OBJECTIVES: To conduct a systematic review of the effects of genetic counselling and testing for familial breast cancer on women's perception of risk and psychological morbidity. DATA SOURCES: MEDLINE, PsychLIT and EMBASE were searched for the period 1980-2001. STUDY SELECTION: Studies were eligible if published in a peer-reviewed journal in English, included women with a family history of breast cancer who underwent genetic counselling or testing and had either a randomised controlled trial or prospective design, with a pre- and at least one post-counselling assessment. DATA SYNTHESIS: As there was considerable heterogeneity in populations and measures, results were summarised rather than subjected to meta-analysis. RESULTS: Overall, genetic counselling and testing appear to produce psychological benefits and to improve accuracy of risk perception. Carriers of mutations in cancer predisposition genes did not experience significant increases in depression and anxiety after disclosure of their mutation status, while non-carriers experienced significant relief. Women who were tested but declined to learn their results seemed to be at greater risk of a worse psychological outcome. CONCLUSIONS: To date, the data on psychological outcomes after genetic counselling and testing are reassuring. However, few studies used a randomised trial design, limiting the strength of the conclusions. Follow-up to date has been short, and we know little about the long-term impact of testing on patient behaviours, perceptions and psychological state.
It has been suggested that lack of awareness of illness in schizophrenia may result from deficits in executive function and/or an avoidant style of coping. To examine this question, 132 persons with schizophrenia spectrum disorders were rated as either "aware," "partially unaware" or "unaware" of: (a) their illness, (b) need for treatment and (c) consequences of disorder on the abbreviated Scale to Assess Unawareness of Mental Disorder. We next compared the performance of the aware, partially unaware and unaware groups on the "escape-avoidance" and "positive reappraisal" subtests of the Ways of Coping Questionnaire and on two tests of executive function: the Letter Number Sequencing Subtest of the WAIS III and Wisconsin Card Sorting Test. MANCOVA followed by ANCOVA and planned comparisons, controlling for age indicated that the participants who were unaware of symptoms, treatment need and consequences generally performed more poorly than the aware groups on tests of executive function. Participants unaware of symptoms also had a greater preference for positive reappraisal than aware or partially unaware participants. The participants unaware of the consequences of disorder endorsed a greater preference for escape-avoidance than the partially unaware participants. Implications for understanding the etiology of lack of awareness in schizophrenia are discussed.
