The Satisfaction with Life Scale in Adolescent Samples: Measurement Invariance across 24 Countries and Regions,Age, and Gender

Measurement of adolescent life satisfaction across cultures has not received much attention in previous empirical research. The present study evaluated measurement invariance of the Satisfaction with Life Scale (SWLS) among adolescents in 24 countries and regions (N = 22,710; age range = 13–19 years; 53% female). A single-factor model with residual covariance between a pair of items tapping past life satisfaction fitted well in 19 countries and regions and showed a partial metric invariance. In a subset of nine countries and regions, partial scalar invariance was supported. Partial metric invariance across all 24 countries and regions was achieved when custom model modifications in five countries and regions were included. Three SWLS items showed evidence of noninvariance across cultures. The measurement model was found to operate similarly across gender and age. Our findings suggest that caution is needed when using the SWLS for measuring life satisfaction among adolescents from different cultures.

     

Opinion formation in evaluating the adjudicative competence and restorability of criminal defendants: a review of 8,000 evaluations

Evaluations of competence to stand trial (CST) are the most common type of criminal forensic evaluation conducted, and courts tend to defer to clinician opinions regarding a defendant's competence. Thus, it is important to study the ways in which clinicians arrive at opinions regarding adjudicative competence and the data they consider in forming their opinions. We reviewed 8,416 evaluations conducted by forensic evaluators in Virginia over a 12 year period, and examined (a) the clinical, demographic, and criminal characteristics of a defendant as related to opinions regarding competence, predicted restorability, and impairment on "prongs" of the Dusky standard, (b) process and outcome differences in evaluations conducted by psychiatrists versus psychologists and inpatient versus outpatient evaluators, and (c) the consistency of incompetence base rates over a 10 year period. Overall, clinicians opined that 19% of defendants were incompetent and considered 23% of these unlikely to be restored to competence. Not surprisingly, psychotic and organic/intellectual disorders were most strongly associated with findings of incompetence. However, there were some notable differences between evaluations by psychologists versus psychiatrists and between evaluations conducted in inpatient versus outpatient settings.     

Expertise in Deception Detection Involves Actively Prompting Diagnostic Information Rather Than Passive Behavioral Observation

In a proof‐of‐concept study, an expert obtained 100% deception‐detection accuracy over 33 interviews. Tapes of the interactions were shown to N = 136 students who obtained 79.1% accuracy (Mdn = 83.3%, mode = 100%). The findings were replicated in a second experiment with 5 different experts who collectively conducted 89 interviews. The new experts were 97.8% accurate in cheating detection and 95.5% accurate at detecting who cheated. A sample of N = 34 students watched a random sample of 36 expert interviews and obtained 93.6% accuracy. The data suggest that experts can accurately distinguish truths from lies when they are allowed to actively question a potential liar, and nonexperts can obtain high accuracy when viewing expertly questioned senders.     

“I Am Sorry to Send You SPAM”

A series of studies investigating cultural differences in apology usage in unsolicited email advertising messages (i.e., SPAM) are reported. Study 1 documented that in comparison to American SPAM, a greater percentage of Korean SPAM included apologies. The next five studies (Ns= 516, 3132, 662, 524, 536) tested various explanations for cross‐cultural differences in uses of, and responses to, apologies. Findings indicated that advertising messages containing apologies were not necessarily more effective than advertising messages without apologies. Koreans, however, considered advertising messages with apologies as more credible and normal and exhibited a greater tendency to model other people's apology use than did Americans. Thus, the frequent presence of apologies in Korean unsolicited email advertising is likely to be based on Koreans' modeling behavior (i.e., a greater tendency to follow social norms).     

A Critical Assessment of Null Hypothesis Significance Testing in Quantitative Communication Research

Null hypothesis significance testing (NHST) is the most widely accepted and frequently used approach to statistical inference in quantitative communication research. NHST, however, is highly controversial, and several serious problems with the approach have been identified. This paper reviews NHST and the controversy surrounding it. Commonly recognized problems include a sensitivity to sample size, the null is usually literally false, unacceptable Type II error rates, and misunderstanding and abuse. Problems associated with the conditional nature of NHST and the failure to distinguish statistical hypotheses from substantive hypotheses are emphasized. Recommended solutions and alternatives are addressed in a companion article.     

The Performance of Multivariate Methods for Two-Group Comparisons with Small Samples and Incomplete Data

Abstract

In intervention studies having multiple outcomes, researchers often use a series of univariate tests (e.g., ANOVAs) to assess group mean differences. Previous research found that this approach properly controls Type I error and generally provides greater power compared to MANOVA, especially under realistic effect size and correlation combinations. However, when group differences are assessed for a specific outcome, these procedures are strictly univariate and do not consider the outcome correlations, which may be problematic with missing outcome data. Linear mixed or multivariate multilevel models (MVMMs), implemented with maximum likelihood estimation, present an alternative analysis option where outcome correlations are taken into account when specific group mean differences are estimated. In this study, we use simulation methods to compare the performance of separate independent samples t tests estimated with ordinary least squares and analogous t tests from MVMMs to assess two-group mean differences with multiple outcomes under small sample and missingness conditions. Study results indicated that a MVMM implemented with restricted maximum likelihood estimation combined with the Kenward–Roger correction had the best performance. Therefore, for intervention studies with small N and normally distributed multivariate outcomes, the Kenward–Roger procedure is recommended over traditional methods and conventional MVMM analyses, particularly with incomplete data.     

Values of Children, Parent–Child Relationship, and Social Change in Korea: Indigenous, Cultural, and Psychological Analysis

Les recherches sur les valeurs que les parents attribuent aux enfants se demandent pourquoi les gens décident ou non d’avoir des enfants et s’intéressent au nombre d’enfants qu’ils choisissent d’avoir. On décrit dans la première partie de cet article la relation parents‐enfants traditionnelle, la structure familiale et les changements sociaux qui se sont produits ces cinquante dernières années en Corée du sud. On présente dans la deuxième partie les résultats de l’étude de 1972 sur les valeurs attribuées aux enfants réalisée en Corée du sud (Lee & Kim, 1975). Dans la dernière partie, on expose une recherche empirique sud‐coréenne portant sur un échantillon de 314 jeunes mères et 395 mères plus âgées. Il apparaît que les bénéfices psychologiques sont les raisons majeures qui justifient le choix d’avoir un enfant et que les contraintes personnelles et financières sont les motifs dominants de ne pas en avoir. Ces résultats mettent en défaut les modèles économiques et utilitaires et soulignent l’importance des facteurs psychologiques, relationnels et culturels. Research on parents’ attribution of value to children examines why people decide to have children or not and the number of children they choose to have. In the first part of this paper, the traditional parent–child relationship, family structure, and social changes that have occurred in South Korea during the past 50 years are reviewed. In the second section, the results of the 1972 Values of Children Study conducted in South Korea ( Lee & Kim, 1975 ) are reviewed. In the final section, an empirical study conducted in South Korea with a sample of 314 young mothers and 395 older mothers is reported. The results indicate that psychological benefits are the most important reasons for having a child and personal and financial constraints are the most important reasons for not having a child. These results challenge the economic and utilitarian models and suggest the importance of understanding the psychological, relational, and cultural factors.     

Surfing the implicit wave

Implicit learning was investigated in two experiments involving a complex motor task. Participants were required to balance on a stabilometer and to move the platform on which they were standing to match a constantly changing target position. Experiment 1 examined whether a segment (middle third) that was repeated on each trial would be learned without participants becoming aware of the repetitions (i.e., implicitly). The purpose of Experiment 2 was to determine the relative effectiveness of explicit versus implicit learning. Here, two identical segments were presented on each trial (first and last thirds), with participants only being informed that one segment (either first or last) was repeated. The acquisition results from both experiments indicated large improvements in performance across 4 days of practice, with performance on the repeated segments being generally superior to that on the non-repeated segment. On the retention tests on Day 5, errors on the repeated segment(s) were smaller than those on the random segment(s). Furthermore, in Experiment 2, the errors on the repeated-known segment, although smaller than those on the random segment, were larger than those on the repeated-unknown segment. Interview results indicated that participants were not consciously aware that a segment was repeated unless they were informed. These results suggest that implicit learning can occur for relatively complex motor tasks and that withholding information concerning the regularities is more beneficial than providing this information.
