A Lifestyle Risk Reduction Model for Preventing High-Risk Substance Use Across the Lifespan.

While effective models of alcohol and drug prevention exist, they often focus solely on youth or young adults. This article describes the Lifestyle Risk Reduction Model (LRRM), an approach applicable across the lifespan. The intent behind the LRRM is to guide the development of prevention and treatment programs provided to individuals and small groups. The LRRM authors' goals are to help individuals reduce risk for impairment, addiction, and substance use's negative consequences. The LRRM identifies six key principles that conceptualize the development of substance-related problems by drawing parallels with health conditions, such as heart disease and diabetes, which often result from combined effects of biological risk and behavioral choices. The model also proposes five conditions that describe important steps for individuals as they progress toward greater perception of risk and lower risk behavior. One LRRM-based indicated prevention program (Prime For Life) shows positive results in cognitive outcomes and in impaired driving recidivism for people across the lifespan. The model emphasizes common elements across the lifespan, responds to contexts and challenges that change across the life course, complements other models, and is usable for universal, selective, and indicated prevention programs.

Posttraumatic Stress Disorder Symptoms, Intimate Partner Violence, and Relationship Functioning: A Meta-Analytic Review.

This meta-analysis was the first study of which we are aware to investigate the association between Diagnostic and Statistical Manual of Mental Disorders (4th ed., text rev.; DSM-IV-TR; American Psychiatric Association, 2000) PTSD symptom clusters and parent, child, family, and marital/partner functioning problems (e.g., intimate partner violence [IPV] and intimacy). Of the 23 studies that met inclusion criteria, the sample was predominantly male (83.8%), Caucasian (65.0%), and from the military (98.9%). The average age was 43.65 years old (SD = 6.27); the average sample size was 397.4 (SD = 416.9; total N = 9,935). PTSD symptom clusters were assessed primarily by self-report (87.0%), with 8.7% using a rating by a clinician. We used fixed analysis following Fisher's r to z transformation and an unbiased weighing and summing of effect sizes within samples and across studies. We found a small association between hyperarousal and IPV (z = .20). We also found two moderate associations for the emotional numbing and avoidance symptom clusters: (a) with parent, child, and family functioning (z = .32, z = .28, respectively); and (b) with intimacy problems (z = .35, z = .42, respectively). We found two large associations for emotional numbing: marital and parent problems (z = .47) and parent, child, and family functioning problems (z = .32, respectively). Our findings suggested that treatments aim to lessen the effect on those who have close relationships with the individual with PTSD.

Associations Between Family History of Substance Use, Childhood Trauma, and Age of First Drug Use in Persons With Methamphetamine Dependence.

OBJECTIVES: The current study examined the association among family history of substance use problems, childhood maltreatment, and age of first drug use in a sample of men and women seeking treatment for methamphetamine dependence. Various forms of childhood maltreatment were considered as mediators of the association between family history of substance use problems and age of first drug use. METHODS: Participants (N = 99, 40% women, mean age 33) who were under treatment for methamphetamine dependence completed a baseline interview that obtained demographic information, past substance use by participants, history of drug/alcohol problems in their family of origin, and age at first use of any drug (excluding alcohol and tobacco). The Early Trauma Inventory Self-Report-Short Form was used to assess child maltreatment experiences before the age of 18. RESULTS: Family history of substance use problems and childhood physical (but not emotional or sexual) trauma significantly predicted age of first drug use. Further, childhood physical trauma mediated the association between family history of substance use problems and age of first drug use. CONCLUSIONS: These findings suggest that the experience of childhood physical abuse may be an important mechanism through which family history of substance use is associated with an earlier age of first drug use.

Does it hurt to ask? A meta-analysis of participant reactions to trauma research.

Institutional Review Boards (IRBs) are sometimes hesitant to approve trauma-related research due to concerns that asking participants about traumatic experiences will induce extreme distress. Despite the growing empirical literature examining participants' reactions to trauma-related research, no quantitative reviews have been conducted. The present multilevel meta-analysis was undertaken to quantify: (1) how participants react to trauma-related research overall; (2) to what extent reactions to trauma-related research differ by participant characteristics, including personal history of trauma, PTSD symptoms, and gender; and (3) to what extent (a) type of traumatic experience and (b) mode of administration moderate these effects. Studies examining adult participants' reactions to trauma assessments in the context of research were included. Results from 73,959 participants across 70 samples suggest that although trauma-related research can lead to some immediate psychological distress, this distress is not extreme. This distress is greater for individuals with a trauma history or PTSD, particularly in studies involving interviews. However, individuals generally find research participation to be a positive experience and do not regret participation, regardless of trauma history or PTSD. There were no gender differences in reactions. Present findings, which suggest that trauma-related research can continue without harming participants, may help inform IRB decisions on trauma research.

Examining the Role of Antisocial Personality Disorder in Intimate Partner Violence Among Substance Use Disorder Treatment Seekers With Clinically Significant Trauma Histories.

This study examined the associations among posttraumatic stress disorder (PTSD) symptom severity, antisocial personality disorder (ASPD) diagnosis, and intimate partner violence (IPV) in a sample of 145 substance abuse treatment-seeking men and women with positive trauma histories; sex was examined as a moderator. ASPD diagnosis significantly predicted both verbal and physical aggression; sex moderated the association between ASPD diagnosis and physical violence. PTSD symptom severity significantly predicted engaging in verbal, but not physical, aggression. Overall, these results suggest that an ASPD diagnosis may be an important risk factor for engaging in IPV among women seeking treatment for a substance use disorder.
