Determination of optimal vibration dose to treat Parkinson's disease gait symptoms: A clinical trial.

Introduction: Most people with Parkinson's disease (PD) will experience gait problems. Previous studies demonstrated improved gait and balance after vibration stimulation was applied to the feet of PD patients. However, not all study participants showed improvement, perhaps due to sub-optimal vibration stimulus. Thus far, the optimal frequency and amplitude of vibration for mitigating gait dysfunction in PD have yet to be systematically explored. This study aimed to deliver vibration to the feet of 26 people with PD gait disturbances. We hypothesized that a global frequency, amplitude, and minimum duration of vibration therapy are required to improve PD gait issues. Methods: This was a phase Ib trial to identify optimal vibration parameters. Thirteen participants were recruited at Hoehn & Yahr (H&Y) stage II and 13 participants at stage III. Each group was randomly assigned to different frequency and amplitude settings prescribed by the central composite design methodology. Each participant received vibration for 18 min per walking session, for eight sessions spread over one week. Results: Results showed an optimal response to treatment for frequency (Hz) and amplitude (mm) of vibration based on the Functional Ambulation Performance score for stages II and III. In the H&Y stage II group, stabilization of outcomes occurred after the 4th treatment. This stabilization was not seen in stage III participants. Conclusions: A global frequency and vibration amplitude have been identified for treating PD gait disorders. Patients with more advanced disease may require a longer duration of therapy.

Family history of substance problems among African Americans: Associations with drug use, drug use disorder, and prescription drug misuse.

A family history of substance problems is a well-known risk factor for substance use and use disorders; however, much of this research has been conducted in studies with predominantly White subjects. The aim of this study was to examine the associations between family history density of substance problems and drug use, risk for drug use disorder, and prescription drug misuse in a sample of African American adults. Results indicate that family history density of substance problems increased the risk for all drug outcomes in the full sample. However, when subgroup analyses by gender were conducted, family history was not a risk factor among men for prescription drug misuse.

Exploration of the psychometric properties of the EPDS-US, a validation study.

INTRODUCTION: The purpose of this study was to explore the reliability and construct validity of the EPDS-US. METHODS: To enhance the perinatal mental health screen, we adapted the Edinburgh Postnatal Depression Screen (EPDS) for application in the United States, and evaluated reliability and construct validity of the EPDS-US in a sample of 100 postpartum individuals. We explored reliability by estimating internal consistency of the scale and evaluating concurrent validity with correlations to the Patient Health Questionnaire (PHQ-9) and the Generalized Anxiety Disorder Assessment (GAD-7); and construct validity using factor analysis and discriminant validity with correlations to the Perceived Stress Scale (PSS). RESULTS: We present both a one-factor (Cronbach's alpha of 0.83) and two-factor model consisting of depressive (Cronbach's alpha 0.76) and anxiety symptoms (Cronbach's alpha 0.78) of the EPDS-US. Related to discriminant validity, the EPDS-US and PSS exhibited a moderate correlation of 0.71. For measures of concurrent validity, correlations with the PHQ-9 and GAD-7 were moderate; 0.63 and 0.68, respectively. CONCLUSION: The EPDS-US was adapted to enhance the perinatal mental health screening experience for populations in the US while maintaining the reliability and validity of the original Edinburgh Postnatal Depression Scale. These findings contribute to the evidence of reliability and validity of the EPDS-US in perinatal populations in the United States; presenting initial evidence supporting construct validity and concurrent validity of this newly adapted 10-item scale.

Development and psychometric evaluation of the Symptom Self-Management Behaviors Tool for adolescents/young adults with cancer.

OBJECTIVES: Adolescents and Young Adults (AYAs) with cancer experience symptoms related to disease and treatment. To manage these symptoms, they need to develop self-management behaviors, yet no tool exists to assess these behaviors. The Symptom Self-Management Behaviors Tool (SSMBT) was developed to meet this need. METHODS: The study consisted of 2 phases. Phase 1 evaluated content validity, and Phase 2 evaluated reliability and validity. The SSMBT initially contained 14 items with 2 dimensions: (1) behaviors used to Manage Symptoms and (2) behaviors used to communicate with providers regarding symptoms. Four oncology professionals and 5 AYAs with cancer assessed the content validity. Evaluation of reliability and validity involved 61 AYAs with cancer. Reliability was evaluated using Cronbach's alpha. Construct validity was assessed with factor analysis. Discriminant validity was assessed using associations with symptom severity and distress. RESULTS: Content validity evaluation supported the importance of the items. Factor analysis supported a two-factor structure: Manage Symptoms (8 items) and Communicate with Healthcare Providers (4 items) subscales. Internal consistency reliability for the total SSMBT was acceptable with Cronbach's alpha = 0.74. Cronbach's alpha value for the Manage Symptoms subscale was α = 0.69 and for the Communicate with Healthcare Providers subscale was α = 0.78. The SSMBT total and the Manage Symptoms subscale scores were moderately correlated with symptom severity (r = 0.35, p = 0.014; r = 0.44, p = 0.002, respectively), partially supporting discriminant validity. SIGNIFICANCE OF RESULTS: Systematic assessment of behaviors AYAs use is critical for clinical practice and evaluate interventions to improve self-management. The SSMBT demonstrates initial reliability and validity but requires further evaluation for clinical interpretation and future use.

A mixed-methods exploration of nurse loneliness and burnout during COVID-19.

AIM: This study investigated the phenomenon of nurse loneliness as a potential contributor to burnout. BACKGROUND: Nurse wellbeing is critical for safe and efficient healthcare delivery. However, evidence indicates nurses' wellbeing is at risk. The levels of burnout, the most commonly measured symptom of suboptimal wellbeing, are rising and may relate to a largely unexplored phenomenon: loneliness. METHODS: A mixed-methods approach was used to investigate burnout and loneliness in direct-care nurses in four diverse hospitals in the midwestern and southeastern United States. Burnout and loneliness were measured, prevalence was estimated, and correlation was examined. Interpretive descriptive inquiry and analysis was used to develop a richer understanding of nurse loneliness in the context of burnout. While this study did not explicitly explore the impact of the global pandemic, data was collected in late 2021 and early 2022, during the Delta variant wave. RESULTS: In the study population (n = 117), rates of burnout are high and positively correlate with loneliness. Qualitative interviews (n = 11) revealed that nurses feel unseen, emotionally detached from their work, and dehumanized. However, social connection with peers is protective and nurses still report a strong sense of devotion to the profession and solidarity with peers. CONCLUSIONS: This study offers insight into nurse loneliness, highlighting the importance of social connectedness to improve nurse wellbeing.

Perceptions and Experiences of Hematopoietic Cell Transplantation Patients During the COVID-19 Pandemic.

OBJECTIVES: Since March 2020, the severe acute respiratory syndrome coronavirus-2 pandemic has affected the global community, but poses unique challenges for individuals with cancer. Patients diagnosed with hematologic malignancies undergo aggressive therapies followed by hematopoietic cell transplantation (HCT) as a potential curative treatment. HCT recipients can be immunocompromised for extended periods of time, and even pre-pandemic, transplant patients reported depression and anxiety due to restrictions and infection prevention measures they had to adhere to as part of transplant precautions. This study aimed to understand psychological distress and capture perspectives on coping strategies and access to healthcare in the HCT population during the COVID-19 pandemic. DATA SOURCES: Adult patients who received a transplant or were awaiting transplant and had a scheduled appointment at the transplant clinic were eligible to participate in this cross-sectional study. Participants completed an online survey that included questionnaires, clinical data and demographic information. CONCLUSION: Fifty-four participants completed the survey. HCT participants reported relatively high psychological distress during the initial phase of the COVID-19 pandemic, but indicated use of healthy coping mechanisms to deal with stress. IMPLICATION FOR NURSING PRACTICE: Study data informs healthcare providers that psychological distress and mental health warrants increased attention during periods of heightened stress. Education and resources on healthy, beneficial coping strategies should be provided to support HCT patients. Nurses and advanced nurse practitioners are well poised to interact with HCT patients and provide necessary support or appropriate referral during routine clinical interactions, preparing patients for prolonged effects of the pandemic and similar future events.

Factors Affecting Quality of Life in Patients Receiving Autologous Hematopoietic Stem Cell Transplantation.

BACKGROUND: Hematopoietic stem cell transplant (HSCT) is a potentially curative treatment for hematologic malignancies, with 22 000 HSCTs performed annually in the United States. However, decreased quality of life (QoL) is a frequent and concerning state reported by HSCT recipients. OBJECTIVES: We sought to determine if measurements of frailty and cognitive impairment were associated with fatigue and QoL in adult HSCT recipients after autologous HSCT. METHODS: Using a longitudinal study design, 32 participants 18 years or older receiving autologous HSCT were recruited from a bone marrow transplant clinic. Each participant completed 2 visits: pre-HSCT and post-HSCT. At each visit, participants completed assessment tools to measure frailty, cognitive impairment, fatigue, and QoL (assesses physical, social/family, emotional, functional, and transplant-related well-being). RESULTS: Participants with increased fatigue scores reported decreased QoL pre- and post-HSCT. Participants with increased frailty showed decreased functional well-being before HSCT and showed correlations with decreased physical, social, and transplant-related well-being post-HSCT. As expected, fatigued participants also showed increased frailty post-HSCT. Participants showed significant changes in physical well-being and fatigue between pre-HSCT and post-HSCT visits. CONCLUSION: Data analyses from this pilot study show significant correlations between subsets of QoL with fatigue and frailty in autologous HSCT participants pre- and post-HSCT. IMPLICATIONS FOR PRACTICE: Understanding the impact of frailty on fatigue and QoL in HSCT recipients is critical to assist nurses in initiating educational and behavioral interventions to help mitigate the effects of HSCT.

Symptom Profiles of Adolescents and Young Adults in Active Cancer Treatment by Diagnostic Groups.

BACKGROUND: The symptom experience of adolescents and young adults (AYAs) with cancer can differ based on the cancer and its treatments. A dearth of information exists on how symptoms differ by individual factors such as age and gender. OBJECTIVES: The objectives were to describe symptoms in AYAs across 5 cancer diagnostic groups by the individual factors of age group, sex, race/ethnicity, and time since diagnosis; and then to describe symptoms based on these individual factors within diagnostic groups. METHODS: This was a secondary analysis of baseline data pooled from 2 multisite studies on symptoms in AYAs with acute lymphoblastic leukemia, brain cancer, Hodgkin lymphoma, non-Hodgkin lymphoma, and sarcoma. Symptoms were assessed using the Computerized Symptom Capture Tool. RESULTS: Data from 118 AYAs with cancer, aged 13 to 29 years, were analyzed. Eight of the most commonly reported symptoms were reported in at least 4 diagnostic groups. Across diagnostic groups, symptoms varied little based on individual factors. Within groups, certain symptoms differed in frequency by individual factors. CONCLUSIONS: The lack of major differences in symptom prevalence based on individual factors across diagnostic groups supports a heterogeneous approach to symptom research with AYAs. The study identified individual factors within diagnostic groups worthy of further exploration. IMPLICATIONS FOR PRACTICE: Providers can facilitate discussions with AYAs about symptoms by being aware of common symptoms that may occur in certain cancer diagnostic groups and based on individual factors. The significance of the individual symptom experience should not be underestimated, emphasizing the importance of person-centered symptom assessment.

Facing the Inevitable: Preparing Nurses to Deliver End-of-Life Care.

Health care providers have an ethical obligation to reduce suffering during a patient's end of life (EOL), but few receive formal education on EOL care principles. The objective of this project was to determine the feasibility and potential benefits of an education initiative in which the principles of EOL care were taught to senior-level nursing students and practicing nurses. To assess feasibility, data regarding recruitment rates, retention rates, and implementation issues were collected. Workshop effectiveness was evaluated through use of the End-of-Life Nursing Education Consortium-Knowledge Assessment Test survey, which evaluates knowledge levels regarding EOL care principles. A mixed-effects linear model was used to test for changes from the preworkshop to postworkshop scores. Demographic information and satisfaction data were also collected. Nineteen students and 24 nurses participated (total N = 43). There was a statistically significant time difference (P = .0001), with the postworkshop scores being higher (43.5 ± 0.93) versus the preworkshop scores (41.2 ± 0.93). However, no statistically significant workshop date difference (P = .3146) emerged. Satisfaction data were positive. Retention for the second workshop was negatively affected by COVID-19. The unique needs of patients nearing their EOL are significant. This project describes the implementation and outcomes of an education initiative, focused on EOL care principles, that was both feasible and beneficial.

Happiness in Pregnant African American Women: What Are the Biobehavioral Correlates?

The detrimental effects of prenatal stress on maternal-infant well-being have been well established and highlight increased concern for pregnant African American women. Research supports the notion that positive emotions may have a beneficial impact on the stress process and outcomes. However, the data have been largely restricted to non-African American pregnant women. This study's purpose was to examine potential relationships of both positive (happiness) and negative (stress, anxiety, and depressive symptoms) emotions and pro-inflammatory cytokines (interleukins-1ß, -6, -8, -12, -17, tumor necrosis factor, and interferon-γ) in 72 pregnant African American women for a more complete picture of the stress process in this at-risk population. Results of this exploratory secondary data analysis show strong positive correlations between negative emotions and strong negative correlations between happiness and negative emotions. Interleukin-8 was positively correlated with negative emotions and negatively correlated with happiness. Results show mean ratings of negative emotions were higher than previously reported with more heterogeneous samples, while happiness ratings were in the moderate range. Findings suggest that pregnant African American women may experience higher stress and depressive symptoms than women in more heterogeneous samples. However, moderate levels of happiness might contribute to buffering the stress response.

Body Image, Sexuality, and Sexual Functioning in Women With Gynecologic Cancer: An Integrative Review of the Literature and Implications for Research.

BACKGROUND: Cervical and uterine cancers are common in women. Diagnosis and treatment of these cancers can lead to significant issues with body image, sexuality, and sexual functioning. A comprehensive review can improve understanding of these 3 concepts, in turn enhancing identification and management. OBJECTIVES: To (1) present the qualitative, descriptive, and correlational research literature surrounding body image, sexuality, and sexual functioning in women with uterine and cervical cancer; (2) identify gaps in the literature; and (3) explore the implications of the findings for future research. METHODS: A comprehensive search of the literature was undertaken by searching PubMed, CINAHL, and PsycINFO using predetermined subject headings, keywords, and exploded topics. After a comprehensive evaluation using specific criteria, 121 articles were reviewed. RESULTS: Qualitative studies provided information about women's issues with body image, sexuality, and sexual functioning, whereas quantitative studies focused primarily on sexual functioning. The literature lacks correlational studies examining body image and sexuality. Significant issues regarding communication and quality of life were noted, and few studies were based on clear conceptual models. CONCLUSION: The state of the science gleaned from this review reveals that while much is known about sexual functioning, little is known about body image and sexuality. IMPLICATIONS FOR PRACTICE: Further work is warranted to develop conceptual models and research on body image, sexuality, and sexual functioning as a foundation for interventions to improve quality of life.

Visual Arts in Nursing Education: An Inventive Interprofessional Initiative to Cultivate Metacognitive Awareness in Beginning Nursing Students.

PURPOSE: To test an interdisciplinary art-based educational program for beginning baccalaureate traditional and accelerated nursing students. DESIGN: Longitudinal study (Pretest-Posttest) of nursing students' metacognitive awareness. METHOD: As part of a first-semester foundations nursing course, all students participated in the Art of Nursing program consisting of three 90-minute sessions led by graduate Art Education students in a local fine arts museum. Before and after the program, subcomponents of critical thinking were assessed using the Metacognitive Awareness Inventory (MAI). FINDINGS: A total of 218 students (56 traditional, 162 accelerated) participated. Statistically significant improvement was observed on seven components of the MAI. Although significant increases were observed for Declarative (p < .0001), Planning (p < .0001), and Comprehension Monitoring (p < .0001), the differences pre to post were of different magnitudes between the student groups, characterizing a large change in the traditional versus accelerated group. CONCLUSIONS: Our results suggest that (1) nursing students' metacognitive awareness benefits from the museum-based experience despite demographic and educational differences and (2) overall the accelerated student group has exhibited higher metacognitive awareness at baseline as compared with the traditional student group; however, both groups demonstrate significant growth in this area after experiencing an art-based program.

Telomere lengths in women treated for breast cancer show associations with chemotherapy, pain symptoms, and cognitive domain measures: a longitudinal study.

BACKGROUND: Survival rates for breast cancer (BC) have improved, but quality of life post-diagnosis/treatment can be adversely affected, with survivors reporting a constellation of psychoneurological symptoms (PNS) including stress, anxiety, depression, pain, fatigue, sleep disturbance, and cognitive dysfunction. METHODS: To assess a potential relationship between telomere length (TL) and the development/persistence of PNS, we longitudinally studied 70 women (ages 23-71) with early stage BC (I-IIIA) at 5 time-points: prior to treatment (baseline), the mid-point of their chemotherapy cycle, 6 months, 1 year, and 2 years following the initiation of chemotherapy. Measures quantified included assessments of each of the PNS noted above and TL [using both a multiplex qPCR assay and a chromosome-specific fluorescence in situ hybridization (FISH) assay]. RESULTS: Variables associated with qPCR mean TLs were age (p = 0.004) and race (T/S ratios higher in Blacks than Whites; p = 0.019). Significant differences (mostly decreases) in chromosome-specific TLs were identified for 32 of the 46 chromosomal arms at the mid-chemo time-point (p = 0.004 to 0.049). Unexpectedly, the sequential administration of doxorubicin [Adriamycin], cyclophosphamide [Cytoxan], and docetaxel [Taxotere] (TAC regimen) was consistently associated with higher TLs, when compared to TLs in women receiving a docetaxel [Taxotere], Carboplatin [Paraplatin], and trastuzumab [Herceptin] [TCH] chemotherapy regimen [association was shown with both the qPCR and FISH assays (p = 0.036)]. Of the PNS, pain was significantly negatively associated with TL (higher pain; shorter telomeres) for a subset of chromosomal arms (5q, 8p, 13p, 20p, 22p, Xp, Xq) (p = 0.014-0.047). Chromosomal TLs were also associated with 7 of the 8 cognitive domains evaluated, with the strongest relationship being noted for chromosome 17 and the visual memory domain (shorter telomeres; lower scores). CONCLUSIONS: We showed that race and age were significantly associated with telomere length in women treated for early stage BC and that acquired telomere alterations differed based on the woman's treatment regimen. Our study also demonstrated that pain and cognitive domain measures were significantly related to telomere values in this study cohort. Expanding upon the knowledge gained from this longitudinal study could provide insight about the biological cascade of events that contribute to PNS related to BC and/or its treatment.

Exercise Testing of Adolescents and Young Adults With Sickle Cell Disease: Perceptual Responses and the Gas Exchange Threshold.

For individuals with sickle cell disease (SCD), mild to moderate exercise is advised, but self-regulation of these intensities is difficult. To regulate intensity, one SCD recommendation is to stop exercising at the first perception of fatigue. However, perceived effort and affect (how one feels) are perceptual cues that are commonly used to guide exercise intensity. This study (a) examined perceived effort, affect, and fatigue in relation to metabolic state (gas exchange) in adolescents and young adults (AYAs) with SCD, (b) explored guidelines AYAs use to self-regulate exercise, and (c) compared perceived effort and affect at gas exchange threshold (GET) with healthy counterparts. Twenty-two AYAs with SCD completed an incremental cycle test. Perceived effort, affect, and fatigue were assessed every 2 minutes. A mixed-effects linear model was conducted to model changes in effort, affect, and fatigue across time. Mean scores of effort and affect at GET were compared with published data of healthy counterparts. Participants were queried about self-regulation exercise strategies. Findings indicated that both perceived fatigue and effort at GET was lower than expected. Perceived effort was lower (p < .0001), and perceived affect was significantly higher (p = .0009) than healthy counterparts. Interviews revealed that most participants (95%) do not stop exercising until fatigue is moderate to severe, and many (73%) do not stop until symptoms are severe (chest tightness, blurry vision). Nurses should review guidelines for safe exercise with AYAs with SCD. Exercise training may be beneficial to AYAs with SCD for learning how to interpret bodily responses to exercise to improve self-regulation.

Using a Heuristic App to Improve Symptom Self-Management in Adolescents and Young Adults with Cancer.

PURPOSE: Adolescents and young adults (AYAs) with cancer need self-management strategies to cope with multiple symptoms. Self-efficacy, self-regulation, and negotiated collaboration are key theoretical components of the self-management process and have not been fully explored with AYAs with cancer. This study examined the effects of a heuristic symptom assessment tool on AYAs' self-efficacy for symptom management, AYAs' self-regulation abilities related to their symptoms, and communication with their providers about symptoms. METHODS: AYAs (15-29 years of age) receiving chemotherapy used the Computerized Symptom Capture Assessment Tool (C-SCAT) to illustrate their symptom experience and discuss their symptoms with providers during two clinic visits. Participants completed the PROMIS Self-efficacy for Managing Symptoms Scale, a measure of satisfaction with provider communication, and a short interview about self-regulation and communication behaviors at baseline and after each provider visit. RESULTS: Eighty-five AYAs who used the C-SCAT showed improved self-efficacy for managing symptoms. Qualitative data suggest that the C-SCAT was useful for enhancing a number of AYAs' self-regulation abilities related to symptom management, such as awareness and recall of symptoms, how symptoms were related, and how they planned to talk about their symptoms to providers. AYAs reported C-SCAT facilitated communication with providers about symptoms and symptom management because it was a visual prompt showing priority and related symptoms. CONCLUSIONS: Because AYAs continue to experience multiple distressing symptoms, symptom self-management remains an important area for practice and research. Use of heuristic tools, such as the C-SCAT, may help AYAs more effectively self-manage their symptoms for better health outcomes.

Perceived Stress and Surgical Wound Cytokine Patterns.

This was a pilot study to examine pre- and postoperative stress experienced by women who were undergoing autologous breast reconstruction and how stress might impact wound healing, specifically examining cytokines and other chemical mediators in the wound environment. A nonexperimental descriptive design over time was utilized. Participants were women who were undergoing autologous abdominal breast reconstruction for breast cancer (N = 20). Data were collected preoperatively and at 24, 48, 72, and 96 hr postsurgery. Complications were monitored intraoperatively and up to 30 days postsurgery. Psychological stress was measured with the 10-item Perceived Stress Scale (PSS), the Impact of Events Scale-Revised (IES-R), and a 100-mm Visual Analog Scale (VAS). Cytokines were assayed using the 27-plex kit with a Bio-Plex Plus. Although breast cancer is considered a stressor, in this sample of women, scores of the PSS, IES-R, and VAS showed that in fact these participants experienced low levels of psychological stress. All measured biochemical mediators in serum and wound fluid were detected and trends were identified. IL-1ra, IL-6, IL-8, G-CSF, IP-10, MCP-1, MIP-1ß, RANTES, and VEGF were present in the highest concentrations. Significant changes in levels of cytokines in wound fluid were observed in IL-1ß, IL-2, IL-5, IL-6, IL-8, IL-9, IL-10, IL-17, FGF-basic, G-CSF, MIP-1α, PDGF-bb, MIP-1ß, RANTES, and TNF-α. The remaining cytokine concentrations stayed stable over time. These findings suggest that although these women were not experiencing high levels of stress, meaningful cytokine patterns were detected.

Symptom Management and Psychosocial Needs of Adults With Acute Myeloid Leukemia During Induction Treatment: A Pilot Study.

BACKGROUND: Patients with a new diagnosis of acute myeloid leukemia (AML) are at risk of experiencing a high symptom burden due to the disease and its treatment, which includes a long period of hospitalization. OBJECTIVE: The aim of this pilot work was to describe the multidimensional symptoms and health-related quality of life experienced by patients with a new diagnosis of AML across induction chemotherapy. METHODS: A prospective, longitudinal descriptive study design was implemented to evaluate symptoms and health-related quality of life at the time of enrollment through 6 weeks postdiagnosis and identify who might be most at risk of experiencing high symptom burden. RESULTS: A total of 19 participants were included in this analysis. Moderate to severe levels of distress were present in 25% to 50% of participants, depending on timing in treatment. Females and those with a previous history of a psychological disorder reported higher symptom burden during treatment. CONCLUSIONS: Our findings indicate that adults with AML experience multiple distressing symptoms during the induction treatment. IMPLICATIONS FOR PRACTICE: Timely routine multidimensional assessment of symptoms in individuals undergoing induction chemotherapy treatment for AML is critical as they may be experiencing multiple concurrent symptoms. Additional research to advance symptom assessment and amelioration of distressing symptoms to improve health-related quality of life is needed in this unique population.

Psychometric Evaluation of the Patient-Reported Outcomes Measurement Information System Fatigue-Short Form Across Diverse Populations.

BACKGROUND: The need for reliable, valid tools to measure patient-reported outcomes (PROs) is critical both for research and for evaluating treatment effects in practice. The Patient-Reported Outcomes Measurement Information System Fatigue-Short Form v1.0-Fatigue 7a (PROMIS F-SF) has had limited psychometric evaluation in various populations. OBJECTIVES: The aim of the study is to examine psychometric properties of PROMIS F-SF item responses across various populations. METHODS: Data from five studies with common data elements were used in this secondary analysis. Samples from patients with fibromyalgia, sickle cell disease, cardiometabolic risk, pregnancy, and healthy controls were used. Reliability was estimated using Cronbach's alpha. Dimensionality was evaluated with confirmatory factor analysis. Concurrent validity was evaluated by examining Pearson's correlations between scores from the PROMIS F-SF, the Multidimensional Fatigue Symptom Inventory-Short Form, and the Brief Fatigue Inventory. Discriminant validity was evaluated by examining Pearson's correlations between scores on the PROMIS F-SF and measures of stress and depressive symptoms. Known groups validity was assessed by comparing PROMIS F-SF scores in the clinical samples to healthy controls. RESULTS: Reliability of PROMIS F-SF scores was adequate across samples, ranging from .72 in the pregnancy sample to .88 in healthy controls. Unidimensionality was supported in each sample. Concurrent validity was strong; across the groups, correlations with scores on the Multidimensional Fatigue Symptom Inventory-Short Form and Brief Fatigue Inventory ranged from .60 to .85. Correlations of the PROMIS F-SF with measures of stress and depressive mood were moderate to strong, ranging from .37 to .64. PROMIS F-SF scores were significantly higher in clinical samples compared to healthy controls. DISCUSSION: Reliability and validity of the PROMIS F-SF were acceptable. The PROMIS F-SF is a suitable measure of fatigue across the four diverse clinical populations included in the analysis.

Comparison of Low Back Pain Recovery and Persistence: A Descriptive Study of Characteristics at Pain Onset.

BACKGROUND: Persistent low back pain is a significant problem worldwide. Early identification and treatment of individuals at high risk for persistent low back pain have been suggested as strategies to decrease the rate of disability associated with this condition. PURPOSE: To examine and compare demographic, pain-related, psychological, and somatosensory characteristics in a cohort of participants with acute low back pain who later went on to experience persistent low back pain or whose pain resolved within the first 6 weeks after initial onset. METHODS: A descriptive study was conducted among men and women 18-50 years of age who had an acute episode of low back pain. Study questionnaires were administered to collect demographic information and measures of pain, coping, reactivity, mood, work history and satisfaction, and disability. A standardized protocol of quantitative sensory testing was performed on each participant at the painful area of their low back and at a remote site on their arm. RESULTS: The sample consisted of 48 participants, of whom 19 went on to develop persistent low back pain and 29 resolved. Compared to the resolved group, the persistent low back pain group was significantly older and had a lower level of educational attainment, a higher body mass index, and higher mean "least" pain score on the Brief Pain Inventory-Short Form. Significantly higher thermal detection thresholds at the painful and remote sites as well as signs of central sensitivity differentiated the persistent pain group from the resolved group during the acute stage of low back pain.
