A better understanding of the genomics of mental illnesses allowed genetic counselling to be provided to individuals with severe mental illness and their families.

The present study was aimed at assessing the efficacy of genetic counselling for severe mental illnesses with high suicide risk.

Assessment was performed before and after genetic counselling session. Measures used were evaluation of traumatic events in childhood, multidimensional scale for perception of social support (SMSSP), positive and negative affect schedule (PANAS-X), Brief Psychiatric Rating Scale (BPRS), Paykel questionnaire and Genetic Counselling Outcome Scale (GCOS). Paykel's questionnaire consists of five questions about suicidal thoughts and attempts, including: life-weariness, death wishes, suicidal ideation, suicidal plans and suicide attempts. Intervention and assessment lasted approximately one and a half hour. Data from 48 patients was analysed.

Mean age of participants was M=38.4, SD=9.7, and the group was batter represented by females (57%). The participants had various diagnoses, 22% had schizophrenia, 36% bipolar disorder and 42% recurrent depressive disorder. Forty percent of participants reported suicidal ideation and 22,5% had a past history of suicide attempt. Genetic counselling had a direct positive influence upon GCOS specific items and reduced the Paykel scores among participants presenting with suicidal ideation.

Genetic counselling offers information about the disorder, the role of genetics and the impact of environmental factors. Preliminary data suggest that providing genetic counselling decreases the suicidal ideation frequency.
