RESUMEN

This study identifies the unique contributions of asthma severity, symptoms, control and generic measures of quality of life (QoL) to asthma-specific QoL, as measured by the 12-item RAND Negative Impact of Asthma on Quality of Life scale (RAND-IAQL-12).Using a sample of 2032 adults with asthma, we conducted multiple regression analyses that sequentially examined hypothesised predictors of asthma-specific QoL. The change in variance accounted for and total unique variance accounted for is calculated as hypothesised predictors are added in each step.Our results indicate that asthma severity and asthma symptoms are strong predictors of asthma-specific QoL only when not controlling for aspects of asthma control. In regression models that include other aspects of asthma control, the contributions of both asthma symptoms and severity were substantially reduced, with asthma control and aspects of QoL related to social roles and activities emerging as the strongest predictors of asthma-specific QoL.These findings suggest that researchers measuring the impact of asthma on QoL should also consider the importance of asthma control as measured by the RAND Asthma Control Measure (RAND-ACM) and generic QoL scales that measure aspects of daily life that are uniquely affected by asthma.

RESUMEN

BACKGROUND: In response to recommendations from the 2010 National Institutes of Health Asthma Outcomes Workshop, we developed a system for measuring the negative impact of asthma on quality of life (QoL), which was referred to as the RAND Negative Impact of Asthma on Quality of Life (RAND-IAQL) item bank. The bank contains 65 items that focus on the patient's perception of the impact or bother of asthma on his or her life. OBJECTIVE: Evidence for the validity of 2 short forms, the RAND-IAQL 4-item and 12-item Short Forms, from the bank is presented. METHODS: Using a sample of 2032 adults with asthma, we validated our short forms against the Asthma Quality of Life Questionnaire-Marks (AQLQ-M), the Asthma Control Test, and generic measures of QoL developed by the Patient-reported Outcomes Measurement Information System (PROMIS). Discriminant validity was examined by comparing scores of respondents who differed according to multiple health indicators. RESULTS: Our sample ranged in age from 18 to 99 years (mean, 43 years), with 14% Hispanic, 11% Asian, 19% African American, and 56% non-Hispanic white race/ethnicity. Men had a significantly worse impact of asthma on QoL than women. The impact of asthma on QoL was greatest in African American and Hispanic subjects compared with that seen in non-Hispanic white subjects. Our measures correlated highly with the AQLQ-M and more strongly with the PROMIS global physical than mental scales. They differentiated between adults with asthma according to their perceived severity, level of control, presence or absence of exacerbations, and physical comorbidity. CONCLUSION: The RAND-IAQL item bank, measuring the impact of asthma on QoL, will complement other patient-reported outcomes, such as measures of asthma symptoms, functioning, and control.

RESUMEN

Patient-based measures for asthma control are important in assessing the worldwide impact of this highly prevalent chronic illness. We sought to refine an asthma symptom scale that RAND had previously developed to shorten it and validate it further, as well as reflect updated international expert definitions of asthma control. We conducted rigorous psychometric testing of new and adapted self-administered survey items in a sample of 2032 adults with asthma. The reliability and preliminary validity of the resulting measure, henceforth referred to as the RAND Asthma Control Measure (RAND-ACM), matched or exceeded that of the original RAND measure and others in the literature. RAND-ACM scores for worse asthma control were significantly associated with worse asthma-related quality of life, increased asthma-related healthcare use, Hispanic ethnicity and lower educational level. Evidence for internal consistency was strong with a Cronbach's α of 0.84. We also found adequate concordance between the RAND-ACM and the Global Initiative for Asthma categories of "uncontrolled", "partly controlled" and "controlled" asthma. The RAND-ACM, a five-item self-reported asthma control survey measure, performs well in a large ethnically-diverse sample of US adults with asthma and provides a cost-free alternative to other asthma control measures currently available.

RESUMEN

PURPOSE: A key goal in asthma treatment is improvement in quality of life (QoL), but existing measures often confound QoL with symptoms and functional impairment. The current study addresses these limitations and the need for valid patient-reported outcome measures by using state-of-the-art methods to develop an item bank assessing QoL in adults with asthma. This article describes the process for developing an initial item pool for field testing. METHODS: Five focus group interviews were conducted with a total of 50 asthmatic adults. We used "pile sorting/binning" and "winnowing" methods to identify key QoL dimensions and develop a pool of items based on statements made in the focus group interviews. We then conducted a literature review and consulted with an expert panel to ensure that no key concepts were omitted. Finally, we conducted individual cognitive interviews to ensure that items were well understood and inform final item refinement. RESULTS: Six hundred and sixty-one QoL statements were identified from focus group interview transcripts and subsequently used to generate a pool of 112 items in 16 different content areas. CONCLUSIONS: Items covering a broad range of content were developed that can serve as a valid gauge of individuals' perceptions of the effects of asthma and its treatment on their lives. These items do not directly measure symptoms or functional impairment, yet they include a broader range of content than most existent measures of asthma-specific QoL.

RESUMEN

INTRODUCTION: Although health screenings offer timely detection of health conditions and enable early intervention, adoption is often poor. How might financial interventions create the necessary incentives and resources to improve screening in primary care settings? This systematic review aimed to answer this question. METHODS: Peer-reviewed studies published between 2000 and 2023 were identified and categorized by the level of intervention (practice or individual) and type of intervention, specifically alternative payment models (APMs), fee-for-service (FFS), capitation, and capital investments. Outcomes included frequency of screening, performance/quality of care (e.g., patient satisfaction, health outcomes), and workflow changes (e.g., visit length, staffing). RESULTS: Of 51 included studies, a majority focused on practice-level interventions (n=32), used APMs (n=41) that involved payments for achieving key performance indicators (KPIs; n=31) and were of low or very low strength of evidence based on GRADE criteria (n=42). Studies often included screenings for cancer (n=32), diabetes care (n=18), and behavioral health (n=15). KPI payments to both practices and individual providers corresponded with increased screening rates, whereas capitation and provider-level FFS models yielded mixed results. A large majority of studies assessed changes in screening rates (n=48) with less focus on quality of care (n=11) or workflow changes (n=4). DISCUSSION: Financial mechanisms can enhance screening rates with evidence strongest for KPI payments to both practices and individual providers. Future research should explore the relationship between financial interventions and quality of care, in terms of both clinical processes and patient outcomes, as well as the role of these interventions in shaping care delivery.

RESUMEN

INTRODUCTION: Adverse childhood experiences (ACEs) are strongly correlated with many of the most common causes of preventable illness, preventable death, and health disparities. In January 2020, California launched the first statewide initiative to integrate ACE screening throughout its Medicaid system. A key element of the initiative was the California ACEs Learning and Quality Improvement Collaborative, a 48-clinic, 16-month learning collaborative. This evaluation aimed to determine whether developing a trauma-informed environment of care was associated with uptake of ACE screening. METHODS: Participants included 40 of 48 clinics that participated in the statewide learning collaborative. Clinics completed an assessment of progress in 5 essential components of trauma-informed health care at baseline and 1-year follow-up. Clinics tracked data on ACE screens completed on an ongoing basis and submitted data quarterly. A hierarchical linear model was used to examine the association between change in readiness for trauma-informed health care and change in quarterly screens. RESULTS: Readiness for trauma-informed health care increased for all participating clinics over the course of the learning collaborative. The average number of quarterly screens also increased, with considerable variability among clinics. Clinics with larger increases in readiness for trauma-informed health care had larger increases in quarterly screens. DISCUSSION: The findings align with long-standing recommendations for trauma screening to occur in the context of trauma-informed environments of care. CONCLUSION: A trauma-informed clinic is the foundation for successful adoption of ACE screening. ACE screening initiatives should include education and sufficient support for clinics to embrace a trauma-informed systems change process.

RESUMEN

WeRise-a component of the Los Angeles County Department of Mental Health's (LACDMH's) broader campaign, WhyWeRise-is an annual set of events targeting prevention and early intervention for mental health challenges. This evaluation indicates that WeRise events successfully reached groups of Los Angeles County residents particularly in need of mental health support, such as youth; mobilized them around mental health issues; and may have boosted awareness of mental health resources in the county. Perceptions of the events were very positive, with the vast majority saying that the event they attended connected them with resources and community, showed some of the strengths of their community, and empowered them to take care of their well-being.

RESUMEN

WhyWeRise is a social marketing campaign conducted by the Los Angeles County Department of Mental Health (LACDMH) to promote community engagement with mental health issues, reduce barriers to care, and increase awareness of how to seek mental health care. LACDMH has partnered with the Los Angeles Dodgers for several years to expand the reach of the campaign to the Major League Baseball team's audience and spread the WhyWeRise messages to the Dodgers' extensive Hispanic fan base-a key county demographic with attitudes toward mental illness that sometimes differ from those of other ethnic groups. The LACDMH/Dodgers campaign focused on awareness of resources and stigma reduction among Hispanic county residents. This study builds on prior RAND work and provides an evaluation of the reach of the 2022 Dodgers campaign overall and a focus on the reach to (and potential impact of outreach on) attendees of 2022 Dodger games. Results indicate that the Dodgers campaign reached a substantial percentage of Los Angeles County residents: 12 percent of adults and 27 percent of youth reported exposure to the campaign, translating to more than 800,000 adults and more than 400,000 youth reached. The campaign was effective in targeting Hispanic- or Latino-identifying residents, who made up 71 percent of youth who were campaign-exposed and 58 percent of adults exposed. In summary, there is evidence that the Dodgers campaign successfully reached Los Angeles County residents, particularly Hispanics and young adults, and that those reached were more aware of key county mental health resources.

RESUMEN

OBJECTIVE: Mental health emergency hotlines provide clinical supports and connection to services. This scoping review describes the current literature on hotlines in the United States, including which populations they do and do not reach, typical call volumes and engagement levels, barriers to and facilitators of implementation, and common call outcomes. The review also identifies gaps in the literature and presents recommendations. METHODS: A systematic search of peer-reviewed articles on U.S.-based telephone, text, and chat hotlines published between January 2012 and December 2021 retrieved 1,049 articles. In total, 96 articles met criteria for full-text review, of which 53 met full inclusion criteria. RESULTS: Approximately half of the included studies (N=25) focused on descriptive information of callers, most of whom were females, younger adults, and White; veteran hotlines typically reached older men. Common reasons for calling were suicidality, depression, and interpersonal problems. Of studies examining intervention effects (N=20), few assessed hotlines as interventions (N=6), and few evaluated caller behavioral outcomes (N=4), reporting reduced distress and suicidality among callers after hotline engagement. However, these studies also suggested areas for improvement, including reaching underrepresented high-risk populations. Six studies reported implementation needs, such as investments in data collection and evaluation, staff training, and sustainable funding. CONCLUSIONS: Hotlines appear to be more effective at reaching some populations than others, indicating that more intensive outreach efforts may be necessary to engage underrepresented high-risk populations. The findings also indicated limited evidence on the relationship between use of hotlines-particularly local text and chat hotlines-and caller outcomes, highlighting an area for further investigation.

RESUMEN

Psychiatric and substance use disorder (SUD) treatment beds are essential infrastructure for meeting the needs of individuals with behavioral health conditions. However, not all psychiatric and SUD beds are alike: They represent infrastructure within different types of facilities. For psychiatric beds, these vary from acute psychiatric hospitals to community residential facilities. For SUD treatment beds, these vary from facilities offering short-term withdrawal management services to others offering longer duration residential detoxification services. Different settings also serve clients with different needs. For example, some clients have high-acuity, short-term needs; others have longer-term needs and may return for care on multiple occasions. California's Merced, San Joaquin, and Stanislaus Counties, like other counties throughout the United States, have sought to assess shortages in psychiatric and SUD treatment beds. In this study, the authors estimated psychiatric bed and residential SUD treatment capacity, need, and shortages for adults and children and adolescents at various levels of care: acute, subacute, and community residential services for psychiatric treatment and SUD treatment service categories defined by American Society of Addiction Medicine clinical guidelines. Drawing from various data sets, literature review findings, and facility survey responses, the authors computed the number of beds required-at each level of care-for adults and children and adolescents and identified hard-to-place populations. The authors draw from these findings to offer Merced, San Joaquin, and Stanislaus Counties recommendations to help ensure all their residents, especially nonambulatory individuals, have access to the behavioral health care that they need.

RESUMEN

988, a national mental health emergency hotline number, went live throughout the United States in July 2022. 988 connects callers to the 988 Crisis & Suicide Lifeline, previously known as the National Suicide Prevention Lifeline. The transition to the three-digit number aimed to respond to a growing national mental health crisis and to expand access to crisis care. We examined preparedness throughout the U.S. for the transition to 988. In February and March 2022, we administered a national survey of state, regional, and county behavioral health program directors. Respondents (n = 180) represented jurisdictional coverage of 120 million Americans. We found that communities throughout the U.S. appeared ill-prepared for rollout of 988. Fewer than half of respondents reported their jurisdictions were 'somewhat' or 'very' prepared for 988 in terms of financing (29%), staffing (41%), infrastructure (41%), or service coordination (47%). Counties with higher representation of Hispanic/Latinx individuals were less likely to report being prepared for 988 in terms of staffing (OR: 0.62, 95 %CI: 0.45, 0.86) and infrastructure (OR: 0.68, 95 %CI: 0.48, 0.98). In terms of existing services, sixty percent of respondents reported a shortage of crisis beds and fewer than half reported availability of short-term crisis stabilization programs in their jurisdictions. Our study highlights components of local, regional, and state behavioral health systems in the U.S. that require greater investments to support 988 and mental health crisis care.

RESUMEN

Background: Adverse childhood experiences (ACEs) can have harmful, long-term health effects. Although primary care providers (PCPs) could help mitigate these effects, no studies have reviewed the impacts of ACE training, screening, and response in primary care. Methods: This systematic review searched four electronic databases (PubMed, Web of Science, APA PsycInfo, CINAHL) for peer-reviewed articles on ACE training, screening, and/or response in primary care published between Jan 1, 1998, and May 31, 2023. Searches were limited to primary research articles in the primary care setting that reported provider-related outcomes (knowledge, confidence, screening behavior, clinical care) and/or patient-related outcomes (satisfaction, referral engagement, health outcomes). Summary data were extracted from published reports. Findings: Of 6532 records, 58 met inclusion criteria. Fifty-two reported provider-related outcomes; 21 reported patient-related outcomes. 50 included pediatric populations, 12 included adults. A majority discussed screening interventions (n = 40). Equal numbers (n = 25) discussed training and clinical response interventions. Strength of evidence (SOE) was generally low, especially for adult studies. This was due to reliance on observational evidence, small samples, and self-report measures for heterogeneous outcomes. Exceptions with moderate SOE included the effect of training interventions on provider confidence/self-efficacy and the effect of screening interventions on screening uptake and patient satisfaction. Interpretation: Primary care represents a potentially strategic setting for addressing ACEs, but evidence on patient- and provider-related outcomes remains scarce. Funding: The California Department of Health Care Services and the Office of the California Surgeon General.

RESUMEN

WhyWeRise is a social marketing campaign conducted by the Los Angeles County Department of Mental Health (LACDMH) to promote community engagement with mental health issues along a continuum from self-care to professional treatment services, reduce barriers to care, and increase awareness of how to seek mental health care. In 2020 and 2021, LACDMH partnered with the Los Angeles Dodgers to expand the reach of the campaign to the Major League Baseball team's audience and spread the WhyWeRise messages to the Dodgers' extensive Hispanic fan base-a key county demographic with attitudes toward mental illness that sometimes differ from those of other ethnic groups. The LACDMH/Dodgers campaign focused on awareness of resources and stigma-reduction among Hispanic county residents. This study builds on prior RAND work and provides an evaluation of the reach of the 2020 and 2021 Dodgers campaign overall and a focus on the reach and potential impact of outreach to attendees of 2021 Dodger games.

RESUMEN

Psychiatric beds are essential infrastructure for meeting the needs of individuals with mental health conditions. However, not all psychiatric beds are alike: They represent infrastructure within different types of facilities, ranging from acute psychiatric hospitals to community residential facilities. These facilities, in turn, serve clients with different needs: some who have high-acuity, short-term needs and others who have chronic, longer-term needs and may return multiple times for care. California, much like many parts of the United States, is confronting a shortage of psychiatric beds. In this article, the authors estimated California's psychiatric bed capacity, need, and shortages for adults at each of three levels of care: acute, subacute, and community residential care. They used multiple methods for assessing bed capacity and need in order to overcome limitations to any single method of estimating the potential psychiatric bed shortfall. The authors identified statewide shortfalls in beds at all levels of inpatient and residential care. They also documented regional differences in the shortfall and identified special populations that contributed to bottlenecks in the continuum of inpatient and residential care in the state.

RESUMEN

Behavioral health (BH) problems are common in the military and can adversely affect force readiness. Research suggests that primary care-behavioral health (PCBH) integration can improve BH outcomes by making high-quality BH care available in more accessible settings. However, sustaining high-quality implementation of PCBH is challenging. The authors conducted a process evaluation of the PCBH program in the military health system to understand why the program is working as it is and provide recommendations for quality improvement. They conducted semistructured interviews, rigorously coded the qualitative data to identify causal links, and created and validated causal loop diagrams that provide a visualization of how the system is working. Findings fall into four key areas: staffing and capabilities, valued tasks, program stewardship, and fostering program awareness and support. Overall, the authors found that the PCBH program is highly valued by primary care staff. However, the PCBH care model is inconsistently adhered to, owing to a combination of staff preferences, local pressures, and lack of knowledge of PCBH staff roles. Recommendations are offered to improve program implementation.

RESUMEN

Identifying predictors of functional recovery in bipolar disorder is critical to treatment efforts to help patients re-establish premorbid levels of role adjustment following an acute manic episode. The current study examined the role of stressful life events as potential obstacles to recovery of functioning in various roles. 65 patients with bipolar I disorder participated in a longitudinal study of functional recovery following clinical recovery from a manic episode. Stressful life events were assessed as predictors of concurrent vs. delayed recovery of role functioning in 4 domains (friends, family, home duties, work/school). Despite clinical recovery, a subset of patients experienced delayed functional recovery in various role domains. Moreover, delayed functional recovery was significantly associated with presence of one or more stressors in the prior 3 months, even after controlling for mood symptoms. Presence of a stressor predicted longer time to functional recovery in life domains, up to 112 days in work/school. Interventions that provide monitoring, support, and problem-solving may be needed to help prevent or mitigate the effects of stress on functional recovery.

RESUMEN

Although amygdala and frontal lobe functional abnormalities have been reported in patients with mood disorders, the literature regarding major depressive disorder (MDD) is inconsistent. Likely confounds include heterogeneity of patient samples, medication status, and analytic approach. This study evaluated the amygdala and frontal lobe activation in unmedicated MDD patients. Fifteen MDD patients and 15 matched healthy controls were scanned using fMRI during the performance of an emotional face task known to robustly activate the amygdala and prefrontal cortex (PFC). Whole-brain and region of interest analyses were performed, and correlations between clinical features and activation were examined. Significant amygdala and lateral PFC activation were seen within patient and control groups. In a between-group comparison, patients showed significantly reduced activation in the insula, temporal and occipital cortices. In MDD, the presence of anxiety symptoms was associated with decreased orbitofrontal activation. We found robust activation in both the MDD and control groups in fronto-limbic regions with no significant between-group differences using either analytic approach. The current study replicates previous research on unmedicated subjects showing no significant differences in amygdala function in depressed vs. control subjects with respect to simple tasks involving emotion observation.

RESUMEN

The present study examines a transactional, interpersonal model of depression in which stress generation (Hammen, 1991) in romantic relationships mediates the association between aspects of interpersonal style (i.e., attachment, dependency, and reassurance seeking) and depressive symptoms. It also examines an alternative, diathesis-stress model in which interpersonal style interacts with romantic stressors in predicting depressive symptoms. These models were tested in a sample of college women, both prospectively over a four-week period, as well as on a day-today basis using a daily diary methodology. Overall, there was strong evidence for a transactional, mediation model in which interpersonal style predicted romantic conflict stress, and in turn depressive symptoms. The alternative diathesis-stress model of depression was not supported. These results are interpreted in relation to previous research, and key limitations that should be addressed by future research are discussed.

RESUMEN

BACKGROUND: This study explored the relatively neglected role of chronic stress in major depression, examining the independent contributions of co-occurring chronic and acute stress to depression, whether chronic stress predicts acute life events, and whether the two types of stress interact such that greater chronic stress confers greater sensitivity-or resistance-to the depressive effects of acute stressors. METHODS: From a sample of 816 community women, those who had a major depression onset in the past 9 months and those without major depressive episodes (MDE) onset and with no history of current or recent dysthymic disorder were compared on interview-based measures of antecedent acute and chronic stress. Chronic stress interviews rated objective stress in multiple everyday role domains, and acute stress was evaluated with contextual threat interviews. RESULTS: MDE onset was significantly associated with both chronic and acute stress; chronic stress was also associated with the occurrence of acute events, and there was a trend suggesting that increased acute stress is more strongly associated with depression in those with high versus low chronic stress. CONCLUSIONS: Results suggest the importance of including assessment of chronic stress in fully understanding the extent and mechanisms of stress-depression relationships.
