The TEAQV (Tableau d'évaluation assistée de qualité de vie) is an instrument designed to standardize the collection of quality of life data among patients with chronic psychiatric or somatic diseases. This instrument is a two-part. 7 point-scale (0 = extremely bad; 6 = excellent), self-rated quantitative evaluation of quality of life at different time points in 4 areas (physical and psychological well-being, family relationships, professional activity). The first part is a one time retrospective lifetime evaluation whereas the second part is a current state evaluation that can be prospectively repeated. Time points are determined by important periods during the illness or treatment course. This instrument is administered by a trained interviewer in 5 to 10 minutes. The TEAQV has been used in different populations. Correlation coefficients between TEAQV current state and conventional scales were studies. Among 26 lung and heart-lung transplant patients, the correlation coefficients between TEAQV and the Sickness Impact Profile are: physical: -.622; psychological: -.406. Among 18, treated, opioid dependent patients, the correlation coefficients between TEAQV and the Addiction Severity Index are: physical: -.548; psychological: -.763; social professional: -.747; family: -.341. Our early results with the TEAQV suggest that it is an easy to use and beneficial instrument to assess quality of life.
