Methodological challenges in using screening tools for depression in migraine: A systematic review.

Area of Science:

• Neurology
• Psychiatry
• Clinical Research Methodology

Background:

• Depression frequently co-occurs with migraine.
• Screening questionnaires are commonly used to assess depressive symptoms in migraine patients.
• The correct application and interpretation of these tools in migraine studies require investigation.

Purpose of the Study:

• To evaluate the usage and interpretation of common depression screening tools in migraine research.
• To determine if these tools are applied and interpreted correctly in the context of migraine.

Main Methods:

• Systematic PubMed search for studies using Beck Depression Inventory (BDI), Patient Health Questionnaire-9 (PHQ-9), Hospital Anxiety Depression Scale (HADS), or Hamilton Depression Rating Scale (HAM-D).
• Inclusion of studies on adult migraine patients diagnosed per International Classification of Headache Disorders (ICHD-2 or ICHD-3).

Main Results:

• 78 studies were identified, with 35% using a depression screening tool as diagnostic evidence.
• PHQ-9, BDI, and HADS were used in 53%, 46%, and 47% of relevant studies, respectively.
• Only one study confirmed diagnoses with an interview; data presentation was heterogeneous.

Conclusions:

• Using screening tools as sole evidence for depression in migraine may yield inaccurate prevalence estimates.
• There is a critical need for standardized guidelines and validation of depression screening tools specifically for migraine patients.
