Intraclass Correlation Associated with Therapists: Estimates and Applications in Planning Psychotherapy Research

It is essential that outcome research permit clear conclusions to be drawn about the efficacy of interventions. The common practice of nesting therapists within conditions can pose important methodological challenges that affect interpretation, particularly if the study is not powered to account for the nested design. An obstacle to the optimal design of these studies is the lack of data about the intraclass correlation coefficient (ICC), which measures the statistical dependencies introduced by nesting. To begin the development of a public database of ICC estimates, the authors investigated ICCs for a variety outcomes reported in 20 psychotherapy outcome studies. The magnitude of the 495 ICC estimates varied widely across measures and studies. The authors provide recommendations regarding how to select and aggregate ICC estimates for power calculations and show how researchers can use ICC estimates to choose the number of patients and therapists that will optimize power. Attention to these recommendations will strengthen the validity of inferences drawn from psychotherapy studies that nest therapists within conditions.     

Therapist Awareness of Client Resistance in Cognitive-Behavioral Therapy for Generalized Anxiety Disorder

Clients' resistance relates negatively to their retention and outcomes in psychotherapy; thus, it has been increasingly identified as a key process marker in both research and practice. This study compared therapists' postsession ratings of resistance with those of trained observers in the context of 40 therapist–client dyads receiving 15 sessions of cognitive-behavioral therapy for generalized anxiety disorder. Therapist and observer ratings were then examined as correlates of proximal (therapeutic alliance quality and homework compliance) and distal (posttreatment worry severity) outcomes. Although there was reasonable concordance between rater perspectives, observer ratings were highly and consistently related to both proximal and distal outcomes, while therapist ratings were not. These findings underscore the need to enhance therapists' proficiency in identifying important and often covert in-session clinical phenomena such as the cues reflecting resistance and noncollaboration.     

Social Services Workers and Workplace Violence

Researchers and workplace violence experts have cited risk factors that theoretically increase the likelihood that individuals will experience workplace violence. Those include working alone, contact with the public, traveling to dangerous areas, as well as other factors. By the very nature of what social services workers do, many encounter these risk factors on a regular basis. Using national data, trends in workplace violence experienced by social services workers are examined, and comparisons are made between the rates of workplace violence among similar workgroups. Results suggest that social services workers are nearly six times more likely than other workers to experience workplace violence. In the discussion, attention is given to strategies to prevent violence against social services workers.     

Characteristics of Male Batterers in Treatment

Abstract

This article presents information on the characteristics of a clinical population of male perpetrators of intimate partner violence (IPV) court-ordered for batterers' treatment, and how these characteristics co-varied with treatment attrition. The average demographic profile of male batterers in a midwestern treatment program that met present-day treatment guidelines was similar to that found in other studies. In addition, relationship length and status, alcohol/drug use, self-reports of past treatment and mental health issues, and self-report of witnessing or experiencing violence within the home during childhood was also similar. Batterers' self-reports of their own violent behavior were found to vary by data collection technique, with face-to-face interviews eliciting greater admission of violent behavior than paper-and-pencil questionnaires. However, the only predictors of successful treatment outcome were living arrangement at the time of treatment and racial category. Implications of these findings are discussed, and “local effects” program evaluation approaches are suggested.     

Women Experiencing Psychological Abuse: Are They a Homogenous Group?

Dichotomizing women as “abused” versus “not abused” assumes that any psychological maltreatment results in similar outcomes. A national sample of women in conflictual relationships completed an online survey. Women with no incidence (N = 33), the lowest quartile (N = 86), and the top quartile (N = 81) of psychological maltreatment demonstrated significant differences in reactions to the maltreatment, mental health indicators, personality variables, perceived harm, problematic relationship schemas, and response styles. Women with no psychological abuse and women in the lowest quartile produced similar scores that were typically distinct from the top-quartile women. Effective treatment of women with lower amounts of psychological abuse might not require a unique intervention likely necessary for women experiencing much psychological abuse.     

Caring for Carers in the Aftermath of Trauma

The potential impact on psychological well-being of working in the caring professions in the aftermath of trauma and disaster has been recognized for many years, with terms such as burnout, compassion fatigue, and vicarious traumatization coined to describe stress-related conditions. Although prevalent, these conditions do not affect all workers in the field. Various studies have investigated potential risk and protective factors. It is argued that the outcomes of this research should be used to guide practical interventions in the workplace designed to minimize stress-related problems. A framework that incorporates interventions at the primary, secondary, and tertiary prevention levels is outlined, and research investigating the efficacy of interventions at each of these levels is recommended.     

Perceptions of Juvenile Offenders Who Were Abused as Children

Should a history of child abuse be taken into consideration when a juvenile offender is punished? Although some research shows that child abuse is used as a mitigating factor for juvenile offenders (i.e., elicits less punitive sentences), surveys of juvenile court officials reveal that it is considered an aggravating factor. Specifically, in controlled mock jury studies in which child abuse is experimentally manipulated, child abuse elicits less punitive sentences. In contrast, child abuse elicits more punitive sentences in a nonexperimentally controlled environment—the juvenile justice system. This article provides a comprehensive literature review to explain these conflicting bodies of research by considering factors that naturally covary with childhood abuse: chaotic family environment, mental health problems, behavioral problems, and school problems.     

Child Homicide in the City of Los Angeles

SUMMARY

Homicide is the only leading cause of child death which has increased in rank in the past 30 years. This investigation describes the deaths of 0-14 year olds which were classified as homicides by the Los Angeles Police Department from 1980 to 1989. Special focus is given to suspect-to-victim relationship and victim race/ethnicity because of their relevance to prevention and program planning. Family members were suspects in 49.8% of the cases (mother, 14.5%; father, 13.6%; mother's paramour, 8.5%; male and female caretaker, 11.1%; other family members, 2.1%). Few differences emerged among the Black, Hispanic, and non-Hispanic White child victims. Non-Hispanic White victims had the highest proportion (67.7%) and Hispanic victims had the lowest proportion (42.7%) of within-family suspects. Prevention implications include the need to focus on the actions of male caregivers and the observation that the substance and content of prevention programs (e.g., an emphasis on reducing blunt force trauma to young children) can be consistent across race/ethnic groups.     

Resilience to Childhood Abuse and Neglect in College Students

This study examined the prevalence of a history of childhood maltreatment in a college sample and identified the relationship between being maltreated as a child and later college adjustment in men and women. Results indicate that men who had been maltreated in childhood had more resilient outcomes in college than women who had been maltreated in childhood. Negative life events and protective factors acted as mediators in the relationship between childhood maltreatment and college adjustment for women, and protective factors acted as a moderator in the relationship between childhood maltreatment and college adjustment for men.     

Can organizational justice mitigate the negative effects of shift work and fixed-term employment?

The present study examined whether organizational justice moderates the association of shift work and employment type with patient-related stress, stress symptoms, and musculoskeletal symptoms. Cross-sectional survey data from 1270 Finnish female elderly care staff aged 18–69 years was used. Analyses of covariance were used to examine the associations adjusted for age,marital status, education, and tenure. Organizational justice was associated with lower levels of patient-related stress, stress symptoms, and musculoskeletal symptoms. Organizational justice mitigated stress symptoms related to working night shift and three shifts. In addition, organizational justice mitigated the patient-related stress associated with working on fixed-term contracts. Organizational justice was also able to alleviate musculoskeletal symptoms associated with working on permanent contracts. Thus, we found evidence for organizational justice being able to mitigate the negative effects of shift work and employment type. Promoting organizational justice in organizations with shift work and lots of fixed-term contracts is of importance.
