In it, she reviews a number of studies done to examine the effect on cancer patients of psychological intervention, obviously hoping to report that the interventions had significantly increased survival rates, quality of life, or both, but the findings are not particularly hopeful.

This is not, as I understand it, statistically significant. Andersen suggests models for new studies that might provide better results. Andersen says that "intervention studies face considerable manpower, logistic, collaborative, and funding challenges. This review suggests that when under-piloted, -manned, - organized, or -powered, there are methodologic and/or statistical problems, not the least of which is accrual and retention" (Andersen, 2002, p. 603). This then should be the first priority: to design a study that will accrue and retain a large enough patient sample to give results that can be replicated and validated. "Appropriate description and data must be provided for both" [accrual and retention]. Furthermore, any such study, regardless of its range, must be "accompanied by a rigorous statistical analysis (and not one limited by low power due to small sample size) to rule out biases that might be correlated with ...
