Results
Seven studies spanning the last 15 years, all
in English, fulfilled the inclusion criteria. Most of
the studies were developed in Europe, with four
(57.1%) in Sweden, one (14.3%) in Belgium, one
(14.3%) in Ireland, and one (14.3%) in the United
Kingdom.
With regard to the methodological approach
of the selected articles, all seven (100%) were
cross-sectional studies. The number of participants
ranged from 24 to 107 individuals.
The seven studies relevant to the research
question were organized by the authors in four ca-
tegories according to the guidelines for integrative
reviews. The categories refer to the main subject of
the articles. The studies were divided into “dyspho-
nia and language comprehension”; “dysphonia and
language comprehension in noisy environments”;
“perception of the dysphonic voice”, and “voice
quality and speech rate”. The following items
were considered in the data evaluation stage: stu-
dy location, design, sample (size and age range),
objectives, main results, and categories of analysis,
conducted by the authors.
