In factor analysis, why does the commonly used CNG method nearly always land at 3 factors when applied to anx/depr/ocd scales?
TLDR: There tends to be one factor/component with a large eigenvalue. In these cases, almost inevitably and somewhat arbitrarily, the procedure selects 3 factors 👇

Why do some people feel a “not-quite-right” sensation before they pick their skin?
The first ever systematic review on interoception and skin-picking disorder explores how bodily cues and affective touch might help explain the urge.

Sookud and colleagues found that individuals with higher compulsivity and intrusive thoughts develop a less certain internal understanding of the external world, and this mediates the link between symptoms and goal-directed behaviors.
Impaired goal-directed planning in transdiagnostic compulsivity is explained by uncertainty about learned task structure
Diminished use of goal-directed (“model-based”) decision-making is a hallmark of transdiagnostic
compulsivity, promoting an over-reliance on inflexible and habitual behaviours. However,

Preschoolers who find uncertainty hard to handle may be more prone to anxiety later in life, but it’s not that simple.
New research explores how intolerance of uncertainty at age 4 links to anxiety, depression & behaviour problems up to age 10.

Taken together, our results advance our understanding of the dynamics of fun in realistic environments. They also emphasize the importance of using realistic, game-like environments together with highly-controlled experiments to advance our theories of human motivation & learning.
