W​‌‍‍‍‌‍‍‍‌‍‍‍‌‌‌‌‌‌‍‍​hen commencing a new research project, it is important to examine what is already known. This is crucial to formulating decisions about the focus of any studies you will go on to design and research. This assignment lays the ground work for scientific research and report writing. The first hand-in assignment which is a literature review which addresses the subject of your choosing. A literature review involves searching published studies on the topic of interest, to ensure that you have a grasp of the research that has already been conducted. This assignment requires that you carry out a comprehensive literature search to answer a question of interest agreed with your tutor. You should provide an overview of the subject under consideration and typically it should address the following points: Compare different authors’ views on an issue. Group authors who draw similar conclusions. Note areas in which authors disagree. Highlight exemplary studies. Highlight gaps in research. Show how your study relates to previous studies. Show how your study relates to the literature in general. Conclude by summarising what the literature says. There are several different reviews that take place within science. The approach for this review is the qualitative systematic review which is a method for integrating or comparing the findings from qualitative studies with the aim that the knowledge accumulated with lead to the new development of theory through an analysis of themes or constructs that may lie within individual qualitative studies. The approach differs from other types of systematic review because i​‌‍‍‍‌‍‍‍‌‍‍‍‌‌‌‌‌‌‍‍​t is not additive in nature, rather the goal is interpretive to assist a broader understanding of a construct of interest, they can be used to explore barriers, examine the uptake of services, exploring different viewpoints, and as such possesses considerable strengths in supplementing research with evidence based practice through user reported and practitioner observed considerations. The evidence from such reviews can be much more powerful than questionnaires or surveys which may isolate a construct. Opinions differ on the best methods to approach the qualitative systematic review, and this is in part because the field is still in its infancy, with some arguing that where a holistic interpretation is sought, more selective search criteria yield the most effective results, and others arguing that a more comprehensive strategy is required. A systematic review is a literature review focused on a research question. It differs from other types of review because it attempts to organise all the high-quality research identified, appraise it and synthesize the conclusions. It is systematic because it examines studies that use explicit and reproducible methods. Each research study is evaluated against explicit principles, a protocol which is laid down in advance.This means that before the review begins, the process of evaluating the papers is determined. The systematic review is becoming a key, if not mandatory, professional skill as it requires you to: Retrieve and organise information effectively. Problem solve and reason in a systematic and objective manner. Present and evaluate research findings​‌‍‍‍‌‍‍‍‌‍‍‍‌‌‌‌‌‌‍‍​.
