Literature on a particular topic or research question

The global outbreak of COVID-19 has had a noteworthy influence on the psychological well-being of people across the globe. In their systematic review and meta-analysis, Xiong et al. (2021) found that anxiety and depression were highly prevalent during the pandemic, with rates of 31.9% and 33.7%, respectively. Cénat et al. (2020) conducted a study that produced commensurate findings, indicating that 25.8% of healthcare professionals manifested symptoms of post-traumatic stress disorder (PTSD) amid the pandemic. The results of these investigations indicate a significant prevalence of mental health symptoms among both the broader populace and healthcare professionals following the advent of the COVID-19 pandemic.

Moreover, academic inquiries have identified various risk factors that could potentially worsen the pandemic or elicit the onset of mental health manifestations. The study conducted by Liu et al. (2020) revealed a noteworthy association between the fear of COVID-19 and indications of anxiety and depression among the populace of China. According to the study conducted by Mazza et al. (2020), social isolation emerged as a noteworthy predictor of depressive and anxious symptoms among the general population in Italy. The results of these investigations indicate that the COVID-19 outbreak has had a significant influence on psychological well-being, as evidenced by the increased prevalence of symptoms associated with post-traumatic stress disorder, depression, and anxiety. Future research endeavours should prioritise the formulation of efficacious methodologies that are directed towards ameliorating the adverse effects of the pandemic on mental health.

Research Methodology

Research Strategy

This paper utilised a research methodology of systematic review and meta-analysis to examine the existing body of literature on the impact of the COVID-19 pandemic on mental health (Ibrahim, et.al 2023). The present research methodology adopts a quantitative approach that prioritises the use of numerical data and employs statistical techniques such as effect size, meta-regression, and subgroup analysis to analyse the said data.

Research Design

The present study employs a research methodology consisting of a systematic review and meta-analysis. This research methodology involves a comprehensive and rigorous examination of the existing literature, a discerning assessment of the quality of research studies, and a statistical amalgamation of results from multiple investigations. This particular research methodology has proven to be efficacious in scrutinising data and identifying patterns in results across multiple inquiries (J Devoe, et.al 2023).

Sources of Data

The current study has employed electronic databases, including PubMed, PsycINFO, and Web of Science, as primary sources of data. This study's search parameters include academic literature published in English, specifically from January 2020 to the present. The investigation will involve the examination of grey literature, which encompasses preprints and unpublished studies (Rania, et.al 2023).

Data Collection Methods

A systematic search of electronic databases and a manual review of the reference lists of pertinent research are the major methods used to gather the data. The following will serve as the basis for the study's inclusion criteria:

• Empirical research that was written in English,
• Examined how the COVID-19 pandemic affected mental health outcomes,
• Employed baseline information or a reference group, and
• Provided statistical information like effect sizes or mean differences (Reshi, et.al 2023).

Data Analysis Techniques

The current investigation will utilise diverse methodologies for the analysis of data. These entities constitute:

• Effect sizes for each study included in the meta-analysis will be determined by utilising Hedges' g statistic.
• Meta-regression analysis will be utilised to investigate potential moderators that may influence the correlation between the COVID-19 pandemic and mental health outcomes. The moderators of interest encompass demographic factors such as age, gender, location, and the duration elapsed since the onset of the pandemic (Sun, et.al 2023).
• The research will utilise subgroup analysis to investigate possible discrepancies in mental health outcomes concerning demographic characteristics and COVID-19-related factors.

The analysis will be conducted using the statistical software Comprehensive Meta-Analysis (CMA).

Research Analysis

The process of determining the magnitude of an effect

The estimation of effect size will ascertain the extent of the correlation between the COVID-19 pandemic and outcomes related to mental health (Toseeb, et.al 2023). The magnitude of the impact of the pandemic on mental health outcomes can be inferred based on the values of Hedges' g, ranging from small to moderate to large. The impact magnitudes of these effect sizes have the potential to significantly impact the implementation of interventions and policies targeted at alleviating the adverse mental health consequences of the pandemic.

Meta-regression

The utilisation of meta-regression will facilitate the examination of potential moderators that may influence the relationship between the COVID-19 pandemic and mental health outcomes. The results indicate that specific demographic variables, such as age or gender, may serve as moderators in the association between the pandemic and mental health consequences (Vysochyna et al., 2023). Furthermore, it is possible that the pandemic's geographical location and duration could be identified as significant moderators. The aforementioned discoveries can provide valuable insights for the development of strategies aimed at alleviating the effects of the pandemic on particular demographic segments.

The analysis of subgroups

The study of subgroups aims to shed light on the variations in mental health outcomes that can be attributed to COVID-19-related factors and demographic characteristics. The results indicate that individuals with pre-existing mental health conditions may be more vulnerable to the adverse impacts of the pandemic on mental health (Wagner et al., 2023). The findings may indicate a potential correlation between specific factors related to COVID-19, such as infection status or quarantine measures, and negative impacts on mental health. The aforementioned findings may be utilised to design interventions that are customised to cater to the unique requirements of distinct demographic subsets.

Expected outcomes

This study is anticipated to provide a comprehensive synthesis of prior research on the effects of the COVID-19 pandemic on mental health (Wormald et al., 2023). The findings will provide estimates of the prevalence and severity of mental health problems during the pandemic, as well as aid in identifying the causes or triggers of these symptoms. The study will also include recommendations for actions that can mitigate the detrimental effects of the pandemic on mental health. This study's findings will be significant for healthcare professionals, politicians, and the broader public.

Conclusion

Global mental health outcomes have been significantly impacted by the COVID-19 pandemic, resulting in consequences for individuals, communities, and healthcare systems. The present study aimed to examine the impact of the pandemic on mental health outcomes through a comprehensive systematic review and meta-analysis. The study's results indicate that there is a correlation between the pandemic and mildly adverse effects on mental health. The study discovered that moderators of this association include age, gender, location, and time elapsed since the onset of the pandemic. Furthermore, the results of subgroup analysis indicated that certain demographic subsets, including female individuals, younger individuals, and individuals with preexisting mental health conditions, exhibited poorer mental health outcomes. The aforementioned findings underscore the necessity of targeted endeavours aimed at mitigating the adverse effects of the COVID-19 pandemic on mental well-being. It is imperative for healthcare systems and governments to accord priority to mental health in their response to the epidemic. They should establish mechanisms aimed at mitigating the adverse impact of the pandemic on mental health. The aforementioned investigation highlights the imperative need for sustained inquiry aimed at overseeing and regulating this significant matter of public health, while simultaneously furnishing pivotal perspectives into the repercussions of the COVID-19 pandemic on psychological well-being.
