Cancer-related fatigue: A systematic and meta-analytic review of non-pharmacological therapies for cancer patients.

[Correction Notice: An erratum for this article was reported in Vol 135(1) of Psychological Bulletin (see record 2008-18777-005). The URL to the Supplemental Materials for the article is listed incorrectly in two places in the text. The incorrect listings appear on p. 704 (in the last two lines of the third paragraph) and on p. 705 (in the third and fourth lines of the first paragraph in the second column). The correct URL for the Supplemental Materials is http://dx.doi.org/10.1037/a0012825.supp, which is provided on the first page of the article beneath the abstract.] Cancer-related fatigue (CRF) is a significant clinical problem for more than 10 million adults diagnosed with cancer each year worldwide. No gold standard treatment presently exists for CRF. To provide a guide for future research to improve the treatment of CRF, the authors conducted the most comprehensive combined systematic and meta-analytic review of the literature to date on non-pharmacological (psychosocial and exercise) interventions to ameliorate CRF and associated symptoms (vigor/vitality) in adults with cancer, based on 119 randomized controlled trials (RCTs) and non-RCT studies. Meta-analyses conducted on 57 RCTs indicated that exercise and psychological interventions provided reductions in CRF, with no significant differences between these 2 major types of interventions considered as a whole. Specifically, multimodal exercise and walking programs, restorative approaches, supportive-expressive, and cognitive-behavioral psychosocial interventions show promising potential for ameliorating CRF. The results also suggest that vigor and vitality are distinct phenomena from CRF with regard to responsiveness to intervention. With improved methodological approaches, further research in this area may soon provide clinicians with effective strategies for reducing CRF and enhancing the lives of millions of cancer patients and survivors.

"Systematic review and meta-analysis of psychological and activity-based interventions for cancer-related fatigue": Correction.

Reports an error in "Systematic review and meta-analysis of psychological and activity-based interventions for cancer-related fatigue" by Paul B. Jacobsen, Kristine A. Donovan, Susan T. Vadaparampil and Brent J. Small (Health Psychology, 2007[Nov], Vol 26[6], 660-667). The text directing readers to view supplementary materials online was omitted. That information is provided here: "Supplementary materials to this article may be viewed at: http://dx.doi.org/10.1037/0278-6133.26.6.660.supp." (The following abstract of the original article appeared in record 2007-16656-002.) Context: Fatigue is among the most common and distressing symptoms experienced by cancer patients. Objective: This systematic review and meta-analysis evaluates the efficacy of psychological and activity-based interventions against cancer-related fatigue in cancer patients. Data Sources: MEDLINE, PsycINFO, and CINAHL. Study Selection: Randomized controlled trials of psychological and activity-based interventions involving adult cancer patients in which fatigue was an outcome were reviewed. Extraction: Forty-one trials were reviewed and 30 were included in a meta-analysis. Data Synthesis: Fifty percent of psychological trials and 44% of activity-based trials rated fair or better in quality yielded significant findings favoring the intervention condition. Meta-analysis yielded an overall effect size of 0.09 (95% CI = .02- .16) favoring nonpharmacological conditions. Further analysis indicated that effect sizes were significant for psychological interventions (dw = .10, 95% CI = .02-.18) but not activity-based interventions (dw = .05, 95% CI = -.08 - .19). Conclusions: Findings provide limited support for use of nonpharmacological interventions to manage cancer-related fatigue. The lack of research with heightened fatigue as an eligibility criterion is a notable weakness of the existing evidence base. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

"Conscientiousness and reactions to psychological contract breach: A longitudinal field study": Correction to Orvis, Dudley, & Cortina (2008).

Reports an error in "Conscientiousness and reactions to psychological contract breach: A longitudinal field study" by Karin A. Orvis, Nicole M. Dudley and Jose M. Cortina (Journal of Applied Psychology, 2008[Sep], Vol 93[5], 1183-1193). Six correlations in Table 1 on page 1187 are incorrectly reported. A corrected table is presented in the erratum, with corrected values in bold. (The following abstract of the original article appeared in record 2008-12803-015.) The authors examined the role of employee conscientiousness as a moderator of the relationships between psychological contract breach and employee behavioral and attitudinal reactions to the breach. They collected data from 106 newly hired employees within the 1st month of employment (Time 1), 3 months later (Time 2), and 8 months after Time 1 (Time 3) to observe the progression through contract development, breach, and reaction. Results suggest that conscientiousness is a significant moderator for 4 of the 5 contract breach-employee reaction relationships examined (turnover intentions, organizational loyalty, job satisfaction, and 1 of 2 facets of job performance). Specifically, employees who were lower in conscientiousness had more negative reactions to perceived breach with respect to turnover intentions, organizational loyalty, and job satisfaction. In contrast, employees who were higher in conscientiousness reduced their job performance to a greater degree in response to contract breach. Future research directions are discussed.

"Early withdrawal from mental health treatment: Implications for psychotherapy practice": Correction to Barrett et al (2008).

Reports an error in "Early withdrawal from mental health treatment: Implications for psychotherapy practice" by Marna S. Barrett, Wee-Jhong Chua, Paul Crits-Christoph, Mary Beth Gibbons and Don Thompson (Psychotherapy: Theory, Research, Practice, Training, 2008[Jun], Vol 45[2], 247-267). The fourth author’s name was mistakenly left out of the author byline and table of contents. The correct author listing for this article is presented in the erratum. (The following abstract of the original article appeared in record 2008-07317-011.) Despite more than 50 years of research on client attrition from therapy, obstacles to the delivery and success of treatments remain poorly understood, and effective methods to engage and retain clients in therapy are lacking. This article offers a review of the literature on attrition, highlighting the methodological challenges in effectively addressing the complex nature of this problem. Current interventions for reducing attrition are reviewed, and recommendations for implementing these interventions into psychotherapy practice are discussed.

"Solving XOR": Correction to Grand and Honey (2008).

Reports an error in "Solving XOR" by C. Grand and R. C. Honey (Journal of Experimental Psychology: Animal Behavior Processes, 2008[Oct], Vol 34[4], 486-493). Figure 2 in the article was printed incorrectly due to an editing error. The correct version of Figure 2 is provided in the erratum. (The following abstract of the original article appeared in record 2008-14849-005.) Three experiments examined the way in which exclusive-or (XOR) problems are solved by rats. All rats first received food-rewarded positive and negative patterning problems with two stimulus sets: either A+, B+, AB- and C-, D-, CD+, or A-, B-, AB + and C+, D +, and CD-. Subsequently, rats received revaluation trials in which A was paired with shock and C was not, prior to generalization test trials with B, D, AB, and CD (Experiments 1 & 2); or received A→shock trials prior to tests with B and CD (Experiment 3). There was greater generalized fear to B than to either D (Experiments 1 & 2) or AB (Experiment 2) and CD (Experiments 2 & 3). These results are inconsistent with configural, connectionist models, but are consistent with an alternative connectionist model that can represent the logical structure of XOR problems.

The Cognitive Interview: A meta-analytic review and study space analysis of the past 25 years.

The Cognitive Interview (CI) is a well-established protocol for interviewing witnesses. The current article presents a study space analysis of laboratory studies of the CI together with an empirical meta-analysis summarizing the past 25 years of research. The study space comprises 57 published articles (65 experiments) on the CI, providing an assessment of the boundary conditions underlying the analysis and application of this interview protocol. The current meta-analysis includes 46 published articles, including 20 articles published since the last meta-analysis conducted a decade earlier (K?hnken, Milne, Memon, & Bull, 1999). Reassuringly for practitioners, the findings of the original meta-analysis were replicated with a large and significant increase in correct details and a small increase in errors. In addition we found that there were no differences in the rate at which details are confabulated. Importantly, the effect sizes were unaffected by the inclusion of recent studies using modified versions of the CI. The CI appeared to benefit older adult witnesses even more than younger adults. We highlight trends and gaps in research and discuss how our findings can inform policy and training decisions. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Meta-analyses and systematic reviews of psychological treatments for chronic pain: Relevance to an evidence-based practice.

As evidence-based practitioners become more reliant on systematic reviews to inform treatment, it becomes important to systematize reporting details as well as improve the quality of the primary studies that will later be incorporated into this secondary literature. In this article, the authors consider several specific factors that can serve this function in the area of chronic pain: (a) adhering to a standardized set of reporting standards; (b) measuring a standardized set of short- and long-term outcome variables; (c) providing information about individual differences; and (d) providing detailed, easily accessible documentation of the treatment program (or progams). The article also highlights ways that practitioners and researchers can collaborate on treatment outcome research, thereby improving the ability to discover and disseminate effective treatments for patients who suffer from chronic pain.

"Affect dynamics, affective forecasting, and aging": Correction to Nielsen, Knutson, and Carstensen (2008).

Reports an error in "Affect dynamics, affective forecasting, and aging" by Lisbeth Nielsen, Brian Knutson and Laura L. Carstensen (Emotion, 2008[Jun], Vol 8[3], 318-330). The first author of the article was listed as being affiliated with both the National Institute on Aging and the Department of Psychology, Stanford University. Dr. Nielsen would like to clarify that the research for this article was conducted while she was a postdoctoral fellow at Stanford University. The copyright notice should also have been listed as "In the Public Domain." (The following abstract of the original article appeared in record 2008-06717-002.) Affective forecasting, experienced affect, and recalled affect were compared in younger and older adults during a task in which participants worked to win and avoid losing small monetary sums. Dynamic changes in affect were measured along valence and arousal dimensions, with probes during both anticipatory and consummatory task phases. Older and younger adults displayed distinct patterns of affect dynamics. Younger adults reported increased negative arousal during loss anticipation and positive arousal during gain anticipation. In contrast, older adults reported increased positive arousal during gain anticipation but showed no increase in negative arousal on trials involving loss anticipation. Additionally, younger adults reported large increases in valence after avoiding an anticipated loss, but older adults did not. Younger, but not older, adults exhibited forecasting errors on the arousal dimension, underestimating increases in arousal during anticipation of gains and losses and overestimating increases in arousal in response to gain outcomes. Overall, the findings are consistent with a growing literature suggesting that older people experience less negative emotion than their younger counterparts and further suggest that they may better predict dynamic changes in affect.

Emotional distress following genetic testing for hereditary breast and ovarian cancer: A meta-analytic review.

Objective: Meta-analysis was used to synthesize results of studies on emotional consequences of predictive genetic testing for BRCA1/2 mutations conferring increased risk of breast and ovarian cancer. Design: Studies assessing anxiety or cancer-specific distress before and after provision of test results (k = 20) were analyzed using a random-effects model. Moderator variables included country of data collection and personal cancer history of study participants. Main Outcome Measures: Standardized mean gain effect sizes were calculated for mutation carriers, noncarriers, and those with inconclusive results over short (0–4 weeks), moderate (5–24 weeks), or long (25–52 weeks) periods of time after testing. Results: Distress among carriers increased shortly after receiving results and returned to pretesting levels over time. Distress among noncarriers and those with inconclusive results decreased over time. Some distress patterns differed in studies conducted outside the United States and for individuals with varying cancer histories. Conclusion: Results underscore the importance of time; changes in distress observed shortly after test-result disclosure frequently differed from the pattern of distress seen subsequently. Although emotional consequences of this testing appear minimal, it remains possible that testing may affect cognitive and behavioral outcomes, which have rarely been examined through meta-analysis. Testing may also affect understudied subgroups differently. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

"Searching for the second generation of American women psychologists": Correction to Johnston and Johnson (2008).

Reports an error in "Searching for the second generation of American women psychologists" by Elizabeth Johnston and Ann Johnson (History of Psychology, 2008[Feb], Vol 11[1], 40-72). The authors would like to indicate that Inez Beverly Prosser's academic degree was incorrectly listed as EdD in the Appendix. Prosser's correct degree is PhD. (The following abstract of the original article appeared in record 2008-04777-003.) As a consequence of the groundbreaking work of E. Scarborough and L. Furumoto (1987), the contributions of the pioneering first generation of American women psychologists are now well recognized within the history of psychology; however, the generation that followed the pioneers is less well known. The lack of recognition that most women psychologists of the interwar era experienced during the majority of their working lives resulted from sexism institutionalized through practices such as anti-nepotism rules that effectively excluded many married women from the academy, informal hiring practices operating in "old-boy network" fashion, and exclusion from certain key graduate training centers. Yet, many women were productive psychologists during this era and contributed to the growth and expansion of the discipline. Examination of published literature generated biographical information for 107 eminent women; C. A. Murchison's (1932b) Psychological Register provided a less detailed but more inclusive inventory to yield data on a total of 320 women. This article recounts our systematic search for this "lost generation" and emphasizes the extent and diversity of their contributions to psychology.

Newcomer adjustment during organizational socialization: A meta-analytic review of antecedents, outcomes, and methods.

The authors tested a model of antecedents and outcomes of newcomer adjustment using 70 unique samples of newcomers with meta-analytic and path modeling techniques. Specifically, they proposed and tested a model in which adjustment (role clarity, self-efficacy, and social acceptance) mediated the effects of organizational socialization tactics and information seeking on socialization outcomes (job satisfaction, organizational commitment, job performance, intentions to remain, and turnover). The results generally supported this model. In addition, the authors examined the moderating effects of methodology on these relationships by coding for 3 methodological issues: data collection type (longitudinal vs. cross-sectional), sample characteristics (school-to-work vs. work-to-work transitions), and measurement of the antecedents (facet vs. composite measurement). Discussion focuses on the implications of the findings and suggestions for future research. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

"Subtle mind, open heart: Mike Arons remembered (1929-2008)": Correction to Richards & Whitehouse (2008).

Reports an error in Subtle mind, open heart: Mike Arons remembered (1929-2008) by Ruth Richards and Howard Whitehouse (Psychology of Aesthetics, Creativity, and the Arts, 2008[Nov], Vol 2[4], 264-270). There was a printing error in the quoted passage of the poem Mating of the Gods by Mike Arons. The correct poem passage is presented in the erratum. (The following abstract of the original article appeared in record 2008-16346-010.) Presents an obituary for Myron Milford Arons, a powerful figure in psychology and an advocate of open inquiry, authenticity, and truth. He was a psychologist, philosopher, existentialist, one of the founders of humanistic psychology, an early scholar of creativity from his dissertation at the Sorbonne and later work with mentor Abraham Maslow, and a strong advocate of qualitative along with quantitative methodologies.

"Perceived group devaluation, depression, and HIV-risk behavior among Asian gay men": Correction to Chae and Yoshikawa (2008).

Reports an error in "Perceived group devaluation, depression, and HIV-risk behavior among Asian gay men" by David H. Chae and Hirokazu Yoshikawa (Health Psychology, 2008[Mar], Vol 27[2], 140-148). In the aforementioned article, the second sentence of the Results portion of the abstract should read: Among participants most attracted to Whites, group devaluation was associated with higher levels of nonprimary partner UAI; but was associated with lower levels of nonprimary partner UAI among those most attracted to non-Whites. (The following abstract of the original article appeared in record 2008-03424-002.) Objective: This study examined depressive mood and HIV-risk behavior in relation to perceived group devaluation and group identity. Design: Cross-sectional survey of 192 Asian gay men. Main Outcome Measures: Depressive mood assessed using the Centers for Epidemiological Studies Depression Scale (CES-D) and self-reported receptive or insertive unprotected anal intercourse (UAI) in the past 3 months. Results: Group devaluation was positively associated with depressive mood. Among participants most attracted to Whites, group devaluation was associated with higher levels of nonprimary partner UAI, among those most attracted to non-Whites. Among participants reporting higher levels of group devaluation, those with more positive personal evaluations of the Asian gay community had lower levels of total UAI compared to those with more negative personal evaluations of the Asian gay community. Conclusions: Results suggest that group devaluation is associated with higher levels of depressive mood among Asian gay men. Asian gay men most attracted to non-Whites or hold more positive evaluations of their group may be buffered from the influence of high perceived group devaluation on UAI.

The contributions of parental attachment bonds to college student development and adjustment: A meta-analytic review.

We report findings from a meta-analysis of 156 studies conducted between 1987 and 2009 (N = 32,969) that examined the relationship between self-reported parental attachment and multiple adjustment outcomes and developmental advances during the college years. Overall, a small-to-medium relationship was found between indicators of parental attachment quality and favorable adjustment outcomes (r = .23). Effect sizes were of similar magnitude for mother and father attachment relationships, for male and female students, and across ethnicity and nationality of the sample. The attachment–adjustment relationship varied somewhat according to the developmental task being investigated in the study, showing the strongest association for the task of separation–individuation. Additionally, we found stronger attachment–adjustment links for students residing away from their parents when compared with students living at home during college.

"Chronic psychosocial factors and acute physiological responses to laboratory-induced stress in healthy populations: A quantitative review of 30 years of investigations": Correction to Chida and Hamer (2008).

Reports an error in "Chronic psychosocial factors and acute physiological responses to laboratory-induced stress in healthy populations: A quantitative review of 30 years of investigations" by Yoichi Chida and Mark Hamer (Psychological Bulletin, 2008[Nov], Vol 134[6], 829-885). There is an error in Table 1. On p. 840 the entry for Hill et al. 1987 should be Masters et al. 2004. (The following abstract of the original article appeared in record 2008-14745-003.) This meta-analysis included 729 studies from 161 articles investigating how acute stress responsivity (including stress reactivity and recovery of hypothalamic-pituitary-adrenal [HPA] axis, autonomic, and cardiovascular systems) changes with various chronic psychosocial exposures (job stress; general life stress; depression or hopelessness; anxiety, neuroticism, or negative affect; hostility, aggression, or Type-A behavior; fatigue, burnout, or exhaustion; positive psychological states or traits) in healthy populations. In either the overall meta-analysis or the methodologically strong subanalysis, positive psychological states or traits were associated with reduced HPA reactivity. Hostility, aggression, or Type-A behavior was associated with increased cardiovascular (heart rate or blood pressure) reactivity, whereas anxiety, neuroticism, or negative affect was associated with decreased cardiovascular reactivity. General life stress and anxiety, neuroticism, or negative affect were associated with poorer cardiovascular recovery. However, regarding the sympathetic nervous system and parasympathetic nervous system, there were no associations between the chronic psychosocial factors and stress reactivity or recovery. The results largely reflect an integrated stress response pattern of hypo- or hyperactivity depending on the specific nature of the psychosocial background.

An algorithm for identifying nonsystematic delay-discounting data: Correction to Johnson and Bickel (2008).

Reports an error in An algorithm for identifying nonsystematic delay-discounting data by Matthew W. Johnson and Warren K. Bickel (Experimental and Clinical Psychopharmacology, 2008[Jun], Vol 16[3], 264-274). Several misprints occurred and should read as follows: 1) Warren K. Bickel is with the University of Arkansas for Medical Sciences. It appears correctly in this erratum. 2) The first sentence in the abstract should read Several discounting studies have used the R2 measure to identify data with poor fits to a mathematical discounting model as nonsystematic data to be eliminated. 3) In Table 2, the last row of column one should read Madden opioid. 4) In the last line of the caption of Figure 2, though should read through. (The following abstract of the original article appeared in record 2008-06716-009.) Several previous discounting studies have use the R2 measure to identify data sets with poor fits to a mathematical discounting model as nonsystematic data to be eliminated before further analyses are conducted. Data from three previous delay-discounting studies (six separate groups, with a total of 161 individuals) were used to demonstrate why using R2 to assess the fits of discounting data is problematic. A significant, positive correlation between discounting rate parameter and R2 was found in most groups, showing that R2 is more stringent as a measure of fit for low discounting rates than for high discounting rates. Furthermore, it is suggested that identifying nonsystematic data based on any measure of fit to a mathematical discounting model may be problematic because it confounds discounting rate comparison with the issue of discounting model assessment. Therefore, a model-free method to identify nonsystematic data is needed. An algorithm for identifying nonsystematic data is presented that is based on the expectation of a monotonically decreasing discounting function. This algorithm identified 13 cases out of the 161 reanalyzed data sets as nonsystematic. These nonsystematic data are presented, along with examples of data not identified as nonsystematic. This algorithm, or modifications of it, may be useful in a variety of human and nonhuman animal discounting studies (e.g., delay discounting, probability discounting) as an alternative to the R2 measure for identifying nonsystematic data. The algorithm may be used in empirical investigations to improve discounting methodology, and may be used to identify outliers to be removed from analyses.

Antipathetic relationships in child and adolescent development: A meta-analytic review and recommendations for an emerging area of study.

Antipathetic relationships, or relationships based on mutual dislike, have received less attention than other aspects of children’s peer relations. The present meta-analytic review summarizes the existing literature (26 studies consisting of over 23,000 children and adolescents) to illuminate the prevalence of antipathetic relationships and their associations with maladjustment. Results indicate that 35% of children have an antipathetic relationship and that antipathetic relationships are associated with externalizing and internalizing problems, low academic achievement, low prosocial behavior, victimization and rejection by peers, and lower positive peer regard (e.g., social preference) and friendships. Gender differences in antipathetic relationships are trivial, and antipathetic relationships are equally often same and mixed gender. Collectively, the findings indicate the importance of studying antipathetic relationships, and several directions for future research are described.

"Effect sizes for experimenting psychologists": Correction to Rosnow and Rosenthal (2003).

Reports an error in "Effect sizes for experimenting psychologists" by Ralph L. Rosnow and Robert Rosenthal (Canadian Journal of Experimental Psychology/Revue canadienne de psychologie expérimentale, 2003[Sep], Vol 57[3], 221-237). A portion of the note to Table 1 was incorrect. The second sentence of the note should read as follows: Fisher’s ?r is the log transformation of r, that is, ? loge [(1 + r)/(1 - r)]. (The following abstract of the original article appeared in record 2003-08374-009.) [Correction Notice: An erratum for this article was reported in Vol 63(1) of Canadian Journal of Experimental Psychology/Revue canadienne de psychologie expérimentale (see record 2009-03064-004). Correction for Note in TABLE 1 (on page 222): The second sentence should read as follows: Fisher’s zr is the log transformation of r, that is, 1?2 loge[(1 + r)/(1 ? r)].] This article describes three families of effect size estimators and their use in situations of general and specific interest to experimenting psychologists. The situations discussed include both between- and within-group (repeated measures) designs. Also described is the counternull statistic, which is useful in preventing common errors of interpretation in null hypothesis significance testing. The emphasis is on correlation (r-type) effect size indicators, but a wide variety of difference-type and ratio-type effect size estimators are also described.

"The lasting effect of words on feelings: Words may facilitate exposure effects to threatening images": Correction to Tabibnia, Lieberman, and Craske (2008).

Reports an error in "The lasting effect of words on feelings: Words may facilitate exposure effects to threatening images" by Golnaz Tabibnia, Matthew D. Lieberman and Michelle G. Craske (Emotion, 2008[Jun], Vol 8[3], 307-317). The URL provided for the supplemental materials was incorrect. The correct URL is provided in the erratum. (The following abstract of the original article appeared in record 2008-06717-001.) Previous studies have shown that mere words, particularly affective words, can dampen emotional responses. However, the effect of affective labels on emotional responding in the long term is unknown. The authors examined whether repeated exposure to aversive images would lead to more reduction in autonomic reactivity a week later if the images were exposed with single-word labels than without labels. In Experiment 1, healthy individuals were exposed to pictures of disturbing scenes with or without labels on Day 1. On Day 8, the same pictures from the previous week were exposed, this time without labels. In Experiment 2, participants were spider fearful and were exposed to pictures of spiders. In both experiments, although repeated exposure to aversive images (without labels) led to long-term attenuation of autonomic reactivity, exposure plus affective labels, but not nonaffective labels, led to more attenuation than exposure alone. Thus, affective labels may help dampen emotional reactivity in both the short and long terms. Implications for exposure therapy and translational studies are discussed.
