The induction of stem frost hardiness by low temperature, water stress, short days, and their combinations in 2- and 4-month-old growing dogwoods (Cornus stolonifera) were investigated. When plants were subjected to more than one factor, the increased hardiness was the sum of the effects of the individual factors involved. No interactions among these factors on hardiness were observed during a ...

The relation between nationality and selected indicators of psychological performance in rugby league football was examined. Mental toughness was assessed using the alternative Psychological Performance Inventory (PPI-A) and hardiness using the Personal Views Survey III-R (PVS III-R). Participants (N = 49, M age = 21.7 yr., SD = 2.3) were male elite-level university rugby league footballers rep...

Specific associations among perceived stress and hardiness can reflect the characteristics of workers in particular professions. The goals of this research were to analyze sets of correlations between the aspects of hardiness and experienced stress, separately for two subsamples of subjects in the research, and on the entire sample. Then, the goal was to determine the correlations among the asp...

Type A behavior and hardiness were examined as predictors of cardiovascular responses to stress in 68 male undergraduates. Systolic and diastolic blood pressure (SBP and DBP) and heart rate were monitored while subjects performed a difficult mirror-tracing task. Type A assessments based on the Structured Interview, but not those based on the Jenkins Activity Survey, were associated with signifi...

BACKGROUND Nursing students may exhibit the characteristics of resistance to stress, such as hardiness, which can reduce the risk of burnout. However, we found only one published study about these phenomena among nursing students. Thus, we investigated the association between hardiness and burnout in such students. METHODS An analytic, cross-sectional study was conducted among 570 nursing stu...

Alcohol abuse is a growing problem in the military, and a costly one. The present study evaluates the potential role of psychological hardiness, an individual resilience resource, to stress-related problem drinking in a military population. We assess the association of psychological hardiness and avoidance coping style with alcohol use patterns in a large national sample of Norwegian military d...

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 re...

Although cold hardiness is known to be a major determinant of tree species distribution, its dynamics and the factors that regulate it remain poorly understood. Variation in cold hardiness and carbohydrate concentration, from dormancy induction until bud burst, were investigated in populations of two deciduous (Quercus robur L. and Quercus pubescens Willd.) and one evergreen (Quercus ilex L.) E...

Psychological hardiness characterizes people who remain healthy under psychosocial stress. The present exploratory study investigates possible links between hardiness and several immune and neuroendocrine markers: IL-6, IL-12, IL-4, IL-10, & neuropeptide-Y. A total of 21 Norwegian navy cadets were studied in the context of a highly stressful military field exercise. Blood samples were collected...
