Objective: We tested a very brief version of the 23-item Therapeutic Factors Inventory-Short Form (TFI-S), and describe the use of Item Response Theory (IRT) for the purpose of developing short and reliable scales for group psychotherapy., Method: Group therapy patients (N = 578) completed the TFI-S on one occasion, and their data were used for the IRT analysis. Of those, 304 completed the TFI-S and other measures on more than one occasion to assess sensitivity to change, concurrent, and predictive validity of the brief version., Results: Results suggest that the new TFI-8 is a brief, reliable, and valid measure of a higher-order group therapeutic factor., Conclusion: The TFI-8 may be used for continuous process measurement and feedback to improve the functioning of therapy groups.

Objective: The aim of this paper was to synthesize the findings of qualitative studies examining the experience of individuals with mental health difficulties attending mindfulness-based interventions., Method: A meta-synthesis of 15 qualitative studies was carried out, using a thematic synthesis approach., Results: The meta-synthesis identified eight analytical themes: 'prior experiences and expectations', 'normalising and supportive process of the group', 'relating differently to thoughts and feelings', 'acceptance', 'a sense of control and choice', 'relationship with self and others', 'struggles', and 'awareness'., Conclusions: A conceptual framework is presented which accounts for the participants' experiences and suggests a process through which they renegotiate their relationship with their mental health difficulties.

Mindfulness-Based Stress Reduction (MBSR) is an experientially based group intervention empirically supported to reduce psychological symptomology. Although MBSR has shown to be an effective intervention, little is known about which facets of the intervention are important in producing positive outcomes. This study tested several aspects of mindfulness practice (total practice duration, practice frequency and practice quality) with the primary focus being on validating (i.e., predictive and convergent validity) a new measure of mindfulness practice quality (PQ-M). The PQ-M fit a two-factor solution via a Maximum Likelihood Exploratory Factor Analysis (n=99). Using longitudinal multilevel modeling on a smaller subsample (n=19), preliminary support was found for changes in practice quality over the course of the MBSR intervention. Further, change in practice quality was associated with improvements in psychological symptoms. While this study was exploratory, these findings suggest that practice quality is a relevant factor to promote positive outcomes and may guide mindfulness instructors in providing highly tailored interventions.

The Group Questionnaire (GQ) is a recently developed self-report measure of the therapeutic relationship based on Johnson and colleagues (2005) three-factor model; Positive Bonding, Positive Working, and Negative Relationship. This study validated Johnson's model with a new and extended sample and created a shorter 40-item trial version. SEM analysis of the GQ tested whether it produced the same three-factor structure found in three earlier studies with 486 participants from three populations-outpatient university counseling center, non-patient AGPA process groups, and inpatient state hospital. Results of further SEM refinements demonstrated that a final 30-item version had good fit to the three-factor model although distinct differences in response pattern were found between the three populations. Implications for future utility and clinical relevance of the GQ are discussed.

Research on the effects of progress feedback and clinician problem-solving tools on patient outcome has been limited to a few clinical problems and settings (Shimokawa, Lambert, & Smart, 2010). Although these interventions work well in outpatient settings their effects so far have not been investigated with eating-disordered patients or in inpatient care. In this study, the effect of providing feedback interventions was investigated in a randomized clinical trial involving 133 females diagnosed with anorexia nervosa, bulimia nervosa, or eating disorders not otherwise specified. Comparisons were made between the outcomes of patients randomly assigned to either treatment-as-usual (TAU) or an experimental condition (Fb) within therapists (the same therapists provided both treatments). Patients in the Fb condition more frequently experienced clinically significant change than those who had TAU (52.95% vs. 28.6%). Similar trends were noted within diagnostic groups. In terms of pre to post change in mental health functioning, large effect sizes favored Fb over TAU. Patients' BMI improved substantially in both TAU and the feedback condition. The effects of feedback were consistent with past research on these approaches although the effect size was smaller in this study. Suggestions for further research are delineated.

The purpose of the study was to compare the effectiveness of 4-day versus 5-day day hospital (DH) treatment and to document effectiveness based on a large sample size. Participants were 801 patients, diagnosed with an eating disorder, who participated in DH treatment from 1985 to 2009. The study followed a sequential cohort ABA design. Higher intensity DH was associated with higher rates of abstinence from bingeing and vomiting and larger improvements in depression and body dissatisfaction. Higher intensity DH provided no consistent advantage in rates of weight restoration or improvement on other indices of psychological functioning. These findings suggest that the optimal intensity of treatment may vary depending on treatment goals, but 5-day DH is recommended for eating disorders.
