A longitudinal study of the psychosocial impact of stroke on primary support persons

We investigated longitudinally the effects of a stroke on the social support systems and well-being of the patient's primary support person, both acutely and as the condition stabilized. Individuals who had suffered a first stroke and a primary support person participated in two waves of data collection, carried out in 6-month intervals beginning 7 weeks after the stroke. Our data show that the prevalence of depressive symptoms is from 2 1/2 to 3 1/2 times higher than rates found among representative samples of middle-aged and elderly populations. Mean level of depression did not change over time, although level of optimism declined significantly. Multiple regression analyses showed that levels of depression and perceived burden in support persons are highly related to aspects of the stroke such as its severity, and that demographic variables such as age and income play a relatively minor role in attenuating these relations in the acute adjustment phase. However, from 7 to 9 months after the stroke, well-established demographic variables such as health, income, and age were significant predictors of depression. Individuals who were older and who had good health and higher incomes were least depressed.     

Beliefs and inferences: A test of a rational-emotive hypothesis 1. Performing in an academic seminar

Subjects were asked to imagine that they were going to present an academic seminar. They were further asked to imagine (a) that they adhered to a rational belief or an irrational belief; (b) that they had made or had not made an effort in preparing for the seminar and (c) that their performance counted or did not count towards their final examination grade. Whilst in role, subjects were asked to make inferences about various aspects of their performance and the responses of others. While the results supported the hypothesis that imagining that one is holding an irrational belief leads to more negative inferences than holding a rational belief, it was also found that not making an effort in preparing for the siminar led subjects to make more negative inferences than making an effort. In addition, there were several two-way and three-way significant interactions between the independent variables. The results supported Ellis's (1985) recent formulation concerning the complex relationship between events and inferences (A), beliefs (B) and emotional and behavioral consequences of beliefs (C).Windy Dryden PhD is Senior Lecturer in the Department of Psychology, Goldsmiths' College, University of London, England.

Counting On Blood Donors: Increasing the Impact of Reminder Calls

Two experiments were conducted to see if blood drive attendance could be increased by altering the content of reminder calls. In Experiment 1 college students received either a standard reminder (the place, time, and necessity of eating beforehand) or a commitment-enhancing reminder in which they agreed to be "counted on". Those in the latter condition were significantly more likely (p <.007) to attend a blood drive. Experiment 2 demonstrated that an alternate wording for the commitment-enhancing message was possible; that a verbal response was necessary to ensure the commitment; and that a message enhancing altruism was not as effective. The studies suggest that asking for an additional commitment during a reminder call can appreciably increase blood drive participation rates.     

The roles of self-regulation and partner regulation on romantic relationship quality

Research into self-regulation and partner regulation strategies has largely involved parallel lines of research, thus, it is difficult to determine the relative contribution of both forms of regulation when it comes to relationship outcomes. Therefore, the question remains as to which form of regulation is more strongly associated with relationship quality; is it more important to focus on adaptive self-regulation or adaptive strategies to regulate one's partner? The current research addresses this important gap by comparing the relative associations of adaptive self-regulation and adaptive partner regulation strategies on romantic relationship quality. A community sample of mixed gender couples (N = 114) who were predominantly satisfied with their current relationships – but nonetheless still experienced relationship conflict – were administered self-report assessments of various self-regulation and partner regulation strategies as well as a measure of relationship quality. Couples also participated in a videotaped discussion of an unresolved relationship issue that was scored by trained coders for verbal and nonverbal indicators of self-regulation and partner regulation strategies. Actor–partner interdependence modeling revealed that for both men and women, adaptive self-regulation strategies were positively associated with their own evaluations of relationship quality as well as their partner's relationship quality. In contrast, engaging in adaptive partner regulation strategies was not significantly associated with men's or women's own, or their partner's relationship quality. Findings highlight the importance of focusing on self-regulation in relationships, as it is these strategies, over partner regulation strategies, that have more positive implications for the relationship quality experienced by typically satisfied couples.

Susceptibility to prosocial and antisocial influence in adolescence following mindfulness training

Mindfulness training programmes have shown to encourage prosocial behaviours and reduce antisocial tendencies in adolescents. However, less is known about whether training affects susceptibility to prosocial and antisocial influence. The current study investigated the effect of mindfulness training (compared with an active control) on self-reported prosocial and antisocial tendencies and susceptibility to prosocial and antisocial influence. 465 adolescents aged 11–16 years were randomly allocated to one of two training programmes. Pre- and post-training, participants completed a social influence task. Self-reported likelihood of engaging in prosocial and antisocial behaviours did not change post-training, and regardless of training group, participants showed a higher propensity for prosocial influence than for antisocial influence. Finally, participants were less influenced by antisocial ratings following both training programmes.     

Memory lapses during a pandemic: Differential associations between COVID-stress and daily memory lapses?

The policies related to COVID-19 pandemic such as stay at home orders and social distancing increased daily stress and associated impairments in mental health. This study examines the association between COVID-related stress and cognitive functioning by examining two different types of daily memory lapses, those related to prospective memory (i.e., memory for future plans) and retrospective memory (i.e., memory for past information) as well as the perceived emotional and functional consequences of daily memory problems. As part of a larger study, 58 adults (18 men; 22 ± 3 years) completed a web-based version of the daily inventory of stressful events including stress related to COVID-19 and positive/negative affect for eight consecutive days between 8 September 2020 and 11 November 2020. Findings showed that prospective lapses were positively correlated with COVID-19 stressors (r = 0.41, p = 0.002). At the within-person level, daily COVID-19 stressors were significantly associated with the number of prospective lapses (b = 0.088, SE = 0.040). COVID-19-related stressors were not significantly related to retrospective lapses (all ps > 0.05). Our findings suggested that more daily COVID-19 stressors were related to greater numbers of prospective lapses in daily life even among healthy younger adults. Thus, future research should address long term relations of COVID-19 stress and cognitive functioning in addition to the specific cognitive impairments related to COVID-19 infection.     

A general rotation criterion and its use in orthogonal rotation

Measures of test parsimony and factor parsimony are defined. Minimizing their weighted sum produces a general rotation criterion for either oblique or orthogonal rotation. The quartimax, varimax and equamax criteria are special cases of the expression. Two new criteria are developed. One of these, the parsimax criterion, apparently gives excellent results. It is argued that one of the most important factors bearing on the choice of a rotation criterion for a particular problem is the amount of information available on the number of factors that should be rotated.
