Package size and perceived quality: The intervening role of unit price perceptions

This research examines how package size can influence quality judgments for packaged goods, and also identifies a price-based mechanism for the observed size–quality relationship. Results from several studies show that a product in a smaller package is rated more favorably than the equivalent product in a larger package. Further, this effect is due to the smaller package being associated with a higher unit price (despite having a lower overall price), which suggests that unit price information is more diagnostic than overall price information when forming judgments of product quality. We also find a theoretically-derived reversal of this effect under conditions in which the greater diagnosticity of unit price is overwhelmed by its lower ease of use. Namely, when overall price is the only explicitly-provided price cue and consumers are too distracted to estimate unit price, a larger package is now rated as being better. Finally, two concluding studies examine the downstream consequences of changes in package size, building off our basic conceptualization to document effects on product choice as well as consumption experience.     

眼睛效应不稳定与感知规范：一个新视角

眼睛效应指人们面对眼睛或类似眼睛的图案时会发生行为改变的现象。但是, 眼睛效应的稳健性备受争议, 主要有4种观点：促使人们更亲社会、更遵守社会规范、降低反社会行为、无效果。结合规范错觉和创新扩散理论, 基于感知规范的视角, 当感知亲社会规范流行程度较高时, 眼睛效应既会“促进亲社会行为”或“促进人们遵守社会规范”, 也会“降低反社会行为”; 但当感知亲社会规范流行程度较低时, 眼睛效应对一些反社会行为“无效果”; 当规范错觉较大且无规范干预时, 眼睛效应同样对一些反社会行为无效果。因此, 将以上4种争议观点整合为“不同感知规范条件下的眼睛效应”, 揭示了眼睛效应不稳定的原因, 为未来实证研究和实践应用提供理论基础。     

Life experiences of people who stutter, and the perceived impact of stuttering on quality of life: personal accounts of South African individuals

The purpose of the study was to investigate the life experiences of a group of South African adults who stutter and the impact of stuttering on their quality of life. Participants were 16 adults with a mean age of 28.9 and ranging from 20 to 59 years. Methods involved individual interviews designed to explore the life domains of education; social life; employment; speech therapy; family and marital life; and identity, beliefs and emotional issues. Main findings of the study indicated that the majority of participants perceived their stuttering to have impacted on their academic performance at school, and relationships with teachers and classmates. Although their stuttering was not perceived to adversely influence their ability to establish friendships, people generally reacted negatively to their stuttering. Many felt that their stuttering did not have an adverse effect on their choice of occupation, ability to obtain work, and relationships with managers and co-workers, although it was perceived to influence their work performance and hamper their chances for promotion. Although the majority viewed their speech therapy experiences as being negative; more than half the sample believed that speech therapy had, nevertheless exerted a positive effect on their quality of life. Overall, stuttering did not appear to have influenced participants’ family and marital life. Most participants felt that stuttering had affected their self-esteem and self-image, and had evoked strong emotions within them. Findings are taken to suggest the need to incorporate subjective feelings about stuttering into the clinical practice of speech-language therapy; to provide information and coping strategies for teachers and employers; and for further research.

Educational objectives: After completing this activity, the reader will be able to: (1) describe and explain the perceived impact of stuttering on quality of life in terms of education; social life; employment; speech therapy; family and marital life; and identity, beliefs and emotional issues; (2) to interpret and utilize the subjective meanings that individuals attach to their stuttering to improve stuttering treatment, counseling and research.     

Level of service of pedestrian facilities: Modelling human comfort perception in the evaluation of pedestrian behaviour patterns

The paper presents a new methodology for evaluating the quality of operation of pedestrian facilities: the methodology is based on the individual level of comfort perceived by each pedestrian that moves in the area.At each time instant, each pedestrian perceives a comfort level which is a function of the space they feel currently available and of his required space. The required space depends on the subject’s walking direction as well as on physical and psychological factors. The available space depends on the current positions of pedestrians. The proposed methodology quantifies the current discomfort due to pedestrian interactions as a continuous function of the interpersonal distances.The proposed methodology has been applied to empirical data. The experimental data are presented, discussed and compared with widely accepted level of service assessment methods.     

State of the aRt personality research: A tutorial on network analysis of personality data in R

Network analysis represents a novel theoretical approach to personality. Network approaches motivate alternative ways of analyzing data, and suggest new ways of modeling and simulating personality processes. In the present paper, we provide an overview of network analysis strategies as they apply to personality data. We discuss different ways to construct networks from typical personality data, show how to compute and interpret important measures of centrality and clustering, and illustrate how one can simulate on networks to mimic personality processes. All analyses are illustrated using a data set on the commonly used HEXACO questionnaire using elementary R-code that readers may easily adapt to apply to their own data.     

Testing the conditional independence and monotonicity assumptions of item response theory

When item characteristic curves are nondecreasing functions of a latent variable, the conditional or local independence of item responses given the latent variable implies nonnegative conditional covariances between all monotone increasing functions of a set of item responses given any function of the remaining item responses. This general result provides a basis for testing the conditional independence assumption without first specifying a parametric form for the nondecreasing item characteristic curves. The proposed tests are simple, have known asymptotic null distributions, and possess certain optimal properties. In an example, the conditional independence hypothesis is rejected for all possible forms of monotone item characteristic curves.The author acknowledges Paul W. Holland for valuable conversations on the subject of this paper; Henry Braun and Fred Lord for comments at a presentation on this subject which led to improvements in the paper; Carl H. Haag for permission to use the data in §4; Bruce Kaplan for assistance with computing; and two referees for helpful suggestions. Requests for reprints should be sent to Paul R. Rosenbaum     

New evidence on the reliability and validity of the pediatric oncology quality of life scale

Abstract

The present paper replicates and extends previous studies on the psychometric properties of the Pediatric Oncology Quality of Life Scale (POQOLS). The research questions were focused on (a) internal consistency; (b) relation with demographics; and (c) ability to discriminate between patient groups. Data were gathered in a Dutch-speaking Belgian sample of 73 pediatric oncology patients, drawn from the population of a university hospital. The parents completed the POQOLS, a 21-item parent-report inventory for the assessment of physical restriction, emotional distress and discomfort from medical treatment in pediatric oncology patients. The results support the psychometric quality of the POQOLS. Three of the core aspects of quality of life are tapped using sufficiently short and internally consistent subscales. The instrument is free from relations with demographics and shows good discriminant ability to differentiate between patient groups according to time since diagnosis, treatment status and diagnosis.     

Assessing quality of care and observance of human rights in residential mental health facilities in Greece through the WHO QualityRights tool kit

In this paper, we present and reflect upon the process of evaluating two residential mental health facilities in Thessaloniki, Greece, through the WHO QualityRights tool kit. The QualityRights tool kit is a structured process for assessing quality of care and human rights in mental health and social care facilities, in accordance with the United Nations Convention on the Rights of Persons with Disabilities (CRPD), introduced by the World Health Organization in 2012. We have piloted the use of the Toolkit in two supported accommodation facilities, a hostel and a service supervising independent living in apartments, for individuals with long-term severe mental health problems in the region of Thessaloniki. In this paper, we present the methodology and process of evaluating the facilities, including the challenges posed to the evaluation process by restrictions due to the Covid-19 pandemic. We showcase the outcome of this evaluation through presenting a summary of the results and the ensuing recommendations for improvement. Finally, we reflect on the usefulness, appropriateness and relevance of the Toolkit for evaluating mental health care facilities in the particular context of contemporary Greece.     

Trichotillomania: impact on psychosocial functioning and quality of life

This study explored the impact of hair pulling on psychosocial functioning for patients diagnosed with trichotillomania (TTM; n = 28). TTM patients were compared to age and gender-matched groups of psychiatric patients without TTM (n = 28) and nonpsychiatric control volunteers (NC, n = 28) on measures of psychological distress, functioning/quality of life, and self-esteem. Results indicated that TTM patients reported more severe psychosocial impairments than did NC volunteers; however, these differences were mediated by differences in level of depression. Regression analyses indicated significant relationships between some measures of psychosocial functioning and severity of hair pulling, independent of level of depression. Finally, an interview of the impact of hair pulling on 6 domains of daily functioning (negative affect/negative self-evaluations, grooming, recreational activities, social interaction, work/housework productivity, and physical health) indicated common and wide-ranging impairments for both lifetime and current (i.e., past week) ratings. These results highlight the importance of promoting and improving resources for the clinical care of TTM patients, and provide some directions for clinicians to enhance assessment of interference caused by TTM.

A randomised controlled trial of the effects of implementation intentions on women's walking behaviour

The combination of low physical activity rates and increased cardiovascular deaths indicate the overwhelming need for behaviour change interventions that can effectively promote physical activity among sedentary women. This 11-week randomised controlled trial examined the effects of an implementation intentions intervention on sedentary women's walking behaviour. Seventy-five women (M age = 48.17) were randomly assigned to either a control group where they were required to self-monitor their daily pedometer-determined step count or to an experimental group where they were asked to form specific walking plans (i.e. implementation intentions) every 6 weeks and to self-monitor their daily pedometer-determined step count. Measures of exercise intentions, perceived behavioural control, scheduling and barrier self-efficacy were administered at baseline, week 6 and week 11. Analyses indicated higher step counts over the first 6 weeks for women in the experimental condition (p < 0.02). Furthermore, higher self-efficacy to schedule (p < 0.01) and overcome walking barriers (p < 0.03), as well as higher perceptions of behavioural control (p < 0.02) were found at week 11 for women in the experimental versus control condition. However, none of the control beliefs were found to mediate the effects of the intervention on the women's walking behaviour. Furthermore, the intervention did not have any effect on the strength of the goal intention–behaviour relationship. The findings suggest implementation intentions are an effective strategy for initiating leisure-time walking within sedentary women.     

The impact of the transition to high school on the self-system and perceived social context of poor urban youth

Examined the effects of the normative school transition to senior high school (n=330) on the self-system and perceived school and peer social contexts of poor, black (n=83), European American (n=115), Latino (n=105), and Asian American (n=27) youth in the public school systems of three Eastern urban cities. The only negative effect of the school transition on the self-system was a decline in grade point average (GPA). Concurrently, the school transition was perceived to be associated with changes in the school and peer contexts. Across the transition, students reported increased disengagement from school (i.e., increased social support and extracurricular involvement) and increased engagement with peers (i.e., decreased daily hassles and increased involvement). These changes in the school and peer microsystems, like the changes in the self-system, were also common across race/ethnicity and gender. In addition, transition-associated school changes, and in particular changes in daily academic demands/hassles and involvement in school activities, were associated with changes in the academic dimensions of the self-system (i.e., academic efficacy expectations and GPA). Results and implications for preventive intervention are discussed within a developmental mismatch framework. This research was supported in part by grants from the National Institute of Mental Health (MH43084) and the Carnegie Corporation (B4850) awarded to Edward Seidman, J. Lawrence Aber, LaRue Allen, and Christina Mitchell. We express our appreciation to the children and schools whose cooperation made this study possible.

The feasibility,reliability and validity of the EORTC QLQ-C30 in assessing the quality of life of patients with a symptomatic HIV infection or AIDS (CDC IV)

Abstract

The objective of this study was to evaluate the feasibility, reliability and validity of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (the QLQ-C30) in a longitudinal study of the quality of life (QoL) of patients with a symptomatic HIV infection or AIDS. The OLQ-C30 is a 30-item questionnaire composed of five functional subscales. 3 symptom subscales, an overall QoL subscale, and a number of additional single item symptom measures. The questionnaire was administered serially to a sample of 156 Dutch patients. The average time to complete the questionnaire was less than 11 minutes, with most patients requiring no assistance. With one exception (role functioning subscale), the data supported the hypothesized scale structure of the questionnaire. Eight of the 9 subscales met or approached the minimal criterion for reliability (Cronbach's alpha ≤ .70) at baseline and/or follow-up. The validity of the QLQ-C30 was supported by 3 findings: (1) the correlations observed among the subscales. while statistically significant, were of only a moderate magnitude, indicating that distinct components of QoL are being assessed; (2) a number of the subscales could discriminate clearly between patients differing in stage of disease and in Karnofsky Performance Status; and (3) significant changes in QLQ-C30 scores in the expected direction, were observed over time. These results lend support to the QLQ-C30 as a reasonably reliable and valid instrument for assessing the QoL of patients with HIV infection. Additional research is needed to improve the role functioning subscale. to evaluate the QLQ-C30's concurrent validity by comparing it with other available QoL instruments, and to examine more thoroughly its responsiveness to clinically important changes in patients' health status over the entire disease and treatment trajectory.     

The Impact of Criminal Record Stigma on Quality of Life: A Test of Theoretical Pathways

Across multiple stigmatized groups, research suggests that stigma may negatively impact individual wellbeing. This impact often occurs through a sequential pathway that includes perceiving societal stigma, a diminished and stereotyped self‐concept (i.e., internalized stigma), experiences of discrimination and rejection, and attempts to cope with stigma (e.g., secrecy or withdrawal). While prior research supports individual links within this pathway, no study has evaluated a model representing the relationships between all of these factors in relation to criminal record stigma. This study utilized cross‐sectional data from an online survey of 198 adults to test the pathways through which criminal record‐related stigma impacts individual quality of life. The results indicated that perceived stigma was a significant predictor of discrimination and rejection experiences, secrecy coping strategies, and decreased quality of life. There was also a significant indirect association between perceived stigma and quality of life through secrecy coping. Consistent with recent criminal record stigma research, internalized stigma was low among respondents. These findings point to the importance of reducing criminal record stigma and discrimination, so that individuals with criminal records have more opportunities to enhance their quality of life without having to withdraw from society or keep their record a secret.     

The role of job resources in the relation between perceived employability and turnover intention: A prospective two-sample study

We hypothesize that the relationship between perceived employability (PE) and turnover intention is stronger when job resources (job control, social support from the supervisor and colleagues) are low. Results from a prospective study one year apart were similar in samples of Finnish university (N = 1314) and hospital workers (N = 308). The interaction between PE and job control related significantly to turnover intention at Time 2 in both samples, and in the hospital sample also when controlling for turnover intention at Time 1: PE related positively to turnover intention when job control was low. Furthermore, PE at Time 1 was not significantly related and job resources at Time 1 were negatively related to turnover intention at Time 2. For social support from colleagues in particular, this relationship held when controlling for Time 1 turnover intention. Thus, PE does not present a risk of turnover intention, unless job control is low.     

婚姻质量对父母协同养育的影响：基于共同命运模型的跨层中介分析

共同命运模型(common fate model, CFM)是在家庭或二元层面研究中值得信赖的模型, 其更好地解释了亲密关系内在的相互依赖性。本研究基于共同命运模型探讨了家庭整体婚姻质量对父母协同养育程度的影响, 以及教养能力感在两者间的跨层中介作用。采用问卷法分层整群抽取上海市幼儿园中孩子(平均年龄5.14岁, 年龄范围4~7岁)的父亲与母亲参与调研, 分两个时间段(T1, T2; 间隔1年)收集数据, 最终得到650个家庭的父亲、母亲的婚姻满意度问卷(T1), 教养能力感问卷(T2)和协同养育感知问卷(T2)数据进行分析。结果发现: (1)基于共同命运模型, 家庭层面的婚姻质量正向预测家庭层面的支持性协同养育, 并负向预测家庭层面的破坏性协同养育; (2)家庭层面的婚姻质量正向预测父母各自的教养能力感; (3)父母各自的教养能力感正向预测家庭层面的支持性协同养育, 并负向预测家庭层面的破坏性协同养育; (4)父母个人层面的教养能力感在家庭层面的婚姻质量与家庭层面的支持性协同养育和破坏性协同养育起中介作用。总之, 本研究基于追踪数据运用共同命运模型, 并结合家庭层面(婚姻质量和协同养育)和个人层面(教养能力感)探讨了教养能力感在婚姻质量与父母协同养育间的跨层中介效应, 为营造良好的家庭环境提供一定的理论支持与指导意见, 并进一步促进了共同命运模型发展。     

A meta-analysis of the n-back task while driving and its effects on cognitive workload

This study investigates the effect of the n-back task on cognitive workload while driving. Results of 20 studies with over 800 participants in total show a moderate to high mean effect size. That means the n-back task varies cognitive load while driving in a substantial matter. Further analysis reveals several moderator variables: experiments conducted in a driving simulator showed larger effect sizes than on-road studies. This effect decreases with increasing driving simulator fidelity. Furthermore, the specific driving task assignment moderates the effect: lane change task scenarios result in higher effects than other situations. Regarding the different measurement methods of cognitive workload, subjective questionnaires seem to have very high sensitivity. In contrast, n-back performance measures, detection response task measures, and physiological measurements result in moderate effect sizes, and driving performance measures show reduced sensitivity. Regarding different implementations of the n-back task itself, surprisingly, no moderators are found. Overall, the findings highlight the suitability of the n-back task as a method of inducing cognitive load in transportation research. The moderator analysis gives an overview of different methodological designs and how these designs will affect effect sizes.
