- Aims and objectives To explore coping with the perceived psychosocial consequences of a false-positive screening mammography. Background Mammographic screening has been found effective to decrease breast cancer (BC) mortality, yet there are adverse effects. Psychosocial consequences of false-positive mammographic screening have mainly been investigated from a population-based perspective. A call for qualitative studies to further explore these consequences has thus been postulated. To date, qualitative studies have elucidated women's experiences following their recall breast examinations, but their coping with perceived psychosocial consequences of a false-positive screening mammography has not yet been explored. Design An explorative qualitative study. Methods Face-to-face interviews were held with a purposive heterogeneous sample of 13 Swedish-speaking women with a false-positive screening mammography. The transcripts were analysed by the use of an inductive content analysis. Results Coping with the perceived psychosocial consequences of a false-positive screening mammography implied a roller coaster of emotion and sense. Women described how they imagined the worst and were in a state of uncertainty feeling threatened by a fatal disease. Conversely, they felt protected, surrounded by their families and being professionally taken care of, which together with perceived sisterhood and self-empowerment evoked strength and hope. Being aware of family responsibility became a crucial matter. Experiencing false-positive screening raised thoughts of thankfulness and reappraisal of life, although an ounce of BC anxiety remained. Consequently, gained awareness about BC screening and values in life surfaced. Conclusions Experiencing a false-positive screening mammography triggers agonising experiences evoking a variety of coping strategies. Provision of screening raises the issue of responsibility for an impact on psychosocial well-being among healthy women. Relevance to clinical practice Gained knowledge might provide a basis for interventions to prevent psychosocial consequences of false-positive mammographic screening and provide support for women with a potentially compromised ability to overcome such consequences.

- Rationale: Experiencing a false-positive screening mammography can cause considerable psychosocial distress. The Consequences of Screening – Breast Cancer questionnaire (COS-BC parts 1 and 2), recently developed in Denmark, is the only condition-specific questionnaire for measuring short- and long-term psychosocial consequences of false-positive mammographic screening. Additional studies are needed to further test the COS-BC before use across cultures. Furthermore, studies have suggested that the consequences of false-positive screening results are partly common across cancer screening settings, although this hypothesis remains largely untested.Objectives: This study (i) assesses content validity of a Swedish version of the COS-BC, (ii) tests whether items expressing long-term consequences of false-positive lung cancer screening results are relevant in a breast cancer screening context and (iii) explores the usefulness of taking results from Rasch analyses of the source version as an aid in questionnaire translation and adaptation.Methods: Following dual-panel translation, content validity was assessed through qualitative interviews with representatives of the target population and the content validity index (CVI). Item locations and Rasch model fit of the source questionnaires were considered in the translation and assessment process.Results: The COS-BC items were generally found relevant and provided coverage of the target construct. Content validity was supported also for nine of 10 lung cancer screening items. Scale CVI values were ≥0.81. Previous Rasch data were useful in facilitating translation and assessing item content validity. The resulting Swedish version of the COS-BC parts 1 and 2 consists of 34 and 23 items, respectively.Conclusion: This study illustrates the value of methodological triangulation and use of data from previous Rasch analyses in questionnaire translation and adaptation. We found support for the hypothesis that consequences of false-positive screening are common across cancer screening settings. Psychometric properties of the Swedish COS-BC remain to be established.

- AIM: To evaluate the psychometric properties of a questionnaire addressing psychosocial consequences of false-positive mammographic screening.BACKGROUND: The Consequences of Screening - Breast Cancer and Lung Cancer questionnaires target psychosocial consequences of false-positive cancer screening. The Consequences of Screening - Breast Cancer questionnaire and ten items not considered lung cancer specific from the Lung Cancer questionnaire have been adapted for use in mammographic screening in Sweden, but remain psychometrically untested.DESIGN: Instrument development paper with psychometric cross-sectional and test-retest design.METHODS: Twelve scales of a Swedish questionnaire version were tested by the Rasch model and traditional psychometric methods. Women with false-positive (Group I, n = 640) and negative (Group II, n = 802) screening mammography responded to the study questionnaire and the Nottingham Health Profile during 2009-2011.RESULTS: Iterative analyses resulted in nine scales demonstrating Rasch model fit, but all scales exhibited poor targeting with relatively large floor effects. Corrected item-total correlations exceeded the recommended criterion. Score differences between Groups I and II and correlations with Nottingham Health Profile sections followed an expected pattern. Cronbach's α and test-retest reliability was acceptable for group-level assessments for ten and seven scales, respectively.CONCLUSIONS: Five scales (Sense of dejection, Anxiety, Behavioural, Sleep and Existential values) of the Swedish questionnaire version demonstrated the best psychometric properties. Other scales should be used more cautiously. Although filling an important gap, causes of concern were identified across scales. The questionnaire should therefore be considered for group-level assessments rather than for measurement of individual degrees of psychosocial consequences.

Psychosocial consequences of false-positive mammography among women attending breast cancer screening. Assessment, prediction, and coping.
- 2014

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- One side-effect of breast cancer (BC) screening is a false-positive mammogram among healthy women. That is, finding(s) on a screening mammogram that lead to additional breast examinations but where the woman is eventually considered free from BC. There is evidence of short-term psychosocial consequences of false-positive BC screening. Regarding long-term consequences, research findings are inconsistent. Lack of validated condition-specific questionnaires targeting such consequences has been postulated as a potential reason for the inconsistencies. Therefore, the Consequences of Screening - Breast Cancer (COS-BC) questionnaire was developed in Denmark. However, before the COS-BC can be used for studying psychosocial consequences of false-positive BC screening across countries, it needs to be adapted and psychometrically (validity and reliability) tested therein. Furthermore, studies of prediction of long-term psychosocial consequences of false-positive BC screening and coping with such consequences might identify women at risk as well as interventions to prevent consequences of screening. Thus, the aim of this thesis was to validate measures of and study the psychosocial consequences of false-positive mammography among women in a Swedish breast cancer screening programme, and to explore how women cope with such a situation. Interviews with 26 women experiencing false-positive screening mammography (Paper I) provided support for the content validity of a Swedish version of the COS-BC; questionnaire items were generally found relevant, understandable, and covering the psychosocial consequences of false-positive BC screening. Psychometric tests (Paper II) of the COS-BC among 1442 women with false-positive or negative mammography demonstrated support for five COS-BC scales (Sense of dejection, Anxiety, Behavioural, Sleep, and Existential values) for cross-sectional and longitudinal group assessments. The remaining seven COS-BC scales should be used more cautiously. One year follow-up study (Paper III, framework) of 399 recalled women and 449 controls showed that women experience psychosocial consequences targeted by the COS-BC scales, except for breast self-examination consequences. Early recall for subsequent mammography demonstrated the strongest prediction of long-term consequences. Dissatisfaction with information at recall, worry about BC, lack of social support, and being foreign-born were also identified as potential predictors. Interviews with 13 women (Paper IV) experiencing psychosocial consequences of false-positive screening mammography revealed that coping with the situation implied a roller coaster of emotions and sense. Social support, sisterhood, and being professionally taken care of were identified as important aspects of coping with the perceived psychosocial consequences of false-positive BC screening (Paper IV). In conclusion, findings of this thesis confirm the occurrence of short-term psychosocial consequences and demonstrated long-term consequences of false-positive screening mammography among women. Early recall should be avoided and personalized information and communication could be of value in order to diminish the risk of long-term psychosocial consequences of false-positive BC screening. Further research is needed to investigate adequate communication styles, especially in order to face multicultural populations in the context of BC screening.
