Abstract

What the literature reports that adolescents need within their parent-adolescent relationships, as well as what adolescents with serious emotional disturbances may experience within their parent-adolescent relationships are discussed. A framework for providing parent-adolescent group intervention for psychiatrically hospitalized adolescents and their parents to promote positive interaction and co-occupation are provided. Summaries of the parent-adolescent activity group experiences of three families are provided to illustrate how different adolescent psychiatric issues and family dynamics might be addressed in a parent adolescent activity group.  相似文献

In this paper we describe psychotherapeutic work carried out in a paediatric hospital to illustrate the important contribution of a psychoanalytically-oriented approach in a hospital context. The work concerns an adolescent boy who had undergone several surgical operations with the result that some of his natural orifices were obstructed and artificial ones had to be created. He was referred to us because he refused pharmacological and rehabilitative treatment necessary prior to further surgery and his eventual recovery. The boy's experience of loss of control of his life and the more primitive anxieties of not feeling safely contained in his physical and psychic skin emerged and were worked through in the psychotherapeutic relationship. The parallel work with medical staff reduced the risk of splitting and acting out by the patient and professionals. The approach adopted enabled this boy to resume his medical treatment and his developmental process.  相似文献

Attentional interference by threat is associated with PTSD, but the mechanisms of this relationship remain unclear. Attentional interference might be related to increased use of maladaptive thought control strategies, such as suppressing unwanted thoughts (thought suppression) or replacing threatening thoughts with everyday concerns (worry), which increase PTSD risk. Conversely, attentional interference might be associated with reduced use of adaptive strategies, such as talking about threatening thoughts (social control), which decrease PTSD risk. This study tested if thought control strategies mediate the relationship between attentional interference and PTSD. Sixty-one male Vietnam-era veterans completed measures of PTSD symptoms and thought control strategies. Participants also completed a Visual Search Task measuring attentional interference, which required participants to identify a target letter string among a group of threat or neutral words. Attentional interference by threat was related to PTSD symptoms, and mediation analyses revealed significant indirect effects of attentional interference through thought suppression and worry. Attentional interference was related to re-experiencing and avoidance, but not hyperarousal, symptom clusters. Thought suppression was a unique mediator for re-experiencing, whereas thought suppression and worry both mediated the relationship with avoidance. These results offer evidence for maladaptive thought control strategies as a mechanism linking attentional biases for threat to PTSD.  相似文献

The effectiveness of a behaviorally based day treatment program for young children diagnosed with Pediatric Bipolar Disorder (PBD) was evaluated using pretreatment and posttreatment mean scores from the Child Behavior Checklist (CBCL). Data were evaluated in aggregate and using the clinically significant change method for children diagnosed with PBD, Attention Deficit Hyperactivity Disorder (ADHD), Oppositional Defiant Disorder (ODD), Adjustment Disorder, and no diagnosis/clinical and subclinical groups. Significant effects were found for all groups except the no diagnosis/subclinical group on the Internalizing scale and for all groups on the Externalizing scale. Clinically significant change was supported for the PBD, ADHD, ODD, and Adjustment Disorder groups. Implications and limitations of the study are discussed.  相似文献

Veterans from the conflicts in Afghanistan (Operation Enduring Freedom; OEF) and Iraq (Operation Iraqi Freedom; OIF) have reported elevated rates of alcohol consumption, and greater depression and posttraumatic stress disorder (PTSD) symptoms are associated with increased alcohol use. Presence of a spouse/partner, which has been associated with reduced drinking, may buffer the relationship between mental health symptoms and alcohol consumption. To examine this hypothesis, the current study utilized baseline survey data from OEF/OIF veterans (N = 325) enrolled in a brief alcohol intervention. Spouse/partner presence moderated the relationship between depression symptoms and alcohol consumption such that depression was positively associated with drinking for veterans without a spouse/partner. Exploratory analyses indicated that the relationship between depression and alcohol use may be particularly salient for veterans without a spouse/partner and a lower number of deployments. Spouse/partner presence did not moderate the relationship between PTSD symptoms and alcohol consumption. Implications of the findings are discussed.  相似文献

Posttraumatic Stress Disorder (PTSD) is associated with difficulties in intimate relationships, with most prior research examining associations with continuous, single-dimension, and often-unstandardized measures of general relationship quality or aggression. Standardized, well-normed assessments that include multiple couple problem areas could provide more precise information about the presence and specific nature of clinically significant concerns in patient care settings. This investigation aimed to replicate findings regarding increased difficulties in relationship functioning among Operations Enduring and Iraqi Freedom Veterans with PTSD and their romantic partners, specifically using a standardized assessment that permits identification of cases of clinically significant general couple distress and difficulties across multiple problem areas. We compared 32 male Veterans with PTSD and 33 without PTSD, and their romantic partners on reports of several problem areas using the revised Marital Satisfaction Inventory (MSI-R). All participants underwent structured diagnostic interviewing. PTSD couples reported clinically significant levels of relationship distress several times more frequently than comparison couples, both for general distress and across all specific problem areas (e.g., aggressive behavior, quality of leisure time together, sexual functioning, conflicts about finances and child rearing). The most notable problem areas for PTSD couples were affective and problem-solving communication. These results replicate associations of PTSD with general couple discord and multiple specific areas of couple difficulties and extend them by documenting the clinical severity of these problems. Mental health providers may consider incorporating standardized couple assessments into their evaluations of Veterans’ functioning. Couple therapies may consider using such measures to prioritize targets for treatment.  相似文献

The Institute of Medicine has stressed the need for evaluations of evidence-based treatments (EBTs) for posttraumatic stress disorder (PTSD) among active duty service members (AD) using a variety of evaluation approaches (Institute of Medicine, 2012). The current study examined the clinical files of 134 service members who completed treatment for PTSD using either prolonged exposure (PE) or cognitive processing therapy at an outpatient clinic. At the completion of each session, therapists made a clinical rating as to whether or not the session was protocol adherent. The total number of treatment sessions and the proportion of sessions rated as being protocol adherent were calculated. Multi-level models estimated the change in patient PTSD and other psychological symptoms over time as a function of clinician-rated protocol adherence and total number of sessions. Approximately 65% of clinic encounters were rated by therapists as being protocol adherent. Significant reductions in PTSD and psychological symptoms were associated with protocol adherence, and this was particularly true for patients who began treatment above clinical thresholds for both PTSD and other psychological symptoms. However, as the number of sessions increased, the impact of protocol adherence was attenuated. Patient characteristics, including gender, ethnicity, and co-morbidity for other psychiatric disorders were not related to symptom change trajectories over time. These findings suggest that protocol adherence and efficiency in delivery of EBTs for the treatment of PTSD with AD is critical.  相似文献

The current study’s goal was to provide a comprehensive review of current subthreshold posttraumatic stress disorder (PTSD) rates among U.S. military veterans and service members. PubMed, PsycInfo, ProQuest, Web of Knowledge, Google Scholar, and any relevant articles’ reference lists identified studies of subthreshold PTSD in the U.S. military. Search terms included PTSD in combination with partial, subthreshold or sub-threshold, subsyndromal or sub-syndromal, subclinical or sub-clinical, and military or veteran. Sixteen articles met criteria for review. Current subthreshold PTSD rates ranged from 2.3% to 22.3%, with a weighted mean rate of 7.6%. Definitional variation within and across the “below threshold” terms produced some variability in rates reported. Few studies consistently reported on impairment and comorbidity in the subthreshold PTSD population. Variability of current subthreshold PTSD rates may be due to methodological issues such as sampling methods, sample sizes, and how below threshold PTSD was assessed and defined. Based on our findings, we provide a number of recommendations that can be used to inform future research of subthreshold PTSD among U.S. military veterans and service members. These recommendations include having a standardized term and definition, determining how to more properly assess subthreshold PTSD symptomatology, clarifying subthreshold PTSD diagnostic stability, and identifying appropriate sampling methods.  相似文献

Anger and aggression are common combat-related behavioral health problems. The impact of combat on anger and aggression appears to be largely attributable to symptoms of posttraumatic stress disorder (PTSD). Factors that moderate the purported pathway from combat to anger and aggression are poorly understood. We examined the conditional direct and indirect associations of combat exposure with self-reported anger and aggression using survey data collected from 592 U.S. Soldiers during a combat deployment in Afghanistan. Unit morale was examined as a moderator between combat exposure and PSTD symptoms, as well as the indirect association of combat exposure with anger and aggression via PTSD symptoms, controlling for depression symptoms. Results indicated that unit morale was negatively correlated with PTSD symptoms and self-reported anger and aggressive behaviors. Perceptions of unit morale moderated the direct association of combat exposure with PTSD symptoms. Unit morale also moderated the indirect association of combat exposure with anger and aggression through PTSD symptoms. Unit morale moderated the association of combat exposure with anger and aggression during combat operations by putatively mitigating the deleterious effect of combat on stress-related symptoms. The impact of policy and leadership on soldier and unit morale should be carefully considered given its protective role during combat operations.  相似文献
