ADHD - Voice Analysis, Vocal Acoustic Biomarkers in Attention Deficit Hyperactivity Disorder (ADHD)

February 7, 2012 updated by: Michael Colla, Charite University, Berlin, Germany

Phase 1 Study of Vocal Acoustic Biomarkers in Attention Deficit Hyperactivity Disorder (ADHD)

The purpose of this study is to detect specific vocal acoustic patterns in the voice of attention deficit hyperactivity disorder (ADHD) patients.

Study Overview

Status

Unknown

Detailed Description

This project aims to develop an objective diagnostic instrument for ADHD through an automatic voice-analysis system, which uses as input the natural speech of the participants. The underlying voice-analysis procedure was developed by J. Langner at Humboldt University of Berlin (Langner 2003). It ignores the semantic content of spoken words and extracts prosodic and sound features from the speech.

Aims of the study:

  • deliver optimized multivariate logistic regression models of prosodic and sound properties of speech for ADHD.
  • observe sensitivity and specificity of the voice-analysis procedure.

Cohorts and Interventions

Group / Cohort
ADHD - Patients
Adults (18-50 years old). All eligible subjects will experience the voice recording procedure followed by the assessment of adult ADHD diagnostics. The diagnostic guidelines for ADHD in adulthood will be accomplished as outlined by expert consensus of the German Society for Psychiatry, Psychotherapy and Neurology, with a semi-structured clinical interview following the DSM-IV-TR criteria and the ADHD-Checklist (ADHD-CL) for DSM-IV (Hesslinger et al., 2002) to assess the severity of ADHD-Symptoms. Childhood ADHD symptoms will be rated retrospectively amongst others by using the short version (WURS-k) of the Wender Utah Rating Scale (Ward et al., 1993), German version (Retz-Junginger et al., 2002). To strengthen the validity of the ADHD diagnosis the reported symptoms were corroborated by second party reports.
Healthy Controls
Adults(18-50 years old). All eligible subjects will experience the voice recording procedure followed by the ADHD-Checklist (ADHD-CL) for DSM-IV (Hesslinger et al., 2002. To assess the severity of Non-ADHD, the absence of childhood ADHD symptoms will be rated retrospectively amongst others by using the short version (WURS-k) of the Wender Utah Rating Scale (Ward et al., 1993), German version (Retz-Junginger et al., 2002).
