ARL Index and Other Validity Correlates of LibQUAL+ Scores

Abstract

The present study was conducted to address five research questions bearing upon the psychometric validity of LibQUAL+TM scores using data provided by 20,416 participants. It was found that LibQUAL+TM subscale and total scores were highly correlated with satisfaction scores in two independent subsamples. As expected, respondents who reported never using the library systematically rated services lower than did other users. Also as expected, LibQUAL+TM mean scores--intended primarily to measure perceived service quality--were little correlated with institutional ARL Index scores.
