The Dynamics of Fear at the Time of Covid-19: A Contextual Behavioral Science Perspective.

COVID-19 is the relevant disease caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmitted via close contact between persons. On March 12th, 2020, WHO announced COVID-19 outbreak a pandemic, in view of its worldwide escalation. As the pandemic disease explodes, a parallel outbreak of fear and worry is also spreading. We react to fear symbolically, by arbitrarily relating it to other objects and events through derived verbal relations, so language may alter the way we experience events and consequently affects how we are functionally or dysfunctionally oriented to the world around us. In this paper we will outline the different human learning processes connected to fear responding, from the simplest type to the more complex cognitive ones, approaching them from the point of view of contextual behavioral science, a modern form of behavioral thinking. We will outline a model of intervention to foster psychological flexibility and more functional value-based actions. We will argue that in a pandemic and in the post-pandemic phase it could be a key for adapting to new and changed circumstances.

Vapourized hydrogen peroxide decontamination in a hospital setting inactivates SARS-CoV-2 and HCoV-229E without compromising filtration efficiency of unexpired N95 respirators.

BACKGROUND: The COVID-19 pandemic highlighted the need for evidence-based approaches to decontamination and reuse of N95 filtering facepiece respirators (FFRs). We sought to determine whether vapourized hydrogen peroxide (VHP) reduced SARS-CoV-2 bioburden on FFRs without compromising filtration efficiency. We also investigated coronavirus HCoV-229E as a surrogate for decontamination validation testing. METHODS: N95 FFRs were laced with SARS-CoV-2 or HCoV-229E and treated with VHP in a hospital reprocessing facility. After sterilization, viral burden was determined using viral outgrowth in a titration assay, and filtration efficiency of FFRs was tested against ATSM F2299 and NIOSH TEB-STP-APR-0059. RESULTS: Viable SARS-CoV-2 virus was not detected after VHP treatment. One replicate of the HCoV-229E laced FFRs yielded virus after processing. Unexpired N95 FFRs retained full filtration efficiency after VHP processing. Expired FFRs failed to meet design-specified filtration efficiency and therefore are unsuitable for reprocessing. DISCUSSION: In-hospital VHP is an effective decontaminant for SARS-CoV-2 on FFRs. Further, filtration efficiency of unexpired respirators is not affected by this decontamination process. CONCLUSIONS: VHP is effective in inactivating SARS-CoV-2 on FFRs without compromising filtration efficiency. HCoV-229E is a suitable surrogate for SARS-CoV-2 for disinfection studies.

Process-based functional analysis can help behavioral science step up to novel challenges: COVID - 19 as an example.

Historically speaking, the behavioral tradition advanced functional analysis as a method of applying existing principles to novel situations. In the more than half a century since that idea was advanced, functional analysis has either fallen into disuse, as in most of applied psychology, or has been used but modified to a point that is virtually inapplicable elsewhere, as in applied behavior analysis work with severe developmental disabilities. In this paper we argue that the current challenges with COVID-19 present an ideal time to reinvigorate functional analysis by combining it with the growing body of evidence on processes of change, organized under an extended evolutionary meta-model. This new form of process-based functional analysis takes advantage of the strengths of contextual behavioral science, while opening avenues of fruitful interaction with other wings of intervention and evolutionary science more generally. Using the psychological flexibility model as an example, we show how this approach solves the key problems of classical functional analysis and helps professionals deal with novel challenges such as those posed by COVID-19. Humanity is now facing an extraordinary and unexpected situation. Behavioral science needs to rise to that challenge in a way that provides both immediate practical value and greater assurance of long-term benefits for our understanding of human complexity more generally. Process-based functional analysis can be a vehicle to do just that.
