Does Researcher Allegiance Bias Outcomes in Psychotherapy Research? A Quasi-Experimental Secondary Analysis.

Researchers who conduct studies comparing the efficacy of two treatments often find that their preferred treatment outperforms the comparison treatment. This finding has been labelled the allegiance association. Although this association is robust, it is unclear whether it reflects an allegiance bias on the part of the researchers or whether it is noncausal, with researchers being allied to the more effective treatments.

Construction and preliminary validation of Triarchic Psychopathy Scales from the HEXACO-100.

According to the triarchic model, psychopathy encompasses 3 distinct dispositional constructs: boldness, meanness, and disinhibition. Although the Triarchic Psychopathy Measure was designed to assess these 3 constructs, researchers have developed alternative triarchic scales using both omnibus measures of general personality and existing psychopathy scales. The components of the HEXACO model of personality may be especially capable of characterizing the dimensions of the triarchic model of psychopathy.
