The use of computers to administer psychological assessments has increased considerably with computerized measures displaying increased reliability, decreased administration time, and decreased social desirability distortion as indicated by increased endorsement of negative characteristics. Recently, investigators have progressed to the use of secure internet web sites to administer computerized assessments. Using the internet to administer tests provides several benefits to researchers such as efficiency, a secure way to record and manage data, and facilitating data gathering across multi-site studies. The present study examined the reliability of a web-based administration of the Short Form Health Survey (SF-36; Ware, Snow, Kosinski, & Gandek, 1993), the Aggression Questionnaire (AQ; Buss & Perry, 1992), and the Barratt Impulsiveness Scale (BIS-11; Patton, Stanford, & Barratt, 1995) in ninety-seven veterans (age range 26 to 76; M=50). Reliability was measured by calculating test-retest correlations for each measure and its subscales for each administration type (web-web, web-paper, and paper-paper). All correlations were significant at the .01 level and ranged from .50 to .89 for the web-paper comparison. Regression analyses were also performed to compare the predictive ability of web-based to paper-pencil administration. Chronbach’s alphas were also calculated for each method of administration. Although the current study indicates relative equivalence for the two methods of assessment, we found that the time to administer the web testing was significantly longer than paper and pencil due to our population’s unfamiliarity with computers.
