Cancer patients as 'experts' in defining quality of life domains. A multicentre survey by the Italian Group for the Evaluation of Outcomes in Oncology (IGEO)

Although the subjective nature of quality of life is generally accepted, less attention has been paid to the procedure of selecting domains to be explored with questionnaires. To explore what contributes to cancer patients' quality of life, a survey was conducted with the aim of identifying contents of quality of life using cancer patients as 'experts'. A questionnaire with open-ended items aimed at exploring the meaning of quality of life and at determining the contents of health and not health related quality of life, was submitted to a sample of cancer patients stratified by residence, cancer site and stage of disease. The 248 questionnaires received were transcribed and broken down into phrases to allow coding. A content analysis was performed, using as a conceptual framework, the domains identified by the Italian Society of Psycho-Oncology. Overall, 43 domains and a list of symptoms were identified. The two most frequently reported symptoms were pain (21.4% patients) and fatigue (14.1% patients). Social relationships and psychological domains were heavily represented. Twenty sub-domains related to the domain `psychological well-being'. This study suggests that information on the content of quality of life questionnaires to be submitted to people affected by a specific disease, should be derived by studying people suffering the specific disease. These results reinforce the criticism that available quality of life instruments are more likely to reflect the perspective of health professionals than patients

Objective and rational evaluation of the quality of life in oncology in the first phase of the QVONC project

Although the subjective nature of quality of life perception is generally accepted, less attention has been paid to the procedure of selecting domains to be explored with questionnaires. In most cases domains are selected by panel of experts. It is not known whether these domains are relevant for the patients. Moreover, questionnaires developed in 'foreign' countries may not be culturally sound or relevant for patients living in different cultural background. In order to explore what really contributes to quality of life of Italian patients, a survey was conducted with the aim of identifying any dimension of quality of life, positively or negatively impacted on from the illness and therapies. A sample of two hundred and eighty-eight cancer patients with previously specified characteristics (primary tumor, stage of disease and place of residence) were identified. After consenting to participate to the study, a staff member (a physician, a nurse or a psychologist) asked the patient to complete an open-ended questionnaire in the out-patient clinic or at home. This questionnaire, partially derived from a study by Padilla et al. was made up of 5 questions: 'What does the term quality of life mean to you?', 'What contributes to a good quality of life?', 'What contributes to a poor or bad quality of life?', 'Which either physical or psychological symptom interferes with your quality of life?', 'State any positive or negative change in your quality of life, due to illness or treatments'. The first question was asked to explore the meaning of quality of life for the patient; the second and third question were asked to determine the contents of quality of life not health related; the fourth question and the diary provided information about quality of life contents related to his own experience of disease. Two hundred and forty-eight questionnaires (86.1%) were obtained from 7 Cancer Centres participating in the study (Genova, Milano, Roma, Perugia, Napoli, Cagliari, Palermo). All the questionnaires were transcribed and subsequently broken down in phrases on a form that allowed coding. Three raters (a research nurse, an oncologist and a clinical psychologist) made the content analysis using as conceptual framework the list of domains identified by the Italian Society of Psycho-Oncology. The present study shows the possibility to define the content domain of quality of life attributes for cancer patients, using patients as experts
