Feedback and performance expectancies in an academic setting

College students in two psychology courses estimated their confidence in passing and their anticipated score for three examinations. On the first examination the results from both courses supported the prediction that women, compared to men, would be less confident of passing, would predict lower scores, and would underestimate their obtained scores. These sex differences disappeared, as predicted, on the second and third examination for the course, in which the situation remained relatively constant over the term. However, contrary to predictions, the sex differences were maintained over all three examinations for the second course, which involved different instructors for each exam. Thus, the effects of feedback on performance expectancies seem to be vulnerable to situational changes.     

Commonsense beliefs about depression and antidepressive behaviour: A study of social consensus

The present study examines consensus in endorsed beliefs about depression and antidepressive behaviour in a group of 100 psychologists. Ss were given 20 pairs of items and asked to indicate which member of each pair they felt was ‘nearer the truth’. The numbers (and percentages) of Ss choosing each item was examined for each pair. Consensus was found to span the range from 100% agreement to near-complete disagreement and to be distributed roughly normally within the sample of items. People tended to agree about propositions that could be verified by an individual's own firsthand experience and observation and to disagree about more abstract matters that the ‘experts’ are still debating. The congruence of these findings with previous results in the present series of studies is discussed and suggestions for further exploration in the realm of ‘what everybody knows’ about depression and how to deal with it are given.     

The role of anxiety sensitivity in the relationship between posttraumatic stress symptoms and negative outcomes in trauma-exposed adults

Background: The development of posttraumatic stress symptoms (PTSs) following a trauma is related to impairment, diminished quality of life, and physical health issues. Yet it is not clear why some trauma-exposed individuals experience negative outcomes while others do not. The purpose of this study was to determine the role of several influential factors related to PTS severity and negative outcomes. Methods: One hundred and twenty-two trauma-exposed adults were administered the following self-report measures: the Posttraumatic Stress Disorder Checklist-Civilian, the Trauma History Questionnaire-Short, the Anxiety Sensitivity Index-3, Depression and Anxiety Stress Scale 21, Sheehan Disability Scale, World Health Organization Quality of Life-BREF, and an abbreviated Patient Health Questionnaire. Primary Results: PTS severity was positively correlated with depressive symptom severity (r = 0.54, p < 0.001), chronicity of the most distressing trauma (r = 0.21, p = 0.017), and number of traumas (r = 0.22, p = 0.012). Main effects were found for PTS severity (β = ?0.38, p < 0.01) and anxiety sensitivity (AS; β = ?0.39, p < 0.01) on quality of life. No interaction was found between PTS severity and AS with any negative outcome. PTS severity mediated the relationship between AS and physical health issues (0.05; 95% CI: 0.02–0.08). Conclusion: This study helps clarify the role of various factors in the relationship between trauma and negative outcomes. Clinical and research implications are discussed.     

Time estimation: does the reference memory mediate the effect of knowledge of results?

This study presents evidence for the role of knowledge of results (KR) in the estimation of medium time intervals (4-12 s durations). Experiment 1 tested the hypothesis that KR operates at the same stage of temporal processing as attention. The absence of an interaction of attention and KR is taken as evidence against this hypothesis. Experiments 2 and 3 further studied the effects of KR in a reproduction and a production task, respectively. The effects of KR were small in the reproduction and substantial in the production task. The results are interpreted in terms of a clock-based timing model and the findings taken together converge on the interpretation that KR affects the reference memory (RM), rather than the other components of the model.     

Examining Factors Associated with Primary Care and Continuity of Care Among Adults with Severe Mental Illness

A number of studies have consistently reported that there is a greater prevalence of mental illness among the most socioeconomically disadvantaged. At the same time, there is evidence that services are not optimally accessed by the most socioeconomically disadvantaged; the most in need of care are also the most likely to have unmet healthcare needs. Of people with mental illnesses, those with severe mental illnesses (SMI) are the most at risk of poverty and the least likely to have optimal care. In the past, specialized community mental health services have been identified as the primary provider for people with SMI. However, there is growing interest in using the primary care setting as the main source of mental health care where both medical treatment and psychotherapy can be accessed. In this paper, we examine factors related to primary care use (and in turn, pharmacologic and psychotherapies) for people who are socioeconomically disadvantaged and who have a SMI.
