The deployment,training and teacher relationships of teaching assistants supporting pupils with autistic spectrum disorders (ASD) in mainstream secondary schools

Growing numbers of pupils with autistic spectrum disorders (ASD) are attending mainstream schools, and increasing numbers of additional staff are being deployed to support them. Recent research has cast doubt on the effectiveness of this support, by highlighting issues relating to deployment and training, and to relationships with class teachers. This study, conducted by Wendy Symes, who is a Research Associate at the University of Manchester, and Neil Humphrey, who is Professor of Education in the same university, interviewed 15 teaching assistants supporting pupils with ASD in four mainstream secondary schools in the north‐west of England to explore these issues. Analysis yielded several key findings. The majority of teaching assistants worked with just one pupil at a time and worked in a variety of lessons. Their role primarily involved helping pupils to stay focused and follow instructions. Many teaching assistants had no experience of ASD prior to starting their job. The amount of training received varied, but all felt that generic training about ASD was not helpful. A lack of time for joint planning with teachers was raised as a key concern. These findings are discussed in relation to the growing literature on inclusive education for pupils with ASD.     

Becoming Fathers: Initial Exploration of a Support Program for New Fathers

Emerging fathers experience a variety of stressors, including identity and role transitions, changes in their relationships, and challenges in developing caregiving skills. Increasing expectations for father involvement in childcare are emphasizing the importance of the father role, but social supports for new fathers remain scarce. Nineteen expectant and new fathers participated in a pilot 5-week group intervention aimed at improving stress coping and involvement attitudes using a combination of mindfulness practices and skill-building for parenting and partner communication. We administered surveys pre- and postintervention to assess efficacy in the areas of stress, depressive symptoms, father involvement attitudes, and mindfulness. Within-participant differences were compared across participants as well as examining individual reliable change. Results indicated initial reductions in stress and depressive symptoms and increases in the mindfulness constructs of nonjudgment and nonreactivity. No significant changes were found in father involvement attitudes. Perinatal intervention specific to fathers holds promise as an underexplored avenue for supporting families across the transition to parenthood.     

Adult mental health outcomes of child sexual abuse survivors born at extremely low birth weight

The high prevalence of child sexual abuse (CSA) is concerning, particularly as survivors are at increased risk for multiple adverse outcomes, including poor mental health across the lifespan. Children born at an extremely low birth weight (ELBW; <1000 g) and who experience CSA may be a group that is especially vulnerable to psychopathology later in life. However, no research has considered the mental health risks associated with being born at ELBW and experiencing CSA. In this study, we investigated the mental health of 179 ELBW survivors and 145 matched normal birth weight (NBW; >2500 g) participants at ages 22–26 and 29–36. At age 22–26, CSA was associated with increased odds of clinically significant internalizing (OR = 7.32, 95% CI: 2.31–23.23) and externalizing (OR = 4.65, 95% CI: 1.11–19.51) problems among ELBW participants exposed to CSA compared to those who did not, though confidence intervals were wide. At age 29–36, CSA was linked to increased odds of any current (OR = 3.43, 95% CI: 1.08–10.87) and lifetime (OR = 7.09, 95% CI: 2.00–25.03) non-substance use psychiatric disorders, however, this did not hold after adjustment for covariates. Statistically significant differences in mental health outcomes were not observed in NBW participants exposed to CSA compared to NBW participants who were not exposed. Survivors of significant perinatal adversity who are also exposed to CSA may be at higher risk for psychopathology through the fourth decade of life.     

Comparison of three web-scale discovery services for health sciences research

Objective

The purpose of this study was to investigate the relative effectiveness of three web-scale discovery (WSD) tools in answering health sciences search queries.

Methods

Simple keyword searches, based on topics from six health sciences disciplines, were run at multiple real-world implementations of EBSCO Discovery Service (EDS), Ex Libris''s Primo, and ProQuest''s Summon. Each WSD tool was evaluated in its ability to retrieve relevant results and in its coverage of MEDLINE content.

Results

All WSD tools returned between 50%–60% relevant results. Primo returned a higher number of duplicate results than the other 2 WSD products. Summon results were more relevant when search terms were automatically mapped to controlled vocabulary. EDS indexed the largest number of MEDLINE citations, followed closely by Summon. Additionally, keyword searches in all 3 WSD tools retrieved relevant material that was not found with precision (Medical Subject Headings) searches in MEDLINE.

Conclusions

None of the 3 WSD products studied was overwhelmingly more effective in returning relevant results. While difficult to place the figure of 50%–60% relevance in context, it implies a strong likelihood that the average user would be able to find satisfactory sources on the first page of search results using a rudimentary keyword search. The discovery of additional relevant material beyond that retrieved from MEDLINE indicates WSD tools'' value as a supplement to traditional resources for health sciences researchers.

Adverse experiences in early childhood and their longitudinal impact on later behavioral problems of children living in poverty

BackgroundAdverse childhood experiences (ACEs) are an identified risk factor for the social and emotional development of children. What is less known is the long-term effects of ACEs when poverty and ACEs coincide.ObjectiveUsing longitudinal cohort-panel data, we examined whether exposure to ACEs by the age of three among poor children would longitudinally result in behavioral problems at ages three, five, nine, and 15, after controlling for mothers’ socioeconomic status and their children’s characteristics.Participants and settingWe used a subsample of 2750 children and their parents living in urban poverty from the Fragile Families and Child Wellbeing study.MethodsLogistic regression modeling was used to obtain adjusted odds ratios of ACE categories predicting behavioral problems after accounting for family socioeconomic position.ResultsOur findings indicate that experiencing ACEs in early childhood was significantly associated with later behavioral outcomes from childhood to adolescence. Exposure to multiple ACEs before the age of three was significantly associated with the top-risk behavior group at age five; the odd ratios were 2.0 (CI = 1.3–3.1) and 2.9 (CI = 1.8–4.6) for two ACEs and three or more ACEs, respectively. At both ages nine and 15, children experiencing two or more ACEs had 1.9 to 3.2 times higher odds to demonstrate more the top 10th percentile of behavioral problems. Among covariates, mothers’ race and education, and children’s gender and temperament were identified as significant factors to determine behavior problems.ConclusionsThe findings support policies and programs for families with children who have experienced economic disadvantages and early childhood adversity.     

A mediational model linking perceptions of security,alexithymia and behavior problems of sexually abused children

BackgroundPerceptions of security toward parents are related with internalized and externalized problems among victims of child sexual abuse (CSA). Alexithymia, which is difficulty in identifying and expressing feelings, is associated with the quality of parent-child relationships (Oskis et al., 2013) and behavior problems in children (Di Trani et al., 2013).ObjectiveThe current study tested the mediational role of alexithymia in the relationship between perceptions of security toward parents and behavior problems among CSA victims.Participants and methodUsing a short-term multi-informant prospective design, 263 victims of CSA aged 6–12 years completed the Kerns Security Scale (Kerns, Klepac, & Cole, 1996), which evaluates perceived attachment security to mothers and fathers. Parents completed the Child Behavior Checklist (Achenbach & Rescorla, 2001) at Time 1 to provide baseline scores of behavior problems and again four months later. At Time 2, parents also assessed the children’s alexithymia using the Children’s Alexithymia Measure (Way et al., 2010).ResultsPerceptions of security were both associated with alexithymia, as well as with internalizing and externalizing problems (p < .05). A mediational model showed that perception of security toward fathers outweighed the mother-child relationship in predicting children’s alexithymia. Path analysis revealed that the father-child relationship predicted decreased behavioral problems at Time 2 through a lower level of alexithymia. The model explained 46.9% of internalizing problems and 56.1% of externalizing problems (p < .05).ConclusionsThe findings support the relevance of alexithymia as an intervention target for CSA victims and underscore the importance of the father-child relationship.
