Comparing phase-based treatment, prolonged exposure, and skills-training for Complex Posttraumatic Stress Disorder: A randomized controlled trial.

Objective: This study examines treatment effects in STAIR Narrative Therapy (SNT), a phase-based treatment where Skills Training in Affective and Interpersonal Regulation (STAIR) precedes Narrative Therapy (NT), compared to Prolonged Exposure (PE) and to STAIR.

Method: Ninety-two adult patients diagnosed with DSM-5 PTSD and ICD-11 CPTSD following childhood abuse were randomly assigned to enhanced versions of SNT (12 group STAIR sessions + 8 individual NT sessions), PE (8-16 individual sessions), or STAIR (12 group STAIR sessions) provided in residential care. Outcome was assessed by mixed models.

Psychometric properties of the International Trauma Questionnaire (ITQ) examined in a Norwegian trauma-exposed clinical sample.

Background: The International Trauma Questionnaire (ITQ) is a self-report measure for post-traumatic stress disorder (PTSD) and complex post-traumatic stress disorder (CPTSD), corresponding to the diagnostic criteria in the International Classification of Diseases, 11th Revision (ICD-11). A 12-item version of the ITQ based on samples from English-speaking countries has been presented, and the wider generalizability to other languages needs to be examined.

Objective: The current study examines the psychometric properties of scores from a longer, preliminary 22-item version of the ITQ and the current reduced 12-item version by means of generalizability theory (G-theory) and confirmatory factor analysis (CFA).
