Assessing the validity and responsiveness of a generic preference quality of life measure in the context of posttraumatic stress disorder.

Purpose: There is limited research exploring the usefulness of generic preference-based quality of life (GPQoL) measures used to facilitate economic evaluation in the context of posttraumatic stress disorder (PTSD). The aim of the current study was to explore the validity and responsiveness of a common GPQoL measure (Assessment of Quality of Life 8 Dimension [AQoL-8D]) in relation to a PTSD condition-specific outcome measure (Posttraumatic Stress Disorder Checklist for the DSM-5 [PCL-5]).

Method: This aim was investigated in a sample of individuals (N = 147) who received trauma-focused cognitive-behavioural therapies for posttraumatic stress disorder.

Client Versus Clinicians' Standards of Clinically Meaningful Change and the Effects of Treatment Expectations on Therapeutic Outcomes in Individuals With Posttraumatic Stress Disorder.

There is limited research on the concordance between client perceptions and clinician standards of the degree of symptom change required to achieve meaningful therapeutic improvement. This was investigated in an adult sample (N = 147) who received trauma-focused cognitive-behavioral therapies for posttraumatic stress disorder (PTSD). We examined whether clients' benchmarks of change were related to actual outcomes and the relationship between client expectations and their treatment outcomes.
