"Why rush to get vaccinated earlier?": Regulatory focus and COVID-19 vaccination

OBJECTIVES

The health psychology literature has paid little attention to individuals' intention to vaccinate earlier. Building on regulatory focus theory, which proposes two distinct self-regulatory foci: promotion and prevention focus (Higgins, 1997), the present study tests whether, how, and why regulatory focus contributes to the intention to vaccinate earlier (IVE) and whether IVE predicts actual behavior.

METHOD

This study used a longitudinal design with data collected at two-time points (3.5 months apart). At Time 1, 487 unvaccinated participants completed a survey assessing regulatory focus, ideal and ought reason for IVE (i.e., hopes/wishes and felt obligation/pressure regarding earlier vaccination, respectively), and IVE through leftover vaccines-vaccines that become available due to last-minute vaccination appointment cancellations. At Time 2, 364 participants reported on the attempts they made to get a leftover vaccine, whether they were vaccinated, and if so, the vaccination type (general vs. leftover vaccine), along with the date of vaccination.

RESULTS

A promotion focus was associated with IVE via ideal reason (β = .141, 95% confidence interval, CI [.085, .198]), whereas a prevention focus was associated with IVE via ought reason (β = .031, 95% CI [.012, .057]). Furthermore, both the promotion focus (β = .029, 95% CI [.016, .050]) and prevention focus paths (β = .006, 95% CI [.001, .015]) extended to vaccinating via leftover vaccines.

CONCLUSIONS

The present study illuminates how regulatory focus, especially promotion focus, can be a predictor of earlier vaccination. Our findings suggest that promotion-focused messages highlighting desirable outcomes of vaccination may help encourage earlier vaccination.

Post COVID-19, still wear a face mask? Self-perceived facial attractiveness reduces mask-wearing intention

With the emerging post-COVID era, wearing face masks has become a domain of personal choice. Then, who wants to continue wearing a mask when it is no longer mandatory? In this article, we expect and examine the role of self-perceived facial attractiveness in predicting mask-wearing intention and its mechanism across three studies (total N = 1,030). Studies 1 and 2 demonstrated that individuals with high (vs. low) self-perceived attractiveness were less willing to wear a mask, due to a weaker endorsement of the belief that mask-wearing enhances their perceived attractiveness (i.e., mask attractiveness belief). Study 3 further revealed that this mediational association was stronger in situations where the need to deliver a favorable impression was high (job interview context) versus low (walking a dog context). Overall, we provide a novel finding that self-perceived attractiveness has significant effects on mask-wearing intention via mask attractiveness belief in the post-pandemic of COVID-19. Our findings suggest that mask-wearing can shift from being a self-protection measure during the COVID-19 pandemic to a self-presentation tactic in the post-pandemic era.

Preparation and characterization of gatifloxacin-loaded alginate/poly (vinyl alcohol) electrospun nanofibers

The aim of this study was to develop novel biomedicated electrospun nanofibers for controlled release. Pre-formulation studies were carried out for nanofibers of sodium alginate (SA) (2 wt %)/polyvinyl alcohol (PVA) (10 wt %) composites (2/8, 3/7 and 4/6), by an electrospinning technique. The morphology and average diameter of the nanofibers were investigated by scanning electron microscopy (SEM). The optimum ratio (3/7) was used to load gatifloxacin hydrochloride (GH) (1wt %), found to form smooth fibers with uniform structures. The drug entrapment in the composite nanofibers was confirmed by SEM, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), thermo gravimetric analysis (TGA), differential scanning calorimetry (DSC), and swelling behavior. The drug release behavior was investigated using phosphate-buffered saline (PBS) (pH 7.4) at 37°C for 24 h. The XRD and FTIR data demonstrate that there are good interactions between PVA and SA, possibly caused by hydrogen bonds. As much as 90% of the GH was released from the electrospun fibers within 6 h of incubation. Beyond this, the release was sustained for 24 h. The thickness of nanofibers greatly influenced the initial release and rate of drug release. Moreover, GH-loaded sodium alginate/PVA composite nanofibers exhibited a useful and convenient method for electrospinning in order to control the rate and period of drug release in wound-healing applications.
