It has been hypothesized that some types of personality disorders tend to remit with age whereas others may become more prominent. The present study determined the prevalence and nature of 13 personality disorders with a self-report inventory (Coolidge Axis II Inventory) in an older group of chronically mentally ill inpatients (N = 30, mean age = 63 years) and a younger group of similar patients (N = 30, mean age = 39 years). All patients met DSM-IV criteria for either Schizophrenia, Schizoaffective Disorder, Bipolar Disorder, or recurrent severe Major Depression with psychotic features. The prevalence rate of personality disorders was high for both groups: 58% for the older sample and 66% for the younger group. The younger group was more likely to be diagnosed Antisocial, Borderline, Passive-Aggressive, Sadistic, and Schizotypal, but the groups were not different in the rates of Obsessive-Compulsive Disorder. This study supports the hypothesis that some personality disorders remit with age. However, no evidence was found to suggest that other personality disorders become more prominent in older adult psychiatric populations. Suggestions for future research are offered.  相似文献

The present study was designed to gather validity data on the Devereux Scales of Mental Disorders (DSMD) for distinguishing among children and adolescents with Attention-Deficit/Hyperactivity Disorder (ADHD; N = 32), Conduct Disorder (CD; N = 34), or no clinical diagnosis (NC; N = 65). Three types of indicators were compared: (a) DSMD scale, composite, and total scores, (b) the number of ADHD or CD-related items endorsed, and (c) diagnostic efficiency statistics (e.g., sensitivity, positive and negative predictive power). The clinical groups did not differ significantly from each other, but both were significantly higher than the NC group on all DSMD scales. Moreover, there were significant differences between the ADHD and the CD groups on the number of respective ADHD and CD-related items endorsed. A cut-off of seven to eight items yielded the best discrimination between the two diagnostic groups. Diagnostic efficiency statistics indicate that the DSMD may be effective at differentiating between similar disruptive behavior disorders.  相似文献

Maternal reports about infant sleep care and ideas about the causes of awakening were obtained from telephone interviews with 104 middle class primiparae when their infants were 1 month and 1 year old. These reports were compared with their expectations about infant sleep before the birth of their child. It was found that most of the mothers were willing to ‘help’ their infants fall asleep, with 19 different kinds of techniques being spontaneously mentioned. Most of the techniques involved physical contact. The changes in technique from before birth to the end of the first year of life mainly concerned a decrease in the use of techniques involving holding the infant in the arms. From 1 month to 1 year, there was a decrease in rocking techniques, while at 1 year the use of a (bottle) feeding technique and taking the child into the parents' bed became apparent. The reasons mothers gave for infant awakenings varied from 1 month to 1 year. At 1 year, the most frequent reason was that the infant has ‘sufficient sleep’. Mothers' representations before the infant birth did not overlap with representations and reports of sleep handling after birth. Mothers were willing to apply and use a great variety of caring techniques that they perceived to be adjusted to the individual needs of their child. © 1998 John Wiley & Sons, Ltd.  相似文献

Exposure-based interventions are a core ingredient of evidence-based cognitive-behavioral treatment (CBT) for anxiety disorders, posttraumatic stress disorder (PTSD), and obsessive-compulsive disorder (OCD). However, previous research has documented that exposure is rarely utilized in routine care, highlighting an ongoing lack of dissemination. The present study examined barriers for the dissemination of exposure from the perspective of behavioral psychotherapists working in outpatient routine care (N = 684). A postal survey assessed three categories of barriers: (a) practicability of exposure-based intervention in an outpatient private practice setting, (b) negative beliefs about exposure, and (c) therapist distress related to the use of exposure. In addition, self-reported competence to conduct exposure for different anxiety disorders, PTSD, and OCD was assessed. High rates of agreement were found for single barriers within each of the three categories (e.g., unpredictable time management, risk of uncompensated absence of the patient, risk of decompensation of the patient, superficial effectiveness, or exposure being very strenuous for the therapist). Separately, average agreement to each category negatively correlated with self-reported utilization of exposure to a moderate degree (-.35 ≤ r ≤ -.27). In a multiple regression model, only average agreement to barriers of practicability and negative beliefs were significantly associated with utilization rates. Findings illustrate that a multilevel approach targeting individual, practical, and systemic barriers is necessary to optimize the dissemination of exposure-based interventions. Dissemination efforts may therefore benefit from incorporating strategies such as modifying negative beliefs, adaptive stress management for therapists, or increasing practicability of exposure-based interventions.  相似文献

The objective of this study was to use qualitative methodology to tailor and refine an existing smoking cessation intervention for the population of people who use cigarettes and are diagnosed with schizophrenia, schizoaffective, or psychotic disorder. Successive cohort design methodology was used to iteratively modify the treatment in response to qualitative participant, therapist, and consultant feedback on the intervention. Qualitative methodology for participant feedback included analysis of semistructured interviews with participants, visualization of app utilization data, and stakeholder feedback from study therapists and consultants. Using the successive cohort design, a tailored multicomponent mobile health smoking cessation intervention was developed. The intervention included mobile contingency management (i.e., financial compensation for confirmed abstinence from smoking), pharmacotherapy for smoking cessation, cognitive-behavioral counseling sessions, and the Stay Quit app for relapse prevention. Two cohorts (N = 13) were completed in the study; after each cohort, the treatment protocol was revised. The intervention is described, as well as the qualitative findings from each cohort and subsequent changes made to the intervention based upon patient and provider feedback. Metrics of patient engagement included treatment adherence (40% in Cohort 1 and 63% in Cohort 2). Both participants and therapists reported that the intervention was helpful. Over one third of participants self-reported abstinence at posttreatment. Since qualitative methodology is often underutilized in mental health treatment development, this study demonstrates the utility of the successive cohort design for treatment development of behavior change interventions for at-risk, vulnerable populations.  相似文献

Individuals with social anxiety disorder (SAD) have difficulties in their romantic relationships, including decreased satisfaction and intimacy, but the reasons for these difficulties are poorly understood. Because fear of negative evaluation is a cardinal feature of SAD, perceived criticism from a romantic partner may play a central role in socially anxious individuals’ relationships. In the present study, we compared levels of perceived, expressed, and observed criticism and reactions to criticism among individuals with SAD and their partners (n = 21), individuals with other anxiety disorders and their partners (n = 35), and couples free of psychopathology (n = 30). Participants rated both global criticism and criticism during a 10-minute problem-solving task, which was also coded for criticism by observers. Individuals with anxiety disorders showed elevated levels of interaction-specific perceived criticism, expressed criticism, and upset and stress due to criticism relative to normal controls; they also reported that the interaction was more stressful. However, there were no group differences on global measures of criticism, and the two anxious groups did not differ on any measures. Findings suggest that the high levels of criticism anxious individuals perceive and their corresponding negative reactions to criticism, though not specific to SAD, may account for some of the relationship difficulties that have been identified in SAD. Results also indicate that anxious individuals may contribute to their relationship difficulties by being highly critical themselves. Overall, our findings point to the need for a clinical focus on decreasing perceived criticism among individuals with anxiety disorders.  相似文献

The Good Behavior Game (GBG) is a classroom management system that employs an interdependent group contingency, whereby students work as a team to win the game. Although previous anecdotal data have suggested that this arrangement may promote prosocial behavior, teachers may have concerns about its fairness and potential to evoke negative peer interactions (especially toward students who break the rules). We evaluated disruptive behaviors and social interactions during the GBG in a secondary classroom for students with emotional and behavioral disorders, as well as in a primary classroom for students with mild developmental disabilities. Results indicate that the GBG reduced disruptive behaviors; further, negative peer interactions decreased and positive interactions increased when the game was being played. Social validity results indicate that the majority of students thought the interdependent group contingency was fair.  相似文献

Different clinical subtypes of Parkinson’s disease (PD) have long been recognized. Recent studies have focused on two PD subtypes: Postural Instability and Gait Difficulty (PIGD) and Tremor Dominant (TD). PIGD patients have greater difficulties in postural control in relation to TD. However, knowledge about the differences in reactive adjustment mechanisms following a perturbation in TD and PIGD is limited. This study aimed to compare reactive postural adjustments under unexpected external perturbation in TD, PIGD, and control group (CG) subjects. Forty-five individuals (15 TD, 15 PIGD, and 15 CG) participated in this study. Postural perturbation was applied by the posterior displacement of the support surface in an unexpected condition. The velocity (15 cm/s) and displacement (5 cm/s) of perturbation were the same for all participants. Center of pressure (CoP) and center of mass (CoM) were analyzed for two reactive windows after the perturbation (0–200 ms and 200–700 ms). The Bonferroni post hoc test indicated a higher range of CoP in the PIGD when compared to the CG (p = 0.021). The PIGD demonstrated greater time to recover the stable posture compared to the TD (p = 0.017) and CG (p = 0.003). Furthermore, the TD showed higher AP-acceleration peak of CoM when compared to the PIGD (p = 0.048) and CG (p = 0.013), and greater AP-acceleration range of CoM in relation to the CG (p = 0.022). These findings suggest that PD patients present worse reactive postural control after perturbation compared to healthy older individuals. CoP and CoM parameters are sensitive to understand and detect the differences in reactive postural mechanisms in PD subtypes.  相似文献

IntroductionPostural instability during walking and tripping over obstacles are the main causes of falls in people with Parkinson’s disease (PD). Preliminary limited evidence suggests that the length of the prospective follow-up period affects falls prediction in PD, with shorter periods leading to more accurate prediction. Thus, the primary aim of the present study was to test the performance of center of pressure (CoP) variables during obstacle crossing to predict fall risk in people with PD during subsequent periods of four, six, and 12 months. We also compared CoP variables during obstacle crossing between fallers and non-fallers.MethodsForty-two individuals with PD, in mild to moderate stages, completed the baseline obstacle crossing assessment and reported falls for 12 months. Participants walked at their self-selected pace and were instructed to cross an obstacle (half knee height) positioned in the middle of an 8-m long pathway. A force platform was used to analyze CoP parameters of the stance phase of the trailing limb (most affected limb). The ability of each outcome measure to predict fall risk at four, six, and 12 months was assessed using receiver operating characteristic curve analyses.ResultsTen individuals (23.8%) were considered fallers at four months, twelve individuals (28.5%) at six months, and twenty-one individuals (50%) at 12 months. CoP amplitude and CoP velocity in the mediolateral direction significantly predicted fall risk at four, six, and 12 months. As judged by the area under the curve, mediolateral CoP velocity showed the best performance at four months, while mediolateral CoP amplitude showed the best performance at six months. Fallers presented greater values of mediolateral CoP velocity and amplitude than non-fallers.ConclusionThese findings suggest that mediolateral CoP velocity and amplitude during obstacle crossing might be useful to predict fall risk in people with PD. Therefore, larger studies are encouraged.  相似文献
