Virtuality is noticeably present in organisations and influences the way people interact within teams. This study involved 104 organisational teams with some degree of virtuality and intends to analyze a moderated-mediation model in which virtuality moderates the indirect effect of team conflict on team effectiveness and innovation through team trust. First, results reveal that the negative association between conflict and team trust was significant for task conflict only in teams with low virtuality, and for relationship conflict was significant under low and moderate levels of virtuality. Finally, findings indicate that virtuality moderated the negative mediated relationship between both task and relationship team conflict and team effectiveness only through cognitive trust. Overall, the findings suggest that virtuality may protect team trust from the negative effects of conflict, and they point to the key role of cognitive trust as an antecedent of team effectiveness in hybrid teams.

The main purpose of the present research was to analyze the relationship between team psychological capital and innovation, considering team learning as a mediating variable. A field survey was carried out, which included 124 work teams belonging to organizations from different sectors of activity. Hypotheses were tested through PROCESS. Results supported a direct positive relationship between team psychological capital and team innovation and an indirect influence of team psychological capital on team innovation, through team learning. The findings of this study highlight the role of team learning as an intervening process between team psychological capital and team innovation. Accordingly, managers should seek to develop team psychological capital and learning behaviors among their teams to promote innovation.

The aim of this study is to adapt and validate the Individual Work Performance Questionnaire (IWPQ) to a Portuguese version (IWPQ-PT) and to evaluate its psychometric properties in a sample of 423 digital sector workers. Two studies were conducted to define the factorial structure. In study 1 (n = 162), the results of an exploratory factor analysis pointed to a three-factor structure (18 items), explaining 55.56% of the variance. In study 2 (n = 261), the results of a confirmatory factor analysis revealed a good model fit (CFI = 0.95; RMSEA = 0.06), also reproducing the structure of the original model. The overall scale and subscales demonstrated good reliability, with Cronbach’s alpha coefficients ranging from 0.72 to 0.88. Correlations between the IWPQ-PT subscales and other instruments revealed that higher task and contextual performance are associated with increased job satisfaction, work engagement, and decreased turnover intention. Conversely, counterproductive work behavior is associated with lower job satisfaction, work engagement, and higher turnover intention. This study underscores the contributions of the IWPQ-PT as a reliable and valid tool for assessing individual work performance in Portuguese organizations and highlights its contributions to the field of employee work performance research as well as human resources practices.

This cross-sectional study tested the effects of perceived interparental conflict on emerging adults’ depressive symptomatology as mediated by aggressive attitudes. The sample included 520 college students (58.1% females) aged 18–22 years old. Total, direct and indirect effects were calculated through the estimation of an OLS regression-based mediation model, controlling for gender. The results suggest that perceptions of interparental conflict and appraisals of threat and self-blame positively predict depressive symptoms. Also, the results indicate that (1) verbal aggressive attitudes negatively mediate the relationship between interparental conflict properties and depressive symptoms; (2) hostile attitudes positively mediate the association between both threat and self-blame appraisals and depressive symptoms; and (3) anger positively mediates the relationship between both interparental conflict properties and threat appraisal and depressive symptoms. Results are discussed in the context of emerging adults’ mental adjustment and aggression expression when dealing with interparental conflict.

Empowerment is usually defined as a process of promoting the sense of competence and control as a means of capacitating individuals to improve their life conditions. The aim of this study was to describe the psychometric qualities of the Portuguese Rheumatic Disease Empowerment Scale (P-RES-8), an 8-item measure of empowerment for patients with rheumatic disease. The study enrolled 81 patients with rheumatic diseases. Participants filled in the P-RES-8, the Portuguese validated version of the Medical Outcomes Survey Short Form-36 (MOS SF-36), and a questionnaire including sociodemographic data and disease-related variables. To evaluate the dimensionality of the P-RES-8 scale, an exploratory factor analysis was conducted, and its reliability was assessed by Cronbach’s α. The validity of this measure was assessed by analyzing the correlations between empowerment, quality of life, and other relevant variables (education level and illness duration). The P-RES-8 proved to be a reliable 1-dimensional measure of empowerment in patients with rheumatic disease (Cronbach’s α = 0.94). Empowerment was positively related to quality of life. Particularly, the findings showed positive associations between empowerment, assessed by the P-RES-8, and each of the 8 domains of the MOS SF-36. The associations were stronger for mental health and general health perception. The results also revealed that empowerment is positively associated with a higher education and more years after the diagnosis. The findings provide support for the adequacy of the P-RES-8 as a measure of empowerment in patients with rheumatic disease. Moreover, empowerment showed to be an important variable in the assessment of patients’ quality of life.

The purpose of this study was to explore the psychometric properties of the Portuguese version of the Child Routines Questionnaire: Preschool (CRQ:P), a parent-report measure developed to assess daily routines specific to preschool-age children. Participants included 208 parents of preschool children (Mage = 3.97 years old; SD = 0.95; 53.4% boys). Parents also completed measures of family routines (mealtimes) and children’s social skills. A confirmatory factor analysis demonstrated that the original CRQ:P five-factor structure did not fit to the data and the subsequent exploratory factor analysis suggested a three-factor solution (Daily Living, Education/Positive Attention and Discipline), accounting for 33.36% of the total variance. Cronbach’s alpha reliability was very good for the Total scale (α = .84), and acceptable-to-good for the three subscales (α range = .68 to .79). Preliminary evidence of validity was shown by weak positive correlations between children’s and family mealtime routines. Also, routines predicted children’s social skills. Differences were found in discipline routines between younger and older children. The results provide initial evidence that the Portuguese version of the CRQ:P is a promising assessment tool that can be used in clinical practice and future empirical research focused on preschool-age children’s routines.
