First, it adds to the quantitative measures of attrition by illustrating different efforts to minimize the attrition rate based on the qualitative understanding of the effective communication patterns.
The purpose of this research note is to review the challenges and strategies used in a school-based study of bullying and cyber bullying (n = 916) to minimize the attrition of primary (4th grade), middle (7th grade), and high school (10th grade) students and their parents over the three-year study duration.
The strengths of this study are its prospective design; the sample size; and limited loss-of-follow up, minimizing the risk for attrition bias.
89 In the initial phase of treatment, it is more useful to have patients focus on weekly weight loss (eg, losing from ½ to 1 kg per week) and to detect and promptly address any warning sign of weight loss dissatisfaction, thus minimizing the risk of attrition.
Second, in order to maximize our analytic sample by minimizing the risk of the attrition over time, we focused on a sample aged from 60 to 64 years with 18 years of follow-up data, a relatively "young" and healthy group of older adults.
The factors hindering person's participation in the training program require further study in order to both optimize entry and to minimize the training attrition rate.
The objective is to obtain proper transient responses with smooth control actions minimizing the variations of the controller output, hence preserving actuators from untimely attrition.
Previously, schools preferred to accept candidates applying from their immediate geographical area to minimize the risk of attrition during the program.
According to Straus et al, follow-up rates that exceed 95% minimize the potential for attrition bias to exist whereas follow-up rates lower than 80% pose a threat to external validity [ 2, 3].
