Literature Review Requirementshypothesis Tip First Identify Your Inde ✓ Solved
Literature Review Requirements Hypothesis tip: -First identify your independent variable (and the two levels of it that you are comparing). I encourage you to make things easy on yourself and keep it to two levels. -Second, identify your dependent variable and how you are measuring it. If you don't have a clear number coming from your dependent variable, then it's probably still too vague, so give some more thought to how you want to measure your specific DV. Some of you want to measure a bunch of things (multiple DVs), but for this proposal you only need to choose one. More DVs and IVs means more hypotheses. -Once you have those (two levels of your IV and a 1 measurable DV), then you're able to write out a testable hypothesis.
All you need to do is write out those three parts you identified in a way that is consistent with your literature acquired so far. Your hypothesis should look something like this, but with your actual variables plugged in: -(IV Group 1) will have higher/lower (dependent variable) than (IV Group 2). -The higher or lower depends on the direction of your hypothesis. Here is an example: (Those that receive cognitive behavioral therapy) will have lower (depression scores) than (those that have not received cognitive behavioral therapy). - Make sure it is a word document, text document, or PDF to make sure I can easily access it. -Intro: Clearly describe research area and its importance. Define key terms/theories. -Four or more relevant academic articles are included -The goals/hypotheses, methods, and respective conclusions of the articles are accurately described -The four articles are cited in the text and included in the reference section correctly in APA format =Conclusion summarizes overall trends/overlap/differences in the research and identifies your research direction, then identifies variables that will be explored and a testable hypothesis based on the literature.

Literature Review on Cognitive Behavioral Therapy and Depression Scores
Introduction
Cognitive Behavioral Therapy (CBT) is a psychotherapeutic approach that primarily focuses on modifying dysfunctional emotions, behaviors, and thoughts through a goal-oriented, systematic process (Beck, 2011). As a widely accepted form of psychotherapy, CBT has gained considerable attention in mental health settings, particularly for treating depressive disorders (Hofmann et al., 2012). Depression is characterized by persistent sadness, loss of interest in activities, and a range of cognitive, emotional, and behavioral changes that significantly impair daily functioning (American Psychiatric Association, 2013). Given the global prevalence and impact of depression, effective treatment methodologies remain paramount. This literature review explores the effectiveness of CBT in reducing depression scores compared to no treatment.
Literature Review
Article 1: Efficacy of CBT in Depressive Disorders
Hofmann et al. (2012) conducted a meta-analysis examining the effectiveness of CBT on depression outcomes. Their findings indicated that CBT significantly reduced depression scores as measured by standardized assessment tools, such as the Beck Depression Inventory (BDI) and the Hamilton Rating Scale for Depression (HRSD). This study established CBT as not only effective but also as a reliable short-term intervention for depression.
Article 2: Comparisons Between CBT and Pharmacotherapy
In a longitudinal study, The psychological treatment of depression: A meta-analysis (Cuijpers et al., 2014) compared counseling methods and pharmacotherapy in treating depression. The researchers revealed that participants who underwent CBT exhibited lower depression scores compared to individuals prescribed selective serotonin reuptake inhibitors (SSRIs). This suggests that while pharmacotherapy is an essential component in managing depression, CBT might lead to better or equally effective outcomes, aligning with the hypothesis that psychological treatments can produce long-lasting effects.
Article 3: Internet-based CBT
A study by Andersson et al. (2014) evaluated the efficacy of internet-based CBT for reducing depression scores, particularly among individuals who may not have access to in-person therapy. The research indicated that participants engaging with internet-based CBT reported significant reductions in depression scores over the course of the treatment. This highlights not only the versatility of CBT as a treatment modality but also its potential to reach broader audiences in need of mental health support.
Article 4: Integrative Approaches
A recent study conducted by Cuijpers et al. (2020) explored the integration of CBT with other therapeutic approaches. This research indicated that combining CBT with mindfulness interventions led to decreased depression scores over standard CBT alone. Participants who received combined treatments showed greater efficacy in managing depressive symptoms, suggesting a possible area for further exploration.
Hypothesis Development
Based on the reviewed literature, the independent variable (IV) for this study is the type of intervention, specifically:
1. Group 1: Individuals receiving Cognitive Behavioral Therapy
2. Group 2: Individuals not receiving any active treatment for depression.
The dependent variable (DV) will be the level of depressive symptoms as measured by standardized tools, specifically the Beck Depression Inventory (BDI).
The formulated hypothesis is as follows: "Individuals who receive Cognitive Behavioral Therapy will have lower depression scores than individuals who do not receive any active treatment."
Conclusion
In summary, the literature supports the effectiveness of CBT in treating depression. Several studies indicate that CBT significantly reduces depression scores compared to individuals who receive no treatment, reinforcing the hypothesis that specific therapeutic approaches yield measurable benefits for mental health conditions. The increasing digitalization of therapy provides new avenues that can expand access to effective treatments, such as internet-based CBT, further supporting the versatility and adaptability of CBT practices.
Future research should explore further integrative modalities that can potentially enhance the effectiveness of CBT in treating depression. Overall, the body of literature confirms the importance of continuing to refine and assess the efficacy of therapeutic approaches like CBT in reducing mental health symptoms.
