Unlike conventional regression, QR examines relationships across different quantiles of the data distribution, revealing complex dynamics and offering robustness to non-normality and heteroscedasticity. We demonstrate its utility through a practical example, analysing the relationship between age and life satisfaction, supported by annotated R code. The tutorial emphasises grounding QR in a sound theoretical framework and introduces the quantile loss approach as an alternative to <i>p</i> value interpretation.

Some studies suggested that measures may not be stable after the onset of the pandemic. We examine invariance parameters, the factorial structure and variability of wellbeing variables (life satisfaction, pandemic worries, anxiety and depression screenings) across five different cultural contexts from 2020 to 2022 (<i>N</i> = 4387, total observations = 13,161). A three-factor model separating life satisfaction, worry and distress performed best in terms of model fit and parsimony. We observed scalar invariance across times and identified little variability of wellbeing measures during the pandemic, suggesting that wellbeing levels remained stable during the pandemic in each of the countries sampled. In contrast, we only identified metric invariance across countries at each time point, and found a weakening of correlations between life satisfaction and a depressive/anxious symptoms scale in lower income countries.

This is a problem because measurement quality is crucial for appropriate statistical inferences in studies using multi-item scales. Using 12 samples of the Dirty Dozen questionnaire to assess the dark triad personality, we illustrate (and provide the R scripts for) two methods to meta-analytically assess the factor structure of a scale depending on the data that is available. Further, we provide R scripts for several other methods that we do not discuss in this article in depth. We also illustrate the Reliability Generalization method to meta-analytically assess the reliability of a scale. Strengths and limitations of the different methods are discussed, together with some consideration that researchers must take into account to implement and interpret all methods here.

The results indicated that the optimal description of the network structure involved four communities: the Dark Triad traits, emotion recognition abilities as aspects of cognitive empathy, emotional intelligence traits and empathy and appraisal and expression of emotion in others as mainly traits of empathy focusing on others. Psychopathy and narcissism are central components connecting their Dark Triad community with emotional functioning communities. Psychopathy's main role stemmed from its negative relationship with emotional reactivity and recognising positive states, indicating emotional deficits in both trait and ability domains. On the other hand, narcissism had a positive relationship with the use of emotion to facilitate performance, but showed a negative relationship with recognising negative states, indicating a discrepancy between self-image and objective abilities. Machiavellianism showed weak relationships with emotional intelligence and empathy traits, but a non-significant one with the ability to recognise emotional states.

In societies with greater economic inequality, climate change inaction was more prevalent compared to those with lower economic inequality. Notably, these relations were mediated by climate change perception and moderated by climate change discussion and responsibility attribution, respectively.

Therefore, we examined the temporal asymmetry of admiration and malicious envy among Chinese adolescents. We conducted five experiments: Actual events from a self-perspective (Experiment 1; <i>N</i> = 76), hypothetical events from a self-perspective (Experiment 2; <i>N</i> = 74), time travel from a self-perspective (Experiment 3; <i>N</i> = 96), forced-choice from a self-perspective (Experiment 4; <i>N</i> = 94) and forced-choice from an other-perspective (Experiment 5; <i>N</i> = 164). The results showed that admiration exhibited a past bias, with retrospection eliciting stronger admiration than anticipation. In contrast, malicious envy exhibited different patterns of temporal asymmetry. When the threat of future negative events was high, malicious envy exhibited a future bias; however, as this threat weakened, it shifted toward a past bias. These findings provide insights into the boundary effects of temporal emotion asymmetry.
