Problem Drinking, Unemployment, and Intimate Partner Violence among a Sample of Construction Industry Workers and their Partners

The purpose of this study is to determine the contribution of male unemployment and each partner’s problem drinking to risk for male-to-female partner violence (MFPV) and female-to-male partner violence (FMPV) among a sample of construction industry workers and their spouses/partners. Participants in the sample (n = 848 couples) completed cross-sectional health behavior surveys. Multivariate logistic regression models of MFPV and FMPV, with adjustment for demographic and psychosocial variables, were developed. Approximately 20% of couples reported MFPV, and 24% reported FMPV. Results indicated that couples in which the male was a problem drinker, and in which the male worker reported being currently unemployed, were at risk for MFPV. Number of months unemployed by the male worker was significantly associated with FMPV, but problem drinking was not associated with this outcome. Male and female impulsivity were significantly associated with risk for MFPV and FMPV, and the male’s report of adverse childhood events was associated with increased likelihood of MFPV. There was no evidence for the effects of unemployment being moderated (exacerbated) by problem drinking. Workplace-based prevention efforts may be a feasible and important strategy to reduce problem drinking and partner violence among high-risk occupational groups.

Day laborers and occupational stress: testing the Migrant Stress Inventory with a Latino day laborer population

Although day laborers are likely to suffer from high rates of work-related stress, there are no survey measures that focus on stress among this occupational group. Accordingly, we tested the validity and reliability of the Migrant Stress Inventory (MSI), a scale originally designed for migrant farmworkers. Based on survey data collected from day laborers (N = 102) in two Northern California communities, the MSI was found to have adequate internal consistency, yet additional analyses indicated a different factor structure for the subscales. New subscales (relationships, communication, alcohol and other drug use, years in the United States, age, deportation concerns, discrimination experience) with this sample had strong reliability, as well as construct validity. In all, 57.8% of day laborers experienced high rates of stress, and factor analysis differentiated four stressor domains: instability, relationships, communication, and alcohol and other drug use. Moreover, 39.2% of respondents reported lifetime difficulties with alcohol, although alcohol difficulties were not associated with stress. Implications for further research are discussed based on these findings.

The Impact of Occupational Culture on Drinking Behavior of Young Adults in the U.S. Navy

A mixed method study assessed how work culture and drinking norms affect heavy drinking patterns of young adults during their first 3 years in the U.S. Navy. Multivariate logistic regression analysis of the longitudinal survey data showed that normative beliefs were significantly associated with changes in drinking. Findings from thematic analyses of qualitative interviews and naturalistic observations on bases and aboard ships explained those elements of U.S. Navy culture and work environments that affect normative beliefs about drinking behavior.

Measuring intimate partner violence among male and female farmworkers in San Diego County, CA.

Although there are over one million farmworkers in the United States, little is known about intimate partner violence (IPV) among this population. Given the particular demands of agricultural labor, however, farmworkers and their partners are highly susceptible to a host of occupation-specific stressors that may result in relationship conflict, and thereafter IPV. In cases where one or both members of the dyad engage in problematic drinking, the likelihood of violence increases exponentially. The purpose of this exploratory quantitative study was to estimate the prevalence of IPV among a mixed gender sample of farmworkers in San Diego County, California, and assess the association of potential correlates (acculturation- and work-related stress, problem drinking, and impulsivity) to IPV. Bilingual interviewers conducted survey data collection by using standardized instruments (e.g., Revised Conflict Tactics Scale; Migrant Farm Work Stress Inventory; AUDIT). Nearly all participants (n = 100) were Mexican born. Results showed that approximately 16% of female individuals (n = 61) and 32% of male individuals (n = 37) reported partner violence perpetration, victimization, or both, in the past year. Significant correlates of IPV were problem drinking (among males) and impulsivity (among females). This study demonstrates the feasibility of conducting IPV research among male and female farmworkers. Additional research is warranted to more fully explore the role of acculturation- and work-related stress, drinking, and other personal characteristics and environmental factors in precipitating couple conflict and thereafter IPV.

Challenges of Contraceptive Use and Pregnancy Prevention Among Women in the U.S. Navy

In this article we present the results of a study to illuminate the explanatory factors related to unplanned pregnancies in the United States Navy, particularly with regard to female contraceptive training and practices, and occupational culture. The data set consists of 52 semistructured interviews with key informants, sailors, and enlisted personnel who were recruited via a quota sample stratified by gender, occupation, and location. The research team carried out semistructured interviews at seven different naval facilities in the mainland United States, the South Pacific, and Europe. Textual analysis of the interview data revealed four domains pertinent to unplanned pregnancies: (a) ineffective training for women regarding contraceptive options, proper dosing, and potentially negative side effects; (b) discrepancies between contraceptive knowledge and their proper use; (c) different foci of contraceptive training for men (sexually transmitted infection prevention) and women (pregnancy prevention); and (d) cultural norms that equate contraceptive use with promiscuity.

The relationship of alcohol problems to the risk for unidirectional and bidirectional intimate partner violence among a sample of blue-collar couples

Understanding how each partner’s alcohol problems may contribute to the risk of male-to-female only, female-to-male only, or bidirectional partner violence is important for the prevention and treatment of these problems. Multinomial regression analysis was conducted using data from 848 blue-collar couples. Findings suggest that male alcohol problems are linked to male-to-female and bidirectional partner violence but not with female-to-male partner violence. Female alcohol problems do not appear to be related to any type of partner aggression. Each partner’s level of impulsivity was associated with bidirectional partner violence. Male impulsivity was associated with male-to-female violence, and female impulsivity was associated with female-to-male violence. Prevention of male alcohol problems and promotion of nonconfrontational conflict-solving techniques may help reduce partner aggression among couples in the general household population.
