Research proposal. Each student needs to choose one seminar topic (or integrate more than one topic), develop and write a research proposal related with this topic, and present it. Your paper MUST conform to the guidelines of APA style (6th ed). Detailed instructions about the proposals will be posted in ItsLearning. -I uploaded an example of the proposal – Also uploaded the required guideline for the research !!! I want my research to be about the eating disorder Anorexia. It has to be detailed and specific.

Title: Investigating the Biopsychosocial Factors Influencing Anorexia Nervosa: A Research Proposal


Anorexia nervosa (AN) is a severe and potentially life-threatening eating disorder characterized by a persistent restriction of energy intake, an intense fear of gaining weight or becoming fat, and a distorted body image (American Psychiatric Association, 2013). This research proposal aims to investigate the biopsychosocial factors influencing the development and maintenance of AN. By examining these factors, we can gain a better understanding of the complex etiology of AN, which can inform the development of effective prevention and treatment strategies.

Literature Review:

Biological Factors:

Research has shown that there are several biological factors that contribute to the development and maintenance of AN. Genetic studies have identified a heritable component in AN, with estimates of heritability ranging from 28% to 74% (Bulik et al., 2007). These studies suggest that there may be specific genes involved in AN susceptibility, including those related to appetite regulation, metabolism, and neuroendocrine signaling. Additionally, neurobiological research has revealed alterations in brain regions associated with reward processing, cognitive control, and body image perception in individuals with AN (Kaye et al., 2009).

Psychological Factors:

Psychological factors play a crucial role in the development and maintenance of AN. Negative body image is a prominent feature of AN and is strongly associated with the drive for thinness and body dissatisfaction (Stice, 2002). Perfectionism is another psychological factor that has been consistently linked to AN, as individuals with AN often display a relentless pursuit of unattainable standards of thinness and perfection (Bardone-Cone et al., 2007). Additionally, distorted cognitions, such as overestimating body size and weight, contribute to the maintenance of AN symptoms (Fairburn et al., 2003).

Social Factors:

AN is not solely determined by biological and psychological factors but is also influenced by various social factors. Sociocultural influences, such as societal beauty ideals emphasizing thinness, contribute to body dissatisfaction and disordered eating behaviors (Thompson et al., 1999). Additionally, interpersonal factors, such as family dynamics, peer relationships, and social pressures, play a significant role in the development and perpetuation of AN (Jacobi et al., 2004). The social context influences body image dissatisfaction, dietary restraint, and weight control behaviors among individuals with AN.

Research Objectives:

The primary objective of this research proposal is to investigate the biopsychosocial factors influencing the development and maintenance of AN. Specifically, the research aims to:

1. Identify the genetic factors associated with AN susceptibility.
2. Examine the neural correlates underlying the cognitive and emotional dysregulation in AN.
3. Investigate the role of body image dissatisfaction, perfectionism, and distorted cognitions in the development and maintenance of AN.
4. Explore the influence of sociocultural factors, including societal beauty ideals and social pressures, on the development of AN.
5. Examine the impact of family dynamics and peer relationships on the development and maintenance of AN.



The study will involve recruiting individuals diagnosed with AN according to the diagnostic criteria outlined in the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5; American Psychiatric Association, 2013). A total sample size of 150 participants will be recruited from various eating disorder treatment centers and clinics from diverse geographical areas.


A cross-sectional design will be employed to investigate the biopsychosocial factors associated with AN. Participants will be assessed on a range of measures related to genetics, neurobiology, psychology, and social factors associated with AN.


Participants will be assessed using a combination of self-report questionnaires, structured interviews, and laboratory-based assessments. They will complete measures assessing AN symptoms, body image dissatisfaction, perfectionism, distorted cognitions, genetic predisposition, and environmental factors. Additionally, participants will undergo neuroimaging scans to investigate neural correlates associated with AN.

Data Analysis:

Data analysis will include descriptive statistics (e.g., means, standard deviations) to summarize participant characteristics and AN symptom severity. Inferential statistics, such as correlations, regression analyses, and structural equation modeling, will be conducted to examine the relationships between biopsychosocial factors and AN. Statistical analyses will be performed using SPSS and AMOS software.

Ethical Considerations:

This research proposal will adhere to the ethical guidelines outlined by the American Psychological Association (APA) and World Medical Association (WMA). Participants’ privacy and confidentiality will be ensured, and informed consent will be obtained prior to their inclusion in the study. Researchers will seek approval from relevant institutional review boards before conducting the study.


Understanding the biopsychosocial factors contributing to AN is critical for developing effective prevention and treatment strategies. This research proposal outlines a comprehensive investigation into the genetic, neurobiological, psychological, and social factors associated with AN. By identifying these factors, interventions can be tailored to address specific areas of vulnerability and enhance the overall effectiveness of treatment approaches.
