The Effectiveness of Warning Labels for Consumers: A Meta-Analytic Investigation into Their Underlying Process and Contingencies

Although several meta-analyses have been conducted on the effectiveness of warning labels, many questions regarding their effectiveness remain unanswered. The authors identify 243 effect sizes from 66 primary articles, more than three times the number of effect sizes included in the most comprehensive meta-analysis to date. This updated and substantially larger data set shows that label effectiveness is contingent on the type of expected behavioral outcome. Labels aimed at moderation/cessation display a generally diminishing cascade of effects from attention (r = .32), comprehension (r = .37), recall (r = .31), judgment (r = .22), and behavior (r = .18). Labels targeting safe use show stronger effect sizes for behavior (r = .39) despite displaying a downward trend for attention (r = .35), comprehension (r = .29), recall (r = .32), and judgment (r = .21). The authors also find evidence of increased effectiveness when preactivating the label by means of an integrated communication strategy (r = .49). In addition, the results show the impact of several contextual factors (e.g., social influence [r = .33] and exposure frequency [r = .12]).

Debates and assumptions about motion picture performance: a meta-analysis

Abstract Across the many studies of motion picture box office success, unresolved debates and untested assumptions about the contributing factors persist. Using an accessibility–diagnosticity framework and a meta-analysis of 634 effect sizes from 150 studies, the current article seeks to clarify the relationships of star brand equity and product reviews (from consumers and critics) with box office success. The popularity of stars (market and media appeals) exerts a stronger impact on box office success than their artistic recognition (as per award nominations and wins) at the moment of a movie’s release but not over its extended theatrical run. Whereas the impact of popular stars on box office success decreases over time, the influence of artistically recognized stars remains steady. The findings also identify a dual role for critics, who influence consumers’ movie choice and predict box office performance by merely reflecting moviegoers’ tastes. Finally, this study refutes the assumption that the impact of users’ reviews strengthens over time, relative to critics’ reviews.

Smartphone withdrawal creates stress: A moderated mediation model of nomophobia, social threat, and phone withdrawal context

Abstract A growing body of literature demonstrates that smartphone use can become problematic when individuals develop a technology dependency such that fear can result. This fear is often referred to as Nomophobia, denoting the fear of not being able to use ones phone. While the literature (especially on technostress and problematic smartphone use) has shed ample light on the question of which factors contribute to the development of Nomophobia, it remains less clear how, why, and under what conditions Nomophobia, in turn, results in negative consequences, especially stress. Drawing on the demand-control-person model, this study develops a novel research model indicating that Nomophobia impacts stress through the perception of a social threat and that this indirect effect depends on the context of a phone withdrawal situation. Data collected from 270 smartphone users and analyzed using multi-group path analysis supported our model. The results showed that the proposed indirect effect is non-significant only when situational certainty and controllability come together, that is, when people know for how long they will not be able to use their phones and when they have control over the situation. Managers can help their nomophobic employees by instilling in them trust and perceptions of social presence while also giving them more control over their smartphone use during meetings.

When Your Best Customers Become Your Worst Enemies: Does Time Really Heal all Wounds?

Abstract Customer revenge and avoidance in the context of online complaints by the public are hot topics. This article helps managers to understand the phenomenon and to prevent damage. Do online complainers hold a grudge-in terms of revenge and avoidance desires-over time? Results show that time affects the two desires differently: although revenge decreases over time, avoidance increases over time, indicating that customers hold a grudge. Then, we examine the moderation effect of a strong relationship on how customers hold this grudge. Indeed firms’ best customers have the longest unfavorable reactions. This is called the love-becomes-hate effect. Specifically, over time the revenge of strong-relationship customers decreases more slowly, and their avoidance increases more rapidly, than for weak-relationship customers. Further, we explore a solution to attenuate this damaging effect: the firm offering an apology and compensation after the online complaint. Overall, strong-relationship customers are more amenable to any level of recovery attempt.
