Quality of life and patient satisfaction are two important concepts in health care, especially in chronic diseases. Currently, there are several instruments available to determine this, but many are not easily applicable in daily practice because of their length and the consequential effort they require from both patients and caregivers.
In the UK, Benson et al. recently developed two short generic patient questionnaires on quality of life and patient satisfaction: the howRu and howRwe questionnaires. Both questionnaires contain four items.
The howRU questionnaire has already been validated and seems highly applicable to be used in large patient groups. The howRwe questionnaire has not been validated yet. The reliability of both questionnaires has not been assessed either. The procedure as suggested by Kocks et al. provides us with the opportunity to perform a reliability procedure on patient level.
The purpose of this study is to assess the reliability of the howRU and the howRwe questionnaires on patient level in the Dutch population.
|Condition or disease|
|Quality of Life|
Prior to the start of this study, the howRU and howRwe questionnaires have been translated into Dutch by the MAPI-institute.
All possible eligible patients who are visiting the general practice between February 2013 and April 2013 are asked to complete the howRU questionnaire prior to consultation and the howRwe questionnaire directly after consultation. The scores are not shown to the health care provider who will also complete both questionnaires after consultation as he/she thought the patient should have completed the questionnaires.
An investigator will then select patients based on the scores on the howRU and howRwe questionnaires and their diseases. We will aim to include at least 90 patients: a minimum of 30 patients with diabetes, 30 COPD patients and 30 persons without these diseases. For each patient category, a maximum of 15 patients with a maximum score (defined as 10-12) will be included. All other patients need to have lower scores. As this study aims to assess the reliability of the questionnaires, it is not necessary to select the study participants at random.
The selected patients will be asked to participate in our study. Participating patients will be asked to fill in other questionnaires (EQ-5D and Europep) and the investigator will hold semi-structured interviews, preferably on the day of consultation. Patients are asked to comment on each separate concept of the questionnaires. They are asked what thoughts they had during the completion of the individual questions, and are asked to give examples of these.
The participants' opinions about the questionnaires will also be asked. All interviews will be recorded and fully transcribed. All references to scores on individual items of the questionnaire (in number or words) will be covered with black bars to blind these results. These elaboration will be sent to a reviewing panel consisting of 45 clinicians and 45 patients. They will be instructed to complete the howRU and howRwe questionnaires of a patient, the way they thought the patient should have rated the questionnaires based on the interview, gender and age. Each interview has to be reviewed and scored by five separate clinicians and five patients for both howRU and howRwe.
Each set of interviews, that will be sent out for review, will contain 10 randomly assigned interviews, including information on the patients' gender and age. The order in which interviews will be in the package will be randomised to prevent fatigue of the reviewers and learning effects in the interviews performed later in sequence. Additionally, all interviews will be sent to a panel of patients. These patients will be selected by an investigator.
For statistical analysis SPSS will be used. The data will be manually entered twice to check for errors. The agreement between patient score, treating physician/nurse practitioner and reviewing panel will be presented in Bland & Altman plots for both the howRU and howRwe questionnaires. To assess normality Q-Q plot will be used.
The concordance between patient scores, treating physician/practice nurse scores, and the mean of the scores of the reviewing clinicians and patients will be studied by Lin's concordance correlation (CCC), an extended intraclass correlation (ICC). Additionally, the scores of the five reviewing clinicians will be compared to the scores of the patient panel, also using the ICC.

All participants will fill out the HowRwe and HowRU questionnaires. Although this questionnaire may be considered an intervention, it is not the goal of this study to investigate the questionnaires as an intervention but to investigate whether they are reliable questionnaires.
- Reliability HowRU and HowRwe [ Time Frame: Average 12 weeks ]This primary outcome measure concerns the scores on the howRU and howRwe questionnaires as filled out by the patients and the reviewing panel.
- HowRU and HowRwe physician scores [ Time Frame: 1 day ]The agreement and concordance between patient scores and treating physician/nurse practioner scores on both the howRU and the howRwe questionnaires.
