Health practices and hardiness as mediators in the stress-illness relationship

Two stress and illness models that include the joint mediating effects of health practices and hardiness were tested prospectively over a 2-month period. At the beginning of one academic quarter, 60 female and 26 male undergraduate students completed five subscales indexing hardiness. Stress, health practices, and illness for the prior month were assessed at this time as well as 1 and 2 months later. Stress was measured by the number of negatively rated stressors reported on the Life Experiences Survey. Health practices were measured by the Self Care Inventory. In the first model, illness was measured by the severity of physical symptoms reported on the Seriousness of Illness Rating Scale; in the second model, it was measured by the number of symptoms reported. Correlations between all measures of stress and illness were typical for life events research (r = .22 to .29). In both models, path analyses revealed that stress acted directly to affect illness as well as indirectly by changing health practices. Hardiness also had a direct effect on illness as well as in indirect effect through health practices. Hardiness did not appear to have a stress-buffering effect on illness; rather, its effects on illness appeared to be independent of its effects on stress. Implications for life events research are discussed.     

Staying fit and staying well: physical fitness as a moderator of life stress

Previous research suggests that physical fitness moderates the adverse effects of stressful life events. However, a reliance on self-reports of fitness and health may limit the validity of prior investigations. The present research tested the stress-buffering effect of fitness with subjective and objective indicators of exercise, fitness, and physical well-being. For self-reports of health, both self-reports of exercise and objective measures of fitness showed the buffering effect; however, only objective fitness levels buffered stress when visits to a health facility were considered. Additional evidence indicated that this effect was largely independent of measures of psychological distress. Implications for understanding the link between fitness, stress, and health status are discussed.     

Personality and social resources in stress resistance

This study examined personality, social assets, and perceived social support as moderators of the effects of stressful life events on illness onset. In a group of 170 middle and upper level executives, personality hardiness and stressful life events consistently influenced illness scores, the former serving to lower symptomatology, the latter to increase it. Perceived boss support had its predicted positive effect. Executives under high stress who perceived support from their supervisors had lower illness scores than those without support. Perceived family support, on the other hand, showed a negative effect on health when reported by those low in hardiness. Finally, social assets made no significant impact on health status. These results underscore the value of differentiating between kinds of social resources, and of monitoring the effects of two or more stress-resistance resources in a single study.     

Physical exercise and anxiety as moderators of the stress-illness relationship

This study examines the interplay of unemployment stress, trait anxiety and physical exercise in the development of physical health. Longitudinal data were taken from a sample of East German migrants (N = 330) who were confronted with the potentially stressful demand of finding a job in the Western society. Unemployment stress was found to exert a main effect on illness level. Trait anxiety was a moderator of the stress-illness relationship, but exercise was not. As indicated by a three-way interaction involving exercise, anxiety, and stress, exercise was most beneficial among high-anxious subjects who were not exposed to unemployment stress. Results of this study suggest that exercise may not buffer the deleterious effects of stressful situational conditions (unemployment), but may effectively mitigate the health-damaging consequences of lacking personal resources, such as high dispositional anxiety.     

Appraisal of life change, depression, and illness in hardy and nonhardy women

A survey study of adult women was conducted to examine whether psychological hardiness buffers people against stressful life change through the appraisal and interpretation of life experiences. Hardy and nonhardy participants reported life events for the previous year, physical illness for the previous 6 months, and current levels of depression and rated each reported event in terms of its desirability. Results indicate that, although hardiness is not associated with the likelihood of reporting any specific life event, nonhardy subjects appraise a significantly higher proportion of their life experiences as undesirable than do hardy subjects and report that each negative event requires greater adjustment. Discussion focuses on nonhardiness as a correlate of the trait of negative affectivity rather than hardiness as a reflection of special resiliency to stress.     

Hardiness, type A behavior, and the stress-illness relation in working women

Hardiness has been proposed as a stress-resistance resource in maintaining health. This construct has been shown to act in conjunction with the Type A behavior pattern in affecting illness. In this study, we examined this relation in women (N = 82) with the use of the Structured Interview and the Jenkins Activity Survey to assess Type A behavior. As expected, there was a strong stress-illness association. However, there were no hardiness main effects nor interactions between stress, Type A behavior, and hardiness. Hardiness was significantly associated with age, education level, and marital status. No differences in hardiness composition were found between high stress/high illness and high stress/low illness groups. Only the Powerlessness scale of hardiness was related to illness. These results are discussed in comparison with other hardiness studies. Particular attention is focused on possible sex differences, and implications for future research are suggested.     

Mindfulness-Based Stress Reduction and Sense of Coherence Among Women with Fibromyalgia

Sense of Coherence (SOC) is conceptualized as a disposition to experience life as meaningful and manageable. Research suggests a protective effect of SOC on psychological health in stressful circumstances. This study assessed the capacity of SOC to buffer the effect of illness symptoms on psychological distress among patients with fibromyalgia. Self-reported changes in SOC after participation in a Mindfulness-Based Stress Reduction (MBSR) program were also examined. Ninety-one women with fibromyalgia provided baseline data pertaining to illness symptoms, perceived stress, and depression prior to participation in a randomized trial of MBSR. SOC and fibromyalgia symptoms were independently related to perceived stress and depression at baseline. SOC was not a statistically significant moderator of symptom effects on psychological distress. In comparison with wait-listed controls, program participants reported a significant increase in SOC after MBSR participation. These results provide the first demonstration from a randomized trial that SOC may be enhanced via intervention.     

Exercise as a buffer of life stress: a prospective study of adolescent health

The hypothesis that physical exercise provides benefits to individuals under periods of life stress has rarely been subject to empirical verification. This article presents the results of a longitudinal study of stress and well-being in adolescence in which the ability of exercise to buffer stress-induced deteriorations in physical health was examined. In accordance with predictions, prospective analyses revealed that the negative impact of stressful life events on health declined as exercise levels increased. These findings suggest that exercise may be a valuable resource for combating life stress. Discussion centers on possible mediating mechanisms and on the practical implications of the results.     

Hardiness and health: a critique and alternative approach

Recent research has suggested that individual differences in the personality variable of hardiness are related to health and illness. Despite some success at predicting health outcomes, there are several theoretical and empirical problems that must be addressed before research on this topic can proceed. Most critical are (a) how hardiness is to be measured; (b) whether hardiness should be treated as a unitary phenomenon or as three separate phenomena associated with commitment, control, and challenge; and (c) whether hardiness has direct effects on health or indirect effects by virtue of buffering the impact of stressful life events. After reviewing the literature and presenting our own study of the psychometric properties of the Hardiness Scale and its subcomponents, we draw the following conclusions: (a) Hardiness is not a unitary phenomenon, but should be treated as involving three separate phenomena; (b) of the three subcomponents of hardiness, only commitment and control have adequate psychometric properties and are systematically related to health outcomes; (c) lack of control and lack of commitment have direct effects on health because they are psychologically stressful; and (d) if there are buffering effects of commitment and control, they are in addition to these direct effects and are situation specific. Such a systematic consideration of the problems and prospects of the hardiness literature should facilitate research on this important topic.

Psychological Hardiness Predicts Success in a Norwegian Armed Forces Border Patrol Selection Course

The present study investigates the effects of psychological hardiness and successful completion of a rigorous 250‐km ski march over 9 days in Arctic winter conditions. This ski march is the final portion of a selection program for border rangers in the Norwegian Armed Forces. Study participants were N = 178 soldiers with a mean age of 19.9 years (range 18–23). Hierarchical regression results showed that successful completion of the ski march was predicted by total hardiness scores, after controlling for nutrition factors, physical fitness and sensation seeking. A second hierarchical regression found that the commitment facet of hardiness was the most significant predictor of ski march success, again controlling for nutrition, physical fitness and sensation seeking. Analyses of daily participant surveys showed that the high commitment group reported the highest levels of positive daily coping, and also evaluated their performance more positively. This group also showed increasingly positive self‐evaluations as the exercise went on. Together, these results indicate that hardiness commitment is a key factor influencing performance in a rigorous and stressful endurance task requiring sustained effort, perhaps by enhancing active coping skills and self‐efficacy beliefs.     

Stress,strain, and hardiness as predictors of adaptation in farm and ranch families

We examined the relationship between potential family vulnerability factors (stressor and strains), manifestations of maladaptation (family discord and distress), family strengths (hardiness), and measures of bonadaptation (quality of life) as reported by 188 men and women representing 100 Idaho farm and ranch families. Family strains, and stressors unique to farming and ranching, were positively associated with family discord and distress but negatively associated with hardiness and quality of life. Greater family hardiness as reported by both wives and husbands was positively correlated with their perceptions of family quality of life. The results have implications for mental health professionals and family life educators whose goal is to help farm and ranch families manage stress more effectively, increase hardiness, and enhance their overall quality of life.     

Hardiness and mental health during naval deployment: The relation is mediated by social processes and not by self-regulatory processes

IntroductionThe aim of the present study was to investigate the mediating effects of cohesion and self-efficacy on the relation between hardiness and symptoms of anxiety and depression during naval international operations.Objective and methodIt was hypothesized that an indirect effect of both cohesion and operational self-efficacy would emerge even when controlling for pre-deployment measures of symptoms.ResultsThe results revealed a strong indirect effect of cohesion on the relationship between hardiness and scores on Hopkins Symptom Checklist – 25 items. The effect was evident for the total score and the dimensions of anxiety as well as depression. No effect was found for operational self-efficacy.ConclusionIt was concluded that the social process of cohesion outperforms the self-regulatory process of operational self-efficacy as a mediator between hardiness and mental health. Greater focus on developing crew cohesion may thus be important for maintaining mental health under stressful conditions.     

Reduced emotional stress reactivity to a real-life academic examination stressor in students participating in a 20-week aerobic exercise training: A randomised controlled trial using Ambulatory Assessment

ObjectivesTo examine if a preventive 20-week aerobic exercise intervention (AET) can improve emotional stress reactivity during real-life stress.DesignRandomised controlled trial; within-subject design.MethodSixty-one inactive students were randomly assigned to a waiting control and an AET group. To capture the situation-specific, intra-individual data in real life, electronic diaries were used. Participants reported their moods and perceived stress (PS) repeatedly over two days during their daily routines pre- and post-intervention. The pre-intervention baseline assessment was scheduled at the beginning of the semester, and the post-intervention assessment was scheduled at a real-life stressful episode, an academic examination. For the aerobic fitness assessment, both groups completed a cardiopulmonary exercise test on the treadmill before and after the intervention. Multilevel models (MLMs) were conducted to compare within- and between-subject associations.ResultsSignificant emotional stress reactivity was evident in both groups during all assessment periods. However, participants in the AET group showed lower emotional stress reactivity compared with their control counterparts after the 20-week training programme during the real-life stress episode (the academic examination).ConclusionsAET conferred beneficial effects on emotional stress reactivity during an academic examination, which is likely an extremely stressful real-life situation for students.AET appears to be a promising strategy against the negative health effects of accumulated emotional stress reactivity.     

The influence of hardiness on the relationship between stressors and psychosomatic symptomatology

Thirty male and 58 female students responded to questionnaires based on a 9-month period in a prospective study of the impact of hardiness, life events, and hassles on reports of somatic symptoms. The data were analyzed utilizing cross-lagged panel analyses, analyses of variance, and multiple regression analyses. The results suggested that life events, hassles, and symptoms were significantly related in a recursive, mutually interactive manner. Although life events shared a high degree of variance with hassles, hassles consistently contributed above and beyond life events in predicting somatic symptoms. In addition, hardiness tended to have additive and opposite effects to that of stressors in its impact on symptomatology. Finally, and perhaps most important, compared to lower-hardy individuals, those higher in hardiness tended to experience less frequent stressors and to perceive the minor events they did experience as less stressful.     

Hardy personality: a potential link with organizational citizenship behavior

Hardiness is a personality construct which is assumed to protect the individual from stress-induced illness. Although widely accepted, hardiness has shown only modest relations with the development of illness. Examining the components of hardiness indicates apparent consistency with organizational citizenship behaviors such as obedience, participation, and loyalty. This study investigated the potential relations between hardiness and organizational citizenship behavior, using Kobasa's Personal Views Survey, and Van Dyne, Graham, and Diensch's citizenship measure. Subjects were 129 unionized employees whose mean age was 37 yr.; 58% were men. Correlations and regressions indicated that scores for total hardiness and its components of commitment and control were linked to citizenship behaviors. Differential relationhips were identified between hardiness and citizenship behavior for individuals with high versus low scores on hardy personality. Hardiness appears to have a positive association with organizational effectiveness through its link to citizenship behavior and consequently may have more implications for organizational behavior than for health.     

Stress,healthiness and health behaviours: An exploration of the role of life events,daily hassles,cognitive appraisal and the coping process

In a study of 220 participants, the relationship between life events, daily hassles, cognitive appraisal and coping, stress and general healthiness was investigated utilizing a self report methodology. The different aspects of healthiness and health behaviour/lifestyle appear to be related to different appraisal and coping styles. The role of daily hassles and life events in the process also vary across different aspects of health, illness and health behaviours. In fact the number of life events experienced appear to contribute more to hardiness than to vulnerability. It is proposed that to understand the process an integrative model is required which allows for flexibility in analysis.     

Longitudinal investigation of reciprocal relationship between stress reactions and hardiness

Although many studies have examined hardiness as a protective factor against stress reactions, to the authors' knowledge no studies have yet examined the impact of stress reactions on hardiness. However, there is theoretical support for this notion. In this longitudinal study of 1,571 Marine recruits who participated in a highly stressful training program, the authors applied regression-based cross-lagged analyses to examine associations between stress reactions and hardiness over time for both men and women, and they investigated social support as a moderator of these relationships. Men who were hardier at Time 1 (T1) reported lower stress reactions at Time 2 (T2), and men who experienced more stress reactions at T1 were less hardy at T2. Although the negative impact of stress reactions on hardiness was strongest when social support was low for both genders, stress reactions predicted enhanced hardiness when social support was high for women only.     

Parentification,Stress, and Problem Behavior of Adolescents who have a Parent with Mental Health Problems

When adolescents live with a parent with mental illness, they often partly take over the parental role. Little is known about the consequences of this so‐called parentification on the adolescents' internalizing and externalizing problems. This survey study examined this effect cross‐sectionally and longitudinally in a sample of 118 adolescents living with a parent suffering from mental health problems. In addition, the study examined a possible indirect effect via perceived stress. Path analyses were used to examine the direct associations between parentification and problem behavior as well as the indirect relations via perceived stress. The results showed that parentification was associated with both internalizing and externalizing problems cross‐sectionally, but it predicted only internalizing problems 1 year later. An indirect effect of parentification on adolescent internalizing and externalizing problems via perceived stress was found, albeit only cross‐sectionally. These findings imply that parentification can be stressful for adolescents who live with a parent with mental health problems, and that a greater awareness of parentification is needed to prevent adolescents from developing internalizing problems.     

The Relationship of Hardiness, Gender, and Stress to Health Outcomes in Adolescents

The present study examined the relationship between the hardiness components of commitment, control, and challenge, and the experience of physical and psychological symptoms in a sample of 150 (75 male, 75 female) adolescents. A measure of psychosocial stress was included to permit an examination of whether the hardiness components interact with stress in predicting health outcomes. Analyses revealed main effects of stress, gender, and the hardiness components of commitment and control for several of the health measures. More important was the finding of a consistent interaction of stress, gender, and hardiness for several of the health measures. Whereas low-stress males experienced few physical and psychological symptoms regardless of their levels of commitment and control, high-stress males experienced more problems when they were low rather than high in either commitment or control. The hardiness components did not interact with stress in the prediction of health outcomes among females.
