COVID-19 pandemic worry and vaccination Intention : the mediating role of the health belief model components
(Frontiers, 2021) Iacob, Claudia Iuliana; Ionescu, Daniela
Given the negative consequences of the ongoing COVID-19 pandemic on public health, his study aimed at investigating: (1) the differences between adults with and without chronic illness in buying behavior, vaccination ntention, pandemic worry, and the health belief model (HBM) components; (2) the HBM components as mediators of the relationship between pandemic worry and vaccination intention. The sample consisted of 864 adults (66.6% females, Mage D 47.61, SD D 9.23), of which 20.5% reported having a chronic illness. Associations between pandemic worry, vaccination intention, and HBM were ascertained using correlation and mediation analyses. Individuals with chronic illness reported a higher level of pandemic worry, higher levels of perceived threat, greater benefits from vaccination, had lower self-efficacy and bought more medicine and sanitary/hygienic products. No significant differences were observed regarding vaccination intention, barriers against vaccination, and changes in food buying behavior. We found that the relationship between pandemic worry and vaccination intention was partially mediated by the perceived threat of disease and the benefits of vaccination. Pandemic worry predicted vaccination intention directly but also through the contribution of the perceived threat of disease and the benefits of vaccination. These findings suggest that presenting evidence of COVID-19 vaccine efficacy and the benefits of having the vaccine (especially for vulnerable groups, such as chronic illness patients) will encourage the population to follow vaccination recommendations.
Emotional distress related to hazards and earthquake risk perception
(Springer Nature, 2021) Ionescu, Daniela; Iacob, Claudia Iuliana; Avram, Eugen
This paper aimed to investigate emotional distress related to hazards (EDH) considering appraisals and personal resources from cognitive appraisal theory in a sample of Bucharest inhabitants periodically exposed to earthquakes (EQ). The sample consisted of 336 respondents (M = 33.71 years old, SD = 13.71, 64.6% females). The hierarchical regression model revealed that discomfort of living space, a personal resource, was the strongest predictor of EDH (β = .18, t(313) = 3.09, p < .01), closely followed by appraisals or risk perception variables: hazards anticipation (β = .17, t(316) = 2.11, p < .05) and negative EQ consequences (β = .13, t(316) = 2.28, p < .05). The overall model explained 17% of the variance of EDH. This study shows that the cognitive appraisal theory can be successfully used to explain the EDH of citizens living in an earthquake-prone city. Also, it emphasizes that earthquake-related factors can be relevant when discussing EDH levels of people in cities experiencing recurrent earthquakes.
Self-authenticity, optimism and neuroticism in relation to basic psychological needs.
(West University of Timisoara, 2019) Ionescu, Daniela; Iacob, Claudia Iuliana
This paper aimed at investigating the mediating role of one personality construct (i.e., dispositional optimism) on the relationship between self-authenticity and basic psychological needs (BPN) satisfaction. This study also aims to investigate the predictive role of three personality constructs (self-authenticity, optimism, and neuroticism) on basic psychological needs satisfaction. The participants were 566 Romanian adults from the general population (M = 43.66 years old, SD = 10.46), who were asked to fill in multiple questionnaires. Findings reveal that optimism mediates the relationship between self-authenticity and the satisfaction of the need for autonomy (β=.30, R2=.39, p<0.001) and also mediates the relationship between self-authenticity and the satisfaction of the need for competence (β=.51, R2=.36, p<0.001), but does not mediate the relationship between self-authenticity and the need for relatedness. Another result of this study is that the three personality factors (self-authenticity, optimism, and neuroticism) predict altogether the satisfaction of basic psychological needs (β= -.11, R2=.52, p<0.05). These results extend the current knowledge about personality determinants involved in autonomy, competence and relatedness basic needs from self-determination theory. In the end, the authors discuss the implications of the findings, the limits of the present study and future research suggestions.
The role of catastrophizing and basic psychological needs satisfaction on health-related quality of life and pain in patients with lumbar disc herniation
(Frontiers, 2023) Ionescu, Daniela; Iacob, Claudia Iuliana; Brehar, Felix Mircea; Avram, Eugen
Lumbar disc herniation (LDH) is one of the most common conditions associated with functional disability, affecting patients’ quality of life (QOL). Disability can be affected by cognitive factors, such as pain catastrophizing. Similarly, unfulfilled basic psychological needs (i.e., autonomy, competence, relatedness) are associated with biases in pain perception and QOL. Using the fear-avoidance model and the self-determination theory, this study investigates: (1) the separate contribution of pain-related variables and basic psychological needs satisfaction in predicting QOL in patients proposed for LDH surgery; (2) pre- and post-surgical differences in pain catastrophizing and basic psychological needs satisfaction.
