Motivators and barriers of tamoxifen use as risk-reducing medication amongst women at increased breast cancer risk: a systematic literature review.

BACKGROUND: Selective estrogen receptor modulators, such as tamoxifen, reduce breast cancer risk by up to 50% in women at increased risk for breast cancer. Despite tamoxifen's well-established efficacy, many studies show that most women are not taking up tamoxifen. This systematic literature review aimed to identify the motivators and barriers to tamoxifen use 's amongst high-risk women. METHODS: Using MEDLINE, PsycINFO, and Embase plus reviewing reference lists of relevant articles published between 1995 and 2016, 31 studies (published in 35 articles) were identified, which addressed high-risk women's decisions about risk-reducing medication to prevent breast cancer and were peer-reviewed primary clinical studies. RESULTS: A range of factors were identified as motivators of, and barriers to, tamoxifen uptake including: perceived risk, breast-cancer-related anxiety, health professional recommendation, perceived drug effectiveness, concerns about side-effects, knowledge and access to information about side-effects, beliefs about the role of risk-reducing medication, provision of a biomarker, preference for other forms of breast cancer risk reduction, previous treatment experience, concerns about randomization in clinical trial protocols and finally altruism. CONCLUSIONS: Results indicate that the decision for high-risk women regarding tamoxifen use or non-use as a risk-reducing medication is not straightforward. Support of women making this decision is essential and needs to encompass the full range of factors, both informational and psychological.

Tailored chemotherapy based on tumour gene expression analysis: breast cancer patients' misinterpretations and positive attitudes.

The aim of this study was to document how breast cancer patients perceive their prognosis and a tailored treatment based on tumour gene expression analysis, and to identify the features of this approach that may impact its clinical application. In-depth interviews were conducted at three French cancer centres with 37 women (35-69 years of age) with node-positive breast cancer undergoing an adjuvant chemotherapy regimen defined on the basis of the genomic signature predicting the outcome after chemotherapy. Several concerns were identified. First, some misconceptions about these methods were identified due to semantic confusions between the terms 'genomic' and 'genetic', which generated anxiety and uncertainty about the future. Second, the 'not done' and 'not interpretable' signatures were misinterpreted by the women and associated with highly negative connotations. However, the use of tumour genomic analysis to adapt the treatment to each patient received most of the patients' approval because it was perceived as an approach facilitating personalised medicine. In conclusion, improving the quality of provider/patient communications should enable patients to play a more active part in the decision making about their treatment. This will ensure that those who agree to have tumour gene analysis have realistic expectations and sound deductions about the final result disclosure process.

Does cancer survivors' health-related quality of life depend on cancer type? Findings from a large French national sample 2 years after cancer diagnosis.

We investigated whether health-related quality of life (HRQL) depends on cancer type, after adjustment for demographic and medical variables. A French national population-based survey was conducted between November and December 2004 to assess surviving cancer patients' HRQL 2 years after diagnosis. HRQL was measured by the 36-Item Short Form Survey scale. The sample included 3900 persons. All cancer diagnoses were entered in the study. We demonstrated that medical and treatment variables have an impact on patients' physical HRQL but not on mental HRQL. Cancer type impacted on physical HRQL, with those suffering from upper aerodigestive tract /lung cancers and haematological malignancies being affected to a greater degree. Disturbing side effects impacted both HRQL domains. Socio-demographic variables had statistically significant effects but not clinically meaningful ones. Socio-economic variables led to potentially clinically meaningful differences for cancer patients' HRQL and represented a socio-economic gradient in HRQL among cancer survivors. From our results, we may assert that cancer survivors, 2 years after cancer diagnosis, share a similar pattern of psychological morbidity, independent of cancer type. Patients disproportionately affected by cancer, such as those with lower educational levels and income, need to be identified and targeted and interventions which address their unique needs and concerns need to be developed.

Participants' uptake of clinical trial results: a randomised experiment.

BACKGROUND: Participants are showing great interest these days in obtaining the results of clinical trials. The aim of this study was to assess patients' uptake and understanding of the results of the trial in which they have participated and the impact of a letter offering patients the possibility of consulting the trial results on a specific website. METHODS: Breast cancer patients participating in a trial on the efficacy of Trastuzumab were randomly subdivided into an Internet group (who received the letter of invitation) and a control group (who did not receive it). Among 115 HER2-positive women from 21 centres, 107 (93%) answered a self-administered questionnaire. RESULTS: Most of the patients in both groups had access to the Internet (72.0%). The majority (97.2%) stated that receiving information about the trial results would be useful, and the oncologist was the most frequently preferred information provider. The Internet group's declared uptake of the trial results was only slightly higher (47.1% vs 33.9%; P=0.166); however, they understood the results significantly more accurately (18.8% vs 5.6%; P=0.039). INTERPRETATION: Although Internet was not the respondents' preferred source of information, the possibility of using this source slightly increased the uptake and understanding of the results.

Subjective interpretation of inconclusive BRCA1/2 cancer genetic test results and transmission of information to the relatives.

OBJECTIVE: BRCA1/2 gene mutations are not frequently identified in breast or ovarian cancer patients who are the first members of their family to be tested. Little is known about how probands interpret and cope with these results, which are generally referred to as 'inconclusive'. The aim of this study was to describe subjective understanding by women with cancer in response to an inconclusive BRCA1/2 test, describing the difficulties or non-difficulties they encountered about the transmission of information to their family. METHODS: A cohort of 30 women with breast/ovarian cancer were followed for a period of up to 2 years after delivery of their inconclusive genetic test results. Self-administered questionnaires with closed and open questions were distributed. A qualitative analysis of open-ended questions is presented here. RESULTS: These women's reactions to inconclusive results were of three kinds. The majority (n=14) were still uncertain about their carrier status, which is an adequate medical interpretation of the results, while others (n=9) took their inconclusive results to mean that they were definitely not carriers, and the women in the last group (n=7) were convinced that they were actually carriers. There was some overlap between these perceptions and actual genetic risk. CONCLUSIONS: The transmission of information to the family was found to differ qualitatively across the three groups and more difficulties in this respect were expressed by those who were uncertain about their carrier status.

Physicians' attitudes towards mammography and prophylactic surgery for hereditary breast/ovarian cancer risk and subsequently published guidelines.

After a BRCA mutation has been identified in the context of hereditary breast/ovarian cancer (HBOC), mammographic screening and prophylactic surgery are two of the main options available to those responsible for the clinical management of healthy women. The aim of this study was to describe the attitudes of specialists towards the clinical management of women with an HBOC risk: this information was collected prior to the publication of the recent French guidelines. A random national sample of 1169 French surgeons, gynaecologists and obstetricians was surveyed using a mailed questionnaire, to which 700 of these physicians (60%) responded. When dealing with a BRCA mutated woman, 88.6% of the respondents said they would recommend mammographic screening, but only 27.1% would recommend that it should be carried out annually from the age of 30 years onwards, as recommended in the French guidelines; 10.9% would find it acceptable to propose prophylactic mastectomy from the age of 30 years, and 22.9% would find it acceptable to propose prophylactic oophorectomy from the age of 35 years. The specialists who agreed with recommending breast/ovarian cancer genetic testing also had more positive attitudes towards prophylactic mastectomy (adj OR = 3.4, 95% CI = 1.4-8.2), as did those who had previously recommended prophylactic mastectomy when gene testing was not yet available (adj OR = 2.06, 95% CI = 1.23-3.44). The respondents' attitudes towards prophylactic oophorectomy and mastectomy were significantly associated (adj OR = 3.9; 95% CI = 2.3-6.5). Previous recommendation of prophylactic mastectomy was associated (P < 0.01) with a higher level of knowledge of breast/ovarian cancer genetics and with medical practice in this field. French physicians' attitudes towards mammographic screening and prophylactic surgery were not in complete agreement with the subsequently published French guidelines, the impact of which has now to be considered. Constantly evolving knowledge about the efficacy of preventive intervention will give practitioners new elements to integrate into their counselling.

Cancer genetic clinics: why do women who already have cancer attend?

Cancer patients attend oncogenetic clinics so that the existence of a genetic risk can be checked and the relatives informed. The aim of this study was to describe the expectations of cancer patients about genetic counselling and their beliefs about the aetiology of their disease. A survey based on self-administered questionnaires before and after the consultation was carried out on 115 women with breast/ovarian cancer who attended one of the six French participating clinics. In 59 cases (51%), the consultees' expectations focused on the preventive options available and in 86 cases (75%) on their offspring; 87 (76%) found the consultation informative. On average, the women rated heredity and diet as lower risk factors (P < 0.05) after the consultation than before. Heredity, stress and the environment were thought to be more decisive than diet, smoking and alcohol. 34 patients who seemed unlikely to have a genetic risk in the consultant's opinion thought heredity to be less relevant (P < 0.05) after the consultation than before. At the time of the survey, cancer patients accounted for at least half of the consultees attending oncogenetic clinics in France. They need to have the clinical specificities of their disease and its medical management explained. They attend mainly for their offspring's sake, whereas healthy clients attend for their own sake.

Cancer genetics clinics: target population and consultees' expectations.

The aim of this study was to determine in healthy consultees attending cancer genetics clinics their risk status, their pathways leading to the clinics, their expectations and perception of cancer risk. In 1994, the consultees at six French centres completed a questionnaire before their first oncogenetic consultation. The oncogeneticists subsequently filled in a standardised form giving their risk assessment. Among the 206 healthy consultees, 91.3% were women, 92.2% had at least one cancer-affected first-degree relative and 73% had a "cancer family risk" as assessed by the oncogeneticist. Sixty-nine per cent of the consultees were referred to the clinics by a physician, 10.4% by their family and 18.8% on their own initiative: 83.5% of the sample perceived their family risk of cancer as being high and this belief was confirmed in 74.3% of the cases studied by the oncogeneticist. The families of self-referred consultees were less often at risk than those of consultees referred by a physician or by their family (P = 0.012). The majority (78%) expected to be informed about cancer prevention and screening, and this expectation depended on the consultee's level of education (P = 0.001). This study shows that medical pathways are more effective than the media as a means of reaching the members of the general population who are genuinely at risk, and shows that fuller information about prevention needs to be provided at cancer genetic consultations.

Disclosure to the family of breast/ovarian cancer genetic test results: patient's willingness and associated factors.

Informed probands are key actors for disclosing genetic information to their relatives when a mutation has been identified in the family. The objectives were to study women's attitudes towards the family disclosure of positive breast cancer genetic testing results and to determine the predictive factors of the diffusion patterns observed. A national multi-center cross-sectional survey was carried out at five French cancer genetic clinics during a 1-year period. Self-administered questionnaires were completed after the consultation by 84.5% (398/471) of women attending breast cancer genetic clinics for the first time. Among the 383 respondents who had at least one living first-degree relative to inform, 8.6% would inform none, 33.2% would inform at least one of them, and 58.2% would inform all of them. The sibship would be the most frequently informed blood relatives, sisters in 86.9% and brothers in 79% compared with mother in 71.4%, children in 70.4%, and father in 64.9%. Women of the family would be more frequently informed than men (P < 0.05). After multivariate adjustment, age, the fact to be affected by cancer, the number of daughters, and the emotional disturbance due to cancer in a close relationship were the main determinants (P < 0.05) of the diffusion patterns observed. The first step of the relatives' attendance to genetic counseling and the proband's willingness to disclose breast cancer genetic tests results was high in this study and was clearly dependent on the women's personal and emotional characteristics.

Tamoxifen and breast cancer risk in women harboring a BRCA1 germline mutation: computed efficacy, effectiveness and impact.

The management of breast cancer prone women remains a tough issue despite the release of institutional guidelines. Currently, only the anti-estrogen agent Tamoxifen and prophylactic surgery are claimed to decrease breast cancer incidence. However, efficacy of Tamoxifen, particularly in BRCA1 gene carriers, remains controversial and acceptability of prophylactic surgery is low. To evaluate the expected impact of Tamoxifen in preventing hereditary breast cancers, a modelling was made according to the efficacy of the treatment with respect to biological predictors of response: estrogen receptor (ER) and pS2 status of a series of 33 BRCA1-related breast cancers (BRCA1-BCs), and using data on BRCA1-BCs penetrance, as well as compliance and acceptability of the strategy. Although, 88% of BRCA1-BCs are ER negative in our series, 30% of cases are pS2 positive, implying a potential hormonal sensitivity of a proportion of these cancers. From our modelling, the expected impact of Tamoxifen in BRCA1 gene carriers is a reduction of breast cancer incidence of about 10% according to acceptability and compliance, close to that of 5% and of 13.5% for prophylactic mastectomy, according to acceptability rates from US and French surveys respectively. Since autonomy of choice is the root of western ethics, cancer prone women should be informed about the low but valuable expected reduction of incidence of breast cancer using Tamoxifen preventive therapy.

Comparison of physicians' and cancer prone women's attitudes about breast/ovarian prophylactic surgery. Results from two national surveys.

Prophylactic surgery is a major issue for breast/ovarian cancer prone women. Bio-clinical data to help in the decision-making are not sufficient. In this context of uncertainty, physicians' and women's attitudes to prophylactic surgery is information of great value. The physicians' attitudes were assessed by a randomised national sample of practitioners involved in breast and ovarian cancer management. The patients' attitudes were appraised with a pre-consultation self- administered questionnaire presented during a one-year period to all women in five cancer genetic clinics chosen, for their representative geographical locations and their activity level. Consent to prophylactic surgery is higher among physicians than among patients (p < 0.0001). Acceptability of mastectomy is lower than that of oophorectomy in both patients and physicians (p < 0.0001 in both groups). In addition, age at which the intervention is proposed to be performed is a key determinant for both mastectomy and oophorectomy acceptability, in both physicians and patients (p < 0.001 for each comparison). Particularly, the age of 40 years seems to be a critical threshold for the acceptability of prophylactic oophorectomy. In contrast, respondents' age at the time of the survey has no significant effect on the acceptability rate. The higher acceptability rate of prophylactic oophorectomy compared to that of mastectomy observed in the physicians' survey is paradoxical because a more substantial medical impact on life expectancy was expected from the latter. Our results indicate that assumed reduced mortality is not the main criterion steering acceptability. It was anticipated that prophylactic mastectomy should be rarely performed in France.

Cancer prone persons. A randomized screening trial based on colonoscopy: background, design and recruitment.

OBJECTIVE: Evidence-based counseling and prevention are not available so far for hereditary cancer prone persons, since we lack data based on clinical trials. There are very few high-risk persons in the population as a whole. Based on a familial history analysis, only 1.2% of all healthy volunteers attending screening centers reached the arbitrary high-risk level defined as a Relative Risk of more than 4. We describe a randomized trial based on colonoscopic screening for colorectal cancer on a sub-group of high-risk group persons. MATERIALS AND METHODS: Among the 77 members of the French Institutional Preventive Center Network, 37 took part in this protocol. During the first 3 years, 850,000 persons were interviewed at these 37 Health centers. The enrollment process was particularly time-consuming, since a large amount of information had to be delivered to the participants. RESULTS: The mean rate of recruitment of eligible candidates was far lower than predicted, averaging only 1.4 per 1,000 persons interviewed instead of the 9/1,000 expected. This mean figure was based, however, on inclusion rates ranging from 0.06/1,000 to 7/1,000 among the different centers. The low rates of recruitment were mainly due to the inter-center heterogeneity (differences in commitment and in the resources), and to the fact that the acceptability of undergoing a colonoscopy turned out to be lower than predicted. CONCLUSION: Population trials on cancer prone persons are feasible, but vast numbers have to be pre- screened to identify the few people with a high hereditary risk and willing to accept screening within a controlled trial.

Impact of prenatal diagnosis by ultrasound on the prevalence of congenital anomalies at birth in southern France.

STUDY OBJECTIVE: The aims were (1) to assess whether termination of pregnancy after prenatal screening by ultrasound affected the prevalence of congenital anomalies at birth, and (2) to examine the trend of this pattern over time. DESIGN: This study deals with congenital anomalies, possibly detectable prenatally or at birth, which were classified as isolated and multiple anomalies; chromosomal anomalies were not included. The prevalence rates of congenital anomalies at birth were determined from case registration data in the Marseille district, France, from the registry of congenital malformations (Eurocat no 22), which covers 23,500 births a year. The chi 2 test for homogeneity in proportions was used to test whether the differences in the total prevalence rates were significant over time. SETTING: The population was defined as all children born to parents living in the Marseille district between January 1 1984 and December 31 1990. PATIENTS: Among the 164,509 pregnancy outcomes monitored during the study, 1795 children with a single congenital anomaly and 288 with multiple congenital anomalies detectable at birth were assessed. MEASUREMENTS AND MAIN RESULTS: The percentage of pregnancy terminations was higher in the case of multiple anomalies (16%) than with single ones (7.5%). Leaving aside the lethal birth defects, this percentage became 7.9% in the case of multiple anomalies and 4.3% with isolated ones. A significant increase (p < 0.001) occurred over the seven year study period in the total percentage of terminations because of isolated anomalies but not in that involving multiple ones. The increase observed in the former case was found to be mainly attributable to an increase in the number of terminations of pregnancy undertaken because of anomalies which were either lethal or associated with very low survival rates (p < 0.001). CONCLUSIONS: Termination of pregnancy after prenatal ultrasound examination was found to have a definite impact on the prevalence at birth of lethal and congenital anomalies with a low survival rate, and this impact tended to increase over time. No such impact was observed in the case of congenital anomalies associated with high survival rates.

Time elapsing from cancer diagnosis and anxiety in women attending cancer genetic clinics.

The aim of this study was to investigate the effects of cancer genetic consultations on feelings of anxiety in women with breast/ovarian cancer. Among the 138 women attending six French clinics during a one-year period, 115 (83.3%) answered pre- and post-consultation questionnaires. The state anxiety score (Spielberger's STAI) was lower (paired t-test, p<0.001) after the consultation (34.7 9.4) than before (38.8 10.5). The time elapsing since cancer diagnosis (r=-0.28, p=0.007) was the main predictor of the decrease in anxiety. The patients consulting earlier after their cancer was diagnosed were more anxious before the consultation than those consulting later: whereas their anxiety states after the consultation were similar. The consultation effectively decreased the anxiety observed and the anxiety felt by cancer patients before the consultation may constitute an anticipatory stress response that should be investigated.

Patients' and surgeons' perspectives on axillary surgery for breast cancer.

AIMS: The objectives of this study were to compare the postoperative morbidity of Sentinel lymph node biopsy (SLNB) and axillary lymph node dissection (ALND) and to compare the views of surgeons and patients regarding postoperative morbidity. METHODS: A prospective and comparative study was initiated to evaluate, 1 year after surgery, morbidity and sequelae after SLNB in 231 patients. Group I (n=141) underwent SLNB without ALND, group II (n=90) underwent SLNB followed by ALND when SLN where involved. Morbidity analysis was performed, respectively, by surgeons and patients. RESULTS: One hundred and eighty-five patients (80.5%) completed the questionnaire including 113 with SLNB alone, and 72 with ALND. One year after surgery, SLNB produced less morbidity than ALND for symptoms and function. There were significantly different assessments between surgeons and patients for pain, arm mobility and sensitiveness. CONCLUSIONS: One-year postoperative morbidity after SLNB is significantly lower than after ALND but views of surgeons and patients appears to be significantly different. Additional data are required to assess late consequences of axillary surgery.

Prevention and genetic testing for breast cancer: variations in medical decisions.

The discovery linking the genes BRCA1&2 to familial breast cancer played an important role in the clinical practice of geneticists and physicians. The availability of genetic tests for BRCA gene mutations prompted cancer geneticists to give information about genetic risk and to assess many women with a personal or family history of breast or ovarian cancer to inform them of preventive measures. These consist mainly of breast self-examination, mammography screening, chemoprevention and prophylactic surgery (mastectomy, oophorectomy). This paper examines clinical practices related to hereditary breast cancer testing and introduces a number of results from a survey carried out, between 1996 and 1998, in three clinics located in Montreal (Quebec, Canada), Marseilles (France) and Manchester (Great Britain). Results show substantial differences in the way cancer geneticists deal with environmental risk factors, breast and ovarian cancer testing, and chemoprevention and prophylactic surgery. Differences across cities persist in the multivariate analysis, suggesting that attitudes towards preventive measures may be partially explained by cultural factors. Different dimensions of culture are discussed including the social representation of health and risk, the interpretation of scientific evidence and the role of innovation leadership.

[Knowledge and management of psychological side effects of chemotherapies]. / Connaître et prendre en charge les effets secondaires psychologiques des chimiothérapies anticancéreuses.

This review on psychological consequences of chemotherapies presents the research directions developed during the last two years: the first direction is a descriptive one and identifies the prevalence of psychological syndromes associated with these treatments. Besides psychological distress such as anxiety and depression, often underestimated in medical practice, some secondary cognitive deficiencies ought to be considered. It is also emphasized that the point of view of patients should be taken into account since their own assessment of the side effects is often discrepant with those of their medical providers. The second orientation developed here is the evaluation of actions aimed at controlling and alleviating the psychological consequences of these treatments by different protocols of information and psychotherapy. Good quality research is necessary in psycho-oncology in France and should be co-ordinated with clinical practice in psychology the offer of which is still too limited in our present health care system.

[Attitudes towards screening and prevention of breast and ovarian cancers with hereditary predisposition. Survey by female gynecologists in the north of France]. / Attitudes envers le dépistage et la prévention des cancers mammaires et ovariens avec prédisposition héréditaire. Enquête auprès des femmes gynécologues de la région Nord de la France.

Search for mutations of BRCA1 in women at hereditary risk for cancer is now possible. We asked the female gynaecologists of our county (north of France) their opinion about the search of a mutation of BRCA1 if they had a familial risk of breast cancer. Our aim was to obtain the opinion of informed women about their willingness to do the test for themselves and about the consequences they should accept. One hundred and eighty-three women received a questionnaire by post. The response rate was 56.3%. Twenty-four percent of the responders had a first degree relative with breast cancer. Most of the responders (87.4%; IC 95%: 81-93.8) would ask for the search of a mutation of BRCA1. The percentage of women who would accept the test is smaller for the women who have a first degree relative with breast cancer (72.0% vs 92.3%; P = 0.02). The reasons given to do the test were a better screening or prevention (69.7%) and the knowledge of a personal risk (49.4%). For breast cancer, 93.2% (95% CI: 88.4-98) would accept a screening protocol, 30.1% (CI: 21.3-38.9) would accept a prophylactic bilateral mastectomy. For ovarian cancer, 93.2% (CI: 88.4-98) would accept the screening, 52.4% (CI: 42.8-62) would accept a prophylactic ovariectomy. In conclusion, most of the informed women would ask for the test and the surgical options for reducing the risk of cancer are not absolutely rejected. Of course, only future studies will state precisely the choice of truly implicated women.

[Screening practices and familial antecedents of colorectal cancer. Survey with a voluntary population]. / Pratiques de dépistage et antécédents familiaux de cancer colorectal. Une enquête en population volontaire.

OBJECTIVES: To analyze the association between colorectal cancer positive family history and screening practices. METHODS: The study concerned 6733 individuals attending a center for periodic health examination. RESULTS: Five hundred fifty four patients (8.2%) declared a positive family history of colorectal cancer; 269 (4%) were first degree relatives of the affected member and among them, 73 (1.1%) have pointed out the occurrence of at least one cancer case below age 50. Out of 554 subjects with a family history (regardless the degree of kinship), 132 (23.8%) have had an endoscopic examination versus 8.9% of subjects without positive family history. The rate of endoscopy increased with the number of cases in a family (P < 0.0001). CONCLUSION: Family members undertake more endoscopic examinations when a family history of colorectal is reported. A correlation with the number of affected relatives has been found.

[Measurement of anxiety state in women: a short-form scale]. / Mesure en population féminine de l'état d'anxiété: une forme courte d'échelle.

BACKGROUND: Clinical epidemiology and psychosocial studies often take into account the measurement of anxiety. Our objective was to develop and validate a short form scale of anxiety state from the Spielberger's State Trait Anxiety Inventory (STAI-Y), one of the most widely used scales. METHODS: This study was carried out on French samples of women with different levels of anxiety. The first step was to select from the original 20-items scale, the items susceptible to compose two short forms scales: an 8-items (18-STAI) and a 5-items (15-STAI) one. It was carried out on patients attending cancer genetic clinics (n1 = 160, n2 = 41). The second step was carried out on 3 other samples of women (n3 = 150, n4 = 167, n5 = 105) and measured the psychometric characteristics of the short-form scales obtained previously. RESULTS: The correlation coefficients between the short-forms and the complete 20-items form were very high (> 0.90) in particular for the 18-STAI (r > 0.95). Both short forms are sensitive to change. The internal consistency measured by Cronbach-alpha was comparable to the original scale. The results obtained with the 18 scale and another 10 items Spielberger's short-form scale are comparable and better than those with the 15 scale. CONCLUSION: The 18 French short-form scale, balanced with positive and negative items, can be recommended for the measurement of state anxiety when the complete form cannot be used.
