Italian validation of the Penn Acoustic Neuroma Quality of Life Scale (PANQOL-It)

Objective: translate and validate the Penn Acoustic Neuroma Quality of Life Scale into Italian language (PANQOL-It). Methods: the instrument was translated and psychometric properties were subsequently assessed by administering the PANQOL-It to 124 outpatients together with the Depression Anxiety Stress Scale (DASS21) and the Understanding and Communicating domain of the World Health Organization Disability Assessment Schedule II (WHODAS II-D1). The internal consistency, test-retest reliability, construct and criterion-related validity were assessed. Results: Cronbach's alpha coefficient was 0.92 for the total score and ranged from 0.44 to 0.90 in the seven domains. Significant test-retest reliability was observed (intraclass-correlation = 0.75; p < 0.01). Moderate correlation was reported between facial dysfunction domain and objective facial involvement (p < 0.01). Moderate to strong correlations were observed between anxiety, general health domains and all subscales of the DASS21, and between WHODAS II-D1 and general health and energy domains (p < 0.01). These latter results indicated good construct and criterion-related validity respectively. Conclusions: PANQOL-It presented more than acceptable psychometric properties and its adoption is justified for both clinical and research purposes.
