Perceived mattering in stepfamilies: A social relations model analysis

The current study examined the respective role of stepfamily members' individual characteristics and their dyadic relationships in stepfamily members' perceptions of mattering to one another. Parents, stepparents, and adolescents from 86 stepfamilies participated. Applying social relations model analyses, several trends emerged regarding the relative importance of individual and dyadic factors. Parents' and adolescents' reports of mattering to one another were mainly driven by individual factors, whereas relational factors were important to understand the reports of mattering in which the stepparent was one of the dyad members. These findings contribute to stepfamily research by highlighting that stepfamily members' sense of belonging is at least partly a function of the interpersonal adaptation between the stepparent and other family members.     

Quadriceps EMG in open and closed kinetic chain tasks in women with patellofemoral pain

The authors investigated whether the discrepancy noted in the literature regarding delayed and decreased activity in vastus medialis obliquus (VMO) in people with patellofemoral pain (PFP) depends on the nature of the open kinetic chain (OKC) and the closed kinetic chain (CKC) in the experimental task. They hypothesized that activity in VMO would be more delayed and decreased in CKC tasks than in OKC tasks. Women with PFP (n = 17) and healthy controls (n = 17) performed isometric quadriceps contractions in CKC and OKC tasks. The authors manipulated only the application of resistance. Electromyographs (EMGs) showed that participants with PFP reacted later and activated the quadriceps more in the CKC task but had intramuscular quadriceps coordination similar to that of controls. The nature of the OKC task or the CKC task does not seem to explain contradictory findings regarding VMO activation.     

The perceived credibility of older adults as witnesses and its relation to ageism

In experiment 1, 267 undergraduates read a case summary and witness statement. Sex and age of the witness (49, 69, 79 or 89 years) were varied. Participants rated the witness's perceived convincingness, confidence, quality of observation, accuracy, honesty, competence, memory, suggestibility, and cognitive functioning. As well as an age effect for honesty, age by sex interactions were observed for several characteristics, particularly for comparisons of the 79-year-olds versus the 49-year-olds, and 89-year-olds versus the 49-year-olds. In experiment 2, 94 undergraduates read the same testimony given by a 79-year-old male or female witness, and completed the Fraboni Scale of Ageism and the Aging Semantic Differential. Participants who evidenced stronger aging stereotypes on these measures rated the witness less favorably than did participants who were less prejudiced. This experiment is the first to show a link between perceived credibility of older adults and ageist attitudes. Practical applications regarding how older witnesses are viewed by jurors, and the criminal justice system more generally, are discussed.     

Are the spatial features of bodily threat limited to the exact location where pain is expected?

Previous research has revealed that anticipating pain at a particular location of the body prioritizes somatosensory input presented there. The present study tested whether the spatial features of bodily threat are limited to the exact location of nociception. Participants judged which one of two tactile stimuli, presented to either hand, had been presented first, while occasionally experiencing a painful stimulus. The distance between the pain and tactile locations was manipulated. In Experiment 1, participants expected pain either proximal to one of the tactile stimuli (on the hand; near condition) or more distant on the same body part (arm; far condition). In Experiment 2, the painful stimulus was expected either proximal to one of the tactile stimuli (hand; near) or on a different body-part at the same body side (leg; far). The results revealed that in the near condition of both experiments, participants became aware of tactile stimuli presented to the “threatened” hand more quickly as compared to the “neutral” hand. Of particular interest, the data in the far conditions showed a similar prioritization effect when pain was expected at a different location of the same body part as well as when pain was expected at a different body part at the same body side. In this study, the encoding of spatial features of bodily threat was not limited to the exact location where pain was anticipated but rather generalized to the entire body part and even to different body parts at the same side of the body.     

Adult Service-Users’ Experiences of Trauma-Focused Cognitive Behavioural Therapy

This study aimed to gain an understanding of the aspects of trauma-focused cognitive behavioural therapy (Trauma-Focused-CBT) for post-traumatic stress disorder (PTSD) that service-users find important in contributing to their improvement. Nine people (5 females and 4 males, mean age 53 years old who had received on average 12 sessions of Trauma-Focused-CBT) who reported a significant reduction in their symptoms following treatment of PTSD took part in semi-structured interviews. Interpretative phenomenological analysis identified five themes: Living with Symptoms before Therapy; Feeling Ready for Therapy; Being Involved; Bringing About Therapeutic Change; and Life After Therapy. This study contributes towards a clearer understanding of the aspects of the Trauma-Focused-CBT process that service-users found important in aiding their improvement. In particular, it highlights the central role that participants attributed to their own involvement in the therapeutic process and how much they valued this. Limitations and future directions are discussed.
