<p>The study of change in repeated measures studies or longitudinal studies (cross-sectional and/or cross-sequential) is of considerable interest in the field of developmental psychology. Qualitative and quantitative measures of interindividual and intraindividual variability can be used to capture changes in cognitive development.</p><p>In the present study, through an empirical analysis of infant cognitive development, we investigate whether or not longitudinal (cross-sectional/cross-sequential) research designs can be used interchangeably with univariate or multivariate data analysis techniques. Methodologically, longitudinal data can be processed by univariate or multivariate analysis. However, the results and their interpretation may be different, even when the necessary statistical requirements are performed. Current statistical programs incorporate techniques to test for the presence of significant differences in data, regardless of whether these are evaluated by univariate or multivariate analysis.</p>The results of this study, conducted in infants studied at three time points (18, 21 and 24 months), show that both intraindividual and interindividual variability can be detected by repeated measures analyses.

AbstractStudies that distinguish the role of dispositional and situational moral emotions in bullying situations remain limited in the international literature. This work, therefore, aims to analyze the role of dispositional and situational moral emotions in bullying and prosocial behavior in adolescents. Two studies were conducted: a cross-sectional study including 644 adolescents aged 14–18 years (M = 15.6, DT = 1.4) and a repeated measures design including 235 adolescents aged 10–15 years (M = 12.5, DT = 0.9). The objectives of Study 1 were 1) to validate two scales for the situational moral emotions elicited in bullying situations (elevation and moral disgust) and 2) to examine the relationships between dispositional and situational moral emotions and prosocial behavior toward victims and bullying behavior. The results show adequate psychometric properties for both elevation and moral disgust scales. Furthermore, both situational moral emotions are negatively related to bullying behavior, whereas dispositional emotions such as compassion and gratitude have a positive effect on prosocial behavior. Study 2 assessed the prospective relationship between dispositional gratitude and prosocial behavior toward victims and bullying behavior. The results of this study indicate that dispositional gratitude has a positive prospective effect on prosocial behavior towards victims and a negative effect on bullying behavior. In conclusion, the relevance of moral emotions for the prevention of bullying behavior is highlighted and the role that self-transcendent dispositional emotions have on prosocial behavior from the perspective of developmental psychology.

Abstract Objective Rating tissue irritability has been recommended to aid decision making in several recent clinical practice guidelines. An explicit method for rating tissue irritability was proposed as part of the Staged Algorithm for Rehabilitation Classification: Shoulder Disorders (STAR-Shoulder), but the reliability and validity of this classification are unknown. The purpose of this study was to examine the reliability and concurrent validity of shoulder tissue irritability ratings as part of a system designed to guide appropriate treatment strategy and intensity. Methods A clinical measurement, prospective repeated-measures cross-sectional design was used. The 101 consecutive participants with primary complaints of shoulder pain were assessed by pairs of blinded raters (24 raters in total) and rated for tissue irritability. Patients completed 3 patient-rated outcome (PRO) measures reflecting both pain and disability, and these scores were compared with ratings of tissue irritability. Paired ratings of irritability were analyzed for reliability with prevalence-adjusted, bias-adjusted Kappa for ordinal scales (PABAK-OS). Analysis of variance (ANOVA) was used to compare PRO measures across different levels of irritability. Receiver operating characteristic (ROC) curve analysis was utilized to derive cut-off scores for 3 PRO instruments. Results Interrater reliability was 0.69 (95% CI = 0.59–0.78), with 67% agreement. All PRO measures were significantly different among 3 levels of tissue irritability. Conclusion There appear to be acceptable reliability and a strong relationship between PRO measures and therapist-rated tissue irritability, supporting the use of the STAR-Shoulder irritability rating system. Impact Several clinical practice guidelines have recommended that clinicians rate tissue irritability as part of their examination. This study provides important new information supporting the reliability and validity of the STAR-Shoulder tissue irritability rating system.

Intersectional research on childhood suicidality requires studies with a reliable and valid measure of suicidality, as well as a large sample size that shows some variability of suicidality across sex by race intersectional groups. Objectives: We aimed to investigate the feasibility of intersectionality research on childhood suicidality in the Adolescent Brain Cognitive Development (ABCD) study. We specifically explored the reliability and validity of the measure, sample size, and variability of suicidality across sex by race intersectional groups. Methods: We used cross-sectional data (wave 1) from the ABCD study, which sampled 9013 non-Hispanic white (NHW) or non-Hispanic black (NHB) children between the ages of 9 and 10 between years 2016 and 2018. Four intersectional groups were built based on race and sex: NHW males (n = 3554), NHW females (n = 3158), NHB males (n = 1164), and NHB females (n = 1137). Outcome measure was the count of suicidality symptoms, reflecting all positive history and symptoms of suicidal ideas, plans, and attempts. To validate our measure, we tested the correlation between our suicidality measure and depression and Child Behavior Checklist (CBCL) sub-scores. Cronbach alpha was calculated for reliability across each intersectional group. We also compared groups for suicidality. Results: We observed some suicidality history in observed 3.2% (n = 101) of NHW females, 4.9% (n = 175) of NHW males, 5.4% (n = 61) of NHB females, and 5.8% (n = 68) of NHB males. Our measure’s reliability was acceptable in all race by sex groups (Cronbach alpha higher than .70+ in all intersectional groups). Our measure was valid in all intersectional groups, documented by a positive correlation with depression and CBCL sub-scores. We could successfully model suicidality across sex by race groups, using multivariable models. Conclusion: Given the high sample size, reliability, and validity of the suicidality measure, variability of suicidality, it is feasible to investigate correlates of suicidality across race by sex intersections in the ABCD study. We also found evidence of higher suicidality in NHB than NHW children in the ABCD study. The ABCD rich data in domains of social context, self-report, schools, parenting, psychopathology, personality, and brain imaging provides a unique opportunity to study intersectional differences in neural circuits associated with youth suicidality.

Purpose: The purpose of this study was to evaluate the psychological distress of urological and uro-oncological patients undergoing surgery. Methods: Patients who presented to Mercy University Hospital from October 2019–May 2020 were consecutively recruited. Demographic and clinical characteristics including age, gender, marital status, type of surgery (uro-oncology or general urology), endoscopy or open surgery were gathered. Mood was evaluated using the Hospital Anxiety and Depression Scale prior to admission, prior to discharge and 6 weeks post-surgery. Results: A total of 118 participants (79.7% male) completed the Hospital Anxiety and Depression Scale prior to admission, prior to discharge and at 6 weeks post-surgery. Forty patients (33.9%) underwent uro-oncology-related surgery. At pre-admission 39 patients (33%) fell into a possible-probable clinical category for anxiety and 15 (12.7%) for depression. Older patients had significantly lower anxiety levels than younger patients ( p⩽0.01). There were no differences between patients undergoing uro-oncology or more general urology surgery and levels of anxiety or depression. Repeated measures analysis of variance with age as a covariate indicated no significant differences in Hospital Anxiety and Depression Scale anxiety scores over time. There was a statistically significant reduction in Hospital Anxiety and Depression Scale depression scores over the three assessment time points ( p=0.004). Conclusion: Over one-third of patients were experiencing moderate to severe levels of psychological distress pre-surgery – higher than levels previously reported in uro-oncological patients. Surprisingly, there was no difference in anxiety and depression scores in uro-oncology and urology patients. Psychological distress in both uro-oncology and more general urology patients should be considered in the surgical setting. Level of evidence Moderate

Leadership is a process whereby an individual influences a group of individuals to achieve a common goal (Northhouse, 2011). In time and space, women leadership remains a subject talked about but hardly appreciated (Wren, 2013). Among the factors contributing to poor representation of women in leadership is stakeholder’s attitude (Coleman, 2005). The study sought to investigate stakeholder’s attitudes impeding women teachers' ascension to leadership positions in mixed public secondary schools, focusing in Tharaka South Sub – County, Kenya. The study employed descriptive cross-sectional survey design utilizing both qualitative and quantitative methods of data collection. Probability and non-probability sampling techniques were used to arrive at the sample size. Data was collected from women classroom teachers, heads of departments, school principals, education officers, education trade unionists, Parents and Teachers Association officials and School Board of Management officials. Questionnaires, interview guide and focus group discussion guides were used to collect both qualitative and quantitative data. Data analysis was assisted by computer software (Statistical Package for Social Sciences for quantitative data and NVIVO for qualitative data). The study established that education stakeholders have a general negative attitude towards women leadership in schools.

BACKGROUND: The qualitative and quantitative scientific output of Brazilian dermatologists in journals of high impact factor is little known. OBJECTIVE: To describe the scientific output of dermatologists from Brazilian institutions in journals of high impact factor. METHODS: The five journals with the highest impact factor in dermatology were analyzed. All articles produced from Brazilian institutions between 1986 and 2010 were compiled and the following aspects were analyzed: position of Brazilian researchers in the list of authors, selected theme, experimental design, studied disease, area of interest and year of publication. RESULTS: Seventy-four articles written with the participation of Brazilian dermatologists have been identified. Upon grouping the articles in five-year periods, an important increase was observed in the Brazilian production from the year 2006 onwards. The dermatologists were placed as second authors in the majority of cases (53.66%). According to the selected theme to be studied, the majority of the articles had a laboratory focus (45.95%). The majority of the articles reported cross-sectional studies or non-controlled clinical trials (both at 17.57%), and pemphigus foliaceus was the most studied disease (29.73%). CONCLUSION: The increase in the number of publications by Brazilian dermatologists over the last years is encouraging, but it is still small in comparison to the total number of articles published in these five periodicals.

The Impact

Purpose – The purpose of this paper is to investigate client influence on mortgage valuation in Nigeria to establish and rank the means of influence clients employ, and the impact of firm characteristics on client influence. Design/methodology/approach – A combination of cross-sectional survey and focus groups research designs was adopted. Questionnaire structured on five-point Likert format was used to collect data from a sample of valuation firms in five Nigerian cities. Descriptive statistics, χ2, and moderated hierarchical linear model were used for data analysis. Findings – Clients’ means of influence on valuation are more of subtle approach than threat or coercion. The most prevalent means are respectively, plea for assistance, promise of continued retainership on banks’ valuer panels, and disclosing the loan amount. Client influence differs across cities; firm characteristics have no influence on client pressure. Practical implications – The research provides basis for valuation bodies to review practice rules and standards and seek for legislation for valuer independence. It can serve as material for teaching and training in professional ethics. Social implications – Biased valuations jeopardises credit risk mitigation process with potential for destabilising banks, finance sector, and consequences for the economy. Originality/value – The study provides empirical evidence of the nature of client influence across several major Nigerian cities. In contrast to existing Nigerian studies that focus on single cities, the study covers several cities. It therefore provides a broad basis for problem-solving and decision-making.
