Response to Leaf et al., 2021

In this commentary, we respond to a recent article published by Leaf and colleagues (2021), entitled “Concerns About ABA-Based Intervention: An Evaluation and Recommendations”. In their article, the authors attempt to address concerns raised by autistic people about ABA-based interventions. We argue that they only superficially engage with these important issues, and fall short of supporting neurodiversity, despite their intention to do so. We discuss issues related to biased claims of effectiveness of ABA, the potential for ABA-based interventions to cause harm, the reliance on past human rights abuses to justify current potential for harm, a lack of empirical support related to intervention intensity recommended by ABA provider groups, and the rigidity of procedures used to achieve therapist-determined goals.

Behavioural interventions for CVD risk reduction for blue-collar workers: a systematic review

ObjectivesIndividuals working in blue-collar occupations experience high rates of cardiovascular disease (CVD). The purpose of this systematic review is to describe the characteristics and efficacy of behavioural interventions that have targeted CVD risk factors in this high-risk group.MethodsFollowing Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, we searched seven databases to find interventions focused on changing the following: blood pressure, cholesterol, diet, physical activity, smoking or weight. Eligible studies tested a behavioural intervention (not exclusively policy, environmental, or pharmaceutical), in individuals working in blue-collar occupations using a randomised study design. Study quality was evaluated using the National Heart, Lung, and Blood Institute’s study quality assessment tool.Results22 studies evaluating 31 interventions were included: 11 were rated as ‘good’ or ‘fair’ quality. Intervention intensity ranged from a single contact via a mailed letter to studies that included individual-level contacts at multiple time points between staff and participants. Studies that included at least some individual contact generally yielded the greatest effects. Interventions had the greatest observed effects on self-report changes in diet, regardless of intervention intensity. Four of the five higher quality studies that explicitly tailored the intervention to the occupational group were successful at reducing at least one risk factor.ConclusionsInterventions that used individual contact and tailored the intervention to the occupational setting yielded the greatest effects on CVD risk-factor reduction in individuals working in blue-collar occupations. Generally, studies were low quality but showed promising effects for reaching this high-risk population. Future work should incorporate these promising findings in higher quality studies.PROSPERO registration numberCRD42019136183.

Adjusting Intervention Intensity to Support Students With Autism Spectrum Disorder

Special education and related professionals often understand the importance of adhering to intervention procedures (i.e., fidelity), but may be less familiar with concepts of intervention intensity. In some cases, professionals may correctly apply an intervention, but with insufficient intensity. This can result in an intervention failing to produce the expected benefit, which can add to student frustration, lost resources, and teacher burnout. Students with autism spectrum disorder (ASD) often benefit from intensive intervention that contains high rates of opportunities to respond. This article provides an overview of a practical guide for adjusting intervention intensity for students with ASD through a three-step process that includes identifying when to adjust intensity along with three ways to adjust intervention intensity. Additional considerations are included for analyzing student responses for data-based decision-making.

The effect of early autism intervention on parental sense of efficacy in a randomized trial depends on the initial level of parent stress

This study examined whether style or intensity of child-focused intervention had a secondary effect on parental sense of efficacy and whether these effects varied by baseline level of parent stress. We randomized 87 children with autism, age 13–30 months, into one of four conditions: 15 versus 25 intervention hours crossed with 12 months of Early Intensive Behavioral Intervention versus Early Start Denver Model. Baseline parent stress was the putative moderator. Parent sense of efficacy, collected at baseline and the end of treatment, was the dependent variable. Analyses used generalized linear mixed model with full information maximum likelihood estimation. We tested main effects and interactions involving time, treatment intensity and style, and baseline parent stress to test moderation effects. Changes in parent efficacy across 12 months were related to intervention intensity but not style; this effect was moderated by level of parent stress at baseline. Parents with higher stress at the beginning of a 1-year, home-based, comprehensive intervention program had a higher sense of parenting efficacy if their child received lower intensity intervention; parents with lower stress at baseline had a higher sense of efficacy if their child received higher intensity intervention. Lay abstract This is a study of the secondary effects of interventions for young children with autism on their parents. Specifically, we were interested in the impact on parent’s sense of efficacy, or how confident and competent a parent feels about themselves as a parent. We tested three ideas: (1) that the style of the intervention, whether it was more or less structured and whether the parent had a more or less formal role, would impact a parent’s sense of efficacy; (2) that the intensity of the intervention, how many hours per week the intervention was delivered, would impact parental efficacy; and (3) that the parent’s level of stress prior to intervention would impact how intensity and style effected efficacy. We randomly assigned 87 children with autism, age 13–30 months, into one of four conditions: 15 versus 25 intervention hours crossed with two different styles of intervention. We used statistical tests to examine these ideas. We found that parental efficacy was related to intervention intensity but not style. Parents with higher stress at the beginning of a 1-year, home-based, comprehensive intervention program had a higher sense of parenting efficacy if their child received lower intensity intervention; parents with lower stress at baseline had a higher sense of efficacy if their child received higher intensity intervention. If a parent can emerge from the process of diagnosis and early intervention with an increased sense that they can make a difference in their child’s life (i.e. increased sense of efficacy), it may set the stage for meeting the long-term demands of parenting a child with autism.

EFFECT OF EXERCISE IN WATER ON THE MUSCULOSKELETAL PAIN IN PREGNANT WOMEN: A RANDOMIZED CONTROLLED TRIAL

Background: Musculoskeletal disorders have been a major cause of disability in pregnant women. The aim of this study is to determine the effect of exercise in an aquatic environment on the musculoskeletal pain among pregnant women. Material and methods: This randomized clinical trial was conducted on 54 pregnant women aged 20–35 years. The subjects were divided into the intervention group and control groups. Women who were in 20 to 26 weeks of gestation were included in the study. The intervention was Water Exercise in Pregnancy program conducted from week 20 to week 34. The control group received standard prenatal care. Musculoskeletal complications were assessed using the Nordic questionnaires at the baseline and, 4th and 8th week of pregnancy. The intensity of pain was assessed using a visual analog scale in the two groups. Data were analyzed using descriptive and inferential statistics via the SPSS v.16. The lsmeans package was used to examine comparisons. Results: Results of the study showed that level of discomfort and musculoskeletal complications in the intervention group was significantly reduced during the 4th and 8th week of the study compared to the control group ([Formula: see text]). After the intervention, intensity of musculoskeletal pain in the intervention group showed a significant decrease compared to the control group ([Formula: see text]). Conclusion: Exercise in water during pregnancy can be effective to reduce musculoskeletal complications. Aquatic exercises should be developed in the exercise program for pregnant women with musculoskeletal pain.

Exploring the active ingredients of workplace physical and psychological wellbeing programs: a systematic review

Previous reviews have established that workplace wellbeing initiatives are effective at promoting wellbeing, but less is known about which intervention characteristics or “active ingredients” underpin this effectiveness (i.e., behavior change techniques [BCTs]). This review aims to illuminate the connections between the types of BCTs and the level of intervention intensity with intervention effectiveness. A systematic search for peer-reviewed studies evaluating a workplace wellbeing initiative was undertaken across five databases: Medline, Scopus, PsycInfo, and CINAHL (Ovid Emcare). Eligible studies included those that evaluated the effect of a workplace wellbeing initiative on participants’ physical wellbeing (e.g., physical activity and quality of life) and psychological wellbeing (e.g., mental health and stress), were published between 2009 and September 2019, and utilized a comparator (e.g., control group or prepost change). Studies were screened in independent duplicate to minimize bias. Effect sizes were calculated. Following removal of duplicates, 1,541 studies were identified and screened for eligibility. Of these, 23 studies reporting 28 comparisons were deemed to meet eligibility criteria. Just over 50% of these studies reported evidence of either a strong or moderate effect across a physical and a psychological outcome, providing a positive indication that workplace wellbeing programs can promote physical and psychological wellbeing in workers. Interventions tended to employ multiple BCTs (mean range 8.1–9.4), however, no discernible patterns between the types or numbers of BCTs employed and intervention effectiveness was found. Further experimental work is required that compares and contrasts workplace wellbeing initiatives to enable a better understanding of how to develop and implement highly effective programs.

A Comparison of Intervention Intensity and Service Delivery Models With School-Age Children With Speech Sound Disorders in a School Setting

Purpose This study examined intervention intensity and service delivery with school-age children with mild or mild–moderate speech sound disorders. The commonly used business-as-usual (BAU) service delivery model and a shorter, more frequent, individual model (experimental [EXP]) were compared. Method A between-subjects group design was selected. In BAU, 11 children received group sessions, 2 times per week, 30 min per session for 6 weeks. In EXP, 11 children received individual session, 3 times per week, 5 min per session for 6 weeks. Group differences on measures of dose (i.e., therapeutic input and production trials) and cumulative treatment intensity were examined. The extent to which children, across both conditions, demonstrated gains in speech sound accuracy and the extent to which gains differed between BAU and EXP were examined. Results There was a significant group difference on dose. Children in BAU received more therapeutic input and production trials than children in EXP. Cumulative treatment intensity was not statistically different between groups when dose was calculated as therapeutic input or production trials. Results from both conditions indicated statistically significant differences on measures of speech sound accuracy with large effect sizes. No group differences on gains were noted. Conclusions Dose calculated as therapeutic input and production trials plays an important role in understanding the impact of cumulative intervention intensity. Children with mild or mild–moderate speech sound disorders may benefit more from a shorter, frequent, individual service delivery model than a BAU model.
