Gender differences in comorbid disorders among offenders in prison substance abuse treatment programs

This study examined gender differences in a range of lifetime psychiatric disorders in a sample of 272 offenders newly admitted to a prison substance abuse program. Although these men and women did not differ in severity of substance use in the six months prior to incarceration, women were significantly more likely than men to report a lifetime psychiatric disorder and a lifetime severe disorder. Furthermore, gender differences emerged in the pattern of lifetime psychiatric comorbidity. Women reported greater lifetime major depression, posttraumatic stress disorder, eating disorder, and borderline personality disorder; men were more likely than women to meet criteria for antisocial personality disorder. Additionally, female offenders were found to have a higher degree of internalizing disorders than male offenders, but there were no gender differences in degree of externalizing disorders. The study concluded that women offenders newly admitted to a prison substance abuse program present with a greater psychiatric vulnerability and a different pattern of psychiatric comorbidity than their male counterparts.     

Diagnostic profiles of offenders in substance abuse treatment programs

This study examined the association of Axis I and Axis II disorders among offenders who were in prison-based substance abuse treatment in a national multi-site study. Participants (N = 280) received a psychosocial assessment and a structured diagnostic interview in two separate sessions. Logistic regression models examined the association between lifetime mood and anxiety disorders with two personality disorders, and the relationship of Axis I and Axis II disorders (alone and in combination) to pre-treatment psychosocial functioning. Over two-thirds of the sample met criteria for at least one mental disorder. Borderline personality disorder was strongly associated with having a lifetime mood disorder (odds ratio = 7.5) or lifetime anxiety disorder (odds ratio = 8.7). Individuals with only an Axis II disorder, or who had both Axis I and Axis II disorders, had more severe problems in psychosocial functioning than those without any disorder. Clinical treatment approaches need to address this heterogeneity in diagnostic profiles, symptom severity, and psychosocial functioning.     

Emotion Regulation and Parenting in AD/HD and Comparison Boys: Linkages with Social Behaviors and Peer Preference

Children's emotion regulation strategies and parenting responses in a family task that elicited frustration are investigated by, comparing core attention-deficit/hyperactivity disorder (AD/HD) symptomatology, emotional reactivity, and emotional regulation in the prediction of social behaviors and peer social preference. Participants were boys, ages 6–12 years, either with AD/HD (n = 45) or without problem behaviors (comparison; n = 34). A high-aggressive subgroup of AD/HD boys showed a significantly less constructive pattern of emotional coping than did both a low-aggressive AD/HD subgroup of boys and nondiagnosed comparison boys, who did not differ. With statistical control of core AD/HD symptomatology, noncompliance in a naturalistic summer camp was predicted by boys' overall emotion regulation and three specific strategies (emotional accommodation, problem solving, negative responses) during the parent–child interaction. Emotional accommodation and negative responses to the frustration task also marginally predicted social preference at the camp. These emotion regulation variables outperformed emotional reactivity in predicting such outcomes. Some emotion-related parenting behaviors were associated with child coping in the task. We discuss the relationship of emotion regulation to core AD/HD symptomatology and emotional reactivity, and the role of parents' behaviors in influencing children's emotional responses.     

Correlating brain metabolism with stereotypic and locomotor behavior

Many studies have shown that developmental cocaine exposure alters brain function and behavior; the present study examined the relationship between brain metabolism and behavioral responses to drug challenge. SKF 82958, a selective D1 dopamine agonist, was administered to preweaning cocaine-exposed (50 mg/kg/day) rats and controls at 60 days of age. Deoxyglucose was administered 30 min later, during the peak behavioral response, to measure brain functional activity Pearson product-moment correlations of behavior (locomotor activity and Stereotypic behavior) with rates of glucose metabolism in components of the nigrostriatal and mesolimbic circuits were analyzed. The analysis revealed that under saline-challenge conditions in control animals, rates of metabolism in mesolimbic regions are positively correlated to rates of locomotor activity, whereas in cocaine-treated rats, these correlations were absent. Following SKF challenge, a different pattern was seen; locomotor activity or Stereotypic behavior was not correlated with mesolimbic or nigrostriatal metabolism, respectively,in controls but was positively correlatedin cocaine-treatedrats. Therefore, cocaine exposure during development enhances the coupling of metabolism in components of the mesolimbic and nigrostriatal dopamine systems with the behavioral output associated with these systems under drug-challenge conditions. This may be due to loss of inhibitory influences within the mesolimbic and nigrostriatal systems. Thus, the correlation of behavior and cerebral glucose metabolism provides a unique way of examining the effect of developmental cocaine exposure.     

COD services in community correctional settings: an examination of organizational factors that affect service delivery

Little is known about service delivery for those in the correctional system with co-occurring mental health and substance abuse disorders (COD). Using data from the National Criminal Justice Treatment Practices survey (NCJTP) on community corrections and jail agencies, this study found that correctional organizations that offer COD services differ from agencies that do not. Organizations that respond to the needs of COD offenders tend to be more "service friendly," rank higher on measures of various dimensions of organizational climate that embrace learning and goal achievement, and tend to adopt more innovations, particularly those classified as evidence-based practices. These survey findings indicate that correctional agencies who serve COD offenders are in a better position to be responsive to the changing service needs of the populations, and are more likely to be able to balance public safety and treatment goals. Future steps to develop support environments for COD assessment and treatment services are discussed in light of these findings.     

Violent and disruptive behavior among drug-involved prisoners: relationship with psychiatric symptoms

This study examines the relationship between psychiatric symptoms and violent/disruptive behavior among 192 inmates who participated in prison-based substance abuse treatment. Participants came from two sites able to provide narrative reports of disciplinary actions in the Criminal Justice Drug Abuse Treatment Studies' Co-Occurring Disorders Screening Instrument study. In multivariate logistic models, a lifetime history of thought insertion/control ideation (OR, 11.6; 95% CI, 1.8-75.2), antisocial personality disorder (OR, 3.3; 95% CI, 1.2-8.9), and disciplinary action related to possession of controlled substances or contraband (OR, 4.9; 95% CI, 1.9-12.3) were associated with increased risk for violent or disruptive behavior while in prison, whereas lifetime phobic symptoms (OR, 0.2; 95% CI, 0.1-0.54) and high school graduation (OR, 0.4; 95% CI, 0.2-1.0) were associated with a decreased risk of violence and disruptive behavior in general. We conclude that, among inmates in substance abuse treatment, symptoms that increase risk for violence or disruptive behavior include thought control/insertion ideation and disciplinary infractions related to controlled substances, contraband, or failure to participate in assigned programs, as well a history of antisocial personality disorder.     

The complementarity of apparent and real motion

Summary It is proposed that apparent motion does not parallel real motion. Bather, apparent motion occurs when the off-period is equivalent to angular velocities at which an object in real motion appears blurred. Experimental evidence is reported which supports this view. It suggests that apparent motion serves biologically to extend the range of motion perception beyond that allowed by time-constants early in the visual system.
