Emotion-related impulsivity across transdiagnostic dimensions of psychopathology.

OBJECTIVE: Several dimensions have received attention for their potential role in explaining shared variance in transdiagnostic symptoms of psychopathology. We hypothesized emotion-related impulsivity, the trait-like tendency toward difficulty restraining responses to emotion, would relate to symptoms of psychopathology, with two separable dimensions of emotion-related impulsivity relating distinctly to internalizing and externalizing symptoms. METHOD: Across two studies, we tested hypotheses using structural equation models of emotion-related impulsivity and multiple indicators of internalizing, externalizing, and thought symptoms. RESULTS: In Study 1 (658 undergraduates), emotion-related impulsivity was highly correlated with the general psychopathology (p) factor. In study 2 (421 Mechanical Turk participants), models did not support a general p factor; however, we replicated the hypothesized associations of emotion-related impulsivity dimensions with internalizing and externalizing factors. Across both studies, forms of emotion-related impulsivity uniquely and differentially related to internalizing and externalizing symptoms. CONCLUSIONS: Findings indicate emotion-related impulsivity may help explain transdiagnostic dimensions of psychopathology, such as the p factor.

Dyadic sleep intervention for adult patients with cancer and their sleep-partner caregivers: A feasibility study.

OBJECTIVES: Sleep disturbances are common among adult patients with cancer and their caregivers. To our knowledge, no sleep intervention to date has been designed to be provided to both patients with cancer and their caregivers simultaneously. This single-arm study aimed to pilot test the feasibility and acceptability, and to illustrate the preliminary efficacy on sleep efficiency of the newly developed dyadic sleep intervention, My Sleep Our Sleep (MSOS: NCT04712604). METHODS: Adult patients who were newly diagnosed with a gastrointestinal (GI) cancer and their sleep-partner caregivers (n = 20 persons: 10 dyads, 64 years old, 60% female patients, 20% Hispanic, 28 years relationship duration), both of whom had at least mild levels of sleep disturbance (Pittsburgh Sleep Quality Index [PSQI] ≥ 5) participated in this study. MSOS intervention consists of four 1-hour weekly sessions delivered using Zoom to the patient-caregiver dyad together. RESULTS: We were able to enroll 92.9% of the eligible and screened patient-caregiver dyads within 4 months. Participants reported high satisfaction in 8 domains (average 4.76 on a 1-5 rating). All participants agreed that the number of sessions, interval (weekly), and delivery mode (Zoom) were optimal. Participants also preferred attending the intervention with their partners. Both patients and caregivers showed improvement in sleep efficiency after completing the MSOS intervention: Cohen's d = 1.04 and 1.47, respectively. SIGNIFICANCE OF RESULTS: Results support the feasibility and acceptability, as well as provide the preliminary efficacy of MSOS for adult patients with GI cancer and their sleep-partner caregivers. Findings suggest the need for more rigorous controlled trial designs for further efficacy testing of MSOS intervention.

A Lens on Caregiver Stress in Cancer: Longitudinal Investigation of Cancer-Related Stress and Telomere Length Among Family Caregivers of Adult Patients With Cancer.

OBJECTIVE: Family members are typically the primary caregivers of patients with chronic illnesses. Family caregivers of adult relatives with cancer are a fast-growing population, yet the physical consequences of their stress due to the cancer in the family have been poorly understood. This study examined the bidirectional relations of the perceived stress of family caregivers of individuals recently diagnosed with cancer and leukocyte cellular aging indexed by telomere length for 2 years. METHODS: Family caregivers ( N = 168; mean age = 51 years, 70% female, 46% Hispanic, 36% spouse to the patient) of patients with colorectal cancer provided psychological data and peripheral blood samples approximately 4 (T1), 12 (T2), and 21 months (T3) after diagnosis. Time-lagged cross-panel modeling was used to test the associations of perceived cancer-related stress and telomere length, controlling for age, sex, and body mass index. RESULTS: Cancer-related stress was highest at T1 and decreased by 1 year. Greater cancer-related stress predicted longer telomere length at subsequent assessments for 2 years ( ß ≥ 0.911, p ≤ .019). However, telomere length did not change significantly for 2 years overall and did not prospectively predict cancer-related stress over this period. CONCLUSIONS: Findings suggest the need to better understand how the perceived stress of colorectal cancer caregivers, which tends to be intense for a relatively short period compared with dementia caregiving, may impact immune cell distributions and telomere length. These findings emphasize the need for further knowledge about psychobiological mechanisms of how cancer caregiving may impact cellular aging.

International collaboration for assessing unmet needs of cancer survivors and family caregivers: Lens of healthcare professionals.

OBJECTIVE: Cancer patients and their family caregivers have reported various needs that are not met. Recognition of the unmet needs by healthcare professionals may be a first step to adequately and systematically addressing them. Thus, the International Psycho-Oncology Society Survivorship Online Survey was developed to measure healthcare professionals' evaluation about the unmet needs of their patients and family caregivers around the globe. METHODS: The survey was developed in English and translated to additional 14 different languages. The survey was distributed on the web-based REDCap application to over 50 psycho-oncology societies and their networking platforms as well as social media and to authors who have published in psycho-oncology journals globally. RESULTS: A total of 1472 participants from 36 countries at least partially completed the survey. Healthcare professionals evaluated needs for managing one's emotional distress and patients' medical care and symptoms as the most common concerns for both patients and their family caregivers across all patient age groups. Less than two-thirds of the participating healthcare professionals reported that their institution had services or programs to address the needs of the patients or caregivers. CONCLUSIONS: Findings suggest several directions for further analyses to provide more specific information that would be readily translated into clinical practices, research, and policy aimed to enhance the quality of life of cancer patients, survivors, and family caregivers around the globe. In addition, this collaborative effort also hints at the importance of establishing international networks to promote equity in care for people touched by cancer worldwide.

The impact of integrating emotion focused components into psychological therapy: A randomized controlled trial.

OBJECTIVES: This paper presents a randomized controlled trial on assimilative integration, which is aimed at integrating elements from other orientations within one approach to enrich its conceptual and practical repertoire. Elements from Emotion-Focused Therapy (EFT) were integrated into a form of cognitive behavior therapy: Psychological Therapy (PT). In one treatment condition, EFT was added to PT (+EFT) with the intent to enhance therapists' working with emotions. In the other condition, concepts and interventions based on the socialpsychological self-regulation approach were added to PT (+SR). Our assumption was that the +EFT would lead to greater and deeper change, particularly in the follow-up assessments. METHOD: Patients (n = 104) with anxiety, depression, or adjustment disorders were randomized to the two conditions and treated by 38 therapists who self-selected between the conditions. Primary outcome was symptom severity at 12-month follow-up; secondary outcomes included several measures such as interpersonal problems and quality of life. Variables were assessed at baseline, after 8 and 16 sessions, at posttreatment, and at 6- and 12-month follow-up. RESULTS: Contrary to our hypothesis, no significant between-group effects were found. CONCLUSION: The findings first suggest the difficulty of topping an already very effective approach to psychotherapy. Alternative interpretations were that the EFT training, while corresponding to regular practice in AI, was not sufficient to make a difference in outcome, or that while profiting from the enhancement of abilities for working with emotions, this was outbalanced by negative effects of difficulties related to the implementation of the new elements.

Marital Status and Gender Associated with Sleep Health among Hispanics/Latinos in the US: Results from HCHS/SOL and Sueño Ancillary Studies.

Poor sleep and different patterns of marital status among Hispanics/Latinos have been documented, yet the extent to which marital status is associated with sleep health and the moderating role of gender in this association among Hispanics/Latinos is poorly understood.Demographic and sleep data were obtained from the Hispanic Community Health Study/Study of Latinos (HCHS/SOL: n= 16,415), an epidemiological cohort study, and the Sueño Study (n= 2,252) that is an ancillary to HCHS/SOL. Sleep duration, insomnia symptoms, daytime sleepiness, napping, and snoring were self-reported and drawn from HCHS/SOL. Sleep efficiency, sleep fragmentation, and inter-day stability were objectively assessed in the Sueño Study.Complex sample analyses indicated that being married or cohabiting was associated with better sleep health in general, including having normal sleep duration, fewer insomnia symptoms, and higher sleep efficiency (F> 2.804, p< .044). These associations were more prominent in objectively measured sleep indices and among females.Findings suggest being in a committed relationship associated with better sleep health in Hispanics/Latinos in the US, a diverse and under-represented population. Findings may have implications for tailoring sleep health interventions to at-risk populations who may less likely to be in a committed relationship.

Only the Lonely: Expression of Proinflammatory Genes Through Family Cancer Caregiving Experiences.

OBJECTIVE: The experience of cancer elicits not only turmoil but also resilience in the family, which has been related to psychological adjustment and physical health of family caregivers. The biological pathways linking family cancer caregiving to health, however, remain poorly understood. This study examined the extent to which psychological risk and resilience factors related to a proinflammatory gene expression profile (conserved transcriptional response to adversity, or CTRA) among caregivers during the first-year postdiagnosis of a patient with colorectal cancer. METHODS: A total of 41 caregivers (mean age = 54 years, 74% female, 40% Hispanic) provided psychological data and peripheral blood samples around 4 and 12 months after diagnosis. Mixed regression models controlling for demographic and biometric factors were used to test the associations of caregiver CTRA gene expression with caregiving stress, loneliness, and lack of social support (risk factors), as well as benefit finding and meaning (resilience factors). RESULTS: When individually tested, all but benefit finding were significantly related to CTRA (R2 ≥ 0.112, p < .045). When adjusted for other factors in either the risk or resilience group, loneliness, social support, and meaning effects remained significant (R2 ≥ 0.120, p < .041). When all study factors were simultaneously adjusted (R2 = 0.139), only loneliness remained significant (p = .034). CONCLUSIONS: Findings suggest that caregiving-related transcriptional effects seem to be most pronounced when caregivers experience low social support and loneliness, as well as little meaning or purpose in their caregiving. These findings suggest that the development of new intervention strategies that prioritize reductions in caregiver loneliness may favorably impact biological mechanisms related to caregiver health.

A multi-method examination of the link between obsessive-compulsive symptomatology and emotion-related impulsivity.

OBJECTIVES: Obsessive-compulsive disorder (OCD) is a condition marked by recurrent and distressing thoughts, images, and urges accompanied by repetitive physical or mental rituals. An emerging line of work suggests that emotion may be an important consideration when looking at the role of impulsivity across the spectrum of psychopathology, including OCD. The current study examined the relationship between obsessive-compulsive symptomatology (OCS) and impulsive cognitive and behavioural reactions to emotion using a multi-study, multi-method approach. DESIGN: Data were collected cross-sectionally online (Study 1) or via an in-person laboratory visit (Study 2). METHODS: In Study 1, self-report measures of impulsivity and OCS were administered to a large, non-selected community sample (N = 386). Study 2 extended these findings with a young adult sample (N = 107) with clinically elevated OCS using self-report measures, clinical interview, and two behavioural symptom provocation tasks. RESULTS: Emotion-related impulsivity, but not non-emotion-related impulsivity, was associated with greater severity of OCS across symptom domains and across all modes of assessment. Impulsive cognitive responses to emotion were associated with greater obsession severity, while impulsive behavioural reactions to emotion were associated with greater compulsions. Emotion-related impulsivity also acted synergistically with a belief in the importance and control of thoughts, such that this established risk factor for OCD was associated with greater OCS severity only when behavioural reactivity to emotion was also present. CONCLUSIONS: Results highlight the importance of considering emotional context when studying impulsivity in OCD, and point to the potentially differential relationship between OCS and behavioural versus cognitive impulsive reactions to emotion. PRACTITIONER POINTS: Emotion-related impulsivity (ERI) reflects a tendency to act impulsively in the context of strong emotions. ERI was associated with greater OCS across symptom domains and type of symptom assessment (self-report, interview, or symptom provocation). ERI also interacted with an established OCS risk factor, a belief in the importance and control of thoughts, to predict symptom severity, suggesting that it may be important to evaluate and address ERI alongside unhelpful beliefs in patients with OCS. Given the present study's cross-sectional nature, we cannot draw conclusions about the directionality of the ERI - OCS relationship, and while our study included individuals with clinically elevated OCS, results should be replicated in a fully clinical sample.

Passages of cancer caregivers' unmet needs across 8 years.

BACKGROUND: Identifying and addressing caregivers' unmet needs have been suggested as a way of reducing their distress and improving their quality of life. However, the needs of family cancer caregivers are complex in the period of long-term survivorship in particular because they may diverge as the patients' survivorship trajectory does, and that is what this study investigated. METHODS: Family cancer caregivers completed prospective, longitudinal surveys 2, 5, and 8 years after diagnosis (n = 633). Early caregiving characteristics and demographics were measured at 2 years. Caregiver status (former caregivers-remission, current caregivers, and bereaved caregivers) and unmet needs were measured at 3 assessments. RESULTS: Caregivers' unmet needs at 8 years were attributable to the passages of the caregiving status as their patients' illness trajectory diverged from the initial state of receiving care. Specifically, either prolonged caregiving or having a break from caregiving followed by bereavement during long-term survivorship was related to various domains of unmet needs at 8 years (t > 2.35, P < .02). Early perceived caregiving stress also predicted all domains of unmet needs at 8 years (t > 2.50, P < .02). Unmet needs at 8 years were the highest across the 3 assessment time points (F > 37.51, P < .001). CONCLUSIONS: The caregiving status trajectory over 8 years was a substantial predictor of family caregivers' unmet needs at the 8-year mark. Findings provide guidance for the development of evidence-based programs and patient/caregiver-centered care policies to reduce the unmet needs of family caregivers, which reflect the diverse trajectories of cancer caregivership, many years after the diagnosis of their patients.

Fear of cancer recurrence promotes cancer screening behaviors among family caregivers of cancer survivors.

BACKGROUND: Fear of cancer recurrence (FCR) has been associated with cancer screening behaviors among cancer survivors, but to the authors' knowledge, the question of whether the same is true for caregivers is unknown. The current study investigated the extent to which FCR among caregivers predicted their cancer screening behaviors years after their relatives' cancer diagnosis. METHODS: A total of 813 caregivers (67% of whom were female, mean age of 56 years, and 92% non-Hispanic white) completed surveys 2 years (T1) and 8 years (T2) after their patients' cancer diagnosis. FCR, anxiety (Profile of Mood States-Short Form [POMS-SF]), and general mental health (Medical Outcomes Study 36-Item Short-Form Health Survey [MOS SF-36]) were reported at T1; caregivers' engagement in screening for colorectal, breast, and prostate cancers because of the patients' diagnoses were reported at T2. RESULTS: Caregivers were found to engage in cancer screening at rates similar to those of the national average. Controlling for covariates, hierarchical logistic regression modeling for each type of cancer screening demonstrated that greater FCR was linearly related to a higher likelihood of undergoing colorectal cancer screening (odds ratio [OR], 1.15) and maintaining prostate cancer screening (OR, 1.34), but a lower likelihood of maintaining breast cancer screening in an age-appropriate manner (OR, 0.27). Examining curvilinear effects demonstrated that moderate levels of FCR were associated with a higher likelihood of maintaining age-appropriate colorectal cancer screening (OR, 1.48). CONCLUSIONS: The overall FCR among caregivers uniquely promotes their engagement in cancer screening behaviors. The role of caregivers' FCR in other types of cancer preventive behaviors and ways to channel FCR concerns into promoting healthy lifestyle behaviors should be investigated.

Bereaved Family Cancer Caregivers' Unmet Needs: Measure Development and Validation.

PURPOSE/BACKGROUND: Accumulating evidence shows that bereaved family caregivers report elevated distress for an extended period, which compromises their quality of life. A first step in the development of programs to enhance bereaved caregivers' quality of life should be determining the needs they experience to manage the loss, and the needs that are not being satisfied. Thus, this study aimed to develop a new measure to assess unmet needs among bereaved family caregivers. METHOD: The 20-item Needs Assessment of Family Caregivers-Bereaved to Cancer measure was developed and validated with bereaved cancer caregivers 5 (n = 159) and 8 (n = 194) years after the initial cancer diagnosis of the index patient, when stress in providing care to the patient was assessed. RESULTS: Exploratory factor analysis yielded two primary factors: unmet needs for reintegration and unmet needs for managing the loss. Bereaved caregivers who were younger and ethnic minority, and who had greater earlier perceived stress of caregiving, reported their needs were more poorly met (t > 2.33, p < .05). The extent to which bereaved caregivers' needs to manage the loss were not perceived as being met was a consistent and strong predictor of poor adjustment to bereavement at both 5- and 8-year marks (t > 1.96, p < .05), beyond the effects of a host of demographic and earlier caregiving characteristics. CONCLUSION: Findings support the validity of the Needs Assessment of Family Caregivers-Bereaved to Cancer and suggest that interventions to help bereaved caregivers manage the loss by assisting their transition to re-engagement in daily and social activities will benefit caregivers by mitigating bereavement-related distress years after the loss.

Identity in bipolar disorder: Self-worth and achievement.

This article considers self and self-concept in bipolar disorder. Bipolar disorder, defined on the basis of manic symptoms, is a highly debilitating psychopathology. It is heavily grounded in biology but symptom course is still very responsive to psychological and social forces in the lives of persons who have the disorder. This review assumes an overall view of the self that is typical of personality psychology: self as traits, self as goals and aspirations, and ongoing efforts to attain those goals. In this review, we will discuss two different facets of self and identity in bipolar disorder. First, we review a body of goal pursuit literature suggesting that persons with bipolar disorder endorse heightened ambitions for attaining goals and recognition from others. Second, we will review multiple findings which suggest that among persons with bipolar disorder, self-worth depends on measurable success in an extreme way. We will consider how the intersection of these two themes may lead to unique identity challenges for people with bipolar disorder, drawing from self-report, behavioral, and neuroscience findings to critically examine this viewpoint.

Social comparisons predict health-related quality of life and depressive symptoms across the first year of breast cancer treatment.

BACKGROUND: Social comparisons (SCs) are common among cancer patients, but their prospective associations are not well understood. This study examined concurrent and prospective relationships of SCs with health-related quality of life (HRQOL) and depressive symptoms during the first year of breast cancer treatment. METHODS: Nonmetastatic breast cancer patients (N = 240) enrolled in a larger intervention trial reported on the frequencies of SCs postsurgery (T1) and 6 months later (T2). HRQOL and depressive symptoms were assessed at T1, T2, and 12 months after T1 (T3). Path analysis via structural equation modeling was used to assess three models relating SCs to HRQOL and depressive symptoms from T1-T2, T1-T3, and T2-T3, controlling for stage of disease, intervention condition, and dispositional optimism. RESULTS: Upward contrast SCs were associated with poorer concurrent HRQOL at T1 and T2, and with more concurrent depressive symptoms at T2. However, upward contrast SC at T1 predicted better T2 and T3 HRQOL. Upward identification SC at T1 predicted more T2 depressive symptoms, and at T2 was associated with poorer concurrent HRQOL and more concurrent depressive symptoms. Downward identification SCs at T1 were associated with poorer concurrent HRQOL. Downward identification SCs at T2 predicted poorer T3 HRQOL. CONCLUSIONS: Upward SCs were related to compromised concurrent psychosocial well-being, but prospective effects varied by the interpretation of the comparison (ie, contrast vs identification). Findings have implications for the development and deployment of group-based psychosocial interventions during the early phases of survivorship, during which opportunities for SC are prevalent.

Preloss Spirituality Predicts Postloss Distress of Bereaved Cancer Caregivers.

Background: Although spirituality has been identified as a psychological resource relevant to coping with caregiving stress, little is known about the differential roles of spirituality's facets in bereaved caregivers' adjustment. Purpose: This study examined this question with regard to bereavement-specific and general distress in cancer caregivers. Methods: Cancer caregivers provided data at 2 years after their relative's diagnosis when all the patients were alive (Time 1, preloss) and 3 years later, after the patient had died (Time 2, postloss: N = 128). Demographics and three facets of spirituality (meaning, peace, and faith) were measured at Time 1. Psychological distress and time since the death were measured at Time 2. Results: Younger age, less education, and being a spousal caregiver of the patient related to greater bereavement-specific and general distress (ts ≥ 2.02, ps < .05, partial η2 ≥ .15). Above and beyond these demographic factors, two preloss spirituality facets related to postloss distress. Specifically, a greater sense of inner peace at preloss was prospectively associated with less bereavement-specific distress (both intrusive thoughts and hyperarousal, ts ≥ 2.24, ps < .05, partial η2 ≥ .41). Greater reliance on faith at preloss was also prospectively associated with lower intrusive thoughts (t = 2.24, p < .05, partial η2 = .34). Conclusion: Findings highlight the importance of preloss sense of peace as a predictor of psychological distress during bereavement. Programs and interventions might be designed to help caregivers find inner peace while caregiving, in an effort to augment their resiliency against psychological distress when facing the loss of the patient.

Serotonin transporter polymorphism, depressive symptoms, and emotional impulsivity among advanced breast cancer patients.

PURPOSE: This study tested a theory linking a marker of low serotonergic function to both depression and impulsivity in a sample of advanced breast cancer patients, among whom elevated depressive symptoms and difficulty regulating emotions are commonly reported. METHODS: A total of 95 patients provided blood samples for serotonin transporter polymorphic region of the gene (5-HTTLPR) and completed questionnaires that measured depressive symptoms and emotional impulsivity. RESULTS: Structural equation modeling revealed that the s allele of 5-HTTLPR was related to greater depressive symptoms (ß = .20, p < .042) but only marginally to greater emotional impulsivity (ß = .19, p < .068). Depressive symptoms and emotional impulsivity were positively related (ß = .33, p < .003). Further tests explored possible mediation from genotype to one psychological variable via the other. Results suggest that depressive symptoms, particularly perceived interpersonal rejection, may be a pathway linking genotype to emotional impulsivity. CONCLUSIONS: Findings provide the first evidence that low serotonergic function contributes to both depression and impulsivity within a clinically meaningful sample. Furthermore, the link of s allele of 5-HTTLPR to emotional impulsivity was mediated by depressive symptoms, particularly perceptions of social rejection. Findings have implications for advanced breast cancer patients' treatment decision.

Depressive symptoms predict cancer caregivers' physical health decline.

BACKGROUND: Cancer caregiving has been associated with worsening health among caregivers themselves, yet demographic and psychosocial predictors of their long-term health decline are less known. This study examines changes in caregivers' physical health 2 to 8 years after their family members' cancer diagnosis and prospective predictors of that change. METHODS: Caregivers (n = 664; mean age, 53.2 years) participated in a nationwide study at 2 (T1), 5 (T2), and 8 (T3) years after their family members' cancer diagnosis. Physical health (12-item Medical Outcomes Study Short Form Health Survey Physical Component Scale) was assessed T1 through T3 as outcome. Predictors were self-reported at T1, including caregiver demographics (age, sex, education, income, relationship to patient, and employment status), patient cancer severity (from medical records), and caregiver psychosocial factors (caregiving stress, caregiving esteem, social support, and depressive symptoms). Latent growth modeling tested predictors of caregivers' initial physical health and their physical health change across time. RESULTS: At T1, caregivers reported slightly better physical health than the US population (M = 51.22, P = .002), which declined over the following 6 years (Mslope = -0.27, P < .001). All demographic factors, patient cancer severity, and T1 caregiving stress were related to caregivers' initial physical health (P ≤ .03). Higher depressive symptoms were unrelated to caregivers' initial physical health, but were the only significant predictor of caregivers' more rapid physical health decline (B = -0.02, P = .004). CONCLUSION: Findings highlight the unique contribution of caregivers' depressive symptoms to their physical health decline. Assessing and addressing depressive symptoms among caregivers early in the cancer survivorship trajectory may help to prevent premature health decline among this important yet vulnerable population.

Social well-being is associated with less pro-inflammatory and pro-metastatic leukocyte gene expression in women after surgery for breast cancer.

PURPOSE: Satisfaction with social resources, or "social well-being," relates to better adaptation and longer survival after breast cancer diagnosis. Biobehavioral mechanisms linking social well-being (SWB) to mental and physical health may involve inflammatory signaling. We tested whether reports of greater SWB were associated with lower levels of pro-inflammatory and pro-metastatic leukocyte gene expression after surgery for non-metastatic breast cancer. METHODS: Women (N = 50) diagnosed with non-metastatic (0-III) breast cancer were enrolled 2-8 weeks after surgery. SWB was assessed with the social/family well-being subscale of the FACT-B. Leukocyte gene expression for specific pro-inflammatory (cytokines, chemokines, and COX-2) and pro-metastatic genes (e.g., MMP9) was derived from microarray analysis. RESULTS: Multiple regression analyses controlling for age, stage of disease, days since surgery, education, and body mass index (BMI) found higher levels of SWB related to less leukocyte pro-inflammatory and pro-metastatic gene expression (p < 0.05). Emotional well-being, physical well-being, and functional well-being did not relate to leukocyte gene expression (p > 0.05). Greater SWB remained significantly associated with less leukocyte pro-inflammatory and pro-metastatic gene expression after controlling for depressive symptoms. CONCLUSIONS: Results have implications for understanding mechanisms linking social resources to health-relevant biological processes in breast cancer patients undergoing primary treatment.

Role of family caregivers' self-perceived preparedness for the death of the cancer patient in long-term adjustment to bereavement.

BACKGROUND: A substantial number of family caregivers go through bereavement because of cancer, but little is known about the bereaved caregivers' long-term adjustment. This study aimed to document levels of bereavement outcomes (prolonged grief symptoms, intense emotional reaction to the loss, depressive symptoms, and life satisfaction) among family cancer caregivers 3-5 years post-loss and to investigate how self-rated preparedness for the patient's death predicted those bereavement outcomes. METHODS: Family members participated in a nationwide survey for cancer caregivers 2 years after the relative's diagnosis (T1). Of those, 109 were identified as bereaved by 5 years post-diagnosis (T2). Of those, 88 continued to participate at 8-year follow-up (T3) and provided valid data for the study variables. Caregivers' distress risk factors were measured at T1, satisfaction with palliative care and preparedness for the death of the patient at T2, and time since death of the patient at T2 or T3. RESULTS: Substantial numbers of family members (18% to 48%) displayed heightened levels of bereavement-related psychological distress years after the loss. Hierarchical general linear modeling revealed that perceived preparedness for the death of the patient concurrently and prospectively predicted better adjustment to bereavement, independent of contributions of other factors studied. CONCLUSIONS: Findings underscore the high prevalence of long-lasting bereavement-related distress among family cancer caregivers and the role of preparedness for the relative's death in the level of that distress. Findings suggest that psychosocial programs among caregivers focus on not only caregiving skills per se but also preparedness for the death of the patient. Copyright © 2015 John Wiley & Sons, Ltd.

A path model of different forms of impulsivity with externalizing and internalizing psychopathology: Towards greater specificity.

OBJECTIVES: A growing empirical literature indicates that emotion-related impulsivity (compared to impulsivity that is unrelated to emotion) is particularly relevant for understanding a broad range of psychopathologies. Recent work, however, has differentiated two forms of emotion-related impulsivity: A factor termed Pervasive Influence of Feelings captures tendencies for emotions (mostly negative emotions) to quickly shape thoughts, and a factor termed Feelings Trigger Action captures tendencies for positive and negative emotions to quickly and reflexively shape behaviour and speech. This study used path modelling to consider links from emotion-related and non-emotion-related impulsivity to a broad range of psychopathologies. DESIGN AND METHODS: Undergraduates completed self-report measures of impulsivity, depression, anxiety, aggression, and substance use symptoms. RESULTS: A path model (N = 261) indicated specificity of these forms of impulsivity. Pervasive Influence of Feelings was related to anxiety and depression, whereas Feelings Trigger Action and non-emotion-related impulsivity were related to aggression and substance use. CONCLUSIONS: The findings of this study suggest that emotion-relevant impulsivity could be a potentially important treatment target for a set of psychopathologies. PRACTITIONER POINTS: Recent work has differentiated two forms of emotion-related impulsivity. This study tests a multivariate path model linking emotion-related and non-emotion-related impulsivity with multiple forms of psychopathology. Impulsive thoughts in response to negative emotions were related to anxiety and depression. Impulsive actions in response to emotions were related to aggression and substance use, as did non-emotion-related impulsivity. The study was limited by the reliance on self-report measures of impulsivity and psychopathology. There is a need for longitudinal work on how these forms of impulsivity predict the onset and course of psychopathology.

Postsurgical Depressive Symptoms and Proinflammatory Cytokine Elevations in Women Undergoing Primary Treatment for Breast Cancer.

OBJECTIVE: Depression and inflammation may independently promote breast cancer (BCa) disease progression and poorer clinical outcomes. Depression has been associated with increased levels of inflammatory markers in medically healthy individuals and patients with cancer. However, inconsistencies in study time frames complicate interpretation of results within specific cancer types. This study examined relationships between depressive symptoms and inflammation in women with early-stage BCa before beginning adjuvant treatment. METHODS: Women with Stage 0-III BCa were recruited approximately 4 to 8 weeks after surgery. Depressive symptoms were assessed using the Hamilton Rating Scale for Depression, and blood samples were collected to quantify circulating levels of interleukin (IL)-1ß, IL-6, and tumor necrosis factor α (TNF-α) by enzyme-linked immunosorbent assay. Analyses of covariance were used to test for group differences (elevated versus low depressive symptoms) in levels of cytokines. Multiple regression analyses were used to examine relationships between continuous severity of depressive symptoms and levels of cytokines adjusting for relevant biobehavioral covariates. RESULTS: Thirty-six (40%) of 89 patients showed elevated levels of depressive symptoms and, in adjusted models, had marginally higher levels of IL-1ß (mean [M] = 14.49 [95% confidence interval {CI} = 6.11-32.65] versus M = 4.68 [95% CI = 1.96-9.86] and IL-6 [M = 88.74 {95% CI = 33.28-233.96} versus M = 61.52 {95% CI = 27.44-136.40}]) significantly higher levels of TNF-α (M = 17.07 [95% CI = 8.27-34.32] versus M = 6.94 [95% CI = 3.58-12.80]) than did women with low depressive symptoms. Across the spectrum of depressive symptoms, greater magnitude of depressive symptoms was related to greater levels of IL-1ß (ß = 0.06, p = .006, R = 0.25) and TNF-α (ß = 0.06, p = .003, R = 0.27). CONCLUSIONS: Postsurgery and preadjuvant treatment for early-stage BCa, depressive symptoms covary with elevated levels of multiple proinflammatory cytokines. Findings have implications for psychosocial and biological interventions concurrently focusing on depression and inflammation. TRIAL REGISTRATION: NCT01422551.
