The measurement of patient satisfaction can provide information about the success of the care provider in reaching the values and meeting the expectations of the patient. The purpose of this study was to translate into the Portuguese language and to culturally customize to the Brazilian population the instrument to measure patient satisfaction with physical therapy elaborated by Goldstein et al. The study sample was made up of 279 patients who were undergoing physical therapy treatment at 39 different private clinics in a middle-sized town in northeastern Brazil. For the translation of the survey instrument, the back-translation technique was employed, in association with the bilingual method. The reliability and validity of the Brazilian version of the instrument were both assessed. Reliability analysis, carried out with the computation of Cronbach alpha coefficients, showed that the measures obtained with the instrument have a high degree of internal consistency. The aspects dealing with the patient therapist relationship are the most important predictors of satisfaction, followed by those dealing with courtesy, privacy, and practical aspects such as efficiency of the facility in the patient admissions process, setting up of appointments, and waiting time in waiting room. Items dealing with aspects such as location of the facility and availability of parking facilities may underestimate the reliability of the instrument. This study translated, culturally customized, and validated an instrument to measure patient satisfaction with physical therapy originally developed in English. By so doing, this study has made this instrument available to the Brazilian society, and it has rendered it a useful parameter that can be utilized in our country in the field of physical therapy

The Nursing Process (NP) is considered as the dynamics of the systemized and inter-related actions of human care. We believe that the nursing manager, as the representative of all the nursing care provided in the hospital setting, is an important agent for the implementation of institutional policies, such as the NP, in the service. However, there is little information in the literature about the NP in the perspective of the nurse manager. The objective of this study was to analyze the viability of the Nursing Process in the hospital context based on the attitudes of the nurse managers toward the Process. We conducted a descriptive-exploratory research study, of quantitative approach, with a population of 45 nurse managers that worked in the state hospitals located in Natal, RN and in the university hospitals of the UFRN. Two instruments were used for the collection of data: a nursing process questionnaire, constructed for use in this study, and the scale for the measurement of the attitudes titled Positions on the Nursing Process. The population is predominantly feminine (91,0%) and have relative nursing practice experience (Mean=17,6 years). However, they have little experience in management (Mean=8,6 years). They express little knowledge of the PE nursing terms and little experience with the Process. They have a positive atitude toward the NP (Mean = 110,9); are favorable to its developement in the service (86,7%); 48,9% indicated little possibility of institutionalization in the service and 37,8% indicated large possibility. The Spearman test for association between the variables of attitude about the NP and the possibility of its institutionalization demonstrated a weak negative association in the total individual scores of the attitudes (-,316) as in the 20 itens of the instrument, with coefficients varying from 0,014 to 0,464. Factorial analysis of the instrument identified three underlying factors to the attitudes of the managers in this study: relevance, operationalization and collaboration, with Cronbach Alpha coeficients of 0,955, 0,844 and 0,807, respectively, and 0,956 for the whole instrument, indicating that the scale and its factorial subscales have internal consistency. We conclude that there is a weak tendency for the managers with a favorable attitude to have a negative perception about the possibility of institutionalization of the NP in the service. The favorable position does not appear to be sufficient for the viability of this methodology in the hospital sector, results that is worrisome for nursing. This situation suggests that the difficulties with the institution of the NP in the hospitals may be related to other factors, including the organizational conditions. We believe that the institucionalization of the NP in a servisse where it is not known and not practiced, constitutes the introduction of an innovative work technology that involves many demands, among them the adherence of the persons to the proposed innovation. This demands time and the institutional adjustments and the human resources necessary. In this process, the involvement of the health professional of the institution is necessary. This situation brings to light the discussions of professional autonomy, the action limits and perspectives, the redefinition of roles, delimiation (or consensus) of the objects of study and of the work processes, among others.

Exploratory descriptive study, prospective with quantitative approach, performed in the nefrology outpatient service from the Onofre Lopes University Hospital (HUOL), Natal/RN, aiming to identify aspects that concern Quality of Life (QOL) on transplanted and hemodialysis patients, as measured by WHOQOL-bref and describe the aspects that differentiate QL between the two groups as measured by the same instrument. The population was of 62 renal patients in hemodialysis and 58 transplantd, with data collected from february to march 2006. The instrument used was WHOQOL-bref, translated to and validated for Portuguese by the multicentric group of the World Health Organization (WHO) in Brazil. The results show predominance of the masculine gender both in the post-transplant group (55,17%), as well as in the hemodialysis group (51,61%); the age strip of 28 to 43 prevailed, among which were 53,45% transplanted and 48,99% hemodialysis patients; 79,93% of the hemodialysis patients and 62,07% of the transplanted were provenient from ouside the capital of the state; from the hemodialysis population, 59,68% were married, while among the transplanted 48,28% were single; 58,06% of the hemodialisys patients had 1 to 3 children, while the majority of the transplanted, 44,83%, had no children; regarding scholarity level on both groups, there was a predominance of incomplete fundamental school, representing 62,9% of the hemodialysis patients and 46,6% of the transplanted; regarding work status, 98,39% of those in hemodialysis informed not to be working, and the same applied to the transplanted, with 75,86%; regarding treatment time, most patients of both populations were in the 1- to 4-year interval, of which were 62,9% of the hemodialisys patients and 53,45% of the transplanted. The analysis of WHOQOL-bref reliability through Crobach s Alpha coefficient had a value of 0,8816, demonstrating good internal consistency for the instrument. Regarding description of QOL tests, the average scores of the post-transplant were (Q-1) 18,14 e (Q-2) 18,69, and 12,3 (Q-1) and 11,29 (Q-2) for the group in hemodialisys. Regarding the aspects that differentiate QOL on the two groups observed through average scores from the Domains: Physical, 15,91 for the post-transplant group and 12,71 for the hemodialisys group; Psychological, 16,75 for the post-transplant group and 14,84 for the hemodialisys group; Social Relations, 17,79 on the post-transplant group and 16,58 on the hemodialisys group; Environment, 14,16 on the post-transplant group and 12,38 on the hemodialisys group. On every evaluated item, the post-transplant group achieved higher scores when compared to the hemodialisys group. The diference in QOL for both populations was significant on all items evaluated with a p<0,005

Introduction: The human gestation period is 40 weeks. This is the essential time for maternal psychosocial adaptation, in which there is the intense transformation of a life without offspring into a life with one or more children. The Pregnancy Self-Evaluation Questionnaire (PSEQ) has 79 items, subdivided into seven subcategories: acceptance of pregnancy, identification with the maternal role, well-being of mother and baby, preparing for labor, control in labor, relationship with the mother and the relationship with the partner. Objective: To translate and cross-culturally adapt the instrument PSEQ to be used with Brazilian women. Methods: It is a cross-sectional observational study. We followed some methodological steps to achieve the cross-cultural adaptation of this measuring instrument. They are: translation, synthesis, back translation, analysis of the committee of specialists and pre-test. Another questionnaire was applied to characterize the socio-demographic and clinical status of the pregnant women (n = 36). The descriptive statistics was gotten through the average, standard deviation (SD), absolute and relative frequency. The statistical test used for the analysis of the internal consistency was Cronbach's alpha coefficient, using SPSS version 17.0. Results: The volunteers had low socioeconomic status, average age of 25.1 years (± 5.52), and average gestational age of 25.9 weeks (± 8.11). 58.3% of these volunteers had not planned their current pregnancy. The pretest showed that 75% of pregnant women found the questionnaire easy to understand. There was an average of 76.9 (± 3.23) answered items among the participants. Regarding the instrument PSEQ, the identification with the maternal role was the subcategory which showed the highest average 24.8 (± 5.6), while the relationship with the mother had the lowest average 15.4 (± 7.7). The internal consistency ranged from 0.52-0.89. Conclusion: The translation and cross-cultural adaptation of the PSEQ to Portuguese language were carried out with methodological rigor and can be considered an instrument with good internal consistency

Millon describes the normal personality by means of adaptation styles that are effective in normal environments and personality disorders such as unadapted operating styles. To operacionalize his theoretical model, Millon has built several instruments, including the Millon Clinical Multiaxial Inventory III (MCMI-III), wich consists of a self report inventory composed by 175 true or false response items, containing four verification scales, and others scales wich evaluates 14 personality patterns and 10 clinical syndromes. The Substance Dependence scale (T) is placed along with Clinical Syndromes scales. This research is justified by the lack of a Brazilian instrument to assess personality psychopathological aspects, and aims to translate and semantically adapt the MCMI-III to the Brazilian context, checking validity elements of the Substance Dependence scale, and developing a computer application for assisting the evaluation of assessment results. To this intent, 2.588 individuals data was collected, male and female, aged between 18 and 85 years, characterized as belonging to a clinical or non-clinical group, who took part in the survey via the internet or in person. Respondents completed the MCMI-III, a socio-demographic questionnaire and a subgroup also answered to the Goldberg General Health Questionnaire (GHQ). Besides descriptive statistics, we performed the analysis using the Student t test, principal components analysis and internal consistency. Despite difficulties related to translating very specific English terms, the assessment by judges, experts on Millon´s theory, and the back translation, attested the adequacy of the Brazilian version. Factorial analysis indicated the grouping of translated T scale items into three factors (social activities prejudice, lack of impulse control, and oppositional behavior), by presenting a single item on a fourth factor (apparently related to seeking pleasurable stimuli). The Cronbach alpha for this set of items was 0,82, indicating an acceptable scale reliability. The data analysis resulted in distinction of scores between clinical and non-clinical groups and between men and women; the relationship between high scores on the scale T and the other scales; scores of drug users according to the declared used substance; and the relationship between high scores on T and the verification of disorder or risk on GHQ mental health factor, indicating the instrument´s adequate sensistivity in identifying psychopathologies and the relationship between the different disorders or psychopathological personality patterns. Although further studies are necessary to develop the scores transformation factors, the computerized correction tool was adequate.

The objective of this dissertation is the development of a general formalism to analyze the thermodynamical properties of a photon gas under the context of nonlinear electrodynamics (NLED). To this end it is obtained, through the systematic analysis of Maxwell s electromagnetism (EM) properties, the general dependence of the Lagrangian that describes this kind of theories. From this Lagrangian and in the background of classical field theory, we derive the general dispersion relation that photons must obey in terms of a background field and the NLED properties. It is important to note that, in order to achieve this result, an aproximation has been made in order to allow the separation of the total electromagnetic field into a strong background electromagnetic field and a perturbation. Once the dispersion relation is in hand, the usual Bose-Einstein statistical procedure is followed through which the thermodynamical properties, energy density and pressure relations are obtained. An important result of this work is the fact that equation of state remains identical to the one obtained under EM. Then, two examples are made where the thermodynamic properties are explicitly derived in the context of two NLED, Born-Infelds and a quadratic approximation. The choice of the first one is due to the vast appearance in literature and, the second one, because it is a first order approximation of a large class of NLED. Ultimately, both are chosen because of their simplicity. Finally, the results are compared to EM and interpreted, suggesting possible tests to verify the internal consistency of NLED and motivating further developement into the formalism s quantum case

The Nursing Homes are an important alternative care in the world, but Brazil still has no valid instrument to monitor the quality these institutions. In the United States, the Observable Indicators of Nursing Home Care Quality Instrument (OIQ) is used to assess the quality of Nursing Home care using 30 indicators of structure (2 dimensions) and process (5 dimensions) related to quality person-centered care. The present study aimed at cross-culturally adapting the OIQ in order to evaluate the quality of Nursing Home care in Brazil. Conceptual and item equivalence were determined to assess the relevance and viability of OIQ in the Brazilian context, using the Content Validity Index (CVI) and a group of specialists composed of 10 participants directly involved in the object of study. Next, operational, idiomatic and semantic equivalence were carried out concurrently. This consisted of 5 phases: (1) two translations and (2) their respective back translations; (3) formal appraisal of referential and general meaning; (4) review by a second group of specialists; (5) application of the pretest at three Nursing Homes by different social entities: health professionals, sanitary surveillance regulators and potential consumers. Measurement equivalence was evaluated by the Cronbach’s alpha test to verify the internal consistency of the instrument. To measure inter-evaluator agreement, the General Agreement Index (ICG) and Kappa coefficient were used. Timely compliance and 95% Confidence Interval of indicators, dimensions and total construct were estimated. The CVI obtained high results for both relevance (95.3%) and viability (94.3%) in the Brazilian context. With respect to referential meaning, similarity was observed, ranging between 90-100% for the first back translation and 70-100% for the second. In relation to general meaning, version 1 was better, classified as “unchanged” in 80% of the items, whereas in version 2 it was only 47%. In the pretest, the OIQ was easy to understand and apply. The following outcomes were obtained: a high Cronbach’s alpha (0.93), satisfactory ICG (75%) and substantial agreement between the pairs of evaluators (health professionals, regulators from the Superintendency of Sanitary Surveillance –SUVISA-, and potential consumers), according to the Kappa coefficient (0.65). It´s possible take the operational equivalence held since it preserved the original layout in the Brazilian version from the maintenance in application mode, response options, number of items, statements and scores. The performance of nursing homes obtained approximate average scores of 87, a variation 55-111 considering a range from 30 to 150 points. The worst outcomes were related to process indicators with a mean of 2.8 per item, while structure was 3.75 on a scale of 1 to 5. The lowest score was obtained for the care dimension (mean 2). The OIQ version was deemed to be a valid and reliable instrument in the Brazilian context. It is recommended that health professionals, regulators and potential consumers adopt it to access and monitor the quality of Nursing Home care and demonstrating opportunities for improvement.

The abusive use of alcohol is closely related to dependence and to social and work damages. The main focus of this thesis is to create an instrument about alcohol abuse, in order to differentiate the degree of commitment of the symptomatology, considering its psychosocial factors of prediction. As specific goals: I) characterize the state of the art about assessment related to the abuse and dependence to alcohol; II) investigate and systematize aspects related to the predictive psychosocial factors for alcohol dependence; III) build an instrument for the assessment of alcohol abuse and protection and risk factors for the development of an alcohol dependence; and IV) verify validity evidence of the instrument built for the Brazilian population. In Study I, it was possible to observe the prevalence of articles related to the use of alcohol in a problematic way, without a classification dependence, it is lower than the one of articles that investigate the disease when it is already manifested, not to mention a few systematic studies about the theme of alcohol abuse in the scientific environment. In Study II, focus groups (FGs) were conducted, the analysis about the discourses of the focus groups were made through the ALCESTE software and it was possible to observe a response pattern that existed among the participants in different groups, with the generation of five classes. In Study III, we developed an instrument that contemplated aspects of the Alcohol Dependence Syndrome of the Millon Clinical Multiaxial Inventory-III, in addition to the characteristics defined in Study I and in Study II. The final version of the instrument had 59 items assessed through the likert scale of five points. In Study IV, the administration of the instrument was performed in an online format with university students ranging from 18 to 24 years old, residents in Brazilian metropolitan cities. The results evidenced that the internal consistency of the instrument is considered satisfactory (α = 0,882) and in what it refers to classes, the most significant data was the one related to financial loss and criteria for the diagnosis of alcohol abuse. It is important to consider the evaluative potential of risk and protective factors for the development of alcohol dependence of the instrument as a whole. Once the indicators of abuse and the profile of the abusers has been modified, the patient may have his/her treatment/intervention focused on the trouble and/or specific syndrome, thus having a clear and fast improvement.

INTRODUCTION: Humanized and quality prenatal and post-partum care is critical to maternal and newborn health, as well as oral health care. Currently, the National Oral Health Policy is aiming at expanding dental care for pregnant women. Thus, the promotion of oral health and attention to prenatal care policies should be integrated; however, there is still limited participation of pregnant women. Thus, it is necessary to verify the knowledge of pregnant women related to oral health, seeking to estimate the quality of dental care provided during prenatal care, being essential for the Family Health strategy to organize personnel, plan costs and to ensure the quality standard of care. OBJECTIVE: To develop and validate a research instrument on the knowledge of pregnant women about their oral health and of their baby. METHOD: This is a construction and validation study with 93 pregnant women in Family Health Units and specialized private clinics in Obstetrics, in the city of Natal / RN. It was authorized by the Onofre Lopes University Hospital Ethics Committee of the Universidade Federal do Rio Grande do Norte (UFRN) under the registration number 421.163/13. The construction of the instrument followed steps so that it was valid, reliable and sensitive: creation and reduction of the items (drafting of the instrument), content validity and testing of the instrument, and hypotheses validation. Once constructed, the instrument was evaluated by experts who suggested modifications. There was consultation with the target population about the new version of the created instrument, which had the instrument validation verified by internal consistency through intra and inter-calibration and test-retest. Next, the hypotheses were validated. A database was built in the Statistical Package for Social Sciences (SPSS), version 22.0. After creating the hypotheses, an association was found for validating the criteria between each of the specific issues for each established criteria, considering a 5% significance level. Data analysis was carried out by describing the absolute and relative frequencies of the variables pertaining to issues relating to their pregnancy knowledge about their oral health and their baby. The Kappa coefficient was used for the calibration process (Inter and Intra-examiner calibration) and Cronbach's alpha coefficient was used to analyze instrument reproducibility (test-retest). In addition, the chi-square test was used to cross the dependent variable with the (dichotomized) independent variables. RESULTS: The intra and inter agreement analysis presented a Kappa coefficient between 0.400 and 1.000. Internal consistency through the analysis showed that 90% of the instrument's questions showed great reliability in the answers (Cronbach α ˃ 0.7). In the investigation of the relationship between the dependent variable (knowledge about oral health) and the independent variables (trimester of pregnancy, education, income and multiparous), it was found that none of these independent variables were significantly associated. All hypotheses had their Ho confirmed. CONCLUSION: The constructed instrument was validated, considering that it showed to be sensitive with good reliability and good accuracy, and therefore can be used to assess pregnant women’s knowledge about their oral health and the oral health of their baby.
