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

The effectiveness of a parenting program was examined with an Australian sample regarding improved parent knowledge, parental sense of competence, and child behavior. One hundred and sixteen parents and their children were randomly assigned to three conditions: a two-session group based intervention, a two-session self-administered individual intervention, or to a waitlist control group. Across both treatment modalities results reveal a significant increase in parental satisfaction, efficacy, and a reduction in child problem behavior. Improvements were maintained at 3-months follow-up. Results indicate the individual self-administered format enhanced treatment gains relative to the group format. 相似文献

A group of children with Attention Deficit Hyperactivity Disorder (ADHD) was compared to children with other behavior and emotional problems. All the participants participated together in 20 weekly sessions for 1 academic year. The participants were assessed with three questionnaires on three different occasions: before the beginning of the group, at the completion of the group, and 1 year after the completion of the group. The results showed that the children indicated improvement in two behavior domains while their parents indicated improvement in the children's behavior in five domains. The most striking improvement was reduction of anxiety. 相似文献

Abstract The clinical and psychosocial effects of immediate penile prosthesis implantation at the time of radical prostatectomy (RP) were investigated in 97 consecutive patients and 68 partners. Prosthesis recipients reported more frequent sexual contact, fewer marital problems and slightly fewer sexual functioning problems than the RP-alone patients. There were no group differences on any sociodemographic characteristics, on disease recurrence, on physical and psychosocial functioning, or on reported depression. Patients who chose the prosthesis did, however, evidence less of a link between depression and functional limitations and between depression and marital problems. They also had lower levels of agreement with their partners in reporting their own depression, as compared to the patients who opted for RP surgery alone. We conclude that the penile prosthesis was associated with an increased frequency of sexual contact, a reduction in reported marital problems, and stylistic differences between the two patient groups in dealing with affect. 相似文献

The current studies examine proximal and distal mortality salience effects on the willingness to engage in health-promoting activities and explore the roles of age and self-esteem. In Study 1, 164 participants completed a self-esteem scale, were assigned to a mortality salience or a neutral condition, and then completed a scale, tapping their willingness to engage in health promoting activities. Findings revealed that in the proximal mode, mortality salience led the young and middle-aged adults to report higher willingness to promote health behaviors, whereas older adults tended to show a lower willingness to promote their health compared to the control condition. In Study 2, a total of 251 participants completed the same series of questionnaires, including a distracting task immediately after the mortality salience manipulation. Findings revealed that, in the distal mode, whereas death reminders did not affect young adults, mortality salience led middle-aged participants to express higher willingness to conduct health-promoting behaviors than in a control condition. The mortality salience induction did not affect older adults with high self-esteem, but led low self-esteem individuals to report higher willingness to promote their health. The differences between the reactions of the different age groups in both the defense modes are discussed in view of the terror management theory. 相似文献

We sought to determine whether different social, psychological, emotional, and physiological experiences associated with quitting smoking related to people's satisfaction with cessation systematically, and whether the strength of the relations changes at different points during the cessation process and for different people (e.g., optimists). Using data from smokers enrolled in a cessation program, we used mixed models to assess the average longitudinal relation between people's experiences and satisfaction measured at seven time points and whether the relations were moderated by key variables. Eight of nine experiences were related to people's satisfaction (ps < 0.05) and the models accounted for 39–44% of the within-person variance in satisfaction. Current smoking behavior was more strongly related to people's satisfaction during their early efforts to quit, whereas some experiences (e.g., feedback from others) had a stronger relation with satisfaction during people's later efforts to quit or maintain abstinence (ps < 0.05). Individual differences in optimism and prior cessation experience moderated some of the relations (ps < 0.05). The findings mark the first evidence of factors that might influence how people determine their satisfaction with smoking cessation. The implications for tailoring interventions and potentially increasing the likelihood that people maintain abstinence are discussed. 相似文献

The purpose of this study was to explore whether sedentary behavior cognitions explain physical activity (PA) intention and behavior when integrated within the theory of planned behavior framework (TPB). A random community sample of 206 adults and a sample of 174 undergraduate students completed measures of the TPB pertaining to PA and four popular leisure-time behaviors (TV viewing, computer use, sedentary hobbies, and sedentary socializing) and an adapted Godin Leisure-Time Exercize Questionnaire (community sample = cross-sectional, undergraduate sample = 2-week prospective). Results using ordinary least squares regression provided evidence that TV viewing intention explains additional variance in PA behavior, and affective attitude (community sample) and perceived behavioral control (undergraduate sample) towards TV viewing explains additional variance in PA intention even after controlling for PA-related TPB constructs. These results underscore the potential value of adding sedentary control interventions in concert with PA promotion. 相似文献

A reliable two-factor instrument measuring appearance motivation attitudes for sun protection was developed using a longitudinal sample of beachgoers. At baseline, data on sun protection and appearance motivation attitudes were collected on 2324 individuals. Principal components analyses (PCA) indicated a two-factor solution measuring attitudes toward tan attractiveness and skin protection with only 2 items loading on the skin protection factor. At 12-months, the instrument was revised and shortened but including 3 new skin protection items. Split-half analyses were conducted to further refine and develop the instrument. PCA on half of the sample revealed a two-factor solution, which was confirmed using structural equation modeling on the remaining half. This resulted in a two correlated-factor, 10-item measure. Each factor was summed to create two scales. Both scales were internally consistent and demonstrated good external validity, correlating with sun protection specific Transtheoretical model variables. The tan attractiveness attitudes scale significantly improved prediction of sun protection outcomes over 24 months, over and above TTM variables. 相似文献

The magnitude and predictors of longitudinal behavioral change are reported in a cohort of homosexual men at risk for AIDS. Self-reports of sexual behavior were obtained at two points in time separated by an interval of approximately six months. These self-reports were used to construct both dichotomous and continuous measures of changes in behavior consistent with reduction in the transmission of the AIDS virus (HIV). Although there was considerable variability in behavior. mean changes were consistently in the desired direction. Avoidance of anonymous sexual partners, monogamy, and modification of receptive anal sex to reduce exposure to semen by condom use or withdrawal prior to ejaculation appeared to be especially important in this cohort. Both multiple linear regression and multiple logistic regression were used to examine the relationship between a model of health behavior and these outcomes. Variables examined included knowledge of AIDS. perceived risk of AIDS. the perceived efficacy of behavior in reducing AIDS risk, difficulties with sexual impulse control, belief in biomedical technology to provide a prevention or cure, social norms supportive of behavioral change, and gay network affiliation. Of all these factors, only the availability of supportive peer norms was consistently, significantly and positively related to multiple measures of outcome. Differences between these analyses and longitudinal analyses reported elsewhere are discussed. These results suggest the policies regarding HIV antibody testing should be developed cautiously. taking account of the failure of a sense of risk to predict subsequent behavioral change. They also emphasize the important role of gay organizations in developing social norms supportive of behavioral risk reduction. 相似文献

The primary purpose of this study was to investigate whether the theory of planned behavior (TPB) mediated the relationship between dialectical thinking and health behaviors. A sample of 285 undergraduates was tested with a dialectical thinking styles scale, health promoting lifestyle profiles, and TPB questionnaires. Structural equation modeling was used for data analysis. Results indicated that all the three dimensions of thinking styles (belief in the connection, acceptance of change, and acceptance of contradiction) exerted significant effects on TPB constructs. Specifically, the connection and the change dimensions had positive effects on health behaviors mediated by TPB, whereas the contradiction dimension had a negative effect. Model 2 showed a satisfactory fit, demonstrating the influential pathways between dialectical thinking and health behaviors. Implications in issues of health promotion and future research are discussed. 相似文献
