Objective and subjective dimensions of travel impedance as determinants of commuting stress.

The stressful characteristics of commuting constraints are conceptualized in terms of both physical and perceptual conditions of travel impedance. This study develops and operationalizes the concept of subjective impedance, as a complement to our previously developed concept of impedance as a physically defined condition of commuting stress. The stress impacts of high-impedance commuting were examined in a study of 79 employees of two companies in the follow-up testing of a longitudinal study. Subjective impedance was overlapping but not isomorphic with physical impedance, and these two dimensions have differential relationships with health and well-being outcomes. The physical impedance construct received further confirmation in validational analyses and in predicted effects on various illness measures and job satisfaction. The newly constructed subjective impedance index was significantly related to evening home mood, residential satisfaction, and chest pain. Job change was also influenced primarily by commuting satisfaction. The results are discussed within an ecological framework emphasizing interdomain transfer effects and situational moderators of commuting stress.

Anger and combat-related posttraumatic stress disorder.

We examined whether combat-related PTSD was differentially associated with particular dimensions of anger on two multi-index, psychometric instruments and whether the proportion of variation in PTSD scores explained by anger was significantly greater than that by demographic and exposure variables. We also examined the reliability and validity of a subset of Mississippi Scale items as an anger measure. Participants were 143 Vietnam combat veterans. Anger accounted for over 40% of the variance in Mississippi PTSD scores (minus the anger items) above that associated with age, education, and combat exposure. Veterans with structured-interview–diagnosed PTSD were significantly differentiated from those without PTSD on all anger indices. The results point to anger treatment as a high priority for combat-related PTSD.

Assessment of anger and aggression in male offenders with developmental disabilities

Systematic assessment of anger among people with developmental disabilities has been lacking, especially for hospital inpatients. Reliability and validity of anger self-report psychometric scales were investigated with 129 male patients, mostly forensic. Anger prevalence and its relationship to demographic, cognitive, and personality variables and to hospital assaultive behavior were examined. High internal and intermeasure consistency, and some concurrent validity with staff ratings, were found. Retrospective validity regarding physically assaultive behavior in the hospital was obtained. Hierarchical regressions revealed that patient-reported anger was a significant predictor of assaults postadmission, controlling for age, length of stay, IQ, violence offense history, and personality variables.

Transportation, stress, and community psychology.

Conditions of transportation were investigated as sources of psychological stress as they affect the physiology, task performance, and mood of commuters. Participants in the study were 100 employees of industrial firms. Traffic congestion was construed as a behavioral constraint in terms of the concept of impedance which is defined by the parameters of distance and time. It was expected that the effects of impedance would be mediated by personality factors, such as locus of control. Multivariate tests of the internal validity of the impedance factor were significant. However, significant main effects for impedance were obtained only for mood and residential adaptation. The predicted interactions of impedance with locus of control were obtained across task performance indices. In multiple regression analyses, the distance and speed of the commute to work were found to account for significant proportions of variation in blood pressure, while several indices of personal control had significant regression effects on the task measures. The implications of the results for research in community psychology are discussed.

Psychological Distress of Children and Mothers in Domestic Violence Emergency Shelters

Abused mothers and their school-aged children who recently entered domestic violence emergency shelters were assessed by individual interview and psychometric measures. Children had positiveviews of the shelter residence. Mothers and children reported high-quality relationships with eachother. Children came from highly violent homes, and the majority had attempted to intervene in theinteradult violence. Hierarchical multiple regressions were conducted on child PTSD symptoms, child behavior problems, and maternal depression, anxiety, and anger. Child PTSD symptoms were associated with amount of physical violence. Child behavioral problems were related to mother anxiety andanger. The predictors of maternal emotional distress varied. Depression was associated with sexualabuse, child physical intervention, and quality of mother–child relationship; anxiety was related to witnessing child abuse, child age, and child internalizing behaviors; anger was associated with abuse-related injuries, violence frequency, and child internalizing behaviors. Augmentationof shelter-based interventions for childrens trauma, maternal emotional distress, and parenting are discussed.

Cognitive–behavioural therapy v. social activity therapy for people with psychosis and a history of violence: randomised controlled trial

BACKGROUND Aggression and violence are serious problems in schizophrenia. Cognitive-behavioural therapy (CBT) has been shown to be an effective treatment for psychosis although there have been no studies to date evaluating the impact of CBT for people with psychosis and a history of violence. AIMS To investigate the effectiveness of CBT on violence, anger, psychosis and risk outcomes with people who had a diagnosis of schizophrenia and a history of violence. METHOD This was a single-blind randomised controlled trial of CBT v. social activity therapy (SAT) with a primary outcome of violence and secondary outcomes of anger, symptoms, functioning and risk. Outcomes were evaluated by masked assessors at 6 and 12 months (trial registration: NRR NO50087441). RESULTS Significant benefits were shown for CBT compared with control over the intervention and follow-up period on violence, delusions and risk management. CONCLUSIONS Cognitive-behavioural therapy targeted at psychosis and anger may be an effective treatment for reducing the occurrence of violence and further investigation of its benefits is warranted.

Anger and Coping with Stress

Howard Beale, veteran anchorman of the Universal Broadcasting Company, became the mad prophet of the movie, Network, as he implored television audiences across the nation: So, I know you’ve been bugged. You’ve got to get mad. You’ve got to say, “I’m a human being, damn it! My life has value!” So, I want you to get up now. I want all of you to get up out of your chairs. I want you to get up right now and go to the window, open it, and stick your head out and yell, “I’m as mad as hell, and I’m not going to take this anymore!” Things have got to change, but first, you’ve got to get mad.

HOME ENVIRONMENT CONSEQUENCES OF COMMUTE TRAVEL IMPEDANCE

The physical and perceptual dimensions of commuting travel impedance were again found to have stressful consequences in a study of 99 employees of two companies. This quasi-experimental replication study, which focuses here on home environment consequences, investigated the effects of physical impedance and subjective impedance on multivariate measures of residential satisfaction and personal affect in the home. Both sets of residential outcome measures were significantly related to the two impedance dimensions. As predicted, gender was a significant moderator of physical impedance effects. Women commuting on high physical impedance routes were most negatively affected. Previously found subjective impedance effects on negative home mood, regardless of gender, were strongly replicated with several methods and were buttressed by convergent results with objective indices. The theoretical conjecture that subjective impedance mediates the stress effects of physical impedance was supported by the personal affect cluster but only for one variable in the residential satisfaction cluster. Traffic congestion has increased in metropolitan areas nationwide, and commuters, families, and organizations are absorbing associated hidden costs. The results are reviewed in terms of our ecological model, and the moderating effects of gender are discussed in terms of choice and role constraints.

Life Constraints and Psychological Well-Being of Domestic Violence Shelter Graduates

Psychosocial adjustment and life constraints of 81 domestic violence shelter graduates were examined via field interviews in the community, assessing women’s current life status, satisfaction with core life domains, and violence experience, pre- and post-shelter. Psychometric scales for depression and trauma symptoms were also administered. Participants had received extensive services in either an emergency or a transitional living shelter. Although fairly satisfied across life domains, many had serious post-shelter financial hardships. Most importantly, they reported remarkably little post-shelter violence exposure, either within or outside of romantic relationships. Despite now living independently, 43% and 75% reported clinical levels of depression and trauma symptoms, respectively. In hierarchical stepwise regressions, depression was related to women’s childhood sexual abuse, dissatisfaction with housing and their own parenting, and experience of financial difficulties conjoined with public assistance. Trauma symptoms were associated with childhood sexual abuse and post-shelter financial difficulties. The impaired psychosocial functioning and life difficulties of these predominantly successful domestic violence survivors highlights the need for specialized shelter intervention and continuity of care in the community.

Employment Frustration and Alcohol Abuse/Dependence Among Labor Migrants in California

We test whether or not labor market frustration is associated with clinical alcohol abuse/dependence diagnoses among labor migrants living in California. Our sample consists of 1576 Mexican labor migrants in Fresno, CA, who migrated for the purpose of seeking employment. Using clinical criterion (DSM-III-R), we find that frustrating experiences resulting from labor market exclusion and discrimination are significantly related to past-year alcohol abuse/dependence. Similarly, although high levels of social support are salutary, they are not protective among those who experience moderate/high levels of employment frustration. Since Mexican-origin immigrants have low rates of health insurance coverage and lower propensities for formal help-seeking, community outreach programs that target labor migrants are essential to this populations mental health maintenance.
