When moderation is mediated and mediation is moderated

Procedures for examining whether treatment effects on an outcome are mediated and/or moderated have been well developed and are routinely applied. The mediation question focuses on the intervening mechanism that produces the treatment effect. The moderation question focuses on factors that affect the magnitude of the treatment effect. It is important to note that these two processes may be combined in informative ways, such that moderation is mediated or mediation is moderated. Although some prior literature has discussed these possibilities, their exact definitions and analytic procedures have not been completely articulated. The purpose of this article is to define precisely both mediated moderation and moderated mediation and provide analytic strategies for assessing each.     

Expressive suppression and financial risk taking: A mediated moderation model

This research aimed to investigate the relationship between the habitual use of expressive suppression, a type of emotion regulation strategy, and risk taking in the financial domain. It also attempted to further examine gender as a possible moderator of this relationship and to explore the anticipated emotion related to negative potential outcomes as the mechanism behind this moderated effect. Two studies were conducted for these purposes. In Study 1, a total of 657 college students completed a test battery, including both the Emotion Regulation Questionnaire and the Grable and Lytton Risk Tolerance Scale. The results showed that expressive suppression was negatively related to financial risk taking, and gender moderated this relationship. In Study 2, 441 college students took a test battery including both the Emotion Regulation Questionnaire and a financial investment allocation task. The results replicated the findings in Study 1 and indicated that the anticipated emotion related to negative potential outcomes fully mediated the moderated effect of gender in the suppression-financial risk taking association. These findings implied the importance of considering gender differences in the prediction of financial choices from the perspective of emotion regulation.     

The influence of psychological flexibility on work redesign: mediated moderation of a work reorganization intervention

This quasi-experiment tested the extent to which an individual characteristic, psychological flexibility, moderated the effects of a control-enhancing work reorganization intervention in a call center. Results indicated that, compared with a control group, this intervention produced improvements in mental health and absence rates, particularly for individuals with higher levels of psychological flexibility. Findings also showed that these moderated intervention effects were mediated by job control. Specifically, the intervention enhanced perceptions of job control, and hence its outcomes, for the people who received it, especially for those who had greater psychological flexibility. Discussion highlights the benefits of understanding the processes (e.g., mediators, moderators, and mediated moderators) involved in work reorganization interventions.     

Self-construal, mental distress, and family relations: a mediated moderation analysis with Asian American adolescents

The interactive effects between interdependent and independent self-construal on family cohesion and mental distress were examined. Survey responses from 153 Asian American high school students supported the hypothesized moderation of interdependence by independence on family cohesion, which was found to further mediate the relationship between self-construal and mental distress. Specifically, interdependence was positively associated with family cohesion when independence was high and negatively associated with family cohesion when independence was low. Accounting for the mediator effects of family cohesion, mental distress was positively associated with interdependence and more so for those low on independence than those high on independence. The benefits of biculturalism and research implications for the bidimensional conceptualization of self-construal for ethnic minority populations are discussed.

Exchange ideology and member-union relationships: an evaluation of moderation effects

Based on studies of unionized nurses and water workers in the United Kingdom, perceived union support was associated with union commitment, union citizenship behaviors, and intent to quit union membership and switch unions. Instrumentality was less significant as an antecedent of most of these outcomes. In contrast to earlier findings on organization-employee exchange, although accounting for a relatively small percentage of variance, exchange ideology negatively moderated several of the relationships between support and instrumentality, on one hand, and commitment and union citizenship behaviors, on the other.     

Impact evaluation of the family expectations program and moderation by sociodemographic disadvantage

The federal government, through the Administration for Children and Families (ACF), has funded community-based relationship education programs for couples, individuals, and families, with a strong focus on serving economically disadvantaged and racially diverse families. This study evaluated the impact of a 36-hour, workshop-based couple relationship education program that was funded by ACF using a randomized controlled trial (RCT) design and intent-to-treat (ITT) analyses. Participants were 1320 couples who were either expecting a baby or had a baby within the past 3 months, at the time of enrollment. Follow-up surveys were administered 12 months later. Analyses evaluated program impacts on relationship stability, constructive communication, and destructive conflict compared to a no-treatment control group. Analyses showed a statistically significant impact of the program on destructive conflict (d = 0.10) but not on constructive communication (d = 0.06) or stability (d_Cox = 0.10). Based on findings from previous evaluations, we also examined whether participants’ levels of sociodemographic disadvantage moderated these effects. There was significant moderation by sociodemographic disadvantage on constructive communication and destructive conflict, but not on stability. Effects were observed for those at higher levels of sociodemographic disadvantage.     

The moderation of ambivalence on attitude–intention relations as mediated by attitude importance

Attitudinal ambivalence has been found to moderate attitude–intention relations. However, no prior work has investigated the mechanisms by which this moderation effect occurs. The present research attempted to address this issue. Across two studies, there was evidence that an Ambivalence × Attitude interaction was mediated through judgements about attitude importance. Additionally, the present research ruled out the possibility that attitude certainty, a factor that is often found to be positively related to attitude importance, was not responsible for the observed mediating effects of this latter variable. While replicating previous evidence supporting the moderating properties of ambivalence on attitude–intention relations, the current research sheds light on the critical role that attitude importance plays in this relationship.

Validation of a method of assessing socioemotional regulation in preschoolers

IntroductionBased on the model of Yeates et al. (2007), and on behavioural categories included in several measures of emotional abilities or emotional regulation, a new methodological design was conceived to allow eliciting and observing the child's socioemotional regulation, in three interactive contexts (neutral, cooperative, competitive) and his/her abilities in socioemotional problem-solving.MethodThe validation of the new coding grid was derived from the coding of 90 videos about socioemotional behaviours displayed by 30 typically developing preschoolers.ResultsThe agreement of the judges between themselves and the factorial analyses showed the proper internal validity of the grid.ConclusionOur results showed how this design is relevant for assessing the child's socioemotional regulation. The discussion emphasized its advantages and limits for researchers and practitioners.     

Proposal for a new body sway evaluation method

This study is aimed at examining body sway factors for 1107 healthy people aged 16 to 69 years and to propose a practical body sway evaluation method. The center of foot pressure measurement was carried out twice for 1 min. with a 1-min. rest. 30 parameters with high reliability selected from 6 domains (distance, distribution of amplitude, area, velocity, power spectrum, and body sway vector) were summarized objectively into 4 body sway factors (unit time sway, front-back sway, left-right sway, and high frequency band power). Factor scores were calculated by the estimate equation and the total standard scores of parameters with high factor loadings. Considering this result, a total standard score for each factor was classified into 4 percentile categories based on percentile rank. Using this classification criteria, body sway scores for each individual were classified into any of the above 4 domains for each factor. It was confirmed that young adults mainly belong to percentile Categories A and B and the elderly mainly belong to percentile Categories C and D. It was found that a great effect on body sway occurred when an individual's conscious condition changed (contracting a cold or after exercise). In conclusion, the body sway of healthy people can be explained by these 4 sway factors. An evaluation of the body sway pattern using the 4 sway factors may enable us to concretely understand individuals' disorders and abnormal states in addition to changes in body sway that occur with aging.     

Hardiness and stress moderation: a test of proposed mechanisms

High and low hardy male and female undergraduates completed an evaluative threat task that was manipulated to influence appraisals of the task in a manner consistent with hardiness theory. High hardy subjects displayed higher frustration tolerance, appraised the task as less threatening, and responded to the task with more positive and less negative affect than did low hardy subjects. Although all subjects displayed increased heart rate (HR) in response to the experimental task, high hardy men displayed lower HR elevations during the task than did low hardy men. Hardiness did not influence HR responses among women. Manipulations of task appraisal revealed a similar pattern where men in the high hardiness appraisal conditions displayed lower levels of physiological arousal during the task than did men in the low hardiness appraisal conditions. Appraisal manipulations had either no effect or the opposite effect among women.     

The effect of brand anthropomorphism,brand distinctiveness,and warmth on brand attitude: A mediated moderation model

Brand anthropomorphism is one of the most widely used marketing strategies, and numerous studies have confirmed the positive effect of anthropomorphism on consumers' brand attitude. However, anthropomorphism does not always produce positive effects in particular conditions. This study focuses on the interaction effect of brand anthropomorphism and brand distinctiveness on brand attitude and tests the mediating effect of warmth and competence using the Stereotype Content Model. The results of two experiments show that brand anthropomorphism positively predicts consumers' brand attitude, and brand position (distinctiveness vs. popularity) moderates this relationship. Anthropomorphism may improve consumers' attitudes when the brand is positioned to be popular but has no effect on consumers' attitudes when the brand is positioned to be distinctive. Additionally, warmth (not competence) mediates the interaction effect of anthropomorphism and brand position on brand attitude. This study expands the extant knowledge on anthropomorphism and stereotypes in the field of consumption psychology and provides marketers with more rational strategies when applying anthropomorphism in marketing campaigns.     

A novel method for assessing rival models of recognition memory

A general comparison is made between the multinomial processing tree (MPT) approach and a strength-based approach for modeling recognition memory measurement. Strength models include the signal-detection model and the dual-process model. Existing MPT models for recognition memory and a new generic MPT model, called the Multistate (MS) model, are contrasted with the strength models. Although the ROC curves for the MS model and strength model are similar, there is a critical difference between existing strength models and MPT models that goes beyond the assessment of the ROC. This difference concerns the question of stochastic mixtures for foil test trials. The hazard function and the reverse hazard function are powerful methods for detecting the presence of a probabilistic mixture. Several new theorems establish a novel method for obtaining information about the hazard function and reverse hazard function for the latent continuous distributions that are assumed in the strength approach to recognition memory. Evidence is provided that foil test trials involve a stochastic mixture. This finding occurred for both short-term memory procedures, such as the Brown–Peterson task, and long-term list-learning procedures, such as the paired-associate task. The effect of mixtures on foil trials is problematic for existing strength models but can be readily handled by MPT models such as the MS model. Other phenomena, such as the mirror effect and the effect of target-foil similarity, are also predicted accurately by the MPT modeling framework.
