Social support, positive states of mind, and HIV treatment adherence in men and women living with HIV/AIDS.

Numerous studies have linked social support to better medication adherence among illness groups, but few have examined potential mechanisms for this relationship. Relationships were examined between social support, depression, positive states of mind (PSOM), and medication adherence among HIV positive men who have sex with men (n = 61) and women (n = 29) on highly active antiretroviral therapy. Depression and PSOM were evaluated as potential mediators of the relationship between support and adherence. Cross-sectional data showed that greater social support and PSOM related to better adherence whereas higher depression scores related to nonadherence. PSOM partially mediated the relationship between social support and adherence. PSOM may be an important mechanism through which social support is related to better medication adherence in this population.     

Complete Axiomatizations for Reasoning about Knowledge and Branching Time

Sound and complete axiomatizations are provided for a number of different logics involving modalities for the knowledge of multiple agents and operators for branching time, extending previous work of Halpern, van der Meyden and Vardi [to appear, SIAM Journal on Computing] for logics of knowledge and linear time. The paper considers the system constraints of synchrony, perfect recall and unique initial states, which give rise to interaction axioms. The language is based on the temporal logic CTL*, interpreted with respect to a version of the bundle semantics.     

Exposure therapy for PTSD delivered to veterans via telehealth: predictors of treatment completion and outcome and comparison to treatment delivered in person

Recent research has focused on the effectiveness of evidence-based psychotherapy delivered via telehealth services. Unfortunately to date, the majority of studies employ very small samples and limited predictor and moderator variables. To address these concerns and further replicate and extend the literature on telehealth, the present study investigated the effectiveness of 12-session exposure therapy delivered either via telehealth (n = 62) or in person (n = 27) in veterans with posttraumatic stress disorder (PTSD). Findings demonstrated that although older veterans and Vietnam veterans were more likely to complete the telehealth treatment, telehealth findings were not influenced by patient age, sex, race, combat theater, or disability status. Exposure therapy delivered via telehealth was effective in reducing the symptoms of PTSD, anxiety, depression, stress, and general impairment with large effect sizes. Interestingly, exposure therapy via telehealth was less effective than exposure therapy delivered in person; however, lack of random assignment to condition limits conclusions of differential effectiveness. Overall, these findings support the utility of telehealth services to provide effective, evidence-based psychotherapies.     

Labour Market Discrimination: the Lived Experiences of English-Speaking Caribbean Immigrants in Toronto

The study examined the lived experiences of immigrants in Toronto from Jamaica, Guyana and Trinidad and Tobago, with emphasis on their perceptions and experiences of labour market discrimination. The study employs a qualitative methodology and adopts a critical policy research framework which included a series of in-depth interviews. Based on the central argument that there is a disjuncture between the human capital model used at the policy level and the understanding of immigrant human capital on the ground, the study has found structural and institutional practices inherent in the Canadian labour market that are principal reasons for many immigrants’ poor labour market outcomes. Evidence from the study strongly suggests that there is an issue of racism and sexism at play in the Canadian labour market that negatively affects outcomes for Caribbean immigrants in Toronto.     

Do They Know How Happy They Are? On the Value of Self-Rated Happiness of People With a Mental Disorder

Quality of life is often measured using questions about happiness. This method presumes that respondents are able to judge their life. Research suggest that this is typically the case, but this is not to say that everybody can. In that context one may doubt whether people with a mental disorder can judge their life adequately. Happiness can be rejected as a indicator for quality of life for people with mental disorders, because of affective and cognitive distortions. We therefore checked the validity of happiness and satisfaction measures in the context of mental disorders. Psychiatric diagnoses were determined at baseline and at 12 and 36 months follow-up in a representative sample (N = 7,076) of the Dutch population, using a full Composite International Diagnostic Interview. Respondents indicated how often they had felt happy during the past month and how satisfied they were with their lives in general. The measurements have a satisfactory concurrent, ecological and predictive validity for people with mental disorders. Though the level of happiness is lower among the people with mental disorders, conditions for happiness and contentment appear to be similar.     

Increasing following headway with prompts, goal setting, and feedback in a driving simulator

We evaluated the effects of prompting, goal setting, and feedback on following headway of young drivers in a simulated driving environment and assessed whether changes produced in following headway were associated with reductions in hard braking when drivers were and were not using cell phones. Participants were 4 university students. During baseline, drivers spent half of the time talking on cell phones while driving. At the start of the intervention, drivers were prompted to increase following headway while on the cell phones and were provided a specific target for following headway. Drivers were given feedback on increasing following headway when on cell phones at the end of each session. The intervention package was associated with an increase in following headway and a decrease in hard braking when participants were on and off the cell phones. Cell phone use did not affect any of the measures.     

The Link: An Alternative Educational Program in the Netherlands to Reengage School-Refusing Adolescents With Schooling

Facets of school life affect the development and maintenance of school refusal (SR). These facets will warrant attention during intervention for SR. This paper considers a range of school-related factors associated with SR, grouped according to five domains of school climate. It also describes school-based interventions for SR in the form of alternative educational programs (AEPs). The paper then presents the Link, an AEP for Dutch adolescents with SR. The Link offers an educational setting that addresses school-related factors associated with SR. After participation in the Link, adolescents are helped to return to a more typical educational setting. Based on a review of 30 case files, we provide an account of adolescents who have participated in the Link. Often, these adolescents displayed chronic and severe SR, met criteria for anxiety or depressive disorders, and were diagnosed with an autism spectrum disorder. The Link process is illustrated via a case vignette. Thereafter, the role of AEPs in the treatment of SR is discussed.     

Diagnostics of phonological lexical processing: pseudohomophone naming advantages,disadvantages, and base-word frequency effects

Phonological lexical access has been investigated by examining both a pseudohomophone (e.g., brane) base-word frequency effect and a pseudohomophone advantage over pronounceable nonwords (e.g., frane) in a single mixed block of naming trials. With a new set of pseudohomophones and non-words presented in a mixed block, we replicated the standard finding in the naming literature: no reliable base-word frequency effect, and apseudohomophone advantage. However, for this and two of three other sets of stimuli--those of McCann and Besner (1987), Seidenberg, Petersen, MacDonald, and Plaut (1996), and Herdman, LeFevre, and Greenham (1996), respectively--reliable effects of base-word frequency on pseudohomophone naming latency were found when pseudohomophones were presented in pure blocks prior to nonwords. Three of the four stimulus sets tested produced a pseudohomophone naming disadvantage when pseudohomophones were presented prior to nonwords. When nonwords were presented first, these effects were diminished. A strategy-based scaling account of the data is argued to provide a better explanation of the data than is the criterion-homogenization theory (Lupker, Brown, & Colombo, 1997).
