Background Although self‐efficacy (SE) and outcome expectancy (OE) have been well researched as predictors of outcome, few studies have investigated changes in these variables across treatments. We evaluated changes in OE and SE throughout treatment as predictors of outcomes in a large sample with panic disorder, generalized anxiety disorder, social anxiety disorder, or posttraumatic stress disorder. We hypothesized that increases in SE and OE would predict reductions in anxiety and depression as well as improvement in functioning. Methods Participants (mean age = 43.3 years, SD = 13.2, 71.1% female, 55.5% white) were recruited from primary care centers throughout the United States and were randomized to receive either Coordinated Anxiety Learning and Management (CALM) treatment – composed of cognitive behavioral therapy, psychotropic medication, or both – or usual care. SE and OE ratings were collected at each session for participants in the CALM treatment (n = 482) and were entered into a structural equation model as predictors of changes in Brief Symptom Inventory, Anxiety Sensitivity Index, Patient Health Questionnaire (PHQ), and Sheehan Disability Scale outcomes at 6, 12, and 18 months after baseline. Results The best‐fitting models predict symptom levels from OE and SE and not vice versa. The slopes and intercept of OE significantly predicted change in each outcome variable except PHQ‐8. The slope and intercept of SE significantly predicted change in each outcome variable. Conclusion Over and above absolute level, increases in SE and OE were significant predictors of decreases in symptoms and increases in functioning. Implications for treatment are discussed, as well as future directions of research.

Objective: The objective of this study was to examine the relative impact of anxiety disorders and major depression on functional status and health-related quality of life of primary care outpatients. Method: Four hundred eighty adult outpatients at an index visit to their primary care provider were classified by structured diagnostic interview as having anxiety disorders (panic disorder with or without agoraphobia, social phobia, and posttraumatic stress disorder, generalized anxiety disorder was also assessed in a subset) with or without major depression. Functional status, sick days from work, and health-related quality of life (including a preference-based measure) were assessed using standardized measures adjusting for the impact of comorbid medical illnesses. Relative impact of the various anxiety disorders and major depression on these indices was evaluated. Results: In multivariate regression analyses simultaneously adjusting for age, sex, number of chronic medical conditions, education, and/or poverty status, each of major depression, panic disorder, posttraumatic stress disorder, and social phobia contributed independently and relatively equally to the prediction of disability and functional outcomes. Generalized anxiety disorder had relatively little impact on these indices when the effects of comorbid major depression were considered. Overall, anxiety disorders were associated with substantial decrements in preference-based health states. Conclusions: These observations demonstrate that the presence of each of 3 common anxiety disorders (ie, panic disorder, posttraumatic stress disorder, and social phobia)-over and above the impact of chronic physical illness, major depression, and other socioeconomic factors-contributes in an approximately additive fashion to the prediction of poor functioning, reduced health-related quality of life, and more sick days from work. Greater awareness of the deleterious impact of anxiety disorders in primary care is warranted.

Background
Bottom-up, clinician-conceived and directed clinical intervention research, coupled with collaboration from researcher experts, is conceptually endorsed by the participatory research movement. This report presents the findings of an evaluation of a program in the Veterans Health Administration meant to encourage clinician-driven research by providing resources believed to be critical. The evaluation focused on the extent to which funded projects: maintained integrity to their original proposals; were methodologically rigorous; were characterized by collaboration between partners; and resulted in sustained clinical impact.
Methods
Researchers used quantitative (survey and archival) and qualitative (focus group) data to evaluate the implementation, evaluation, and sustainability of four clinical demonstration projects at four sites. Fourteen research center mentors and seventeen clinician researchers evaluated the level of collaboration using a six-dimensional model of participatory research.
Results
Results yielded mixed findings. Qualitative and quantitative data suggested that although the process was collaborative, clinicians' prior research experience was critical to the quality of the projects. Several challenges were common across sites, including subject recruitment, administrative support and logistics, and subsequent dissemination. Only one intervention achieved lasting clinical effect beyond the active project period. Qualitative analyses identified barriers and facilitators and suggested areas to improve sustainability.
Conclusions
Evaluation results suggest that this participatory research venture was successful in achieving clinician-directed collaboration, but did not produce sustainable interventions due to such implementation problems as lack of resources and administrative support.

In this study, we examined the sociocultural factors underlying infant feeding practices. We conducted four focus groups with 19 Latina mothers of children 0 to 2 years of age enrolled in Early Head Start programs in the United States over a 1-year period. We found these mothers considered both science- and family-based feeding recommendations. However, advice from family was often inconsistent with science- and nutrition-based recommended feeding practices. In the interest of showing respect and preserving harmonious relationships, some mothers accepted family advice instead of recommended practices while others employed strategies to follow recommended practices without offending. Nutrition educators need to consider the intersection of macro, organizational, and community factors with micro-level processes in shaping the implementation of recommended feeding practices within family systems. Nutrition interventions for Latino families should capitalize on Latina mothers’ strategies for navigating multiple information sources while preserving cultural values and family relationships.

Background
Although for more than a decade healthcare systems have attempted to provide evidence-based mental health treatments, the availability and use of psychotherapies remains low. A significant need exists to identify simple but effective implementation strategies to adopt complex practices within complex systems of care. Emerging evidence suggests that facilitation may be an effective integrative implementation strategy for adoption of complex practices. The current pilot examined the use of external facilitation for adoption of cognitive behavioral therapy (CBT) in 20 Department of Veteran Affairs (VA) clinics.
Methods
The 20 clinics were paired on facility characteristics, and 23 clinicians from these were trained in CBT. A clinic in each pair was randomly selected to receive external facilitation. Quantitative methods were used to examine the extent of CBT implementation in 10 clinics that received external facilitation compared with 10 clinics that did not, and to better understand the relationship between individual providers' characteristics and attitudes and their CBT use. Costs of external facilitation were assessed by tracking the time spent by the facilitator and therapists in activities related to implementing CBT. Qualitative methods were used to explore contextual and other factors thought to influence implementation.
Results
Examination of change scores showed that facilitated therapists averaged an increase of 19% [95% CI: (2, 36)] in self-reported CBT use from baseline, while control therapists averaged a 4% [95% CI: (-14, 21)] increase. Therapists in the facilitated condition who were not providing CBT at baseline showed the greatest increase (35%) compared to a control therapist who was not providing CBT at baseline (10%) or to therapists in either condition who were providing CBT at baseline (average 3%). Increased CBT use was unrelated to prior CBT training. Barriers to CBT implementation were therapists' lack of control over their clinic schedule and poor communication with clinical leaders.
Conclusions
These findings suggest that facilitation may help clinicians make complex practice changes such as implementing an evidence-based psychotherapy. Furthermore, the substantial increase in CBT usage among the facilitation group was achieved at a modest cost.

Background
Investigators recently tested the effectiveness of a collaborative-care intervention for anxiety disorders: Coordinated Anxiety Learning and Management(CALM) []) in 17 primary care clinics around the United States. Investigators also conducted a qualitative process evaluation. Key research questions were as follows: (1) What were the facilitators/barriers to implementing CALM? (2) What were the facilitators/barriers to sustaining CALM after the study was completed?
Methods
Key informant interviews were conducted with 47 clinic staff members (18 primary care providers, 13 nurses, 8 clinic administrators, and 8 clinic staff) and 14 study-trained anxiety clinical specialists (ACSs) who coordinated the collaborative care and provided cognitive behavioral therapy. The interviews were semistructured and conducted by phone. Data were content analyzed with line-by-line analyses leading to the development and refinement of themes.
Results
Similar themes emerged across stakeholders. Important facilitators to implementation included the perception of \"low burden\" to implement, provider satisfaction with the intervention, and frequent provider interaction with ACSs. Barriers to implementation included variable provider interest in mental health, high rates of part-time providers in clinics, and high social stressors of lower socioeconomic-status patients interfering with adherence. Key sustainability facilitators were if a clinic had already incorporated collaborative care for another disorder and presence of onsite mental health staff. The main barrier to sustainability was funding for the ACS.
Conclusions
The CALM intervention was relatively easy to incorporate during the effectiveness trial, and satisfaction was generally high. Numerous implementation and sustainability barriers could limit the reach and impact of widespread adoption. Findings should be interpreted with the knowledge that the ACSs in this study were provided and trained by the study. Future research should explore uptake of CALM and similar interventions without the aid of an effectiveness trial.

Objectives. We conducted a theoretically guided study of access to inpatient or residential treatment among a probability sample of homeless adults with alcohol or drug use disorders in Houston, Texas. Methods. This study used a cross-sectional, retrospective design with data collected from a multistage random sample of 797 homeless adults age 18 or older who were living in Houston shelters and streets in 1996. Structured, face-to-face interviews produced screening diagnoses for alcohol and drug use disorders, treatment use data, and candidate predictors of treatment use. Logistic and linear regression analyses were performed on the subset of 326 homeless persons with either alcohol or drug use disorder. Results. 27.5% of persons with substance use disorder had accessed inpatient or residential treatment during the past year. Controlling for additional need factors such as comorbidity, persons having public health insurance and a history of treatment for substance problems had greater odds of receiving at least one night of treatment. Contrary to expectation, contact with other service sectors was not predictive of treatment access. Schizophrenia and having a partner appeared to hinder access. Greater need for treatment was associated with fewer nights of treatment, suggesting retention difficulties. Conclusions. This study adds to previous findings on access to health care among homeless persons and highlights a pattern of disparities in substance abuse treatment access. Health insurance is important, but enhancing access to care involves more than economic considerations if homeless persons are to receive the treatment they need. Referral relationships across different service sectors may require strengthening.

Background The current study tested whether perceived social support serves as a mediator of anxiety and depressive symptom change following evidence‐based anxiety treatment in the primary care setting. Gender, age, and race were tested as moderators. Methods Data were obtained from 1004 adult patients (age M = 43, SD = 13; 71% female; 56% White, 20% Hispanic, 12% Black) who participated in a randomized effectiveness trial (coordinated anxiety learning and management [CALM] study) comparing evidence‐based intervention (cognitive‐behavioral therapy and/or psychopharmacology) to usual care in the primary care setting. Patients were assessed with a battery of questionnaires at baseline, as well as at 6, 12, and 18 months following baseline. Measures utilized in the mediation analyses included the Abbreviated Medical Outcomes (MOS) Social Support Survey, the Brief Symptom Index (BSI)–Somatic and Anxiety subscales, and the Patient Health Questionnaire (PHQ‐9). Results There was a mediating effect over time of perceived social support on symptom change following treatment, with stronger effects for 18‐month depression than anxiety. None of the mediating pathways were moderated by gender, age, or race. Conclusions Perceived social support may be central to anxiety and depressive symptom changes over time with evidence‐based intervention in the primary care setting. These findings possibly have important implications for development of anxiety interventions.

Background Generalized anxiety disorder (GAD) and major depressive disorder (MDD) are highly comorbid. A possible explanation is that they share four symptoms according to the Diagnostic and Statistical Manual of Mental Disorders—Fourth Edition—Text Revision (DSM‐IV‐TR). The present study addressed the symptom overlap of people meeting DSM‐IV‐TR diagnostic criteria for GAD, MDD, or both to investigate whether comorbidity might be explained by overlapping diagnostic criteria. Methods Participants (N = 1,218) were enrolled in the Coordinated Anxiety Learning and Management study (a randomized effectiveness clinical trial in primary care). Hypotheses were (1) the comorbid GAD/MDD group endorses the overlapping symptoms more than the nonoverlapping symptoms, and (2) the comorbid GAD/MDD group endorses the overlapping symptoms more than GAD only or MDD only groups, whereas differences would not occur for nonoverlapping symptoms. Results The overlapping GAD/MDD symptoms were endorsed more by the comorbid group than the MDD group but not the GAD group when covarying for total symptom endorsement. Similarly, the comorbid group endorsed the overlapping symptoms more than the nonoverlapping symptoms and did not endorse the nonoverlapping symptoms more than the GAD or MDD groups when covarying for total symptom endorsement. Conclusions The results suggest that comorbidity of GAD and MDD is strongly influenced by diagnostic overlap. Results are discussed in terms of errors of diagnostic criteria, as well as models of shared psychopathology that account for diagnostic criteria overlap.
