The Portuguese observatory on occupational psychosocial factors: contribution for public health
To achieve the goal of sustainable employment, considering
the profile of the Portuguese working population (PWP), is
needed a range of strategies to ensure long, productive, and
sustainable careers allied with a better quality of working life,
health, and wellbeing, but also with public health policies
grounded on scientifically validated and reliable data. This is
possible through a comprehensive working system approach
that ensures workers will be mentally and physically able to
remain at work by the balance between work demands and
individual resources allied with public health policies transfer
into the workplaces by organizations’ leadership and policy
makers. The Portuguese Observatory on Occupational Factors
(Popsy@Work) aims at addressing this global challenge by: i)
digitally collecting psychosocial data on the PWP; ii)
implementing and strengthening of a psychosocial occupational
health surveillance digital system; iii) providing
reference values for the PWP concerning Psychosocial
Health; iv) Transferring to society knowledge and best
practices; v) Raising awareness on the importance of
psychosocial management in occupational settings based on
science. Popsy@work is a digital platform that collects and
aggregates psychosocial data analytically and creates a
visualization hub adding value to data on the PWP and
giving science back to society in a usable way, empowering
workers, strengthening organizations and grounding public
policies. Pospy@Work considers the development of strategic
intelligence on levels and inequalities of psychosocial health
and well-being in occupational settings by robust metrics and
reference data. Creating opportunities for national policy
dialogue on inequalities, including the psychosocial health of
the PWP through collaboration with diverse sectors identifying
and mapping subgroups of populations whose unmet needs
require specific outreach measures
Event-related potentials modulated by the perception of sexual dimorphism : the influence of attractiveness and sex of faces
This work was supported by Fundação para a Ciência e a Tecnologia and Programa Operacional de Potencial Humano/Fundo Social Europeu [Grant reference SFRH/BD/77592/2011 to M. L. C.].Sexual dimorphism has been proposed as one of the facial traits to have evolved through sexual selection and to affect attractiveness perception. Even with numerous studies documenting its effect on attractiveness and mate choice, the neurophysiological correlates of the perception of sexual dimorphism are not yet fully understood. In the present study, event-related potentials (ERPs) were recorded during visualisation of faces that had been previously transformed in shape to appear more masculine or more feminine. The participants’ task consisted of judging the attractiveness of half of the total number of faces, and performing a sex discrimination task on the other half. Both early and late potentials were modulated by the sex of faces, whereas the effect of the sexually dimorphic transform was mainly visible in the P2 (positive deflection around 200 ms after stimulus onset), EPN (early posterior negativity) and LPP (late positive potentials) components. There was an effect of sexual dimorphism on P2 and EPN amplitudes when female participants visualised male faces, which may indicate that masculinity is particularly attended to when viewing opposite sex members. Also, ERP results seem to support the idea of sex differences in social categorisation decisions regarding faces, although differences were not evident on behavioural results. In general, these findings contribute to a better understanding of how humans perceive sexually dimorphic characteristics in other individuals’ faces and how they affect attractiveness judgements.PostprintPeer reviewe
The Portuguese Third Version of the Copenhagen Psychosocial Questionnaire: Preliminary Validation Studies of the Middle Version among Municipal and Healthcare Workers
A third version of the Copenhagen Psychosocial Questionnaire (COPSOQ III) was developed
internationally aiming to respond to new trends in working conditions, theoretical concepts,
and international experience. This article aims to present the preliminary validation studies for the Portuguese middle version of COPSOQ III. This is an exploratory cross-sectional study viewing the cross-cultural adaption of COPSOQ III to Portugal, ensuring the contents and face validity and performing field-testing in order to reduce the number of items and to obtain insight into the data structure, through classic test theory and item response theory approaches. The qualitative study encompassed 29 participants and the quantitative one 659 participants from municipalities and healthcare settings. Content analysis suggested that minor re-wording could improve the face validity of items, while a reduced version, with 85 items, shows psychometric stability, achieving good internal consistency in all subscales. The COPSOQ III Portuguese middle version proved to be a valid preliminary version for future validation studies with various populations, able to be used in correlational studies with other dimensions

The other side of recovery: validation of the Portuguese version of the subjective experiences of psychosis scale.
BACKGROUND:
The aim of this study was to develop and validate a Portuguese version of The Subjective Experiences of Psychosis Scale (SEPS) for use in Portuguese-speaking populations in order to provide a self-report instrument to assess and monitor dimensions of psychotic experiences, translating patient's perspective and experience in terms of recovery from psychosis.
METHODS:
The sample consisted of 30 participants with psychotic disorders who had recently experienced delusions or hallucinations. The SEPS was completed along with other observer-based assessments and self-report questionnaires, such as the Brief Psychiatric Rating Scale, the Insight and Treatment Attitudes Questionnaire and the Function Assessment Short Test.
RESULTS:
Two main factors representing the positive and negative components of each subscale were identified. We obtained good internal consistency and test-retest reliability for the positive and negative components of all subscales. The subscales of SEPS correlated with observer-based assessments and self-report questionnaires.
CONCLUSIONS:
The Portuguese version of the SEPS is a useful tool in the assessment and monitoring of psychotic symptoms
Organic solvents alter photophysiological and oxidative stress profiles of the coral Zoanthus sp. - towards an optimization of ecotoxicological protocols
Coral reefs are declining, affected by climate change and escalating anthropogenic pressures, such as pollution or habitat alteration. Consequently, ecotoxicological assays with tropical corals have increased, specifically towards the study of emergent or persistent pollutants. However, standardized methodology to test for corals is non-existent, and their response to organic solvents, recurrently required in ecotoxicological appraisals, remains unknown. Therefore, we aimed to establish a threshold for the safe use of the selected solvents in ecotoxicological studies with these organisms. We assessed the oxidative stress response (antioxidant response and oxidative damage), cellular energy allocation and photophysiology of the photosynthetic coral Zoanthus sp. (Anthozoa, Hexacorallia) exposed to six doses of three different organic solvents (ethanol, methanol and dimethyl sulfoxide - DMSO). Our results suggest that the coral is more sensitive to methanol and DMSO than to ethanol. Methanol and DMSO LOEC were 0.01 mL L-1 affecting maximum quantum yield (Fv/Fm) and glutathione S-transferase (GST) activity, respectively, while for ethanol was 0.03 mL L-1, influencing Fv/Fm. Despite the higher tolerance of Zoanthus sp. to ethanol, 2.9 mL L-1 of this organic solvent was the only treatment causing mortality. Based on these findings, thresholds for the use of organic solvents with tropical corals can now be adopted. Nevertheless, species specificities should not be overlooked.publishe
