Studies indicate that there is a positive relationship between openness to experience and creativity. However, relatively little attention has been given to the mechanism of this relationship. On the basis of previous findings, we hypothesized a conceptual model and tested the mediating role of intrinsic motivation and the creative process engagement in the relationship between openness to experience and creativity. One hundred and ninety‐eight undergraduates in Malaysia participated in the study and completed an online measure of openness to new experience, creativity, intrinsic motivation, and the creative process engagement. Consistent with the hypothesis, people who scored high on openness reported high intrinsic motivation. The high motivation enhanced engagement in creativity‐related activities, which in turn, improved self‐rated creativity. The findings not only shed light on mechanisms that underlie in the openness‐creativity linkage but they also highlight the importance of intrinsic motivation and creative process engagement in the linkage. Together, the study extends the effect of personality trait on creativity and offers a new direction for future studies.

Climate change threatens mental health via increasing exposure to the social and economic disruptions created by extreme weather and large-scale climatic events, as well as through the anxiety associated with recognising the existential threat posed by the climate crisis. Considering the growing levels of climate change awareness across the world, negative emotions like anxiety and worry about climate-related risks are a potentially pervasive conduit for the adverse impacts of climate change on mental health. In this study, we examined how negative climate-related emotions relate to sleep and mental health among a diverse non-representative sample of individuals recruited from 25 countries, as well as a Norwegian nationally-representative sample. Overall, we found that negative climate-related emotions are positively associated with insomnia symptoms and negatively related to self-rated mental health in most countries. Our findings suggest that climate-related psychological stressors are significantly linked with mental health in many countries and draw attention to the need for cross-disciplinary research aimed at achieving rigorous empirical assessments of the unique challenge posed to mental health by negative emotional responses to climate change.

SUMMARY In social science research and clinical practice, and in educational settings, psychological tests/scales are being increasingly used because of their reliability and the ease and speed of gathering, comparing and differentiating data. A new scale is usually created when instruments or questionnaires to measure the construct of interest are not be readily available or if existing questionnaires do not fully satisfy requirements. Scales are also translated and revalidated if they are not in the language required. This article takes the reader through steps in developing, validating and translating tests in the field of social sciences.

Studies have found that extraversion enhances happiness indirectly through social support. However, it is unclear how social support may be connected to happiness. On the basis of a literature review, we hypothesize that individual hope may play an important role in the relationship between social support and happiness. Using a serial mediation model, the present study attempted to investigate the hypothetical mediating role of hope in the relationship between extraversion and happiness and between social support and happiness. Analysis of responses of 360 undergraduate students showed that extraversion, social support, and hope were significantly linked with happiness. Moreover, hope was found to mediate the linkage of extraversion and happiness and of social support and happiness. The results also supported the view that extraversion enhances happiness through social support and then hope (serial mediating effect). Lastly, the serial mediating effect was found to be significantly lower than the other two indirect effects. The findings offer insights into the effect of social support on happiness and extend the understanding of the relationship between extraversion and happiness.
