unsure about patient - malingering?

When do you start to suspect a pt is malingering? Pt is 41yr old female. Diagnosis is unsure at the moment. Has a long history of hospitilizations for SI / depression. One suicide attempt 2 years ago. Reported history of psychosis over the last 10 years that she has been known to our service. AVH / delusions / paranoia. Tried on several AAPs but discontinues before they have the chance to work due to "side effects". Tried typicals but again is non compliant. Appears delusional but... unsure about patient - malingering?
