Impact of pediatric burn camps on participants’ self esteem and body image: An empirical study

Quantitative as well as qualitative measures was used. To study possible effects, a pretest–posttest comparison group design with a follow-up was employed. Self-report questionnaires were used to measure self esteem and body image in a burn camp group (n = 83, 8–18 years) and in a comparison group of children with burns who did not attend a burn camp during the course of the study (n = 90, 8–18 years).

Cytokine Production by Leukocytes of Military Personnel with Depressive Symptoms after Deployment to a Combat-Zone: A Prospective, Longitudinal Study

Major depressive disorder (MDD) is frequently diagnosed in military personnel returning from deployment. Literature suggests that MDD is associated with a pro-inflammatory state. To the best of our knowledge, no prospective, longitudinal studies on the association between development of depressive symptomatology and cytokine production by peripheral blood leukocytes have been published.

An introduction to Bayesian model selection for evaluating informative hypotheses

Most researchers have specific expectations concerning their research questions. These may be derived from theory, empirical evidence, or both. Yet despite these expectations, most investigators still use null hypothesis testing to evaluate their data, that is, when analysing their data they ignore the expectations they have.

Directly evaluating expectations or testing the null hypothesis? Null hypothesis testing versus Bayesian model selection

Researchers in psychology have specific expectations about their theories. These are called informative hypothesis because they contain information about reality. Note that these hypotheses are not necessarily the same as the traditional null and alternative hypothesis.
