The impact of advertisements featuring ultra‐thin or average‐size models on women with a history of eating disorders

Previous research demonstrates that exposure to ultra‐thin media models leads to increased body image concerns amongst women (Groesz, Levine, & Murnen, 2002 ). There is emerging evidence that attractive, average‐size models do not have this negative effect and can be effective in advertising (e.g. Halliwell & Dittmar, 2004 ). The present study investigates these factors amongst women with a history of eating disorders. Participants either viewed advertisements featuring ultra‐thin, average‐size or control images. Immediately after exposure, they reported their body‐focused anxiety and rated the effectiveness of the advertisements. Whereas exposure to ultra‐thin models did not lead to increased body‐focused anxiety, exposure to average‐size models produced a relief effect, whereby women reported lower levels of body‐focused anxiety. Advertisements featuring ultra‐thin and average‐size models were equally effective. The results suggest that average‐size, attractive models could be used effectively in advertising, which may help to relieve body image concerns amongst these women.

Unemployment, coping and psychological distress

This study addressed the role of coping sytle in anxiety and depression of unemployed people. Two-hundred thirty-three people checking in at unemployment services participated. They filled in Carver, Scheier and Weintraub's (1989) coping measure (COPE), the Hospital Anxiety and Depression scale (HAD), gave information as to age, duration of unemployment and their appraisal of their situation. Four secondary dimensions of COPE were used in data analyses. Multiple regression analyses were undertaken with anxiety/depression as dependent and the coping variables as independent variables, with background/appraisal variables entered first. Coping variables added to the prediction of anxiety and depression over and above background/appraisal variables. For women Focus on Emotion coping as well as Avoidance was related to higher anxiety/depression scores ( p <0.01), whereas Reappraisal was related to lower anxiety/depression ( p <0.05). For men only Avoidance was related to anxiety/depression ( p <0.01). More Avoidance co-occurred with higher levels of anxiety as well as depression. The results are discussed with respect to possible intervention.     

Coping with bereavement in relation to different feminine gender roles

The effect of gender role on coping with conjugal bereavement was studied in 44 Norwegian widows. A "traditional" and a "modern" feminine gender role were juxtaposed. Information was collected by two semi-structured interviews concerning coping with bereavement, and by a health inventory (UHI). The information was analysed qualitatively in relation to central elements in the coping process (appraisals, problems, coping strategies, self-evaluations of coping, future expectancies of coping, and relevance of external resources). The findings revealed considerable differences in coping between the two gender roles, favouring the modern feminine gender role.     

Enduring stress: A quantitative analysis on coping profiles and sport well-being in amateur endurance athletes

Endurance athletes experience physical and psychological stress during training and competition that can inhibit performance and promote negative health implications (i.e., lower well-being) without proper coping mechanisms (McCormick et al., 2018; Sakar & Fletcher, 2014). Additionally, these athletes that train at an amateur level have received limited attention regarding coping with stress and how it impacts well-being (McCormick et al., 2018). The purpose of this study was threefold: to (a) determine common coping profiles of trained amateur endurance athletes, (b) explore the relationship between sport well-being and these coping profiles, and (c) examine the potential roles that appraisals might play in the coping-well-being relationship. The results yielded five distinct coping profiles: Mixed Adaptive Copers (MAC), Mixed Maladaptive Copers (MMC), Engaged Copers (EC), Avoidant Copers (AC), and Social Copers (SC). Coping profiles differed across various variables including sport well-being, appraisals, and demographic factors. Overall, MAC and EC had higher levels of sport well-being. MAC viewed stressors as a challenge (i.e., opportunity) compared to EC and AC. These findings suggest the complex nature of coping in sport and that athletes should develop an assortment of coping strategies that provide different strategies for various stressful situations.     

School programs targeting stress management in children and adolescents: A meta-analysis

Introduction

This meta-analysis evaluates the effect of school programs targeting stress management or coping skills in school children.

Methods

Articles were selected through a systematic literature search. Only randomized controlled trials or quasi-experimental studies were included. The standardized mean differences (SMDs) between baseline and final measures were computed for experimental and control groups. Experimental groups were groups that either received an intervention of (a) relaxation training, (b) social problem solving, (c) social adjustment and emotional self-control, or (d) a combination of these interventions. If no baseline measurement was available, SMDs were calculated between final measures of the groups. The overall pooled effect size was calculated and the pooled effect sizes of improvement on stress, coping, (social) behavior, and self-efficacy by random effects meta-analysis. The dependence of the results on study characteristics (i.e. methodological quality and type of intervention) was evaluated using meta-regression analysis.

Results

Nineteen publications met the inclusion criteria of controlled trials for class programs, teaching coping skills or stress management. Overall effect size for the programs was − 1.51 [95% confidence interval (CI) − 2.29, − 0.73], indicating a positive effect. However, heterogeneity was significant (p < .001). Sensitivity analyses showed that study quality and type of intervention were sources of heterogeneity influencing the overall result (p values < .001). The heterogeneity in quality may be associated with methodological diversity and differences in outcome assessments, rather than variety in treatment effect. Effect was calculated per intervention type, and positive effects were found for stress symptoms with a pooled effect size of − 0.865 (95% CI: − 1.229, − 0.502) and for coping with a pooled effect size of − 3.493 (95% CI: − 6.711, − 0.275).

Conclusion

It is tentatively concluded that school programs targeting stress management or coping skills are effective in reducing stress symptoms and enhancing coping skills. Future research should use clear quality criteria and strive for less diversity in methodology and outcome assessment.     

Does coping predict CO2-induced panic in patients with panic disorder?

Patients with panic disorder (PD) show maladaptive coping but the role of coping in the pathogenesis of panic is unclear. This study examined general coping and panic-specific coping as predictors of fear responding to CO2 inhalation. Subjective and physiological responses including panic attacks were assessed in 45 patients with PD and 45 matched nonclinical controls. Measures of coping were the primary predictors used in the analyses. Consistent with other reports, patients with PD reported increased emotion-focused coping and there was an association between emotion-focused coping and subjective reactivity. However, only panic-specific coping predicted panic attacks in response to the CO2 challenge.     

The sensitivity of response rate to the rate of variable-interval reinforcement for pigeons and rats: a review

The relation between the rate of a response (B) and the rate of its reinforcement (R) is well known to be approximately hyperbolic: B = kR/(R + Ro), where k represents the maximum response rate, and Ro indicates the rate of reinforcers that will engender a response rate equal to half its maximum value. A review of data reported in 17 published papers revealed that, under variable-interval schedules of reinforcement, Ro was usually lower when pigeons were the subjects than when rats were the subjects. The value of k, in contrast, did not differ consistently between pigeons and rats. Some accounts interpret Ro as the rate of alternative, unscheduled reinforcers in the situation, expressed in units of the scheduled reinforcer. So interpreted, the difference in Ro implies that less alternative reinforcement (relative to the scheduled reinforcement) typically is available to pigeons in their operant conditioning chambers than it is to rats in theirs. Whether or not that interpretation of Ro is valid, the pigeon-rat difference in Ro ensures that for reinforcer rates above about 10 per hour, response rate will be noticeably less sensitive to changes in reinforcer rate (and presumably to changes in other incentive and motivational operations) with pigeons than with rats as subjects, at least with the experimental conditions typically employed.     

In-vivo rating of treatment acceptability by children: Effects of probability instruction on student's spelling performance under group contingency conditions

In prior studies, Shapiro and Goldberg (1986, 1990) failed to find a relationship between in-vivo ratings by children of treatment acceptability and treatment effectiveness. These studies involved the use of interdependent and dependent group contingencies designed to improve the spelling performance of sixth grade students. To investigate whether the failure to link treatment acceptability and effectiveness may have been due to the subjects' inability to understand the differences in treatment conditions, this study utilized a pre-intervention training package to enhance salient differences between two types of group contingencies. Results of this study showed that both group contingencies were successful at improving the spelling performance of students, particularly the poorer spellers. Prior to treatment, students preferred the interdependent condition, with the higher-achieving students expressing the strongest preference. After implementation of the training package, both conditions were now rated as equally acceptable. Pre- and post-test acceptability ratings of each condition tended to be significantly correlated but correlations between acceptability ratings and treatment effectiveness were negligible at all points in the study. Limitations of the present study and suggestions for further research are discussed.
