Assessing the validity of the Quality of Life Enjoyment and Satisfaction Questionnaire Short Form in adults with ADHD.
OBJECTIVE
The authors assessed the psychometric properties of the Quality of Life Enjoyment and Satisfaction Questionnaire-Short Form (Q-LES-QSF) in adults with ADHD.


METHODS
One hundred fifty ADHD and 134 non-ADHD adults from a case-control study and 173 adults randomized to placebo or methylphenidate were assessed with the Q-LES-QSF and the Social Adjustment Scale (SAS). Response to change was estimated by comparing change in Q-LES-QSF scores in responders and nonresponders in our randomized clinical trial.


RESULTS
Internal consistency of the Q-LES-QSF items was .88, and the correlation between the Q-LES-QSF total score and the SAS total T score was .72 in adults with ADHD. ADHD cases had statistically significantly poorer scores on the Q-LES-QSF than controls (76.5 +/- 10.9 vs. 59.2 +/- 17.3, p < .001), whereas ADHD responders showed Q-LES-QSF improvement compared to nonresponders (76.1 +/- 12.0 versus 67.9 +/- 14.5, p < .001).


CONCLUSIONS
These results support the validity of the Q-LES-QSF as a measure of quality of life in adults with ADHD.
