Salivary concentrations of cortisol and testosterone and prediction of performance in a professional triathlon competition

The aim of this study was to examine salivary cortisol and testosterone concentrations in professional male athletes during a short triathlon competition using non-invasive methods, and to determine whether these hormone concentrations could be accurate predictors of performance. Eight adult male athletes (age, mean ± SEM: 27.8 ± 3.2 years; body mass index: 21.66 ± 0.42) in a professional triathlon team volunteered to participate in this study. Saliva samples were taken on the competition day and 7 days after competition on a rest day. The performance of the athletes was assessed by their rank order in the competition. Salivary cortisol concentrations were greater on the competition day than on the rest day in the early morning, immediately after waking up, 30 min later, immediately before the start of the competition, and later in the evening. Testosterone concentrations were greater on the competition day in the morning and in the evening. The diurnal rhythm of both cortisol and testosterone concentrations was maintained on both days and the testosterone/cortisol ratio (T/C ratio) was similar between days. The performance of the athletes was positively correlated with salivary cortisol concentration in the early morning of the competition day, but was not correlated with testosterone concentrations at any of the time points. In conclusion, early morning salivary cortisol concentration, but not T/C ratio, could be used to predict performance in athletes during a professional triathlon competition.     

Meta-analysis of the Long-Term Treatment Effects of Psychological Interventions in Youth with PTSD Symptoms

To date, the long-term effectiveness of psychological treatments in reducing post-traumatic stress disorder symptoms in children and adolescents has not been investigated extensively. This meta-analysis quantifies the long-term effects of psychological interventions in children and adolescents with PTSD symptoms and examines the period-dependent follow-up (FU) effects based on 47 studies. The mean FU effect sizes (ESs) for PTSD symptoms ranged from medium (between treatment ESs for controlled studies) to large (within treatment ESs for uncontrolled studies; pooled analysis including all studies). These effects were comparable to the post-treatment ESs, which suggests that the treatment effects remained stable. ESs did not differ depending on the length of the FU period (</>6 months). In randomized controlled trials (RCTs), as well as trials conducted with treatment as usual or active control groups, the long-term treatment effects for the reduction of PTSD symptoms were small. These results demonstrate the long-term effectiveness of psychological interventions in the treatment of PTSD in youth. However, more studies should include a FU assessment. Further research should focus on RCTs with long-term assessments, report comorbid symptoms and investigate the influence of potential moderators. Research is also warranted to determine how to improve the long-term effects of treatments for PTSD in youth.     

Recovering from negative events by boosting implicit positive affect

Upregulation of implicit positive affect (PA) can act as a mechanism to deal with negative affect. Two studies tracked temporal changes in positive and negative affect (NA) assessed by self-report and the Implicit Positive and Negative Affect Test (IPANAT; Quirin, Kazen, & Kuhl, 2009). Study 1 observed the predicted increases in implicit PA after exposure to a threat-related film clip, which correlated positively with the speed of recognising a happy face among an angry crowd. Study 2 replicated increases in implicit PA after exposition to the same film clip, and showed that such increases were enhanced by priming self-referential stimuli. The findings are discussed against the background of personality systems interaction (PSI) theory (Kuhl, 2000, 2001), which emphasises the role of the implicit self in affect regulation.     

Culture masquerading,identity and organizational commitment

This mixed method study examines the impact of culture masquerading among 488 Filipino customer service representatives handling international accounts. Culture masquerading is practised via taking on foreign names, locations and nationalities. Applying social identity theory, it is hypothesized and supported that masquerading of nationality is negatively related to cultural identity. As predicted, there is a positive relationship between cultural identity and organization commitment. No support is found for the hypothesis that cultural identity mediates the relationship between culture masquerading. Situated identity theory and economic, social, and historical influences are used to explain these findings.     

Racial/ethnic differences in the influence of cultural values, alcohol resistance self-efficacy, and alcohol expectancies on risk for alcohol initiation

Prior research has reported racial/ethnic differences in the early initiation of alcohol use, suggesting that cultural values that are central to specific racial/ethnic groups may be influencing these differences. This 1-year longitudinal study examines associations between two types of cultural values, parental respect (honor for one's parents) and familism (connectedness with family), both measured at baseline, and subsequent alcohol initiation in a sample of 6,054 (approximately 49% male, 57% Hispanic, 22% Asian, 18% non-Hispanic White, and 4% non-Hispanic Black) middle school students in Southern California. We tested whether the associations of cultural values with alcohol initiation could be explained by baseline measures of alcohol resistance self-efficacy (RSE) and alcohol expectancies. We also explored whether these pathways differed by race/ethnicity. In the full sample, adolescents with higher parental respect were less likely to initiate alcohol use, an association that was partially explained by higher RSE and fewer positive alcohol expectancies. Familism was not significantly related to alcohol initiation. Comparing racial/ethnic groups, higher parental respect was protective against alcohol initiation for Whites and Asians, but not Blacks or Hispanics. There were no racial/ethnic differences in the association between familism and alcohol initiation. Results suggest that cultural values are important factors in the decision to use alcohol and these values appear to operate in part, by influencing alcohol positive expectancies and RSE. Interventions that focus on maintaining strong cultural values and building strong bonds between adolescents and their families may help reduce the risk of alcohol initiation.

Implicit Memory in Korsakoff’s Syndrome: A Review of Procedural Learning and Priming Studies

Korsakoff's syndrome (KS) is characterized by dense anterograde amnesia resulting from damage to the diencephalon region, typically resulting from chronic alcohol abuse and thiamine deficiency. This review assesses the integrity of the implicit memory system in KS, focusing on studies of procedural learning and priming. KS patients are impaired on several measures of procedural memory, most likely due to impairment in cognitive functions associated with alcohol-related neural damage outside of the diencephalon. The pattern of performance on tasks of implicit priming suggests reliance on a residual, non-flexible memory operating more or less in an automatic fashion. Our review concludes that whether measures of implicit memory reveal intact or impaired performance in individuals with KS depends heavily on specific task parameters and demands, including timing between stimuli, the specific nature of the stimuli used in a task, and the integrity of supportive cognitive functions necessary for performance.     

The Five Whys Method: A Tool for Developing Problem Definitions in Collaboration with Children

Participatory action research with young people (yPAR) involves youth and adults in a collaborative process of research, reflection, analysis and action. An important part of the research cycle is the identification of a problem definition. Yet, there is relatively little research addressing the process of how young people develop a problem definition on which to focus their analysis and intervention and what methods might exist to facilitate this process. This article draws upon a yPAR project with fifth‐grade working‐class young people, primarily young people of colour, to demonstrate how the Five Whys method for reflecting on lived experiences facilitated the development of problem definitions in line with second‐order change. The Five Whys method, when used within a participatory framework, offers both a context and a structure for young people to critically examine social problems they identify and to seek out root causes. The article highlights changes in the participant's formulation of problems in the context of using the Five Whys method, from a primarily individual level of analysis to a more structural level of analysis. It also outlines the subsequent changes in proposed actions to address the identified problems. Copyright © 2011 John Wiley & Sons, Ltd.

Spirituality of Chronic Orofacial Pain Patients: Case–Control Study

The objective of this study was to investigate spirituality and blood parameters associated with stress in patients with facial musculoskeletal pain. Twenty-four women with chronic facial musculoskeletal pain (CFMP) and 24 healthy women were evaluated with a protocol for orofacial characteristics, research diagnostic criteria for temporomandibular disorders and the Spiritual Perspective Scale. Blood samples were collected to analyze blood count, cortisol, ACTH, C3, C4, thyroid hormones, total immunoglobulin, C-reactive protein and rheumatoid factor. The study group was more spiritualized than control group. Individuals with a high score of spirituality had less myofascial pain, less bruxism and fewer complaints. They also had lower levels of ACTH and IgE. Spirituality was higher in the study group and can be considered an important tool for coping with CFMP.
