This study aimed to adapt and validate a pre-existing weight loss questionnaire specific for Olympic weightlifting (OWL) athletes, given their pre-competition body mass (BM) management practices are unknown. A structured four-phase validity process was employed, focusing on content, face validity, and internal reliability. The Delphi technique was applied utilising experts (n = 7) over three anonymous rounds to achieve consensus. Questions were reviewed to determine whether to keep, modify, or delete, then rate the relevance of each (content validity index (CVI)). Online interviews were conducted with a pilot group of OWL athletes (n = 6) to assess readability and item difficulty. A test-retest process was undertaken with a second pilot group (n = 9) to verify questionnaire reliability using Pearson’s correlation. All items in the first round achieved consensus with an item-CVI of 0.93, scale-CVI average of 0.98, and no items were recommended for deletion. The average difficulty rating was 4.8/5. Internal reliability was high for weight history (r = 0.93) and weight loss methods (r = 0.83), and moderate for influences (r = 0.65). The adapted questionnaire was shown to be a valid tool for content and face validity to assess the BM management practices of OWL athletes..

Background: Mood disorders including anxiety are complex and multifactorial. Lifestyle changes caused by job-related or social stress can impact the severity of anxiety and overall quality of life. Currently, prescription drugs are the first course of treatment to manage anxiety disorders. While lifestyle interventions for anxiety treatment have demonstrated positive outcomes, the impact of personalized nutrition therapies is not as well documented in clinical care. In large part this is because Nutritional Psychiatry is a nascent field with few active clinical practices worldwide.

Case Description: A 32 year-old Asian American female presented with new onset anxiety and sought urgent medication management. Upon obtaining a comprehensive medical and psychiatric history, nutritional therapy and counseling was offered as a first line of care. A personalized nutritional psychiatry plan along with lifestyle intervention was created to include lower alcohol consumption, meal planning and healthy snacking, as well as sleep regulation.

Conclusion: This case report demonstrated the use of targeted nutritional psychiatry interventions in a consumer who did not need a pharmaceutical as the first line of therapy resulting in a marked improvement in the anxiety symptoms. It highlights that a comprehensive integrative and holistic approach may be a beneficial option for individuals with GAD.
