Evaluation of a template for countering misinformation—Real-world Autism treatment myth debunking

Abstract: Misinformation poses significant challenges to evidence-based practice. In the public health domain specifically, treatment misinformation can lead to opportunity costs or direct harm. Alas, attempts to debunk misinformation have proven sub-optimal, and have even been shown to “backfire”, including increasing misperceptions. Thus, optimized debunking strategies have been developed to more effectively combat misinformation. The aim of this study was to test these strategies in a real-world setting, targeting misinformation about autism interventions. In the context of professional development training, we randomly assigned participants to an “optimized-debunking” or a “treatment-as-usual” training condition and compared support for non-empirically-supported treatments before, after, and six weeks following completion of online training. Results demonstrated greater benefits of optimized debunking immediately after training; thus, the implemented strategies can serve as a general and flexible debunking template. However, the effect was not sustained at follow-up, highlighting the need for further research into strategies for sustained change.

What is ‘Agency’? Perspectives in Science Education Research

Abstract: The contemporary interest in researching student agency in science education reflects concerns about the relevance of schooling and a shift in science education towards understanding learning in science as a complex social activity The purpose of this article is to identify problems confronting the science education community in the development of this new research agenda and to argue that there is a need for research in science education that attends to agency as a social practice Despite increasing interest in student agency in educational research, the term ‘agency’ has lacked explicit operationalisation and, across the varied approaches, such as critical ethnography, ethnographies of communication, discourse analysis and symbolic interactionism, there has been a lack of coherence in its research usage There has also been argument concerning the validity of the use of the term ‘agency’ in science education research This article attempts to structure the variety of definitions of ‘student agency’ in

The nature and extent of child protection involvement among heroin‐using mothers in treatment: High rates of reports, removals at birth and children in care

Abstract: Introduction and Aims A substantial proportion of women in treatment for substance use problems are mothers of dependent children, but only a small number of studies have explored the nature and extent of their child protection involvement with substance-using mothers themselves. Design and Methods A large sample of mothers on the opioid treatment program (OTP) in Sydney, Australia, were interviewed. This paper describes their characteristics, the extent and nature of their involvement with the child protection system, the parenting-related interventions provided and their views of their own parenting. Results The 171 mothers were disadvantaged and marginalised and had 302 children under the age of 16 years, 99 of whom were in out-of-home care. Nearly half the children in care (n = 42) had been removed at the time of their birth, and half (n = 49) had been removed from a mother who was on an OTP at the time. Among the younger children (age 1–2 years), higher proportions had been removed at birth than among the older children. None of the 32 mothers who had a child removed at birth and then gave birth subsequently retained care of their new baby. Women often chose to enter treatment (63.6%) for child-related reasons (35%) and attempted to shield their children from their substance use. Few health services were provided to them outside the availability of OTP. Discussion and Conclusions Entering treatment presents an opportunity for improving outcomes for these women and their children and to reduce future involvement with the child protection system.[Taplin S, Mattick RP.

Reductions in C‐reactive protein in older adults with type 2 diabetes are related to improvements in body composition following a randomized controlled trial of resistance training

Abstract: Reductions in skeletal muscle mass and increased adiposity are key elements in the aging process and in the pathophysiology of several chronic diseases. Systemic low grade inflammation associated with obesity has been shown to accelerate the age-related decline in skeletal muscle. The aim of this investigation was to determine the effects of 12 months of progressive resistance training (PRT) on systemic inflammation, and whether reductions in systemic inflammation were associated with changes in body composition. We hypothesized that reductions in systemic inflammation following 12 months of PRT in older adults with type 2 diabetes would be associated with reductions in adiposity and increases in skeletal muscle mass. Participants (n = 103) were randomized to receive either PRT or sham-exercise, 3 days a week for 12 months. C-reactive protein (CRP) was used to assess systemic inflammation. Skeletal muscle mass and total fat mass were determined using bioelectrical impedance. Twelve months of PRT tended to reduce CRP compared to sham exercise (β = −0.25, p = 0.087). Using linear mixed-effects models, the hypothesized relationships between body composition adaptations and CRP changes were significantly stronger for skeletal muscle mass (p = 0.04) and tended to be stronger for total fat mass (p = 0.07) following PRT when compared to sham-exercise. Using univariate regression models, stratified by group allocation, reductions in CRP were associated with increases in skeletal muscle mass (p = 0.01) and reductions in total fat mass (p = 0.02) in the PRT group, but not in the sham-exercise group (p = 0.87 and p = 0.32, respectively). We have shown for the first time that reductions in systemic inflammation in older adults with type 2 diabetes following PRT were associated with increases in skeletal muscle mass. Furthermore, reductions in CRP were associated with reductions in adiposity, but only when associated with PRT. Lifestyle interventions aimed at reducing systemic inflammation in older adults with type 2 diabetes should therefore incorporate anabolic exercise such as PRT to optimize the anti-inflammatory benefits of favorable body composition adaptations.
