Optimism,well-being,depressive symptoms,and perceived physical health: a study among Stroke survivors

The investigation of the relation of positive personality characteristics to mental and physical health among Stroke survivors has been a neglected area of research. The purpose of this study was to examine the relationship between optimism, well-being, depressive symptoms, and perceived physical health among Stroke survivors. It was hypothesized that Stroke survivors’ optimism would explain variance in their physical health above and beyond the variance explained by demographic variables, diagnostic variables, and mental health. One hundred seventy-six Stroke survivors (97 females, 79 males) completed the Revised Life Orientation Test, the Center for Epidemiological Studies Depression Scale, two items on perceived physical health from the 36-item Short Form of the Medical Outcomes study, and the Identity scale of the Illness Perception Questionnaire. Pearson correlations, hierarchical regression analyses, and the PROCESS approach to determining mediators were used to assess hypothesized relations between variables. Stroke survivors’ level of optimism explained additional variance in overall health in regression models controlling for demographic and diagnostic variables, and mental health. Analyses revealed that optimism played a partial mediator role between mental health (well-being, depressive symptoms and total score on CES-D) variables and overall health.     

How honest are the signals? A protocol for validating wearable sensors

There is growing interest among organizational researchers in tapping into alternative sources of data beyond self-reports to provide a new avenue for measuring behavioral constructs. Use of alternative data sources such as wearable sensors is necessary for developing theory and enhancing organizational practice. Although wearable sensors are now commercially available, the veracity of the data they capture is largely unknown and mostly based on manufacturers’ claims. The goal of this research is to test the validity and reliability of data captured by one such wearable badge (by Humanyze) in the context of structured meetings where all individuals wear a badge for the duration of the encounter. We developed a series of studies, each targeting a specific sensor of this badge that is relevant for structured meetings, and we make specific recommendations for badge data usage based on our validation results. We have incorporated the insights from our studies on a website that researchers can use to conduct validation tests for their badges, upload their data, and assess the validity of the data. We discuss this website in the corresponding studies.     

Callous-Unemotional Traits,Relational and Social Aggression,and Interpersonal Maturity in a Sample of Behaviorally Disordered Adolescents

The authors examined the degree to which callous-unemotional traits and narcissism predict relational aggression, social aggression, and prosocial skills in a sample of 79 adolescent offenders (13–18 years old; 26% girls; 74% boys) attending a school for youth with behavior disorders in the Mid-Atlantic United States. Narcissism made a significant contribution to the prediction of both relational aggression and social aggression, accounting for most of the unique variance in the prediction of these indirect forms of aggression. Conversely, callous-unemotional traits—but not narcissism—made a significant contribution to the prediction of lower prosocial skills. Furthermore, in contrast to the large number of studies indicating gender differences in the expression of aggression, no significant gender differences in the present study were found.     

Development and evaluation of a scale assessing therapist fidelity to guidelines for delivering therapist-assisted Internet-delivered cognitive behaviour therapy

Internet-delivered cognitive behaviour therapy (ICBT) is often accompanied by therapist emails, but there is limited research on the quality of this therapist-assistance. In this study, an ICBT Therapist Rating Scale (ICBT-TRS) was developed and evaluated to assess whether therapist emails showed fidelity to specific therapist behaviours. Using data from a previous ICBT trial for depression and anxiety, the ICBT-TRS was used to rate 706 emails sent by 39 therapists to 91 randomly selected patients. Emails were rated for adherence (absent/present) and quality (inadequate/competent) on the following behaviours: Builds Rapport, Seeks Feedback, Provides Symptom Feedback, Provides Psychoeducation, Facilitates Understanding, Praises Effort, Encourages Practice, Clarifies Administrative Procedures, and Communicates Effectively. Inter-rater reliability was high. Most behaviours were identified as present in 72–100% of emails, with the exception of Provides Symptom Feedback and Facilitating Understanding which were only present in 54 and 61% of emails. The majority of emails were rated as high quality (88–98% of messages). While not related to symptom improvement, ICBT-TRS ratings were higher when patients were more engaged in ICBT (e.g. log-ins) and among therapists who specialized in ICBT or had a background in Psychology. The ICBT-TRS has potential to facilitate ICBT research and clinical training.     

Coping and Positive Affect in Adolescents of Mothers With and Without a History of Depression

The adolescent children of depressed mothers are at increased risk for depression, but little is known about protective factors for these children. Maintenance of positive affect in a stressful context may be an important marker of resilience. Mothers with (n = 34) and without (n = 38) a history of depression and their adolescent children completed questionnaires regarding adolescents’ coping and depressive symptoms and engaged in a 15 min videotaped interaction about family stress. Adolescents’ observed behaviors were coded using the Iowa Family Interaction Rating Scales. No significant differences emerged in observed behavior between adolescents of mothers with and without a history of depression. Higher levels of primary and secondary control coping and lower levels of disengagement coping were related to higher levels of observed positive mood and fewer depressive symptoms in adolescents. Observed positive mood was related to fewer depressive symptoms in adolescents, even after accounting for maternal history of depression and current maternal depressive symptoms. Results suggest the importance of considering positive affect in the context of family stress as a marker of resilience in adolescents at risk for depression. The current study provides evidence for coping as a protective factor, related to higher levels of positive affect and fewer depressive symptoms, in adolescents exposed to maternal depressive symptoms.     

Virtual muscularity: a content analysis of male video game characters

The 150 top-selling video games were content analyzed to study representations of male bodies. Human males in the games were captured via screenshot and body parts measured. These measurements were then compared to anthropometric data drawn from a representative sample of 1120 North American men. Characters at high levels of photorealism were larger than the average American male, but these characters did not mirror the V-shaped ideal found in mainstream media. Characters at low levels of photorealism were also larger than the average American male, but these characters were so much larger that they appeared cartoonish. Idealized male characters were more likely to be found in games for children than in games for adults. Implications for cultivation theory are discussed.     

Resource allocation during spoken discourse processing: Effects of age and passage difficulty as revealed by self-paced listening

The allocation of processing resources during spoken discourse comprehension was studied in a manner analogous to self-paced reading using the auditory moving window technique (Ferreira, Henderson, Anes, Weeks, & McFarlane, 1996). Young and older participants listened to spoken passages in a self-paced segment-by-segment fashion. In Experiment 1, we examined the influence of speech rate and passage complexity on discourse encoding and recall performance. In Experiment 2, we examined the influence of speech rate and presentation mode (self-paced vs. full-passage presentation) on recall performance. Results suggest that diminished memory performance in the older adult group relative to the young adult group is attributable to age-related differences in how resources were allocated during the initial encoding of the spoken discourse.     

Global and local processing in adult humans (Homo sapiens), 5-year-old children (Homo sapiens), and adult cotton-top tamarins (Saguinus oedipus)

This study compared adults (Homo sapiens), young children (Homo sapiens), and adult tamarins (Saguinus oedipus) while they discriminated global and local properties of stimuli. Subjects were trained to discriminate a circle made of circle elements from a square made of square elements and were tested with circles made of squares and squares made of circles. Adult humans showed a global bias in testing that was unaffected by the density of the elements in the stimuli. Children showed a global bias with dense displays but discriminated by both local and global properties with sparse displays. Adult tamarins' biases matched those of the children. The striking similarity between the perceptual processing of adult monkeys and humans diagnosed with autism and the difference between this and normatively developing human perception is discussed.     

The Impact of First-Grade “Friendship Group” Experiences on Child Social Outcomes in the Fast Track Program

Many interventions for childrens behavior problems successfully utilize a group format for social skills training, providing opportunities for practice and performance feedback from peers. Recent studies however, suggest that grouping aggressive children together may reduce intervention effectiveness or even increase risk. The present study examined the relative impact of childrens own behavior and their experiences with peers in the first-grade friendship groups of Fast Track, a multi-component preventive intervention program. Two-hundred sixty-six children (56% minority, 29% female) participated in 55 friendship groups. Childrens own positive and negative behavior in friendship groups was related to relative improvements in social cognitive skills, prosocial behavior, and aggression, assessed through child interviews, teacher ratings, and peer sociometric nominations. Results from hierarchical linear models also revealed that the amount of peer escalation children received for their disruptive behavior during sessions impeded some intervention gains, whereas mere exposure to other childrens positive or negative behavior was rarely related to outcomes.Members of the Conduct Problems Prevention Research Group are, in alphabetical order, Karen L.

Individual differences in emotional memory: adult attachment and long-term memory for child sexual abuse

In the present study, attachment-related differences in long-term memory for a highly emotional life event, child sexual abuse (CSA), were investigated. Participants were 102 documented CSA victims whose cases were referred for prosecution approximately 14 years earlier. Consistent with the proposal that avoidant individuals defensively regulate the processing of potentially distressing information (Bowlby, 1980), attachment avoidance was negatively associated with memory for particularly severe CSA incidents. This finding was not mediated by the extent to which participants reported talking about the abuse after it occurred, although post abuse discussion did enhance long-term memory. In addition, accuracy was positively associated with maternal support following the abuse and extent of CSA-related legal involvement. Attachment anxiety was unrelated to memory accuracy, regardless of abuse severity. Implications of the findings for theories of avoidant defensive strategies and emotional memory are discussed.
