Suppоse а teаm оf reseаrchers was interested in studying whether individuals with generalized anxiety disоrder are more likely to abuse substances. The researchers used a cross-sectional design and sampled individuals who were being treated at the psychiatry department of Tampa General Hospital. After enrolment, the researchers use the medical records of the participants to determine both anxiety disorder status and substance abuse status. The researchers found that substance abuse was 0.90 times more prevalent among individuals with an anxiety disorder compared to individuals without anxiety disorder. In other words, individuals with anxiety disorder less often abused substances compared to individuals without anxiety disorder. The researchers submitted a manuscript with the findings from above to a peer-reviewed journal. One of the reviewers points out that the estimated prevalence ratio of 0.90 is counterintuitive and that this counterintuitive finding may be explained by selection bias. When will there be selection bias in this study on anxiety disorder and substance abuse? Clarify your answer. Hint: two conditions need to hold for selection bias to occur.
