Iacobucci (2009, 2010) covers a number of important issues in the use of structural equation modeling and in so doing provides researchers with many useful insights and sensible suggestions. This commentary focuses on three issues where our views differ somewhat from those expressed in the target articles: SEM and causal inferences, sample size, and model fit. In addressing each of these issues, our perspectives do not so much contradict the views expressed by Iacobucci as they reflect a somewhat different conceptual emphasis. 相似文献

School bonding refers to the connections that youth have with their schools and various aspects of their academic lives. School bonding may be an important concept in prevention because it has been linked to various developmental and adjustment outcomes. This paper reviews conceptualizations, measurements, and theories of school bonding. Also considered are empirical studies that have linked school bonding to a variety of outcomes (substance use, delinquency, antisocial behavior, self-esteem). The review includes examination of how school bonding serves as a mediator in these relations and, in turn, is moderated by other variables. Despite inconsistencies in conceptualization and measurement, it is concluded that school bonding is an important construct and an appropriate target for intervention. Recommendations are offered regarding future research on school bonding, especially with respect to positive developmental outcomes and examination of variables that might moderate school bonding. 相似文献

There seem to be two competing streams of thought about the use of theory in the marriage and family therapy literature: theoretical purity versus integrationism. We examined influence of theoretical orientation on client experience in therapy. Level of academic training (masters' versus doctoral degree) was investigated as a possible confounding variable. Results suggest that therapists in private practice are less inclined to practice pure forms of therapy. 相似文献

Standard chi-square-based fit indices for factor analysis and related models have a little known property: They are more sensitive to misfit when unique variances are small than when they are large. Consequently, very small correlation residuals indicating excellent fit can be accompanied by indications of bad fit by the fit indices when unique variances are small. An empirical example of this incompatibility between residuals and fit indices is provided. For illustrative purposes, an artificial example is provided that yields exactly the same correlation residuals as the empirical example but has larger unique variances. For this example, the fit indices indicate excellent fit. A theoretical explanation for this phenomenon is provided using relationships between unique variances and eigenvalues of the fitted correlation matrix. 相似文献

This issue of Clinical Child and Family Psychology Review, Children Exposed to Community Violence or War/Terrorism: Current Status and Research Directions, addresses the current status of our knowledge as well as critical research needs in the area of children exposed to violence outside the family. Although much has been learned in recent years about children exposed to violence, significant research gaps remain, the identification of which may help to build a more complete and rigorous science base in this area. This journal issue represents the distillation of a 3-day workshop on children exposed to violence, held in July of 2002, that identified what is known about children exposed to violence and what this information tells us about future research directions. Although many federal agencies have supported some research in this area, there is a need for more targeted attention on the topic, particularly with regard to measurement, sampling, and interventions/services. The papers in this issue were selected with these themes in mind. Although no single issue could cover the entire field, we intend to offer a representative sample of where we are and where we need to go with the hope of stimulating additional thought, collaboration, and research in this important area. 相似文献

The aims of this study were two-fold: (i) to examine the validity of the proposed three-factor structure (intention, action-, and coping planning) in an Iranian sample of adolescents, and (ii) to assess the predictive ability of the Theory of Planned Behavior (TPB) measures of action planning and coping planning for dental brushing. Eight hundred adolescents were randomly selected to participate in the study. 90% (721) of adolescents agreed to participate. Perceived behavioral control, action and coping planning scales and a self-report questionnaire related to dental brushing behavior were completed by the adolescents at baseline. One month later (time-point 2), the adolescents were asked to reassess their frequency of dental brushing over the four week period. Data were analyzed by a confirmatory factor analysis (CFA) on an original three-factor structure (intention, action plan, and coping plan). A hierarchical linear regression analysis was also performed. The CFA for the original three-factor structure showed a good fit index (χ(2)?=?637.60, degrees of freedom df?=?116), goodness-of-fit index (GFI)?=?91, and root mean square error of approximation (RMSEA)?=?0.079. Adjusting for demographic variables, action- and coping planning together accounted for 7.9% of the variance associated with dental brushing behavior at one month. In conclusion, results suggest that action planning and coping planning are associated with higher frequency in dental brushing among Iranian adolescents. 相似文献

We examine main and interaction effects of organizational justice at the individual and the organizational levels on general health in a Kenyan sample. We theoretically differentiate between two different interaction patterns of justice effects: buffering mechanisms based on trust versus intensifying explanations of justice interactions that involve psychological contract violations. Using a two‐level hierarchical linear model with responses from 427 employees in 29 organizations, only interpersonal justice at level 1 demonstrated a significant main effect. Interactions between distributive and interpersonal justice at both the individual and the collective levels were found. The intensifying hypothesis was supported: the relationship between distributive justice and mental health problems was strongest when interpersonal justice was high. This contrasts with buffering patterns described in Western samples. We argue that justice interaction patterns shift depending on the economic conditions and sociocultural characteristics of employees studied. 相似文献

For each of 75 Ss several estimates of intra-individual variations were calculated for each of 4 motor skills. The reliability of intra-individual variation for these data, estimated from Pearson productmoment correlations, ranged from r = .31 to r = .51 (in all cases p < .05). It was also found that in 3 of the 4 skills, intra-individual variation correlated significantly (r = .36, .54, .55) with mean performance level. Second order partial correlations, holding constant the effect of mean performance level, were then used to estimate the reliability of intravariation. These correlations were statistically significant and ranged from r = .27 to r = .34. When correlations of intra-individual variation were calculated among the four skills it was demonstrated that intra-individual variation was approximately 95 to 100% task specific. 相似文献

Praise and other forms of attention may not function as reinforcers for the behavior of children with autism. Previous research demonstrated that contingently pairing praise with reinforcers (response stimulus) can establish praise as a conditioned reinforcer. We evaluated a procedure for establishing praise as a generalized conditioned reinforcer (pair praise with four reinforcers) and compared it with a procedure to establish praise as a conditioned reinforcer (pair praise with one reinforcer). We compared the two conditions in a reversal design with “praise” and “no programmed consequence” conditions rapidly alternated after pairing phases. With three out of five participants with autism, responding in the “pair‐with‐four” condition showed higher levels of responding or more increasing trends compared with that in “pair‐with‐one” condition. We also replicated previous contingent pairing research with two participants in a multiple baseline across participants design. A limitation was the absence of manipulating motivating operations in assessing the efficacy of praise as a generalized conditioned reinforcer. Nevertheless, these data contribute to the research on establishing praise as a reinforcer, and we recommend directions for future research. 相似文献

The purpose of this study is to propose a new perspective on classifying or segmenting consumers by describing a minority of them who are uniquely motivated by high levels of status seeking, brand identification, and materialism. We term this segment of individuals “super consumers.” The data came from an online survey of 351 adult US consumers. A cluster analysis using these three variables as criteria produced a two‐cluster solution. Comparing mean scores between these two groups of consumers on measures of market mavenism, shopping frequency, amount of spending, age, and gender showed that the super consumers were significantly more likely to be market mavens, to shop more frequently, and to spend more than the other consumers were. The super consumers were younger in age as well, but there were no gender differences between the two groups. Copyright © 2015 John Wiley & Sons, Ltd. 相似文献
