BACKGROUND Routine screening for emotional health difficulties in women during pregnancy is now advocated in several countries. There is a need therefore to compare the performance of different self-report measures to accomplish this. This study reports on the comparative performance of two such measures- the well-established PHQ-2, which aims to detect depression, and the more recent MGMQ, which aims to detect a wide array of negative emotions. METHOD Women (N = 2292) attending a public hospital antenatal clinic over a 14-month period completed the two measures, either on their own (72%), verbally administered by the midwife (25%), or with an interpreter (3%). RESULTS Similar rates of women screened positive on each instrument (PHQ-2: 11.6%; MGMQ: 12.3%), but the overlap between the two measures was low. The PHQ-2 only detected 58% of the MGMQ screen positive women, while the MGMQ detected 89.5% of the PHQ-2 screen positive women. No clinically meaningful difference in screen positive rates on either measure was evident for the administration method. LIMITATIONS No demographic data were available apart from gestational age, and only about half the women presenting to the clinic during the time period were screened with the measures. CONCLUSION The MGMQ detected a greater proportion of women screening positive on the PHQ-2 than vice-versa. This is part due to the MGMQ's focus on a wider range of negative emotions than just depression. Accumulating evidence for this MGMQ indicates that clinical services can consider using this simple measure if they wish to screen for a broad range of negative emotions during pregnancy and postnatally.
