The COVID-19 pandemic has emerged as a worldwide public health crisis, leading to significant disruptions in societal behaviors and norms. Within the affected population, individuals with mental health disorders are considered a vulnerable group, experiencing higher infection rates and poorer outcomes. These adverse outcomes can be attributed to various factors, including inadequate adherence to vaccination and other preventive measures. To address this issue, this study aims to present the research protocol for a scoping review that will comprehensively examine the literature on the adherence of individuals with mental disorders to preventive behaviors during the COVID-19 pandemic. The scoping review will adhere to the methodological guidelines outlined by the Joanna Briggs Institute and will be reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews checklist. A comprehensive search for published literature containing original data will be conducted in the Embase, MEDLINE, PsycINFO, and Web of Science databases. The search strategy will be developed based on the Population, Concept, and Context inclusion criteria. Two authors will independently screen titles, abstracts, and full texts for inclusion and extract relevant data. The findings of the review will be presented using descriptive statistics, including tables, charts, and flow diagrams, to elucidate the key concepts of interest.

UNASSIGNED: This systematic review aimed to assess the global application of behavioral change theory and models on COVID-19 preventive behaviors.
UNASSIGNED: This systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses procedure. Databases such as PubMed/MIDLINE, Web of Science, Scopus, EMB ASE, World Health Organization libraries, and Google Scholar were used to search all published articles in the area of application of behavioral change theory and model on COVID-19 preventive behavior until October 1, 2022. Studies published in another language other than English were excluded. Two independent reviewers did the article selection and quality check. A third reviewer asked if any disagreement were found.
UNASSIGNED: Seventeen thousand four hundred thirty-six total articles were retrieved from all sources after the removal of duplicated articles and those not evaluating the outcome of interest were excluded. Finally, 82 articles done using behavioral change theory and model on COVID-19 preventive behaviors were included. The health belief model (HBM) and theory of planned behavior (TPB) were most commonly used in COVID-19 preventive behaviors. The constructs of most behavioral theories and models were significantly associated with COVID-19 preventive behaviors such as hand washing, face mask use, vaccine uptake, social isolation, self-quarantine, social distance, and use of sanitizers.
UNASSIGNED: This systematic review summarizes comprehensive evidence on the application of behavioral change theory and model on COVID-19 preventive behaviors globally. A total of seven behavioral change theories and models were included. The HBM and TPBs were most commonly used for COVID-19 preventive behaviors. Therefore, the application of behavioral change theory and models is recommended for developing behavioral change interventional strategies.
