Should I believe this? Reality monitoring of accounts of self-experienced and invented recent and distant autobiographical events

To examine personal and interpersonal reality monitoring, 240 participants wrote accounts of invented or self-experienced autobiographical events. Half the participants wrote about a distant event that happened before the age of 15 and half wrote about a recent event that happened after the age of 15. Using a yoked design, participants rated the qualitative details of their own accounts and the details of other participants’ accounts. Consistent with previous research, we found that self-experienced accounts contained more qualitative details than invented accounts, and that accounts of recent events contained more qualitative details than accounts of distant events. Participants rated their own accounts as more qualitatively detailed than other participants’ accounts, which suggests that they did not base their self-ratings solely on the written details. We discuss the practical and theoretical importance of our findings. Copyright # 2006 John Wiley & Sons, Ltd.

Body image and self-esteem across age and gender : a short-term longitudinal study

This study examined the relationship between body image and self-esteem across time and age for men and women. Participants were 150 men and 239 women aged between 20 and 86 years (M=59.73), recruited from the general population in Australia. They completed a questionnaire assessing self-esteem, body dissatisfaction, body importance, and a range of other domains of life satisfaction at baseline and 2 years later. Cross-sectionally, we found that higher self-esteem was associated with lower body dissatisfaction, but there was no consistent relationship between these variables across time for age and
gender. Women were more dissatisfied with their bodies than men; yet, men placed greater importance on their appearance than women, and also reported high levels of body dissatisfaction.

Relationship between inflammatory cytokines and self-report measures of training overload

It has been purported that inflammatory cytokines may be responsible for the aetiology of overtraining. The aim of the present study was to investigate the relationship between self-reported measures of overtraining and inflammatory cytokines. Eight elite male rowers were monitored in their natural training environment for 8 weeks prior to the 2007 Rowing World Championships. During this period of intense endurance training, self-report measures of overtraining and inflammatory cytokines (Interleukin (IL)-1β, IL-6, IL-8, IL-10, IL-12p70, and Tumor Necrosis Factor (TNF)-) were assessed fortnightly. Consistent with previous findings, proinflammatory cytokines IL-1β and TNF- were significantly associated (p ≤ 0.05) with measures of depressed mood, sleep disturbances, and stress. Similarly, IL-6 was significantly associated (p ≤ 0.01) with measures of depressed mood, sleep disturbances, and fatigue. These results are consistent with previous hypotheses describing how overtraining may be caused by excessive cytokine release, and lend further support for a cytokine hypothesis of overtraining.

Body image and self-concept in adolescent girls [R]

Anorexia Nervosa has been recently recognized as one of the most common chronic illnesses that affects the female adolescent population today. Although there has been an abundance of research into eating disorders in a variety of fields, significant limitations within the research still exist. Since very early descriptions of the disorder, self-concept and body image have been identified as core components of the anorexia nervosa. However, research has been somewhat limited in that there have not been any consistent theoretical underpinnings for self-concept and body image within the eating disorders field. Furthermore, researchers have tended to adopt traditional inferential statistics and multivariate methods to assess the role of self-concept and body image. As a result there has been very little consistency in research results. The current paper summarizes the significant findings from a doctoral thesis that attempted to address current limitations in self-concept and body image literature within the field of eating disorders.

Educational and mental health implications of the multidimensional model of the self-concept for adolescent girls : comparison of clinical and non-clinical samples

The importance of a positive self-concept as an educational outcome and a facilitator of other desirable outcomes are well established within the education research field. Although the multidimensional and hierarchical model of the self-concept is widely accepted within the educational psychology, this perspective is not widely used within the mental health research. Hence, the purpose of the present investigation is to compare the psychometric properties of the short version of the Self-Description Questionnaire (SDQII-S) based on responses by a large sample of female adolescent high school students (N= 829) and a clinical sample of adolescent girls who have been diagnosed with anorexia nervosa (N= 75). The well-established psychometric properties of the longer version of the SDQII generalise well to both samples of adolescent girls, and analyses provided good support for the invariance of the factor structure across the two samples. Furthermore, analyses employing new structural equation modelling approaches to comparing the latent mean differences indicated that there were differences (although surprisingly small) between the two groups that were generally consistent with a priori predictions. The important educational and clinical implications of these results are discussed.

Fmoc-diphenylalanine self assembles to a hydrogel via a novel architecture based on π-π interlocked β-sheets

The self assembly of peptide hydrogelators that carry aromatic substituents can be modeled by a novel nanocylindrical architecture. The proposed model suggests that the nanocylinders are formed by anti-parallel β-sheets interlocked by the π-stacking interactions of fluorenyl groups and phenyl rings. This explanation is consistent with the structures observed in TEM and the data obtained by a variety of spectroscopic techniques.

Measurement issues in the evaluation of chronic disease self-management programs

Objectives: 

A systematic review of outcomes of chronic disease self-management interventions

Purpose
To carry out a systematic review of program outcomes used in the evaluation of group-based self-management interventions aimed at people with arthritis and other chronic conditions.

Methods
The systematic search was performed across databases MEDLINE, EMBASE, CINAHL, and PsycINFO. Both between-group and within-group effect sizes (ES) were calculated. Results were interpreted as small (ES ~ 0.2), medium (ES ~ 0.5), or large (ES ~ 0.8) effects.

Results
The majority of 18 included trials investigated the effectiveness of arthritis-specific interventions. Across most outcomes, small effects on course participants were shown. While effects on knowledge were large (between-group ES = 0.78), effects on clinical outcomes such as pain (ES = 0.10) were negligible to small.

Conclusions
This paper is consistent with other reviews in this area, suggesting that people with arthritis receive only marginal benefits from participating in chronic disease self-management interventions. When looking at the types of outcomes that trials are based on, however, alternative explanations for these results seem probable. As evaluations heavily rely on patient self-report, current approaches to program evaluation may not be sufficient to assess the intended impact of self-management education. An in-depth investigation of the types of outcomes assessed is provided in a separate paper.

Monitoring athletes through self-report: factors influencing implementation

Monitoring athletic preparation facilitates the evaluation and adjustment of practices to optimize performance outcomes. Self-report measures such as questionnaires and diaries are suggested to be a simple and cost-effective approach to monitoring an athlete’s response to training, however their efficacy is dependent on how they are implemented and used. This study sought to identify the perceived factors influencing the implementation of athlete self-report measures (ASRM) in elite sport settings. Semi-structured interviews were conducted with athletes, coaches and sports science and medicine staff at a national sporting institute (n = 30). Interviewees represented 20 different sports programs and had varying experience with ASRM. Purported factors influencing the implementation of ASRM related to the measure itself (e.g., accessibility, timing of completion), and the social environment (e.g., buy-in, reinforcement). Social environmental factors included individual, inter-personal and organizational levels which is consistent with a social ecological framework. An adaptation of this framework was combined with the factors associated with the measure to illustrate the inter-relations and influence upon compliance, data accuracy and athletic outcomes. To improve implementation of ASRM and ultimately athletic outcomes, a multi-factorial and multi-level approach is needed.

Fear of self, doubt and obsessive compulsive symptoms

BACKGROUND AND OBJECTIVES: Following observations in the literature that obsessions often contain or imply negative evaluative information about the self, Aardema et al. (2013) recently developed a measure of feared-self relevant to OCD. The current study aimed to provide further examination of the relevance of such feared self-beliefs to obsessive compulsive processes - in particular whether they partially underlie doubt in OCD-relevant situations. METHOD: Nonclinical participants (N = 463; 291 females; Mage = 25.17, SD = 7.47), were presented with three vignettes, related to washing, checking and non-OCD relevant themes, which assessed doubt through providing alternating sensory and possibility-based information. RESULTS: Higher levels of OCD symptoms and feared-self beliefs both significantly predicted both higher baseline levels of doubt and greater fluctuation in levels of doubt in both the contamination and checking scenarios, and to a much lesser extent in the control scenario. Feared-self beliefs did not predict fluctuation in doubt over-and-above OCD symptoms, consistent with a mediation model. LIMITATIONS: The main limitation was the use of a non-clinical sample, although this allowed sufficient participant numbers to test hypotheses. CONCLUSIONS: The findings provided further experimental support for reasoning processes in OCD, and suggested that feared self-beliefs may make individuals vulnerable to experiencing doubt. Additionally, these results suggested that individuals with high OCD symptoms and those with high feared self-beliefs are unable to recognise the improbable nature of possibility-based statements. Implications for treatment and theory are discussed.

Improving laboratory learning through self and peer assessment of laboratory reports

The laboratory provides an opportunity for students to achieve many learning outcomes including to critically evaluate information, interpret and draw conclusions from scientific data, and communicate scientific results, information, or arguments. This paper describes a laboratory-writing task that involves self and peer evaluation. After discussion of the expectations of laboratory report writing during class, students self and peer evaluate reports. In a process similar to double-blind journal refereeing, students practise critically evaluating the quality of academic writing using a rubric. The summative assessment is based on how consistent their evaluations are with the evaluations of the same reports performed by their peers. The formative assessment is that students receive peer evaluations and feedback via a rubric on reports that they have written. The skill of critically evaluating their own reports is used to improve the laboratory reports in subsequent assessment tasks.

Shedder status— An analysis of self and non-self DNA in multiple handprints deposited by the same individuals over time

There are several studies that suggest that different people deposit different quantities of their own DNA on items they touch, i.e. some are good shedders and others are bad shedders. It is of interest to determine if individuals deposit consistent quantities of their own DNA, no matter the occasion, as well as the degree of variability among individuals. To investigate this, participants were tested for their ability to deposit DNA by placing right and left handprints on separate DNA-free glass plates at three set times during the day (morning, midday and afternoon) on four different days spaced over several weeks. Information regarding recent activities performed by the individual was recorded, along with information on gender, hand dominance and hand size. A total of 240 handprint deposits were collected from 10 individuals and analyzed for differences in DNA quantity and the type of the DNA profile obtained at different times of the day, on different days, between the two hands of the same individual, and between different individuals. Furthermore, the correlation between the deposit quantity and the ratio of self to non-self DNA in the mixed deposits was analyzed to determine if the amount of non-self DNA has an effect on overall DNA quantities obtained. In general, this study has shown that while there is substantial variation in the quantities deposited by individuals on different occasions, some clear trends were evident with some individuals consistently depositing significantly more or less DNA than others. Non-self DNA was usually deposited along with self DNA and, in most instances, was the minor component. Incidents where the non-self portion was the major component were very rare and, when observed, were associated with a poor depositor/shedder. Forensic DNA scientists need to consider the range and variability of DNA a person deposits when touching an object, the likelihood of non-self DNA being co-deposited onto the handled object of interest and the factors that may affect the relative quantity of this component within the deposit.

An extended approach to adjust inconsistent minority peer- and self-assessment scores of teamwork using assessor’s reliability

Teamwork is generally assessed either solely by academic staff or by both academic staff andstudents themselves confidentially as well as collaboratively. Peer- and self-assessments have beenused primarily to assess teamwork process and teacher assessment to assess teamwork product.Peer- and self-assessments are useful to elicit team members’ contribution towards teamwork and toconvert team mark into individual marks, provided the scores are reliable (the extent to which thescores are consistent). However, not all peer- and self-assessment scores are reliable. Anecdotal andliterature evidence suggest that there are several cases of inconsistencies in these scores. Individualcontribution scores given by teammates to an assessee (including himself/herself) can sometimesvary significantly due to both intentional and unintentional reasons. Simply using total individual ratingscores without considering an assessor’s reliability to estimate individual contribution factors cansometime results unfair grades and becomes hindrance to learning through teamwork.PURPOSEThis study proposes an extended approach to adjust inconsistent and/or distorted minority peer andself-assessment scores of teamwork using standard normal probability concept.APPROACHIn order to adjust inconsistent and/or distorted minority peer-and self-assessment scores of teamwork,an extended approach has been proposed. The approach uses the reliability of assessor’s scores ofan assessee using standard normal probability curve. The evaluation of the extended approach isconducted by comparing with the existing approaches using two case examples of peer- and selfassessmentof teamwork where minority team members’ scores are inconsistent.RESULTSThe evaluation of the extended approach shows that the proposed method is superior to the availableapproaches in order to adjust inconsistent peer- and self-assessment scores for special cases wherescores of minority team members are inconsistent. The extended approach helps both to automaticallydetect such scoring anomalies and to adjust the scores so that the fairer contributions to the teamworkwould be obtained and utilised.CONCLUSIONSThe extended approach is useful in that it helps both to automatically detect scoring anomalies and todevise the methods to adjust them. However, the approach does not address the issue of scoringinconsistencies by majority of team members as it uses average score as a basis for identifyinginconsistencies. Moreover, the approach needs to be implemented in the real teamwork environmentin order to identify the impacts of these scoring adjustments in teamwork process and teamworkproduct.
