Randomized trial of an integrated care intervention among Latino adults: Sustained effects on diabetes management.

We examined the 12-month maintenance effects of a previously successful integrated model of diabetes care at improving glycemic management and psychological well-being among Latino adults with type 2 diabetes (T2D). A randomized controlled trial (2015-19) compared an integrated care intervention (ICI) with usual care among 456 adults with T2D. The ICI included integrated medical and behavioral care and health education over 6 months. Assessments were completed at baseline, 3, 6, 9, and 12 months. Most participants were female (63.7%) with a mean age of 55.7 years. In multilevel models, significant Group × Time (quadratic) interaction effects were found for HbA1c [Bint = 0.10, 95% confidence interval (CI) 0.02, 0.17, P < .01] and anxiety symptoms (Bint = 0.20, 95% CI 0.05, 0.35, P < .009), but not depression symptoms (Bint = 0.15, 95% CI -0.01, 0.31, P < .07). Analyses of instantaneous rate of change in the ICI group showed significant decreases at 3 and 6 months for both HbAc1 (B = -0.31 at 3 months; B = -0.12 at 6 months) and anxiety symptoms (B = -0.92 at 3 months; B = -0.46 at 6 months), and no significant instantaneous changes at 9 or 12 months, suggesting that initial improvements were largely maintained. The usual care group showed a small decrease in anxiety symptoms at 6 months (B = -0.17), but no other significant changes at any time-point for anxiety or HbA1c (all Ps > .05). This culturally tailored integrated care model shows potential in producing and sustaining positive effects on clinical and psychological outcomes above standard care.

Our previous studies found that a culturally adapted, enhanced service (integrated care intervention) that we developed improved glycemic management and decreased depression and anxiety symptoms over the 6 months that the service was offered. In this study, we examined whether those improvements in diabetes management and depression and anxiety symptoms were maintained up to 6 months after the conclusion of the intervention. The integrated care intervention involved providing medical and behavioral healthcare on the same day and at the same location as well as health education for 6 months. The study participants were 456 Latino adults (aged 23­80 years) who had type 2 diabetes and were not taking insulin. Participants were randomly assigned to one of two groups: the integrated care intervention or usual care. In this study, we found that the improvements in glycemic management and in anxiety and depression symptoms previously shown were largely maintained. These findings suggest that culturally adapted health services that include both medical and behavioral care and health education programs may benefit Latino patients with type 2 diabetes.

Hub-and-Spoke centralized intervention to optimize colorectal cancer screening and follow-up: A pragmatic, cluster-randomized controlled trial protocol.

BACKGROUND: Guidelines recommend screening for colorectal cancer (CRC), but participation and abnormal test follow up rates are suboptimal, with disparities by demography. Evidence-based interventions exist to promote screening, but community adoption and implementation are limited. METHODS: The San Diego Accelerating Colorectal Cancer Screening and Follow-up through Implementation Science (ACCSIS) program is an academic-community partnership testing regional implementation of a Hub-and-Spoke model for increasing CRC screening and follow-up. The "hub" is a non-academic, non-profit organization that includes 17 community health center (CHC) systems, serving over 190 rural and urban clinic sites. The "spokes" are 3 CHC systems that oversee 11-28 clinics each, totaling over 60 clinics. Using a cluster-randomized trial design, 9 clinics were randomized to intervention and 16 to usual care. Within intervention clinics, approximately 5000 eligible patients not up-to-date with CRC screening per year were identified for intervention. Interventions include an invitation primer, a mailed fecal immunochemical test with completion instructions, and phone and text-based reminders (hub) and patient navigation protocol to promote colonoscopy completion after abnormal FIT (spoke). Outcomes include: 1) proportion of patients up-to-date with screening after three years in intervention versus non-intervention clinics; 2) proportion of patients with abnormal FIT completing colonoscopy within six months of the abnormal result. Implementation science measures are collected to assess acceptability, intervention and usual care adaptations, and sustainability of the intervention strategies. CONCLUSION: This large-scale, regional cluster randomized trial among CHCs serving diverse populations is anticipated to accelerate progress in CRC prevention in underserved populations. TRIAL REGISTRATION: NCT04941300.

Exploring classes of cancer patient navigators and determinants of navigator role retention.

BACKGROUND: In the current nationwide study, the authors used latent class analysis (LCA) to identify classes of cancer patient navigators (CPNs) and examined whether class membership and 12 indicators were related to navigator role retention. METHODS: By using data from 460 CPNs in the United States, LCA identified classes (ie, homogenous subgroups) of CPNs with the following indicators: type of CPN (clinical vs nonclinical), education level, area(s) of the cancer care continuum in which the CPN provided patient navigation, region and urbanity where the CPN provided services, organizational work setting, and patient navigation program funding source. The associations of navigator retention with class membership and each indicator were examined using χ2 tests. RESULTS: LCA identified 3 classes of CPNs. Classes 1 and 3 were conceptualized as distinct, homogeneous subgroups of clinical CPNs that appeared to differ mainly on their likelihood of engagement in outreach, survivorship, palliative care, and end-of-life patient navigation. Class 2 was conceptualized as a nonclinical CPN subgroup that was distinct primarily based on their high endorsement of employment in programs, which are at least partially funded by grants and engagement in earlier stages of patient navigation (eg, early detection). The provision of survivorship and treatment patient navigation was related to navigator role retention, with senior CPNs providing these patient navigation services more than novice CPNs. CONCLUSIONS: The current study highlights 3 distinct classes of CPNs, provides initial information regarding determinants of navigator retention, and makes several recommendations for future patient navigation research.

Health, Psychological and Demographic Predictors of Depression in People with Fibromyalgia and Osteoarthritis.

Depression is common in people with fibromyalgia (FM) and osteoarthritis (OA) and has been linked to adverse health outcomes in these conditions. The purpose of this study was to examine differences in predictors of depression among individuals with FM and OA using a range of health, demographic, and psychological variables. Of the total 963 participants, 600 were diagnosed with FM, and 363 with OA. The Quality of Well-Being Scale (QWB) was used to assess health status. The Fibromyalgia Impact Questionnaire (FIQ) and the Arthritis Impact Measurement Scale (AIMS) were used to measure disease-specific impact. Additionally, participants completed self-efficacy and helplessness assessments. Depression was measured using the Center for Epidemiological Studies Scale (CES-D). The results of a moderated linear regression showed that higher depression scores were associated with lower health status and a greater condition impact, especially in the FM group. Self-efficacy and helplessness predicted depression in both groups, but more strongly in FM. White participants with OA were more depressed than their non-White counterparts, while the opposite was true for FM. These findings indicate that improving health status and psychological well-being might alleviate depression in both FM and OA.

Psychosocial and neighborhood correlates of health-related quality of life: A multi-level study among Hispanic adults.

OBJECTIVE: Improvement in health-related quality of life (HRQoL) is a public health goal of Healthy People 2020. Hispanics living in the United States are at risk for poor HRQoL, but the causes and correlates of this risk are not well understood. Thus, the present study examined individual-level psychosocial and neighborhood-level built environment correlates of physical and mental HRQoL among Hispanic adults. METHOD: A community sample of Hispanic adults (N = 383) completed self-report health-related questionnaires, and census tract was used to collect data on neighborhood-level built environment variables. Multilevel modeling was used to examine individual-level psychosocial (language preference, religiosity, subjective social status, discrimination, and number of years lived in the United States) and neighborhood-level built-environment (the retail food environment, proximity to alcohol retailers, and tobacco retailer density) correlates of physical and mental HRQoL. RESULTS: Higher subjective social status was significantly associated with better HRQoL, and more experiences with discrimination were significantly associated with lower HRQoL. For physical HRQoL, these relationships were stronger in neighborhoods with a higher density of tobacco retail outlets. CONCLUSIONS: Findings from this study suggest that subjective social status and discrimination play important roles in HRQoL among Hispanics, in particular in neighborhoods with a higher density of tobacco retail outlets. This study highlights the importance of considering neighborhood context, and in particular neighborhood disadvantage, when examining the relationship between social status, discrimination and HRQoL among Hispanics.

Sleep disturbance and cancer-related fatigue symptom cluster in breast cancer patients undergoing chemotherapy.

PURPOSE: Sleep disturbance and cancer-related fatigue (CRF) are among the most commonly reported symptoms associated with breast cancer and its treatment. This study identified symptom cluster groups of breast cancer patients based on multidimensional assessment of sleep disturbance and CRF prior to and during chemotherapy. METHODS: Participants were 152 women with stage I-IIIA breast cancer. Data were collected before chemotherapy (T1) and during the final week of the fourth chemotherapy cycle (T2). Latent profile analysis was used to derive groups of patients at each timepoint who scored similarly on percent of the day/night asleep per actigraphy, the Pittsburgh Sleep Quality Index global score, and the five subscales of the Multidimensional Fatigue Symptom Inventory-Short Form. Bivariate logistic regression evaluated if sociodemographic/medical characteristics at T1 were associated with group membership at each timepoint. RESULTS: Three groups (Fatigued with sleep complaints, Average, Minimal symptoms) were identified at T1, and five groups (Severely fatigued with poor sleep, Emotionally fatigued with average sleep, Physically fatigued with average sleep, Average, Minimal symptoms) at T2. The majority of individuals in a group characterized by more severe symptoms at T1 were also in a more severe symptom group at T2. Sociodemographic/medical variables at T1 were significantly associated with group membership at T1 and T2. CONCLUSIONS: This study identified groups of breast cancer patients with differentially severe sleep disturbance and CRF symptom profiles prior to and during chemotherapy. Identifying groups with different symptom management needs and distinguishing groups by baseline sociodemographic/medical variables can identify patients at risk for greater symptom burden.

Efficacy of problem-solving therapy for spouses of men with prostate cancer: A randomized controlled trial.

OBJECTIVE: Prostate cancer can have a significant negative impact on patients and their spouses. Problem-solving therapy (PST) has been shown to help reduce distress and improve quality of life among cancer and caregiver populations. This study tested the efficacy of PST for spouses of men with prostate cancer. METHODS: Spouses of men diagnosed with prostate cancer within the past 18 months (N = 164) were randomly assigned to PST (n = 78) or usual psychosocial care (UPC; n = 86). Spouses completed measures of constructive and dysfunctional problem solving, cancer-related distress, mood, physical and mental health, and dyadic adjustment at preintervention and post-intervention and 3-month post-intervention follow-up. RESULTS: Constructive problem solving increased from pre-intervention to post-intervention among spouses receiving PST but not for spouses receiving UPC; this was maintained at follow-up. There was no decrease in dysfunctional problem solving. Spouses receiving PST versus UPC reported less cancer-related distress post-intervention and at follow-up. There were no significant changes in mood or physical and mental health. Dyadic adjustment was significantly better for spouses receiving PST versus UPC at post-intervention but not at follow-up. Improvements in constructive problem solving mediated better mood and dyadic adjustment post-intervention. CONCLUSIONS: Results support the efficacy of PST for improving spouses' constructive problem solving. There was evidence of both direct and mediated positive effects of PST for both individual and dyadic adjustment. PST may be useful for improving individual and dyadic outcomes for spouses of men with prostate cancer.

Perceptions of Cancer Risk/Efficacy and Cancer-Related Risk Behaviors: Results From the HCHS/SOL Sociocultural Ancillary Study.

This study evaluated the associations among perceived risk, perceived efficacy, and engagement in six cancer-related risk behaviors in a population-based Hispanic/Latino sample. Interviews were conducted with 5,313 Hispanic/Latino adults as part of the Hispanic Community Health Study/Study of Latinos (HCHS/SOL) Sociocultural Ancillary Study. Participants were recruited from the study's four field centers (Bronx, NY; Chicago, IL; Miami, FL; San Diego, CA) between February 2010 and June 2011. Perceived risk and perceived efficacy were assessed with questions drawn from the Health Interview National Trends Survey. More than half of the sample endorsed perceived risk of cancer associated with the six evaluated behaviors, as well as general perceived efficacy for preventing cancer. Adjusted logistic regression analyses demonstrated significant differences across Hispanic/Latino background groups for perceived risk associated with high consumption of alcohol and saturated fat, low consumption of fruits and vegetables, and insufficient exercise but not with smoking or low consumption of fiber. Differences were also found for the belief, "It seems like everything causes cancer" but not for other perceived efficacy items. Perceived cancer risk and perceived efficacy for preventing cancer were neither independently nor interactively associated with engagement in cancer-related risk behaviors after controlling for sociodemographic covariates. Results suggest that perceptions of risk and efficacy with regard to cancer vary across Hispanic/Latino background groups, and therefore background group differences should be considered in prevention efforts. Perceived risk and perceived efficacy were not related to cancer-related risk behaviors among Hispanics/Latinos. Further work is needed to evaluate determinants of cancer-related risk in this population.

Perceived Treatment Need and Latent Transitions in Heroin and Methamphetamine Polydrug Use among People who Inject Drugs in Tijuana, Mexico.

People who inject drugs (PWID) in Tijuana, Mexico, use heroin and/or methamphetamine. While polydrug use is associated with HIV risk behavior, less is known about the stability of polydrug use patterns over time and how polydrug use is related to perceived treatment need. Within a cohort of PWID in Tijuana (N = 735) we sought to (1) characterize subgroups of polydrug and polyroute use from baseline to six months; (2) determine the probabilities of transitioning between subgroups; and (3) examine whether self-reported need for help for drug use modified these transition probabilities. Latent transition analysis (LTA) identified four latent statuses: heroin-only injection (38% at both baseline and follow-up); co-injection of heroin with methamphetamine (3% baseline, 15% follow-up); injection of heroin and methamphetamine (37% baseline, 32% follow-up); and polydrug and polyroute users who injected heroin and both smoked and injected methamphetamine (22% baseline, 14% follow-up). Heroin-only injectors had the highest probability of remaining in the same latent status at follow-up. The majority reported great or urgent need for treatment (51%) and these PWID had greater odds of transitioning to a higher-risk status at follow-up, emphasizing the need for evidence-based drug treatment options for PWID.

Polydrug Use and HIV Risk Among People Who Inject Heroin in Tijuana, Mexico: A Latent Class Analysis.

BACKGROUND: Although most people who inject drugs (PWID) in Tijuana, Mexico, primarily inject heroin, injection and non-injection use of methamphetamine and cocaine is common. We examined patterns of polydrug use among heroin injectors to inform prevention and treatment of drug use and its health and social consequences. METHODS: Participants were PWID residing in Tijuana, aged ≥18 years who reported heroin injection in the past six months and were recruited through respondent-driven sampling (n = 1,025). Latent class analysis was conducted to assign individuals to classes on a probabilistic basis, using four indicators of past six-month polydrug and polyroute use: cocaine injecting, cocaine smoking or snorting, methamphetamine injecting, and methamphetamine smoking or snorting. Latent class membership was regressed onto covariates in a multinomial logistic regression. RESULTS: Latent class analyses testing 1, 2, 3, and 4 classes were fit, with the 3-class solution fitting best. Class 1 was defined by predominantly heroin use (50.2%, n = 515); class 2 by methamphetamine and heroin use (43.7%, n = 448), and class 3 by methamphetamine, cocaine, and heroin use (6.0%, n = 62). Bivariate and multivariate analyses indicated a group of methamphetamine and cocaine users that exhibited higher-risk sexual practices and lower heroin injecting frequency, and a group of methamphetamine users who were younger and more likely to be female. CONCLUSIONS: Discrete subtypes of heroin PWID were identified based on methamphetamine and cocaine use patterns. These findings have identified subtypes of heroin injectors who require more tailored interventions to reduce the health and social harms of injecting drug use.

Patterns of drug use, risky behavior, and health status among persons who inject drugs living in San Diego, California: a latent class analysis.

BACKGROUND: Among persons who inject drugs (PWID), polydrug use (the practice of mixing multiple drugs/alcohol sequentially or simultaneously) increases risk for HIV transmission and unintentional overdose deaths. Research has shown local drug markets influence drug use practices. However, little is known about the impact of drug mixing in markets dominated by black tar heroin and methamphetamine, such as the western United States. METHODS: Data were collected through an ongoing longitudinal study examining drug use, risk behavior, and health status among PWID. Latent class analysis (LCA) was used to identify patterns of substance use (heroin, methamphetamine, prescription drugs, alcohol, and marijuana) via multiple administration routes (injecting, smoking, and swallowing). Logistic regression was used to identify behaviors and health indicators associated with drug use class. RESULTS: The sample included 511 mostly white (51.5%) males (73.8%), with mean age of 43.5 years. Two distinct classes of drug users predominated: methamphetamine by multiple routes (51%) and heroin by injection (49%). In multivariable logistic regression, class membership was associated with age, race, and housing status. PWID who were HIV-seropositive and reported prior sexually transmitted infections had increased odds of belonging to the methamphetamine class. Those who were HCV positive and reported previous opioid overdose had an increased odds of being in the primarily heroin injection class (all P-values < .05). CONCLUSION: Risk behaviors and health outcomes differed between PWID who primarily inject heroin vs. those who use methamphetamine. The findings suggest that in a region where PWID mainly use black tar heroin or methamphetamine, interventions tailored to sub-populations of PWID could improve effectiveness.

Strategies that predict weight loss among overweight/obese young adults.

OBJECTIVES: Understanding the characteristics of young adults who have difficulty achieving a healthy weight may help develop more effective interventions. METHODS: Signal detection was conducted to identify subgroups of overweight/obese young adults more or less likely to lose weight (5% weight loss) over 6 months. Data were collected from a diverse sample involved in a randomized controlled behavioral weight loss intervention (N = 404). RESULTS: Overall, 15% (N = 57) of participants achieved <5% weight loss. Change in self-monitoring weight, baseline score of gym attendance/participating in exercise classes, and change in eating less fat were the best predictors of weight loss. CONCLUSION: These strategies may be particularly helpful to promote short-term weight loss in overweight/obese young adults.

Associations of chronic stress burden, perceived stress, and traumatic stress with cardiovascular disease prevalence and risk factors in the Hispanic Community Health Study/Study of Latinos Sociocultural Ancillary Study.

OBJECTIVE: The current study examined multiple stress indicators (chronic, perceived, traumatic) in relation to prevalent coronary heart disease, stroke, and major cardiovascular disease (CVD) risk factors (i.e., diabetes, dyslipidemia, hypertension, and current smoking) in the multisite Hispanic Community Health Study/Study of Latinos Sociocultural Ancillary Study (2010-2011). METHODS: Participants were 5313 men and women 18 to 74 years old, representing diverse Hispanic/Latino ethnic backgrounds, who underwent a comprehensive baseline clinical examination and sociocultural examination with measures of stress. RESULTS: Chronic stress burden was related to a higher prevalence of coronary heart disease after adjusting for sociodemographic, behavioral, and biological risk factors (odds ratio [OR; 95% confidence interval], 1.22 [1.10-1.36]) and related to stroke prevalence in the model adjusted for demographic and behavioral factors (OR [95% confidence interval], 1.26 [1.03-1.55]). Chronic stress was also related to a higher prevalence of diabetes (OR = 1.20 [1.11-1.31]) and hypertension (OR = 1.10 [1.02-1.19]) in individuals free from CVD (n = 4926). Perceived stress (OR = 1.03 [1.01-1.05]) and traumatic stress (OR = 1.15 [1.05-1.26]) were associated with a higher prevalence of smoking. Participants who reported a greater number of lifetime traumatic events also unexpectedly showed a lower prevalence of diabetes (OR = 0.89 [0.83-0.97]) and hypertension (OR = 0.88 [0.82-0.93]). Effects were largely consistent across age and sex groups. CONCLUSIONS: The study underscores the advantages of examining multiple indicators of stress in relation to health because the direction and consistency of associations may vary across distinct stress conceptualizations. In addition, the study suggests that chronic stress is related to higher CVD risk and prevalence in Hispanics/Latinos, the largest US ethnic minority group.

Testing the invariance of adolescent survey-based smoking-related behaviors across ethnic groups and gender.

The present study examined the factor structure of 3 smoking-related items administered as part of the California Health Interview Survey. Factorial invariance was examined across Asian Americans (N = 377), Caucasians (N = 1739), African Americans (N = 115), and Latin Americans (N = 814), and across young men (N = 1612) and women (N = 1767). Factorial invariance analyses revealed all minority ethnic groups to be significantly different (p < .05) from Caucasians, and men to differ significantly from women. These findings suggest that the types of smoking behaviors assessed in the California Health Interview Survey do not predict behaviors uniformly across groups.

Physical function and quality of well-being in fibromyalgia: the applicability of the goodness-of-fit hypothesis.

Objective: The goodness-of-fit hypothesis suggests that the effectiveness of a coping strategy depends on the match between type of strategy (problem-focused, emotion-focused) and the level of perceived control. This hypothesis was examined as a predictor of physical functioning and quality of well-being (QWB) in a large sample of women with fibromyalgia. Methods: Participants were 478 women with diagnosed fibromyalgia (Mage = 54.31, SD = 11.2), who were part of a larger intervention in which no intervention effects were found. Hierarchical, mixed selection regressions were performed to determine whether the relationship between coping and control-predicted physical functioning and QWB. Results: Participants who reported having lower levels of perceived control over their fibromyalgia syndrome and who engaged in more self-controlling coping (emotion-focused strategy) experienced greater QWB and physical functioning than those who used less self-controlling coping. Various main effects for coping and perceived control were also found. Level of physical functioning was also related to escape-avoidance, distancing, and perceived control. The level of QWB was related to social-support seeking, accepting responsibility, distancing, problem-solving, and perceived control. Conclusions: This study provides a greater understanding of the relationships among coping, perceived control, physical functioning, and well-being for women with fibromyalgia. Implications and directions for future research are discussed.

Telephone Surveys Underestimate Cigarette Smoking among African-Americans.

BACKGROUND: This study tested the hypothesis that data from random digit-dial telephone surveys underestimate the prevalence of cigarette smoking among African-American adults. METHOD: A novel, community-sampling method was used to obtain a statewide, random sample of N = 2118 California (CA) African-American/Black adults, surveyed door-to-door. This Black community sample was compared to the Blacks in the CA Health Interview Survey (N = 2315), a statewide, random digit-dial telephone survey conducted simultaneously. RESULTS: Smoking prevalence was significantly higher among community (33%) than among telephone survey (19%) Blacks, even after controlling for sample differences in demographics. CONCLUSION: Telephone surveys underestimate smoking among African-Americans and probably underestimate other health risk behaviors as well. Alternative methods are needed to obtain accurate data on African-American health behaviors and on the magnitude of racial disparities in them.

Assessment of daily and weekly fatigue among African American cancer survivors.

This investigation evaluates two common measures of cancer-related fatigue, one multidimensional/retrospective and one unidimensional/same day. Fifty-two African American survivors of diverse cancers completed fatigue visual analogue scales once daily, and the Multidimensional Fatigue Symptom Inventory-Short Form (MFSI-SF) once weekly, for four weeks. Zero-order correlations showed retrospective fatigue was significantly related to average, peak, and most recent same-day fatigue. Multilevel random coefficient modeling showed unidimensional fatigue shared the most variance with the MFSI-SF's General subscale for three weeks, and with the Vigor subscale for one week. Researchers and clinicians may wish to prioritize multidimensional measures when assessing cancer-related fatigue, if appropriate.

Individual and neighborhood socioeconomic status and inflammation in Mexican American women: what is the role of obesity?

OBJECTIVE: Inflammation may represent a biological mechanism underlying associations of socioeconomic status (SES) with cardiovascular disease. We examined relationships of individual and neighborhood SES with inflammatory markers in Mexican American women and evaluated contributions of obesity and related heath behaviors to these associations. METHODS: Two hundred eighty-four Mexican American women (mean age = 49.74 years) were recruited from socioeconomically diverse South San Diego communities. Women completed measures of sociodemographic characteristics and health behaviors, and underwent a physical examination with fasting blood draw for assay of plasma C-reactive protein (CRP), interleukin 6 (IL-6), and soluble intercellular adhesion molecule 1 (sICAM-1). Neighborhood SES was extracted from the US Census Bureau 2000 database. RESULTS: In multilevel models, a 1-standard deviation higher individual or neighborhood SES related to a 27.35% and 23.56% lower CRP level (p values < .01), a 7.04% and 5.32% lower sICAM-1 level (p values < .05), and a 10.46% (p < .05) and 2.40% lower IL-6 level (not significant), respectively. Controlling for individual SES, a 1-standard deviation higher neighborhood SES related to a 18.05% lower CRP level (p = .07). Differences in body mass index, waist circumference, and dietary fat consumption contributed significantly to SES-inflammation associations. CONCLUSIONS: The findings support a link between SES and inflammatory markers in Mexican American women and implicate obesity and dietary fat in these associations. Additional effects of neighborhood SES were not statistically significant; however, these findings should be viewed tentatively due to the small sample size to evaluate contextual effects. Trial Registration ClinicalTrials.gov identifier: NCT00387166.

Complementary medicine for fatigue and cortisol variability in breast cancer survivors: a randomized controlled trial.

BACKGROUND: Fatigue is a chief complaint in cancer patients, and warrants effective treatment. Biofield therapies are complementary medicine approaches used by cancer populations. There is little information about their efficacy. METHODS: This blinded, randomized controlled trial examined the effects of 4 weeks (eight 1-hour sessions) of biofield healing compared with mock healing and a waitlist control group on fatigue in 76 fatigued breast cancer survivors (stages I-IIIa). Secondary outcomes were diurnal cortisol variability (via estimates of cortisol slope), depression, and quality of life (QOL). Treatment belief was assessed to explore whether belief predicted outcomes. Data were analyzed via hierarchical linear modeling. RESULTS: There were no significant differences between biofield healing and mock healing on belief; 75% thought they received biofield healing. Compared with controls, biofield healing significantly decreased total fatigue (P < .0005, Cohen's d = 1.04), as did mock healing (P = .02, Cohen's d = 0.68), with no significant differences between biofield healing and mock healing. Cortisol slope significantly decreased for biofield healing versus both mock healing and control (P < .04 in both cases; Cohen's d = 0.58). Belief predicted changes in QOL over and above group (P = .004, Cohen's d = 0.84). Belief did not impact fatigue or cortisol variability. CONCLUSIONS: Nonspecific factors are important in responses to biofield interventions for fatigue. Belief predicts QOL responses but not fatigue or cortisol variability. Biofield therapies increase cortisol variability independent of belief and other nonspecific factors. There is a need to further examine the effects of specific processes of biofield healing on outcomes for cancer populations.

Typologies of recanting of lifetime cigarette, alcohol and marijuana use during a six-year longitudinal panel study.

AIM: To identify if there are different typologies for adolescent self-reporters and recanters for alcohol, cigarette and marijuana use. METHODS: This study is a secondary data analysis and utilized four waves of the National Longitudinal Survey of Youth child panel data. The study included adolescents aged ten and older who self-reported ever use of cigarettes (n=872), marijuana (n=854) or alcohol (n=837). Consistent responders were those who reported lifetime use of a specific substance and continued to report such use at each latter wave of data collection. Latent class analyses were utilized to investigate if there are different types of self-reporters for each substance class. RESULTS: Three unique groups for each substance was identified. The first group of users, who had a late age of onset, tended to be consistent self-reporters across waves. Those who were early onset users of cigarettes and marijuana tended to recant their use while early onset alcohol users were consistent reporters. Those with moderate ages of onset had no consistent recanting patterns. The highest degree of recanting was found among the early onset marijuana users. CONCLUSIONS: The results suggest that youth who begin their use at an earlier age may not be as reliable reporters as youth who initiate use at later ages. Our results suggest that the veracity of prevalence estimates for licit and illicit substances could be different depending on the age of the respondent.
