Personalized, Web-Based, Guided Self-Help for Patients With Medically Unexplained Symptoms in Primary Care: Protocol for a Randomized Controlled Trial

Personalized, Web-Based, Guided Self-Help for Patients With Medically Unexplained Symptoms in Primary Care: Protocol for a Randomized Controlled Trial

For HRQo L, we observed an effect size (Hedges g) of 0.66. As there was some evidence of publication bias toward larger effect sizes and because this meta-analysis also included studies with a waiting list control group, we based our calculations on an effect size of 0.5 (moderate effect). Without correcting for clustering by practice, the sample size based on an unpaired t test, given an effect size of 0.5, adopting power (1−beta) of .8, and alpha .05 2-sided, is 128.

Ecological Momentary Assessments and Automated Time Series Analysis to Promote Tailored Health Care: A Proof-of-Principle Study

Ecological Momentary Assessments and Automated Time Series Analysis to Promote Tailored Health Care: A Proof-of-Principle Study

To evaluate the outcomes of our automated analysis, we reanalyzed data that were previously analyzed in a manual analysis in a study by Rosmalen et al [18]. This data was obtained from 5 middle-aged (55-59 years old) Caucasian male patients suffering from post-myocardial infarction, recruited from screening for a psychoeducational prevention module (PEP) at the Máxima Medical Center in Eindhoven-Veldhoven, the Netherlands.
