Impact of the diagnostic label for a low-risk prostate lesion: protocol for two online factorial randomised experiments.

INTRODUCTION: Many types of prostate cancer present minimal risk to a man's lifespan or well-being, but existing terminology makes it difficult for men to distinguish these from high-risk prostate cancers. This study aims to explore whether using an alternative label for low-risk prostate cancer influences management choice and anxiety levels among Australian men and their partners. METHODS AND ANALYSIS: We will run two separate studies for Australian men and Australian women with a male partner. Both studies are between-subjects factorial (3×2) randomised online hypothetical experiments. Following consent, eligible participants will be randomised 1:1:1 to three labels: 'low-risk prostate cancer, Gleason Group 1', 'low-risk prostate neoplasm' or 'low-risk prostate lesion'. Participants will then undergo a second randomisation step with 1:1 allocation to the provision of detailed information on the benefits and harms of different management choices versus the provision of less detailed information about management choices. The required sample sizes are 1290 men and 1410 women. The primary outcome is the participant choice of their preferred management strategy: no immediate treatment (prostate-specific antigen (PSA)-based monitoring or active surveillance using PSA, MRI, biopsy with delayed treatment for disease progression) versus immediate treatment (prostatectomy or radiation therapy). Secondary outcomes include preferred management choice (from the four options listed above), diagnosis anxiety, management choice anxiety and management choice at a later time point (for participants who initially choose a monitoring strategy). ETHICS AND DISSEMINATION: Ethics approval has been received from The University of Sydney Human Research Ethics Committee (2023/572). The results of the study will be published in a peer-reviewed medical journal and a plain language summary of the findings will be shared on the Wiser Healthcare publications page http://www.wiserhealthcare.org.au/category/publications/ TRIAL REGISTRATION NUMBERS: Australian New Zealand Clinical Trials Registry (ID 386701 and 386889).

ADHD in the college student: is anyone else worried?

The illegal, non-prescriptive use of prescription stimulants appears to be growing among college students. Recent analyses using DSM-IV criteria suggest that this group of misusers may actually represent cases of undiagnosed ADHD. Such analyses, however, are limited by a diagnostic system that is neither contextural nor dimensional. The ADHD symptoms of the newly diagnosed college student may be highly context and time specific and represent a normal response to temporarily increased demands on intellect and motivation. Diagnosing college students who are misusing stimulants with ADHD runs the risk of further trivializing the ADHD diagnosis. Also from a historical perspective, legitimizing the use of prescription stimulants in this age group may unintentionally only further increase the likelihood of a greater prescription stimulant abuse epidemic.
