From lists of behaviour change techniques (BCTs) to structured hierarchies: comparison of two methods of developing a hierarchy of BCTs.

Objectives: Behaviour change technique (BCT) Taxonomy v1 is a hierarchically grouped, consensus-based taxonomy of 93 BCTs for reporting intervention content. To enhance the use and understanding of BCTs, the aims of the present study were to (1) quantitatively examine the 'bottom-up' hierarchical structure of Taxonomy v1, (2) identify whether BCTs can be reliably mapped to theoretical domains using a 'top-down' theoretically driven approach, and (3) identify any overlap between the 'bottom-up' and 'top-down' groupings.

Methods And Design: The 'bottom-up' structure was examined for higher-order groupings using a dendrogram derived from hierarchical cluster analysis.

The recognition of the personality disorders among young people.

Background: Previous research suggests that mental health literacy regarding the personality disorders is low, with few disorders being recognised.

Aims: The current study aimed to examine the effect of a background in psychology as a predictor of knowledge of the personality disorders.

Methods: An opportunistic sample of 165 participants (mean age = 30.
