Abstract

Introduction:

Quality of life in patients with acute pharyngitis or tonsillitis is significantly lower than in healthy persons, and it should be taken into account when efficacy of new therapeutic options is investigated.

Objective:

The aim of this study was to develop and validate a reliable instrument that can measure quality of life in adult outpatients with sore throat caused by acute pharyngitis or acute tonsillitis.

Method:

The study was of a cross-sectional type, and assessed reliability and validity of newly developed questionnaire for measurement of quality of life in adult outpatients with sore throat (STQoL) caused by acute pharyngitis or acute tonsillitis. It was conducted on a sample of 282 patients, with mean age 39.0 ± 14.8 years, male/female ratio 104/178 (36.9%/63.1%).

Results:

Final version of the STQoL scale with 21 items showed excellent reliability, with Cronbach’s alpha 0.949. It was temporally stable, and both divergent and convergent validity tests had good results. Factorial analysis revealed three domains, Social/psychic aspects, Physical aspects and Environmental aspects of sore throat related quality of life.

Conclusions:

The STQoL scale is reliable and valid specific instrument for measuring sore throat related quality of life, which is an important treatment outcome in patients with acute pharyngitis or tonsillitis.

The WHO quality of life assessment instrument (WHOQOL-Bref): the importance of its items for cross-cultural research.

S. Saxena, D. Carlson, R. Billington (2001)

One of the fundamental issues in the area of assessment of quality of life is to determine what is important to the individuals' quality of life. This is even more crucial when the instrument is for use in diverse cultural settings. This paper reports on the importance ratings on WHOQOL-Bref items obtained as a part of WHOQOL pilot field trial on 4804 respondents from 15 centres from 14 developed and developing countries using 12 languages. All items were rated as moderately or more important, but this was expected because the items were selected by extensive qualitative research for their salience across the centres. Significant differences on mean importance ratings were found between centres, but rank orders of item for their importance showed highly significant correlations between centres. This was especially true for items in the top and the bottom thirds of the item list arranged by overall importance. Most items were rated as more important by women compared to men and by younger compared to older persons. The results are discussed for their relevance in cross-cultural research on quality of life assessment.

Development of a questionnaire to measure health-related quality of life (HRQoL) in patients with atrial fibrillation (AF-QoL)

Xavier Badia, Fernando Arribas, Jose Miguel Ormaetxe … (2007)

Background The Health-Related Quality of Life (HRQoL) assessment in atrial fibrillation (AF) patients has traditionally been carried out in a poorly standardised fashion, or via the use of non disease-specific HRQoL questionnaires. The development of a HRQoL questionnaire with a good measuring performance will allow for a standardised assessment of the impact of this disease on the patient's daily living. Methods A bibliography review was conducted to identify the most relevant domains of daily living in AF patients. Subsequently, a focus group was created with the aid of cardiologists, and 17 patients were interviewed to identify the most-affected HRQoL domains. A qualitative analysis of the interview answers was performed, which was used to develop a pilot questionnaire administered to a 112-patient sample. Based on patient responses, an analysis was carried out following the statistical procedures defined by the Classical Test Theory (CTT) and the Item Response Theory (IRT). Reliablility was assessed via Cronbach's coefficient alpha and item-total score correlations. A factorial analysis was performed to determine the number of domains. For each domain, a Rasch analysis was carried out, in order to reduce and stand hierarchically the questionnaire items. Results By way of the bibliography review and the expert focus group, 10 domains were identified. The patient interviews allowed for the identification of 286 items that later were downsized to 40 items. The resultant preliminary questionnaire was administered to a 112-patient sample (pilot study). The Rasch analysis led to the definition of two domains, comprising 7 and 11 items respectively, which corresponded to the psychological and physical domains (18 items total), thereby giving rise to the initial AF-QoL-18 questionnaire. Cronbach's coefficient alpha was acceptable (0.91). Conclusion An initial HRQoL questionnaire, AFQoL-18, has been developed to assess HRQoL in AF patients.
