A Report on the Information Sub-test of the Naylor-Harwood Adult Intelligence Scale

The purpose of this study is to report data on Information sub-test of the Naylor-Harwood Adult intelligence Scale. Adults (N=55) undergoing a vocational assessment had scores on the Information test that ranged from a low of 4 to a maximum of 24 with a mean score of 14.5 (SD=4.9, 95% CI [13.2,15.8]). The internal consistency reliability (Cronbach alpha) of the Information sub-test is.846. Socio-demographic factors (sex, age, schooling, education, language background) had a small to moderate effect size on information. There were statistically significant relationships between information and (a) reading achievement, (b) a rapid assessment of intelligence and (c) with higher information processing speed. Performance was (d) unrelated to scores on a memory malingering task. The raw scores have been converted to scale scores from 1-20 with a mean of 10 and a standard deviation of 3. An hypothesised model of some influences on general information is introduced.
