Predicting children's media use in the USA: Differences in cross‐sectional and longitudinal analysis

The purpose of this paper is to examine the predictors of children's media use in the USA, comparing cross‐sectional and longitudinal analyses. Data come from Waves 1 and 2 of the Child Development Supplement (CDS‐I; CDS‐II), a nationally representative sample of American children aged 0–12 in 1997 and 5–18 in 2002. Twenty‐four hour time use diaries are used to assess children's time spent with media (television, video games, computers, and reading). Predictors examined include socio‐demographics, neighbourhood quality, family factors, and other media use. Ordinary least square (OLS) multiple regressions were performed by three age groups (preschoolers, early school age, and preadolescence). The findings suggest that neighbourhood quality, parental limits and family conflict are significant predictors of children's media use within time or over time, but the significance depends on the type of media and child's developmental stage. In addition, children's television viewing and reading habits are formed early in life and reinforced over time. This study is among the first to provide empirical evidence for the effect of early contextual factors on the life course of children's media use from a developmental perspective.     

Sequence learning: response structure and effector transfer.

Two experiments are reported that investigate the response structure and effector transfer of repeated movement sequences. Participants moved a lever to targets sequentially presented on the computer monitor. In Experiment 1 the learning of 10- and 16-element sequences (identical movement pattern) was contrasted. After 1 day of practice the 10-element sequence was organized into fewer subsequences and, thus, performed more rapidly than the 16-element sequence. The imposed organization appeared to be coded in a relatively abstract way, as evidenced by effector transfer that was as good as that on the retention test. In Experiment 2 the 16-element sequence was studied after more extensive practice. By the end of 4 days of practice the participants produced relatively seamless responses void of obvious transitions between subsequences, but the control of the movement was less effector independent than observed earlier in practice. The results suggest that the process of consolidating the sequence, which led to more fluent response production, also resulted in the utilization of effector specific information.     

Self‐Construal Scales Lack Validity

Self‐construal is thought to mediate and explain the effects of culture on a wide variety of outcome variables. A meta‐analysis of published cross‐cultural self‐construal research is reported in this article, and the results across studies suggests that the evidence for the predicted cultural differences is weak, inconsistent, or nonexistent. The results of 3 priming experiments (N = 121, N = 99, and N = 361) suggest that (a) priming does not account for the inconsistent results observed in the meta‐analysis, (b) that scores on a self‐construal scale appear to be measuring trait‐like constructs that are not sensitive to priming, and (c) that measures of self‐construals lack convergent validity. The results of several measurement studies (N = 121, 223, 230, 323, 214, 206, 126, 204, 148, 141, and 150) were inconsistent with the a priori two‐factor measurement model in every case. Self‐construal scales were found to be radically multidimensional and highly unstable within and across cultures. These results lead us to conclude that catastrophic validity problems exist in research involving the use of self‐construal scales in cross‐cultural research.     

Men as Allies: The Efficacy of a High School Rape Prevention Intervention

This study investigated the effects of a Men as Allies‐based intervention on high school students' rape‐supportive attitudes and behaviors. As hypothesized at posttest, the male and female experimental groups demonstrated a significant decrease in rape‐supportive attitudes, which was maintained at follow‐up. Male participants viewed peers' attitudes toward sexual violence as significantly different (worse) from peers' pretest self‐ratings; after intervention, male and female experimental group participants' peer ratings were significantly more accurate.     

A Multimethod Multitrait Validity Assessment of Self‐Construal in Japan,Korea, and the United States

A large number of previous studies have used self‐construal to predict communication outcomes. Recent evidence, however, suggests that validity problems may exist in self‐construal measurement. The current study conducted a multimethod multitrait (Campbell & Fiske, 1959) validation study of self‐construal measures with data (total N= 578) collected in Korea (N= 200), Japan (N= 212), and the U.S. (N= 166). The data showed that the Singelis (1994) Self‐Construal Scale, the Cross, Bacon, and Morris (2000) Relational Interdependent Self‐Construal Scale (RISC), and the Kuhn and McPartland (1954) Twenty Statements Test (TST) lacked convergent and discriminant validity, both pan‐culturally and within each of the three countries included in the study. Scores on the TST were not significantly related to scores on the self‐construal scales, and the various self‐construal measures correlated more highly with measures of communication directness than with alternative measures of the same type of self‐construal. Substantial method effects were also observed. The results were tested for both 2‐ and 3‐dimensional models of self‐construal and for refined scales and scales with all items retained. The results of all analyses were inconsistent with the claim that self‐construal measures are construct valid.     

The (In)validity of Self‐Construal Scales Revisited

This paper offers a critical rejoinder in the discussion concerning the viability of self‐construal scales. It is our contention that the existing data reported in our previous article (Levine et al., 2003) and elsewhere are more than sufficient to justify the conclusion that self‐report scales purporting to measure interdependent and independent self‐construals as 2 orthogonal constructs lack validity. The arguments to the contrary offered by Gudykunst and Lee (2003) and Kim and Raja (2003) are disputed. Additional data (N = 1,013) show that neither age, occupation, sample size, standardization, nor a 2nd‐order structure can account for the problems we documented previously. Although we see potential utility in the self‐construal construct, we believe that the 3 primary scales fail to meet reasonable and accepted social scientific standards. Difficult conceptual problems will need to be solved prior to the development of new and improved measures.
