Construct validity of modified time-interval analysis in measuring stuttering and trained speaking patterns

Event‐ and interval‐based measurement of stuttering: a review

“…() and does not focus on individual stuttering events but on the presence of a stuttering event within a time interval (Alpermann et al . ). Alpermann et al .…”

“…Alpermann et al . (, ) concluded that modified time‐interval analysis is a reliable and valid measurement technique.…”

“…Alpermann et al . () showed that the ease of judging intervals instead of individual events could make this type of measurement more feasible for clinicians.…”

“…A modified approach of time‐interval analysis with three categories (fluent intervals, stuttered intervals and intervals with trained speech pattern), is currently being studied (Alpermann et al . , ). The modified time‐interval analysis was introduced by Natke and Alpermann () to distinguish the use of trained speech patterns (acquired during stuttering therapy) from stuttered and fluent speech by means of time‐interval analysis.…”

“…An alternative measurement system is based on behaviours occurring within a defined time-interval (Cordes et al 1992). This methodological variation (time-interval analysis) was introduced by Schloss et al (1987) and does not focus on individual stuttering events but on the presence of a stuttering event within a time interval (Alpermann et al 2012). Alpermann et al (2012) showed that the ease of judging intervals instead of individual events could make this type of measurement more feasible for clinicians.…”
