Biological and psychological predictors of cognitive function in breast cancer patients before surgery.

PURPOSE: Research suggests that cancer-related cognitive impairment (CRCI) can occur before breast cancer (BC) treatment. The limited extant evidence suggests the underlying mechanisms could be stress-related. Potential psychological and biological predictors of CRCI prior to any BC treatment were examined. METHODS: 112 treatment-naïve women with BC and 67 healthy controls (HC) completed a neuropsychological test battery to assess cognitive impairment and a self-report battery to assess cognitive complaints, cancer-related stress, depressive and anxiety symptoms. Morning and evening cortisol and α-amylase were collected from saliva. Multilinear regressions were conducted. RESULTS: Treatment-naïve BC patients were more frequently impaired in verbal memory and processing speed and reported more cognitive complaints (all p < .001) than HC. BC patients and HC did not differ in overall cognitive impairment (p = .21). Steeper α-amylase, lower cancer-related stress and younger age was associated with better overall cognitive function in treatment-naïve BC patients. Higher depressive symptoms predicted higher levels of cognitive complaints in BC patients. CONCLUSION: Overall, these findings suggest that stress plays a role in CRCI. This study is the first to associate α-amylase with cognitive function in cancer patients, informing future research. The findings on impairment in processing speed and verbal memory among treatment-naïve BC highlight the need to screen for such impairments among BC patients and indicate that future studies on CRCI should include baseline assessments prior to BC treatment. If replicated, these findings could inform the development and testing of appropriate interventions to decrease CRCI among cancer patients.

Psychobiological stress response to a lung cancer diagnosis: a prospective study of patients in Iceland and Sweden.

BACKGROUND: A diagnostic work-up leading to a lung cancer diagnosis is a severely stressful experience that may impact tumor progression. Yet, prospective data are scarce on psychological and biological components of stress at the time of lung cancer diagnosis. The aim of this study was to assess pre-to-post diagnosis change in psychological distress and urinary excretion of catecholamines in patients with suspected lung cancer. METHODS: Participants were 167 patients within the LUCASS study, recruited at referral for suspected lung cancer to University Hospitals in Iceland and Sweden. Patients completed questionnaires on perceived distress (Hospital Anxiety and Depression Scale, HADS) before and after diagnosis of lung cancer or a non-malignant origin. A subpopulation of 85 patients also provided overnight urine for catecholamine analysis before and at a median of 24 days after diagnosis but before treatment. RESULTS: A lung cancer diagnosis was confirmed in 123 (73.7%) patients, with a mean age of 70.1 years. Patients diagnosed with lung cancer experienced a post-diagnosis increase in psychological distress (p = 0.010), while patients with non-malignant lung pathology showed a reduction in distress (p = 0.070). Both urinary epinephrine (p = 0.001) and norepinephrine (p = 0.032) levels were higher before the diagnosis among patients eventually diagnosed with lung cancer compared to those with non-malignant lung pathology. We observed indications of associations between pre-to-post diagnosis changes in perceived distress and changes in urinary catecholamine levels. CONCLUSION: Receiving a lung cancer diagnosis is associated with an increase in psychological distress, while elevated catecholamine levels are evident already before lung cancer diagnosis.

Greater Social Isolation and Social Constraints Prior to Hematopoietic Stem Cell Transplant Are Associated with Greater Anxiety and Depressive Symptoms.

BACKGROUND: Hematopoietic stem cell transplantation (hereafter "HCT") is a physically and psychologically difficult treatment for patients with hematological cancers. This study examined relationships among patients' reports of pre-transplant social isolation, social constraints, and psychological distress. METHOD: We used baseline data from a multisite randomized controlled trial evaluating the effects of expressive helping writing to reduce physical and emotional symptoms in HCT patients. We collected data prior to randomization and before either allogenic or autologous HCT using validated scales to assess social constraints, social isolation, anxiety, and depressive symptoms. We analyzed data using bivariate analysis and multivariate linear regression. We also explored whether social isolation mediated the effect of social constraints on both of our outcomes: anxiety and depressive symptoms. RESULTS: Among 259 adults recruited prior to transplant, 43.6% were women (mean age = 57.42 years, SD = 12.34 years). In multivariate analysis controlling for relevant covariates, both social isolation (ß = 0.24, p < 0.001) and social constraints (ß = 0.28, p < 0.001) were associated with anxiety. When both social constraints and social isolation were in the model, only greater social isolation (ß = 0.79, p < 0.001) was associated with depressive symptoms. Social isolation fully mediated the association between social constraints and anxiety and depressive symptoms. CONCLUSION: For patients awaiting either allogenic or autologous HCT, the negative association between social constraints and anxiety and depressive symptoms may be related, in part, to the mechanism of perceived social isolation. Interventions prior to and during HCT are needed to support patients' psychological health and sense of social connectedness.

An Adaptation, Extension and Pre-Testing of an Interactive Decision Aid for Men Diagnosed with Localized Prostate Cancer in Iceland: A Mixed-Method Study.

In this study an interactive decision aid (DA) for men diagnosed with localized prostate cancer was adapted, extended and pre-tested. The DA's prototype was based on a literature review and other empirically tested DAs. Semi-structured interviews with 12 men (age 65-80) diagnosed with localized prostate cancer were conducted to get feedback on content, usability, and the DA's layout. The interviews were analyzed using thematic analysis and themes were identified using deductive and inductive coding. Participants found the accessibility of the information and the explicit values clarification tool helpful. Four themes were identified: (1) usability and design, (2) content and knowledge, (3) deciding factors of decision-making, and (4) social support. Participants valued receiving extensive and realistic information on surgery/radiation therapy side effects and getting unbiased presentations of treatment options. Following the thematic analysis, the DA was revised and tested in a survey among 11 newly diagnosed prostate cancer patients (age 60-74). The participants valued the DA and found it helpful when making a treatment decision, and all reported that they would recommend it to others making a prostate cancer treatment decision. The DA is currently being tested in a randomized clinical trial (RCT). This is the first DA developed for prostate cancer patients in Iceland and if the results of the RCT show that it is more effective than standard care in assisting newly diagnosed patients with their treatment decision, the DA can be easily translated and adapted to cultures similar to Iceland such as the Nordic countries.

Psychometric evaluation of an Icelandic translation of the adolescent and parent report versions of the BATH pain questionnaires and investigation of the psychosocial impact of pain on adolescents with chronic disease.

Adolescents commonly experience chronic pain, which can have considerable multidimensional effects on their lives, impacting, for example, their school functioning, leisure activities, sleep, and emotional functioning. Therefore, valid and reliable measurements of these multidimensional and potentially adverse effects, reflecting both the adolescents' and parents' perceptions, are essential. At present, no such measures are available in Iceland. The primary aim of the current study was to translate the Bath Adolescent Pain Questionnaire (BAPQ) and the Bath Adolescent Pain Questionnaire parent version (BAPQ-P) and evaluate the psychometric qualities of the Icelandic translation. The study's secondary aim was to investigate the multidimensional impact of chronic pain on adolescents with chronic illness using these instruments. Participants were 45 adolescents (11-16 years old) registered in the medical records of the National University Hospital of Iceland with one of the following diagnoses: (1) Crohn's or colitis (IBD); (2) migraine; or (3) arthritis. Sixty-nine parents of the diagnosed adolescents also participated (a total of 41 adolescent and parent dyads). To establish the psychometric qualities of the BAPQ and BAPQ-P, participants were asked to complete several questionnaires online. The preliminary results showed that the Icelandic translations of the BAPQ and BAPQ-P scales have good psychometric qualities, providing valid and reliable measures to assess the multidimensional effects of chronic pain in adolescents in both clinical and research settings. Moreover, the results showed that chronic pain impacts various domains in the adolescents' lives and that the prevalence of anxiety and depression was quite high among them.

Psychosocial impact of proactive rapid genetic counseling following breast cancer diagnosis.

OBJECTIVE: As germline genetic referral becomes increasingly routine as part of the care of newly diagnosed breast cancer patients, it is important to understand the psychosocial impact of genetic counseling at the time of diagnosis. We examined the psychosocial and quality of life (QOL) impact of providing proactive rapid genetic counseling and testing (RGCT) in the immediate aftermath of a breast cancer diagnosis. METHODS: We randomized 330 patients in a 2:1 ratio to proactive rapid genetic counseling (RGCT; N = 222) versus usual care (UC; N = 108). Participants completed a baseline telephone survey before randomization and definitive surgery and a follow-up survey at 1-month post-randomization. We evaluated the impact of RGCT versus UC on breast cancer genetic knowledge, distress, QOL, and decisional conflict. Given that 43% of UC participants and 86% of RGCT participants completed genetic counseling prior to the 1-month assessment, we also evaluated the impact of genetic counseling participation over and above group assignment. RESULTS: The RGCT intervention led to increased breast cancer genetic knowledge relative to UC but did not differentially impact other study outcomes. Across groups patients who participated in genetic counseling had significantly increased knowledge and improved QOL compared to those who did not participate in genetic counseling. CONCLUSIONS: While prior research has documented the impact of genetic counseling and testing on surgical decisions, these results confirm that participation in genetic counseling at the time of diagnosis can yield improvements in knowledge and QOL in the short-term.

Optimizing use of written peer support as a supportive resource in cancer: Focus group insights.

PURPOSE: Cancer survivors frequently describe wanting to learn from others who have had similar diagnoses or treatments (peer support). We conducted focus groups to investigate hematopoietic stem cell transplant survivors' attitudes and preferences regarding accessing written peer support through a website. Although written peer support does not allow for interpersonal interactions with peers, it could increase transplant recipients' access to evidence-based benefits of informational and emotional peer support. METHODS: We conducted four videoconference focus groups with 34 adult transplant survivors who were diverse in their medical and sociodemographic characteristics and geographic location. Discussions were recorded, transcribed, and content analyzed. RESULTS: Many participants reported need for information about transplant beyond what they received from their healthcare providers. Needs varied across participants, as did preferences for characteristics and timing of information optimally provided through peer support. Participants were enthusiastic about the value of written peer support but emphasized that it should be delivered in a way that accommodates variation in transplant experiences, underscores its trustworthiness, and pairs it with useful psychoeducational content. CONCLUSIONS: Findings provide guidance for making written peer support an accessible, supportive resource for transplant survivors. Future research should evaluate personalized online delivery of written peer support paired with psychoeducational content that enhances its benefits. IMPLICATIONS FOR CANCER SURVIVORS: Written peer support delivered online could be a useful, valued resource for transplant survivors.

Optimal communication associated with lower risk of acute traumatic stress after lung cancer diagnosis.

PURPOSE: The aim of this study was to assess the role of the patient's background and perceived healthcare-related factors in symptoms of acute stress after lung cancer diagnosis. METHODS: The study population consisted of 89 individuals referred for diagnostic work-up at Landspitali National University Hospital in Iceland and subsequently diagnosed with lung cancer. Before diagnosis, the patients completed questionnaires on sociodemographic characteristics, pre-diagnostic distress (Hospital Anxiety and Depression Scale), social support, and resilience. At a median of 16 days after diagnosis, the patients reported symptoms of acute stress on the Impact of Event Scale-Revised (IES-R) and experience of communication and support from healthcare professionals and family during the diagnostic period. RESULTS: Patients were on average 68 years and 52% reported high levels of post-diagnostic acute stress (IES-R > 23) while 24% reported symptoms suggestive of clinical significance (IES-R > 32). Prior history of cancer (ß = 6.7, 95% CI: 0.1 to 13.3) and pre-diagnostic distress were associated with higher levels of post-diagnostic acute stress (ß = 8.8, 95% CI: 2.7 to 14.9), while high educational level (ß = - 7.9, 95% CI: - 14.8 to - 1.1) was associated with lower levels. Controlling for the abovementioned factors, the patients' perception of optimal doctor-patient (ß = - 9.1, 95% CI: - 14.9 to - 3.3) and family communication (ß = - 8.6, 95% CI: - 14.3 to - 2.9) was inversely associated with levels of post-diagnostic acute stress after lung cancer diagnosis. CONCLUSIONS: A high proportion of patients with newly diagnosed lung cancer experience high levels of acute traumatic stress of potential clinical significance. Efforts to improve doctor-patient and family communication may mitigate the risk of these adverse symptoms.

A multi-level developmental approach towards understanding adolescent mental health and behaviour: rationale, design and methods of the LIFECOURSE study in Iceland.

PURPOSE: Identifying and understanding modifiable risk and protective factors that can inform early detection and intervention to prevent adolescent emotional problems and harmful behaviours is among the most pressing modern-day public health challenges. This paper describes the rationale, objectives, methods, and anticipated outcomes of the LIFECOURSE study, a multi-level, bio-psychosocial prospective study designed to advance our understanding of factors that shape adolescent mental health and behaviour. METHODS: Conducted by the Icelandic Centre for Social Research and Analysis at Reykjavik University, LIFECOURSE is a longitudinal population-based developmental study of Icelandic adolescents born in 2004. The study utilizes a comprehensive multi-informant assessment of individual, societal and biological factors measured across the lifespan. Data assembly and collection were conducted from 2016-2020 and utilize both retrospective and prospective data sources: (a) retrospective registry data assembled from seven national databases, (b) prospectively collected social surveys and (c) biomarker samples. RESULTS: Of the 3914 eligible adolescents, 60.8% (n = 2378) provided informed parental consent and student assent to participate in the study, with approximately half of the participants being female (n = 1175, 49.4%) and the majority being born in the capital area (n = 1455; 61.2%). The coverage of available data from the national databases and participation in the social surveys ranged from 81.7 to 100%. CONCLUSIONS: Major gaps remain in our knowledge of how individual, societal and biological factors across the lifespan-from early life to adolescence-interact and shape the risk for emotional problems and harmful behaviours during adolescence. The LIFECOURSE study was designed to address this knowledge gap.

Predictors of contralateral prophylactic mastectomy in genetically high risk newly diagnosed breast cancer patients.

PURPOSE: Recent trends indicate increased use of contralateral prophylactic mastectomy (CPM) among newly diagnosed breast cancer patients, particularly those who test positive for a pathogenic variant in the BRCA1/2 genes. However, the rate of CPM among patients who test negative or choose not to be tested is surprisingly high. We aimed to identify patient predictors of CPM following breast cancer diagnosis among such patients. METHODS: As part of a randomized controlled trial of rapid genetic counseling and testing vs. usual care, breast cancer patients completed a baseline survey within 6 weeks of diagnosis and before definitive surgery. Analyses focused on patients who opted against testing (n = 136) or who received negative BRCA1/2 test results (n = 149). We used multivariable logistic regression to assess the associations between sociodemographic, clinical- and patient-reported factors with use of CPM. RESULTS: Among patients who were untested or who received negative test results, having discussed CPM with one's surgeon at the time of diagnosis predicted subsequent CPM. Patients who were not candidates for breast-conserving surgery and those with higher levels of cancer-specific intrusive thoughts were also more likely to obtain a CPM. CONCLUSION: The strongest predictors of CPM in this population were objective clinical factors and discussion with providers. However, baseline psychosocial factors were also independently related to the receipt of CPM. Thus, although CPM decisions are largely guided by relevant clinical factors, it is important to attend to psychosocial factors when counseling newly diagnosed breast cancer patients about treatment options.

Predictors of genetic testing uptake in newly diagnosed breast cancer patients.

BACKGROUND AND OBJECTIVES: Many newly diagnosed breast cancer patients do not receive genetic counseling and testing at the time of diagnosis. We examined predictors of genetic testing (GT) in this population. METHODS: Within a randomized controlled trial of proactive rapid genetic counseling and testing vs usual care, patients completed a baseline survey within 6 weeks of breast cancer diagnosis but before a definitive survey. We conducted a multinomial logistic regression to identify predictors of GT timing/uptake. RESULTS: Having discussed GT with a surgeon was a dominant predictor (χ2 (2, N = 320) = 70.13; P < .0001). Among those who discussed GT with a surgeon, patients who had made a final surgery decision were less likely to receive GT before surgery compared with postsurgically (OR [odds ratio] = 0.24; 95% confidence interval [CI] = 0.12-0.49) or no testing (OR = 0.28; 95% CI = 0.14-0.56). Older patients (OR = 0.95; 95% CI = 0.91-0.99) and participants enrolled in New York/New Jersey (OR = 0.22; 95% CI = 0.07-0.72) were less likely to be tested compared with receiving results before surgery. Those with higher perceived risk (OR = 1.02; 95% CI = 1.00-1.03) were more likely to receive results before surgery than to not be tested. CONCLUSIONS: This study highlights the role of patient-physician communication about GT as well as patient-level factors that predict presurgical GT.

Effects of Social Support Source and Effectiveness on Stress Buffering After Stem Cell Transplant.

BACKGROUND: This study used the social support effectiveness framework to examine whether effective social support buffered the relationship between stressful life events and distress among hematopoietic stem cell transplant (HSCT) survivors and whether that buffering effect depended on the type of caregiver who provided it (partner versus non-partner caregivers). METHODS: A total of 275 HSCT survivors completed measures of the effectiveness of their caregiver's support-social support effectiveness (SSE)-distress, and stressful life events. Hierarchical linear regression was used to analyze a three-way interaction between stressful life events, caregiver SSE, and caregiver type on distress. RESULTS: After controlling for covariates, the three-way interaction of stressful life events, caregiver SSE, and caregiver type was significant (b = - 0.21, SE = 0.00, p < 0.001). Among partnered survivors, more stressful life events were associated with greater distress (B = 0.03, SE = 0.01, p = 0.045) when caregiver SSE was low. There was no association between stressful life events and distress when caregiver SSE was average (B = 0.01, SE = 0.01, p = 0.50) or high (B = - 0.01, SE = 0.02, p = 0.61). Among non-partnered survivors, there was a positive association between stressful life events and distress regardless of caregiver SSE. CONCLUSIONS: Average or highly effective caregiver support buffered effects of stressful life events on distress among partnered survivors. There was no evidence that support at any level of effectiveness buffered stressful life events among non-partnered survivors. Findings highlight the importance of measuring social support effectiveness and source of support among HSCT survivors.

A mixed methods analysis of perceived cognitive impairment in hematopoietic stem cell transplant survivors.

OBJECTIVE: Hematopoietic stem cell transplant (HSCT) survivors may show evidence of objective cognitive impairment; however, perceived cognitive problems and their impact on quality of life are less well-understood. The purpose of this study was to explore HSCT survivors' perceptions of cognitive impairment and its effect on daily life functioning. METHOD: Sixty-nine autologous and allogeneic HSCT survivors nine months to three years posttransplant experiencing mild survivorship problems completed a brief structured interview regarding perceived cognitive impairment since transplant. Data were coded and content analyzed. The frequency of participants reporting cognitive problems by domain and associations between reports of cognitive problems and age, depressed mood, anxiety, and health-related quality of life were examined. RESULT: Overall, 49 of the 69 participants (71%) reported cognitive impairments after transplant: 38 in memory (55%), 29 in attention and concentration (42%), and smaller numbers in other domains. There were no significant differences in problems reported by transplant type. Of the 50 participants who worked before transplant, 19 (38%) did not return to work following transplant, with 12 citing cognitive and health problems as being the reason. There were significant associations between reports of cognitive impairment and younger age (p = 0.02), depressed mood (p = 0.02), anxiety (p = 0.002), and health-related quality of life (p = 0.008). SIGNIFICANCE OF RESULTS: A large proportion of survivors reported cognitive impairment following HSCT that impaired daily life functioning. Perceived cognitive impairment was associated with younger age, greater distress and reduced health-related quality of life.

Randomized trial of proactive rapid genetic counseling versus usual care for newly diagnosed breast cancer patients.

PURPOSE: Breast cancer patients who carry BRCA1/BRCA2 gene mutations may consider bilateral mastectomy. Having bilateral mastectomy at the time of diagnosis not only reduces risk of a contralateral breast cancer, but can eliminate the need for radiation therapy and yield improved reconstruction options. However, most patients do not receive genetic counseling or testing at the time of their diagnosis. In this trial, we tested proactive rapid genetic counseling and testing (RGCT) in newly diagnosed breast cancer patients in order to facilitate pre-surgical genetic counseling and testing. METHODS: We recruited newly diagnosed breast cancer patients at increased risk for carrying a BRCA1/2 mutation. Of 379 eligible patients who completed a baseline survey, 330 agreed to randomization in a 2:1 ratio to RGCT (n = 220) versus UC (n = 108). Primary outcomes were genetic counseling and testing uptake and breast cancer surgical decisions. RESULTS: RGCT led to higher overall (83.8% vs. 54.6%; p < 0.0001) and pre-surgical (57.8% vs. 38.7%; p = 0.001) genetic counseling uptake compared to UC. Despite higher rates of genetic counseling, RGCT did not differ from UC in overall (54.1% vs. 49.1%, p > 0.10) or pre-surgical (30.6% vs. 27.4%, p > 0.10) receipt of genetic test results nor did they differ in uptake of bilateral mastectomy (26.6% vs. 21.8%, p > 0.10). CONCLUSIONS: Although RGCT yielded increased genetic counseling participation, this did not result in increased rates of pre-surgical genetic testing or impact surgical decisions. These data suggest that those patients most likely to opt for genetic testing at the time of diagnosis are being effectively identified by their surgeons.

Light therapy as a treatment of cancer-related fatigue in (non-)Hodgkin lymphoma survivors (SPARKLE trial): study protocol of a multicenter randomized controlled trial.

BACKGROUND: Cancer related fatigue (CRF) is one of the most prevalent and distressing long-term complaints reported by (non-) Hodgkin survivors. To date there has been no standard treatment for CRF in this population. A novel and promising approach to treat CRF is exposure to bright white light therapy. Yet, large scale randomized controlled trials testing its efficacy in these patients and research on potential mechanisms is lacking. The objective of the current study is to investigate the efficacy of light therapy as a treatment for CRF and to explore potential mechanisms. METHODS/DESIGN: In a multicenter, randomized controlled trial we are evaluating the efficacy of two intensities of light therapy in reducing CRF complaints and restrictions caused by CRF in survivors of Hodgkin lymphoma or diffuse large B-cell lymphoma. Secondary outcomes include sleep quality, depression, anxiety, quality of life, cognitive complaints, cancer worries, fatigue catastrophizing, self-efficacy to handle fatigue, biological circadian rhythms of melatonin, cortisol and activity, and biomarkers of inflammation. We will recruit 128 survivors, with fatigue complaints, from academic and general hospitals. Survivors are randomized to either an intervention (exposure to bright white light) or a comparison group (exposure to dim white light). The longitudinal design includes four measurement points at baseline (T0), post-intervention at 3.5 weeks (T1), 3 months post-intervention (T2) and 9 months post-intervention (T3). Each measurement point includes self-reported questionnaires and actigraphy (10 days). T0 and T1 measurements also include collection of blood and saliva samples. DISCUSSION: Light therapy has the potential to be an effective treatment for CRF in cancer survivors. This study will provide insights on its efficacy and potential mechanisms. If proven to be effective, light therapy will provide an easy to deliver, low-cost and low-burden intervention, introducing a new era in the treatment of CRF. TRIAL REGISTRATION: The study is registered at ClinicalTrials.gov on August 8th 2017( NCT03242902 ).

Thinking about one's own death after prostate-cancer diagnosis.

BACKGROUND: Prostate-cancer diagnosis increases the risk for psychiatric morbidity and suicide. Thoughts about one's own death could indicate need for psychiatric care among men with localized prostate cancer. We studied the prevalence and predictors of thoughts about own death among men with prostate cancer. METHODS: Of the 3930 men in the prospective, multi-centre LAPPRO-trial, having radical prostatectomy, 3154 (80%) answered two study-specific questionnaires, before and three months after surgery. Multivariable prognostic models were built with stepwise regression and Bayesian Model Averaging. RESULTS: After surgery 46% had thoughts about their own death. Extra-prostatic tumor-growth [Adjusted Odds-Ratio 2.06, 95% Confidence Interval 1.66-2.56], university education [OR 1.66, CI 1.35-2.05], uncertainty [OR 2.20, CI 1.73-2.82], low control [OR 2.21, CI 1.68-2.91], loneliness [OR 1.75, CI 1.30-2.35], being a burden [OR 1.59, CI 1.23-2.07], and crying [OR 1.55, CI 1.23-1.96] before surgery predicted thoughts about one's own death after surgery. CONCLUSIONS: We identified predictors for thoughts about one's own death after prostate cancer diagnosis and surgery. These factors may facilitate the identification of psychiatric morbidity and those who might benefit from psychosocial support already during primary treatment.

Care-related predictors for negative intrusive thoughts after prostate cancer diagnosis-data from the prospective LAPPRO trial.

OBJECTIVE: Negative intrusive thoughts about one's prostate cancer have been associated with depressive mood and impaired quality of life among prostate cancer patients. However, little is known about possible predictors for negative intrusive thoughts among this group. We aimed to identify health- and care-related predictors for such thoughts among a population of men newly diagnosed with prostate cancer and undergoing radical prostatectomy. METHODS: In the LAPPRO-trial, 3154 men (80%) answered study-specific questionnaires at admission and 3 months after surgery. Questions concerned socio-demographics, health, uncertainty, preparedness for symptoms, and the outcome-negative intrusive thoughts. Associations between variables were analyzed by log-binominal and multivariable approach. RESULTS: The strongest predictor of negative intrusive thoughts at admission to surgery was uncertainty of cure, followed by binge drinking, poor physical health, antidepressant medication, not being prepared for urinary symptoms, age under 55, and physical pain. Reporting it not probable to obtain urinary symptoms after surgery lowered the odds. Negative intrusive thoughts before surgery were the strongest predictor for such thoughts 3 months later followed by uncertainty of cure, physical pain, younger age, living alone, and poor self-reported physical health. CONCLUSIONS: Our findings showed an association of preoperative uncertainty of cure as well as low preparedness for well-known surgery-induced symptoms with higher occurrence of negative intrusive thoughts about prostate cancer. Future studies should examine if interventions designed to have healthcare professionals inform patients about their upcoming prostatectomy reduce patients' negative intrusive thoughts and thereby, improve their psychological well-being.

Helping Yourself by Offering Help: Mediators of Expressive Helping in Survivors of Hematopoietic Stem Cell Transplant.

BACKGROUND: A randomized experiment by Rini et al. (Health Psychol. 33(12):1541-1551, 2014) demonstrated that expressive helping, which involves three expressive writing sessions regarding hematopoietic stem cell transplant, followed by one writing session directed toward helping other stem cell transplant recipients, reduced psychological distress and bothersome physical symptoms among stem cell transplant recipients with elevated survivorship problems, relative to a neutral writing control condition. PURPOSE: The current study evaluated whether word use reflective of emotional expression, cognitive processing, and change in perspective mediates the effects of expressive helping. METHOD: The essays of 67 stem cell transplant recipients with high survivorship problems were analyzed with Linguistic Inquiry and Word Count. Multiple mediation modeling was used to test the hypothesized mechanisms of expressive helping on distress and bothersome physical symptoms. RESULTS: Relative to the control condition, expressive helping produced significant reductions in psychological distress and marginal reductions in physical symptom bother in the analyzed subset of participants from the parent study. Results indicated that positive emotion word use significantly mediated effects of expressive helping on reduced distress, but only for participants who used average (compared to above or below average) rates of negative emotion words. Cognitive processing and change in perspective did not significantly mediate benefits of expressive helping. CONCLUSIONS: Expressive helping carried its positive effects on distress through participants' higher expression of positive emotions when coupled with moderate rates of negative emotions. Findings highlight the benefit of expressing both positive and negative emotions in stressful situations.

Cumulative risk over the early life course and its relation to academic achievement in childhood and early adolescence.

Early-life risk factors, such as family disruption, maltreatment, and poverty, can negatively impact children's scholastic abilities; however, most previous studies have relied on cross-sectional designs and retrospective measurement. This study investigated the relation between cumulative risk factors during the early life course and subsequent academic achievement in a cohort of children and adolescents. Data for this study were based on registry-data material from the LIFECOURSE study of 1151 children from the 2000 birth cohort in Reykjavik, Iceland, assembled in 2014-2016. Multiple lifetime risk factors, including maternal smoking during pregnancy, parent's disability status, being born to a young mother, number of children in the household, family income, number of visits to school nurses, and reports of maltreatment, were assessed. Latent class analysis and Analysis of Covariance (ANCOVA) were used to predict academic achievement in the 4th and 7th grades. Individuals with no risk factors reported the highest average academic achievement in the 4th (M=66 points, SD=17) and 7th grades (M=67 points, SD=15). There was a significant main effect for 4th-grade risk factors and academic achievement (F [7, 1146]=12.06, p<0.001) and a similar relationship between the risk factor profile and achievement scores in 7th grade (F [7, 1146]=15.08, p<0.001). Each additional risk factor was associated with a drop in academic achievement at both grade levels. We conclude that academic achievement declines in proportion to the number of risk factors in early life.

Personal resilience resources predict post-stem cell transplant cancer survivors' psychological outcomes through reductions in depressive symptoms and meaning-making.

This longitudinal study examined whether post-transplant cancer survivors (N = 254, 9 months to 3 years after stem cell transplant treatment) with greater personal resilience resources demonstrated better psychological outcomes and whether this could be attributed to reductions in depressive symptoms and/or four meaning-making processes (searching for and finding reasons for one's illness; searching for and finding benefit from illness). Hierarchical linear regression analyses examined associations of survivors' baseline personal resilience resources (composite variable of self-esteem, mastery, and optimism), which occurred an average of 1.7 years after transplant, and 4-month changes in psychological outcomes highly relevant to recovering from this difficult and potentially traumatic treatment: post-traumatic stress disorder (PTSD) symptoms and purpose in life. Boot-strapped analyses tested mediation. Greater personal resilience resources predicted decreases in PTSD stress symptoms (b = -0.07, p = 0.005), mediated by reductions in depressive symptoms (b = -0.01, 95% CI: -0.027, -0.003) and in searching for a reason for one's illness (b = -0.01, 95% CI: -0.034, -0.0003). In addition, greater resilience resources predicted increases in purpose in life (b = 0.10, p < 0.001), mediated by reductions in depressive symptoms (b = 0.02, 95% CI: 0.003, 0.033). Having greater personal resilience resources may promote better psychological adjustment after a difficult cancer treatment, largely because of improvements in depressive symptoms, although decreased use of a potentially maladaptive form of meaning-making (searching for a reason for one's illness) was also important for reducing PTSD symptoms.
