Adherence to antiretroviral medications in HIV: differences in data collected via self-report and electronic monitoring.

Controversy remains regarding the reliability of methods used to determine adherence to antiretroviral medication in HIV. In this study the authors compared adherence rates of 119 HIV-positive participants during a 6-month study, as estimated via electronic monitoring (EM) and self-report (SR). Adherence for both short (4-day) and long (4-week, or intervisit) periods was examined, as well as factors that underlie discrepancies between EM and SR. Results showed that intervisit EM estimates were consistently lower than those of SR. SR estimates based on shorter periods (4 days) were closer to those of EM. Higher discrepancies between EM and SR estimates were associated with lower cognitive functioning and externalized locus of control. These findings lend support for using both EM and SR methods; however, study design (e.g., length) and other factors (e.g., cognitive status, cost) should be considered.     

The effects of Brazelton intervention: A review

This article reviews research that has used the Brazelton Neonatal Behavioral Assessment Scale (NBAS; Brazelton, 1984) as an intervention. It discusses separately the various effects NBAS intervention has been found to have in areas such as parent-infant interaction, infant development, temperament, and parental attitudes and satisfaction. Inconsistent findings are noted in each of these areas. This article then addresses issues that may play a role in the effectiveness of NBAS intervention, including the risk status of the population, the intensity of the intervention, and the receptivity of the parent. It concludes by suggesting that realistic goals be set concerning the expectations for early, short-term intervention such as the NBAS.     

Evidence of Absence: Abstract Metrical Structure in Speech Planning

Rhythmic structure in speech is characterized by sequences of stressed and unstressed syllables. A large body of literature suggests that speakers of English attempt to achieve rhythmic harmony by evenly distributing stressed syllables throughout prosodic phrases. The question remains as to how speakers plan metrical structure during speech production and whether it is planned independently of phonemes. To examine this, we designed a tongue twister task consisting of disyllabic word pairs with overlapping phonological segments and either matching or non-matching metrical structure. Results showed that speakers had more difficulty producing metrically regular word pairs, compared to irregular pairs; that is, word pairs with irregular meter had faster productions and fewer speech errors in this production task. This finding of metrical regularity inhibiting production is inconsistent with an abstract metrical structure that is planned independently of phonemes at the point of phonological encoding.     

Predicting Burnout Among HIV/AIDS and Oncology Health Care Workers

Abstract

This study examined the relationship between repressive coping, controllability, self-esteem and comparative optimism for health-related events. Repressors (low trait anxiety-high defensiveness) compared with both (a) specific control groups on anxiety and defensiveness (e.g., low-anxious, high-anxious and defensive high anxious) and (b) total nonrepressors were significantly more comparatively optimistic for health-related events. Repressors remained significantly more comparatively optimistic than total nonrepressors when self-esteem was partialled out.

For individual events, repressors differed in comparative optimism for events which were rated as high controllability. It is concluded that repressors are exhibiting comparative optimism over and above nonrepressor groups for events which are rated as controllable. These results suggest that comparative optimism findings may be exaggerated by not controlling for the disproportionate influence of repressors in skewing sample means. Suggestions for future studies are discussed.     

Illness perceptions and self efficacy beliefs in adolescents and young adults with insulin dependent diabetes mellitus

Abstract

The study examined the role of illness perceptions and self-efficacy in diabetic regimen adherence and metabolic control among young patients with Insulin Dependent Diabetes Mellitus (IDDM). Sixty-four outpatients with Insulin Dependent Diabetes completed measures of illness perceptions, generalised and diabetes specific self-efficacy and a self-report measure of adherence. Metabolic control (HbAlc) was also assessed. Control, identity and consequences components of illness perceptions were significantly correlated with self-efficacy expectancies. Control beliefs were consistently associated with self-reported adherence across all treatment aspects and accounted for 39% of the predicted variance in total adherence. The associations of the other psychological predictors examined, varied depending on the regimen area. Multiple regression analysis showed that 30.8% of the variance in HbAlc assays was explained by patients' diabetes specific self-efficacy, consequences and identity. Our findings suggest that patients' beliefs are useful predictors of physiological and behavioural outcomes in diabetes self-management and should thus be the focus of routine clinical assessments and future interventions.     

Identifying repressors: A methodological issue for health psychology

Abstract

The majority of studies in health psychology use self-report measures. However, there is a growing body of evidence indicating that this methodology may be problematic for a significant minority of the population: individuals who possess a repressive coping style (repressors). Repressors, who fail to report negative affect, answer many self-report measures in a positive fashion. Research has identified an association between repressors, who are identified by low trait anxiety scores and high defensiveness scores, and adverse health outcomes. Therefore, repressors are an important group for health psychologists to investigate. Health psychology research should use more than one method of data collection in an attempt to unravel this difficult methodological problem.
