Exceeding the Ordinary: A Framework for Examining Teams Across the Extremeness Continuum and Its Impact on Future Research.

Work teams increasingly face unprecedented challenges in volatile, uncertain, complex, and often ambiguous environments. In response, team researchers have begun to focus more on teams whose work revolves around mitigating risks in these dynamic environments. Some highly insightful contributions to team research and organizational studies have originated from investigating teams that face unconventional or extreme events. Despite this increased attention to extreme teams, however, a comprehensive theoretical framework is missing. We introduce such a framework that envisions team extremeness as a continuous, multidimensional variable consisting of environmental extremeness (i.e., external team context) and task extremeness (i.e., internal team context). The proposed framework allows every team to be placed on the team extremeness continuum, bridging the gap between literature on extreme and more traditional teams. Furthermore, we present six propositions addressing how team extremeness may interact with team processes, emergent states, and outcomes using core variables for team effectiveness and the well-established input-mediator-output-input model to structure our theorizing. Finally, we outline some potential directions for future research by elaborating on temporal considerations (i.e., patterns and trajectories), measurement approaches, and consideration of multilevel relationships involving team extremeness. We hope that our theoretical framework and theorizing can create a path forward, stimulating future research within the organizational team literature to further examine the impact of team extremeness on team dynamics and effectiveness.

Air pollution and trajectories of adolescent conduct problems: the roles of ethnicity and racism; evidence from the DASH longitudinal study.

PURPOSE: No known UK empirical research has investigated prospective associations between ambient air pollutants and conduct problems in adolescence. Ethnic minority children are disproportionately exposed to structural factors that could moderate any observed relationships. This prospective study examined whether exposure to PM2.5 and NO2 concentrations is associated with conduct problems in adolescence, and whether racism or ethnicity moderate such associations. METHODS: Longitudinal associations between annual mean estimated PM2.5 and NO2 concentrations at the residential address and trajectories of conduct problems, and the potential influence of racism and ethnicity were examined school-based sample of 4775 participants (2002-2003 to 2005-2006) in London, using growth curve models. RESULTS: Overall, in the fully adjusted model, exposure to lower concentrations of PM2.5 and NO2 was associated with a decrease in conduct problems during adolescence, while exposure to higher concentrations was associated with a flattened trajectory of conduct symptoms. Racism amplified the effect of PM2.5 (ß = 0.05 (95% CI 0.01 to 0.10, p < 0.01)) on adolescent trajectories of conduct problems over time. At higher concentrations of PM2.5, there was a divergence of trajectories of adolescent conduct problems between ethnic minority groups, with White British and Black Caribbean adolescents experiencing an increase in conduct problems over time. CONCLUSION: These findings suggest that the intersections between air pollution, ethnicity, and racism are important influences on the development of conduct problems in adolescence.

To be or not to be an excellent football referee: different experts' viewpoints.

Football is central to the lives of countless individuals around the globe. While most of the attention of those passionate about the sport is focused on the players, football referees are often just as important in shaping the outcome of the games. Therefore, research is increasingly examining the role of referees. Even so, our understanding of the factors that create an excellent football referee is still scarce. Based on our analysis of the opinions of 24 football experts, we demonstrate the multidimensionality of excellence in the performance of football referees. From a Categorical Principal Components Analysis (CatPCA), we were able to pinpoint that football referee excellence is shaped by three distinct dimensions: individual preparation, game preparation and game management. Additionally, we were able to see if these perceptions were different from individuals "within" the game versus those "outside" the game. Namely, we used CatPCA to graphically display the main correlations between the latent dimensions of football refereeing performance and the "inside" and "outside" perspective of the game. The findings of our work contribute towards the knowledge of the factors that shape football referee excellence, while also highlighting areas in need of additional research attention.

Coherent Population Oscillation-Based Light Storage.

We theoretically study the propagation and storage of a classical field in a Λ-type atomic medium using coherent population oscillations (CPOs). We show that the propagation eigenmodes strongly relate to the different CPO modes of the system. Light storage in such modes is discussed by introducing a "populariton" quantity, a mixture of populations and field, by analogy to the dark state polariton used in the context of electromagnetically induced transparency light storage protocol. As experimentally shown, this memory relies on populations and is then-by contrast with usual Raman coherence optical storage protocols-robust to dephasing effects.

Phase-sensitive amplification via coherent population oscillations in metastable helium at room temperature.

In this Letter, we report our experimental results on phase-sensitive amplification (PSA) in a nondegenerate signal-idler configuration using ultranarrow coherent population oscillations in metastable helium at room temperature. We achieved a high PSA gain of nearly 7 with a bandwidth of 200 kHz by using the system at resonance in a single-pass scheme. Further, the measured minimum gain is close to the ideal value, showing that we have a nearly pure PSA. This is also confirmed from our phase-to-phase transfer curves measurements, illustrating that we have a nearly perfect squeezer, which is interesting for a variety of applications.

Boceprevir and telaprevir-based triple therapy for chronic hepatitis C: virological efficacy and impact on kidney function and model for end-stage liver disease score.

Triple therapy using telaprevir or boceprevir [hepatitis C virus (HCV)-NS3/NS4A protease inhibitors (PI)] in association with PEG-IFN/ribavirin has recently become the new standard of care (SOC) for treatment of HCV genotype 1 patients. Our objective was to assess the efficacy and tolerance of triple therapy in routine clinical practice. A total of 186 consecutive HCV patients initiating triple therapy were enrolled in a single centre study. Clinical, biological and virological data were collected at baseline and during follow-up as well as tolerance and side effect details. Among 186 HCV patients initiating triple therapy, 69% received telaprevir and 31% boceprevir. Sixty-one per cent of patients had cirrhosis. The overall extended rapid virological response (eRVR) rate and sustained virological response (SVR) rate were 57.0% and 59.7%, respectively. IL28B CC phenotype was associated with increased probability of achieving eRVR and SVR, whereas previous non-response was associated with low eRVR and SVR rates. The SVR rate increased from 30.8% in previously non-responders to 59.1% in partial non-responders and 75% in relapsers. SVR rate in naive patients was 62.5%. Glomerular filtration rate assessed by MDRD after 12 weeks of therapy was significantly reduced for both PI (P < 0.001). The model for end-stage liver disease (MELD) score was significantly increased at W12 for telaprevir (P = 0.008) and at W24 for boceprevir (P = 0.027). PI-based triple therapy leads to high rates of virological response even in previously non-responder patients. Renal function after triple therapy is impaired as well as MELD score in all patients. Cautious clinical monitoring should focus not only on haematological and dermatological side effects but also on renal function.

Evolution of glomerular filtration rate in HIV-infected, HIV-HBV-coinfected and HBV-infected patients receiving tenofovir disoproxil fumarate.

We aimed to compare the evolution of estimated glomerular filtration rate (eGFR) in HIV-, HIV-HBV- and HBV-infected patients treated with tenofovir disoproxil fumarate (TDF). Three groups of patients receiving TDF > 12 months were recruited: 194 HIV-infected patients, 85 HIV-HBV-coinfected patients and 50 HBV-infected patients. eGFR was estimated using the Modification of the Diet in Renal Disease (MDRD) equation. Multivariate regression models were constructed to estimate factors associated with eGFR decrease from baseline. A total of 329 patients were studied. Median follow-up was 2.7 years. Median eGFR decrease was -4.9 (-16.6 to +7.2) mL/min/1.73 m(2) . After multivariate stepwise regression analysis, age (P = 0.0002), non-African origin (P < 0.0001), baseline eGFR (P < 0.0001) and TDF duration (P = 0.02) were associated with eGFR decrease in the whole population, while hypertension, diabetes and type of infection were not. Age (P < 0.0001), non-African origin (P = 0.0004), baseline eGFR (P < 0.0001) and TDF duration (P = 0.007) remained associated with eGFR decline in HIV and HIV-HBV-infected patients, while other variables including HIV risk factor, CDC stage, CD4 and HIV-RNA levels were not. Age (P = 0.03), non-African origin (P = 0.004), baseline eGFR (P < 0.0001) and baseline HBV-DNA > 2000 IU/mL (P = 0.04) were associated with eGFR decline in HBV and HIV-HBV-infected patients, while other variables including HBV risk factor and fibrosis stage were not. Estimated glomerular filtration rate decline under TDF therapy appears mainly associated with older age, non-African origin, higher baseline eGFR and longer TDF administration but not with the type of viral infection. Regular follow-up of renal function, especially tubular function is recommended during TDF therapy.

Perceptions of healthy eating and physical activity in an ethnically diverse sample of young children and their parents: the DEAL prevention of obesity study.

BACKGROUND: Ethnicity is a consistent correlate of obesity; however, little is known about the perceptions and beliefs that may influence engagement with obesity prevention programmes among ethnic minority children. Barriers to (and facilitators of) healthy lifestyles were examined in the qualitative arm of the London (UK) DiEt and Active Living (DEAL) study. METHODS: Children aged 8-13 years and their parents, from diverse ethnic groups, were recruited through schools and through places of worship. Thirteen focus group sessions were held with 70 children (n = 39 girls) and eight focus groups and five interviews with 43 parents (n = 34 mothers). RESULTS: Across ethnic groups, dislike of school meals, lack of knowledge of physical activity guidelines for children and negativity towards physical education at school among girls, potentially hindered healthy living. Issues relating to families' wider neighbourhoods (e.g. fast food outlets; lack of safety) illustrated child and parental concerns that environments could thwart intentions for healthy eating and activity. By contrast, there was general awareness of key dietary messages and an emphasis on dietary variety and balance. For ethnic minorities, places of worship were key focal points for social support. Discourse around the retention of traditional practices, family roles and responsibilities, and religion highlighted both potential facilitators (e.g. the importance of family meals) and barriers (reliance on convenience stores for traditional foods). Socio-economic circumstances intersected with key themes, within and between ethnic groups. CONCLUSIONS: Several barriers to (and facilitators of) healthy lifestyles were common across ethnic groups. Diversity of cultural frameworks not only were more nuanced, but also shaped lifestyles for minority children.

Associations between air pollutants and blood pressure in an ethnically diverse cohort of adolescents in London, England.

Longitudinal evidence on the association between air pollution and blood pressure (BP) in adolescence is scarce. We explored this association in an ethnically diverse cohort of schoolchildren. Sex-stratified, linear random-effects modelling was used to examine how modelled residential exposure to annual average nitrogen dioxide (NO2), particulate matter (PM2.5, PM10) and ozone (O3), measures in µg/m3, associated with blood pressure. Estimates were based on 3,284 adolescents; 80% from ethnic minority groups, recruited from 51 schools, and followed up from 11-13 to 14-16 years old. Ethnic minorities were exposed to higher modelled annual average concentrations of pollution at residential postcode level than their White UK peers. A two-pollutant model (NO2 & PM2.5), adjusted for ethnicity, age, anthropometry, and pubertal status, highlighted associations with systolic, but not diastolic BP. A µg/m3 increase in NO2 was associated with a 0.30 mmHg (95% CI 0.18 to 0.40) decrease in systolic BP for girls and 0.19 mmHg (95% CI 0.07 to 0.31) decrease in systolic BP for boys. In contrast, a 1 µg/m3 increase in PM2.5 was associated with 1.34 mmHg (95% CI 0.85 to 1.82) increase in systolic BP for girls and 0.57 mmHg (95% CI 0.04 to 1.03) increase in systolic BP for boys. Associations did not vary by ethnicity, body size or socio-economic advantage. Associations were robust to adjustments for noise levels and lung function at 11-13 years. In summary, higher ambient levels of NO2 were associated with lower and PM2.5 with higher systolic BP across adolescence, with stronger associations for girls.

Resilience in organization-related research: An integrative conceptual review across disciplines and levels of analysis.

Resilience is a topic of growing interest in the literature focused on organizations. There is an extensive research on resilience but it is embedded in a variety of disconnected literatures that have developed in different research fields, involving varying levels of analysis and different subconstructs. This has resulted in a general confusion surrounding the concept of resilience and its relationship to similar constructs. In this paper, we synthesize this fragmented literature to better understand organization-related resilience and set the stage for future work in this area. First, based on a bibliographic coupling analysis of 1,667 articles, we identify 10 historical clusters that have shaped this domain and highlight how these clusters have developed over time. Second, drawing on recommendations for how research can develop high-quality concept definitions, we analyze subconstructs, conceptual definitions, and measures applied in this domain. Third, we distinguish resilience from related constructs. Overall, our synthesis revealed that resilience is an important and distinct concept in organization-related research. In spite of this, the field has suffered from the presence of a jingle-jangle fallacy, which means that existing conceptualizations of resilience assign different meanings to this label, while at the same time various subconstructs exist. Thus, fourth, we develop a framework integrating the broad literature of organization-related resilience into three distinct themes of research that offer different insights into how entities across levels deal with adversity. In an attempt to provide guidance for research that builds upon this review, we conclude with an agenda for future investigations. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

What Do We Really Know About Crew Resource Management in Healthcare?: An Umbrella Review on Crew Resource Management and Its Effectiveness.

OBJECTIVE: The aim of this article was to present an overview of the crew resource management (CRM) literature in healthcare. The first aim was to conduct an umbrella review on CRM literature reviews. The second aim was to conduct a new literature review that aims to address the gaps that were identified through the umbrella review. METHODS: First, we conducted an umbrella review to identify all reviews that have focused on CRM within the healthcare context. This step resulted in 16 literature reviews. Second, we conducted a comprehensive literature review that resulted in 106 articles. RESULTS: The 16 literature reviews showed a high level of heterogeneity, which resulted in discussing 3 ambiguities: definition, outcome, and information ambiguity. As a result of these ambiguities, a new comprehensive review of the CRM literature was conducted. This review showed that CRM seems to have a positive effect on outcomes at Kirkpatrick's level 1, 2, and 3. In contrast, whether CRM has a positive effect on level 4 outcomes and how level 4 should be measured remains undetermined. Recommendations on how to implement and embed CRM training into an organization to achieve the desired effects have not been adequately considered. CONCLUSIONS: The extensive nature of this review demonstrates the popularity of CRM in healthcare, but at the same time, it highlights that research tends to be situated within certain settings, focuses on particular outcomes, and has failed to address the full scope of CRM as a team intervention and a management concept.

Team leader coaching intervention: An investigation of the impact on team processes and performance within a surgical context.

We examined the impact of a team leader coaching intervention on episodic team processes (transition, action, interpersonal) and subsequent team performance outcomes within a surgical context. Specifically, we tested whether coaching team leaders (i.e., surgeons) on promoting effective teamwork facilitates team processes and two important outcomes-delays and distractions. Team processes were indexed using detailed observational protocols by subject-matter experts before and during surgeries. We employed an interrupted time series design whereby half of our participants received coaching midway through the longitudinal period and the remaining served as a quasi-control group. Team processes and outcomes were collected from multiple surgeries, per surgeon, both before and after the coaching intervention (N = 223 surgeries total). Results from a multilevel mixed-model (treatment vs. control, over time) structural equation model suggest that teams where the surgeon (team leader) received the coaching intervention exhibited higher-quality team transition processes. Transition processes related positively to subsequent action and interpersonal processes, which in turn yielded improvements in two different surgical team performance outcomes. Theoretical and applied implications are discussed. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

Perceived parenting and psychological well-being in UK ethnic minority adolescents.

BACKGROUND: Warm, caring parenting with appropriate supervision and control is considered to contribute to the best mental health outcomes for young people. The extent to which this view on 'optimal' parenting and health applies across ethnicities, warrants further attention. We examined associations between perceived parental care and parental control and psychological well-being among ethnically diverse UK adolescents. METHODS: In 2003 a sample of 4349 pupils aged 11-13 years completed eight self-reported parenting items. These items were used to derive the parental care and control scores. Higher score represents greater care and control, respectively. Psychological well-being was based on total psychological difficulties score from Goodman's Strengths and Difficulties Questionnaire, increasing score corresponding to increasing difficulties. RESULTS: All minority pupils had lower mean care and higher mean control scores compared with Whites. In models stratified by ethnicity, increasing parental care was associated with lower psychological difficulties score (better mental health) and increasing parental control with higher psychological difficulties score within each ethnic group, compared with reference categories. The difference in psychological difficulties between the highest and lowest tertiles of parental care, adjusted for age, sex, family type and socio-economic circumstances, was: White UK =-2.92 (95% confidence interval -3.72, -2.12); Black Caribbean =-2.08 (-2.94, -1.22); Nigerian/Ghanaian =-2.60 (-3.58, -1.62); Other African =-3.12 (-4.24, -2.01); Indian =-2.77 (-4.09, -1.45); Pakistani/ Bangladeshi =-3.15 (-4.27, -2.03). Between ethnic groups (i.e. in models including ethnicity), relatively better mental health of minority groups compared with Whites was apparent even in categories of low care and low autonomy. Adjusting for parenting scores, however, did not fully account for the protective effect of minority ethnicity. CONCLUSIONS: Perceived quality of parenting is a correlate of psychological difficulties score for all ethnic groups despite differences in reporting. It is therefore likely that programmes supporting parenting will be effective regardless of ethnicity.

Mines in the End Zone: Are there Downsides to Team Performance?

Research on teams in organizations tends to focus on understanding the causes of team performance with a focus on how to enjoy the benefits of team success and avoid the negative consequences of team failure. This paper instead asks the question, 'what are some of the negative consequences of team success?' A review of the literature on teams is augmented with research from cognitive science, sociology, occupational psychology, and psychology to explore the potential negative long-term consequences of teamwork success. The general topics of groupthink, overconfidence bias, regression to the mean, role overload, and strategy calcification are reviewed while discussing the implications for future research streams and practical team management.

Development of the Referee Shared Mental Models Measure (RSMMM).

The concept of shared mental models refers to the shared understanding among team members about how they should behave in different situations. This article aimed to develop a new shared mental model measure, specifically designed for the refereeing context. A cross-sectional study was conducted with three samples: national and regional football referees (n = 133), national football referees and assistant referees and national futsal referees (n = 277), and national futsal referees (n = 60). The proposed version of the Referee Shared Mental Models Measure (RSMMM) has 13 items that are reflected on a single factor structure. The RSMMM presented good validity evidence both based on the internal structure and based on relations to other variables (presenting positive associations with team work engagement, team adaptive performance, and team effectiveness). Such promising psychometric properties point to an optimistic outlook regarding its use to measure shared mental models in futsal and football referee teams.

Informal field-based learning and work design.

U.S. organizations continue to invest most of their learning budgets in formal training and development programs despite estimates that the majority of learning in the workplace happens informally. In this study we focus on informal field-based learning (IFBL), which represents individuals engaging in self-directed, intentional, and field-based development of their knowledge and skills. We build on the informal learning literature to advance a cross-level model of individual and job-level characteristics as influences on IFBL and subsequent changes in job performance. We tested our model using a sample of 378 health care employees who occupied 47 different jobs. The results showed promotion-focused individuals more readily engaged in IFBL, as moderated by job time pressures. Moreover, engaging in IFBL behaviors positively related to performance improvements in jobs that require greater updating and use of relevant information, as well as in jobs with relatively low decision making and problem-solving requirements. Exploratory subdimensional analyses revealed some interesting countervailing relationships between the feedback-seeking and vicarious-learning elements of IFBL. Results are discussed in terms of contingency relationships associated with IFBL behaviors and different job types, as well as theoretical and practical implications.

Overweight, obesity and high blood pressure in an ethnically diverse sample of adolescents in Britain: the Medical Research Council DASH study.

OBJECTIVES: To examine the impact of overweight on mean, high normal and high blood pressure in early adolescence, and how this relates to ethnicity and socio-economic status. DESIGN: Cross-sectional study with anthropometric and blood pressure measurements. SETTING: A total of 51 secondary schools in London. SAMPLE: A total of 6407 subjects, 11-13 years of age, including 1204 White UK, 698 Other Whites, 911 Black Caribbeans, 1065 black Africans, 477 Indians and 611 Pakistanis/Bangladeshis. MAIN OUTCOME MEASURES: Mean, high normal (gender, age and height-percentile-specific 90-94th percentile) and high (>/=95th percentile) blood pressure. RESULTS: Based on the International Obesity Task Force age-specific thresholds, 19% of boys and 23% of girls were overweight, and 8% of each were obese. Overweight and obesity were associated with large increases in the prevalence of high normal and high blood pressures compared with those not overweight. The increases in the prevalence of high systolic pressure associated with overweight were as follows: boys, odds ratio 2.50 (95% confidence intervals 1.73-3.60) and girls 3.39 (2.36-4.85). Corresponding figures for obesity were: boys 4.31 (2.82-6.61) and girls 5.68 (3.61-8.95). Compared with their White British peers, obesity was associated with larger effects on blood pressure measures only among Indians, despite more overweight and obesity among black Caribbean girls and overweight among Black African girls. The effect of socio-economic status was inconsistent. CONCLUSIONS: The tendency to high blood pressure among adult Black African origin populations was not evident at these ages. These results suggest that the rise in obesity in adolescence portends a rise in early onset of cardiovascular disease across ethnic groups, with Indians appearing to be more vulnerable.

DEVELOPING, SUSTAINING, AND MAXIMIZING TEAM EFFECTIVENESS: AN INTEGRATIVE, DYNAMIC PERSPECTIVE OF TEAM DEVELOPMENT INTERVENTIONS.

Organizations regularly make significant investments to ensure their teams will thrive, through interventions intended to support their effectiveness. Such team development interventions (TDIs) have demonstrated their value from both a practical and empirical view, through enabling teams to minimize errors and maximize expertise and thereby advance organizational gains. Yet, on closer examination, the current state of the TDI literature appears so piecemeal that the robustness of extant scientific evidence is often lost. Accordingly, we seek to provide a more cohesive and dynamic integration of the TDI literature, evolving thinking about TDIs toward a system of interventions that can be optimized. Drawing on the existing theoretical and empirical literatures, we first broadly define TDIs. We then offer an in-depth look at the most common types of TDIs, in terms of summarizing the state of the science surrounding each TDI. Based on this review, we distinguish features that make for an effective TDI. We then advance a more integrative framework that seeks to highlight certain interventions that are best served for addressing certain issues within a team. In conclusion, we promote a call for evolving this robust yet disjointed TDI literature into a more holistic, dynamic, and intentional action science with clear empirical as well as practical guidance and direction.

A cross-level investigation of informal field-based learning and performance improvements.

Organizations often operate in complex and dynamic environments which place a premium on employees' ongoing learning and acquisition of new competencies. Additionally, the majority of learning in organizations does not take place in formal training settings, but we know relatively little about how informal field-based learning (IFBL) behaviors relate to changes in job performance. In this study, we first clarified the construct of IFBL as a subset of informal learning. Second, on the basis of this clarified construct definition, we developed a measure of IFBL behaviors and demonstrated its psychometric properties using (a) a sample of subject matter experts who made item content validity judgments and (b) both an Amazon Mechanical Turk sample (N = 400) and a sample of 1,707 healthcare employees. Third, we advanced a grounded theory of IFBL in healthcare, and related it to individuals' regulatory foci and contextual moderators of IFBL behaviors-job performance relationships using a cross-level design and lagged nonmethod bound measures. Specifically, using a sample of 407 healthcare workers from 49 hospital units, our results suggested that promotion-focused individuals, especially in well-staffed units, readily engage in IFBL behaviors. Additionally, we found that the IFBL-changes in job performance relationship was strengthened to the extent that individuals worked in units with relatively nonpunitive climates. Interestingly, staffing levels had a weakening moderating effect on the positive IFBL-performance improvements relationship. Detailed follow-up analyses revealed that the peculiar effect was attributable to differential relationships from IFBL subdimensions. Implications for future theory building, research, and practice are discussed. (PsycINFO Database Record

Age-related changes in pain sensitivity in healthy humans: A systematic review with meta-analysis.

Literature suggests that pain perception diminishes in old age. The most recent review used search strategies conducted over a decade ago and concluded that study findings were equivocal. The aim of this systematic review, with meta-analysis, was to determine age-related changes in pain sensitivity in healthy pain-free adults, children and adolescents. A search of PubMed, Science Direct, and PsycINFO identified studies that compared pain sensitivity response to noxious stimuli at different time points in the lifespan of healthy individuals. Selected studies were assessed for methodological quality and data pooled and meta-analysed. Publication bias was tested using Funnel plots. Twelve studies were included in the review (study sample sizes 30-244 participants). Seven of nine studies found statistically significant differences in pain sensitivity response between old (mean ± SD 62.2 ± 3.4 to 79 ± 4 years) and younger adults (22 ± 1.5 to 39.1 ± 8.8 years), but the direction of change was inconsistent. Meta-analysis found that pressure pain threshold was lower in old adults compared with younger adults (p = 0.018, I2  = 60.970%). There were no differences in contact heat pain thresholds between old and younger adults (p = 0.0001, I2  = 90.23%). Three studies found that younger children (6-8.12 years) were more sensitive to noxious stimuli than older children (9-14 years). Methodological quality of studies was high, with a low risk of publication bias. There was substantial statistical and methodological heterogeneity. There is tentative evidence that pressure pain threshold was lower in old adults compared with younger adults, with no differences in heat pain thresholds. Further studies are needed. SIGNIFICANCE: There is tentative evidence that old adults may be more sensitive to mechanically-evoked pain but not heat-evoked pain than young adults. There is a need for further studies on age-related changes in pain perception.
