Three mixed methods designs

Mixed methods means integrating the strands, not stapling a survey and some interviews together in the discussion. A convergent design collects both at once and compares them, as the Syria vaccination study did when positive interviews met thin paper records. An explanatory sequential design explains numbers with interviews: clinicians in southern Ethiopia explained why perioperative protocols were rarely used. An exploratory sequential design starts with qualitative work. In Kenya it produced a 9-item perinatal depression screen that outperformed the Edinburgh scale and the PHQ-9.
