gender and SOC. In conclusion, adolescents with high dental fear may perceive their interaction with dental staff more positively if the staff succeed in creating a positive, trusting, approving, and supportive atmosphere with kindness, calmness, and patience. The communication and interaction skills of dental staff may play a particularly important role when encountering highly fearful dental patients.

Oral health behavior at age of 11-12 years predicting educational plans at age of 15-16 years.

OBJECTIVE: The aim was to determine if oral health-related behavior at the age of 11-12 years predicts adolescents' educational plans at the age of 15-16 years when adjusting for gender and parents' occupational level. MATERIALS AND METHODS: The study population consisted of all fifth and sixth graders starting in the 2001-2002 school year in Pori, Finland (n = 1691); of these, 1467 returned properly filled questionnaires on behavior (toothbrushing and consumptions of xylitol products, candies, soft drinks and sports drinks) in 2001 and on educational plans in 2005. Parents' occupational levels were reported in 2001 by one of the parents of 1352 of these children. Associations between adolescents' educational plans and their behavior, gender and parents' occupation were evaluated using logistic regression model. RESULTS: Children's oral health-related behavior at age 11-12, gender and parent's occupational level predicted their educational plans at age 15-16. Association between educational plans and behavior, especially cumulative health behavior, remained statistically significant when controlling for gender and parent's occupation: OR = 1.4 for difference of one good habit, and OR = 5.3 for difference of five good habits. CONCLUSIONS: Since difference in oral health-related behavior can be seen already in primary school, even when controlling for parents' occupational level, polarization of adolescents may begin already in primary school stage or even earlier.

Resting state fMRI reveals a default mode dissociation between retrosplenial and medial prefrontal subnetworks in ASD despite motion scrubbing.

In resting state functional magnetic resonance imaging (fMRI) studies of autism spectrum disorders (ASDs) decreased frontal-posterior functional connectivity is a persistent finding. However, the picture of the default mode network (DMN) hypoconnectivity remains incomplete. In addition, the functional connectivity analyses have been shown to be susceptible even to subtle motion. DMN hypoconnectivity in ASD has been specifically called for re-evaluation with stringent motion correction, which we aimed to conduct by so-called scrubbing. A rich set of default mode subnetworks can be obtained with high dimensional group independent component analysis (ICA) which can potentially provide more detailed view of the connectivity alterations. We compared the DMN connectivity in high-functioning adolescents with ASDs to typically developing controls using ICA dual-regression with decompositions from typical to high dimensionality. Dual-regression analysis within DMN subnetworks did not reveal alterations but connectivity between anterior and posterior DMN subnetworks was decreased in ASD. The results were very similar with and without motion scrubbing thus indicating the efficacy of the conventional motion correction methods combined with ICA dual-regression. Specific dissociation between DMN subnetworks was revealed on high ICA dimensionality, where networks centered at the medial prefrontal cortex and retrosplenial cortex showed weakened coupling in adolescents with ASDs compared to typically developing control participants. Generally the results speak for disruption in the anterior-posterior DMN interplay on the network level whereas local functional connectivity in DMN seems relatively unaltered.

Dental fear and sense of coherence among 18-yr-old adolescents in Finland.

The aim was to investigate whether dental fear was associated with the sense of coherence (SOC) among 18-yr-old adolescents (n = 777). Cross-sectional data from a prospective cohort of a random sample of families from Finland and their first-born children were used. Dental fear was measured using the Modified Dental Anxiety Scale and categorized as high dental fear for scores of 19-25 and as no to moderate dental fear for scores of 5-18. Sense of coherence was measured using a 13-item version of Antonovsky's Sense of Coherence Questionnaire, dichotomized as scores 13-63 for weak SOC and as scores of 64-91 for strong SOC. Gender and education were included as background factors in the logistic regression analyses. The prevalence of high dental fear was 8%. Those reporting high dental fear reported more often a weaker SOC than did those with no to moderate dental fear (69% vs. 31%, OR = 2.5, 95% CI = 1.4-4.4), also when adjusted for gender and education (OR = 2.2, 95% CI = 1.2-3.9). According to the theory of salutogenesis, as proposed by Antonovsky, SOC is a resource instrument especially in situations of tension or strain and hence a strong SOC might protect against high dental fear.

Social anxiety in parents of high-functioning children with autism and Asperger syndrome.

We evaluated social anxiety (SA) symptoms in parents of children with autism spectrum disorders (ASDs; N = 131) and community parents (N = 597) using the Social Phobia and Anxiety Inventory (SPAI). SA was significantly more common in ASD than control mothers (15.6 vs. 6.7 %) and more equal between the ASD and control fathers (3.3 vs. 4.8 %). The ASD mothers scored significantly higher than control mothers on all SPAI scales. ASD fathers scored significantly higher than control fathers on the somatic, cognitive, avoidance and agoraphobic symptoms of SA. It is of clinical import to support ASD parents' well-being as their psychiatric features may contribute greatly to their children's emotional development and the well-being of the whole family.
