Stress, Energy, and Immunity: An Ecological View

ABSTRACT— A common perspective on stress-related changes in the human immune system is that such changes are potentially harmful, especially those occurring during chronic stress. In contrast, an ecological perspective views the immune system as an energetically costly system that may or may not have priority over other uses of that energy. From this perspective, the immune system may have energy made available for it via reduction of other activities, may change in energetically conservative ways when the protection it confers needs to be balanced with the energetic demands of other activities such as fight or flight, or may be suppressed when other activities are more important than immunity for total well-being. This last type of change can explain why aspects of psychosocial health such as optimism relate to worse immunity under some circumstances and suggests that both benefits and costs of immunosuppression during stress should be considered in research on human stress and immunity.     

心理应激与DNA损害

心理应激不仅能使人的行为特征发生变化,而且也能使人的生理状况发生改变,因此,被认为是某些身心疾病的诱因。在此过程中,DNA损害是心理应激造成的最终结果之一。有关DNA损害,虽然以往的研究者以人或动物为对象进行了一系列急性应激和慢性应激的实验研究,但是,心理应激是如何造成DNA损害的过程还不清楚,具体的生理心理机制还未阐明。该文利用健康心理学提出的理论模型对此进行了分析,阐述了心理应激与DNA损害之间联系的可能的机制,强调了氧化应激在这一过程中的重要作用。同时,为临床制订预防疾病的干预措施提供了思路     

Stress and Immunity: Age Enhances the Risks

A competent immune response is central to good health. There is good evidence that both aging and psychological stress can dysregulate immune function, resulting in changes in various aspects of the immune response that are large enough to have consequences for health. Older adults appear to show even greater immunological impairments associated with stress or depression than younger adults. Thus, the data suggest that aging interacts with stress and depression to enhance risks for morbidity and mortality among older adults.     

Psychological Research, Practice, and Production: The Occupational Stress Problem

The accumulation of research findings now suggest a significant work stress problem, with implications for worker health, motivation and productivity, that warrants a concerted applied research effort at a local level and a strategy and policy response at a national level. Psychologists need to rethink prevailing paradigms that often separate their research and practice. We argue that a conducive production model that emphasizes action and knowledge, and reciprocal learning between academia, practitioners, and organizations may be the way forward for psychologists to respond effectively to the current work stress problems and other emergent organizational issues. Failure to do so may result in exacerbation of problems related to the psychological and social context of work, a slowed response to increased demands, and an ever decreasing practical utility of the profession.     

Racism‐Related Stress,General Life Stress,and Psychological Functioning Among Black American Women

The relationship between general life stress, perceived racism, and psychological functioning was explored in a sample of 118 Black American women. Findings indicate that racism‐related stress was not a significant predictor of psychological functioning when controlling for general life stress. Perceived racism was positively associated with general life stress. Implications for practice and future research are discussed. La relación entre el estrés general de la vida, el racismo percibido y el funcionamiento psicológico se exploraron en una muestra de 118 mujeres afroamericanas. Los resultados indican que el estrés relacionado con el racismo no fue un pronosticador significativo del funcionamiento psicológico cuando se controló estadísticamente para tomar en cuenta el estrés general de la vida. El racismo percibido estuvo asociado positivamente con el estrés general de la vida. Se discuten las implicaciones para la práctica e investigaciones futuras.     

Missile Stress, Help-Seeking Behavior, and Psychological Reaction to the Gulf War

We studied the effects of missile stress, appraised before the 1991 Gulf War, and help-seeking behavior employed during it on affective reactions to the war. These reactions included the negative strains of anxiety and helplessness and the positive affect of improved self-competence. Respondents were 257 civilians, all residents of metropolitan Tel Aviv, Israel, the area targeted by most of the Iraqi missile attacks. Data were gathered by telephone interviews conducted with the respondents about a month before the war and again about 2 weeks after the war's end. As predicted, missile stress and help-seeking behavior were both positively correlated with anxiety and helplessness. It was found, as predicted, that for those who engaged in intensive help-seeking behavior, the negative effects of missile stress on improved self-competence were more pronounced.     

Effects of Spiritual Well-Being on Subsequent Happiness,Psychological Well-Being,and Stress

Recently, Gomez and Fisher (Gomez R and Fisher JW (2003) Pers Individ Dif 35: 1975–1991) proposed that four facets of spiritual well-being exist, namely, personal, communal, environmental, and transcendental spiritual well-being. Based on data from three independent studies, the present research effort tested the validity of a German version of (Gomez R and Fisher JW (2003) Pers Individ Dif 35: 1975–1991) of the Spiritual Well-Being Questionnaire (SWBQ-G). It was found that the SWBQ-G was factorially valid and that each of the four SWBQ-G scales was discriminant to mental, physical, and emotional well-being. Also, it was found that the SWBQ-G predicted levels of subsequent happiness, psychological well-being (positive relationship), and stress (negative relationship). These results add to our knowledge about the validity of the construct of spiritual well-being.     

The Relationship between Psychological Capital,Coping with Stress,Well-Being,and Performance

This study examined coping with stress from an organizational perspective by positing a relationship between Psychological Capital (PsyCap) and coping strategies (defined as change, accepting, or withdrawal). It was hypothesized that coping strategies would mediate the relationship between PsyCap and people’s well-being and performance. Questionnaire findings from a five hundred and fifty four employees showed a significant relationship between PsyCap and coping. Coping strategy in terms of change partially mediated the relationship between PsyCap and the outcomes of well-being and performance. Coping strategy in terms of withdrawal partially mediated the relationship between PsyCap and performance. PsyCap was found to have a strong, positive, and direct correlation with well-being and performance. Well-being was not found to associate significantly with performance. These findings suggest that the central variable in the model is not coping but PsyCap. PsyCap appears to have a strong, direct, and significant effect on the dependent variables. The theoretical implications are examined and future research avenues suggested.     

Differentiation of Self, Stress, and Emotional Support as Predictors of Psychological Distress

We explored the relations among stress, emotional support, and differentiation of self from the family of origin as predictors of psychological distress in a sample of 200 college students. First, we investigated the discrepant findings of Murdock and Gore (Contemp Fam Ther 23: 319–335, 2004) and Skowron et al. (J Couns Dev 82: 69–78, 2004) regarding the relationships among stress, differentiation, and symptoms (a question of mediation vs. moderation). Second, we examined the role of emotional support in concert with stress and differentiation. When both stressful events and perceived stress were measured, differentiation of self was found to be a significant partial mediator of their effects on psychological distress. Emotional support was also found to partially mediate the relationship between differentiation of self and psychological distress. Differentiation of self partially mediated the relationship between actual and perceived stress, and perceived stress partially mediated the relationship between differentiation of self and psychological distress.     

Marital Stress, Psychological Distress, and Healthful Dietary Behavior: A Longitudinal Analysis

This longitudinal study examined the role of marital and psychological distress on healthful dietary change. A theoretical model is proposed that specified barriers to healthful dietary behavior as mediating the effect of depressive symptoms, role disagreement, inequity, and education on dietary change over time. Subjects were 97 married couples interviewed in their homes at 2 separate times. Selection in the first wave was by random area sampling based on population concentration. The findings provide evidence of the negative influence of interpersonal and intrapsychic distress on positive dietary change. For wives, marital and psychological distress and the barriers to dietary change were important factors in actual changes in dietary behavior. For both husbands and wives, higher barriers were associated with lesser positive dietary change.

Moderate Aerobic Exercise, T'ai Chi, and Social Problem-Solving Ability in Relation to Psychological Stress

This study evaluated the importance of exercise mode, social problem-solving ability, gender, and age in relation to anxiety and perceived daily hassles. Adult participants were classified as moderate aerobic exercisers, T'ai Chi exercisers, or sedentary via completion of a questionnaire. Social problem-solving ability, state and trait anxiety, and frequency and severity of daily hassles were measured. As predicted, scores indicating effective social problem-solving ability were associated with fewer reported severe daily hassles and with lower scores on state and trait anxiety. For state and trait anxiety, a main effect of exercise mode emerged after age and gender were controlled. A 3-way interaction involving age, gender, and exercise mode suggested that age and gender moderate the effects of exercise on anxiety, that is, the stress-reducing efficacy of different exercise modes may be dependent on a person's age and/or gender. Implications for theory, research, and practice are discussed.

USAF Special Tactics Operator Combat Exposure and Psychological Stress

Given the length of combat in Afghanistan, Iraq, Syria, and elsewhere, and the role special operations forces will continue to play, we believe it is imperative to gain understanding of the psychological “wear and tear” associated with sustained combat operations on these highly specialized, highly utilized personnel. This study focused on a seldom-studied group, Air Force Special Tactics (ST) operators, to assess combat exposure, current psychological stress, and preferences for support when needed. This study assessed symptoms of posttraumatic stress, depression, anxiety, sleep, anger, and perceptions of help seeking in 5 ST units. Data revealed that the majority of study participants report distress levels below clinical thresholds; however, 26% struggle with generalized stress/agitation and, at smaller percentages, other distress symptoms that have negative impact on work performance. Combat experiences were comparable or higher than Army and Marine maneuver forces, and greater amounts of exposure related to positive screening for a possible mental health disorder, generalized agitation, and posttraumatic symptoms; combat involving direct fighting and being in high-threat situations were also related to posttraumatic stress. Distress rates for Special Operations Weather personnel were higher. Attitudes toward mental health support were positive however, embedded assets were preferred over base clinic providers. We review these and other findings and offer suggestions for future research in this area.     

Secondary Traumatic Stress,Psychological Wellbeing and Life Satisfaction of Social Workers in Namibia

The aim of this study was to investigate the relationships among secondary traumatic stress, psychological wellbeing (purpose in life, environmental mastery and self-acceptance) and life satisfaction of social workers of Namibia. A cross-sectional survey design was used with a sample population of 116 social workers. The Secondary Traumatic Stress Scale, three subscales of the Psychological Well-being Scale, the Satisfaction with Life Scale and a biographical questionnaire were administered. The results showed that secondary traumatic stress (including arousal, avoidance and intrusion) was negatively related to purpose in life, environmental mastery, self-acceptance and life satisfaction of social workers. Satisfaction with life was best predicted by environmental mastery and low arousal. Avoidance impacted life satisfaction indirectly and negatively via low environmental mastery.     

Neighborhood Environment, Sexual Risk Behaviors and Acquisition of Sexually Transmitted Infections Among Adolescents Diagnosed with Psychological Disorders

The association between neighborhood environment and prevalence of STIs, sexual partner variables and condom use among adolescents with psychological disorders was examined. Cross-sectional data in three urban areas of the US (Southeast, Northeast and Midwest) were obtained from 384 sexually active male and female participants who provided urine samples for laboratory-confirmed testing of Neisseria gonorrhoeae, Chlamydia trachomatis and Trichomonas vaginalis. A total of 15.4% of participants tested positive for one of the three STIs. Results indicated that relative to adolescents living in low risk neighborhood environments, those living in high risk environments were significantly more likely to have a STI and to report having casual partners. Findings suggest that in high risk neighborhoods, STI acquisition may be less dependent on condom use and more dependent on other contextual factors. The importance of expanding public health research to include assessment of neighborhood context as a determinant of sexual risk-taking is emphasized.
