• Rhotic Generalization Is More Rapid in Biofeedback Than Motor-Based Treatment for Residual Speech Sound Disorder: Secondary Outcomes of a Randomized Controlled Trial

  Journal of Speech Language and Hearing Research · 2026-02-23

  articleOpen access

  PURPOSE: This study examined the effects of visual biofeedback approaches and nonbiofeedback motor-based treatment on generalization outcomes following speech therapy for children with residual speech sound disorders (RSSDs). METHOD: A total of 108 children aged 9-15 years with RSSD affecting American English /ɹ/ were randomly assigned to receive 19 motor-based speech treatment sessions, with or without visual biofeedback (divided into ultrasound or visual-acoustic biofeedback). The treatment included practice designed to implement several motor learning principles, with task difficulty systematically adjusted based on the child's performance. Children's /ɹ/ accuracy on untreated words before and after treatment was rated as correct or incorrect by lay listeners who were blinded to participant characteristics, treatment conditions, and time points. RESULTS: The mixed-effects regression model revealed a statistically significant interaction between treatment type and time point. Specifically, both the biofeedback and nonbiofeedback motor-based treatment groups made progress over time, but the amount of generalization to untreated words was significantly greater in the biofeedback condition than in the motor-based treatment. In a subanalysis comparing biofeedback types, greater generalization was observed following ultrasound biofeedback than visual-acoustic biofeedback, although this effect was strongest at one treatment site. DISCUSSION: This randomized controlled trial found that adding biofeedback to motor-based treatment can increase the rate of accurate production of the American English /ɹ/ in untreated words.

• Methylphenidate Treatment and Risk of Psychotic Disorder

  JAMA Psychiatry · 2026-03-25

  articleOpen access

  Importance: Methylphenidate is the leading pharmacological treatment for attention-deficit/hyperactivity disorder (ADHD) in childhood and adolescence. Individuals with ADHD have a higher risk of psychosis, but the long-term relationship between methylphenidate and risk of developing psychotic disorders is unknown. Objective: To estimate the relationship between methylphenidate treatment and the risk of nonaffective psychosis in children and adolescents diagnosed with ADHD. Design, Setting, and Participants: This cohort study included instrumental variable analysis of data linkage from multiple national Finnish registries for all individuals born from 1987 to 1997 (n = 697 289). These registries were used to identify childhood and adolescent ADHD diagnoses (age <18 years) from 2003 onwards. Data were analyzed from June 2023 to December 2025. Exposure: Cumulative amount of treatment with methylphenidate used in 4 intervention windows: within 1, 2, 3, and 4 years after ADHD diagnosis. Hospital district prescribing propensities (average prescribing within each hospital district, within each intervention window) were used as instruments. Main Outcome and Measures: Diagnosis of nonaffective psychotic disorder (by code from International Statistical Classification of Diseases and Related Health Problems, Tenth Revision) by the end of follow-up (December 31, 2016). Instrumental variable analyses were conducted using 2-stage least squares modeling and the Anderson-Rubin test. Risk differences (RDs) were estimated for each intervention window. Results: Among 3956 individuals diagnosed with ADHD (3181 male [80.4%], 775 female [19.6%]; median [IQR] age, 14.16 [11.78-15.93] years), 2728 (69.0%) received methylphenidate at least once. A total of 222 individuals (5.7%) were diagnosed with nonaffective psychosis by mean (SD) age 22.16 (2.39) years (range, 19.00-29.81 years). There was substantial variation in hospital district prescribing propensity (for example, first-year range, 0.07 to 0.30). Instrumental variable analysis indicated that sustained treatment with methylphenidate (30 mg/d) was not associated with the risk of nonaffective psychosis in the overall ADHD sample (1-year RD, -0.14; 95% CI, -0.85 to 0.42; and 4-year RD, -0.15; 95% CI, -0.49 to 0.11). Secondary analyses indicated a reduced risk of nonaffective psychosis among individuals diagnosed in childhood (age <13 years: 3-year RD, -0.24; 95% CI, -0.45 to -0.03; P = .03; 4-year RD, -0.21; 95% CI, -0.48 to -0.07; P = .02). An insufficiently strong instrument precluded the same secondary analyses in those diagnosed in adolescence. Conclusion and Relevance: This study of national Finnish registry data for individuals with ADHD found no overall relationship between sustained treatment with methylphenidate risk of nonaffective psychosis; in secondary analyses, a potentially protective effect of methylphenidate treatment against later psychosis in children diagnosed with ADHD was found. Further research is needed to evaluate potential effects of treatment in individuals diagnosed in adolescence and adulthood.

• Synthetic Control Misconceptions: Recommendations for Practice

  ArXiv.org · 2026-03-19

  articleOpen access

  To estimate the causal effect of an intervention, researchers need to identify a control group that represents what might have happened to the treatment group in the absence of that intervention. This is challenging without a randomized experiment and further complicated when few units (possibly only one) are treated. Nevertheless, when data are available on units over time, synthetic control (SC) methods provide an opportunity to construct a valid comparison by differentially weighting control units that did not receive the treatment so that their resulting pre-treatment trajectory is similar to that of the treated unit. The hope is that this weighted ``pseudo-counterfactual" can serve as a valid counterfactual in the post-treatment time period. Since its origin twenty years ago, SC has been used over 5,000 times in the literature (Web of Science, December 2025), leading to a proliferation of descriptions of the method and guidance on proper usage that is not always accurate and does not always align with what the original developers appear to have intended. As such, a number of accepted pieces of wisdom have arisen: (1) SC is robust to various implementations; (2) covariates are unnecessary, and (3) pre-treatment prediction error should guide model selection. We describe each in detail and conduct simulations that suggest, both for standard and alternative implementations of SC, that these purported truths are not supported by empirical evidence and thus actually represent misconceptions about best practice. Instead of relying on these misconceptions, we offer practical advice for more cautious implementation and interpretation of results.

• Effectiveness of non-pharmaceutical interventions as implemented in the UK during the COVID-19 pandemic: a rapid review

  Journal of Public Health · 2025-03-04 · 5 citations

  reviewOpen access

  BACKGROUND: Although non-pharmaceutical inventions (NPIs) were used globally to control the spread of COVID-19, their effectiveness remains uncertain. We aimed to assess the evidence on NPIs as implemented in the UK, to allow public health bodies to prepare for future pandemics. METHODS: We used rapid systematic methods (search date: January 2024) to identify, critically appraise and synthesize interventional, observational and modelling studies reporting on NPI effectiveness in the UK. RESULTS: Eighty-five modelling, nine observational and three interventional studies were included. Modelling studies had multiple quality issues; six of the 12 non-modelling studies were high quality. The best available evidence was for test and release strategies for case contacts (moderate certainty), which was suggestive of a protective effect. Although evidence for school-related NPIs and universal lockdown was also suggestive of a protective effect, this evidence was considered low certainty. Evidence certainty for the remaining NPIs was very low or inconclusive. CONCLUSION: The validity and reliability of evidence on the effectiveness of NPIs as implemented in the UK during the COVID-19 pandemic is weak. To improve evidence generation and support decision-making during future pandemics or other public health emergencies, it is essential to build evaluation into the design of public health interventions.

• Who Works Non–Day Shifts? An Investigation of Population and Within-Cohort Trends

  Journal of Occupational and Environmental Medicine · 2025-03-20

  article

  OBJECTIVES: We examined trends in the socioeconomic distribution of work schedules from 1990s to 2010s and how early adulthood disadvantages are associated work schedules over working age. METHODS: In a representative sample of US workers (Midlife in the U.S. Study (MIDUS), N = 3328), we calculated recycled predictions of day, evening, night, and long shift prevalence associated with time period. Logistic regression was used to analyze the association of non-day shifts with age and its variations by early adulthood disadvantage in US baby boomers (National Longitudinal Survey of Youth 79 (NLSY79), N = 10,293). RESULTS: In U.S. workers, between 1990s-2010s, evening shifts increased in adults without college education and night shifts increased in the lowest income quartile. Day shifts decreased in both groups. In US baby boomers, the odds of working non-day shifts decreased with age. However, being Black, not attending college, and poverty were associated with higher odds of non-day shiftwork throughout working age. CONCLUSIONS: Evening and night shifts may have replaced day shifts in socioeconomically disadvantaged populations between 1990s-2010s. Early adulthood disadvantages may have sustained effects on work schedules.

• Rhotic Acquisition Is More Rapid in Biofeedback Than Motor-Based Treatment for Residual Speech Sound Disorder: Primary Outcome of a Randomized Controlled Trial

  Journal of Speech Language and Hearing Research · 2025-09-08 · 1 citations

  article

  PURPOSE: Residual speech sound disorder (RSSD) is a high-prevalence condition that can limit children's academic and social participation, with negative consequences for overall well-being. Previous studies have described visual biofeedback as a promising option for RSSD, but results have been inconclusive due to study design limitations and small sample sizes. METHOD: In a preregistered randomized controlled trial, 108 children aged 9-15 years with RSSD affecting American English /ɹ/ were randomly assigned to receive treatment incorporating visual biofeedback (subdivided into ultrasound and visual-acoustic types) or a comparison condition of motor-based treatment consistent with current best practices in speech therapy. An acoustic measure (the distance between the second and third formants, which is smaller in perceptually accurate /ɹ/) was used to quantify progress in the first three sessions of treatment in participants' assigned condition. The focus on the early stages of treatment was grounded in principles of motor learning: As a type of knowledge of performance feedback, biofeedback is expected to have its greatest impact during initial acquisition of a new speech-motor plan. RESULTS: A linear mixed-effects regression model revealed a statistically significant interaction between treatment type and session: While both groups made progress over time, the rate of progress was significantly faster in the biofeedback condition compared to motor-based treatment. No statistically significant difference was observed between the ultrasound and visual-acoustic types of biofeedback. DISCUSSION: This large-scale randomized controlled trial supports previous small-scale research in finding that biofeedback can help children with RSSD acquire American English /ɹ/. A companion study will compare participants' generalization learning after the end of all treatment. SUPPLEMENTAL MATERIAL: https://doi.org/10.23641/asha.29971501.

• Protocol for visual-acoustic intervention with service delivery in-person and via telepractice (VISIT) non-inferiority trial for residual speech sound disorder

  BMC Pediatrics · 2025-01-27 · 1 citations

  articleOpen accessSenior author

  BACKGROUND: Residual speech sound disorder (RSSD) is a high-prevalence condition that negatively impacts social and academic participation. Telepractice service delivery has the potential to expand access to technology-enhanced intervention methods that can help remediate RSSD, but it is not known whether remote service delivery is associated with a reduction in the efficacy of these methods. This project will systematically measure the outcomes of visual-acoustic biofeedback intervention when delivered in-person or online. METHODS/DESIGN: This project, Visual-acoustic Intervention with Service delivery In-person and via Telepractice (VISIT), aims to treat 76 children in a parallel randomized controlled clinical trial in which children with RSSD will receive visual-acoustic biofeedback treatment either in person or via telepractice. Eligible children will be speakers of American English aged 9-17 years who exhibit RSSD affecting /ɹ/ but otherwise show cognitive-linguistic and hearing abilities within the typical range. All participants will receive twenty sessions of visual-acoustic biofeedback; they will be randomized, with stratification by pre-treatment speech production ability and site, to complete their treatment sessions either in the laboratory setting or at home via telepractice. For the primary outcome measure, blinded listeners will evaluate changes in the perceived accuracy of /ɹ/ production after the end of treatment. DISCUSSION: By comparing outcomes in children randomized to receive a standard course of biofeedback treatment either via telepractice or in-person, this study will provide evidence-based guidance for clinicians seeking flexible service delivery options for a challenging and prevalent condition.
