[Research Presentation] Purpose: áTo compare the use of hypothesis testing in nursing research during the 1980s with the 1990s through analyses of studies in Nursing Research. áIntervening variables included in analyses were number of hypothesis, study purpose, and author education per study. Trends in hypothesis testing were also analyzed including the statement of the purpose, direction, reporting statistical support, and number of authors per study. á Background: Hypothesis testing in science increases the generality of findings and provides the discipline with dependable knowledge. Yet, a trend has been observed of a notable decrease in hypothesis testing in nursing studies.á áMethod: áRetrospective design was used. Five years from the 1980s (1980, 1982, 1983, 1985, 1987) and the 1990s (1990, 1993, 1994, 1995, 1996) were randomly identified to obtain the initial sample (n=582). After eliminating non-research articles, 517 remained for analyses.áResults: Only 29% of the articles published during the two decades stated a hypothesis. During the 1980s, 35% (98/273) stated at least one hypothesis, while during the 1990s, only 21% (52/244) did the same. Logistic analysis showed this decrease was statistically significant by decade (?2=17.44(1), p<.05). Analysis of effects showed that while the first author education had no impact (X2= .95(3), p>.05), the study purpose influenced it significantly (X2= 45(3),á p<.01):á explanatory (X2=10.30(1), p<.05) and prediction/control studies (X2= 17.19(1),á p<.05 ) had significantly positive effect, exploratory studies had no effect (X2=.75(1), p>.05), and descriptive studies had negative effect (X2= 32.52(1), p<.05) with an estimate value of -2.31. áImplications: Nursing research studies showed a trend towards a declining use of hypothesis testing from 1980s to the 1990s. Study purpose had an effect during both decades whether or not a study would include hypothesis. These findings have important implications for doctoral education in nursing. Evaluation of the significance of hypothesis testing for nursing science is recommended.
