Psychological intervention

Does psychological intervention help increase self-confidence amongst patients who are suffering from chronic diseases?
To begin the search for literature, I will first identify relevant words in the PICOT question, which are not necessarily the keywords; for example, self-confidence, suffering, chronic diseases, and psychological intervention. These words are searched in nursing-reach websites and other platforms such as PubMed (Rouleau et al., 2019). After the search was conducted, I filtered the documents to remain with the most appropriate ones and then examined and evaluated the documents to ensure that the titles selected had information concerning self-confidence in patients suffering from chronic diseases and the relevant psychological intervention.Consequently, any other documents that do not contain the information needed are dropped to improve effectiveness in the papers used.
Many taxonomies exist that are utilized to rank the strength of research evidence, such as consistency and quality of evidence, study design, systematic reviews (Rouleau et al., 2019). To determine the best evidence for the PICOT question, I will filter the study resources relevant to my PICOT and use the resources containing data on the psychological intervention that would help improve self-confidence in the identified population.
