Einstellungen stellen als Teil der professionellen Handlungskompetenz von Lehrpersonen eine wichtige handlungsleitende Determinante des Unterrichtsgeschehens dar. Hierzu wird auf Basis der Theorie des geplanten Verhaltens ein Erwartungs-mal-Wert-theoretisches Einstellungsinstrument faktoriell validiert und der Zusammenhang der inklusiven Einstellung, Normvorstellung und Lehrerselbstwirksamkeitsüberzeugung mit der selbstberichteten Individualisierungspraxis von Lehrpersonen betrachtet. Die Ergebnisse einer exploratorischen Faktorenanalyse zeigen in Studie I drei Einstellungsfaktoren, die in Studie II konfirmatorisch bestätigt wurden. Studie III zeigt, dass die selbstberichtete Individualisierungspraxis durch die Normvorstellung und die Intention, sich den Herausforderungen eines inklusiven Unterrichtes anzunehmen, vorhergesagt werden kann. Die Intention mediiert dabei den Zusammenhang der selbstberichteten Individualisierungspraxis mit der Einstellung vollständig und mit der Normvorstellung partiell. Die Lehrerselbstwirksamkeitsüberzeugung sagt demgegenüber die selbstberichtete Individualisierungspraxis weder direkt noch indirekt vorher. (DIPF/Orig.)

Purpose This study aims to present the psychometric properties of the Portuguese version of the Positive Valuation of Life Scale (Lawton et al. in J Aging Ment Healt 13:3–31, 2001). Method Sample included 207 community-dwelling elders (129 women; MAge = 77.2 years, SD = 7.5). The data collection included the translated and adapted Portuguese version of Positive Valuation of Life Scale, Life Satisfac- tion Index Z, Meaning in Life Questionnaire and Geriatric Depression Scale. Results From exploratory factor analysis, two factors emerged, existential beliefs and perceived control, ex- plaining 49 % of the total variance. Both factors were positively related with meaning in life and life satisfaction and negatively related with depression (p\0.05). The values obtained for internal consistency for the total scale and for each subscale were good (a [ 0.75). Conclusion The Portuguese version of Positive VOL Scale represents a reliable and valid measure to capture the subjective experience of attachment to one’s life. The two-factor structure is an update to Lawton’s previous work and in line with findings obtained in the USA (Dennis et al. in What is valuation of life for frail community-dwelling older adults: factor structure and criterion validity of the VOL, Thomas Jefferson University, Center for Applied Research on Aging and Health Research, 2005) and Japan (Nakagawa et al. in Shinrigaku Kenkyu 84:37–46, 2013). Future research is required to investigate VOL predictors and the potential changes toward the end of the life span.

The study examined a modified social cognitive model of domain satisfaction (Lent, 2004). In addition to social cognitive variables and trait positive affect, the model included two aspects of adult attachment, attachment anxiety and avoidance. The study extended recent research on well-being and satisfaction in academic, work, and social domains. The adjusted model was tested in a sample of 454 college students, in order to determine the role of adult attachment variables in explaining social satisfaction, above and beyond the direct and indirect effects of trait positive affect. Confirmatory factor analysis found support for 8 correlated factors in the modified model: social domain satisfaction, positive affect, attachment avoidance, attachment anxiety, social support, social self-efficacy, social outcome expectations, and social goal progress. Three alternative structural models were tested to account for the ways in which attachment anxiety and attachment avoidance might relate to social satisfaction. Results of model testing provided support for a model in which attachment avoidance produced only an indirect path to social satisfaction via self-efficacy and social support. Positive affect, avoidance, social support, social self-efficacy, and goal progress each produced significant direct or indirect paths to social domain satisfaction, though attachment anxiety and social outcome expectations did not contribute to the predictive model. Implications of the findings regarding the modified social cognitive model of social domain satisfaction were discussed.

Burnout is a psychological syndrome triggered in response to continuous exposure to interpersonal stressors. It is considered a multifactorial construct, which is commonly characterized by three dimensions: emotional exhaustion, dehumanization, and lack of personal accomplishment.This study aimed to verify if the three characteristics of burnout (exhaustion, lack of dehumanization and personal accomplishment) are present in people working as guides Tourism in Natal - RN. It is a descriptive and quantitative study. 109 subjects were surveyed. Data collection was done through the use of questionnaires, the instrument used was the characterization of the Burnout Scale (ECB) created and validated in Brazil by Trocoli and Tamayo (2000). In order to analyze data we used descriptive statistics, analysis of core measures, exploratory and confirmatory factor analysis, reliability analysis, cluster analysis, multiple discriminant and Spearman correlation. Factor analysis identified four factors that explain 58.3% of the total variance. Those factors were named exhaustion, deception, avoidance, and dehumanization. The reliability of the instrument, as measured by Cronbach's Alpha was 0.918, which is considered excellent reliability. The 109 subjects were grouped into three cluster, which had the deception, avoidance, and dehumanization as discriminant. It is possible to conclude that the characteristics of burnout syndrome are present in the studied population where 19 people are on the high level of burnout, moderate in 32 and 56 in the light. The correlations between socio-demographic variables studied and the dimensions of burnout, were few and weak. The variable leave for health reasons in the study appeared to be related to feelings of exhaustion and avoidance behavior appeared related to younger individuals and who work only in the activity of Receptive Tourism Guide. Verification of the incidence of burnout in individuals surveyed suggest the need to adopt intervention strategies are individual, organizational and / or combined

This study presents the development and analysis of the psychometric properties of the Deviant Behavior Variety Scale (DBVS). Participants were 861 Portuguese adolescents (54 % female), aged between 12 and 19 years old. Two alternative models were tested using Confirmatory Factor Analysis. Although both models showed good fit indexes, the two-factor model didn’t presented discriminant validity. Further results provided evidence for the factorial and the convergent validity of the single-factor structure of the DVBS, which has also shown good internal consistency. Criterion validity was evaluated through the association with related variables, such as age and school failure, as well as the scale’s ability to capture group differences, namely between genders and school retentions, and finally by comparing a sub-group of convicted adolescents with a group of non-convicted ones regarding their engagement in delinquent activities. Overall, the scale presented good psychometric properties, with results supporting that the DBVS is a valid and reliable self-reported measure to evaluate adolescents’ involvement in deviance.

Skin self-examination (SSE) is promoted widely so that individuals will become familiar with their skin and be better able to identify suspicious changes earlier. However, individuals can also become familiar with their skin other than through purposeful SSE. In this article, we develop a measure of skin familiarity based on the density of spots on 14 different areas of the body. A factor analysis of the 14 body-area scores revealed that they could be grouped into four broad body regions (shoulders and back, front of legs, back of legs, and feet). Each total body score and body-region score has high internal consistency (Cronbach's alpha coefficients ranging from 0.79 to 0.93). Moreover, the scores correlate as expected with skin self-examination behaviors and other personal characteristics, indicating high construct validity. We consider the advantages that skin familiarity measures offer over the exclusive use of SSE measures in the assessment of early detection activities and discuss the direction of future research in this area

The Posttraumatic Growth Inventory (PTGI) is frequently used to assess positive changes following a traumatic event. The aim of the study is to examine the factor structure and the latent mean invariance of PTGI. A sample of 205 (M age = 54.3, SD = 10.1) women diagnosed with breast cancer and 456 (M age = 34.9, SD = 12.5) adults who had experienced a range of adverse life events were recruited to complete the PTGI and a socio-demographic questionnaire. We use Confirmatory Factor Analysis (CFA) to test the factor-structure and multi-sample CFA to examine the invariance of the PTGI between the two groups. The goodness of fit for the five-factor model is satisfactory for breast cancer sample (χ2(175) = 396.265; CFI = .884; NIF = .813; RMSEA [90% CI] = .079 [.068, .089]), and good for non-clinical sample (χ2(172) = 574.329; CFI = .931; NIF = .905; RMSEA [90% CI] = .072 [.065, .078]). The results of multi-sample CFA show that the model fit indices of the unconstrained model are equal but the model that uses constrained factor loadings is not invariant across groups. The findings provide support for the original five-factor structure and for the multidimensional nature of posttraumatic growth (PTG). Regarding invariance between both samples, the factor structure of PTGI and other parameters (i.e., factor loadings, variances, and co-variances) are not invariant across the sample of breast cancer patients and the non-clinical sample.

O Metacognitive Awareness Inventory (MAI) de Schraw e Dennison (1994) avalia duas dimensões metacognitivas de natureza geral nos adolescentes e adultos: o conhecimento da cognição, que inclui três subprocessos, e a regulação da cognição, que compreende cinco subprocessos. Neste estudo apresenta-se o processo de tradução e de adaptação do MAI à população portuguesa. A consistência interna nas dimensões conhecimento e regulação da cognição foi 0,82 e 0,90, respetivamente. Os resultados da Análise Fatorial Confirmatória sugerem um fator de segunda ordem com base na correlação dos resultados nas duas dimensões. A subescala conhecimento declarativo apresentou melhor validade relativa ao critério comparativamente com as demais subescalas. O MAI constitui-se um instrumento adaptado à realidade portuguesa, tanto para a avaliação da metacognição no global, como nas suas dimensões principais, permitindo apoiar a investigação relativa ao rendimento em processos de aprendizagem e formação na população adulta e de adolescentes.

Cracks or checks in biscuits weaken the material and cause the product to break at low load levels that are perceived as injurious to product quality. In this work, the structural response of circular digestive biscuits, with diameter 72 mm and thickness 7.2 mm, simply supported around the circumference and loaded by a central concentrated force was investigated by experiment and theory. Tests were conducted to quantify the distribution in breakage strength for structurally sound biscuits, biscuits with natural checks and biscuits with a single known part-through crack. For sound biscuits the breakage force is Normally distributed with a mean of 12.5 N and standard deviation of 1.2 N. For biscuits with checks, the corresponding statistics are 9.6 N ± 2.62 N respectively. The presence of a crack weakens the biscuit and strength, as measured by breakage force falls almost linearly with crack length and crack depth. The orientation of the crack, whether radial or tangential, and its location (i.e. position of the crack mid-point on the biscuit surface) are also important. Deep, radial, cracks located close to the biscuit centre can reduce the strength by up to 50%. Two separate failure criteria were examined for sound and cracked biscuits respectively. The results from these tests were in good accord with theory. For a biscuit without defects, breakage occurred when maximum biscuit stress reached or exceeded the failure stress of 420 kPa. For a biscuit with cracks, breakage occurred as above or alternatively when its critical stress intensity factor of 18 kPam0.5 was reached.

Min/max autocorrelation factor analysis (MAFA) and dynamic factor analysis (DFA) are complementary techniques for analysing short (> 15-25 y), non-stationary, multivariate data sets. We illustrate the two techniques using catch rate (cpue) time-series (1982-2001) for 17 species caught during trawl surveys off Mauritania, with the NAO index, an upwelling index, sea surface temperature, and an index of fishing effort as explanatory variables. Both techniques gave coherent results, the most important common trend being a decrease in cpue during the latter half of the time-series, and the next important being an increase during the first half. A DFA model with SST and UPW as explanatory variables and two common trends gave good fits to most of the cpue time-series. (c) 2004 International Council for the Exploration of the Sea.

Antecedentes: Los trastornos musculo-esqueléticos son una de las primeras causas de ausentismo laboral y afectan con mayor frecuencia columna y miembros. El personal de enfermería está expuesto a riesgo biomecánico superior dado por la manipulación manual de pacientes. Estimar la magnitud de asociación entre dolor osteo-muscular y carga biomecánica por movilización de pacientes en personal de enfermería y, los factores que modifican tal efecto, es de gran importancia en el ámbito laboral en busca de estrategias de prevención de enfermedades de origen laboral. Objetivo: determinar los factores predictores de dolor osteo-muscular en trabajadores de enfermería en un centro hospitalario de alta complejidad. Materiales y métodos: Estudio analítico transversal, en el que participaron 141 personas, quienes otorgaron su consentimiento informado. Los criterios de inclusión fueron: edad≥ 18 años, estudiantes, practicantes, auxiliares y jefes de enfermería asistenciales de salas de cirugía y hospitalización, antigüedad mínima de 2 meses en el cargo. Se utilizaron como criterios de exclusión: personal de enfermería en cargos administrativos y de las áreas de urgencias y cuidados intensivos, trabajadores con diagnóstico establecido artrosis, osteoartritis o artritis reumatoide, mujeres gestantes. Para lograr los objetivos aplicó el Cuestionario Nórdico, el cuestionario internacional de actividad física IPAQ y la metodología MAPO. Resultados: La frecuencia global de dolor osteo-muscular en el último año fue de 55%, implicando más frecuentemente columna lumbar, columna dorsal y miembro superior. Se evaluaron los servicios de onco-hematología, hospitalización y salas de cirugía y las clasificaciones de MAPO fueron medio a alto, no hubo áreas con riesgo irrelevante. Mediante análisis de regresión logística multivariada, se pudo determinar que los principales predictores de dolor osteo-muscular son trabajar en un área con MAPO nivel alto (OR=2,236, con respecto a MAPO medio) y en el turno de la mañana (OR=2,355, con respecto a turno en la tarde/noche).
