Therapist responsiveness in psychotherapy: Introduction to the special section.

Therapist responsiveness denotes that therapists provide therapeutic interventions within an emerging context of client manifestations and moment-by-moment internal and external changes. So far, psychotherapy research on explaining how therapy works falls short of operationalizing the sequence of events constituted by therapist responsiveness. The present special section of Psychotherapy Research addresses this conceptual and methodological gap and proposes six original contributions, using several validated assessment protocols, both from a quantitative and qualitative viewpoint, to study therapist responsiveness in psychotherapy.

Core outcome sets for trials of interventions to prevent and to treat multimorbidity in adults in low and middle-income countries: the COSMOS study.

Introduction: The burden of multimorbidity is recognised increasingly in low- and middle-income countries (LMICs), creating a strong emphasis on the need for effective evidence-based interventions. Core outcome sets (COS) appropriate for the study of multimorbidity in LMICs do not presently exist. These are required to standardise reporting and contribute to a consistent and cohesive evidence-base to inform policy and practice.
