Development and validation of an instrument assessing women’s satisfaction with screening mammography in an organized breast cancer screening program

Abstract

BackgroundThe assessment of the quality of mammography services delivered in organized breast cancer screening programs should include measures centered on women’s perceptions. The objective of this study was to develop and validate an instrument in French designed to evaluate the satisfaction of women having a screening mammography.MethodsAn instrument evaluating women’s satisfaction with mammography services was developed using published research, the perceptions of screened women, the expertise of health professionals and a pilot study. Between November 9 and 21, 2011, the questionnaire was sent to 1500 consecutive women having had a screening mammography in eight radiologic facilities designated by the Québec Breast Cancer Screening Program, in Quebec City, Canada. Construct validity, convergent and discriminant validity, reliability and sensitivity of the instrument were examined.ResultsA total of 819 women (55%) participated in the validation study. The factor analysis retained four satisfaction dimensions: satisfaction with 1) the technician’s skills (four items), 2) the physical environment (four items), 3) the staff’s communication skills (three items) and 4) the information given by the program (3 items). The multitrait-scaling analysis showed good convergent and discriminant validity: scaling success was 100% for all subscales. All subscales had good internal consistency (Cronbach’s alphas ≥ 0.86). The satisfaction scores were able to identify groups of women with lower levels of satisfaction, such as younger women or women with pain during breast compression.ConclusionThis brief satisfaction instrument, developed in French, showed good psychometric properties to evaluate satisfaction in women receiving mammographic services in an organized breast cancer screening program.

Construção e Validação Psicométrica do Câncer-Q: Questionário de Conhecimentos da Doença para Pacientes com Câncer

“…O valor do CCI total do instrumento foi de 0,858, o que corrobora o valor sugerido pela literatura (mínimo de 0,8), demonstrando a estabilidade e a confiabilidade do instrumento, evidenciando que sucessivas aplicações desse instrumento produzirão os mesmos resultados ou similares 6 , como é visto em instrumentos de demais estudos na área da Oncologia, que apresentaram confiabilidade e estabilidade no instrumento por meio do método teste e reteste [14][15][16][17] .…”

“…No que concerne à análise fatorial, Chunget al 15 desenvolveram um instrumento com 50 itens para avaliar a qualidade de vida em pacientes com câncer de próstata, e a análise fatorial confirmou quatro fatores, assim como o estudo de Bairati et al 16 no instrumento sobre o conhecimento da mamografia para a detecção precoce do câncer de mama, e Morales-Sanchez et al 20 , em questionário sobre o conhecimento dos fatores de risco para o câncer de pele. O estudo de Lee et al 12 mostrou cinco fatores no instrumento construído e validado na intenção de trabalhar com pacientes com câncer de mama.…”

“…As pesquisas na área do câncer, que utilizaram a análise fatorial para a distribuição dos itens, revelaram que a quantidade de fatores em seus instrumentos acontece em decorrência do câncer ser uma doença de etiologia multifatorial, podendo ter origem na combinação de vários fatores como genéticos, ambientais e de modos de vida 18 . Portanto, ocorreram semelhanças do presente instrumento com os demais citados na literatura decorrente especificamente das áreas do conhecimento, seja na quantidade de itens 12,20 ou na quantidade de fatores nos quais os itens estão distribuídos 12,15,16,20 .…”

The Experience of Mammography Based on the Memoirs of Examinees

“…However, there have been few reports on the individual's experience that might discourage screening. In a study on the factors affecting a patient's decision to undergo mammography, examinees reportedly took into account a variety of factors, such as costs, means of transportation and the extent of pain [8]- [17]. In the present study, the authors believe that it is necessary to similarly focus on the various factors influencing the mammography examinees' decisions and to understand what occurs during the procedure to influence the examinee's view.…”

Analysis of contributing factors of the breast cancer mortality rate in Hungary between 2002 and 2014

“…Similar barriers and suggestions have been described in other studies [66][67][68][69]. A patient navigator system could utilize prevention nurses to organize an effective screening programme by offering education on breast awareness, screening invitation, and management of biennial mammogram appointments.…”
