The time from a patients' first awareness of symptoms to the first presentation to a healthcare professional often constitutes the greatest proportion of the time to diagnosis of cancer. This research aimed to develop and validate a theory-based questionnaire (the 'Pathways To Healthcare Questionnaire'; PaTH-Q), to determine the factors that contribute to patients' decision to seek help. Study One: A systematic review to determine how studies have measured psychosocial factors affecting time to presentation for [potential] cancer symptoms. Results indicated that the majority of studies (n = 36) were atheoretical and failed to use valid and reliable tools to measure psychosocial factors which may influence help-seeking behaviour. Study Two: A secondary qualitative analysis of the factors that contribute to patients' appraisal of symptoms and decision to seek help. The study examined whether responses given by (n = 49) interviewees, who had sought help for [potential] symptoms of cancer, can be classified according to contributing factors within the appraisal interval of the Model of Pathways to Treatment (Scott et al., 2013). Study Three: Generation of items for the PaTH-Q was informed by the findings of Study One and Study Two. Content validity of the questionnaire was supported by subscale and item content validity index. Cognitive interviewing indicated that the PaTH-Q was interpreted as intended. Study Four: Initial psychometric testing of the PaTH-Q via a retrospective cross-sectional study with individuals (n = 50) previously diagnosed with cancer. Although further work is required to adequately establish the psychometric properties of the PaTH-Q, the study highlighted that the PaTH-Q shows at least acceptable validity and reliability for some of the subscales. Overall, the findings indicate the need for valid and reliable measures, informed by theoretical models, to systematically determine the factors that contribute to symptom appraisal and the decision to seek help.
