Insights
The Haitian-Creole PHQ-9 is a valid tool for measuring depression in men who have sex with men (MSM) in Haiti. HIV-positive MSM reported higher depression rates, highlighting a need for targeted mental health support.
Area of Science:
- Mental Health Research
- Psychometrics
- Global Health
Background:
- Limited data exists on depression among Haitian populations due to a lack of culturally adapted assessment tools.
- Depression screening in vulnerable groups requires validated, linguistically appropriate instruments.
Purpose of the Study:
- To psychometrically evaluate the Haitian-Creole version of the Patient Health Questionnaire-9 (PHQ-9) in men who have sex with men (MSM) in Haiti.
- To assess the reliability and validity of the translated PHQ-9 for depression screening in this population.
Main Methods:
- Cross-sectional study utilizing data from the Integrated Behavioral and Biological HIV Survey (IBBS) for MSM in Haiti.
- A Haitian-Creole version of the PHQ-9 was verbally administered to 1,028 MSM.
- Psychometric analyses included unidimensionality, reliability, construct validity, and differential item functioning (DIF).
Main Results:
- The Haitian-Creole PHQ-9 demonstrated unidimensionality and good internal consistency (α=0.78).
- Evidence of construct validity was found, with HIV-positive MSM reporting significantly higher depression scores (p=0.002).
- No DIF was observed across age, education, sexual orientation, or HIV status.
Conclusions:
- The Haitian-Creole PHQ-9 is a psychometrically sound tool for assessing depression among MSM in Haiti.
- Findings support the use of this tool for identifying depression in this population.
- Further research should explore the predictive validity of depression on health behaviors and outcomes in Haitian MSM.
Background:
There is limited information on depression in Haitians and this is partly attributable to the absence of culturally and linguistically adapted measures for depression.
Objective:
To perform a psychometric evaluation of the Haitian-Creole version of the PHQ-9 administered to men who have sex with men (MSM) in the Republic of Haiti.
Design:
This study uses a cross-sectional design and data are from the Integrated Behavioral and Biological HIV Survey (IBBS) for MSM in Haiti.
Participants:
Inclusion criteria required that participants be male, ≥ 18 years, report sexual relations with a male partner in the last 12 months, and lived in Haiti during the past 3 months. Respondent Driven Sampling was used for participant recruitment.
Main Measures:
A structured questionnaire was verbally administered in Haitian-Creole capturing information on sociodemographics, sexual behaviors, human immunodeficiency virus (HIV) status and depressive symptomatology using the PHQ-9. Psychometric analyses of the translated PHQ-9 assessed unidimensionality, factor structure, reliability, construct validity, and differential item functioning (DIF) across subgroups (age, educational level, sexual orientation and HIV status).
Key Results:
In a study population of 1,028 MSM, the Haitian-Creole version of the PHQ-9 is unidimensional, has moderately high internal consistency reliability (α = 0.78), and shows evidence of construct validity where HIV-positive subjects have greater depression (p = 0.002). There is no evidence of DIF across age, education, sexual orientation or HIV status. HIV-positive MSM are twice as likely to screen positive for moderately severe and severe depressive symptoms compared to their HIV-negative counterparts.
Conclusions:
There is strong evidence for the psychometric adequacy of the translated PHQ-9 screening tool as a measure of depression with MSM in Haiti. Future research is necessary to examine the predictive validity of depression for subsequent health behaviors or clinical outcomes among Haitian MSM.
