between the BAI an the STAI my limited experience is that the STAI is a better measure; the BAI tends to correlate very strongly with the BDI. the stai also correlates with depression (expectable) but seems to behave well. also offers state and trait subscales which really do behave as state and trait; ie low test retest correlation between atate than trait scores

Dear Mohammad,

Anxiety correlates with depression assessed ot not with any instrument! Personally I like BAI.

BAI  + Maternal or Paternal Antenatal Attachment Scales were used in:

BMC Women's Health 2011, 11:33 

The effect of stress and anxiety associated with maternal prenatal diagnosis on feto-maternal attachment.  Sara J Allison et al.

"200 women were recruited at booking, 14 women and 20 partners after an invasive test and 81 women following an anomaly scan. A questionnaire was completed using the Beck Anxiety Inventory and Maternal or Paternal Antenatal Attachment Scales."

The following questionnaires are useful for screening of anxiety:

• BAI (Beck Anxiety Inventory)
• GAD-7 (Generalized Anxiety Disorder = PHQ Anxiety Scale)
• HADS (Hamilton Anxiety Depression Scale).

Confirming clinical diagnosis you can use the CIDI (Composite International Diagnostic Interview)
