| Abstract: | The potential effect of attrition in longitudinal research are addressed and a procedure for assessing its effects is recommended. We recommended that researcchers assess the effects of subject attrition on their data by assessing: (1) the presence of non-random sampling using multiple logistic regression, (2) mean difference on the study's variables between those who responded and did not respond to the subsequent data collection, (3) the restriction or enhancement of variances and (4) changes in relationships among variables due to attrition. |
