Retrospective reports of parental partner abuse: Relationships to depression,trauma symptoms and self-esteem among college students

This study tested whether retrospective reports of childhood exposure to parental partner abuse were associated with internalizing aspects of adult adjustment. Participants were 550 men and women college students. Among women, childhood exposure to partner abuse was related to depression, trauma-related symptoms, and low self-esteem; among men, exposure was associated with trauma-related symptoms. These relationships were statistically independent of reported parental alcohol abuse and divorce. Relationships of parental partner abuse to low self-esteem and depression among women were also independent of variation in retrospective reports of child sexual and physical abuse. However, the relationship of partner abuse to trauma-related symptoms depended, in part, on the co-occurrence of child abuse. The discussion addressed implications of the findings for future research and for clinical practice.     

Strain and Opportunity Structures

Traditional strain theory received substantial empirical attention for a prolonged period of time, but it currently occupies a marginal position in criminology. Efforts to revitalize and elaborate it have occurred under the rubric of Agnew's general strain theory. These theories share a focus on how contextual factors, in particular what are commonly referred to as opportunity structures, affect the relationship between stresses and strains and delinquency. Using national-level data, this study considers empirically the impact of several illegitimate opportunity structures conceptualized at the school-level on the association between strain, stressful life events, delinquency, and self-concept. The results indicate that both stress and strain affect changes in delinquency and self-concept over time. Yet there is little evidence that these relationships are conditioned by access to illegitimate opportunity. These results suggest that strain and stress affect delinquency uniformly across a variety of illegitimate opportunity structures.     

The impact of stress on cognitive components of child abuse potential

The purpose of the present research was to test the effects of situational stress on the components of the cognitive behavioral model, including expectations, interpretations, and behavioral responses to child behaviors (Twentyman et al., 1985). It was predicted that parental abuse potential would be positively related to inappropriate expectations, to negative and internally caused interpretations of child behavior, and to negative parental responses. Second, it was expected that interpretations and responses would be more negative as child abuse potential increased. Sixteen mothers from a child abuse prevention and treatment program completed the Child Abuse Potential Inventory (Milner and Wimberly, 1980) and provided interpretations, evaluations, and responses to a set of vignettes depicting normal child behaviors. The data supported the hypotheses. As abuse potential increased, parent responses were judged as more controlling, punishing, rejecting, and aroused. High stress strengthened the magnitude of these responses. These findings were interpreted within the context of a cognitive behavioral model.     

Hostility and stress as mediators of aggression in violent men

This research investigated hypothesized differences on the Buss-Durkee Hostility Inventory between five groups of men who varied in terms of being violent toward female cohabitants, nonfamily members, or no one, and in terms of marital satisfaction. Other measures, such as stress and childhood abuse data, were employed to interpret the findings. A two-way MANCOVA (group by race) with six sociodemographic covariates revealed significant differences on three Hostility Inventory subscales. The maritally violent men had significantly higher total Hostility than any of the other groups and were significantly discriminable from the other groups. Nonetheless, the beliefs and behaviors of violence-prone individuals overlap to some degree. A cognitive-behavioral model with stimulus variables of life Stressors, intervening variables of hostility and negative stress reactions, and response variables of different forms of aggression served as a framework for interpreting the results.     

Adjustment of Homeless Adolescents to a Crisis Shelter: Application of a Stress and Coping Model

The present study examined the utility of a stress and coping model of adaptation to a homeless shelter among homeless adolescents. Seventy-eight homeless adolescents were interviewed and completed self-administered scales at Time 1 (day of shelter entry) and Time 2 (day of discharge). The mean duration of stay at the shelter was 7.23 days (SD = 7.01). Predictors included appraisal (threat and self-efficacy), coping resources, and coping strategies (productive, nonproductive, and reference to others coping). Adjustment outcomes were Time 1 measures of global distress, physical health, clinician- and youthworker-rated social adjustment, and externalizing behavior and Time 2 youthworker-rated social adjustment and goal achievement. Results of hierarchical regression analyses indicated that after controlling for the effects of relevant background variables (number of other shelters visited, sexual, emotional, and physical abuse), measures of coping resources, appraisal, and coping strategies evidenced distinct relations with measures of adjustment in ways consistent with the model's predictions with few exceptions. In cross-sectional analyses better Time 1 adjustment was related to reports of higher levels of coping resources, self-efficacy beliefs, and productive coping strategies, and reports of lower levels of threat appraisal and nonproductive coping strategies. Prospective analyses showed a link between reports of higher levels of reference to others coping strategies and greater goal achievement and, unexpectedly, an association between lower self-efficacy beliefs and better Time 2 youthworker-rated social adjustment. Hence, whereas prospective analyses provide only limited support for the use of a stress and coping model in explaining the adjustment of homeless adolescents to a crisis shelter, cross-sectional findings provide stronger support.     

Critical incidents,alcohol and trauma problems,and service utilization among police officers from five countries

This study examines the relationship between critical incidents, alcohol problems, trauma symptoms, and service utilization across five countries. A sample of 1286 police officers (79% male; 21% female) from five countries (US = 838, Canada = 231, UK = 102, Australia = 58, and New Zealand = 57) completed the Alcohol Use Disorders Identification Test (AUDIT) and the PTSD Checklist – Civilian PCL-C, as well as questions regarding service availability and utilization in an on-line survey. ANOVA and chi-square tests indicate significant country differences on all variables except social stressors. Multivariate analysis of critical incidents, AUDIT, PTSD, and service utilization found negative coping and country of origin mattered. The reasons officers provided for why they felt they could not use available services (i.e., confidentiality, stigma, distrust of department, and ineffective/inadequate) also varied by country, which has important policy implications.

Correlates of hopelessness in the high suicide risk police occupation

Police officers are chronically exposed to work stress. We examined specific stressors that may be associated with hopelessness, a possible risk factor for suicide in this high suicide risk population. The study included 378 officers (276 men and 102 women) with complete data. Analysis of variance was used to estimate mean levels of hopelessness scores as associated with stress, adjusted for age, gender, and race/ethnicity. Posttraumatic symptoms were tested as a modifier of the association between stress and hopelessness. Increasing stress of administrative practices and lack of support were significantly associated with increasing hopelessness among officers (p < .006 – hopelessness range: 1.64–2.65; and p < .001 – hopelessness range 1.60–2.80, respectively). Posttraumatic stress disorder (PTSD) symptoms significantly modified the association between lack of organizational support and hopelessness (p < .010) with significant association only among individuals with higher PTSD symptoms (p < .001). Results suggest that hopelessness is associated with specific stressors in police work, and this is modified by posttraumatic symptomatology.     

Intimate Partner Violence as a Risk Factor for Mental Disorders: A Meta-Analysis

This article reviews literature on the prevalence of mental health problems among women with a history of intimate partner violence. The weighted mean prevalence of mental health problems among battered women was 47.6% in 18 studies of depression, 17.9% in 13 studies of suicidality, 63.8% in 11 studies of posttraumatic stress disorder (PTSD), 18.5% in 10 studies of alcohol abuse, and 8.9% in four studies of drug abuse. These were typically inconsistent across studies. Weighted mean odds ratios representing associations of these problems with violence ranged from 3.55 to 5.62, and were typically consistent across studies. Variability was accounted for by differences in sampling frames. Dose-response relationships of violence to depression and PTSD were observed. Although research has not addressed many criteria for causal inferences, the existing research is consistent with the hypothesis that intimate partner violence increases risk for mental health problems. The appropriate way to conceptualize these problems deserves careful attention.
