Effects of diagnosis threat on cognitive complaints after COVID-19.

OBJECTIVE

The term "long-COVID" refers to the persistence of neurological symptoms after being ill with COVID-19 (e.g., headaches, fatigue, and attentional impairment). Providing information about long-COVID (i.e., "diagnosis threat") increased subjective cognitive complaints among recovered COVID-19 patients compared with those exposed to neutral information (Winter & Braw, 2022). Notably, this effect was particularly prominent among more suggestible participants. Our aim in the current study was to validate these initial findings and to explore the impact of additional variables (e.g., suggestibility).

METHOD

Recovered patients (n = 270) and controls (n = 290) reported daily cognitive failures after being randomly assigned to either a diagnosis threat (exposure to an article providing information regarding long-COVID) or a control condition.

RESULTS

Recovered patients, but not controls, reported more cognitive failures in the diagnosis threat condition compared with the control condition. Diagnosis threat added significantly to the prediction of cognitive complaints based on relevant demographic variables and suggestibility. Diagnosis threat and suggestibility interacted (i.e., suggestible individuals were particularly vulnerable to the impact of a diagnosis threat).

CONCLUSIONS

Diagnosis threat may contribute to the persistence of complaints regarding cognitive impairment among recovered COVID-19 patients. Suggestibility may be an underlying mechanism that increases the impact of diagnosis threat. Other factors, such as vaccination status, may be at play though we are only at the initial stages of research concerning their impact. These may be the focus of future research, aiding in identifying risk factors for experiencing COVID-19 symptoms past the resolution of its acute phase.
