Factors influencing self‐report of mobile phone use: the role of response prompt,time reference and mobile phone use in recall

The current study (n = 180) assesses factors affecting the recall of past mobile phone behaviour. It manipulates two factors hypothesised as influencing recall of duration and number of calls made: time reference (24 hours vs. 3 days) and context prompt (temporal, person called, reason for call) and also considers their impact in relation to levels of mobile phone use. A measure of recall error was constructed by matching self‐reported calls to actual calls and weighting for actual usage. The results indicate that most people tend to overestimate duration and underestimate number of phone calls, although these discrepancies are related to actual amount of mobile phone use. The manipulations of time reference and context prompt have some effect on the patterns of recall in relation to number, rather than duration, of calls. The implications of these results for the development of reliable and valid self‐report measures of mobile phone use are discussed. Copyright © 2008 John Wiley & Sons, Ltd.     

Improving Prediction of Work Performance Through Frame‐of‐Reference Consistency: Empirical evidence using openness to experience

A work‐specific measure of openness to experience was compared with the general NEO PI‐R Openness scale for predicting supervisory ratings of creative performance at work. Results at the scale and facet levels indicated that the use of a consistent and criterion‐matched frame of reference improved validity of this personality construct for the prediction of work‐related creative problem solving. Scores from the Work‐specific Openness scale significantly predicted creative work performance, whereas scores from the general measure did not. Results also showed incremental validity of the Work‐specific scale over the NEO PI‐R scale. Evidence is mounting that specifying a work context for personality measures can increase validity for predicting job performance beyond that typically observed when using general scales.

Treatment of Missing Data: Beyond Ends and Means

The ethical decision making process behind the treatment of missing data has yet to be examined in the research literature in any discipline. The purpose of the current paper is to begin to discuss this decision-making process in view of a Foucauldian framework. The paper suggests how the ethical treatment of missing data should be considered from the adoption of this theoretical framework.     

Influence analysis for the factor analysis model with ranking data

Influence analysis is an important component of data analysis, and the local influence approach has been widely applied to many statistical models to identify influential observations and assess minor model perturbations since the pioneering work of Cook (1986) . The approach is often adopted to develop influence analysis procedures for factor analysis models with ranking data. However, as this well‐known approach is based on the observed data likelihood, which involves multidimensional integrals, directly applying it to develop influence analysis procedures for the factor analysis models with ranking data is difficult. To address this difficulty, a Monte Carlo expectation and maximization algorithm (MCEM) is used to obtain the maximum‐likelihood estimate of the model parameters, and measures for influence analysis on the basis of the conditional expectation of the complete data log likelihood at the E‐step of the MCEM algorithm are then obtained. Very little additional computation is needed to compute the influence measures, because it is possible to make use of the by‐products of the estimation procedure. Influence measures that are based on several typical perturbation schemes are discussed in detail, and the proposed method is illustrated with two real examples and an artificial example.     

Active school travel is associated with fewer suicide attempts among adolescents from low-and middle-income countries

Background/Objective: This study explored the association between active school travel (AST) and suicide attempts among adolescents in low- and middle-income countries (LMICs). Method: We used the data from the Global School-based Health Survey, including 127,097 adolescents aged 13-17 years from 34 LMICs. A self-reported survey was used to collect data on AST and suicide attempts as well as some variables. Multivariable logistic regression was performed to assess the association between AST and suicide attempts. A meta-analysis with random effects was undertaken to identify the difference in the association between AST and suicide attempts. Results: Across all the adolescents, the prevalence of AST was 37% and the prevalence of suicide attempts was 11.60%. Adolescents who engaged in AST were less likely to have suicide attempts irrespective of gender. The country-wise analysis indicated a large inconsistency in the association between AST and suicide attempt across the countries. Conclusions: AST would appear to be a protective factor for reducing suicide attempts among adolescents. However, the association between AST and suicide attempts varied greatly across the countries. Future studies should confirm the association between AST and suicide attempts.     

The Spotlight Effect Revisited: Overestimating the Manifest Variability of Our Actions and Appearance

Three studies examined people's estimates of the perceived variability of their appearance and behavior in the eyes of others. Whether assessing the manifest variability of their physical appearance (Studies 1a, 1b, and 1c), their athletic accomplishments (Study 2), or their performance on a popular videogame (Study 3), participants consistently overestimated the extent to which their ups and downs would be noted by observers. The results of Study 3 suggest that this bias stems in part from a failure to appreciate the extent to which observers are preoccupied with managing their own actions. Discussion focuses on how this corollary of the “spotlight effect” can contribute to social anxiety and gnawing regrets of inaction.     

Facial Expressions of Emotion: Are Angry Faces Detected More Efficiently?

The rapid detection of facial expressions of anger or threat has obvious adaptive value. In this study, we examined the efficiency of facial processing by means of a visual search task. Participants searched displays of schematic faces and were required to determine whether the faces displayed were all the same or whether one was different. Four main results were found: (1) When displays contained the same faces, people were slower in detecting the absence of a discrepant face when the faces displayed angry (or sad/angry) rather than happy expressions. (2) When displays contained a discrepant face people were faster in detecting this when the discrepant face displayed an angry rather than a happy expression. (3) Neither of these patterns for same and different displays was apparent when face displays were inverted, or when just the mouth was presented in isolation. (4) The search slopes for angry targets were significantly lower than for happy targets. These results suggest that detection of angry facial expressions is fast and efficient, although does not "pop-out" in the traditional sense.     

Evaluation of a High School Peer Group Intervention for At-Risk Youth

The purpose of this paper is to examine the effectiveness of Reconnecting Youth, a prevention program for at-risk high school youth. Data are from a large, independently evaluated effectiveness trial in two diverse urban school districts. A total of 1,218 students participated; 50% were male; average age was 15. We tested whether positive efficacy trial effects could be replicated, and whether any negative behavioral effects occur when clustering high-risk youth. Although mixed program effects were observed at immediate post-intervention, only negative effects were found at 6-month follow-up. These effects included less optimal scores on measures of GPA, Anger, School Connectedness, Conventional Peer Bonding, and Peer High-Risk Behaviors. Overall, we found little support for the use of this social-influence—model intervention aimed at increasing school connectedness for high-risk youth. Further, this study provides evidence that clustering high-risk youth in preventive interventions has the potential for iatrogenic effects.
