Screening and assessment tools

On this page you will find links to evidence-based self-assessment tools, developed by academics working in perinatal mental health, to help you identify symptoms of perinatal anxiety.

These tools are designed to help you identify your symptoms, but they are not able to provide you with a clinical diagnosis. The results may be useful in informing how best to help and support women in the perinatal period.

If you wish to use these scales in clinical practice or research, please contact the scale authors directly to obtain permission.


The Perinatal Anxiety Screening Scale (PASS) is a questionnaire, consisting of 31 questions designed to screen for potentially problematic anxiety in pregnant and postnatal women.

The Mothers’ Object Relations Scales are short questionnaire tools that are easy to administer. They are primarily for health practitioners following identification of a possible perinatal mental health difficulty (such as perinatal anxiety), to identify cases where a mother has a maladaptive representation of her infant and to decide on appropriate psychotherapy focused on helping the mother to interpret her infant’s behaviour in a more healthy way. The tool can also be used to track response to therapy.
