B. Absence of informed consent
C. Reliance on self-report and recall bias
D. Small sample size

Correct answer: C. Reported adverse effects may be under-recognized and warrant greater clinical attention

Explanation: The authors conclude that these self-reported adverse effects are common and deserve greater recognition, while avoiding causal claims.

Which conclusion is most consistent with the authors’ statements?

A. Antidepressants directly cause suicidality in all users
B. Antidepressants should be immediately withdrawn worldwide
C. Reported adverse effects may be under-recognized and warrant greater clinical attention
D. Adverse effects are rare and clinically insignificant

Correct answer: C. Quantitative observational research

Explanation: The study quantitatively analyzes survey responses without manipulating variables, making it observational quantitative research.

What is the correct classification of this study?

A. Experimental clinical research
B. Qualitative interview study
C. Quantitative observational research
D. Meta-analysis

Correct answer: B. Increase monitoring and informed consent regarding adverse effects

Explanation: The discussion emphasizes the need for better patient information, monitoring, and acknowledgment of adverse effects.

According to the article, what is a key implication for clinicians?
