Illness Perception and Well-Being Among Persons with Multiple Sclerosis and Their Caregivers

This study jointly examined illness beliefs held by persons with multiple sclerosis (PwMS) and caregivers in relation to well-being. A group of 68 PwMS and their caregivers completed the Revised Illness Perception Questionnaire, Psychological Well-being Scales, Satisfaction with Life Scale and Positive Affect and Negative Affect Schedule. Findings revealed that PwMS’ well-being was primarily predicted by their own illness beliefs, and that also caregivers’ well-being was primarily predicted by their own beliefs. Across the two groups, well-being was positively associated with their belief that they understood the disease, and inversely associated with their representations of negative emotions. In addition, among PwMS, well-being was inversely associated with the number of symptoms they specifically attributed to their illness, while among caregivers, well-being was positively associated with beliefs that treatment could control the disease. Based on the study findings, psychoeducational and cognitive-behavioral strategies are suggested to promote well-being among PwMS and caregivers.     

Predicting foreign-accent adaptation in older adults

We investigated comprehension of and adaptation to speech in an unfamiliar accent in older adults. Participants performed a speeded sentence verification task for accented sentences: one group upon auditory-only presentation, and the other group upon audiovisual presentation. Our questions were whether audiovisual presentation would facilitate adaptation to the novel accent, and which cognitive and linguistic measures would predict adaptation. Participants were therefore tested on a range of background tests: hearing acuity, auditory verbal short-term memory, working memory, attention-switching control, selective attention, and vocabulary knowledge. Both auditory-only and audiovisual groups showed improved accuracy and decreasing response times over the course of the experiment, effectively showing accent adaptation. Even though the total amount of improvement was similar for the auditory-only and audiovisual groups, initial rate of adaptation was faster in the audiovisual group. Hearing sensitivity and short-term and working memory measures were associated with efficient processing of the novel accent. Analysis of the relationship between accent comprehension and the background tests revealed furthermore that selective attention and vocabulary size predicted the amount of adaptation over the course of the experiment. These results suggest that vocabulary knowledge and attentional abilities facilitate the attention-shifting strategies proposed to be required for perceptual learning.     

Internet Communication and Its Relation to Well-Being: Identifying Some Underlying Mechanisms

Abstract

The aim of this study was to improve our insight into the relation between Internet communication and well-being. Drawing on a survey of 816 adolescents, we initially found that Internet communication was negatively related to well-being. However, when adolescents’ (a) closeness to friends and (b) tendency to talk with strangers online were included in our structural equation model, an opposite pattern of results emerged. First, the direct negative relation between Internet communication and well-being disappeared. Second, via the mediator closeness to friends, Internet communication showed a positive influence on well-being. Third, not Internet communication per se, but Internet communication with strangers accounted for a negative effect on well-being. Fourth, the effects of both Internet communication and Internet communication with strangers on well-being were most adverse for lonely adolescents.     

Adolescents' Exposure to Sexually Explicit Internet Material and Sexual Preoccupancy: A Three-Wave Panel Study

The main aim of this study was to investigate whether adolescents' use of sexually explicit Internet material (SEIM) increased their sexual preoccupancy (i.e., a strong cognitive engagement in sexual issues). Further, we wanted to know (a) whether subjective sexual arousal mediated a potential influence of exposure to SEIM on sexual preoccupancy and (b) whether this process differed between male and female adolescents. Over the course of one year, we surveyed 962 Dutch adolescents aged 13–20 years three times. Structural equation modeling showed that exposure to SEIM stimulated sexual preoccupancy. This influence was fully mediated by subjective sexual arousal from SEIM. The effect of exposure to SEIM on subjective sexual arousal did not differ between male and female adolescents. The findings suggest that a sexualized media environment may affect adolescents' sexual development beyond traditionally studied variables, such as sexual attitudes and sexual behavior.     

Factor structure of the McCarthy scales for school-age children with low GCIs

This study aimed to cross-validate the factor analysis of the McCarthy Scales and to determine the construct validity of these scales for children who score one standard deviation below the normative mean on general cognitive ability. The sample was comprised of 77 children aged 6 to $\text{8}\text{1}\text{2}$ with a mean General Cognitive Index (GCI) of 61.6. Principal factor analysis produced four meaningful factors which corresponded closely to four of the scales on McCarthy's battery. The present findings discourage the interpretation of the Quantitative Scale for school-age children with GCIs below 84. Other implications of the results for the interpretation of McCarthy profiles for low-scoring school-aged children are discussed.
