Q

Predictor classes

A

Two classes of predictors:
1) Predictors based on proximity to the traumatic event
2) Predictors based on factors more distant, eg prior adjustment/family history

Distal factors have smaller effects that the proximital
Prior event
Prior adjustment
Family history of psychopathology

Q

Unexplained variance

A

Despite identified predictors, a substantial proportion of the variability in responses to traumatic stressors remains unexplained. This suggests that unique individual and situational factors may play a crucial role in determining who develops PTSD symptoms

Q

Heterogeneity

A

Different effect sizes across a lot of studies, assuming their interchangeability for analyses may overlook significant variations. The consequences of exposure to trauma are considered more homogenous compared to the events themselves.

Q

Brewins study

A

Predictors slightly different, pattern is roughly the same.

Strongest predictors are during and right after trauma:
