A Vignette-Based Measure of Mental Health Literacy (PDR-V): Reliability, Validity, and Mindfulness Associations in a Cross-Sectional Sample.

The PDR-V demonstrated excellent internal consistency as measured by the Kuder-Richardson Formula 20.

• KR-20 reliability coefficient was 0.83, indicating excellent internal consistency
• The PDR-V is a vignette-based assessment of psychological disorder recognition
• Vignettes were based on ICD-11 criteria for major depressive, generalized anxiety, social anxiety, bipolar disorders, PTSD, and schizophrenia
• Sample size was N = 299 participants recruited via TurkPrime

Participants with prior psychotherapy exposure scored significantly higher on the PDR-V.

• Finding was based on independent sample t-tests
• Prior psychotherapy exposure was one of three participant characteristics associated with significantly higher PDR-V scores
• The other significant group differences were history of mental health diagnosis and education level

Participants with a history of mental health diagnosis scored significantly higher on the PDR-V.

• Finding was based on independent sample t-tests
• This was identified alongside prior psychotherapy exposure and education level as a significant predictor of PDR-V performance
• Participants were recruited via TurkPrime and completed multiple validated measures

Unexpectedly, participants reporting lower education levels and no current mindfulness practice scored significantly higher on the PDR-V.

• The authors described these findings as 'unexpected' and as 'anomalies that warrant further investigation'
• Lower education level was associated with higher PDR-V scores, contrary to typical expectations
• No current mindfulness practice was also associated with higher PDR-V scores
• Findings are limited by the cross-sectional nature of the study

Higher scores on a validated mental health literacy scale and specific facets of dispositional mindfulness were positively correlated with PDR-V scores.

• Spearman correlations were used to assess these relationships
• The validated MHL scale used was the MHLS (Mental Health Literacy Scale)
• The specific dispositional mindfulness facets positively correlated with PDR-V scores were 'describe' and 'act with awareness' from the FFMQ (Five Facet Mindfulness Questionnaire)
• These correlations support the preliminary convergent validity of the PDR-V

Bipolar disorder had the highest recognition as a psychological problem broadly, while social anxiety had the highest specific disorder identification accuracy rates.

• The PDR-V distinguished between two types of accuracy: recognition of disorder presence broadly and specific disorder identification
• Bipolar disorder performed best on broad problem recognition
• Social anxiety disorder performed best on specific disorder identification accuracy
• Generalized anxiety disorder had the lowest recognition and identification accuracy of all disorders assessed

Generalized anxiety disorder had the lowest recognition and identification accuracy among all disorders included in the PDR-V.

• Six disorders were included in the PDR-V: major depressive disorder, generalized anxiety disorder, social anxiety disorder, bipolar disorder, PTSD, and schizophrenia
• GAD had the lowest performance on both recognition of disorder presence and specific disorder identification
• This contrasts with social anxiety, which had the highest specific identification accuracy

The study used multiple validated measures alongside the PDR-V to assess convergent validity.

• Measures included the FFMQ for dispositional mindfulness, MHLS for mental health literacy, PHQ-9 for depression, GAD-7 for anxiety, and MHSAS for treatment-seeking attitudes
• N = 299 participants completed all measures
• Participants were recruited via TurkPrime (an online crowdsourcing platform)
• The study was cross-sectional in design
