Even when raters demonstrate agreement in the use of a measure, limited score variability or violation of often-ignored statistical assumptions can result in lower reliability estimates than intuitively expected. This article uses data drawn from two randomized controlled trials of schema therapy and cognitive behavioral therapy for the treatment…

When conducting interviews with multilinguals, researchers make (often invisible) decisions about the interview language(s). Whilst the research design may require a particular approach in some cases, linguists generally recommend giving participants a choice or interviewing them in their first language. There are ethical and methodological…

Delay discounting (DD) procedures are emerging as an important new method for psychotherapy researchers. In this paper a framework for conceptualizing existing, seemingly discrepant, research findings on termination is introduced and new directions for research are described. To illustrate the value of a DD framework, the common psychotherapy…

The long-standing divide between research and practice in clinical psychology has received increased attention in view of the development of evidence-based interventions and practice and public interest, oversight, and management of psychological services. The gap has been reflected in concerns from those in practice about the applicability of…

Both researchers and practitioners need to know more about how laboratory treatment protocols translate to real-world practice settings and how clinical innovations can be systematically tested and communicated to a skeptical scientific community. The single-case time-series study is well suited to opening a productive discourse between practice…

In the past two decades, numerous meta-analyses have been published that examine the question of psychotherapy equivalence. Hunsley and Di Giulio (2002) critically reviewed this literature and concluded that there was abundant evidence that the Dodo bird verdict of equivalence across psychotherapies is false. In this article, we summarize and…

Bridging the gap between lab and clinic has become a rallying cry for a generation of treatment researchers, and identifying and overcoming barriers to successful dissemination of best-practice treatment has become a major public mental health priority. In this review, the authors argue that a key limit to accomplishing this goal may be found back…

Psychoanalysis and child psychotherapy have traditionally sought to describe their relationship to science in a variety of ways. As a consequence, different strands of the research programme are underpinned by divergent methodological and epistemic assumptions. The perceived incommensurability of these positions sometimes hinders the development…

Over the past 25 years, meta-analysis has assumed a significant role in the synthesis of counseling and psychotherapy research through the evaluation and interpretation of the results of multiple studies. An examination of four widely recognized rehabilitation counseling journals, however, reveals that only one meta-analysis (Bolton & Akridge,…

Integrating theory, research, and practical applications, this book provides a comprehensive examination of defense mechanisms and their role in both normal development and psychopathology. The author describes how children and adults mobilize specific kinds of defenses to maintain their psychological equilibrium and preserve self-esteem,…
