ObjectiveTo compile the information overload severity scale in the situation of coronavirus disease 2019 epidemic, and evaluate the reliability and validity.MethodsFrom February to March 2020, according to the procedures of literature analysis, semi-structured interview, and expert consultation, an initial scale was formed; and then the online scale was measured, and the scale items were screened based on the measured results of the scale. The reliability was evaluated by Cronbach’s α coefficient, and the validity was tested by exploratory factor analysis.ResultsThere were 8 items in the initial scale. The scale items were screened based on the degree of dispersion, the correlation coefficient with the total score, and the factor-load-related indicators, and finally a 7-item scale was formed. The factor analysis results of the scale showed that one component could be extracted from the scale, and the reliability analysis showed that the total Cronbach’s α coefficient of the scale was 0.863.ConclusionThe information overload severity scale has good reliability and validity, which can provide strong support for related research after the outbreak of coronavirus disease 2019 and other major public events.
Objective To explore the characteristics of cognitive impairment in patients with alcohol dependence, and analyze the related influencing factors. Methods The Montreal Cognitive Assessment Scale (MoCA) was used to evaluate the cognitive function of 65 alcohol dependent patients hospitalized between January 1st and December 31st, 2014. The features of cognitive impairment and related influencing factors were analyzed. Results The differences of MoCA attention and delayed recall between different drinking year groups had statistical significance (P<0.05). The correlations of drinking year with MoCA attention (r=–0.250,P=0.044), and with delayed recall (r=–0.326,P=0.008) were both negative. MoCA scores, naming, attention and delayed recall were different statistically among different age groups (P<0.05). The correlations of ages with MoCA scores (r=–0.429,P<0.001), naming (r=–0.261,P=0.035), attention (r=–0.391,P=0.001) and delayed recall (r=–0.461,P<0.001) were all negative. MoCA scores, the visuoconstructional skills, language, abstraction and delayed recall were significantly different among different education level groups (P<0.05). The correlations of education level with MoCA scores (rs=0.650,P<0.001), the visuoconstructional skills (rs=0.540,P<0.001), language (rs=0.486,P<0.001), abstraction (r=0.602,P<0.001) and delayed recall (rs=0.593,P<0.001) were all positive. Ages had an effect on MoCA scores by multiple linear regression analysis (P<0.01). Conclusions For alcohol dependent patients with cognitive impairment, cognitive function is correlated with drinking year, age and education level. The cognitive function is much serious in patients with older age and longer drinking years. This kind of patients should be focused on and intervened early.
