Concerns about problematic gaming behaviors deserve our full attention. However, we claim that it is far from clear that these problems can or should be attributed to a new disorder. The empirical basis for a Gaming Disorder proposal, such as in the new ICD-11, suffers from fundamental issues. Our main concerns are the low quality of the research base, the fact that the current operationalization leans too heavily on substance use and gambling criteria, and the lack of consensus on symptomatology and assessment of problematic gaming. The act of formalizing this disorder, even as a proposal, has negative medical, scientific, public-health, societal, and human rights fallout that should be considered. Of particular concern are moral panics around the harm of video gaming. They might result in premature application of diagnosis in the medical community and the treatment of abundant false-positive cases, especially for children and adolescents. Second, research will be locked into a confirmatory approach, rather than an exploration of the boundaries of normal versus pathological. Third, the healthy majority of gamers will be affected negatively. We expect that the premature inclusion of Gaming Disorder as a diagnosis in ICD-11 will cause significant stigma to the millions of children who play video games as a part of a normal, healthy life. At this point, suggesting formal diagnoses and categories is premature: the ICD-11 proposal for Gaming Disorder should be removed to avoid a waste of public health resources as well as to avoid causing harm to healthy video gamers around the world.

We greatly appreciate the care and thought that is evident in the 10 commentaries that discuss our debate paper, the majority of which argued in favor of a formalized ICD-11 gaming disorder. We agree that there are some people whose play of video games is related to life problems. We believe that understanding this population and the nature and severity of the problems they experience should be a focus area for future research. However, moving from research construct to formal disorder requires a much stronger evidence base than we currently have. The burden of evidence and the clinical utility should be extremely high, because there is a genuine risk of abuse of diagnoses. We provide suggestions about the level of evidence that might be required: transparent and preregistered studies, a better demarcation of the subject area that includes a rationale for focusing on gaming particularly versus a more general behavioral addictions concept, the exploration of non-addiction approaches, and the unbiased exploration of clinical approaches that treat potentially underlying issues, such as depressive mood or social anxiety first. We acknowledge there could be benefits to formalizing gaming disorder, many of which were highlighted by colleagues in their commentaries, but we think they do not yet outweigh the wider societal and public health risks involved. Given the gravity of diagnostic classification and its wider societal impact, we urge our colleagues at the WHO to err on the side of caution for now and postpone the formalization.

An important assumption of interpersonal theory is that during social interactions the behavior of one person tends to invite complementary behavior from the other person. Past research examining complementarity has usually used either confederates or fictitious interaction partners in their designs and has produced inconsistent results. The current study used observational ratings of behaviors of 158 participants as they interacted with partners across three different dyadic social situations. Randomization tests of hypothesized order relations found that the behaviors exhibited during these interactions tended to occur in a circular pattern predicted by the interpersonal circumplex. These tests also indicated support for Leary's (1957) orientation of the control and affiliation dimensions of the interpersonal circumplex and Carson's (1969) notion that dominant behavior induces submissive responses and friendly behavior encourages friendly responses.

Three studies are presented that demonstrate the psychometric properties and initial validation of the International Personality Item Pool-Interpersonal Circumplex (IPIP-IPC). The IPIP-IPC is a brief 32-item assessment of the interpersonal cirucmplex designed to be used when time is limited or when participants have difficulty understanding the adjective items used in more traditional assessments of the interpersonal circumplex. In Study 1, 501 participants were examined to develop the IPIP-IPC and demonstrate the circular structure of the IPIP-IPC scales and their relation to the five-factor model of personality. Study 2 included 274 participants to reconfirm the circular structure of the IPIP-IPC scales. Finally, in Study 3, 100 participants again reconfirm the circular structure of the IPIP-IPC scales and demonstrate the overlap of the IPIP-IPC with a commonly used assessment of the circumplex: the 64-item Interpersonal Adjective Scale. Overall, the results suggest that the IPIP-IPC provides a relatively short, quick, and valid assessment of the interpersonal circumplex while maintaining many of the psychometric properties of longer assessment tools.

Although links between body image and dieting behaviors have been established among women, little research is available to elucidate relations between these constructs among men. In the present study, we examined relations between men's and women's body image and healthy and unhealthy dieting behaviors. Two hundred and eight participants' (104 men, mean age = 25.88 years; 104 women, mean age = 23.87 years) body perceptions and body satisfaction were assessed using the Contour Drawing Rating Scale. Participants' dieting behaviors were assessed using the Weight Control Behavior Scale and weight status was assessed using body mass index (BMI). Analyses of relations among BMI, body satisfaction, and healthy dieting behaviors revealed a predictable pattern for both men and women; BMI was inversely related to body satisfaction and was positively related to healthy dieting behaviors. Body satisfaction was inversely related to both men's and women's healthy and unhealthy dieting behaviors. Further analyses of the relations between men's and women's body image and unhealthy dieting behaviors suggest different motives for men's and women's participation in these potentially health-compromising weight-management techniques. Results are discussed in terms of their contribution to researchers' understanding of the gendered nature of body image and dieting behaviors.KEY WORDS: body image; dieting; body satisfaction; men; women.Body dissatisfaction and dieting behaviors are conceptualized as normative among adolescent girls and women. However, little research is available to elucidate associations between body image and dieting behaviors among men. An understanding of body image among both men and women is important given reports of the prevalence of people affected by body dissatisfaction and the psychological distress associated with body dissatisfaction

The principle of complementarity asserts that the interpersonal behaviors of interaction partners tend to complement each other by encouraging partners to act similarly in terms of warmth and opposite in terms of dominance. The current study applied Sadler's computer joystick tracking device (originally designed to assess personality perception) to examine complementarity. Sixty‐six unacquainted females were videotaped during an unstructured dyadic interaction, and their warmth and dominance behaviors were coded using the joystick. Results indicated that both partners tended to alter their behaviors in a complementary manner. In addition, partners who complemented each other in terms of warmth tended to like each other more and performed tasks more accurately and quickly than dyads who were not as complementary on this dimension.

This study examined predictors of young women's interest in obtaining cosmetic surgery. The sample investigated was comprised of 101 college undergraduates residing in the northeastern U.S. (M age=19.99, SD=4.79). Participants' weight status (M BMI=24.52, SD=5.69), body dissatisfaction, internalization of media messages, reports of physical appearance teasing, and interest in obtaining cosmetic surgery were assessed. Results indicated that all of the predictors examined were correlated with women's interest in cosmetic surgery. Further, body dissatisfaction mediated the relations between weight status, internalization of media messages, reports of teasing, and women's interest in cosmetic surgery. Findings are discussed in terms of the importance of understanding cosmetic surgery trends and young women's susceptibility to body dissatisfaction.
