ABSTRACT

There is increasing interest in the integration of patient-reported outcomes (PROs) into health care research and clinical practice for the benefit of patients with end-stage kidney disease receiving hemodialysis. In a research setting, PROs can be used as a patient-centered primary or secondary outcome in clinical studies. In routine care, PRO data may be used to support service delivery through benchmarking and audit or inform and enhance the care of the individual patient by improving patient-clinician communication. Despite evidence demonstrating the potential benefits of PROs and prioritization of these outcomes by patients, their use in kidney disease remains limited. Although there are significant methodological and operational challenges for the widespread integration of PROs, there is now consensus that this area should be at the forefront of clinical research and implementation science. We discuss the current use of PROs for patients with end-stage kidney disease receiving hemodialysis and identify a roadmap for increasing the evidence base and introducing PROs into mainstream clinical practice.

ABSTRACT

RATIONALE & OBJECTIVE: Chronic kidney disease (CKD) can substantially affect patients' health-related quality of life. Electronic patient-reported outcome measures (ePROMs) may capture symptoms and health-related quality of life and assist in the management of CKD. This study explored patient and clinician views on the use of a renal ePROM system. STUDY DESIGN: Qualitative study. SETTING & PARTICIPANTS: 12 patients with stage 4 or 5 CKD (non-dialysis dependent); 22 clinicians (6 CKD community nurses, 1 clinical psychologist, 10 nephrologists, 3 specialist registrars, and 2 renal surgeons) in the United Kingdom. ANALYTICAL APPROACH: Semi-structured interviews and focus group discussion during which patients received paper versions of the Kidney Disease Quality of Life-36 and the Integrated Patient Outcome Scale-Renal to exemplify the type of content that could be included in an ePROM. Thematic analysis of interview transcripts. RESULTS: 4 themes were identified: (1) general opinions of PROMs, (2) potential benefits and applications of an ePROM system, (3) practical considerations for the implementation of ePROMs, and (4) concerns, barriers, and facilitators. Patients were willing to complete ePROMs on a regular basis as part of their care despite clinician concerns about patient burden. Patients assessed the questionnaires favorably. Clinicians suggested that the extent of adoption of renal ePROM systems in routine clinical settings should be based on evidence of significant impact on patient outcomes. Clinicians were concerned that an ePROM system may raise patient expectations to unrealistic levels and expose clinicians to the risk for litigation. Patients and clinicians identified potential benefits and highlighted issues and concerns that need to be addressed to ensure the successful implementation of the renal ePROM system. LIMITATIONS: Transferability of the findings may be limited because only English-speaking participants were recruited to the study. CONCLUSIONS: A renal ePROM system may play a supportive role in the routine clinical management of patients with advanced CKD if the concerns of clinicians and patients can be sufficiently addressed.

ABSTRACT

BACKGROUND: Chronic kidney disease (CKD) is associated with increased left ventricular (LV) mass and arterial stiffness. In a previous trial, spironolactone improved these end points compared with placebo in subjects with early-stage CKD, but it is not known whether these effects were specific to the drug or secondary to blood pressure lowering. AIM: The aim was to investigate the hypothesis that spironolactone is superior to chlorthalidone in the reduction of LV mass while exerting similar effects on blood pressure. DESIGN: This is a multicenter, prospective, randomized, open-label, blinded end point clinical trial initially designed to compare the effects of 40weeks of treatment with spironolactone 25mg once daily to chlorthalidone 25mg once daily on the co-primary end points of change in pulse wave velocity and change in LV mass in 350 patients with stages 2 and 3 CKD on established treatment with an angiotensin-converting enzyme inhibitor or an angiotensin receptor blocker. Because of slow recruitment rates, it became apparent that it would not be possible to recruit this sample size within the funded time period. The study design was therefore changed to one with a single primary end point of LV mass requiring 150 patients. Recruitment was completed on 31 December 2016, at which time 154 patients had been recruited. Investigations included cardiac magnetic resonance imaging, applanation tonometry, 24-hour ambulatory blood pressure monitoring, and laboratory tests. Subjects are assessed before and after 40weeks of randomly allocated drug therapy and at 46weeks after discontinuation of the study drug.

ABSTRACT

The goal of this review is to discuss the state of the science in elder abuse prevention. Findings from evidence-based programs to reduce elder abuse are discussed, drawing from findings and insights from evidence-based programs for child maltreatment and domestic/intimate partner violence. A conceptual measurement model for the study of elder abuse is presented and linked to possible measures of risk factors and outcomes. Advances in neuroscience in child maltreatment and novel measurement strategies for outcome assessment are presented.

ABSTRACT

Based on ethnographic fieldwork and interviews collected with meditation teachers and students in the United States, this article will argue that active training in meditation-based practices occasions the opportunity for people with traumatic stress to develop a stronger mind-body connection through heightened somatic awareness and a focus on the present moment that they find to be therapeutic. Three important themes related to healing through meditation for trauma emerged from the data and centered around the ways our interlocutors attempted to realign their sense of self, mind and body, after a traumatic experience. The themes helped explain why US women perceive meditation as therapeutic for trauma, namely that the practice of meditation enables one to focus on the lived present rather than traumatic memories, to accept pain and "open" one's heart, and to make use of silence instead of speech as a healing modality. As meditation practices increasingly enter global popular culture, promoted for postulated health benefits, the driving question of this research--how meditation may perpetuate human resilience for women who have experienced trauma based on their own perspectives of meditation practices--is a critical addition to the literature.

ABSTRACT

BACKGROUND: Accurate blood pressure monitoring is critical for the management of chronic kidney disease, but changes in management in secondary care clinics may be based on a single blood pressure reading, with a subsequent lack of accuracy. The aim of this study was to evaluate a fully automated sphygmomanometer for optimising the accuracy of blood pressure measurements in the setting of secondary care renal clinics. METHODS: Patients had routine blood pressure measurements with a calibrated DINAMAP PRO400 monitor in a clinical assessment room. Patients then underwent repeat assessment with a DINAMAP PRO400 monitor and BpTRU device and subsequent 24 hour ambulatory blood pressure monitoring (ABPM). RESULTS: The BpTRU systolic (± SD) reading (117.3 ± 14.1 mmHg) was significantly lower than the routine clinic mean systolic blood pressure (143.8 ± 15.5 mmHg; P < 0.001) and the repeat blood pressure taken with a DINAMAP PRO400 monitor in a quiet room (129.9 ± 19.9 mmHg; P < 0.001). The routine clinic mean diastolic (82.4 ± 11.2 mmHg) was significantly higher than the BpTRU reading (78.4 ± 10.0 mmHg; P < 0.001). Clinic BpTRU measurements were not significantly different to the daytime mean or overall mean of 24 hour ABPM. CONCLUSIONS: In patients with CKD, routine clinic blood pressure measurements were significantly higher than measurements using a BpTRU machine in a quiet room, but there was no significant difference in this setting between BpTRU readings and 24 hour ABPM. Adjusting clinic protocols to utilise the most accurate blood pressure technique available is a simple manoeuvre that could deliver major improvements in clinical practice.

ABSTRACT

BACKGROUND: Chronic kidney disease (CKD) affects up to 16% of the adult population and is associated with significant morbidity and mortality. People at highest risk from progressive CKD are defined by a sustained decline in estimated glomerular filtration rate (eGFR) and/or the presence of significant albuminuria/proteinuria and/or more advanced CKD. Accurate mapping of the bio-clinical determinants of this group will enable improved risk stratification and direct the development of better targeted management for people with CKD. METHODS/DESIGN: The Renal Impairment In Secondary Care study is a prospective, observational cohort study, patients with CKD 4 and 5 or CKD 3 and either accelerated progression and/or proteinuria who are managed in secondary care are eligible to participate. Participants undergo a detailed bio-clinical assessment that includes measures of vascular health, periodontal health, quality of life and socio-economic status, clinical assessment and collection of samples for biomarker analysis. The assessments take place at baseline, and at six, 18, 36, 60 and 120 months; the outcomes of interest include cardiovascular events, progression to end stage kidney disease and death. DISCUSSION: The determinants of progression of chronic kidney disease are not fully understood though there are a number of proposed risk factors for progression (both traditional and novel). This study will provide a detailed bio-clinical phenotype of patients with high-risk chronic kidney disease (high risk of both progression and cardiovascular events) and will repeatedly assess them over a prolonged follow up period. Recruitment commenced in Autumn 2010 and will provide many outputs that will add to the evidence base for progressive chronic kidney disease.

ABSTRACT

In this article, we consider the use of Mindfulness-Based Stress Reduction (MBSR) (Kabat-Zinn, 1991) as a community-based intervention to reduce health disparities for low-income, predominantly African American women with a history of intimate partner violence (IPV) and posttraumatic stress disorder (PTSD). This article presents our rationale for using MBSR as an intervention with this population, the details of its implementation, and a discussion of the feasibility and acceptability of the intervention based on participants' feedback and our observations. We conclude that the use of MBSR programs for low-income, predominantly African American women with PTSD and a history of IPV is both feasible (of initial interest to and completed by most participants) and acceptable (congruent with and relevant to their needs). Replication with larger samples and examination of mechanisms is warranted by these findings.

ABSTRACT

OBJECTIVE: This study examined the effectiveness of an intensive, experiential intervention, the Holistic Healing Arts Retreat, for improving posttraumatic symptoms (primary) and comorbid depression and perceived stress (secondary). METHOD: The sample consisted of women exposed to childhood physical or sexual abuse, sexual assault, or domestic violence in a two-arm randomized control trial comparing retreat now (n = 49) versus retreat later (n = 60) conditions. We also examined the retreat's effectiveness for improving potential transdiagnostic mechanisms (self-compassion, experiential avoidance, nonreactivity, negative self-affect) common to emotional disorders. Assessments were conducted at baseline and 1, 4, and 7 months following the retreat. RESULTS: Linear mixed-effects models, adjusted for age and level of trauma exposure, showed statistically significant improvements in posttraumatic symptoms (d = .65, .55, .70), depression (d = .42, .39, .41), and perceived stress (d = .47, .50, .57) at 1, 4, and 7 months, respectively, with the exception of posttraumatic symptoms at 4 months, which showed a trend (p ≤ .06). Linear mixed-effects models, adjusted for age, also showed statistically significant improvements in self-compassion (d = .78, .71, .62) and experiential avoidance (d = .34, .34, .51) at 1-, 4-, and 7-month time points, respectively; nonreactivity (affect regulation) at 1 and 7 months (d = .58 and .44, respectively) and nonjudging (negative self-affect) at 4 and 7 months (d = .63 and .71, respectively). CONCLUSIONS: These results suggest this intense, experiential, holistic, retreat-based intervention is effective and efficient among trauma-exposed women for lasting change in trauma-related outcomes, as well as transdiagnostic mechanisms.

ABSTRACT

Background: Existing literature points to higher rates of trauma disorders for forced migrants than general or immigrant populations. The process of identification and screening for trauma in this population however is not straightforward and is actually controversial in some circles. Furthermore there are no definitive guidelines for mental health and social service providers on the "when" "who", "what" "why", "where", and "how" of trauma screening. Objectives: Importantly, few studies have included insights into the screening process from service providers and forced migrants themselves through participatory research methods. This study investigates effective screening processes for trauma and examines benefits and pitfalls of current practices from the perspectives of both migrants themselves as well as health service providers that serve them. Design: We used a qualitative approach to identify and analyze key themes from focus group interviews with key informants (service providers and trauma experts providing social and medical services in the community) and forced migrants (from Cameroon, Ethiopia, Honduras, and Tanzania). Results: Our results comprise forced migrant definitions of and approaches to coping with trauma, reservations about engaging with providers, positive experiences with and impacts of screening, limitations and negative aspects of screening, helpful screening practices, and effective tools and questions for screening. Conclusions: Drawing on these themes, we offer recommendations that may help inform future screening approaches and trauma-informed service provision. The study ultimately helps those in the field to reflect on current trauma screening practices for forced migrants and consider how new insights derived from rich discussions with migrants and their service providers may alter existing screening processes- which few.

ABSTRACT

Importance: Anxiety disorders are common, highly distressing, and impairing conditions. Effective treatments exist, but many patients do not access or respond to them. Mindfulness-based interventions, such as mindfulness-based stress reduction (MBSR) are popular and can decrease anxiety, but it is unknown how they compare to standard first-line treatments. Objective: To determine whether MBSR is noninferior to escitalopram, a commonly used first-line psychopharmacological treatment for anxiety disorders. Design, Setting, and Participants: This randomized clinical trial (Treatments for Anxiety: Meditation and Escitalopram [TAME]) included a noninferiority design with a prespecified noninferiority margin. Patients were recruited between June 2018 and February 2020. The outcome assessments were performed by blinded clinical interviewer at baseline, week 8 end point, and follow-up visits at 12 and 24 weeks. Of 430 individuals assessed for inclusion, 276 adults with a diagnosed anxiety disorder from 3 urban academic medical centers in the US were recruited for the trial, and 208 completed the trial. Interventions: Participants were 1:1 randomized to 8 weeks of the weekly MBSR course or the antidepressant escitalopram, flexibly dosed from 10 to 20 mg. Main Outcomes and Measures: The primary outcome measure was anxiety levels as assessed with the Clinical Global Impression of Severity scale (CGI-S), with a predetermined noninferiority margin of -0.495 points. Results: The primary noninferiority sample consisted of 208 patients (102 in MBSR and 106 in escitalopram), with a mean (SD) age of 33 (13) years; 156 participants (75%) were female; 32 participants (15%) were African American, 41 (20%) were Asian, 18 (9%) were Hispanic/Latino, 122 (59%) were White, and 13 (6%) were of another race or ethnicity (including Native American or Alaska Native, more than one race, or other, consolidated owing to low numbers). Baseline mean (SD) CGI-S score was 4.44 (0.79) for the MBSR group and 4.51 (0.78) for the escitalopram group in the per-protocol sample and 4.49 (0.77) vs 4.54 (0.83), respectively, in the randomized sample. At end point, the mean (SD) CGI-S score was reduced by 1.35 (1.06) for MBSR and 1.43 (1.17) for escitalopram. The difference between groups was -0.07 (0.16; 95% CI, -0.38 to 0.23; P = .65), where the lower bound of the interval fell within the predefined noninferiority margin of -0.495, indicating noninferiority of MBSR compared with escitalopram. Secondary intent-to-treat analyses using imputed data also showed the noninferiority of MBSR compared with escitalopram based on the improvement in CGI-S score. Of patients who started treatment, 10 (8%) dropped out of the escitalopram group and none from the MBSR group due to adverse events. At least 1 study-related adverse event occurred for 110 participants randomized to escitalopram (78.6%) and 21 participants randomized to MBSR (15.4%). Conclusions and Relevance: The results from this randomized clinical trial comparing a standardized evidence-based mindfulness-based intervention with pharmacotherapy for the treatment of anxiety disorders found that MBSR was noninferior to escitalopram.

ABSTRACT

Background: Many Gulf War (GW) Veterans report chronic symptoms including pain, fatigue, and cognitive impairment, commonly defined as Gulf War Illness (GWI). Complementary and integrative health (CIH) therapies may potentially improve multiple symptoms of GWI. Objective: To examine the effectiveness of combining 2 commonly available CIH therapies, mindfulness meditation and auricular acupuncture, in improving health-related functioning and multiple symptom domains of GWI (e.g., pain, fatigue). Methods: This study was a randomized controlled trial in which Veterans with GWI were randomly assigned to either the intervention group (n = 75), wherein they received 2 distinct CIH therapies - mindfulness meditation and auricular acupuncture, or the active control group, wherein they received a GW Health Education (GWHE) program (n = 74), each lasting 8 weeks. Self-report health measures were assessed at baseline, endpoint, and 3 month follow-up. Results: In the intention-to-treat analyses, there were significant between-group differences for mental-health related functioning, fatigue, depression symptoms, and Kansas total severity scores for symptoms in which the CIH group had improved scores for these outcomes at endpoint compared to the GWHE group (all P ≤ .05). The CIH group also had significant reductions in pain interference at endpoint and follow-up compared to baseline (estimated marginal mean difference: -2.52 and -2.22, respectively; all P = .01), whereas no significant changes were observed in the GWHE group. For pain characteristics, the GWHE group had a worsening of pain at endpoint compared to baseline (estimated marginal mean difference: +2.83; P = .01), while no change was observed in the CIH group. Conclusion: Findings suggest a possible beneficial effect of combining 2 CIH therapies, mindfulness meditation and auricular acupuncture, in reducing overall symptom severity and individual symptom domains of fatigue, musculoskeletal, and mood/cognition in Veterans with GWI. Trial Registration: Clinical Trials identifier NCT02180243.

ABSTRACT

Most people are much less generous toward strangers than close others, a bias termed social discounting. But people who engage in extraordinary real-world altruism, like altruistic kidney donors, show dramatically reduced social discounting. Why they do so is unclear. Some prior research suggests reduced social discounting requires effortfully overcoming selfishness via recruitment of the temporoparietal junction. Alternatively, reduced social discounting may reflect genuinely valuing strangers' welfare more due to how the subjective value of their outcomes is encoded in regions such as rostral anterior cingulate cortex (ACC) and amygdala. We tested both hypotheses in this pre-registered study. We also tested the hypothesis that a loving-kindness meditation (LKM) training intervention would cause typical adults' neural and behavioral patterns to resemble altruists. Altruists and matched controls (N = 77) completed a social discounting task during functional magnetic resonance imaging; 25 controls were randomized to complete LKM training. Neither behavioral nor imaging analyses supported the hypothesis that altruists' reduced social discounting reflects effortfully overcoming selfishness. Instead, group differences emerged in social value encoding regions, including rostral ACC and amygdala. Activation in these regions corresponded to the subjective valuation of others' welfare predicted by the social discounting model. LKM training did not result in more generous behavioral or neural patterns, but only greater perceived difficulty during social discounting. Our results indicate extraordinary altruists' generosity results from the way regions involved in social decision-making encode the subjective value of others' welfare. Interventions aimed at promoting generosity may thus succeed to the degree they can increase the subjective valuation of others' welfare.

ABSTRACT

OBJECTIVES: The use of routine remote follow-up of patients with chronic kidney disease (CKD) is increasing exponentially. It has been suggested that online electronic patient-reported outcome measures (ePROMs) could be used in parallel, to facilitate real-time symptom monitoring aimed at improving outcomes. We tested the feasibility of this approach in a pilot trial of ePROM symptom monitoring versus usual care in patients with advanced CKD not on dialysis. DESIGN: A 12-month, parallel, pilot randomised controlled trial (RCT) and qualitative substudy. SETTING AND PARTICIPANTS: Queen Elizabeth Hospital Birmingham, UK. Adult patients with advanced CKD (estimated glomerular filtration rate ≥6 and ≤15 mL/min/1.73 m2, or a projected risk of progression to kidney failure within 2 years ≥20%). INTERVENTION: Monthly online ePROM symptom reporting, including automated feedback of tailored self-management advice and triggered clinical notifications in the advent of severe symptoms. Real-time ePROM data were made available to the clinical team via the electronic medical record. OUTCOMES: Feasibility (recruitment and retention rates, and acceptability/adherence to the ePROM intervention). Health-related quality of life, clinical data (eg, measures of kidney function, kidney failure, hospitalisation, death) and healthcare utilisation. RESULTS: 52 patients were randomised (31% of approached). Case report form returns were high (99.5%), as was retention (96%). Overall, 73% of expected ePROM questionnaires were received. Intervention adherence was high beyond 90 days (74%) and 180 days (65%); but dropped beyond 270 days (46%). Qualitative interviews supported proof of concept and intervention acceptability, but highlighted necessary changes aimed at enhancing overall functionality/scalability of the ePROM system. LIMITATIONS: Small sample size. CONCLUSIONS: This pilot trial demonstrates that patients are willing to be randomised to a trial assessing ePROM symptom monitoring. The intervention was considered acceptable; though measures to improve longer-term engagement are needed. A full-scale RCT is considered feasible. TRIAL REGISTRATION NUMBER: ISRCTN12669006 and the UK NIHR Portfolio (CPMS ID: 36497).

ABSTRACT

This study examined the role of several hypothesized predictors of the impact of a potentially traumatic event, the terrorist attacks of September 11, 2001 (9/11), on a sample of women experiencing intimate partner violence (IPV) and related posttraumatic stress symptoms (PTSS). We found that IPV-related PTSS mediated the relationship between IPV and 9/11-related PTSS, confirming the hypothesis that severity of symptoms related to prior trauma plays a role in the development and severity of PTSS related to subsequent potentially traumatic events. Media exposure and threat appraisal were significantly positively associated with 9/11-related PTSS, whereas social support was significantly negatively associated with 9/11-related PTSS, with none of these variables serving as moderators of the relationship between IPV-related and 9/11-related PTSS. Our results suggest that trauma-related psychiatric history is an important factor in the development of PTSS subsequent to an additional potentially traumatic event, even after adjusting for relevant variables occurring at the time of that event.

ABSTRACT

BACKGROUND: Screening for suicidal ideation in high-risk groups such as U.S. veterans is crucial for early detection and suicide prevention. Currently, screening is based on clinical interviews or self-report measures. Both approaches rely on subjects to disclose their suicidal thoughts. Innovative approaches are necessary to develop objective and clinically applicable assessments. Speech has been investigated as an objective marker to understand various mental states including suicidal ideation. In this work, we developed a machine learning and natural language processing classifier based on speech markers to screen for suicidal ideation in US veterans. METHODOLOGY: Veterans submitted 588 narrative audio recordings via a mobile app in a real-life setting. In addition, participants completed self-report psychiatric scales and questionnaires. Recordings were analyzed to extract voice characteristics including prosodic, phonation, and glottal. The audios were also transcribed to extract textual features for linguistic analysis. We evaluated the acoustic and linguistic features using both statistical significance and ensemble feature selection. We also examined the performance of different machine learning algorithms on multiple combinations of features to classify suicidal and non-suicidal audios. RESULTS: A combined set of 15 acoustic and linguistic features of speech were identified by the ensemble feature selection. Random Forest classifier, using the selected set of features, correctly identified suicidal ideation in veterans with 86% sensitivity, 70% specificity, and an area under the receiver operating characteristic curve (AUC) of 80%. CONCLUSIONS: Speech analysis of audios collected from veterans in everyday life settings using smartphones offers a promising approach for suicidal ideation detection. A machine learning classifier may eventually help clinicians identify and monitor high-risk veterans.

ABSTRACT

OBJECTIVES: Patients undergoing haemodialysis report elevated symptoms and reduced health-related quality of life, and often prioritise improvements in psychosocial well-being over long-term survival. Systematic collection and use of patient-reported outcomes (PROs) may help support tailored healthcare and improve outcomes. This study investigates the methodological basis for routine PRO assessment, particularly using electronic formats (ePROs), to maximise the potential of PRO use, through exploration of the experiences, views and perceptions of patients and healthcare professionals (HCPs) on implementation and use of PROs in haemodialysis settings. STUDY DESIGN: Qualitative study. SETTING AND PARTICIPANTS: Semistructured interviews with 22 patients undergoing haemodialysis, and 17 HCPs in the UK. ANALYTICAL APPROACH: Transcripts were analysed deductively using the Consolidated Framework for Implementation Research (CFIR) and inductively using thematic analysis. RESULTS: For effective implementation, the potential value of PROs needs to be demonstrated empirically to stakeholders. Any intervention must remain flexible enough for individual and aggregate use, measuring outcomes that matter to patients and clinicians, while maintaining operational simplicity. Any implementation must sit within a wider framework of education and support for both patients and clinicians who demonstrate varying previous experience of using PROs and often confuse related concepts. Implementation plans must recognise the multidimensionality of end-stage kidney disease and treatment by haemodialysis, while acknowledging the associated challenges of delivering care in a highly specialised environment. To support implementation, careful consideration needs to be given to barriers and facilitators including effective leadership, the role of champions, effective launch and ongoing evaluation. CONCLUSIONS: Using the CFIR to explore the experiences, views and perceptions of key stakeholders, this study identified key factors at organisational and individual levels which could assist effective implementation of ePROs in haemodialysis settings. Further research will be required to evaluate subsequent ePRO interventions to demonstrate the impact and benefit to the dialysis community.

ABSTRACT

The goal of HIV treatment is viral suppression as it is linked with improved health outcomes and decreased risk of viral transmission. We assessed the sociodemographic, behavioral, and patient-provider interaction associations with viral suppression with an administered survey to HIV-seropositive women in the metropolitan Washington, DC, site of the Women's Interagency HIV Study (WIHS) between 2017 and 2018. Logistic and mixed models were used to explore related factors between HIV viral suppression groups and HIV treatment self-efficacy, respectively. Higher HIV treatment self-efficacy and disclosure concerns were positively associated with viral suppression, while illicit drug use had a negative association. In mixed models, more health care provider trust was associated with higher HIV treatment self-efficacy, while depressive symptoms were associated with lower HIV treatment self-efficacy. Depression, illicit substance use, and HIV treatment self-efficacy are potentially modifiable factors that can influence viral suppression. Implementation studies are needed to determine whether interventions to manage depression or self-efficacy and improve trust in health care providers will influence treatment outcomes.

ABSTRACT

What do we know about resilience in crime victimization? In this article, the authors discuss resilience defined as protective factors (e.g., personality characteristics, biological characteristics, social and cultural factors, and community characteristics); as a process of adaptation (e.g., self-enhancement, positive cognitive appraisals, coping styles, and spirituality), including an iterative perspective on resilience as a cascade of protective processes; and as positive outcomes (e.g., lack of symptoms) following exposure to adverse events. Within each of these definitional frameworks, they consider general conceptual issues pertaining to resilience and then the small body of research that has focused specifically on resilience and some type of crime victimization. Research and clinical implications are discussed.
