Effectiveness of a Multiple Family Group Intervention for Juvenile First Offenders in Reducing Parent Stress

Parenting practices are major influences on incidents of juvenile delinquency. Stress experienced by parents of children with behavioral problems is a leading contributor to parenting practices. We investigated the extent to which parental stress was reduced by participation in an established multiple group family intervention, the Family Solutions Program, developed to reduce recidivism among juvenile offenders. We also examined parent stress by gender, ethnicity, dropout rates, intervention benefits at 3-month follow-up, single- versus two-parent households, and across dimensions of family functioning and parent-adolescent communication. Parents reported greater levels of parent stress than non-clinical parents prior to intervention. Parental stress did diminish in response to intervention, but not until follow-up to intervention completion. No differences were found on initial parent stress level between completers and non-completers of the intervention or between parent stress and gender or ethnicity of the parent; however, single-parent household was associated with significantly higher levels of parent stress. Family functioning was significantly negatively correlated with parental stress. Finally, open communication between juvenile first offenders and their parents improved significantly in response to the intervention both at post-intervention and at follow-up.     

A Mixed‐Methods Evaluation of Intensive Trauma‐Focused Programming

This study investigated the magnitude of treatment effect and clients' perceptions of change during a 10‐week intensive outpatient program (IOP) for individuals with posttraumatic stress disorder. Participants were 48 adults (30 women, 18 men) with a mean age of 43.48 years (SD = 12.16) who were predominantly European American (72.9%, n = 35). Results of a mixed‐methods sequential explanatory design indicated that the IOP was strongly associated with decreased psychological symptom severity and increased relational health among participants over time.     

A Dimensional Model of Psychopathology Among Homeless Adolescents: Suicidality,Internalizing, and Externalizing Disorders

The present study examined associations among dimensions of suicidality and psychopathology in a sample of 428 homeless adolescents (56.3% female). Confirmatory factor analysis results provided support for a three-factor model in which suicidality (measured with lifetime suicidal ideation and suicide attempts), internalizing disorders (assessed with lifetime diagnoses of major depressive episode and post-traumatic stress disorder), and externalizing disorders (indicated by lifetime diagnoses of conduct disorder, alcohol abuse, and drug abuse) were positively intercorrelated. The findings illustrate the utility of a dimensional approach that integrates suicidality and psychopathology into one model. Kevin A. Yoder and Susan L. Longley made equal contributions to this paper.     

Horizontal Plane Head Stabilization During Locomotor Tasks

Frequency characteristics of head stabilization were examined during locomotor tasks in healthy young adults (N = 8) who performed normal walking and 3 walking tasks designed to produce perturbations primarily in the horizontal plane. In the 3 walking tasks, the arms moved in phase with leg movement, with abnormally large amplitude, and at twice the frequency of leg movement. Head-in-space angular velocity was examined at the predominant frequencies of trunk motion. Head movements in space occurred at low frequencies (< 4.0 Hz) in all conditions and at higher frequencies (> 4.0 Hz) when the arms moved at twice the frequency of the legs. Head stabilization strategies were determined from head-on-trunk with respect to trunk frequency profiles derived from angular velocity data. During natural walking at low frequencies (< 3.0 Hz), head-on-trunk movement was less than trunk movement. At frequencies 3.0 Hz or greater, equal and opposite compensatory movement ensured head stability. When arm swing was altered, compensatory movement guaranteed head stability at all frequencies. Head stabilization was successful for frequencies up to 10.0 Hz during locomotor tasks Maintaining head stability at high frequencies during voluntary tasks suggests that participants used feedforward mechanisms to coordinate head and trunk movements. Maintenance of head stability during dynamic tasks allows optimal conditions for vestibulo-ocular reflex function.     

The Relationship of Impulse to Response Timing Error

This paper examines the relationship between response impulse and timing error in 200 msec discrete timing responses over a range of movement velocities and system masses. The results from two experiments showed that variable timing error decreased as both movement velocity and the mass of the system to be moved increased. The variability of force proportional to force (measured either as impulse or peak force) decreased curvilinearly as force output increased. The correlations between each of these parameters and variable timing errors, calculated on a group mean basis, ranged between .91 and .95. The ability to predict the movement time outcome of each individual trial from impulse-related parameters was considerably reduced, although the relationship between the various kinematic and kinetic parameters did strengthen as the movement velocity approached maximum. Collectively, the findings show that size of impulse is related to movement timing error, although it is premature to argue that impulse variability is a causal agent of timing error.     

Error Detection and Correction in a Structured Movement Task

Error-detection and error-correction experiments were conducted to examine the assumption that organizational processes play an important role in motor learning and control. During the initial phase of each experiment, the sensory aspects of five movements were held constant while the organizational structure (sequential vs. random) of the movements was varied. In the learning phase of both experiments, the effect of organization produced increased reproduction accuracy for the structured movement sequences compared to those that were random. This benefit of organization carried over into the error detection and correction parts of the experiments where it was shown that improved error detection and correction capabilities were assisted by the manner in which the movements were presented. The importance of cognitive processes is discussed in terms of past and contemporary accounts of motor learning and control.     

Category inference as a function of correlational structure, category discriminability, and number of available cues

Two experiments investigated category inference when categories were composed of correlated or uncorrelated dimensions and the categories overlapped minimally or moderately. When the categories minimally overlapped, the dimensions were strongly correlated with the category label. Following a classification learning phase, subsequent transfer required the selection of either a category label or a feature when one, two, or three features were missing. Experiments 1 and 2 differed primarily in the number of learning blocks prior to transfer. In each experiment, the inference of the category label or category feature was influenced by both dimensional and category correlations, as well as their interaction. The number of cues available at test impacted performance more when the dimensional correlations were zero and category overlap was high. However, a minimal number of cues were sufficient to produce high levels of inference when the dimensions were highly correlated; additional cues had a positive but reduced impact, even when overlap was high. Subjects were generally more accurate in inferring the category label than a category feature regardless of dimensional correlation, category overlap, or number of cues available at test. Whether the category label functioned as a special feature or not was critically dependent upon these embedded correlations, with feature inference driven more strongly by dimensional correlations.     

Downsizing in britain and its effects on survivors and their organizations

Abstract

In this paper, we examine the psychological effects of downsizing and redundancy on those remaining within organizations after large-scale redundancy programs. While there have been a number of studies of this type in the recent past, our task is to explore two separate studies which have investigated this phenomena. The first study explores the impact of redundancy in a recently privatized organization in the UK. This, we argue, is a particularly fertile area of study given the radical changes that have affected organizations in the UK that have been subjected to privatization. The results stem from an exploratory and qualitative case study which takes an individual perspective. The second study discussed in this paper explores the results of a survey conducted in the UK that examines the implications of change in both the public and private sector organizations. This survey takes a quantitative look at the implications of redundancy from an organizational perspective. By investigating these two studies, our research explores the impact of redundancy on two levels—the individual level and the organizational level. First, we examine the emotional, attitudinal and behavioral effects of redundancy on survivors and the resultant implications for management: in particular the changing role of line managers where delayering and redundancy has taken place. Second, we explore the impact of redundancy on the organization in terms of organizational morale, motivation, organizational loyalty and job security where redundancy has and has not been used as a method of downsizing.     

The Role of Peers in the Linkages Between Harsh Parenting and Mental Health Outcomes Among Adolescents from Families At-Risk

Harsh parenting is associated with adolescent mental health concerns. Peer relationships also importantly influence adolescent mental health outcomes. Although the direct associations between harsh parenting, peer relationships, and adolescent outcomes have been empirically established, less is known about the extent to which peer relationships mediate the associations between harsh parenting and adolescent outcomes. This study tested the links between harsh parenting, peer relationships, and adolescent outcomes among families at-risk for child maltreatment. With a sample of caregivers and adolescents (n = 218), the results of mediation analyses indicated that peer aggression partially mediated the pathway between harsh parenting and externalizing symptoms of both females and males. Additionally, peer rejection partially mediated the links between harsh parenting and internalizing symptoms of both females and males and peer rejection also was a partial mediator of male externalizing symptoms.
