Note. Model taken from Sharp, Fonagy, & Allen (2012).


Figure S2.

Social cognition as a mediator in the relation between attachment and self-reported PTSD.

Note. Values on each path are regression coefficients provided by Preacher and Hayes’s (2008) test of the indirect effect. CAI = Child Attachment Interview, MASC = Movie for the Assessment of Social Cognition, YSR = Youth Self-Report, TSCC = Trauma Symptom Checklist. *p < .05.**p < .01.

Figure S3.

Social cognition as a mediator in the relation between attachment and parent-reported PTSD.

Note. Values on each path are regression coefficients provided by Preacher and Hayes’s (2008) test of the indirect effect. CAI = Child Attachment Interview, MASC = Movie for the Assessment of Social Cognition, CBCL = Child Behavior Checklist. *p < .05.

Figure S4.

Social cognition as a mediator in the relation between attachment and PTSD symptom change.

Note. Values on each path are regression coefficients provided by Preacher and Hayes’s (2008) test of the indirect effect. CAI = Child Attachment Interview, MASC = Movie for the Assessment of Social Cognition, YSR = Youth Self Report. *p < .05.

Psychiatric Medication Use / 77.11% / 94.92%
Notes. TSCC = Trauma Symptom Checklist for Children, MASC = Movie for the Assessment of Social Cognition, CAI = Child Attachment Interview. PTSD groups were created using the Youth Self-Report PTSD scale. T-scores on this scale higher than 70 made up the clinical PTSD group (n = 59, 41.5% of adolescents). T-scores on this scale of less than 65 made up the non-PTSD group (n = 83, 58.5% adolescents). Clinical diagnoses and psychiatric medication information are provided to characterize the sample but were not included in analyses. Diagnoses are not mutually exclusive.
