Attachment theory and group processes: The association between attachment style and group-related representations, goals, memories, and functioning.

Four studies examined attachment-style differences in group-related cognitions and behaviors. In Studies 1-2, participants completed scales on group-related cognitions and emotions. In Studies 3-4, participants were divided into small groups, and their performance in group tasks as well as the cohesion of their group were assessed. Both attachment anxiety and avoidance in close relationships were associated with negative group-related cognitions and emotions. Anxiety was also related to the pursuit of closeness goals and impaired instrumental performance in group tasks. Avoidance was related to the pursuit of distance goals and deficits in socioemotional and instrumental performance. Group cohesion significantly moderated the effects of attachment anxiety. The discussion emphasizes the relevance of attachment theory within group contexts. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Evaluation of problem solving and communication skills of persons with schizophrenia

This study examined gender differences in 162 female and 65 male patients with cancer referred to home care. Data were collected before hospital discharge using the Multidimensional Functional Assessment Questionnaire, the Karnofsky Performance Status, and the Quality of Life-Cancer Scale. Controlling for age and stage of disease, the results showed that men reported significantly more cancer-related impairments, more limitations in activity of daily living, and poorer social resources than women. No gender differences were found in quality of life, perceived emotional health, perceived physical health, performance status, and comorbidity. Significant predictors of self-care activities were: for women perceived physical health, Karnofsky Performance Status, and stage of disease (58% variance explained); for men Karnofsky Performance Status and medication taken (67% variance explained). Gender differences should be considered in discharge planning to provide appropriate home care services for male and female patients with cancer.     

Understanding the association between socioeconomic status and physical health: Do negative emotions play a role?

In this article, the authors evaluate the possible roles of negative emotions and cognitions in the association between socioeconomic status (SES) and physical health, focusing on the outcomes of cardiovascular diseases and all-cause mortality. After reviewing the limited direct evidence, the authors examine indirect evidence showing that (a) SES relates to the targeted health outcomes, (b) SES relates to negative emotions and cognitions, and (c) negative emotions and cognitions relate to the targeted health outcomes. The authors present a general framework for understanding the roles of cognitive-emotional factors, suggesting that low-SES environments are stressful and reduce individuals' reserve capacity to manage stress, thereby increasing vulnerability to negative emotions and cognitions. The article concludes with suggestions for future research to better evaluate the proposed model. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Negative social evaluation, but not mere social presence, elicits cortisol responses to a laboratory stressor task.

Background: Recent research has supported the premise that performance conditions characterized by social-evaluative threat, in which an aspect of the self could be judged by others, are associated with cortisol responses. However, it remains unclear whether this effect is due to negative social evaluation per se or simply the presence of another during a performance situation. Method: In the present study, 89 undergraduates delivered a speech in 1 of 3 conditions: in front of an evaluative audience panel (social-evaluative threat [SET]), in the presence of an inattentive confederate (PRES), or alone in a room (non-SET). Results: Consistent with hypotheses, participants in the SET condition demonstrated a significant cortisol response, while those in the non-SET and PRES conditions did not show increases in this hormone. Further, participants in the SET condition who reported greater posttask levels of self-conscious cognitions and emotions demonstrated the greatest increases in cortisol. Conclusion: These findings suggest that the mere social presence of others is not driving the changes in cortisol observed under social-evaluative threat; instead, explicit negative social evaluation may be responsible for increases in this health-relevant physiological parameter.

Healing the wounds of organizational injustice: Examining the benefits of expressive writing.

Clinical and health psychology research has shown that expressive writing interventions—expressing one's experience through writing—can have physical and psychological benefits for individuals dealing with traumatic experiences. In the present study, the authors examined whether these benefits generalize to experiences of workplace injustice. Participants (N = 100) were randomly assigned to write on 4 consecutive days about (a) their emotions, (b) their thoughts, (c) both their emotions and their thoughts surrounding an injustice, or (d) a trivial topic (control). Post-intervention, participants in the emotions and thoughts condition reported higher psychological well-being, fewer intentions to retaliate, and higher levels of personal resolution than did participants in the other conditions. Participants in the emotions and thoughts condition also reported less anger than did participants who wrote only about their emotions.

The efficacy of an implementation intention intervention for promoting physical activity among individuals with spinal cord injury: A randomized controlled trial.

Objective: To evaluate the efficacy of an 8-week implementation intention intervention for promoting physical activity among individuals with spinal cord injury. Study Design: Randomized clinical trial. Method: Participants were randomly assigned to an implementation intention intervention (n = 26) or control (n = 28) condition and were asked to engage in 30 min of moderate to heavy intensity physical activity 3 times per week. Results: Participants who formed implementation intentions followed through with their physical activity intentions, engaging in more physical activity than participants in the control condition. Participants in the intervention condition also experienced sustained motivation and greater confidence to schedule physical activity compared with participants in the control condition. Implications: These findings suggest a role for implementation intentions in health promotion programs for people with spinal cord injury.

Completion and subject loss within an intensive hepatitis vaccination intervention among homeless adults: The role of risk factors, demographics, and psychosocial variables.

Objective: Unprotected sexual behavior, needle sharing, and a prison history are major correlates of hepatitis B Virus (HBV). These risk factors are common among homeless people who also have elevated rates of HBV. We examine whether these behaviors were associated with completion or loss to follow-up of the most intensive and successful condition of a 3-arm HBV vaccination intervention. Significant results would imply that those most in need are the least compliant. Contributions of baseline demographics, physical health, psychosocial variables, and health beliefs were also assessed. Design: Three-hundred thirty- one adults from Los Angeles' Skid Row were assigned to nurse-case-managed sessions with hepatitis education, incentives, and tracking. Successive predictive structural equation models assessed the amount of variance accounted for by the risk variables, demographics, and the health-related variables. Main Outcome Measures: (1) Completion of 3 injections by 6 months; and (2) loss to a 6-month follow-up questionnaire. Results: The 3 risk factors explained 2% of the variance in completion and 1% of the variance in loss. Adding the other variables increased the variance explained to 14% for completion and 13% for loss. African American ethnicity, positive coping, social support, poorer health, no prison history, and greater efficacy significantly predicted completion. White ethnicity, less social support, better health, and less intention to complete predicted participant loss. Conclusion: The program was not strongly rejected differentially as a function of preexisting hepatitis B risk behaviors. Programs designed for homeless people should include malleable psychosocial and health belief model variables. These aspects of the lives of homeless people provide leverage points for future interventions. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Asking questions changes behavior: Mere measurement effects on frequency of blood donation.

Objective: This research examined the impact of completing a questionnaire about blood donation on subsequent donation behavior among a large sample of experienced blood donors. Design: Participants (N = 4672) were randomly assigned to an experimental condition that received a postal questionnaire measuring cognitions about donation or a control condition that did not receive a questionnaire. Main Outcome Measures: Number of registrations at blood drives and number of successful blood donations were assessed using objective records both 6 months and 12 months later. Results: Findings indicated that, compared to control participants, the mean frequency of number of registrations at blood drives among participants in the experimental group was 8.6% greater at 6 months (p     

Respiratory effort sensation during exercise with induced expiratory-flow limitation in healthy humans

Nine healthy subjects (age 31 +/- 4 yr) exercised with and without expiratory-flow limitation (maximal flow approximately 1 l/s). We monitored flow, end-tidal PCO2, esophageal (Pes) and gastric pressures, changes in end-expiratory lung volume, and perception (sensation) of difficulty in breathing. Subjects cycled at increasing intensity (+25 W/30 s) until symptom limitation. During the flow-limited run, exercise performance was limited in all subjects by maximum sensation. Sensation was equally determined by inspiratory and expiratory pressure changes. In both runs, 90% of the variance in sensation could be explained by the Pes swings (difference between peak inspiratory and peak expiratory Pes). End-tidal PCO2 did not explain any variance in sensation in the control run and added only 3% to the explained variance in the flow-limited run. We conclude that in healthy subjects, during normal as well as expiratory flow-limited exercise, the pleural pressure generation of the expiratory muscles is equally related to the perception of difficulty in breathing as that of the inspiratory muscles.     

Physical fitness, physical activity, and functional limitation in adults aged 40 and older

PURPOSE: A cohort of middle-aged and older men and women were followed for an average of 5.5 yr to examine the association between physical fitness, physical activity, and the prevalence of functional limitation. METHODS: The participants received medical assessments between 1980 and 1988 and responded to a mail-back survey regarding functional status in 1990. RESULTS: Among 3495 men and 1175 women over 40 yr of age at baseline, 350 (7.5%) reported at least one functional limitation in daily or household activities at follow-up. The prevalence of functional limitation was higher among women than men. Physically fit and physically active participants reported less functional limitation than unfit or sedentary participants. After controlling for age and other risk factors, the prevalence of functional limitation was lower for both moderately fit (odds ratio = 0.4, 95% CI = 0.2-0.6) and high fit men (odds ratio = 0.3, 95% CI = 0.2-0.4), compared with low fit men. Corresponding figures for women were 0.5 (0.3-0.7) and 0.3 (0.2-0.5) for moderately fit and high fit women. The association between physical activity and functional limitation was similar to the data for physical fitness. CONCLUSIONS: These data support a protective effect of physical fitness and physical activity on functional limitation among older adults and extend this protective effect to middle-aged men and women.     

Effects of depressive symptoms on health behavior practices among older adults with vision loss.

Objective: The authors examined the interface between visual impairment and depressive symptoms on health behaviors, self-care, and social participation among adults ages 65 and older. Method: The authors analyzed data from the 1997–2004 National Health Interview Survey on visual impairment and depressive symptoms for 49,278 adults ages 65 and older, comparing visually impaired adults (n = 8,787) with and without depressive symptoms with a reference group of adults with neither condition (n = 3,136) for outcome measures: physical health, health behaviors, and difficulties with self-care and social participation. Results: Adults with visual impairment and severe depressive symptoms were more likely than adults with neither condition to smoke (14.9%, adjusted odds ratio [AOR] = 1.6), be obese (28.2%, AOR = 1.9), be physically inactive (80.5%, AOR = 3.0), have fair–poor health (76.0%, AOR = 26.5), and have difficulties with self-care (27.9%, AOR = 11.8) and social participation (52.1%, AOR = 10.9). Discussion and Conclusions: Older visually impaired adults with depressive symptoms are vulnerable to health decline and further disablement without timely interventions that target smoking cessation, healthy eating, and increased physical activity.

Predicting walking intentions and exercise in individuals with intermittent claudication: An application of the theory of planned behavior.

Objective: To identify determinants of intention and walking activity among individuals with intermittent claudication using the theory of planned behavior. Study Design and Participants: Prospective, correlational study of men and women (n = 62) with intermittent claudication. Method: Baseline questionnaire assessing theory of planned behavior measures regarding walking. Telephone follow-up assessing frequency and duration of walking during the previous week. Results: Attitudes, subjective norms, and perceived behavioral control explained 67% of the variance in intentions. Perceived behavioral control explained 8% of the variance in walking activity. Conclusion: Findings support the theory of planned behavior for predicting intentions and warrant future examination of perceived behavioral control as a determinant of exercise. A basis for developing interventions to facilitate walking among this population is provided. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Immune homeostasis in the permanent inhabitants of mountain regions

Based on the study of 66 miners in the subclinical stage of manganotoxicosis the principle functional changes have been ascertained in the given condition. Revealed in the above series were an increased content of manganese in the hair of more than 3 mg% (95.5%-100.0%), the presence of neurosis-like condition presenting with elements of somatized depression, anxiety, asthenization, slight decline in the mnestic functions (69.6%-93.5%), mild impairment of the power of voluntary movement, parasympathetic type vegetative dystonia (42%-73.7%), slight changes in cerebral and peripheral hemodynamics (36.6%-68.6%), disordered bioelectrical activity of muscles of the extrapyramidal type (53.7%-83.2%), breakdown of mechanisms of adaptation of the sympathoadrenal (19.1%-49.3%) and cholinergic (26.3%-57.9%) systems.     

Improving the quality of life of caregivers of persons with spinal cord injury: A randomized controlled trial.

Objective: To assess the efficacy of two psychosocial interventions for caregivers of older persons with spinal cord injury (SCI). Design: A multisite, three-group, randomized controlled trial comparing two active intervention conditions with each other and to an information-only control group. One hundred seventy-three caregiver and care-recipient dyads were randomly assigned to one of three conditions: a caregiver-only treatment condition in which caregivers received a multicomponent intervention based on their risk profile; a dual-target condition in which the caregiver intervention was complemented by a treatment targeting the care recipient, designed to address both caregiver and care recipient risk factors; and an information-only control condition in which the caregiver received standard printed information about caregiving, SCI, and aging. Outcome Measures: A multivariate outcome comprised of six indicators linked to the goals of the interventions was the primary outcome of the study. The multivariate outcome included measures of depressive symptoms, burden, social support and integration, self-care problems, and physical health symptoms. Results: At 12 months, caregivers in the dual-target condition had improved quality of life as measured by our multivariate outcome when compared to the control condition. Using the dyad as the unit of analysis, the dual-target condition was superior to both the control condition and the caregiver-only condition in our multivariate outcomes analysis. Dyads enrolled in the dual-target condition had significantly fewer health symptoms than control condition and caregiver-only condition participants and were less depressed when compared to participants in the caregiver-only condition. In follow-up analyses we found that a higher proportion of caregivers in the dual-target condition had clinically significant improvements in depression, burden, and health symptoms when compared with the caregiver-only condition. Conclusion: Caregivers are in need of and can benefit from interventions that help them manage the medical and functional limitations of the care recipient. Intervention strategies that target both the caregiver and care recipient are particularly promising strategies for improving the quality of life of caregivers.

Long-Term Memory Deficits in Schizophrenia: Primary or Secondary Dysfunction?

Long-term memory impairment is often found in schizophrenia. The question remains whether this is caused by other cognitive deficits. One hundred eighteen first-episode patients were compared with 45 control participants on several memory tasks. The role of processing speed and central executive functions on memory performance was examined with regression analysis for all participants and for patients separately. Deficits were found in general verbal learning performance and retrieval in episodic memory and semantic memory. Processing speed reduced disease-related variance in all memory variables. Coordination, organization of information, and speed of processing were the best predictors for long-term memory deficits in patients. The amount of explained variance, however, is small, especially in general verbal learning performance. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Social problem-solving abilities, social support, and adjustment among family caregivers of individuals with a stroke.

ABSTRACT. Objective: To investigate the unique contributions of social problem solving abilities and social support in the prediction of aspects of caregiver adjustment. Study Design: Correlational procedures were used to determine the unique contributions of social problem-solving abilities and social support in the prediction of caregiver depression, health, and life satisfaction. Mediating factors were examined with correlational and regression analyses. Participants: Caregivers of individuals who had a stroke (20 African Americans and 20 Caucasians). Main Outcome Measures: The general health scale from the Short-Form Health Survey and measures of life satisfaction and depression. Results: Social support was the best predictor of caregiver life satisfaction. Perceived control over emotions when solving problems was the best predictor of caregiver depressive behavior and health. Social problem-solving abilities were associated with caregiver depressive behavior and health; social support did not mediate these relationships. Conclusions: Problem-solving interventions may be most appropriate for the treatment and prevention of caregiver depression and health problems. Social support programs may be indicated for caregiver life satisfaction. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Evidence that self-affirmation reduces alcohol consumption: Randomized exploratory trial with a new, brief means of self-affirming.

Objective: To test the ability of a new, brief means of affirming the self (the “self-affirming implementation intention”) to decrease alcohol consumption against a standard means of self-affirmation (the self-affirming “kindness” questionnaire) and an active control condition; to test whether self-affirmation effects can be sustained beyond the experimental session; and to examine potential moderators of the effects. Method: Two hundred seventy-eight participants were randomly allocated to one of three conditions: control questionnaire, self-affirming questionnaire, and self-affirming implementation intention. All participants were exposed to a threatening health message, designed to inform them about the health risks associated with consuming alcohol. Main Outcome Measures: The main outcome measure was subsequent alcohol intake. Results: There were significant public health gains and statistically significant decreases (>1 unit/day) in alcohol consumption in the two experimental conditions but not in the control condition. At the end of the study, participants in the control condition were consuming 2.31 units of alcohol per day; people in the self-affirming questionnaire condition were consuming 1.52 units of alcohol per day; and people in the self-affirming implementation intention condition were consuming 1.53 units of alcohol per day. There were no significant differences between the self-affirming questionnaire and self-affirming implementation intention, and adherence did not moderate the effects. Self-affirmation also improved message processing, increased perceived threat, and led to lower message derogation. Conclusions: The findings support the efficacy of a new, brief self-affirmation manipulation to enhance the effectiveness of health risk information over time. Further research is needed to identify mediators of the effects of self-affirmation on health behavior change. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

The associations between self-rated vision and hearing and functional status in middle age

OBJECTIVES: To describe the associations between self-reported visual and hearing impairment and an index of global functional status among community-dwelling, middle-aged Americans. DESIGN: Cross-sectional. PARTICIPANTS: A total of 9744 U.S. community-dwelling persons 51 to 61 years of age participated. METHODS: Multivariate analyses of functional status based on cross-sectional data from Wave I (1992) of the Health and Retirement Study (HRS), controlling for demographic and socioeconomic status, common chronic medical conditions, and general health status, were performed. MAIN OUTCOME MEASURE: A global index of functional status based on self-reported limitations in 17 activities was measured. RESULTS: Approximately 3% of respondents in the HRS rated their vision or hearing as poor. Even after controlling for demographic factors, socioeconomic status, medical conditions, and general health status, limitations in both vision and hearing were independently correlated with worse functional status. In addition, controlling for income, wealth, and education reduced the strength of the associations between vision and hearing impairment and function, but did not eliminate them. The magnitude of effect of poor vision exceeded all medical conditions except stroke. CONCLUSIONS: Visual and hearing impairment appear to have a significant relationship with overall functional status, among even community-dwelling, middle-aged Americans and even after controlling for general health status, medical comorbidities, and socioeconomic status.     

How self-affirmation reduces defensive processing of threatening health information: Evidence at the implicit level.

Objective: Self-affirmation reduces defensive responses to threatening health information, but little is known about the cognitive processes instigated by self-affirmation. This study tested whether self-affirmation increases responsiveness to threatening health information at the implicit level. Design: In an experimental study (N = 84), the authors presented high- (coffee drinkers) and low-relevance (noncoffee drinkers) participants with threatening health information linking caffeine consumption to health problems. Prior to reading this information, the authors manipulated self-affirmation. Main Outcome Measures: Participants completed an unobtrusive lexical decision task to measure the accessibility of threat-related cognitions and reported their perceptions of message quality and intentions to take precautions. Results: Among high-relevance participants, self-affirmation increased the accessibility of threat-related cognitions, increased perceptions of message quality, and promoted adaptive behavioral intentions. Conclusion: The findings suggest that self-affirmation can increase implicit responsiveness to threatening health information among a target audience, that is, people for whom the health information is highly relevant.

If it changes it must be a process: Study of emotion and coping during three stages of a college examination.

108 undergraduates completed a stress questionnaire in class 2 days before the midterm, 5 days after the midterm and 2 days before grades were announced, and 5 days after grades were announced. Results show that for Ss as a whole, there were significant changes in emotions and coping (including the use of social support) across the 3 stages. Some Ss experienced seemingly contradictory emotions and states of mind during every stage of the encounter; Ss experienced both threat emotions and challenge emotions, reflecting ambiguity regarding the multifaceted nature of the examination and its meanings (especially during the anticipatory stage). Ss used combinations of most of the available forms of problem-focused coping and emotion-focused coping at every stage. Problem-focused coping was more prominent in the anticipatory stage and distancing more prominent during the waiting stage. An analysis of selected appraisal and coping values, taking GPAs into account, explained about 48% of variance in threat and challenge emotions at the anticipatory stage. Including grade, 57% of the variance in positive emotions at outcome and 61% of negative emotions at outcome were explained. (49 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)
