A critical reanalysis of the relationship between genomics and well-being.

Fredrickson et al. [Fredrickson BL, et al. (2013) Proc Natl Acad Sci USA 110(33):13684-13689] claimed to have observed significant differences in gene expression related to hedonic and eudaimonic dimensions of well-being. Having closely examined both their claims and their data, we draw substantially different conclusions. After identifying some important conceptual and methodological flaws in their argument, we report the results of a series of reanalyses of their dataset. We first applied a variety of exploratory and confirmatory factor analysis techniques to their self-reported well-being data. A number of plausible factor solutions emerged, but none of these corresponded to Fredrickson et al.'s claimed hedonic and eudaimonic dimensions. We next examined the regression analyses that purportedly yielded distinct differential profiles of gene expression associated with the two well-being dimensions. Using the best-fitting two-factor solution that we identified, we obtained effects almost twice as large as those found by Fredrickson et al. using their questionable hedonic and eudaimonic factors. Next, we conducted regression analyses for all possible two-factor solutions of the psychometric data; we found that 69.2% of these gave statistically significant results for both factors, whereas only 0.25% would be expected to do so if the regression process was really able to identify independent differential gene expression effects. Finally, we replaced Fredrickson et al.'s psychometric data with random numbers and continued to find very large numbers of apparently statistically significant effects. We conclude that Fredrickson et al.'s widely publicized claims about the effects of different dimensions of well-being on health-related gene expression are merely artifacts of dubious analyses and erroneous methodology.

Exploring synergistic interactions and catalysts in complex interventions: longitudinal, mixed methods case studies of an optimised multi-level suicide prevention intervention in four european countries (Ospi-Europe).

BACKGROUND: The Medical Research Council (MRC) Framework for complex interventions highlights the need to explore interactions between components of complex interventions, but this has not yet been fully explored within complex, non-pharmacological interventions. This paper draws on the process evaluation data of a suicide prevention programme implemented in four European countries to illustrate the synergistic interactions between intervention levels in a complex programme, and to present our method for exploring these. METHODS: A realist evaluation approach informed the process evaluation, which drew on mixed methods, longitudinal case studies. Data collection consisted of 47 semi-structured interviews, 12 focus groups, one workshop, fieldnoted observations of six programme meetings and 20 questionnaires (delivered at six month intervals to each of the four intervention sites). Analysis drew on the framework approach, facilitated by the use of QSR NVivo (v10). Our qualitative approach to exploring synergistic interactions (QuaSIC) also developed a matrix of hypothesised synergies that were explored within one workshop and two waves of data collection. RESULTS: All four implementation countries provided examples of synergistic interactions that added value beyond the sum of individual intervention levels or components in isolation. For instance, the launch ceremony of the public health campaign (a level 3 intervention) in Ireland had an impact on the community-based professional training, increasing uptake and visibility of training for journalists in particular. In turn, this led to increased media reporting of OSPI activities (monitored as part of the public health campaign) and also led to wider dissemination of editorial guidelines for responsible reporting of suicidal acts. Analysis of the total process evaluation dataset also revealed the new phenomenon of the OSPI programme acting as a catalyst for externally generated (and funded) activity that shared the goals of suicide prevention. CONCLUSIONS: The QuaSIC approach enabled us to develop and refine our definition of synergistic interactions and add the innovative concept of catalytic effects. This represents a novel approach to the evaluation of complex interventions. By exploring synergies and catalytic interactions related to a complex intervention or programme, we reveal the added value to planned activities and how they might be maximised.

Role of patient treatment beliefs and provider characteristics in establishing patient-provider relationships.

BACKGROUND: Positive patient-provider relationships have been associated with improved depression treatment outcomes. Little is known about how patient treatment beliefs influence patient-provider relationships, specifically treatment alliance and shared decision making in primary care (PC). OBJECTIVE: We evaluated the relationship between patient treatment beliefs and patient-provider relationships by gender, race and current depression. METHODS: We used a deductive parallel convergent mixed method design with cross-sectional data. Participants were 227 Black and White patients presenting with depression symptoms in PC settings. Individuals were randomized into either a quantitative survey (n = 198) or qualitative interview (n = 29) group. We used multiple ordinary least squares regression to evaluate the association between patient beliefs, as measured by the Treatment Beliefs Scale and the Medication Beliefs Scale, and treatment alliance or shared decision making. We concurrently conducted thematic analyses of qualitative semistructured interview data to explicate the nature of patient-provider relationships. RESULTS: We found that patients who believed their provider would respectfully facilitate depression treatment reported greater bond, openness and shared decision making with their provider. We also identified qualitative themes of physicians listening to, caring about and respecting patients. Empathy and emotive expression increased patient trust in PC providers as facilitators of depression treatment. CONCLUSIONS: This work systematically demonstrated what many providers anecdotally believe: PC environments in which individuals feel safe sharing psychological distress are essential to early identification and treatment of depression. Interprofessional skills-based training in attentiveness and active listening may influence the effectiveness of depression intervention.

A Quantitative Test of an Implementation Framework in 38 VA Residential PTSD Programs.

This study examines the implementation of two evidence-based psychotherapies, Prolonged Exposure (PE) and Cognitive Processing Therapy (CPT), in the Department of Veterans Affairs residential Posttraumatic Stress Disorder treatment programs. Two hundred and one providers from 38 programs completed an online survey concerning implementation of PE delivered on an individual basis and CPT delivered in individual and group formats. For PE, a supportive organizational context (dedicated time and resources, and incentives and mandates) and overall positive view of the treatment were related to its implementation. For both group and individual CPT, only the supportive organizational context was significantly associated with outcome. Implications for implementation efforts are discussed.

Evaluation of an implementation model: a national investigation of VA residential programs.

This national investigation utilizes qualitative data to evaluate an implementation model regarding factors influencing provider use of two evidence-based treatments for posttraumatic stress disorder (PTSD). Semi-structured qualitative interviews with 198 mental health providers from 38 Department of Veterans Affairs' (VA) residential treatment programs were used to explore these issues regarding prolonged exposure (PE) and cognitive processing therapy (CPT) in VA residential PTSD programs. Several unique and some overlapping predictors emerged. Leadership was viewed as an influence on implementation for both CPT and PE, while a lack of dedicated time and resources was viewed as a deterrent for both. Compatibility of CPT with providers' existing practices and beliefs, the ability to observe noticeable patient improvement, a perceived relative advantage of CPT over alternative treatments, and the presence of a supportive peer network emerged as influential on CPT implementation. Leadership was associated with PE implementation. Implications for the design and improvement of training and implementation efforts are discussed.

Is implementing screening for distress an efficient means to recruit patients to a psychological intervention trial?

OBJECTIVES: Psychological interventions show greater efficacy when evaluated with distressed patients. We report on the feasibility of implementing screening for recruiting distressed cancer patients to a randomized controlled trial of problem-solving therapy (PST), characteristics associated with enrolment, and time investment and challenges of implementing screening. METHODS: Three medical settings implemented screening of patients, directly after cancer treatment (T1) and 2 months later (T2), using Hopkins Symptom Checklist-25 and one question about need for services. Distressed patients indicating need for services were interviewed. Eligible patients were offered the possibility to participate in the trial. Consenting patients were randomized to PST or waitlist. RESULTS: At T1, 366 of 970 screened patients (37%) scored above the cutoff and at T2, 208 of 689 screened patients (30%). At either or both T1 and T2, 423 patients reported distress, of whom 215 indicated need for services. Only 36 (4% of 970) patients consented to trial participation. Twenty-seven patients needed to be screened to recruit a single patient, with 17 h required for each patient recruited. Barriers to screening were time constraints and negative attitudes of oncology staff towards screening. CONCLUSIONS: Implementing screening proved inefficient for recruiting distressed cancer patients post-treatment to a randomized controlled trial on PST, with need for services being much less than anticipated. Consecutively screening patients did not result in a sample representative of the larger pool of distressed patients, which may lower generalizability. An adequately powered intervention trial using screening requires a feasibility study establishing recruitment rates and dedicated, funded staff assistance.

Triple P-Positive Parenting programs: the folly of basing social policy on underpowered flawed studies.

Wilson et al. provided a valuable systematic and meta-analytic review of the Triple P-Positive Parenting program in which they identified substantial problems in the quality of available evidence. Their review largely escaped unscathed after Sanders et al.'s critical commentary. However, both of these sources overlook the most serious problem with the Triple P literature, namely, the over-reliance on positive but substantially underpowered trials. Such trials are particularly susceptible to risks of bias and investigator manipulation of apparent results. We offer a justification for the criterion of no fewer than 35 participants in either the intervention or control group. Applying this criterion, 19 of the 23 trials identified by Wilson et al. were eliminated. A number of these trials were so small that it would be statistically improbable that they would detect an effect even if it were present. We argued that clinicians and policymakers implementing Triple P programs incorporate evaluations to ensure that goals are being met and resources are not being squandered.Please see related articles http://www.biomedcentral.com/1741-7015/10/130 and http://www.biomedcentral.com/1741-7015/10/145.

Is screening effective in detecting untreated psychiatric disorders among newly diagnosed breast cancer patients?

BACKGROUND: A key purpose of routine distress screening is to ensure that cancer patients receive appropriate mental health care. Most studies validating screening instruments overestimate the effectiveness of screening by not differentiating between patients with untreated disorders and patients who are already being treated. This study adopts the novel strategy of evaluating the effectiveness of screening after correcting for disorder for which treatment is already being provided. METHODS: A total of 437 recently diagnosed breast cancer patients received in-clinic distress screening and telephone-based psychiatric interviews. Analyses were conducted using receipt of psychotropic medication for mental health difficulties in the context of a psychiatric disorder as a proxy for identification and treatment. RESULTS: Rates of elevated distress (33%), major depressive disorder (8%), minor depression (6%), dysthymia (2%), or generalized anxiety disorder (3%) were similar to those in other samples. Thirty-six percent of patients received psychotropic medication around the time of cancer diagnosis, including 64% of those with a current psychiatric diagnosis. Although 39% of patients with elevated distress had a psychiatric disorder, the positive predictive value of screening fell to 15% for an untreated psychiatric disorder and 6% had untreated depression. CONCLUSION: Given the high rates of existing treatment, screening may not be efficient for identifying untreated disorder. Almost two-thirds of patients with treated disorders remain symptomatic. Use of symptom scales might reasonably be expanded to surveillance of treatment response or ruling out disorder. Substantial resources would likely be required to coordinate or manage psychiatric care among patients, as would a willingness to intervene in existing relationships with other providers.

Lack of prognostic value of type D personality for mortality in a large sample of heart failure patients.

BACKGROUND: Type D personality has been proposed as a prognostic indicator for mortality in cardiovascular disease. Most research examining this construct originates from one research group, and it is critical that the predictive value of Type D personality for adverse outcomes is independently cross-validated. This study examined its prognostic value in heart failure, relative to B-type natriuretic peptide (BNP) and depressive symptoms. METHODS: We studied 706 patients with complete BNP, depressive symptom, and Type D personality and mortality data from 958 patients with heart failure enrolled after hospitalization for a multisite study of a disease management program. Multivariable models were adjusted for BNP and depression. RESULTS: At 18 months, there were 192 deaths (27.2%). No evidence was found for a prognostic value of Type D personality in the unadjusted model (hazard ratio [HR] = 0.893, 95% confidence interval [CI] = 0.582-1.370). In contrast, BNP was significantly predictive of mortality (HR = 1.588, 95% CI = 1.391-1.812), whereas depression was not (HR = 1.011, 95% CI = 0.998-1.024). Type D was also not predictive in covariate-adjusted models (HR = 0.779, 95% CI = 0.489-1.242). Similar results were obtained when analyzing Type D as the interaction between continuous z scores of its two components, negative affectivity and social inhibition (p = .144). CONCLUSIONS: In the largest study to date, Type D does not predict mortality. Future research should construe Type D as the interaction of continuous negative affectivity and social inhibition z scores, rather than as a typology, and consider analyses replacing negative affectivity with depression.

Does screening for distress efficiently uncover meetable unmet needs in cancer patients?

OBJECTIVES: We evaluated screening for distress in terms of its ability to uncover unmet need for psychosocial services in cancer patients. Correlates of distress, need for services and met and unmet need for services were investigated. METHODS: Immediately after cancer treatment (T1) and 2 months later (T2), 302 patients completed the Hopkins Symptom Checklist-25 (HSCL-25) and a single question assessing the need for services. All distressed patients (HSCL-25≥39) and non-distressed patients endorsing a need for services were then called (n = 99) to assess their need. RESULTS: Thirty-seven percent (T1) and 31% (T2) of patients were distressed and 31% (T1) and 18% (T2) expressed the need for services. Both time points showed higher distress in younger patients and females and lower distress in prostate cancer and patients treated by radiotherapy only. Less need for services was found in prostate cancer (T1), greater need was related to being single (T1) and younger (T2). Distress and need for services were positively related (p<0.001). The HSCL-25 showed modest sensitivity (T1: 0.59, T2: 0.65) and specificity (T1: 0.75, T2: 0.78) as an indicator of need for services. Interviews at T2 revealed that 51% of distressed patients needed no psychosocial services and 25% were already receiving services. At T2, regardless of distress level, 10% of all screened patients reported an unmet need for psychosocial services. CONCLUSIONS: Depending on the clinical context, screening might be more efficient if it assessed the unmet need for services rather than distress. More attention should be concentrated on directing patients with meetable unmet needs to available services.

Detection of depression in older adults by family and friends: distinguishing mood disorder signals from the noise of personality and everyday life.

BACKGROUND: The capacity of friends and family member informants to make judgments about the presence of a mood disorder history in an older primary care patient has theoretical, clinical, and public health significance. This study examined the accuracy of informant-reported mood disorder diagnoses in a sample of primary care patients aged 65 years or older. We hypothesized that the accuracy (sensitivity and specificity) of informant reports would vary with the patient's personality. METHODS: Hypotheses were tested in 191 dyads consisting of patients and their friends or relatives (informants) recruited from primary care settings. Gold-standard mood disorder diagnoses were established at consensus conferences based on a review of medical charts and data collected in a structured interview with the patient. Patients completed an assessment battery that included the NEO-Five Factor Inventory. RESULTS: Sensitivity and specificity of informant-derived mood disorder diagnoses were related to patient personality. Sensitivity of informant-derived lifetime mood disorder diagnoses was compromised by higher Extraversion and higher Agreeableness. Specificity of informant-derived lifetime mood disorder diagnoses was compromised by lower Agreeableness and higher Conscientiousness. CONCLUSION: Patient personality has implications for the accuracy of mood disorder histories provided by friends and family members. Given that false negatives can have grave consequences, we recommend that practitioners be particularly vigilant when interpreting collateral information about their extraverted, agreeable patients.

Reporting of conflicts of interest in meta-analyses of trials of pharmacological treatments.

CONTEXT: Disclosure of conflicts of interest (COIs) from pharmaceutical industry study funding and author-industry financial relationships is sometimes recommended for randomized controlled trials (RCTs) published in biomedical journals. Authors of meta-analyses, however, are not required to report COIs disclosed in original reports of included RCTs. OBJECTIVE: To investigate whether meta-analyses of pharmacological treatments published in high-impact biomedical journals report COIs disclosed in included RCTs. DATA SOURCES AND STUDY SELECTION: We selected the 3 most recent meta-analyses of patented pharmacological treatments published January 2009 through October 2009 in each general medicine journal with an impact factor of at least 10; in high-impact journals in each of the 5 specialty medicine areas with the greatest 2008 global therapeutic sales (oncology, cardiology, respiratory medicine, endocrinology, and gastroenterology); and in the Cochrane Database of Systematic Reviews. DATA EXTRACTION: Two investigators independently extracted data on disclosed study funding, author-industry financial ties, and author employment from each meta-analysis, from RCTs included in each meta-analysis, and on whether meta-analyses reported disclosed COIs of included RCTs. RESULTS: Of 29 meta-analyses reviewed, which included 509 RCTs, only 2 meta-analyses (7%) reported RCT funding sources; and 0 reported RCT author-industry ties or employment by the pharmaceutical industry. Of 318 meta-analyzed RCTs that reported funding sources, 219 (69%) were industry funded; and 91 of 132 (69%) that reported author financial disclosures had 1 or more authors with pharmaceutical industry financial ties. In 7 of the 29 meta-analyses reviewed, 100% of included RCTs had at least 1 form of disclosed COI (pharmaceutical industry funding, author-industry financial ties, or employment), yet only 1 of these 7 meta-analyses reported RCT funding sources, and 0 reported RCT author-industry ties or employment. CONCLUSION: Among a group of meta-analyses of pharmacological treatments published in high-impact biomedical journals, information concerning primary study funding and author COIs for the included RCTs were only rarely reported.

Negotiating depression treatment with older adults: primary care providers' perspectives.

BACKGROUND: Primary care occupies a strategic position in the evaluation and treatment of depression in late life, yet many older patients do not initiate or adhere to treatments available in primary care. AIM: To explore how primary care providers describe the process of discussing depression care with older adults. METHOD: Semi-structured interviews conducted with 15 providers involved with intervention studies of depression management for older adults. We used the constant comparative method to identify themes related to negotiating the treatment of depression with older adults. RESULTS: Providers felt that older patients often attribute depression to non-medical causes. They talked about the challenges and described the need to 'convince' them of the medical model of depression. CONCLUSION: How primary care physicians surmise patients' views of depression may influence the discussion of depression in practice. As medication is most often provided for depression treatment, some may feel compelled to convince their patients of biomedical explanations while others may avoid treating depression altogether.

Invited commentary: personality as a causal factor in cancer risk and mortality--time to retire a hypothesis?

In this issue of the Journal, Nakaya et al. (Am J Epidemiol. 2010;172(4):377-385) report null findings from a large-scale prospective study of the prognostic value of 2 personality dimensions, neuroticism and extraversion, for cancer risk and mortality. The study stands out because of its exceptionally large sample size and its methodological strengths. The authors discuss the Nakaya et al. study in the context of persistent beliefs about the role of personality in cancer onset and survival despite a pattern of null findings in the literature, as well as the influence of extreme outlier findings from one investigator group that continue to be cited. They question whether it is time for the field to move on from considering a role for personality in cancer to more promising and modifiable factors.

Sociocultural determinants of men's reactions to prostate cancer diagnosis.

OBJECTIVE: To develop a better understanding of how men react to being diagnosed with prostate cancer and identify factors that influence these responses, we conducted an observational study to identify sociocultural predictors of men's psychological reactions. METHODS: Participants were 70 African American and 124 white prostate cancer patients who completed a structured telephone interview that evaluated psychological reactions in terms of intrusive thoughts about cancer and attempts to avoid cancer-related thoughts and feelings. Perceptions of disease-specific stress, cultural beliefs and values, and social constraints were also assessed during the interview. RESULTS: There were no racial differences in men's reactions to being diagnosed with prostate cancer; however, greater perceptions of disease-specific stress, increasing levels of present temporal orientation, and more social constraints had significant positive effects on avoidant reactions. Greater perceptions of stress also had a significant positive effect on intrusive thoughts. CONCLUSIONS: The results of this study highlight the need for individualized approaches to help men address their thoughts and feelings about being diagnosed with prostate cancer. These efforts should include strategies that help men to communicate more effectively with social support resources and address cultural beliefs and values related to temporal orientation.

A randomized, controlled study of Internet peer-to-peer interactions among women newly diagnosed with breast cancer.

OBJECTIVE: Peer-to-peer interactions are associated with enhanced psychosocial adjustment among women with breast cancer. Millions of women with cancer and others with various health conditions use the Internet to establish peer relationships, usually without professional moderation. This paper reports findings from the first randomized, controlled study of the benefits of these types of Internet-based peer interactions. METHODS: This pilot study involved seventy-eight women who were recently diagnosed with breast cancer. Participants were randomly assigned to either an Internet peer support condition or Internet-based educational control condition. Data were gathered at baseline and 4- and 12-months. Primary outcomes of interest were psychological distress and quality of life. RESULTS: Contrary to hypotheses, participants in the Internet peer support condition tended to do worse over time on primary outcome measures. There were no differences between groups on secondary outcomes of perceived social support, self-efficacy, or hope. Paradoxically, many women in the Internet peer support condition actively participated and reported high levels of satisfaction, suggesting some self-perceived benefits. CONCLUSIONS: These results suggest that Internet based peer-to-peer interactions may not necessarily be universally beneficial despite the positive experiences reported by many participants. Further research is needed to understand the magnitude of this effect with a larger sample. Moreover, these results raise questions about the need to understand the comparative effectiveness of Internet-based communications by group structure (i.e., unstructured/structured; unmoderated/moderated) and the effect of content (i.e., expression of fear/anxiety, insightful disclosures, etc.) on outcomes.

Positive psychology in cancer care: bad science, exaggerated claims, and unproven medicine.

BACKGROUND: Claims of positive psychology about people with cancer enjoy great popularity because they seem to offer scientific confirmation of strongly held cultural beliefs and values. PURPOSE: Our goal is to examine critically four widely accepted claims in the positive psychology literature regarding adaptational outcomes among individuals living with cancer. METHODS: We examine: (1) the role of positive factors, such as a "fighting spirit" in extending the life of persons with cancer; (2) effects of interventions cultivating positive psychological states on immune functioning and cancer progression and mortality; and evidence concerning (3) benefit finding and (4) post-traumatic growth following serious illness such as cancer and other highly threatening experiences. RESULTS: Claims about these areas of research routinely made in the positive psychology literature do not fit with available evidence. We note in particular the incoherence of claims about the adaptational value of benefit finding and post-traumatic growth among cancer patients, and the implausibility of claims that interventions that enhance benefit finding improve the prognosis of cancer patients by strengthening the immune system. CONCLUSION: We urge positive psychologists to rededicate themselves to a positive psychology based on scientific evidence rather than wishful thinking.
