Resilience–recovery factors in post-traumatic stress disorder among female and male Vietnam veterans: Hardiness, postwar social support, and additional stressful life events.

Structural equation modeling procedures were used to examine relationships among several war zone stressor dimensions, resilience-recovery factors, and post-traumatic stress disorder symptoms in a national sample of 1,632 Vietnam veterans (26% women and 74% men). A 9-factor measurement model was specified on a mixed-gender subsample of the data and then replicated on separate subsamples of female and male veterans. For both genders, the structural models supported strong mediation effects for the intrapersonal resource characteristic of hardiness, postwar structural and functional social support, and additional negative life events in the postwar period. Support for moderator effects or buffering in terms of interactions between war zone stressor level and resilience-recovery factors was minimal.

Objective stress factors, accidents, and absenteeism in transit operators: A theoretical framework and empirical evidence.

The authors used observational job analysis as a conceptually based technique to measure stress factors unbiased by worker appraisal with 81 transit driving tasks on 27 transit lines. Stressor dimensions included work barriers that interfere with task performance due to poor technical-organizational design, time pressure, time binding (autonomy over time management), and monotonous conditions. Line-specific average stressor values were assigned to 308 transit operators who mainly worked the particular line. Logistic regression analyses showed associations for high work barriers and sickness absences (odds ratio [OR]=3.8, p=.05). There were elevated risks for work accidents for high time pressure operators (OR=4.0, p=.04) and for the medium time-binding group (OR=3.3, p=.04) and significant (alpha=.20) unadjusted interaction terms for barriers and time pressure in predicting accidents and absences, and barriers and time binding in predicting absences. Findings suggest guaranteed rest breaks and flexible timing for accident prevention and removal of work barriers for reducing absenteeism.

Defining Trauma: Terminology and Generic Stressor Dimensions1

The present report discusses vague and/ or confusing terminology that is employed in research and clinical work in the area of “traumatic stress”. It divides the stress process into three major aspects and suggests appropriate terminology for each aspect, focusing on the input, or stressor, aspect. Eight generic stressor dimensions are suggested that cut across different types of traumatic events, along with research supporting the association of these dimensions with stress responses. Recommendations are made for future research directions.
