Background: Oral health is thought to be an essential part of general healthiness. Poor oral hygiene can significantly affect the quality of life which may initiate deterioration of overall health. Aim: To find out reasons or misapprehensions that stop the dental patients from getting scaling procedure. Methodology: This questionnaire-based cross-sectional study was conducted in tertiary care dental hospital of Multan from November 2019 to February 2020. Three hundred and six patients filled a questionnaire designed and tested for this study. The ethical approval (MDC-1290) was taken from the Dental Hospital, informed consent was obtained from the participants in the study. Results: Out of 306 participants, 49% participants were males and 51%were females. 24% percent participants reported that we have more than one reasons for avoidance of scaling procedure. Among other fears top-most were 16% participants believed that scaling is a painful procedure and 13% said that scaling increases the mobility of teeth. Conclusion: Now-a-days misapprehensions or fear regarding scaling has been reduced because of self-awareness programs started by social media activists Keywords: Anxiety, Fear, Mobility, Myth, Scaling, Pain, Sensitivity

Quantum phase transitions in non-Hermitian [formula omitted]-symmetric transverse-field Ising spin chains

We present a theoretical study of quantum phases and quantum phase transitions occurring in non-Hermitian PT-symmetric superconducting qubits chains described by a transverse-field Ising spin model. A non-Hermitian part of the Hamiltonian is implemented via imaginary staggered longitudinal magnetic field, which corresponds to a local staggered gain and loss terms. By making use of a direct numerical diagonalization of the Hamiltonian for spin chains of a finite size N, we explore the dependencies of the energy spectrum, including the energy difference between the first excited and the ground states, the spatial correlation function of local polarization (z-component of local magnetization) on the adjacent spins interaction strength J and the local gain (loss) parameter γ. A scaling procedure for the correlation length ξ allows us to establish a complete quantum phase diagram of the system. We obtain two quantum phases for J<0, namely, PT-symmetry broken antiferromagnetic state and PT-symmetry preserved paramagnetic state, and the quantum phase transition line between them is the line of exception points. For J>0 the PT-symmetry of the ground state is retained in a whole region of parameter space of J and γ, and a system shows two intriguing quantum phase transitions between ferromagnetic and paramagnetic states for a fixed parameter γ>1. We also provide the qualitative quantum phase diagram γ−J derived in the framework of the Bethe–Peierls approximation that is in a good accord with numerically obtained results.

Application of dissipative particle dynamics to interfacial systems: Parameterization and scaling

Dissipative Particle Dynamics (DPD) is a stochastic particle model that is able to simulate larger systems over longer time scales than atomistic modeling approaches by including the concept of coarse-graining. Whether standard DPD can cover the whole mesoscale by changing the level of coarse-graining is still an open issue. A scaling scheme originally developed by Füchslin et al. (2009) was here applied to interfacial systems as one of the most successful uses of the classical DPD method. In particular, equilibrium properties such as the interfacial tension were analyzed at different levels of coarse-graining for planar oil–water interfaces with and without surfactant. A scaling factor for the interfacial tension was found due to the combined effect of the scaling scheme and the coarse-graining parameterization. Although the level of molecular description was largely decreased, promising results showed that it is possible to conserve the interfacial tension trend at increasing surfactant concentrations, remarkably reducing modeling complexity. The same approach was also employed to simulate a droplet configuration. Both planar and droplet conformations were maintained, showing that typical domain formations of multi-component systems can be performed in DPD by means of the scaling procedure. Therefore, we explored the possibility of describing oil–water and oil–water–surfactant systems in standard DPD using a scaling scheme with the aim of highlighting its advantages and limitations.

Design of a Test Section for the Experimental Investigation of the WCLL Manifold Hydraulic Features

A scaled-down test section representative of an Outboard Segment manifold of the Water-Cooled Lithium Lead Breeding Blanket for the European DEMO has been designed for installation and test in a high- mass flow branch of the W-HYDRA facility, under construction at the premises of ENEA Brasimone Research Center. The test section should confirm the flow repartition recently computed in the different breeding units on the full-scale manifold, validating at the same time the computational tools used for the design and analysis. The detailed objectives and requirements of the test section, as well as the scaling rationale and procedure adopted for its design, are presented in the paper. The final design of the test section is discussed. The preliminary analyses of the developed design are also presented and show that it is compliant with the initial objectives.

A Correlated Network Scale-Up Model: Finding the Connection Between Subpopulations

Aggregated Relational Data (ARD), formed from “How many X’s do you know?” questions, is a powerful tool for learning important network characteristics with incomplete network data. Compared to traditional survey methods, ARD is attractive as it does not require a sample from the target population and does not ask respondents to self-reveal their own status. This is helpful for studying hard-to-reach populations like female sex workers who may be hesitant to reveal their status. From December 2008 to February 2009, the Kiev International Institute of Sociology (KIIS) collected ARD from 10,866 respondents to estimate the size of HIV-related groups in Ukraine. To analyze this data, we propose a new ARD model which incorporates respondent and group covariates in a regression framework and includes a bias term that is correlated between groups. We also introduce a new scaling procedure using the correlation structure to further reduce biases. The resulting size estimates of those most-at-risk of HIV infection can improve the HIV response efficiency in Ukraine. Additionally, the proposed model allows us to better understand two network features without the full network data: (a) What characteristics affect who respondents know, and (b) How is knowing someone from one group related to knowing people from other groups. These features can allow researchers to better recruit marginalized individuals into the prevention and treatment programs. Our proposed model and several existing NSUM models are implemented in the networkscaleup R package. Supplementary materials for this article are available online.

Time continuous two-source energy-water balance modelling of heterogeneous crops: FEST-2-EWB

An accurate knowledge of the water and energy exchanges in the soil-crop-atmosphere system is critical for a precise and aware control of all agricultural operations, from field management to irrigation and harvest. This concern is more complex to address in heterogeneous systems, with the presence of bare soil or simple grass in between the main crop. In this work, a two-source energy-water balance model is developed, joining the advantages of the single-source FEST-EWB model (internal computation of surface temperature and time-continuous modelling) and those of two-source approaches (employing two surface temperatures to accurately characterize the intra-pixel heterogeneity). In order to validate the model results, a laboratory experiment has been designed over a lysimeter, with the target of obtaining partitioned estimates of Evaporation and Transpiration over a heterogeneous grass crop. These partitioned fluxes were supported by a safe error margin in the scaling procedure (less than ± 1 mm/d). The FEST-EWB and FEST-2-EWB models were first calibrated using surface temperature obtained from thermal camera observations (with roughly 1.7°C of average bias). Then, they were validated against the partitioned estimated. The single-source modelling showed a consistent overestimation of the estimated Transpiration, by an amount roughly 20% of the average irrigation event. On the other hand, the two-source model shows much lower (6%) errors, portraying more accurately the Transpired water volume. Such an improvement in crop water consumption estimation can provide a successful reference to optimize the use of the irrigation water resource, with consistent water savings.

An Aeroacoustic Study of Full-Scale and Small-Scale Generic Landing Gear Models with Identical Geometry

The paper reports on the results of acoustic measurements of full-scale and small-scale generic landing gear models, which have identical geometry and differ only by their scales. The large-scale landing gear models were simplified and lack small geometric details, which for the first time allows their results to be directly compared with those for the small-scale models of the same geometry. It is shown that after application of the scaling procedure to their noise spectra, the normalized results for broadband noise of the landing gear models of different scales are in good agreement with each other. This result seems to support the feasibility of developing technologies for low-frequency noise reduction of landing gears based on small-scale tests and allowing refinement of semi-empirical models of noise prediction for different landing gear elements.

Demystifying the eighth lean waste: a knowledge waste scale

PurposeSince few studies have explored and advanced on the development of measures of knowledge waste, the purpose of this paper is to develop and validate a scale for measuring the waste of knowledge.Design/methodology/approachA research was carried out in Higher Education Institutions (HEIs) divided into five distinct stages, three qualitative and two quantitative. For the quantitative steps, a sample of 223 responses was obtained for the exploratory part and another sample of 614 responses for the confirmatory part of the study. Data analysis procedures involved Exploratory and Confirmatory Factor Analysis to test and validate the proposed scale.FindingsA fifteen-item scale divided into four constructs was obtained after refinement of the proposed scale and validation procedures (convergent and discriminant validity). The scale also has satisfactory levels of reliability.Research limitations/implicationsThe resulting scale was validated in a single institutional culture environment (HEIs in Southern Brazil). So it still should be tested in different organizational contexts and cross-culturally in different countries. The scale may be useful for decision-making improvement about knowledge management and waste reduction.Practical implicationsA scale with a practical and quick application is provided. Additionally, a classification of the waste of knowledge level was developed and it could be easily applied in different sectors or organizations.Originality/valueThe literature on waste of knowledge is limited and often confused with knowledge loss. This study provides a clear distinction between these topics, and it advances on the explanation and definition of knowledge waste. Also, it is the first study to offer a scale to measure the elements of knowledge waste.

Mixed-Alkali Effect and Correlation to Glass Structure in Ionically Conductive P2O5-Al2O3-Na2O-K2O Glass System

In this study, the nature of the electrical transport and structural changes resulting from the systematic substitution of Al2O3 with K2O in 40P2O5-(25−x)Al2O3-35Na2O-xK2O, where x = 5.0, 7.5, 10.0, 12.5, and 15.0 mol% (PANxK), is investigated. The impact of the changes in glass structure and its correlation to electrical properties is presented. The mixed alkali effect (MAE) is observed due to the presence of two different alkali oxides, resulting in a non-monotonic trend in the studied glass properties. The infrared spectra show the shift and diminishing of the bands related to the P–O–P/P–O–Al bridges with increasing K2O content and changes in bands related to depolymerization of the glass network, which is confirmed by the trend of the Tg values. The minimum value of DC conductivity is obtained for glass with x = 12.5 mol%. With the overall increase in alkali content, the number of non-bridging oxygens increases, also affecting the conductivity values. Frequency-dependent conductivity spectra analyzed by Summerfield, Baranovskii-Cordes and Sidebottom scaling procedures revealed interesting features and signature of the MAE in the short-range dynamics of the potassium and sodium ions, both for individual glass composition and glass series as a whole. This study showed the impact of MAE and local glass structure on the electrical features and the prevailing of one effect over the other as a function of the glass composition. MAE dominates in a wider range, but with the significant increase in alkali content, MAE is consequently overpowered.

Nonlinear coupled dynamics of suspended cables due to crossover points shifting and symmetry breaking

This work deals with the nonlinear coupled dynamics of suspended cables considering two unavoidable factors: temperature changes and damaged situations. Particularly, the thermal-induced crossover shifting and damage-induced symmetry-breaking are considered and investigated. A kinematically condensed mathematical model with thermal and damage effects simultaneously is employed for the transverse displacements. A weighted-residual technique based on the Galerkin method is adopted to reduce the continuous model from the partial differential equations to ordinary ones. Following the multiple scales procedure for a weakly nonlinear system, both the polar and Cartesian forms of modulation equations are achieved. Based on the eigenvalue analyses, natural frequencies and mode shapes with thermal and damage effects are presented, and the crossover and veering points between natural frequencies are observed. Resonant behaviors of suspended cables after crossover points shifting and symmetry-breaking are revealed by using the numerical continuation and bifurcation analysis. Quantitative and qualitative differences in dynamic behaviors induced by temperature and damage factors are exhibited and illustrated through some parametric studies. Direct numerical integration solutions are adopted to confirm the perturbation ones, and a good agreement is observed.

Evaluation of Effects of Scaling with and without Polishing on Oral Hygiene Clinical Parameters – A Concurrent Parallel Randomized Trial

Introduction: Good oral health is a crucial indicator of overall well-being. Oral hygiene maintenance and care is the practice of keeping the oral cavity clean and disease free. The main objective of this study was to evaluate the effects of scaling and polishing on oral hygiene clinical parameters at different intervals. Materials and Methods: A concurrent parallel randomized trial was carried out among 60 college students in the Namakkal district. Subjects were randomly assigned into two groups, the scaling followed by the polishing group and the scaling without polishing group. This was a three-point assessment (baseline, 2nd week, and 3rd week) for plaque, gingival, and marginal line calculus index scores. Data were analyzed using parametric tests: independent t-test and repeated measures ANOVA. Results: A statistically significant difference was found for all three clinical parameters at the final 3rd-week follow-up between the two groups. Between the intervals, both the groups had a significant difference (P &lt; 0.05) for plaque, gingival, and calculus index. Conclusion: Scaling followed by polishing had better results when compared to scaling without polishing. Microlocal irregularities, caused by scaling procedures, might be the cause for further accumulation of debris which can be reduced by polishing procedures.

Foam placement for soil remediation: scaling foam flow models in heterogeneous porous media for a better improvement of sweep efficiency

If injected with a large gas fraction, foam reduces mobility more in high-permeability layers and diverts flow to low-permeability layers. Here is a qualitative statement that has been claimed many times in many works related to environmental remediation and oil recovery. It is so true and relevant for foam flow in porous media and yet so little quantified and even less exploited in Darcy-scale numerical simulation. After briefly reviewing opportunities and challenges related to the use of foams in porous media and its Darcy-scale implicit-texture and population-balance modelling, we make a detour out of the strict framework of mathematical models by revisiting with a fresh eye the physics of foams on the large scale of heterogeneous natural porous media in terms of scaling laws. Specifically, it has been recently shown experimentally and theoretically that foam mobility reduction scales approximately as the square root of rock permeability within the framework of Darcy-type implicit-texture foam flow models [Douarche et al. (2020) Scaling foam flow models in heterogeneous reservoirs for a better improvement of sweep efficiency (Paper ThB04), in:17th European Conference of the Mathematics of Oil Recovery (ECMOR), Edinburgh, Scotland, 14–17 September; Gassara et al. (2020) Trans. Porous Media 131, 1, 193–221]. This also appears to hold for population-balance models under the local steady state assumption. This quantitative scaling law for the effect of permeability on foam properties was inferred from an analogy between foam flow in porous media and foam flow in capillary tubes and was found consistent with the modelling of available experimental data. We demonstrate by varying the permeability contrast and anisotropy of a stack of porous layers how foam regulates the flow and leads to flow diversion from high- to low-permeability layers. The threshold in permeability heterogeneity for which such a foam-driven diversion becomes effective is quantified through a sensitivity study accounting for foam injection type, permeability heterogeneity and anisotropy, heterogeneity structure, and scaling procedure. The simulations carried out clearly indicate that ignoring mobility reduction dependence on permeability in the foam process assessment of heterogeneous formations leads to an underestimation of mobility reduction benefits to improve flow conformance. The question of cores selection, as this rock-typing strategy in relation to the porous medium characterization may guide a smart and optimal design of pre-feasibility laboratory campaign for foam evaluation, and the generalization of the findings to multi-facies geological formations are also discussed. As such, the use of physical foam mobility reduction scaling law is highly recommended for foam process evaluation.

A Comparison of Two Macroinvertebrate Multi-Plate Sampling Methods to Inform Great Lakes Monitoring and Remediation Efforts.

Hester-Dendy (HD) multi-plate samplers have been widely used by state and federal government agencies for bioassessment of water quality through use of macroinvertebrate community data. To help guide remediation and restoration efforts at the Niagara River Great Lakes Area of Concern site, a multi-agency study was conducted in 2014 to assess the contribution of seven major urban tributaries on the US side of the river toward the impairment of the Niagara River. As part of this study, macroinvertebrate communities were sampled using two co-located versions of HD samplers: one version used by the New York State Department of Environmental Conservation (NYSDEC) and another by the US Environmental Protection Agency Office of Research and Development. Samplers were deployed in tributaries in highly developed watersheds with high percent impervious surface. The two sampling methods varied in terms of number and size of plates, between-plate spacing, and deployment method. Comparison of the similarity/grouping of communities with multivariate ordination techniques, Nonmetric Multidimensional Scaling and Multi-Response Permutation Procedure, showed that both methods were able to detect differences in communities at stations, despite some grouping by month and method. The indices and metrics derived from the two HD methods were found to give comparable but not identical assessments of water quality. Despite their differences, the methods were robust with respect to water quality categories derived from indices used nationally (HBI) and by NY state (BAP). For the common richness metrics, total taxa and EPT richness, there was no statistical difference between means from 3 samplings. Some metrics, especially percent tolerant collector-gatherer individuals, did show significant differences at certain stations. Indicator Species Analysis showed some taxa associated with each method. The observed community differences were thought mostly due to the difference in sampler deployment position.

Role of Medicinal Herbs in Periodontal Therapy: A Systematic Review.

The use of medicinal herbs to prevent gingival and periodontal diseases has become increasingly popular due to their anti-inflammatory and antioxidant properties. This systematic review aims to provide the current literature to validate the traditional use of medicinal herbs in the management of gingival and periodontal diseases. An online literature search was conducted to identify research papers published from 2010 to 2022 in three major scientific databases, PubMed, Scopus, and Web of Science, in June 2022. Original research studies, case reports, and systematic reviews on medicinal plants' application in oral health care were selected to be included in this systematic review. Only high-quality articles identified in the quality assessment were included for evidence synthesis. Initial keyword research yielded 726 free-text articles published between 2010 and 2022. Of these, 14 articles (8 research papers and 6 reviews) were included for evidence synthesis. The review's findings indicate that the antibacterial property of medicinal plants is due to their alkaline nature and prevents plaque and calculus formation by maintaining acid-alkali balance in saliva. Various parts of medicinal plants help maintain periodontal health. Glycyrrhiza glabra, Ficus religiosa, and Plantago major effectively inhibit primary plaque colonizers and periodontal pathogens. Medicago sativa, Aloe barbadensis Miller, and Trifolium pratense have excellent applications in treating periodontal diseases. Mangifera indica, Pongamia pinnata, the husk of Cocos nucifera, the root of G. glabra and Curcuma longa, leaves of Psidium guajava and Azadirachta indica, fruits of Citrus medica and Punica granatum, Ocimum Moringa oleifera extract, and pomegranate peel extract can serve as a promising alternative in managing chronic gingivitis. The anti-inflammatory, antioxidant, antibacterial, and astringent action of extracts obtained from various parts of medicinal plants make them effective in reducing gingival and periodontal diseases. Herbal medicine may be a viable alternative to contemporary pharmaceuticals as an adjuvant to scaling and root planning procedures.

Mechanism of Polaronic Conduction in Olivine Phosphates: An Influence of Crystallite Size

We report the polaronic conduction mechanism in transition-metal phosphate with different crystallite sizes by performing broadband ac conductivity measurements. The conductivity spectra exhibited a frequency-independent dc conductivity at low frequencies, and the conductivity becomes frequency-dependent above the characteristic frequency. The temperature-dependent dc conductivity has been analyzed within the framework of Mott’s model of polaronic conduction, which exhibits non-Arrhenius behavior within the hopping conduction region. The apparent non-Arrhenius behavior is divided into three different regions depending on the type of lattice phonons associated with the bound charge carrier. Interestingly, at high temperatures, the dc conductivity is primarily determined by the polaron concentration, and it varies with temperature. To ascertain the temperature-dependent polaron concentration variation at high temperatures, the frequency-dependent conductivity spectra have been analyzed by scaling procedure individually on three distinct regions. The application of the Summerfield scaling law on the ac conductivity spectra at low- and intermediate-temperature regions follows the time–temperature superposition principle (TTSP). On the other hand, at high temperatures, the scaling of the ac conductivity spectra with the Summerfield scaling law was found to exhibit pronounced deviations. The scaling of the ac conductivity spectra at high temperatures was improved significantly using the random barrier model. We suggest that at high temperatures, the number density of polarons performing a long-range hopping process becomes a temperature-dependent quantity and increases with temperature.

An analysis of the characteristics and motives of the UK homicides involving acts of dismemberment

PurposeThe purpose of this study was to contribute to the evidence base by analysing the characteristics and motives of homicides involving acts of dismemberment.Design/methodology/approachThe current study explored offence, victim and offender characteristics and the motives for 71 homicides involving dismemberment using open source data. All cases included in this study were investigated in the UK between 1970 and 2016. A non-metric multi-dimensional scaling procedure smallest space analysis (SSA) was used to explore the characteristics and motives derived from a content analysis of homicide data sourced online.FindingsA distinction between expressive and instrumental characteristics was observable with three thematic regions identified: instrumental – defensive, instrumental – predatory and expressive – affective. Support was found for previously identified motives for criminal dismemberment, with defensive being the most common motive identified in 63% (N = 45) of the cases.Originality/valueThe implications of the findings are discussed with suggestions made for future research. The findings have practical implications for assisting law enforcement and forensic and clinical practitioners in further understanding offenders who engage in homicidal dismemberment. This includes aiding homicide investigations, in terms of supporting investigators to draw upon offence, victim and offender characteristics and motives for homicides involving acts of dismemberment. Differentiation between cases of dismemberment and understanding of motives also has practical implications for the development of interventions and treatment pathways for homicide offenders who dismember victims.

Revised mixing coefficient scaling for sheared stably stratified turbulence

We revisit and extend the turbulent Froude number ( $Fr_k$ ) scaling for the mixing coefficient ( $\varGamma$ ) introduced by Garanaik &amp; Venayagamoorthy (GV) (J. Fluid Mech., vol. 867, 2019, pp. 323–333) by directly incorporating the effects of mean shear through the non-dimensional shear parameter $S_{\ast } = S k/\epsilon _k$ . For flows where the effects of mean shear are stronger than the background vertical stratification, we find $\varGamma \sim Fr_k^{-2} S_\ast ^{-1}$ for weakly stratified sheared turbulence and $\varGamma \sim Fr_k^{-1}S_\ast ^{-1}$ for moderately stratified sheared turbulence. The scaling procedure is inconclusive for strongly stratified sheared turbulence, but using two independent datasets of homogeneous, sheared, stably stratified turbulence, we empirically observe $\varGamma \sim Fr_k^{-0.5} S_\ast ^{-1}$ . Our revised scaling better collapses both datasets compared with the original GV scaling, and we note that the moderately stratified sheared regime is extremely narrow (or maybe even non-existent). We also apply our scaling to the time-varying open channel simulations of Issaev et al. (J. Fluid Mech., vol. 935, 2022) and observe $\varGamma \sim Fr_k^{-2}S_\ast ^{-1}$ for weakly stratified sheared turbulence, but we observe deviations from our revised scaling for moderate and strong stratifications due to time-varying mean shear and vertical transport. Finally, we apply our revised scaling to field measurements of Conry, Kit &amp; Fernando (Environ. Fluid Mech., vol. 20, 2020, pp. 1177–1197) and observe $\varGamma \sim Fr_k^{-2} S_\ast ^{-1}$ . We emphasize that our revised scaling is applicable only for stably stratified, vertically sheared turbulence with weak spatio-temporal variations of the mean shear and stratification, and we expect different scaling to apply when additional effects such as depth-varying radiative heating/cooling are present or when the orientation of the mean shear relative to the gravity vector is modified (e.g. horizontal shear).

Comparison of efficacy of 0.05% sodium hypochlorite with 0.2% chlorhexidine as A pre-procedural mouthrinse in periodontitis patients

: The objective of the study is to compare the efficacy of 0.05% sodium hypochlorite and 0.2% chlorhexidine as a pre-procedural mouth rinse for routine periodontal procedures to reduce the amount of aerosols containing infectious agents. A study was designed to be conducted on patients reporting to the outpatient department of Periodontology at Buddha Institute of Dental Sciences &amp; Hospital, Patna. Patients with generalized severe chronic periodontitis were divided into 3 groups. 15 patients were made to rinse with 0.05 % sodium hypochlorite for 1 minute, (Group A), 15 patients with 0.2% chlorhexidine (Group B), and 15 patients with normal saline (Group C) for 1 minute before routine ultrasonic scaling procedure. A blood agar plate exposed at 20 inches from the patient’s oral cavity was used for microbial sampling. It was incubated at 27°C for 24 hours and colony forming units (CFUs) were counted thereafter.: There was statistically significant differences in the number of CFUs of the different groups.: Both 0.05% sodium hypochlorite and 0.2% chlorhexidine were effective in reducing aerosol contamination during ultrasonic scaling but 0.05% sodium hypochlorite had a significantly better effect than 0.2% chlorhexidine.

Psychometric Analysis of the Quarantine Coping Strategies Scale (Q-COPE) in the Spanish Language

The possibility of facing an epidemic or pandemic resulting in mandatory isolation or quarantine has become a relevant construct for comparing and evaluating coping strategies under such conditions. The objective of this research was to develop and analyze the psychometric properties of a scale to assess quarantine coping strategies (Q-COPE). This was an instrumental study and 1110 Peruvian adults (M = 26.9 years; SD = 9.77) participated in the context of social isolation. For the construction of the scale, qualitative and quantitative procedures were followed. The internal structure was evaluated by exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). The content analysis by expert judges supports the representativeness of the items related to the construct. EFA and CFA allowed the establishment of five factors: Emotional regulation, Information, Accommodation, Social support, and Altruism. The first-order model presents adequate goodness-of-fit indices: χ2 = 489.048, df = 220, χ2/df = 2.223, SRMR = 0.025, CFI = 0.969, TLI = 0.965, RMSEA = 0.047. Likewise, the second order model presented similar values: χ2 = 499.674, df = 225, χ2/df = 2.221, SRMR = 0.026, CFI = 0.969, TLI = 0.965, RMSEA = 0.047. The 23-item version was consistent with the proposed theory, obtained adequate fit indices and acceptable factor loadings (>0.70), and presented good internal consistency indexes evaluated by Cronbach's α, ordinal α, omega (ω), and H coefficient. It is concluded that the Q-COPE scale presents good psychometric properties that justify its use in an adult population and allows the assessment of the coping strategies that people use in the face of a quarantine situation.
