BACKGROUND Chemoprevention crossover trials of tea can be more efficient than parallel designs but the attrition and compliance rates with such trials are unknown. METHODS Attrition (dropouts) and compliance with treatment were assessed in a 25-week randomized, placebo controlled, crossover, feasibility clinical trial of four tea treatments to investigate the effect of tea on oral cancer biom...

Dropout is a simple yet effective algorithm for regularizing neural networks by randomly dropping out units through Bernoulli multiplicative noise, and for some restricted problem classes, such as linear or logistic regression, several theoretical studies have demonstrated the equivalence between dropout and a fully deterministic optimization problem with data-dependent Tikhonov regularization....

Between 20-51% of eating disorder clients in inpatient settings and 29-73% in outpatient settings prematurely discontinue treatment. Research has attempted to address this problem by identifying the client characteristics upon entering treatment that predict dropout, but this approach has failed to identify consistent predictors of treatment dropout. Processes that occur early in treatment, suc...

Previous reviews of premature termination have yet to examine whether disparate psychotherapy treatments differ in their dropout rates for specific disorders. Using data from 587 studies, a series of meta-analyses were conducted comparing dropout rates between treatment approaches for 12 separate disorder categories. Although, significant differences between treatment approaches were found for ...

College dropout is widely considered a social problem. In fact, reducing dropout would not necessarily make society better off. This conclusion derives from analysis of the process of college enrollment and completion. The key observation is that students contemplating college entrance do not know whether completion will be feasible or desirable. Hence, enrollment is a decision to initiate an e...

A reasonable estimation of expected dropout rates is vital for adequate sample size calculations in randomized controlled trials (RCTs). Underestimating expected dropouts rates increases the risk of false negative results while overestimating rates results in overly large sample sizes, raising both ethical and economic issues. To estimate expected dropout rates in RCTs on yoga interventions, ME...

BACKGROUND Medical school attrition is important--securing a place in medical school is difficult and a high attrition rate can affect the academic reputation of a medical school and staff morale. More important, however, are the personal consequences of dropout for the student. The aims of our study were to examine factors associated with attrition over a ten-year period (2001-2011) and to stu...

BACKGROUND Rates of treatment dropout in outpatient Dialectical Behavior Therapy (DBT) in the community can be as high as 24 % to 58 %, making dropout a great concern. The primary purpose of this article was to examine predictors of dropout from DBT in a community mental health setting. METHODS Participants were 56 consumers with borderline personality disorder (BPD) who were psychiatrically ...

STUDY QUESTION What are the dropout rates in lifestyle intervention programs (LIPs) for overweight and obese infertile women and can intervention- or patient-related baseline factors associated with dropout be identified in these women? SUMMARY ANSWER The median dropout rate was 24% in overweight and obese infertile women who participated in a LIP; clinical useful intervention or patient-rela...
