Determinants of Public Acceptance of the COVID-19 Vaccine: A Systematic Review

Background: The coronavirus disease 2019 (COVID-19) pandemic can be considered as a global unity that has forced all countries to work together to treat it. Consistent with ongoing efforts to reduce the prevalence of COVID-19, building a safe and effective vaccine against COVID-19, which is recognized as a major achievement, is a priority for many developed countries around the world. In this regard, we aimed to investigate the determinants of public acceptance of COVID-19 vaccine.Methods: In this review, published articles on the determinants of public acceptance of COVID-19 vaccine during 2020-2021 were reviewed. To obtain related scientific documents, the following keywords were searched in the title and abstract of published articles: Coronavirus 2019, COVID-19, and Vaccine acceptance, Resistance, Doubt, Vaccination, Determinants and Pandemics. Scientific databases such as Google Scholar, PubMed, Science Direct, Scopus and ProQuest were searched and all relevant English articles were listed. The PRISMA checklist was used to review and control the quality of articles.Results: Initially, 372 English articles were retrieved and finally 19 articles were finally selected for comprehensive review and data extraction. The results showed that most people were more receptive to vaccines that produce 90%-95% efficacy and safety levels. Also, being a woman, low age, low-income level, being single, low education and lack of trust in the government were among the factors that reduced the acceptance of people for the COVID-19 vaccine. The most common reasons for people not participating in the vaccination process were fear of vaccine side effects, lack of confidence in vaccine efficacy, and safety levels.Conclusion: Considering that a significant number of people in the world have a high acceptance of vaccines with 90%-95% safety levels. Measures need to be taken to speed up the vaccination process. Also, since most people are only afraid and anxious about the side effects caused by vaccines, it is necessary to increase people’s awareness and knowledge about the positive and negative consequences of vaccination

Health related quality of life among adolescents with premenstrual disorders: a cross sectional study

<p>Abstract</p> <p>Background</p> <p>Premenstrual disorders usually refer to premenstrual syndrome (PMS) and premenstrual dysphoric disorder (PMDD). This study was designed to evaluate health-related quality of life (HRQOL) in a sample of Iranian adolescents with premenstrual disorders.</p> <p>Methods</p> <p>This was a cross sectional study. A sample of adolescent schoolgirls aged between 14 and 19 years were included in the study. Premenstrual disorders were indicated according to the International Classification of Diseases (ICD-10) and the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV). Health-related quality of life was measured using the Short Form Health Survey (SF-36). The data were analyzed in a descriptive fashion and were compared among subgroups of the study sample.</p> <p>Results</p> <p>In all 602 female students were studied. All students reported at least one premenstrual symptom. Of these, 224 (37.2%) met the diagnostic criteria for premenstrual dysphoric disorder (PMDD). Comparing the SF-36 scores between female students with and without PMDD, it was found that there were significant differences between these two groups in all measures (P < 0.001) except for physical functioning (P = 0.274). These differences were more evident on role emotional, role physical, social functioning and bodily pain.</p> <p>Conclusion</p> <p>The study findings affirm the fact that adolescents with premenstrual disorders suffer from poor health-related quality of life. In order to improve quality of life in female adolescents appropriate support should be provided for this population especially for those who suffer from more severe premenstrual disorders.</p

Proof of Concept for the Autobiographical Memory Flexibility (MemFlex) Intervention for Posttraumatic Stress Disorder.

Autobiographical memory distortions are a key feature of posttraumatic stress disorder (PTSD). In this proof-of-concept randomized controlled trial (N = 43), we evaluated an autobiographical memory flexibility intervention, MemFlex. We aimed to determine whether the mechanism-focused intervention, which aims to improve autobiographical memory processes, may also affect other cognitive predictors of PTSD and potentially reduce PTSD symptoms in Iranian trauma survivors diagnosed with PTSD. Results indicated significant, moderate to large between-groups effect sizes in favor of MemFlex, relative to wait-list control, for the targeted cognitive mechanism of autobiographical memory flexibility and PTSD symptoms. A large, significant effect was also observed on maladaptive posttraumatic cognitions-a strong predictor of PTSD prognosis, which is a key target of high-intensity cognitive therapies for PTSD. Findings support future completion of a scaled-up trial to evaluate treatment efficacy of MemFlex for PTSD to determine whether MemFlex may offer a culturally adaptive, low-cost, low-intensity intervention able to improve cognitive mechanisms of PTSD

Impaired Autobiographical Memory Flexibility in Iranian Trauma Survivors With Posttraumatic Stress Disorder

Reduced ability to retrieve specific autobiographical memories is a well-defined feature of posttraumatic stress disorder (PTSD), and science-driven interventions have emerged to improve memory specificity and thereby symptoms. However, research in depressed samples indicates that the ability to flexibly move between retrieval of specific and general memory types (i.e., memory flexibility) may more accurately conceptualize autobiographical memory deficits in emotional disturbance. In this study, we evaluated memory specificity and memory flexibility in Iranian trauma survivors (N = 63) with and without PTSD relative to community control participants. Trauma-exposed participants had experienced a serious road-traffic accident. Results indicated that individuals with PTSD experienced reduced memory specificity and memory flexibility relative to trauma-exposed participants and community control participants. A small sample size limits the strength of conclusions, although good statistical power was obtained. Findings suggest that reduced memory flexibility may be a transdiagnostic marker of emotional disturbance and support further development of memory flexibility interventions for PTSD

Validity and reliability of the multidimensional health locus of control scale for college students

<p>Abstract</p> <p>Background</p> <p>The purpose of the present study was to assess the validity and reliability of Form A of Multidimensional Health Locus of Control scales in Iran. Health locus of control is one of the most widely measured parameters of health belief for the planning of health education programs.</p> <p>Methods</p> <p>496 university students participated in this study. The reliability coefficients were calculated in three different methods: test-retest, parallel forms and Cronbach alpha. In order to survey validity of the scale we used three methods including content validity, concurrent validity and construct validity.</p> <p>Results</p> <p>We established the content validity of the Persian translation by translating (and then back-translating) each item from the English version into the Persian version. The concurrent validity of the questionnaire, as measured by Levenson's IPC scale was .57 (P < .001), .49 (P < .01) and .53 (P < .001) for IPC, respectively. Exploratory principal components analysis supported a three-factor structure that items loading adequately on each factor. Moreover, the approximate orthogonal of the dimensions were obtained through correlation analyses. In addition, the reliability results were acceptable, too.</p> <p>Conclusion</p> <p>The results showed that the reliability and validity of Persian Form A of MHLC was acceptable and respectable and is suggested as an applicable criterion for similar studies in Iran.</p

Understanding family dynamics in a cross-cultural sample: a multi-national study

The Family Systems Circumplex Model posits that balanced levels of cohesion and adaptability are associated with positive familial outcomes, whereas extremely high or low levels of these factors are associated with deleterious outcomes. Despite the popularity and utility of this model in Western cultures, there is a dearth of empirical data supporting its use in more culturally diverse contexts. The current, preregistered study assessed the Family Circumplex Model, cultural factors, and emerging adult outcomes across seven countries (i.e., China, Iran, Nigeria, Switzerland, Turkey, the United Kingdom, and the United States). Participants were N = 3,593 emerging adults, mostly self-identifying as women (71.3%). Collaborators were participants in Psi Chi’s Network for International Collaborative Exchange (NICE) and administered measures related to family dynamics and cultural orientation to participants in a random order. Results indicated that the Family Circumplex Model did not fit cross-culturally. As such, a new model was adapted, the Expanded Circumplex Model, which demonstrated invariance across samples and between women and men. The Expanded Circumplex Model retained 6 constructs with differences regarding the separation of disengagement into 2 variables and the combining of adaptive flexibility and cohesion. The current study suggests that the cultural context in which family dynamics occur should be taken into consideration when conceptualizing family dynamics theory and measurement. Future work should seek to replicate and further apply the Expanded Circumplex Model to familial outcomes
