Overview

A study was conducted to assess gender bias in the Cannabis-Associated Problems Questionnaire (CAPQ), a measure of cannabis-related problems. The study found that two items on the CAPQ exhibited gender-based differential item functioning (DIF). Removal of these items did not significantly alter the scale's relation to cannabis use. Gender differences on the CAPQ persisted after removal of the two problematic items, indicating that true gender differences still exist in men and women's experiences of cannabis-related consequences. The study suggests that future work might opt to use the short form of the CAPQ to minimize gender-based DIF.

BACKGROUND: Gender bias in measures of cannabis problems may differentially affect how men and women endorse items. This gender invariance might mask, exaggerate, or otherwise obscure true distinctions in experiences of cannabis consequences.

Gender Bias in Cannabis-Associated Problems Questionnaire

This research investigates potential gender bias in the Cannabis-Associated Problems Questionnaire (CAPQ), a widely used tool for assessing the negative consequences of cannabis use. The researchers conducted a large-scale study to replicate and extend previous findings of gender-based differential item functioning (DIF) in the CAPQ. This study examines whether the CAPQ accurately measures cannabis-related problems across genders, considering potential biases that may distort the results.

Gender Differences in Cannabis-Associated Problems

The study confirmed the presence of gender-based DIF in the CAPQ, identifying two items that exhibited bias. However, removing these items did not significantly alter the scale's overall relationship to cannabis use. Despite the removal of biased items, the researchers observed persistent gender differences in CAPQ scores, suggesting true gender differences in the experiences of cannabis-related consequences. The study highlights the importance of addressing potential gender bias in measures of substance use problems.

Navigating Gender Differences in Cannabis Use

This research sheds light on the complex issue of gender differences in cannabis use and the importance of using accurate and unbiased measurement tools. The study's findings suggest that the CAPQ may require further refinement to ensure equitable and accurate assessment across genders. This research underscores the need for careful consideration of potential biases in psychological assessments, particularly in the context of substance use and mental health.

Dr. Camel's Conclusion

This study investigates gender bias in the Cannabis-Associated Problems Questionnaire (CAPQ). The researchers confirmed the presence of gender-based DIF, but removing these items did not fully eliminate gender differences in scores. This study emphasizes the importance of addressing potential biases in measures of substance use problems to ensure equitable and accurate assessment.
