The study of hereditary cancer related syndromes allows reducing the risk of suffering in cancer to patients and close relatives. The objective of this study will be to evaluate the prevelance of psychological morbidity in patients attended at cancer genetic counselling unit, and to determine the socio-demographic and clinical factors that influence it. A descriptive cross-sectional study will be carried out. Patients attented at the cancer genetic counselling unit, who have criteria for conducting a genetic syndrome test related to hererditary cancer, will be consecutively evaluated. To knowing the psychological morbidity it is relevant to providing care for these patients.
Nowadays several familial cancer syndromes that confer a high lifetime risk of cancer can be identified with genetic testing. The psychological impact of genetic testing and the rates of psychological distress in patients undergoing genetic testing vary between 6 to 65% depending on socio-demographic or clinical characteristics. The effect of baseline distress on post-testing assessments tended to decrease or show little change over time, it may be important to target patients with high baseline distress for additional counseling or intervention both pre-testing and over time.The most robust predictor of future distress is baseline distress, additional factors were associated with cancer risk perception considering family history of cancer, patient's affected or unaffected with cancer, etc... It is relevant to developing and providing care for these patients, it has been demonstrated that enhanced genetic counseling with clinical psychologist to facilitate decision-making process, managing family concerns promoting their communication with and involvement of family members, and attending their emotional distress, can be beneficial. Also, cancer genetic counseling may promote patient use of personal resources and enhance patient health literacy about their syndrome.

OBSERVATIONAL
Enrollment
800
At the initial genetic consultation patients are informed about hereditary cancer risk and the genetic testing process. At the second genetic counseling appointment, after patients done tests, all participants were informed about the study purpose, and they signed the informed consent before the psychometric assessment. Those patients who agreed to participate, they were given the questionnaires to fill in. Also, background characteristics were reported including age, marital relationship, level of education, psychiatric antecedents. The time for completion the self-report measures was about 10 minutes. The psychometric assessment was occurred prior to delivering the results of genetic testing.

To determinate the prevalence of psychological distress of patients studied of the different hereditary cancer syndromes attended at Cancer Genetic Counseling Unit
The Hospital Anxiety and Depression Scale (HADS), it is consisting of two subscales with seven items respectively, anxiety (HADS-A) and depression (HADS-D) symptomatology. The questionnaire is used to evaluate psychological distress in non-psychiatric settings. In general medical outpatients the optimal cut-off point for the screening for psychiatric morbidity seems to be 12, for screening depressive symptomatology seems to be 5 score and 8 (range 7-10) for screening anxiety symptomatology. In Spanish population the HADS demonstrated a good internal consistency and optimal psychometric properties.

To determinate cáncer worry of patients studied of the different hereditary cancer syndromes attended at Cancer Genetic Counseling Unit
Cancer Worry Scale. (CWS), consists of the six-item scale measures concerns about developing cancer, and the impact of these concerns on performing daily tasks among patients at risk for hereditary cancer. The questionnaire are rated on a 4-point Likert scale ranging from "never" to "almost always", with a total value ranging from 6 (minimal worry) to 24 (maximum worry). CWS presented good reliability coefficient in Spanish samples at risk for hereditary cancer.

To determinate the prevalence of psychological morbidity of patients studied of the different hereditary cancer syndromes attended at Cancer Genetic Counseling Unit
The General Health Questionnaire (GHQ-28), measures psychological distress, which is consisting of social functioning, somatic symptoms, anxiety/sleep disturbances, and depression. Each item was scored from 0 to 3. Higher scores indicating greater psychological morbidity, with a cutting score of 5/6 to identify psychiatric morbidity. The Spanish version of the GHQ-28 had adequate psychometric properties.

Psychometric analysis of the questionnaires used to assess psychological distress and cancer worry
Impact of Event Scale (IES), is a self-report measure for distress in relation to a stressful life event, which in our study is cancer risk. IES is using 15 items to measures psychological distress on two subscaless, with intrusion (the extent to which patients are overwhelmed by thoughts and feelings about cancer) and avoidance (tendency to avoid thoughts and feelings about cancer). The intrusion subscale has seven items, the avoidance subscale eight items. Each item is scored from 0 to 5. The psychometric properties of IES are good in samples with increased risk for hereditary breast cancer.
