Purpose
To examine differences between members of protective service occupations (PSOs) and other occupational groups on indicators of alcohol use/abuse and mental health.Methods
A subset of 25,622 observations from the 2009 National Survey of Drug Use and Health (NSDUH) are used to evaluate whether PSO members exhibit a higher likelihood of problematic drinking behaviors and if so, whether these behaviors are mediated by mental health problems.Results
Logistic regression models indicated that PSO members do not consume alcohol more frequently nor do they exhibit higher likelihood of alcohol abuse/dependency when compared to members of other occupational groups. However, PSO members report higher occurrence of binge drinking. The relationship between PSOs and binge drinking behaviors is mediated by gender, not mental health problems.Conclusion
The results provide direction for the development of evidence-based alcohol related intervention programs that address the specific needs of police officers and other public servants. 相似文献44.

This study examined the relationship between the characteristics of childhood sexual abuse (CSA) and the severity of consequent posttraumatic stress disorder (PTSD), depression, suicidal ideation, and substance use in a sample of 83 female adolescents aged 13–18 years seeking treatment for PTSD. Nearly two-thirds of the sample (60.7 %, n?=?51) reported the perpetrator of the CSA was a relative. A large portion (40.5 %, n?=?34) of the sample reported being victimized once, while almost a quarter of the sample reported chronic victimization (23.8 %, n?=?20). PTSD and depression scores were in the clinical range, whereas reported levels of suicidal ideation and substance use were low. The frequency of victimizations was associated with suicidal ideation. Contrary to expectation, CSA characteristics including trauma type, perpetrator relationship, and duration of abuse were unrelated to PTSD severity, depressive symptoms, or substance abuse. 相似文献

Objectives
This study tracked the behavior of male inmates housed in the general inmate populations of 70 different prison units from a large southern state. Each of the inmates studied engaged in violent misconduct at least once during the first 2 years of incarceration (n = 3,808). The goal of the study was to isolate the effect of exposure to short-term solitary confinement (SC) as a punishment for their initial act of violent behavior on the occurrence and timing of subsequent misconduct.Methods
This study relied upon archival longitudinal data and employed a multilevel counterfactual research design (propensity score matching) that involved tests for group differences, event history analyses, and trajectory analyses.Results
The results suggest that exposure to short-term solitary confinement as a punishment for an initial violence does not appear to play a role in increasing or decreasing the probability, timing, or development future misconduct for this particular group on inmates.Conclusions
Upon validation, these findings call for continued research and perhaps a dialog regarding the utility of solitary confinement policies under certain contexts. This unique study sets the stage for further research to more fully understand how solitary impacts post-exposure behavior.48.
