Psychometric Properties of the Oldenburg Burnout Inventory in a Portuguese Sample of Aircraft Maintenance Technicians
Funding: PhD fellowship - PP - Coordenação de Aperfeiçoamento de Pessoal de Nível Superior, Grant/Award, Number: 88887150178/2017-00.From its initial conceptualization as emotional exhaustion, cynicism, and reduced personal efficacy for the help professions, burnout has received increasing attention in modern times, especially after the 2019 WHO’s inclusion of this syndrome in the ICD-11 list. Burnout can be measured using several psychometric instruments that range in dimensionality, number of items, copyrighted, and free use formats. Here, we report the psychometric properties of data gathered with the Oldenburg Burnout Inventory (OLBI) in a sample of Portuguese Aircraft maintenance technicians. As far as we know, this is the first study addressing the burnout syndrome in this occupational group. Data gathered with the OLBI displayed good evidence of validity related to internal structure, to other variables, with good evidence of reliability. We showed that burnout significantly correlated with mental and physical fatigue emphasizing the vital critical role that these variables play with safety in the aviation industry.publishersversionpublishe
Relational Job Characteristics and Well-Being of Brazilian K-12 Teachers
A teacher’s relationship with students can be a source of more than stress. The attributes of relational jobs either promote positive (e.g., work engagement) or inhibit negative (e.g., exhaustion) psychological states that constitute potential predictors of teachers’ general well-being (e.g., health perception). The present study tests hypotheses regarding the relationships between the psychological effects of relational job characteristics and teachers’ work-related and context-free well-being indicators. Preschool, primary, and secondary Brazilian school teachers (n = 2205) responded to a cross-sectional survey. Data were analyzed by multiple mediator structural equation modeling. The psychological effects of relational job characteristics predicted exhaustion, engagement, and health perception. Findings support indirect effects on health perception of exhaustion and engagement. Data were interpreted according to the job demands-resources model, where the relational job characteristics constitute essential resources that foster work engagement, diminish burnout, and indirectly affect more generalized well-being states such as general health. Possible explanations for the relationships are discussed.info:eu-repo/semantics/publishedVersio
Impacto da saúde bucal nas dimensões física e psicossocial: uma análise através da modelagem com equações estruturais
This study aimed to estimate the prevalence of impact of oral health conditions on physical and psychosocial dimensions among adolescents and to identify factors associated with severity of impact. The impact of oral health status was assessed by the instrument Oral Health Impact Profile (OHIP-14). The covariates were: socioeconomic status, habits and health care, use of dental services, and normative conditions of oral health. Structural equation modeling was performed, and 15.6% of adolescents reported impact in at least one dimension of the OHIP-14. The dimensions that showed the highest prevalence of impact were psychological distress (11.8%) and physical pain (6.6%). The number of teeth needing dental treatment, number of filled teeth, and CPI significantly affected severity of impact. In this adolescent population, unfavorable socioeconomic conditions were associated with reduced use of dental services, associated in turn with precarious oral health conditions and increased severity of impact.El objetivo de este estudio fue evaluar el impacto de las condiciones de salud bucal en sus dimensiones físicas y psicosociales entre adolescentes. La gravedad del impacto fue tratada como variable latente, medida por medio de un cuestionario Oral Health Impact Profile (OHIP-14). Las covariables fueron: el nivel socioeconómico, los hábitos y el cuidado de la salud, utilización de servicios dentales y condiciones de salud bucal. Se realizó un modelado de ecuaciones estructurales y los modelos fueron estimados por máxima verosimilitud. El efecto del número de dientes con necesidad de tratamiento, número de dientes restaurados y el CPI de la gravedad del impacto fue significativo. En esta población, las condiciones socioeconómicas desfavorables se asocian con una menor frecuencia de uso de los servicios dentales, que están asociadas con malas condiciones de salud oral, y que a su vez se correlacionaban con una mayor gravedad del impacto.O objetivo deste estudo foi estimar a prevalência do impacto das condições de saúde bucal nas suas dimensões física e psicossocial entre adolescentes, bem como identificar os fatores associados à gravidade do impacto.

Isokinetic evaluation of knee muscles in soccer players: discriminant analysis [Avaliação isocinética dos músculos do joelho em jogadores de futebol: análise discriminante]; [Evaluación isocinética de los músculos de la rodilla en jugadores de fútbol: análisis discriminante]
Introduction:
Muscle activity in soccer players can be measured by isokinetic dynamometer, which is a reliable tool for assessing human performance.
Objectives:
To perform isokinetic analyses and to determine which variables differentiate the under-17 (U17) soccer category from the professional (PRO).
Methods:
Thirty four players were assessed (n=17 for each category). The isokinetic variables used for the knee extension-flexion analysis were: peak torque (Nm), total work (J), average power (W), angle of peak torque (deg.), agonist/ antagonist ratio (%), measured for three velocities (60°/s, 120°/s and 300°/s), with each series containing five repetitions. Three Wilks' Lambda discriminant analyses were performed, to identify which variables were more significant for the definition of each of the categories.
Results:
The discriminative variables at 60°/s in the PRO category were: extension peak torque, flexion total work, extension average power and agonist/antagonist ratio; and for the U17s were: extension total work, flexion peak torque and flexion average power. At 120°/s for the PRO category the discriminant variables were: flexion peak torque and extension average power; for the U17s they were: extension total work and flexion average power. Finally at 300°/s, the variables found in the PRO and U17 categories respectively were: extension average power and extension total work.
Conclusion:
Isokinetic variables for flexion and extension knee muscles were able to significantly discriminate between PRO and U17 soccer players.

University student engagement inventory (USEI): psychometric properties
Academic engagement describes students’ investment in academic learning and achievement and is an important indicator of
students’ adjustment to university life, particularly in the first year. A tridimensional conceptualization of academic engagement
has been accepted (behavioral, emotional and cognitive dimensions). This paper tests the dimensionality, internal consistency
reliability and invariance of the University Student Engagement Inventory (USEI) taking into consideration both gender and the
scientific area of graduation. A sample of 908 Portuguese first-year university students was considered. Good evidence of
reliability has been obtained with ordinal alpha and omega values. Confirmatory factor analysis substantiates the theoretical
dimensionality proposed (second-order latent factor), internal consistency reliability evidence indicates good values and the results
suggest measurement invariance across gender and the area of graduation. The present study enhances the role of the USEI
regarding the lack of consensus on the dimensionality and constructs delimitation of academic engagement.Jorge Sinval received funding from the William James Center for Research, Portuguese Science Foundation (FCT UID/PSI/04810/2013).

The Psychological Effects of Relational Job Characteristics Scale: An Adaptation Study for Brazilian K-12 Teachers
Relationally enriched jobs can foster psychological states, which, with respect to the beneficiaries of one’s work, drive one’s motivation. These states can be measured with the psychological effects of relational job characteristics scale, an instrument for which the validity is, at present, only supported by preliminary evidence. Accordingly, the present study’s objective was to test a set of psychometric properties reflecting the validity and reliability of the interpretations proposed for this scale. Findings drawn from a sample of 2011 K-12 Brazilian teachers suggested that a tridimensional structure with some residual covariances afforded the best fit. Given the existence of high inter-factor correlations, a second-order factor was proposed as a complementary, if not necessary, feature. Internal consistency omega and alpha coefficients attested to the scores’ reliability, and the factor structure achieved indicates invariance across public state, public municipal, and private Brazilian schools. Different relationships with prosocial motivation and work engagement were identified, suggesting validity of the scale based on relationships with other variables.info:eu-repo/semantics/publishedVersio
Practice environment scale of the nursing work index: portuguese version and psychometric properties
Aim: To assess the psychometric properties regarding the Portuguese version of the
Practice Environment Scale of the Nursing Work Index.
Background: The Practice Environment Scale of the Nursing Work Index is the most
widely used measure for assessing the practice environment. A model with a higher
number of factors appears to be more adequate to Portuguese settings.
Method: A confirmatory factor analysis was performed to the Practice Environment
Scale of the Nursing Work Index using a sample of 850 Portuguese nurses. Three
models were tested: the original model, a seven-factor
model and a higher-order
model. An analysis of invariance was performed in two subsets to confirm the stability
of the solution.
Results: The seven-factor
model fit better to the data than the original model. After
refinement, this solution showed suitability and a stable factor structure. Reliability,
convergent validity and discriminant validity were confirmed. A second-order
factor
solution also showed suitability.
Conclusion: The seven-factor
structure of the Practice Environment Scale of the
Nursing Work Index showed a better goodness-of-
fit
to Portuguese settings than the
original structure. The second-order
factor solution allows an overall assessment of
practice environments.
Implications for Nursing Management: The Portuguese version of the Practice
Environment Scale of the Nursing Work Index is a valuable tool for assessing
Portuguese nursing practice environments. The seven-factor
solution of the Practice
Environment Scale of the Nursing Work Index showed high specificity.info:eu-repo/semantics/publishedVersio
