RESUMEN

Increased attention is arising on the delivery of remote cognitive interventions, which allow performing exercises in everyday settings, favouring rehabilitation continuity. The present study offers an overview of remote cognitive training programs for children with congenital brain malformation or genetic syndrome affecting the central nervous system, included in papers published in the time period 2011-2021. A total of 13 records was found and discussed including efficacy studies, feasibility studies and study protocols. Many studies have focused on a specific diagnosis, such as cerebral palsy, Down Syndrome, Fragile X Syndrome, while no or little evidence has been gathered on more rare diseases or brain malformations. Interventions were found to generate benefits on some cognitive functions, but problems with adherence were highlighted, especially due to excessive cognitive load from the training or clinical comorbidities. Conclusions remain tentative due to heterogeneity in training, study and patients characteristics, and methodological limitations of studies.

RESUMEN

Individuals with acquired brain injury (ABI) commonly present with impairments in cognitive abilities. As these competencies seem to be predictive of patients' abilities to reintegrate into the everyday settings, it is crucial to assess them properly. However, previous research has indicated that patients may perform relatively well on standard tests of cognitive functioning, but may nonetheless encounter significant difficulties in organizing and executing everyday tasks. In order to overcome this issue, virtual reality (VR) methods have been introduced in clinical practice with the aim of creating assessments that simulate real-world activities and thus, provide a clearer picture of patients' functioning in everyday settings. This review offers an overview of VR assessment tools described in the scientific literature between 2010 and 2019. Overall, 38 relevant records describing 31 different tools were found. Among these tools, 16 assessed executive functions and prospective memory, while the other 15 assessed visuo-spatial abilities. Although promising results have been reported, our analysis indicated that about half of the tools deliver tasks that differ from everyday activities, thus limiting the generalizability of patients' performance to the real-world. Moreover, a variety of methodological shortfalls related to study Internal and External Validity have been highlighted, which hamper the possibility of drawing definite recommendations on tool choice. These limitations suggest the importance of putting considerable efforts into the improvement or development of VR tools for patients with ABI for both research and clinical purposes, considering the great potential of this form of assessment.

RESUMEN

Despite the importance of reptiles in agroecosystems, little is known about the effects of agricultural intensification and pesticide use on these animals. We compared antioxidant and haematological biomarkers in the wild Italian wall lizards Podarcis siculus from three olive groves representing a gradient of management intensity. Lizards from the conventional grove showed induced antioxidant defences relative to those from the organic field. However, this induction did not avoid the occurrence of oxidative stress in males from intensively managed olive groves, who showed TBARS levels 58%-133% higher than males from the other sites. Haematological responses also suggested increased stress in females from the intensively managed olive groves, with a heterophil-to-lymphocyte ratio 5.3 to 14.8-fold higher than in the other sites. The observed stress responses of lizards along the studied gradient of agricultural management suggest their potential usefulness as non-destructive biomarkers to environmental stressors associated with agricultural intensification.

RESUMEN

Computerized cognitive training programs (CCTP) are based on the assumption that cognitive abilities may be boosted by repetitively performing challenging tasks. The integration of game-like features in these programs, associated with the goal of amusing or rewarding participants, may contribute to generate cognitive benefits. Indeed, reinforcement contingencies have been reported to produce positive effects on performance and motivation, especially in children. This meta-analysis was aimed at providing a quantitative summary of the effectiveness of CCTP with game-like features in school-aged children with typical and atypical development. A total of 24 studies, with the cognitive and behavioral outcome data of 1547 participants, were selected for inclusion in the meta-analysis. Subgroup analyses were performed to identify the sources of the observed methodological heterogeneity. A robust variance estimation model, after removal of study outliers, yielded a small-to-moderate significant effect size. Final results pointed out smaller but more precise estimate effect sizes according to methodological aspects related to cognitive domain of outcomes, standardization of measures and type of control applied. Alongside supporting the use of CCTP for rehabilitating cognitive functions, the present results shed light on how different methodological choices are able to shape research findings in the field of children's cognitive rehabilitation.

RESUMEN

Predictive coding accounts of action perception sustain that kinematics information is compared with contextual top-down predictions (i.e., priors) to understand actions in conditions of perceptual ambiguity. It has been previously shown that the cerebellum contributes to motor simulation of observed actions. Here, we tested the hypothesis that a specific contribution of the cerebellum to action perception is to provide contextual priors that guide the sampling of perceptual kinematic information. To this aim, we compared the performance of 42 patients with childhood brain tumor affecting infratentorial (ITT) or supratentorial (STT) areas with that of peers with typical development in an action prediction task. First, participants were exposed to videos depicting a child performing different reaching-to-grasp actions, which were associated with contextual cues in a probabilistic fashion. Then, they were presented with shortened versions of the same videos and asked to infer the action outcome; since kinematics was ambiguous, we expected their responses would be biased toward the previously learned contextual priors. We found that patients with brain tumor were impaired in predicting actions when compared to healthy controls. However, STT patients presented a reliable probabilistic effect, while ITT patients, who had cerebellar damage, did not rely on contextual priors in predicting actions. Furthermore, we found an association between the use of contextual priors and the ability to infer others' mental states as assessed by a standardized test. These results suggest that the cerebellum provides contextual priors to understand others' actions and this predictive function might underlie complex social cognition abilities.

RESUMEN

PURPOSE: Effects of tumor location on cognitive performance of patients with brain tumor are controversial: some studies reported higher risks related to supratentorial locations, some to infratentorial locations, and still others did not find any differences. We aimed to address this issue by comparing school-aged children with supratentorial or infratentorial tumor with respect not only to cognitive outcomes but also to the associations between core cognitive domains and academic abilities. METHODS: 32 children with infratentorial tumor and 22 with supratentorial tumor participated in the study. To detect relationships among cognitive domains, we tested which neuropsychological variable(s) predicted academic skills, controlling for the effects of radiotherapy and time since diagnosis. RESULTS: Radiotherapy and time since diagnosis, but not tumor location, predicted cognitive outcomes. Radiotherapy negatively influenced attention and executive functioning, as well as reading speed and arithmetic operations accuracy. Unexpectedly, longer time since diagnosis was associated with improvement in attention and reading speed. Tumor location showed an effect on the relationships between core cognitive domains and academic skills: verbal and visual-spatial memory influenced reading and mathematical performance in supratentorial patients; in infratentorial patients, an only effect of visual-spatial memory on mathematical performance was detected. CONCLUSIONS: Tumor location seems not to influence cognitive performance, while radiotherapy constitutes a key risk factor for cognitive impairment. Attentional and reading abilities may improve over time, possibly due to the weakening of cancer care effects. Different patterns of cognitive associations seem to characterize supratentorial and infratentorial patients, probably associated with different neuroplastic reorganization processes after tumor occurrence.

RESUMEN

The novel coronavirus, COVID-19, has led to sweeping changes in psychological practice and the concomitant rapid uptake of telepsychotherapy. Although telepsychotherapy is new to many clinical psychologists, there is considerable research on telepsychotherapy treatments. Nearly 2 decades of clinical research on telepsychotherapy treatments with children with neurological conditions has the potential to inform emerging clinical practice in the age of COVID-19. Toward that end, we synthesized findings from 14 clinical trials of telepsychotherapy problem-solving and parent-training interventions involving more than 800 children and families with diverse diagnoses, including traumatic brain injury, epilepsy, brain tumors, congenital heart disease, and perinatal stroke. We summarize efficacy across studies and clinical populations and report feasibility and acceptability data from the perspectives of parents, children, and psychotherapists. We describe adaptation for international contexts and strategies for troubleshooting technological challenges and working with families of varying socioeconomic strata. The extensive research literature reviewed and synthesized provides considerable support for the utility of telepsychotherapy with children with neurological conditions and their families and underscores its high level of acceptability with both diverse clinical populations and providers. During this period of heightened vulnerability and stress and reduced access to usual supports and services, telepsychotherapy approaches such as online family problem-solving treatment and online parenting skills training may allow psychologists to deliver traditional evidence-based treatments virtually while preserving fidelity and efficacy.


El nuevo coronavirus, COVID-19, ha conducido a cambios radicales en la psicología. práctica y el rápido consumo concomitante de telepsicoterapia. A pesar de que la telepsicoterapia es nueva para muchos psicólogos clínicos, existe una investigación considerable sobre tratamientos de telepsicoterapia. Casi dos décadas de investigación clínica sobre los tratamientos de telepsicoterapia con niños con afecciones neurológicas tienen la potencial para informar la práctica clínica emergente en la edad de COVID-19. Hacia ese fin, sintetizamos los resultados de 14 ensayos clínicos de resolución de problemas de telepsicoterapia e intervenciones de capacitación para padres que involucran a más de 800 niños y familias con diagnósticos diversos que incluyen lesión cerebral traumática, epilepsia, tumores cerebrales, enfermedad cardíaca congénita y accidente cerebrovascular perinatal. Resumimos la eficacia entre los estudios y poblaciones clínicas e reportamos datos de viabilidad y aceptabilidad desde las perspectivas de padres, hijos y psicoterapeutas. Describimos adaptacion para contextos internacionales y estrategias para resolver problemas tecnológicos y trabajar con familias de estratos socioeconómicos variables. La extensa literatura de investigación revisada y sintetizado proporciona un apoyo considerable para la utilidad de la telepsicoterapia con niños con afecciones neurológicas y sus familias y subraya su alto nivel de aceptabilidad con diversas poblaciones clínicas y proveedores. Durante este período de mayor vulnerabilidad y estrés y menor acceso a los apoyos habituales y servicios, enfoques de telepsicoterapia como tratamiento em línea para resolución de problemas familiares y la capacitación en habilidades para padres en línea pueden permitir que los psicólogos brinden tratamientos tradicionales basados en evidencia virtualmente mientras se preserva la fidelidad y la eficacia.

RESUMEN

PURPOSE: The female gender has been considered a risk factor for cognitive impairment in pediatric brain tumor survivors. However, it is still unknown which specific cognitive domains are at greater risk of impairment in females. The aim of this study was to explore differences between male and female children in distinct domains of cognitive functioning, in order to deepen knowledge on the topic. METHODS: The cognitive performance of 100 males and 71 females aged 6-16 years was assessed by Wechsler Intelligence Scales for Children-Third Edition (WISC-III). Differences between males and females were tested not only on intellectual quotients, but also on WISC-III subtests, which allow the evaluation of different cognitive domains. Analyses were performed in the whole sample and dividing children based on the supratentorial vs. infratentorial location of the tumor. RESULTS: Gender was the only predictor of VIQ in the whole group and in children with supratentorial tumor. Female children with supratentorial tumor performed significantly worse than males in four out of six verbal subtests. However, even among children with infratentorial tumor, females performed worse than males on two verbal subtests. CONCLUSIONS: Overall, findings of this study suggest that females may have more difficulties than males at manipulating verbal oral material. A possible explanation of these findings could be that females present a greater vulnerability to white matter damage due to the illness and post-adjuvant therapies, in line with reports of the literature on female children with lymphoblastic leukemia.

RESUMEN

Darevskia rock lizards include both sexual and parthenogenetic species, mostly distributed in the heterogeneous and ecologically diverse Caucasus. The parthenogenetic species originated via directional hybridogenesis, with only some of the sexual species known to serve as parentals. However, it remains unclear when and where these events happened and how many parental lineages were involved. A multilocus phylogeographic analysis was performed on the parthenogens D. unisexualis, D. bendimahiensis and D. uzzeli, and their putative maternal species D. raddei. Results show the parthenogenetic species all have relatively recent origins, approximately 200-70kyr ago, and at least three hybridization events were involved in their formation. Ecological niche models identify the region where hybridization events leading to the formation of D. unisexualis took place, namely in the northeast of the current distribution. Models also suggest that the sexual D. raddei might have undergone a habitat shift between the Last Interglacial and the Last Glacial Maximum.

RESUMEN

The ongoing biodiversity crisis is strongly threatening amphibians, mostly because of their peculiar physiology, their sensitivity to climate change and the spread of diseases. Effective monitoring involving assessments of pressure effects across time and estimation of population trends play a key role in mitigating amphibian decline. To improve implementation of standardized protocols and conservation efforts, we present here a dataset related to one of the amphibian genera whose onservation status is considered the most declining according to the IUCN. We report information on 66 populations of the endangered European cave salamanders, genus Speleomantes, that was collected through a standardized monitoring along a four-year period (2021-2024). Demographics data of the populations and fitness-related data of single individuals are reported. Furthermore, we include 3,836 high quality images of individuals that can allow to perform studies aiming to assess the phenotypic variability within the genus, and to perform long-term capture-mark-recaptured studies.

RESUMEN

The Tuscan Archipelago is one of the most ancient and ecologically heterogeneous island systems in the Mediterranean. The biodiversity of these islands was strongly shaped by the Pliocene and Pleistocene sea regressions and transgression, resulting in different waves of colonization and isolation of species coming from the mainland. The Italian wall lizard, Podarcis siculus, is present on the following islands of the Tuscan Archipelago: Elba, Giglio, Giannutri, Capraia, Montecristo and Cerboli. The species in the area displays a relatively high morphological variability that in the past led to the description of several subspecies. In this study, both the genetic and morphological diversity of P. siculus of the Tuscan Archipelago were investigated. Specifically, the meristic characters and the dorsal pattern were analyzed, while the genetic relationships among these populations were explored with mtDNA and microsatellite nuclear markers to reconstruct the colonization history of the Archipelago. Our results converge in the identification of at least two different waves of colonization in the Archipelago: Elba, and the populations of Cerboli and Montecristo probably originate from historical introductions from mainland Tuscany, while those of Giglio and Capraia are surviving populations of an ancient lineage which colonized the Tuscan Archipelago during the Pliocene and which shares a common ancestry with the P. siculus populations of south-eastern Italy. Giannutri perhaps represents an interesting case of hybridization between the populations from mainland Tuscany and the Giglio-Capraia clade. Based on the high phenotypic and molecular distinctiveness of this ancient clade, these populations should be treated as distinct units deserving conservation and management efforts as well as further investigation to assess their taxonomic status.

RESUMEN

Both acquired injuries and congenital malformations often cause lifelong disabilities in children, with a significant impact on cognitive abilities. Remote computerized cognitive training (CCT) may be delivered in ecological settings to favour rehabilitation continuity. This randomized clinical trial (RCT) evaluated the efficacy of an 8-week multi-domain, home-based CCT in a sample of patients aged 11-16 years with non-progressive acquired brain injury (ABI), brain tumor (BT) and congenital brain malformation (CBM). Following a stepped-wedge research design, patients were randomized into two groups: Training-first group, which started the CCT immediately after baseline assessment and Waiting-first group, which started the CCT after a period of time comparable to that required by the training (8 weeks). Post-training and long-term (6 months) changes were assessed. Both groups improved on visual-spatial working memory after the CCT, with benefits maintained after 6 months, while no other changes in cognitive or psychological measures were found. These findings suggest that a multi-domain CCT can generate benefits in visual-spatial working memory, in accordance with data from extant literature reporting that computer games heavily engage visuo-spatial abilities. We speculate that is tapping on the same cognitive ability with a prolonged training that may generate the greatest change after a CCT.

RESUMEN

Dysfunctions in body processing have been documented in adults with brain damage, while limited information is available for children. This study aimed to investigate body processing in children and adolescents with traumatic brain injury (TBI) (N = 33), compared to peers with typical development. Two well-known computerized body-representation paradigms, namely Visual Body Recognition and Visuo-spatial Imagery, were administered. Through the first paradigm, the body inversion and composite illusion effects were tested with a matching to sample task as measures of configural and holistic processing of others' bodies, respectively. The second paradigm investigated with a laterality judgement task the ability to perform first-person and object-based mental spatial transformations of own body and external objects, respectively. Body stimuli did not convey any emotional contents or symbolic meanings. Patients with TBI had difficulties with mental transformations of both body and object stimuli, displaying deficits in motor and visual imagery abilities, not limited to body processing. Therefore, cognitive rehabilitation of body processing in TBI might benefit from the inclusion of both general training on visuo-spatial abilities and specific exercises aimed at boosting visual body perception and motor imagery.

RESUMEN

The trophic niche of a species is one of the fundamental traits of species biology. The ideal trophic niche of a species is realized in the absence of interspecific competition, targeting the most profitable and easy-to-handle food resources. However, when a competitor is present, species adopt different strategies to reduce competition and promote coexistence. In this study, we assessed the potential mechanisms that allow the coexistence of two generalist salamanders: the Italian cave salamander (Speleomantes italicus) and the fire salamander (Salamandra salamandra). We surveyed, in April 2021, a forested area of Emilia-Romagna (Italy) during rainy nights. Analyzing the stomach contents of the captured individuals, we obtained information on the trophic niche of these two sympatric populations. Comparing our results with those of previous studies, we found that the two species did not modify their trophic niche, but that alternative mechanisms allowed their coexistence. Specifically, different prey preferences and predator metabolisms were likely the major factors allowing reduced competition between these two generalist predators.

RESUMEN

The determination of a species trophic niche can clarify its functional role within a food web and how prey resources are used in relation with the spatial and temporal variability of environmental conditions. This information may result particularly useful for the implementation of conservation plans of endangered species having a cryptic behaviour or living in places difficult to be surveyed. Here we present the first long-term study on the trophic niche of the Italian cave salamander Speleomantes italicus, a strictly protected facultative cave species that seasonally exploits surface environments (e.g., forested areas) as well as both natural and artificial subterranean environments. We analysed the diet variation of six populations of S. italicus inhabiting natural caves, surveyed 24 times in a full year. During the surveys, all sampled individuals were subjected to stomach flushing and the ingested prey were identified and enumerated; furthermore, salamanders' body condition was also evaluated. The results of the analyses provided the first comprehensive, year-round assessment of the diet for a Speleomantes species. Remarkable divergences in terms of trophic niche and body condition were observed between the studied populations. We found a discrepancy in the foraging activity of the populations located in different areas; specifically, the individuals that experienced sub-optimal microclimatic conditions poorly performed in foraging. Furthermore, we found temporal and spatial variability in the body condition of individuals. Our study highlighted a remarkably high spatial and temporal divergence in the trophic habits of conspecific populations, a feature that may represent one of the major factors promoting the variability of multiple population traits.

RESUMEN

This data set collects capture-mark-recapture data, biometric data, and stomach contents of seven populations of the Italian cave salamander (Speleomantes italicus), one of the strictly protected European plethodontid species endemic to mainland Italy. We monitored six subterranean populations inside caves, and one fully epigean population living in a forest, surveying a total area of >5200 m2 . Data collection was performed 24 times throughout a year for each of the subterranean populations, and seven times in late winter-early spring for the epigean population. Salamanders were individually identified using two different marking methods: subcutaneous injection of visual implant elastomers (VIE) and photographic recognition of the dorsal pattern. Overall, the data set contains information on 1283 captured salamanders, corresponding to 783 different individuals and 500 recapture events. This type of data can be used to assess the species detection probability and to estimate the size of the populations, which are fundamental parameters for the assessment of its conservation status. Captured salamanders were weighed using a digital scale and photographed next to a reference ruler to perform post hoc measurements. This allows to assess the potential variation of the body condition of individuals through the time, and the potential divergences between conspecific populations. Furthermore, repeated measurements of recaptured individuals can allow to evaluate the seasonal growth rates of Speleomantes. Before their release, the salamanders underwent stomach flushing, a non-invasive technique that allows us to investigate the food residues in the salamanders' stomach. In 951 salamanders, we were able to recognize a total of 7077 consumed prey items belonging to 37 different prey categories (i.e., order level or lower), completing the information on the consumed prey for the entire Speleomantes genus. Data on consumed prey can be used to assess potential divergences between populations or between individuals of different ages/sexes, but also to assess the potential trophic specialization of individuals. The distinctiveness of this data set is that, by combining the capture-mark-recapture data with those on the diet of individuals, it allows to perform detailed studies on the consistency of individuals' food preference over time, an analysis that has never been performed on these salamanders. We release the data set into the public domain under Creative Commons Attribution 4.0 International license (CC-BY). When you use this data in your publication, we request that you cite this data paper; if you are using the whole data set related to the entire project, please cite all the related papers.

RESUMEN

BACKGROUND: Hotspots of intraspecific genetic diversity represent invaluable resources for species to cope with environmental changes, and their identification is increasingly recognized as a major goal of conservation ecology research. However, even for iconic and endangered species, conservation strategies are often planned without thorough information on the geographic patterns of genetic variation. Here, we investigated the spatial patterns of genetic variation of the endangered Hermann's tortoise Testudo hermanni in the Italian Peninsula by genotyping 174 individuals at 7 microsatellite loci, with the aim to contribute to planning effective conservation strategies. RESULTS: Ordination-based and Bayesian clustering analyses consistently identified three main genetic clusters, one spread in the central and northern part of the peninsula, and two restricted to southern Italy and Sicily, respectively. The highest levels of genetic diversity were found in populations of the southern cluster and, in particular, at the northern edges of its distribution (He > 0.6, Ar > 2.8 ), that correspond to areas of putative secondary contact and admixture between distinct lineages. Our results clearly identify a hotspot of genetic diversity for the Hermann's tortoise in southern Italy. CONCLUSION: We inferred the evolutionary history and the spatial patterns of genetic variation of the Hermann's tortoise in the Italian Peninsula. We identified three main genetic clusters along the peninsula and a hotspot of intraspecific diversity in southern Italy. Our results underline the urgent need for conservation actions to warrant the long-term persistence of viable tortoise populations in this area. Furthrmore, these data add further evidence to the role of southern Italy as a biodiversity hotspot for temperate fauna, claiming for higher consideration of this area in large scale conservation programs.

RESUMEN

Testudo hermanni is included as near­threatened in the Red List of the International Union for Conservation of Nature, while T. hermanni hermanni is considered endangered in the Italian Red List. Appropriate management of smuggled or seized wild individuals is recommended before their reintroduction into the wild. Accordingly, a health monitoring study was carried out. During 2014­2016, 133 oral swabs and 121 cloacal swabs were collected from a total of approximately 180 free­ranging and rescued T. hermanni hermanni from eight different Italian regions to investigate the presence of DNA of Testudinid alphaherpesvirus (TeAHV), Chlamydia spp. and Mycoplasma spp. in the oral cavity, and Salmonella spp. isolates in the cloaca. Mycoplasma spp. was detected in 52 out of 87 (59.77%) of rescued and in 1 out of 46 free­ranging (2.17%) individuals; 33 out of 53 (62.26%) Mycoplasma spp. positive samples were typed as M. agassizii by PCR. Salmonella spp. was isolated from 45 out of 121 (37.19%) cloacal swabs, typed into 14 serovars, and characterized for complete antimicrobial susceptibility. A significantly different distribution of Salmonella spp. isolates was found in 2016 in comparison with 2014 and 2015, without any difference between free­ranging and rescued tortoises. All the tested tortoises were negative for TeAHV and Chlamydia spp. These results are considered a baseline information critical to monitor the dynamics of these microorganisms in free­ranging and rescued populations of T. h. hermanni, and to correctly approach the management of rescued animals and possible relocation programs.

RESUMEN

European plethodontid salamanders (genus Speleomantes; formerly Hydromantes) are a group of eight strictly protected amphibian species which are sensitive to human-induced environmental changes. Long-term monitoring is highly recommended to evaluate their status and to assess potential threats. Here we used two low-impact methodologies to build up a large dataset on two mainland Speleomantes species (S. strinatii and S. ambrosii), which represents an update to two previously published datasets, but also includes several new populations. Specifically, we provide a set of 851 high quality images and a table gathering stomach contents recognized from 560 salamanders. This dataset offers the opportunity to analyse phenotypic traits and stomach contents of eight populations belonging to two Speleomantes species. Furthermore, the data collection performed over different periods allows to expand the potential analyses through a wide temporal scale, allowing long-term studies.

RESUMEN

PURPOSE/OBJECTIVE: To describe the process of adapting the evidence-based Teen Online Problem Solving (TOPS) program, a telehealth problem-solving treatment addressing executive function and behavior regulation challenges in adolescents with traumatic brain injury, in Italy, New Zealand, and the United Kingdom. Research Method/Design: We describe the process of adapting and translating the TOPS program in 3 case studies with unique methods and samples. In Italy, 14 parents of adolescents with TBI participated in focus groups, and 2 adolescents with TBI and their parents and 2 physicians provided input on the resulting translation. In New Zealand, an independent Maori cultural advisor reviewed the content, and 6 adolescent-parent dyads and 2 health professionals completed the 10 modules independently over a five-week period to inform adaptation. In the United Kingdom, a team of neuropsychologists and a parent of an adolescent with ABI reviewed and adapted the content through successive iterations. RESULTS: In Italy, suggested changes included greater emphasis on nonverbal communication and clearer examples of inappropriate problem-solving responses. In New Zealand, parents and adolescents rated the program as acceptable and helpful. Suggestions included incorporating familiar Maori settings, integrating religion, and developing videos with New Zealand adolescents. In the United Kingdom, iterative refinements focused on adapting TOPS for other acquired brain injuries and reflecting cross-national differences (e.g., drinking age). CONCLUSIONS/IMPLICATIONS: These 3 case studies suggest that programs such as TOPS developed in 1 cultural context can be broadly acceptable in other contexts, with adaptations focusing on tailoring to reflect the unique cultural and linguistic setting.
