description: A temperature accelerated life test on Upright Metamorphic Ga0.37In0.63P/Ga0.83In0.17As/Ge triple-junction solar cells has been carried out. The acceleration has been accomplished by subjecting the solar cells to temperatures (125, 145 and 165°C) significantly higher than the nominal working temperature inside a concentrator (90°C), while the nominal photo-current (500 suns) has been emulated by injecting current in darkness. The failure distributions have been fitted to an Arrhenius-Weibull model resulting in an activation energy of 1.39 eV. Accordingly, a 72 years warranty time for those solar cells for a place like Tucson (AZ, USA), was determined. After the ALT, an intense characterization campaign has been carried out in order to determine the failure origin. We have detected that temperature soak alone is enough to degrade the cell performance by increasing the leakage currents, the series resistance, and the recombination currents. When solar cells were also forward biased an increase of series resistance together with a reduction of short circuit current is detected. The failure analysis shows that: a) several metallization sub-products concentrate in several regions of front metal grid where they poison the silver, resulting in a two times reduction of the metal sheet resistance; b) the metal/cap layer interface is greatly degraded and there is also a deterioration of the cap layer crystalline quality producing a huge increase of the specific front contact resistance, c) the decrease of short circuit current is mainly due to the GaInP top subcell degradation.

description: We demonstrate that the conductance switching of benzo-bis(imidazole) molecules upon protonation depends on the lateral functional groups. The protonated H-substituted molecule shows a higher conductance than the neutral one (Gpro>Gneu), while the opposite (Gneu>Gpro) is observed for a molecule laterally functionalized by amino-phenyl groups. These results are demonstrated at various scale lengths : self-assembled monolayer, tiny nanodot-molecule junction and single molecules. From ab-initio theoretical calculations, we conclude that for the H-substituted molecule, the result Gpro>Gneu is correctly explained by a reduction of the LUMO-HOMO gap, while for the amino-phenyl functionnalized molecule, the result Gneu>Gpro is consistent with a shift of HOMO, which reduces the density of states at the Fermi energy.

description: Contingent valuation is used to measure the social impacts of tourism in rural Oregon communities. Impacts are substantial, for example, annual household willingness to pay (WTP) to reduce traffic congestion is $186. Study features include tests of sensitivity to a change in scope, tests of stability across survey mode, and a thorough system of no vote follow-up questions in a referendum format. While there is no evidence of scope effects (at the 0.05 level), results indicate that conclusions regarding sensitivity to scope may be dependent on the test used. WTP estimates are substantially less with the mail versus telephone survey mode.

description: Promoting community governance and service innovation is the theme of the times for comprehensively deepening reforms in the field of community construction. The stability and development of the most basic rural community is another important task of community governance. The current rural social governance work is extremely weak, seriously affecting the process of the entire social governance work. Constructing the path of rural community governance has become an important task for the majority of theoretical workers and grassroots practitioners. Taking Chaoyang Community, Tongchuan District, Dazhou, Sichuan Province as an example, with the goal of creating a community with the rule of law, peace, harmony, beauty and livability, a new model and new path to build community governance is proposed in this article.
Digital dental radiographs : influence of image quality and software manipulation on their interpretation
Creators: name: Delantoni, Antigoni
Publisher: name: University of British Columbia
Year: 2009

description: With the technologic advances in digital systems there has been a development in the field of digital imaging. Systems have developed that allow us to take radiographs with a reduced patient exposure and higher convenience compared to conventional film. In many cases the information is electronically transferred either to get a second opinion or to share information. We need to know to what extent there is significant information loss with digital systems. It is therefore useful to compare the image quality of digital systems to conventional film. The aim of this study was to evaluate the amount of diagnostic information loss during the scanning of conventional radiographs by comparing images of different qualities for periodontal defects. Radiographs were taken and scanned at different resolutions (600,300,150 and 75dpi). A visual analog scale was used for the subjective assessment of image quality. Observers were asked to mark points on the selected images. Analysis of Variance was used to demonstrate significant differences. From the results we obtained from our data, no significant differences were found between the resolutions of 600 and 300 dpi, while there were differences between low quality images (75 dpi) and the higher ones. We drew conclusions as to whether there is significant amount of information loss during the scanning of radiographs in cases of periodontal defects. In addition to the periodontal model, further study on image manipulation by blurring was done using an endodontic model, and the subjective and objective performances and measurements of the observers were compared. The feature of blurring was selected since it is a feature present in Microsoft PowerPoint and no studies had been done on it in the past. The images were blurred using a blurring feature provided by software by the NIH image, and a comparison was made between blurred and non-blurred images for good and poor quality images. Differences were found in the points' distribution and the measurements between the two features. We concluded that blurring worsens good quality images, while poor quality images are improved.

We introduce expansion-normalised variables and investigate the late-time asymptotic behaviour of the models and determine the late-time asymptotic states. For the Bianchi type VIII models the state space is unbounded and consequently, for all non-inflationary perfect fluids, one of the curvature variables grows without bound. Moreover, we show that for fluids stiffer than dust ($1

description: The GATT/Uruguay Round trade negotiations have resulted in a multilateral relaxation of beef trade restrictions. A linear elasticity model of the U.S. beef industry is developed using log differentials equations. Beef consumption, production, and trade are disaggregated into appropriate ground and table cut components. The model predicts that GATT/Uruguay Round will cause asymmetric effects on ground and table cut beef consumers. In general, fed cattle and cow/calf producers will benefit from trade liberalization because of increases in fed and feeder cattle prices. However, nonfed cattle price will decrease.

description: Tritrichimonas foetus vaccine has been marketed since 1989 to combat the trichomoniasis disease that causes reproductive failure and considerable economic loss to Nevada ranchers. An ex post technology adoption model is estimated to examine the possible adoption rate, to identify the factors that may influence the adoption behavior, and to test how the probability of adoption for five possible adopter groups would change due to changes in various ranch specific factors. Results indicate that use of computers, veterinary checkup of herd, and herd size influence the probability of adoption. Model results show that cooperative extension programs enhance the rate of adoption.

description: To analyze the temporal trends of atrial fibrillation (AF)-related ischemic stroke (IS) and their relationship with the prescription patterns of antithrombotic treatment from 2013 to 2019 in the Health Assistance Area of a regional hospital. First, a retrospective ecological study of aggregate data to analyze the annual incidence of IS between 2013 and 2019 was performed. Second, we selected those patients diagnosed with AF between 2013 and 2019 and performed a retrospective longitudinal study to assess the role of antithrombotic therapy in the development of AF-related IS. During this period, whereas the annual incidence of IS remained stable (from 1.3 in 2013 to 1.2 cases per 1000 inhabitants in 2019; adjusted P for trend .829), the annual incidence of AF-related IS decreased over time (from 23.8 to 18.8 cases per 1000 inhabitants, respectively; adjusted P for trend .001). Among AF patients, the use of direct oral anticoagulants increased from 5.5% to 46.8%, while the prescription of antiplatelets and vitamin K antagonists decreased from 21.9% to 6.0% and from 63.8% to 36.1%, respectively. Overall, the use of oral anticoagulants increased from 69.3% to 82.9%; p p The prescription of oral anticoagulants, particularly direct oral anticoagulants, has increased from 2013 to 2019 in our Health Assistance Area. This increase might partially explain the reduction in AF-related IS.

By considering the restriction of packets of irreducible representations we obtain another very simple branching law, which was conjectured in Orsted-Speh (arXiv:1907.07544).

Auteur or consummate professional? A historical study of the film career of John Schlesinger
Creators: name: Lane, Julie
Publisher: name: University of Leicester
Year: 2020
Subjects: Uncategorized

description: The career of the British film director John Schlesinger (1926-2003) spanned a period of forty years and was distinguished by a number of notable films made in Britain and the United States. Throughout the 1960s he would be increasingly appraised as a key director, culminating in the critical and commercial success of the Academy Award-winning Midnight Cowboy (1969). From the 1970s, however, critics frequently disapproved of his more commercial and genre-based projects, with a consensus emerging that Schlesinger had made artistic compromises and consequently declined.In the thesis, a more nuanced and balanced account of Schlesinger’s career and its fluctuations is presented by means of a detailed consideration of historical production and reception conditions. The varied production contexts within which Schlesinger worked, including British filmmaking of the early 1960s, the Hollywood Renaissance and big-budget studio production, are examined for the ways in which he was subject to a range of opportunities, constraints, collaborations and conflicts. Similarly, a recognition of film reviewing as historically situated and subject to ongoing change permits an examination of the ways in which conventions and shifting preferences in criticism influenced particular critical representations of Schlesinger.Throughout the study, Schlesinger’s agency and contemporary representations of it emerge as subject to a range of specific industrial and critical practices. Despite critics’ intimations that Schlesinger made artistic compromises in the latter part of his career, an examination of actual production and reception contexts indicates that he was consistently subject to particular limitations and that various changes occurring throughout his career would limit his opportunities for making the kind of films with which he had made his name. Inattentive to such realities and attached to the evaluative criteria that had earlier seen Schlesinger appraised as an auteur, film reviewing would work to enhance the sense of Schlesinger’s decline.

description: Regional live cattle prices are decomposed into two components: (a) a trend common to all regional cattle price series and (b) regional deviations or price dynamics around that trend. Tests are developed to determine if market factors are related to the regional price deviations around a common trend. Slaughter volume, distance between a market and the next closest, and forward contract deliveries are significantly related to price deviations from the estimated common trend.

description: In this article, the degree of imperfect competition in the world market for soymeal exports is estimated using a structural econometric model. The procedure consists of estimating a demand function and the industry first-order profit-maximization condition, from which an estimate of the degree of market power can be retrieved. Using a nonlinear three-stage least squares procedure, the estimate of market power shows that the world market for soymeal exports is perfectly competitive. The empirical results also indicate that this market was competitive even prior to entry by Argentinean firms in the mid-1970s.

description: Producers in southwest Oklahoma lack adequate information about optimal planting decisions for cotton. This study uses a cotton growth simulation model to evaluate alternative cultivar, planting date, irrigation, and harvest choices. Effects of using information about soil moisture at reproduction and revenue loss at harvest in making cultivar and planting data decisions are evaluated. Using soil temperature information to plant at an early date produced high net revenue some years, but reduced mean net revenue and increased risk. Producers maximizing expected net revenue should plant a short-season cultivar in late May and use soil moisture information to schedule irrigation at reproduction.

description: We analyse the dissociation of a photon in diffractive deep inelastic scattering in the kinematic regime where the diffractive mass is much bigger than the photon virtuality. We consider the dominant q\bar{q}g component keeping track of the transverse momentum of the gluon which can be measured as a final-state jet. We show that the diffractive gluon-jet production cross-section is strongly sensitive to unitarity constraints. In particular, in a model with parton saturation, this cross-section is sensitive to the scale at which unitarity effects become important, the saturation scale. We argue that the measurement of diffractive jets at HERA in the limit of high diffractive mass can provide useful information on the saturation regime of QCD.

description: BackgroundDespite recent advances, treatment options for patients with malignant pleural mesothelioma (MPM) are limited and prognosis remains poor. The aims of this work were to better understand the somatic copy number alteration (SCNA) landscape of MPM and to identify potential therapeutic targets, to determine genetic factors predicting outcome following radical surgery, and to develop an evolutionary study of MPM.MethodsThe Affymetrix Oncoscan array was used to evaluate SCNAs from 94 tumour samples. Common SCNAs were evaluated as potential therapeutic targets, including PRMT5 as a synthetic lethal target for MTAP in vitro. SCNA profiles of patients with extremes of outcome following radical surgery were compared to determine any genetic predictors of outcome. A second set of tumours was analysed in an attempt to validate these findings. A pilot of the Medusa study (NCT03654833) was carried out to evaluate the genomic spatial heterogeneity within 6 MPM tumours by whole exome sequencing.ResultsDeletion of 9p21.3 was the most prevalent SCNA. MTAP was shown to have potentially synthetic lethal interaction with PRMT5 in vitro. Deletion of CDKN2A was a truncal event in 67% of cases. BAP1 and NF2 were commonly heterozygously deleted, with mutation of the remaining allele a truncal event on phylogenetic analysis. A group of 47 SCNAs were exclusive to patients with a short time to progression, and having one or more of these predicted outcome.Conclusions Several potential therapeutic targets have been identified. The presence of one or more specific SCNAs could give a measure of prognosis for patients from routinely obtained tumour tissue samples.

Ebf1 as a nuclear matrix protein
Creators: name: Liepina, Inara
Publisher: name: University of Leicester
Year: 2020
Subjects: Uncategorized

description: EBF1 is a highly conserved transcription factor that plays pivotal roles in the development of normal and malignant B cells. In mice, homozygous loss of Ebf1 completely suppresses normal B-cell development, while heterozygosity results in decreased pro-B cell numbers and increased DNA damage accumulation upon UV light exposure. In man, EBF1 deletions are typically heterozygous and frequently occur in B-cell precursor acute lymphoblastic leukaemia. In contrast to EBF1 deletions, EBF1 mutations are found in mature B cell malignancies. Both mutations and deletions are thought to function via loss of EBF1’s transcriptional activities.Here, I show that Ebf1 depletion in Abelson transformed murine pro-B cells resulted in rapid cell cycle arrest associated with nuclear collapse and heterochromatin accumulation at the periphery of the nuclei. Using in situ fractionation, I was able to show that a fraction of EBF1 was detected in the isolated nuclear matrix fraction, suggesting that EBF1 might be involved in nuclear matrix regulation of pro-B cells. Preliminary proteomics data suggested that EBF1 might interact with nuclear structural proteins including SRSF2, RPL14 LGALS9 and MTDH; loss of function of these proteins might play a role in the nuclear collapse upon EBF1 depletion. EBF1 depletion also resulted in pro-B cell arrest at the G1 phase and rapid CCND3 protein degradation. CCND3 was previously shown to localize on the nuclear structural matrix in pro-B cells. Therefore, it was hypothesized that CCND3 might interact with EBF1 at the nuclear matrix. Here I show that EBF1 does not interact with CCND3, and they do not have a potential common structural binding partners. Conclusion: My data suggest that EBF1 may have functions within the nuclear matrix independent of its transcriptional activities.

We determine both the evolution equation for electron polarization, which takes the non-Abelian Berry phase into account, and Hamiltonian equations for trajectories of the particle (wave packet) center in the phase space. The equations have covariant form with respect to U(2) gauge transformations and contain topological spin terms that are connected to the Berry gauge field arising during the diagonalization of the Dirac equation. The trajectory equations obtained are substantially different from the traditional ones (for instance, those that follow from the Pauli Hamiltonian) and correspond to contemporary ideas of topological spin transport of particles.

description: Agroenvironmental problems (e.g., contamination of ground- and surface water, feed lot odors, endangered species) often involve goods and activities with public goods attributes. Grass roots collective action- in contrast to top-down governmental collective actions of taxing, subsidizing, and regulating- provides one alternative means of helping resolve these problems. Here I suggest that agroenvironmental policy, research, and extension should consider the often forgotten grass roots collective action alternative. I also discuss how expected private benefits, communication and information, joint products, group size and heterogeneity, transaction costs, and rules and enforcement determine the success or failure of grass roots collective action.

description: Gamma-ray bursts (GRBs) might be powered by a black hole (BH) hyperaccretion systems via the Blandford-Znajek (BZ) mechanism or neutrino annihilation from neutrino-dominated accretion flows (NDAFs). Magnetic coupling (MC) between the inner disc and BH can transfer angular momentum and energy from the fast-rotating BH to the disc. The neutrino luminosity and neutrino annihilation luminosity are both efficiently enhanced by the MC process. In this paper, we study the structure, luminosity, MeV neutrinos, and gravitational waves (GWs) of magnetized NDAFs (MNDAFs) under the assumption that both the BZ and MC mechanisms are present. The results indict that the BZ mechanism will compete with the neutrino annihilation luminosity to trigger jets under the different partitions of the two magnetic mechanisms. The typical neutrino luminosity and annihilation luminosity of MNDAFs are definitely higher than those of NDAFs. The typical peak energy of neutrino spectra of MNDAFs is higher than that of NDAFs, but similar to those of core-collapse supernovae. Moreover, if the MC process is dominant, then the GWs originating from the anisotropic neutrino emission will be stronger particularly for discs with high accretion rates.

description: In 2001, Rivest et al. firstly introduced the concept of ring signatures. A ring signature is a simplified group signature without any manager. It protects the anonymity of a signer. The first scheme proposed by Rivest et al. was based on RSA cryptosystem and certificate based public key setting. The first ring signature scheme based on DLP was proposed by Abe, Ohkubo, and Suzuki. Their scheme is also based on the general certificate-based public key setting too. In 2002, Zhang and Kim proposed a new ID-based ring signature scheme using pairings. Later Lin and Wu proposed a more efficient ID-based ring signature scheme. Both these schemes have some inconsistency in computational aspect. In this paper we propose a new ID-based ring signature scheme and a proxy ring signature scheme. Both the schemes are more efficient than existing one. These schemes also take care of the inconsistencies in above two schemes.

Effects of Central Bank Independence in Developing Countries

description: This thesis is composed of three empirical studies on the effect of central bank independence in developing countries. The first empirical study in Chapter 2 investigates the relationship between CBI and inflation in developing countries. After estimating a panel regression model, using pooled least square on the assumption of coefficient homogeneity; the result reveals that there is no significant negative relationship between CBI and inflation. The poolability of the panel is checked by applying the Chow test and Roy-Zellner test. The results show that the model is not poolable. Furthermore, by performing a panel heterogeneity model with pooled mean group (PMG) estimator and show that there exists a reverse relationship between CBI and inflation. Chapter 3 presents the responses to financial asset prices, consumption and investment in relation to CBI shocks in developing countries. The financial asset prices are divided into three categories: exchange rate, stock index and bond yield. The analysis is based on a panel Vector Autoregressive (Panel VAR) estimation. By applying poolability tests, heterogeneity across the countries in our sample is identified. One possible solution to this problem is to apply a mean-group estimation to the panel VAR. Additionally, the sample countries are divided to make the sub-group poolable. Chapter 4 examines whether CBI and macroprudential policy can contribute to enhancing financial stability in terms of credit per GDP. This chapter proposes a new index concerning macroprudential policy for 20 developing economies over the period 2000 to 2017. This chapter shows that the effect of CBI and macroprudential policy on credit per GDP depends on the non-linearity of the CBI degree. The more independent the central bank, the more stable its financial system, with a stronger effect when CBI is below its trend. When the sample is separated into two groups based on the poolability test, the result reveals that countries with a higher average CBI index maintain better financial stability.

description: Phenylketonuria (PKU) is a rare autosomal recessive disorder caused by a deficiency of phenylalanine hydroxylase (PAH). Its prevalence is estimated to be 1:10,000 in Europe. PKU is the commonest congenital inborn error of metabolism. The aim of our study was to investigate the characteristics of clinical practice in relation to PKU in Italy, in order to raise awareness about the current management and therapeutic approaches adopted. Six Italian experts conducted a systematic literature review as well as an internal survey to investigate the relevant clinical aspects. Collectively, the expert panel managed a total of 678 PKU patients treated in the early stages of the condition over a 16-year period across six centers. The management of PKU varied markedly between centers, with differences in the composition of the multidisciplinary team, dietary treatments, compliance and adherence to management, tetrahydrobiopterin use, and patient follow-up. Patients were mostly managed by a pediatric reference center from the initial PKU diagnosis during newborn screening until adulthood, without transition to a specialized adult clinician. Fogginess, concentration reduction, low attention, anxiety, irritability, memory deficit, headache, and unstable mood were common features in patients with uncontrolled blood phenylalanine levels (generally above 600 µmol/L). A homogeneous and shared approach to the management of PKU patients is important. Our survey demonstrates the current management of PKU in Italy, with the aim of promoting the implementation of therapeutic strategies and follow-up, increased patient compliance and adherence, and the achievement of the phenylalanine level targets recommended by European Union guidelines. Emerging therapies are likely to become a standard treatment for patients unable to comply with diet therapy and maintain their phenylalanine levels below the threshold values.

description: Compared with solid wood, one of the advantages of wood-based composites is the great potential for the design of material properties through manipulation of manufacturing variables. Large strides are presently being made in the design of non-veneer structural panels such as oriented strand board (OSB) by using material science and engineering principles. Scientists and engineers have been more successful in designing synthetic fiber-reinforced composites than wood-based composites, mainly because of the complexity of the microstructures and the inherent variability of the wood composites. In this study, recent research in modeling and predicting the properties of flakeboards has been summarized. The relationships among the structure in terms of void volume, density distribution, and the properties of the panels are discussed. With the help of a robotic system, very thin partially oriented wood assemblies were made and tested. The relationship between flake orientation and tensile strength and tensile MOE were determined. The relationship between density and tensile strength and tensile MOE were also examined. Based on layer properties, a three-layer mathematical model was derived to predict the tensile strength and tensile MOE. Partially oriented three-layer OSB panels were made and tested to verify this mathematical model. Very good agreement was found between this model and experimental results. Furthermore, a 3D finite element model was developed to simulate the probability of failure and probabilistic distribution of tensile strength of OSB. The probabilistic distributions of tensile strength and the load capacity probabilistic distributions for three-layer partially oriented OSB were predicted successfully. Good agreement between predictions and experimental data was observed.

description: An aortic aneurysm describes the irreversible degradation and dilation of the aorta. This can occur at many sites along the aorta but does so with varying frequency. A key clinical finding is the frequent observation of abdominal aortic aneurysms (AAAs) in comparison to those of the external iliac artery (EIA), which forms much later in embryogenesis, where they are seldom seen. This work tested the overall hypothesis that there is a fundamental difference in the structure of the aorta that influences a predisposition to aneurysmal disease. For this, tissue was collected from 16 aortic sites. Immunohistochemistry was used to quantify collagen and elastin; the percentage of both were similar from aortic root to the level of the renal arteries. From the renal arteries to the EIA, the percentage of collagen increases and was significantly higher than the percentage of elastin. Scanning electron microscopy investigated the collagen microstructure and identified that the mean collagen fibre diameter within the EIA wall was significantly larger than at the abdominal aorta. Finally, proteomic analysis identified proteins that could be taken forward for further analysis. These were quantified along the length of the aorta using IHC, to determine whether they may influence aneurysmal degradation. Difficulties in obtaining aortic wall samples meant other investigations were simultaneously pursued. Further work in this thesis aimed to identify biomarkers associated with increased AAA growth rate. This work used both Enzyme-linked immunosorbent assays (ELISAs) and metabolomics for the analysis of plasma from AAA patients. No significant association was found using the ELISAs, but metabolites putatively associated with increased AAA growth were identified using metabolomics. Finally, the association between low-density lipoprotein receptorrelated protein 1 (LRP1) and AAAs was investigated. The final part of work in this thesis aimed to quantify LRP1 activity and successfully developed two transient LRP1 knockdown models.

description: The mineral processing industry produces vast amounts of metallurgical waste streams which are increasing every year. However, this waste still contains a variety of economically important metals and could constitute a valuable secondary source for their production. Recovery of metals from aqueous solutions can be achieved by electrodeposition, cementation, precipitation and ion exchange. Due to the high operating costs and the associated environmental hazards, many of these processes have been characterized as inefficient. This study aims to introduce the DESs as an alternative medium for the recovery of metals from metallurgical wastes.The ionometallurgical recovery of Ag, Fe, Ni, Co, Sn, Cu, Zn and Pb is studied by electrowinning and cementation from low concentration solutions. It is shown that different metals exhibit different deposition rates and this can be linked to their electrochemical behaviour. Chemically reversible metals such as Ag, Sn, Cu and Pb exhibit relatively high deposition efficiencies with low impurity deposits in contrast with Fe, Ni, Co and Zn which show a non-reversible behaviour. Side reactions such as the degradation of the DES and the reduction of the water contained in it can cause issues during the deposition processes and lead to passivation.Fe, Zn and Pb are primarily found in most of the metallurgical wastes and their separation was further studied by solvent extraction and adsorption. During the former, the isolation of Fe and Zn from a mixture of the three metals is achieved by commercial extractants providing high selectivity. Waste materials from the egg industry showed adsorption capabilities towards the three metals with chemical reactions between the metal and the adsorbate to control the process. Selectivity of Fe over the others is also demonstrated as it has low market value and can negatively impact the deposition efficiencies of the other elements. A previously developed process for the recovery of metals from industrial jarosite waste is modelled using the HSC Chemistry® software to provide insight for the electrodeposition and cementation of metals. It was found that the recovery rates of Fe, Pb and Zn were low and that the process cannot be cost efficient under the current conditions. Overall recovery of metals using DESs was found to be potentially economically viable for high value elements from primary and secondary materials.

description: The Prescription Opioid Misuse and Abuse Questionnaire was developed to identify prescription opioid abuse and misuse among patients with chronic pain, however, evidence of construct validity and reproducibility is needed. Chronic pain patients were recruited from five Department of Defense Military Health System clinics across the United States. Construct validity was examined using subjective clinician-reported and patient-reported measures as well as objective information (e.g. hair/urine drug screens and electronic medical records). Test-retest reliability was assessed across 2 timepoints among a subgroup of patients with stable chronic pain. Of 3,263 screened patients, 938 (28.7%) met eligibility and were enrolled; 809 (86.2%) completed the Prescription Opioid Misuse and Abuse Questionnaire. Construct validity was supported by comparison to other validated questionnaires and hair and urine screens which yielded high agreements with patient reports on the Prescription Opioid Misuse and Abuse Questionnaire. Electronic medical record data supported patients’ Prescription Opioid Misuse and Abuse Questionnaire responses regarding physician and emergency room visits and opioid refills. The Prescription Opioid Misuse and Abuse Questionnaire had excellent test–retest reliability; the percentage agreement between the two Prescription Opioid Misuse and Abuse Questionnaire administrations was high (>90%) for most questions. Results suggest that the Prescription Opioid Misuse and Abuse Questionnaire is a valid and reproducible tool that can be used to assess the presence of prescription opioid misuse and abuse among patients with chronic pain.
