Major life events, hassles, and adaptation in adolescence: Confounding in the conceptualization and measurement of life stress and adjustment revisited.

Prior work has suggested that methodological and conceptual confounding may play a role in the associations obtained between stressful life events, social resources, and adaptive outcome. Of particular concern in our work were (a) the source and method of assessment; (b) conceptual overlap between life stress and resource items and symptoms of disorder; and (c) induced response bias through the instructional sets of stress measures. A second goal was to extend our understanding of the life stress–adjustment linkage in groups for whom little data of this type exist. By using multitrait-multimethod procedures we found that both distal major life events and proximal daily stressors had important degrees of unique and shared variance with adaptive functioning, whereas the effects for social support were inconclusive. Further, the importance of considering possible sources of potential confounding in producing quite different levels of association between life stress and adaptation was underscored by the results.

Combining major life events and recurrent hassles in the assessment of stress in Chinese adolescents: Preliminary evidence.

Major life events and hassles have been considered 2 distinct constructs in the measurement of stress. Research also shows that chronic events are more impactful than time-limited ones. This study reports a new approach to measuring stress in which major life events are combined with recurrent hassles to form a single index—the Adolescent Stress Index (ASI). High school students (N = 365) in Hong Kong responded twice at a 3-month interval to measures of major life events and hassles, the ASI, and measures of physical and depressive symptoms. Data were analyzed using structural equation modeling. Results showed that the ASI predicted symptoms concurrently and prospectively above and beyond the effects of existing measures of major life events and hassles. The ASI is a viable instrument for documenting the cumulative impact of major and minor events in the lives of adolescents. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Physical activity and quality of life in multiple sclerosis: Possible roles of social support, self-efficacy, and functional limitations.

Objective: Quality of life (QOL) is compromised among individuals with multiple sclerosis (MS). Physical activity has been positively associated with QOL, but little is known about the factors that explain and/or confound the relationship in those with MS. On the basis of a social-cognitive perspective and previous research, the authors tested the hypothesis that physical activity would be indirectly associated with QOL through a mediated pathway that included self-efficacy and functional limitations, after controlling for perceived social support. Participants: Participants were 196 individuals with a definite diagnosis of MS living in the Midwest region of the United States who completed a battery of questionnaires and wore a pedometer and accelerometer for a 7-day period. Results: Covariance modeling analyses indicated that physical activity was indirectly associated with QOL through a pathway that included self-efficacy and functional limitations, and the pattern of relationships was independent of the perception of social support. Conclusions: The findings support physical activity as a possible modifiable behavior for mitigating reductions of QOL in those with MS and suggest that a social-cognitive model aids in the understanding of physical activity's relationships with QOL.

Symptoms, hassles, social supports, and life events: Problem of confounded measures.

Recent stressful life events are related to a wide variety of psychological and physical disorders, but the relations have tended to be minimal. This has led investigators to introduce such factors as "hassles" and "social supports" in expanded investigations of life-stressed processes. As with life events scales, however, questions have been raised about whether the conceptual and operational distinctions have been clear enough to permit clear investigation of interrelations among these factors and adverse health changes. The present study examined judgments by 371 clinical psychologists of the extent to which items in leading stress instruments are likely to be symptoms of psychological disorder. Results indicate that each of the stress measures was confounded with measures of psychological distress, the Hassles Scale and the Instrumental-Expressive Support Scale more so than the Social Readjustment Rating Scale. Types of life events and social supports are discussed in terms of their relative dependence on personality and psychopathology.

Comorbidity of substance dependence and depression: Role of life stress and self-efficacy in sustaining abstinence.

The authors examined life stress and self-efficacy as predictors of time to relapse for 113 adults with comorbid major depressive disorder and alcohol and/or substance dependence in a randomized clinical trial comparing 2 psychotherapy interventions (integrated cognitive- behavioral therapy and 12-step facilitation therapy). Life stress, self-efficacy, and substance use were assessed at treatment entry, 12 weeks (mid-treatment), and 24 weeks (end of treatment). Time to relapse was defined as the number of days from treatment initiation until first alcohol and/or drug use. Half of the sample relapsed within the study period of 24 weeks. There was no significant difference between treatment groups. Individuals experiencing life stressors were more likely to relapse early than those not experiencing life stressors. Lower self-efficacy also predicted earlier relapse. Chronic stress levels and self-efficacy were stable across time for most individuals. In contrast, acute stress events occurred at differing times, and survival analyses provided evidence of heightened relapse risk in the month following acute stressors. The interaction of self-efficacy and life stress was not significant. The results highlight the significance of life stress and self-efficacy as predictors of early relapse.

Relationship of daily hassles, uplifts, and major life events to health status.

100 45–64 yr olds completed a hassles scale, an uplifts scale, a recent life events schedule, and a health status questionnaire. Analysis showed that hassles—the repeated or chronic strains of everyday life—were more strongly associated with somatic health than were life events. Hassles shared most of the variance in health that could be accounted for by life events, and when the effects of life events were statistically removed, hassles and health remained significantly related. Daily uplifts made little contribution to health that was independent of hassles. The assessment of daily hassles appears to be a useful approach to the study of life stress and could be an important supplement to the life events approach that, alone, is insufficient for full understanding and practical prediction of health outcomes.

Sex roles and social support as moderators of life stress adjustment.

In this study we used a longitudinal design to test the stress-buffering effects of sex role orientation in combination with perceived social support on measure of trait anxiety and depression. College undergraduates served as subjects. The cross-sectional analysis provided strong support for the hypothesis that masculinity would function as a life stress buffer. The hypothesis that social support would serve as a stress buffer when coupled with high masculinity was supported by one of the cross-sectional analyses as well as the longitudinal analysis. This pattern was found primarily for perceptions of tangible social support. The longitudinal analysis also revealed a significant interaction involving negative life events and masculinity and femininity. This interaction effect provided unexpected support for a balance model of androgyny, in that non-sex-typed subjects showed greater resilience to recent life stress than did sex-typed subjects. The findings are discussed in terms of their implications for the study of life stress adjustment. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Enhancing role breadth self-efficacy: The roles of job enrichment and other organizational interventions.

Role breadth self-efficacy (RBSE) refers to employees' perceived capability of carrying out a broader and more proactive set of work tasks that extend beyond prescribed technical requirements. A newly developed scale of RBSE was internally consistent and distinct from the related concepts of proactive personality and self-esteem. In an initial cross-sectional study (n?=?580), work design variables (job enrichment, job enlargement, and membership of improvement groups) were the key organizational predictors of RBSE. These investigations were repeated in a second cross-sectional study (n?=?622) and extended by examining change over time (n?=?459). The longitudinal analysis showed that increased job enrichment and increased quality of communication predicted the development of greater self-efficacy.

The incremental validity of vocational self-efficacy: An examination of interest, self-efficacy, and occupation.

The authors examined the incremental validity, beyond vocational interest, of the General Confidence Themes of the Skills Confidence Inventory (N. E. Betz, F. H. Borgen, & L. W. Harmon, 1996a) as measures of vocational self-efficacy in identifying tenured and satisfied membership in 21 occupational groups for 1,105 employed women and men. The General Occupational Themes of the Strong Interest Inventory (L. W. Harmon, J. C. Hansen, F. H. Borgen, & A. L. Hammer, 1994) were used to measure interest. The results replicated T. J. G. Tracey's (1997) finding that self-efficacy and interest form similar structures. Results also demonstrated the explanatory power of self-efficacy and interest and the incremental validity of self-efficacy. The authors suggest that the Skills Confidence Inventory is (a) a valid measure of tenured and satisfied occupational membership, (b) a distinct measure from interest but similar in structure, and (c) a potentially useful career assessment measure.

Psychological stress and coping in aging.

Examines how the dynamics of stress and coping change with circumstances of living and processes of aging. The answer has remained obscure for 3 main reasons. (1) The state of the art in the measurement of stress and coping is still primitive. (2) Personal beliefs, values, and commitments, which develop from a person's unique history, shape appraisal of stress and manner in which stress is coped with and therefore have profound consequences for morale, social and work functioning, and somatic health. (3) Most of the observations relevant to the central question have been obtained cross-sectionally; however, because the significance of any given event is embedded in the individual's personal, lifelong drama, it is important to examine stress and coping longitudinally as well.

Impact of pulmonary rehabilitation on self-efficacy, quality of life, and exercise tolerance.

Objective: The objective of the present study was to investigate changes in psychological, physiological, and behavioral-performance variables as a function of pulmonary exercise rehabilitation. Study Design and Participants: Forty patients diagnosed with chronic obstructive pulmonary disease (COPD) were recruited for participation in a 12-week outpatient pulmonary rehabilitation program. Measures: Measures included 6-min walking distance (exercise tolerance), 6-min walking distance self-efficacy, overall quality of life, dyspnea, fatigue, and emotional function. Results: Results revealed significant improvements over the course of the program in each of these measures, regardless of disease severity. In addition, improvements in exercise tolerance were significantly associated with increases in self-efficacy, which, in turn, were significantly related to improved quality of life. Conclusions: The results support the tenets of social-cognitive theory and suggest that participation in an outpatient pulmonary rehabilitation program can provide both physiological and psychological benefits for individuals with COPD.

Effects on teachers' self-efficacy and job satisfaction: Teacher gender, years of experience, and job stress.

The authors of this study sought to examine the relationships among teachers' years of experience, teacher characteristics (gender and teaching level), three domains of self-efficacy (instructional strategies, classroom management, and student engagement), two types of job stress (workload and classroom stress), and job satisfaction with a sample of 1,430 practicing teachers using factor analysis, item response modeling, systems of equations, and a structural equation model. Teachers' years of experience showed nonlinear relationships with all three self-efficacy factors, increasing from early career to mid-career and then falling afterwards. Female teachers had greater workload stress, greater classroom stress from student behaviors, and lower classroom management self-efficacy. Teachers with greater workload stress had greater classroom management self-efficacy, whereas teachers with greater classroom stress had lower self-efficacy and lower job satisfaction. Those teaching young children (in elementary grades and kindergarten) had higher levels of self-efficacy for classroom management and student engagement. Lastly, teachers with greater classroom management self-efficacy or greater instructional strategies self-efficacy had greater job satisfaction.

The relationship between employment-related self-efficacy and quality of life following traumatic brain injury.

Objectives: This study examines the relative contribution of employment-related and general self-efficacy to perceptions of quality of life (QoL) for individuals with traumatic brain injury. Design: Correlational. Setting: Community-based research and training center. Participants: 427 individuals with self-reported TBI under the age of 65 were included in analysis. Main Outcome Measure: Employment-related self-efficacy, general self-efficacy, perceived quality of life (PQoL), unmet important needs (UIN). Results: Significant correlations were found between income, injury severity, age at injury, and employment and the QoL variables. In addition, employment-related and general self-efficacy correlated positively with both PQoL and UIN. Employment-related and general self-efficacy accounted for 16% of the variance in PQoL and 9.5% of the variance in UIN, over and above other variables traditionally associated with QoL. Conclusions: These findings highlight the importance of including subjective appraisals of employment, such as perceived self-efficacy at the workplace, in assessing QoL and successful return to work following TBI.

Work stress, self-efficacy, Chinese work values, and work well-being in Hong Kong and Beijing.

The authors tested the direct and moderating effects of self-efficacy and Chinese work values on relationships between job stressors and work well-being among employees in Hong Kong and Beijing. A self-administered questionnaire survey was conducted to collect data from 105 and 129 employees in Hong Kong and Beijing, respectively. The results revealed that self-efficacy was positively related to job satisfaction in both samples. Self-efficacy was found to be a stress moderator in some of the stressor-work well-being relationships for both samples. The direct effect of Chinese work values on work well-being was minimal, and its moderating effects were partially demonstrated in some of the stressor-job satisfaction relationships.

Adjustment following the mass shooting at Virginia Tech: The roles of resource loss and gain.

Unfortunately, many individuals will be exposed to traumatic events during their lifetime. The experience of loss and gain of valued resources may represent important predictors of psychological distress following these experiences. The current study examined the extent to which loss and gain of interpersonal and intrapersonal resources (e.g., hope, intimacy) predicted psychological distress among college women following the mass shooting at Virginia Tech (VT). Participants were 193 college women from whom preevent psychological distress and social support data had been obtained. These women completed surveys regarding their psychological distress, coping, and resource loss and gain 2- and 6-months after the VT shooting. Structural equation modeling supported that resource loss predicted greater psychological distress 6 months after the shooting whereas resource gain was weakly related to lower levels of psychological distress. The study also revealed that social support and psychological distress prior to the shooting predicted resource loss, and social support and active coping with the shooting predicted resource gain. Implications of the results for research examining the roles of resource loss and gain in posttrauma adjustment and the development of interventions following mass trauma are discussed.

The relationship of perceived self-efficacy to quality of life in chronic obstructive pulmonary disease.

From a biomedical perspective, variations in the quality of life of chronic obstructive pulmonary disease (COPD) patients may be attributed to changes in pulmonary function, thus, an increase in lung function should be correlated with an increased score on a health-related quality-of-life measure. However, inconsistent results regarding correlations between various measures of pulmonary function and quality of life have been reported in the literature. The authors evaluated a social cognitive model of quality of life among persons with COPD by analyzing relationships among biomedical measures, self-efficacy measures, and quality-of-life measures in a recursive path model. Path analysis results indicated that the association of pulmonary function and symptoms with quality of life was mediated by perceived self-efficacy for functional activities.

Maladaptive perfectionism, hassles, coping, and psychological distress in university professors.

This study examined the roles of hassles, avoidant and problem-focused coping, and perceived social support as mediating the relationship between maladaptive perfectionism and psychological distress in a sample of university professors. Hassles and avoidant coping both partially mediated a strong association between maladaptive perfectionism and psychological distress. These results are discussed in terms of the need to better understand how coping styles and social support are associated with the negative impact of perfectionism on the lives of university professors. The implications of these findings for counseling practice are also explored. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The effects of stress on memory and the hippocampus throughout the life cycle: implications for childhood development and aging

Studies in animals showing hippocampal atrophy and associated memory deficits in stress and aging have implications for stress and aging in humans. Clinical studies in traumatized human populations with posttraumatic stress disorder (PTSD) have replicated studies in animals, showing reduction in volume of the hippocampus measured with magnetic resonance imaging and associated memory deficits. Trauma at different stages of development (early childhood abuse versus trauma in later life due to combat) may influence the nature of memory deficits and hippocampal atrophy. Studies in aging human subjects are consistent with animal studies, although future research is needed in this area. The similarities between biological findings related to cortisol and the hippocampus in stress and aging in both animal and human studies raises the question of whether PTSD can be seen as a form of accelerated aging. Evidence that stress affects the hippocampus and the capacity for learning has broad implications for public health policy, underlying the need for additional resources in this important area and a reexamination of our understanding of factors influencing academic achievement.     

The effect of multiple roles on caregiver stress outcomes.

Some caregivers focus exclusively on the caregiving role; others try to balance caregiving responsibilities with a simultaneous work role outside the home. This study examined competing hypotheses about the impact that greater immersion in a work role would have on the stress outcomes of individuals who provide care for a person with a disability. The authors used national survey data to examine whether hours of work were associated with caregiver stress outcomes. The authors also investigated whether type of disability moderated the relationship between hours worked and stress outcomes. Results suggest that spending more time in a work role generally has no effect on caregiver stress outcomes. However, caregivers who were caring for a person with a mental disability experienced significantly fewer stress outcomes as they spent more hours engaged in outside work.

Meaning making and psychological adjustment following cancer: The mediating roles of growth, life meaning, and restored just-world beliefs.

Cancer survivors' efforts at meaning making may influence the extent to which they successfully make meaning from their experience (i.e., experience posttraumatic growth, find life meaningful, and restore beliefs in a just world), which may, in turn, influence their psychological adjustment. Previous research regarding both meaning making processes and meanings made as determinants of adjustment has shown inconsistent effects, partly because of the lack of clearly articulated theoretical frameworks and problematic research strategies. In a 1-year longitudinal study, the authors distinguished the meaning making process from the outcomes of that process (meanings made), employing specific measures of both. The authors tested pathways through which meaning making efforts led to 3 different meanings made (growth, life meaning, and restored just-world belief) in a sample of 172 young to middle-age adult cancer survivors, and they explored whether those meanings made mediated the effect of meaning making efforts on psychological adjustment. Cross-sectional and longitudinal path models of the meaning making process indicate that meaning making efforts are related to better adjustment through the successful creation of adaptive meanings made from the cancer experience. The authors conclude with clinical implications and suggestions for future research. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
