Comparing Traditional Motor Speech Practice to Contextualized Speech Practice in Preschoolers With Childhood Apraxia of Speech.

PURPOSE: The aim of this study was to compare retention of real-word targets across practice conditions (contextualized vs. motor-only) within a modified integral stimulation treatment for preschoolers with childhood apraxia of speech (CAS). METHOD: A single-subject experimental design with alternating treatments was used with matched target sets randomly assigned to contextualized practice, motor-only practice, or no treatment. Three preschoolers with CAS completed 18 therapy sessions, each consisting of two 25-min blocks: one contextualized practice and one motor-only practice. Order of practice was randomized each visit. Changes in percent phonemes correct (PPC) and lexical stress accuracy, derived from blinded transcription, were explored with visual analysis and effect sizes (standardized mean difference, d statistic). RESULTS: Meaningful improvements (d > 1) were observed in PPC across words treated in contextualized practice for all three children immediately posttreatment and for two of three children at the 1-month follow-up. Meaningful improvements in the motor-only condition were observed in two of three children immediately posttreatment and at follow-up. No meaningful changes were observed in lexical stress across any conditions in any participant. CONCLUSIONS: This study provides preliminary support for the feasibility of a modified integral stimulation therapy that incorporates elements of linguistically grounded therapies (linguistic retrieval, recasts, expansions) that may facilitate target retention in some preschoolers with CAS. However, other elements should be explored in conjunction with integral stimulation to maximize clinical outcomes. SUPPLEMENTAL MATERIAL: https://doi.org/10.23641/asha.33228981.

Cost-Effectiveness and the Economics of Genomic Testing and Molecularly Matched Therapies.

Cost-effectiveness analysis of precision oncology can help guide value-driven care. Next-generation sequencing is increasingly cost-efficient over single gene testing because diagnostic algorithms require multiple individual gene tests to determine biomarker status. Matched targeted therapy is often not cost-effective due to the high cost associated with drug treatment. However, genomic profiling can promote cost-effective care by identifying patients who are unlikely to benefit from therapy. Additional applications of genomic profiling such as universal testing for hereditary cancer syndromes and germline testing in patients with cancer may represent cost-effective approaches compared with traditional history-based diagnostic methods.

Management of neonates born to mothers with reactive serologic tests for syphilis.

PURPOSE OF REVIEW: The dramatic resurgence of maternal and congenital syphilis in the United States highlights the need for their optimal management as syphilis in pregnancy can result in substantial neonatal morbidity and mortality. This review summarizes current epidemiology and discusses guidance on the management of neonates born to mothers with reactive serologic tests for syphilis. RECENT FINDINGS: Timely communication with local health department professionals is essential for optimal management of mothers with reactive serologic tests for syphilis and their neonates. Knowledge of maternal syphilis treatment history by partnering with local jurisdictions can circumvent much of the incertitude surrounding neonatal management. All neonates born to mothers with reactive serologic tests for syphilis should be tested using a nontreponemal ('lipoidal antigen') test. However, a reactive test may only indicate maternal nontreponemal IgG antibodies that are transferred transplacentally to the fetus. Therefore, neonatal management depends on maternal history and treatment for syphilis as well as clinical, laboratory, and radiographic findings in the neonatal evaluation. Existing management algorithms are complex, highlighting the need for a more practical, yet safe, approach. SUMMARY: A neonatal management guideline is proposed that may simplify the management of neonates born to mothers with reactive serologic tests for syphilis while advocating for expanded use of single-dose benzathine penicillin G therapy.

Imaging techniques for assessing the hand in systemic sclerosis: a systematic review.

BACKGROUND: Systemic sclerosis (SSc) is a rare autoimmune connective tissue disease frequently associated with hand involvement, leading to significant functional impairment. Imaging techniques provide unique opportunities to visualize and quantify structural and functional abnormalities of the hand, supporting diagnosis, monitoring, and treatment evaluation. This systematic review summarizes the imaging techniques used in SSc. METHODS: A systematic search of PubMed and Embase was conducted. Eligible studies included original research articles in English that applied or evaluated imaging techniques of the hands in SSc, published after 2000. Ultrasound and nailfold capillaroscopy were excluded, given their established use. Screening was performed independently by two authors. Findings were synthesized by clinical manifestations, study quality was assessed using the QUADAS-2 tool. RESULTS: Sixty-one studies met the inclusion criteria. In total, 25 distinct imaging techniques were identified, enabling assessment of various hand structures, including vascular involvement, inflammation, fibrosis, calcifications, erosions, and bone marrow edema. Vascular imaging was most extensively studied, particularly in the context of Raynaud's phenomenon and digital ischemia, with multiple techniques demonstrating impaired perfusion and altered thermoregulatory responses. MRI consistently detected subclinical inflammatory and erosive changes of joints and soft tissues,. CT-based techniques provided detailed assessment of calcinosis cutis, while optical and photoacoustic methods showed promise for quantifying skin fibrosis. CONCLUSION: Imaging techniques provide valuable, complementary insights into hand involvement in SSc, often revealing subclinical disease. Despite promising results, limited standardization and longitudinal validation currently restrict clinical implementation. Future studies should focus on harmonizing protocols and validating against clinically meaningful outcomes.

Brief Report: Beyond Testing: Exploring the Psychosocial Impact of HIV Self-Testing Among Ugandan Gender-Diverse Sex Workers.

BACKGROUND: The psychosocial effect of HIV self-testing (HIVST) on sex workers' self-esteem, depression, alcohol misuse, perceived sex work stigma, and empowerment remains poorly characterized. We hypothesized that HIVST would reduce sex work stigma and improve these psychosocial outcomes by enabling private, autonomous testing and reducing exposure to stigmatizing healthcare encounters. SETTING: Kampala, Uganda. METHODS: We conducted a secondary analysis of the Empower study (NCT03426670), an open-label randomized trial in which 117 cisgender female, transgender female, and cisgender male sex workers were assigned 1:1 to monthly HIVST plus quarterly clinic-based testing, or to quarterly clinic-based testing alone, and followed for 12 months. Self-esteem (Rosenberg Self-Esteem Scale), depressive symptoms (PHQ-2), alcohol misuse (RAPS4), perceived sex work stigma (adapted Female Sex Worker Stigma Scale), and empowerment were assessed quarterly. Mixed-effects regression models, adjusted for baseline values, evaluated intervention effects. RESULTS: Data from 117 participants were analyzed, including 7 early disenrollments. Over 12 months, HIVST participants reported significantly lower perceived sex work stigma than standard of care participants (β = -0.38, P = 0.04; monthly reduction P = 0.003), although the rate of decline did not differ significantly between arms (interaction P = 0.08). Self-esteem and depressive symptoms improved in both arms, with no between-arm differences (interaction P = 0.41 and 0.32). Alcohol misuse and empowerment showed no significant arm differences. CONCLUSION: HIVST may reduce sex work stigma without adverse psychosocial effects, supporting its integration into combination HIV prevention for gender-diverse sex workers in sub-Saharan Africa.

Effects of automated massage chair therapy on mental health and physical health: A comprehensive study.

BACKGROUND AND OBJECTIVE: Automated massage chair therapy is a non-pharmacological intervention widely believed to enhance wellness, yet evidence regarding its effects remains limited. This 3-part study evaluated the effects of automated massage chair therapy on mental and physical health. METHODS: In Part 1, 20 moderately stressed students were randomized to receive a 20-minute automated massage chair therapy session followed by a 20-minute control session, or vice versa, with a 48-hour washout period. Blood pressure (BP), heart rate (HR), electroencephalogram (EEG), State-Trait Anxiety Inventory (STAI), and Visual Analog Scale (VAS) were measured. In Part 2, 20 hypertensive hospital staff received three 20-minute automated massage chair therapy sessions on alternate days. BP, HR, and skin blood flow (SBF) were measured. In Part 3, 20 hospital staff with chronic low back pain received three 20-minute automated massage chair therapy sessions on alternate days. Electromyogram (EMG) and VAS were measured. RESULTS: Automated massage chair therapy significantly reduced diastolic blood pressure (DBP), HR, stress, and anxiety among moderately stressed students. In hospital staff with hypertension, SBF did not change significantly, whereas BP and HR decreased significantly after automated massage chair therapy. In hospital staff with chronic low back pain, low back function improved, and pain was significantly reduced after automated massage chair therapy. CONCLUSION: These findings indicate that automated massage chair therapy may help reduce stress, lower blood pressure, and alleviate low back pain.

Effect of Music on Pain, Anxiety, and Satisfaction During Intrauterine Device Application: A Randomized Clinical Trial.

This randomized controlled trial aimed to determine the effect of music played during intrauterine device (IUD) insertion on perceived pain, state anxiety, and satisfaction levels. The study was conducted with 70 women who applied to a maternal and child health and family planning center and were randomly assigned to the intervention and control groups using simple randomization. Data were collected using a Demographic Information Form, the State-Trait Anxiety Inventory (STAI-I), and the Visual Analog Scale (VAS), as well as Bluetooth speakers and the musical piece Evgeny Grinko-Valse. Participants in the intervention group listened to music before and during the IUD insertion procedure, whereas the control group received routine care only. Data were analyzed using SPSS version 26 with appropriate descriptive and inferential statistical methods. Women in the music group had significantly lower perceived pain (p&#x2009;<&#x2009;0.001) and state anxiety levels during the procedure (p&#x2009;=&#x2009;0.022), and significantly higher satisfaction levels compared with the control group (p&#x2009;<&#x2009;0.001). In addition, post-procedure state anxiety levels were positively correlated with pain intensity experienced during and after the procedure (r&#x2009;=&#x2009;0.542 and r&#x2009;=&#x2009;0.496, respectively; p&#x2009;<&#x2009;0.001), and negatively correlated with procedural satisfaction (r&#x2009;=&#x2009;-0.652; p&#x2009;<&#x2009;0.001). These findings suggest that listening to music during IUD insertion may help reduce pain and anxiety while potentially enhancing patient satisfaction. Trial Registration: NCT06215183.

Influence of Immediate Post-Bleaching Polishing on Enamel Color, Morphology, and Sensitivity: A Randomized Clinical Trial.

OBJECTIVE: This study evaluated the influence of polishing on enamel color change after in-office bleaching treatment on tooth morphology and sensitivity. MATERIALS AND METHODS: A total of 50 volunteers were randomized into two groups (n&#x2009;=&#x2009;25): in-office bleaching with 35% hydrogen peroxide gel for 45&#x2009;min without polishing (GSEM) or with polishing (GP). Color analysis was performed four times, at the beginning of the starting line and immediately after the first, second, and third bleaching sessions with a spectrophotometer. A qualitative analysis of enamel morphology was performed under a scanning electron microscope. Tooth sensitivity was assessed daily using the Visual Analog Scale (&#x3b1;&#x2009;=&#x2009;0.05). RESULTS: There was no statistically significant difference (p&#x2009;>&#x2009;0.05) in tooth color change when comparing &#x394;E, &#x394;E00, and &#x394;WID between the groups. The enamel surface showed larger areas of irregularities and depressions in the GP group than in the GSEM group. There was no difference in tooth sensitivity (p&#x2009;>&#x2009;0.05) between the groups. CONCLUSIONS: Polishing after whitening in the office does not change the color and sensitivity of the tooth but promotes greater changes in the morphology of the enamel, such as increased surface roughness. CLINICAL RELEVANCE: Polishing immediately after teeth whitening causes greater changes in enamel surface morphology.

Selective Neurectomy Outcomes in Synkinesis Patients: The First 56 Consecutive Primary Cases with Minimum 1-Year Follow-Up.

INTRODUCTION: Evaluation of 1-year follow-up outcomes after selective neurectomy (SN) is essential to confirm sustained improvements in patient-reported, clinician-graded, and objective results. OBJECTIVE: To assess outcomes of SN in synkinesis, using patient-reported outcomes (VAS), clinician-graded assessments (eFACE), and objective evaluations. METHODS: Synkinesis patients who underwent SN were included in the study. Patients with less than 12 months of follow-up were excluded. Visual analog scale (VAS) was assessed as patient-reported outcomes. The Electronic Clinician-Graded Facial Function Scale (eFACE) was also assessed. Objective evaluations were carried out via Emotrics Software. RESULTS: Fifty-six primary cases were included, with a mean patient age at surgery of 33.8&#x2009;&#xb1;&#x2009;11.0 years. Of these, 45 patients (80.3%) were female. The average duration between paralysis and surgery was 124.3&#x2009;&#xb1;&#x2009;103.3 months. The mean duration between surgery and evaluation was 19.7&#x2009;&#xb1;&#x2009;7.5 months (mean/SD). Preoperative and postoperative mean aggregate VAS scores were 35.5&#x2009;&#xb1;&#x2009;19.8 and 67.7&#x2009;&#xb1;&#x2009;16.5, respectively (p < 0.001). However, two patients (3.7%) reported worsening in moving food around in the mouth, and four patients (7.5%) reported worsening in drooling. All postoperative eFACE subscores except periocular demonstrated significant improvement (p < 0.001). Emotrics analysis demonstrated improvement in all postoperative symmetry parameters, except in the periocular region. CONCLUSIONS: SN improves patient-reported outcomes, clinician-graded assessments, and objective measurements. However, periocular outcomes remain suboptimal, and functional deficits should be carefully considered.

Effectiveness of symptom map-based education in the management of premenstrual syndrome: a randomized controlled trial.

PURPOSE: To evaluate the effectiveness of a symptom map-based educational intervention for the non-pharmacological management of premenstrual syndrome (PMS), with a focus on symptom reduction among women with differing baseline symptom severity. METHODS: This randomized controlled study was conducted between May and December 2024. A total of 110 women meeting diagnostic criteria for PMS were randomly assigned to an intervention group (n = 55) or a control group (n = 55) using block randomization, and 101 participants completed follow-up assessments. The intervention comprised structured education based on a PMS symptom map and evidence-based self-care strategies. Outcomes included PMS symptom severity (Premenstrual Syndrome Scale), pain intensity (Visual Analog Scale), psychological symptoms (Depression Anxiety Stress Scale-21), and PMS-specific life satisfaction. CLINICAL TRIAL REGISTRATION: NCT06585475. RESULTS: Compared with the control group, women in the intervention group reported significantly lower pain (adjusted mean 4.21 vs. 6.81, p < .001) and stress levels (8.54 vs. 12.03, p < .001) at follow-up. The intervention was particularly effective in reducing PMS symptom severity and depressive symptoms among participants with higher baseline symptom burden. Improvements in PMS-specific life satisfaction were observed, with reductions in depressive symptoms contributing to this effect. CONCLUSION: A symptom map-based educational intervention is a clinically applicable, non-pharmacological approach for PMS management. This structured education appears especially beneficial for women with more severe baseline symptoms and may be integrated into routine gynecological care to support individualized symptom management.

Genomic insights into end-use grain quality and nutritional traits of an ancient Indian dwarf wheat ( Triticum sphaerococcum Percival) population using a multi-locus genome-wide association study.

BACKGROUND: Triticum sphaerococcum, an ancient hexaploid wheat species, is renowned for its stress resilience and superior nutritional quality. A panel of 116&#x2009;T. sphaerococcum accessions (the largest known collection at a single site globally), with six bread wheat released varieties, was evaluated for its potential for genetic quality improvement. Field experiments were conducted under standard, heat and moisture-deficit conditions across two cropping seasons for ten grain end-use quality and nutritional traits. RESULTS: Genotypes showed highly significant differences (P&#x2009;&#x2264;&#x2009;0.001) for measured traits, with high broad-sense heritability resulting from substantial genotypic variance contributions. Triticum sphaerococcum consistently outperformed T. aestivum across environments, with moisture-deficit stress proving more detrimental to quality parameters than heat stress, while micronutrient content increased under stressed conditions. Trait correlations revealed that the gluten index (GI) correlated negatively with the grain hardness index (GHI), wet gluten (WG), and water-binding capacity (WB), while positively correlating with dry gluten (DG) and protein content (PRO), whereas grain iron (GFE), zinc (GZN), and protein showed consistent positive interrelationships. Two superior accessions, PAUTS10 (WG 35.13%, DG 13.71%, PRO 16.42%, GZN 50.89&#x2009;ppm) and Sonamoti (WG 33.33%, DG 12.92%, PRO 16.27%, GZN 56.03&#x2009;ppm), were identified, surpassing the best check variety HD3226 for quality and nutritional parameters. Multi-locus genome-wide association studies identified 30 stable quantitative trait nucleotides across environments, with candidate gene analysis revealing genes involved in transcription regulation, biosynthetic processes, metal ion homeostasis, and transport. CONCLUSIONS: Triticum sphaerococcum demonstrated superior grain quality and micronutrient potential compared with modern wheat, highlighting its value as a genetic resource for biofortification. The identification of elite accessions and stable quantitative trait nucleotides (QTNs) provides useful targets for breeding programs aimed at improving protein and micronutrient content. Integrating ancient germplasm with modern genomic tools can accelerate the development of nutritionally enhanced wheat varieties. &#xa9; 2026 Society of Chemical Industry.

Early infantile developmental and epileptic encephalopathy: clinical spectrum, diagnosis, outcomes, and evolving treatment strategies.

Early infantile developmental and epileptic encephalopathy (EIDEE) is among the most severe epilepsy syndromes, with onset before three months of age and an estimated incidence of approximately 10 per 100,000 live births. The 2022 International League Against Epilepsy classification unified the historically distinct Ohtahara syndrome and early myoclonic encephalopathy under a single diagnostic framework defined by frequent drug-resistant tonic and/or myoclonic seizures, an abnormal neurological examination, and an abnormal interictal electroencephalogram-most characteristically a burst-suppression pattern. This narrative review synthesizes the clinical, electrophysiological, neuroimaging, genetic, and therapeutic literature within the EIDEE framework. The clinical phenotype is characterized by central hypotonia, postnatal microcephaly, cortical visual impairment, and age-dependent syndromic evolution toward infantile epileptic spasms syndrome or Lennox-Gastaut syndrome in the majority of patients. Electroencephalography remains essential for syndromic classification, while systematic metabolic screening and early trio whole-exome or whole-genome sequencing are central to the etiologic workup, achieving diagnostic yields of 60-65%. The most commonly identified genetic causes include STXBP1, KCNQ2, and SCN2A variants. Outcomes are poor overall and strongly etiology-dependent: vitamin-responsive disorders carry a substantially more favorable prognosis, whereas mortality reaches 25% in genetic cohorts. Genotype-guided pharmacotherapy is now applicable to a clinically meaningful subset of patients, with sodium channel blockers, potassium channel openers, and emerging antisense oligonucleotide therapies representing important therapeutic advances. Gene therapy trials are underway but have encountered early safety signals, underscoring the vulnerability of this population. Critical unmet needs include earlier molecular diagnosis, precision therapies targeting developmental outcomes beyond seizure control, and prospective international registries to characterize the long-term natural history of EIDEE.

Performance of Photon-counting CT for Assessing Pretreatment Breast Cancer: Comparison with Mammography, MRI, and 18F-FDG PET/CT.

Background Photon-counting CT (PCCT) offers improved spatial resolution, contrast to noise ratio, and dose efficiency, but its clinical utility remains incompletely defined for breast cancer. Purpose To evaluate the feasibility of PCCT for pretreatment breast cancer assessment through comparisons with MRI, full-field digital mammography (FFDM), and fluorine 18 (18F) fluorodeoxyglucose (FDG) PET/CT. Materials and Methods In this prospective study (March-May 2025), female participants with breast lesions categorized as Breast Imaging Reporting and Data System 4C or higher at US or FFDM underwent breast MRI and multiphasic contrast-enhanced PCCT. 18F-FDG PET/CT was performed in a subset with locally advanced disease. Four radiologists independently evaluated lesion morphologic characteristics, additional findings, and clinical TNM stage. Agreement was analyzed using intraclass correlation coefficients (ICCs) and &#x3ba; statistics. The diagnostic performance for additional lesions and nodal metastasis was compared with the reference standard (pathologic examination). Results Among 126 participants (mean age, 58.1 years &#xb1; 12.3 [SD]), interreader agreement across PCCT, MRI, and FFDM was good to excellent. PCCT agreed with MRI for lesion characterization (&#x3ba; = 0.57-0.96) and clinical T categorization (&#x3ba; = 0.86-0.88), with highest agreement with pathologic size (ICC, 0.70-0.81). For 46 pathologically confirmed additional lesions, PCCT was more sensitive than FFDM (difference, 44% [95% CI: 19, 66]) and similar to MRI (difference, 7% [95% CI: -5, 21]). Additionally, 44% (95% CI: 27, 52) of microcalcifications were missed at PCCT versus FFDM. For pathologically confirmed nodal metastasis, PCCT was more sensitive (difference, 10% [95% CI: 1, 20]) and accurate (difference, 6% [95% CI: 1, 11]) than MRI. For clinical N category, PCCT agreed with PET/CT (&#x3ba; = 0.82 [95% CI: 0.62, 0.96]; n = 19). Two distant metastases identified at PCCT were consistent with 18F-FDG PET/CT and pathologic findings. Conclusion PCCT demonstrated similar performance to MRI for lesion characterization and detection of additional lesions, with better performance for nodal metastasis evaluation; however, detection of microcalcifications was limited. &#xa9; RSNA, 2026 Supplemental material is available for this article.

Extragenital testing for gonorrhea and chlamydia in health department clinics in Virginia, 2018-2023.

BACKGROUND: Extragenital testing for chlamydia and gonorrhea infections is now routine in many settings. We assessed temporal and demographic trends in extragenital testing and positivity in public health department clinics in Virginia. METHODS: We analyzed urogenital and extragenital chlamydia/gonorrhea laboratory results for clients aged 15 years or older who attended 116 health department clinics from 2018 to 2023. Test volume and positivity was stratified by anatomic site, year, sex, and age. RESULTS: There were 181,471 client visits with valid test results. The proportion of visits with any extragenital testing increased from 19% to 46% during this time. Male clients were twice as likely as females to receive pharyngeal testing (46% vs. 22%) and five times as likely to be tested rectally (15% vs. 3%). Rectal specimen positivity surpassed urogenital positivity for chlamydia (females and males) and gonorrhea (males only). Overall, one-quarter of clients diagnosed with gonorrhea infections were identified exclusively through extragenital testing, as were 9% of clients with positive chlamydia tests. These proportions increased over time and were greater for younger clients and for males relative to females. Two-thirds of extragenital infections would have been missed by urogenital testing alone, including 40% and 49% of females and 86% and 73% of males with extragenital chlamydia and gonorrhea infections respectively. CONCLUSIONS: The proportion of clients who received extragenital chlamydia/gonorrhea testing increased over time, extragenital test positivity was high, and it identified infections that would have been missed otherwise. The impact on sexually transmitted infection sequelae and transmission remains unclear.

Perceptions of Pharmacogenomic Testing Among People With Treatment Resistant Depression: Legitimization as a Facilitator of Acceptance.

Pharmacogenomic testing for psychiatric medications has been proposed as both an early intervention to optimize treatment response, and for use among patients who have tried multiple medications without symptom remission. Therefore, this testing may be particularly salient to the subset of individuals with major depressive disorder for whom depression has been labeled as "treatment resistant". Understanding the impact of this diagnostic label on illness identity and attitudes towards new therapies is important as genomic technology expands and rates of depression increase. We sought to explore perceptions and attitudes towards pharmacogenomic testing among individuals who had received a diagnosis of treatment resistant depression. We conducted a qualitative study with a constructivist orientation. Participants were recruited from a larger genomic research study and interviewed by phone or video call. We took an inductive approach to coding guided by reflexive thematic analysis. Themes were then organized into a relational framework following principles of interpretive description. Twelve individuals were interviewed. Key themes included internalized acceptance/hopelessness, and external validation/frustration, which were cyclically interconnected. These themes were situated within a larger framework illustrating the ways that illness identity and modifying factors such as relief of guilt, social support, pharmacogenomic testing and depressive symptoms can either facilitate acceptance and validation or contribute to feelings of hopelessness and frustration. Though participants expressed some skepticism around its effectiveness, pharmacogenomic testing may contribute to the shift towards acceptance and validation by legitimizing individuals' experiences with lack of treatment response. Genetic counselors and other healthcare providers should be aware of the complex balance between hope and frustration underlying conversations around pharmacogenomic testing, and factors that are more likely to foster self-acceptance.

Financial incentives and social messaging for repeat SARS-CoV-2 antibody testing among the underserved: A randomized trial.

Financial incentives may influence health behavior beyond their expected monetary value, and their effectiveness may depend on how the behavior is framed. Behavioral theories of decision making suggest that individuals may value protection against small-stakes losses more than expected utility predicts, while theories of family-centered health behavior suggest that messages emphasizing benefits to family members may strengthen participation in preventive health activities. We tested these ideas in a 2&#xd7;2 factorial randomized trial involving 625 households recruited from a Federally Qualified Health Center serving low-income Latino/Hispanic communities. Participants completed repeat SARS-CoV-2 antibody testing. The trial crossed two messaging strategies (Family vs. Personal) with two incentive structures (Loss Protection vs. Lottery) that offered equivalent expected monetary value. Family Messaging emphasized protecting one's family from COVID-19, whereas Personal Messaging emphasized protecting oneself. Loss Protection allowed participants to secure an at-risk reward through repeat testing, whereas the Lottery condition offered a chance of a large reward. Repeat testing was approximately 8 percentage points higher under Family Messaging and 7 percentage points higher under Loss Protection. Baseline trust in medical providers, financial barriers to vaccination, and risk aversion were associated with initial testing, whereas household characteristics were not associated with repeat testing. Incentive design may matter beyond expected monetary value and that framing health behaviors in terms of family welfare may increase participation in repeated healthy activities. Broadly, the results support behavioral theories emphasizing loss aversion, anticipated regret, and family-centered motivations, and suggest practical approaches for improving engagement in repeat health behaviors.

The effects of fitspiration TikTok content on body image and mood among young adult women in the U.S.

Fitspiration is an appearance-based form of media that promotes physical fitness and dieting. While not true of all fitspiration media, some forms promote these ideals through visuals of toned, athletic bodies that have become increasingly prevalent on the short-form video platform, TikTok. Although often framed as health-promoting, fitspiration exposure has been associated with upward appearance comparison (i.e., comparison with people perceived as more attractive) and negative effects on body image and mood. The present study investigated the effects of short-form video-based fitspiration on social comparison, appearance importance, appearance anxiety, body dissatisfaction, and negative affect. Using an experimental design, 150 undergraduate women (Mage = 19.28) in the United States were randomly assigned to view a five-minute TikTok compilation of either animal (n&#x202f;=&#x202f;75) or fitspiration videos (n&#x202f;=&#x202f;75). Participants completed baseline measures prior to viewing and state-level measures after completing their video set. Results indicated that, relative to control, viewing fitspiration content led to greater social comparison, appearance concerns, feelings of being fat, and sadness. Baseline appearance concerns and depressive symptoms significantly moderated group differences in responses, such that negative fitspiration effects on state-level appearance concerns were found among individuals high but not low in baseline appearance concerns and among individuals low but not high in baseline depressive symptoms. These findings contribute to the growing literature on fitspiration by demonstrating the immediate psychological effects of this content in short-form videos and highlighting the importance of considering individual differences in vulnerability.
