The Effectiveness of Art Therapy in Decreasing Depressive Symptomology: A Meta-Analysis

Art therapy is an increasingly popular treatment modality with various mental health professionals; however, despite its increasing popularity and utilization, the field suffers from a continued lack of empirically validated studies that demonstrate its effectiveness. Thus, this study performed a meta-analysis on studies that utilized therapeutic art interventions with depressive symptoms in order to produce an overall effect size (ES) regarding the effectiveness of art therapy on depression. Additionally, this study attempted to determine moderating factors that might influence the magnitude of the ES. The present meta-analysis included 18 published and unpublished studies that produced a significant (p=0.001) ES of -1.10 (95% Confidence Interval (CI) of -1.64 to -0.56), thus demonstrating that art therapy has a large effect on the reduction of depression-related symptoms in participants. The results of this analysis are comparable to other meta-analyses of psychotherapeutic treatments for depression (Mazzucchelli, Kane, & Rees, 2009; Gloaguen, Cottraux, Cucherat, & Blackburn, 1998; Cuijper, van Straten, Andersson, & van Oppen, 2008). This study also covers clinically relevant issues regarding treating depression with art therapy and makes recommendations for further research.

A Meta-analytic Review of Acceptance-Based Behavioral Interventions for the Treatment of Anxiety

The relative popularity of acceptance and commitment therapy (ACT) has grown in recent years, and inspired the development of contemporary acceptance-based treatment approaches. Acceptance-based therapies differ from traditional cognitive- behavior therapy (CBT) on pragmatic grounds, the import of which implicates the purpose of therapy. CBT utilizes exposure and cognitive change techniques primarily in service of symptom change outcomes; whereas, ACT utilizes exposure and acceptance for purposes of promoting psychological flexibility in the pursuit of personal values. The purpose of this meta-analytic study was to determine the relative efficacy of acceptance- based versus symptom-change behavioral approaches with anxiety disorders and to quantify this impact. A comprehensive literature search turned up 18 studies that met inclusion criteria for this analysis. An effect size was calculated using the standardized mean gain procedure for both the acceptance-based and symptom-change approaches, along with the waitlist control groups. The results demonstrate a large effect size for the acceptance-based approach (Weighted mean ES = .83) and a medium effect size for symptom-change approach (Weighted mean ES = .60). The waitlist control groups demonstrated a small effect size (Weighted mean ES = .24). Based on this review, it is suggested that graduate and internship programs in Clinical Psychology should promote evidence-based training in the use of acceptance-inspired behavioral therapies.

A Framework for Conceptualizing Psychologically Healthy Contemplative Practice.

In recent years contemplative practices such as Zen Buddhism and yoga have become increasingly utilized in the United States (Mann et al., 2001). The most visible contemplative practice in America today is the practice of yoga. According to a 2008 market study conducted by Yoga Journal, yoga was a 5.6 billion dollar industry in America in 2008. This market study also found that 15.8 million people, or 6.9% of American adults, practice yoga (Yoga Market Study, 2008). Zen Buddhism may be less visible than yoga in popular culture, yet its presence in the United States is substantial. While exact statistics are difficult to come by, Harvard University's Pluralism Project cites that the number of practicing Buddhists in America ranges from 2.4 to 4 million people, although it is unclear how many of these individuals practice Zen, or contemplative Buddhism (Pluralism Project Statistics, 2009). The popularity of Zen in America is further evidenced by the presence of Zen centers in most major cities. The sizeable and growing presence of Buddhism in America indicates a move towards the inclusion of contemplative practice in the cultural mainstream (Pluralism Project Statistics, 2009).
