Validation française d’une version brève de l’Échelle de satisfaction maritale

IntroductionFew measuring instruments of couple satisfaction maximizing the individual perception of the relationship exists in French. Settings such as Liaison psychiatry of a general hospital could benefit from a questionnaire adapting to a variety of clinical profiles.ObjectiveThis article proposes a French revision and validation of the Marital Satisfaction Scale (MSS; Roach, Frazier, and Bowden, 1981), a 48-item self-reported questionnaire designed to evaluate personal satisfaction towards one's couple relationship.MethodA sample of 349 community-dwelling individuals aged 20–85 answered the MSS, the Dyadic Adjustment Scale (DAS; Spanier, 1976), and a series of inquiries related to sociodemographics. As an initial Exploratory Factor Analysis (EFA) did not validate the unidimensional structure postulated by the original authors, the item number was reduced to 14.ResultsThis brief version of the scale (MSS-14) was subsequently validated with an internal replication analysis, a strong criterion-related validity with the DAS (r_s = 0.73, P < 0.001), an excellent internal consistency (α = 0.961, IC à 95% [0.955, 0.967]), a strong test-retest reliability (r_s = 0.90, CI à 95% [0.85, 0.93], P < 0.001, Z = − 0.033, P = 0.973), and strong item-to-total correlations (> 0.69). The MSS-14 could differentiate individuals with and without marital distress (AUC = 0.97), while no sociodemographic variable seemed to have a significant influence on couple satisfaction.ConclusionThe MSS-14 appears to be a reliable instrument to assess the personal satisfaction towards a couple relationship in community-dwelling adults.     

No blank slates: Pre-existing schemas about pharmaceuticals predict memory for side effects

Objectives: Attribution of symptoms as medication side effects is informed by pre-existing beliefs about medicines and perceptions of personal sensitivity to their effects (pharmaceutical schemas). We tested whether (1) pharmaceutical schemas were associated with memory (recall/recognition) for side effect information (2) memory explained the attribution of a common unrelated symptom as a side effect.

Design: In this analogue study participants saw the patient leaflet of a fictitious asthma drug listing eight side effects.

Main outcome measures: We measured recall and recognition memory for side effects and used a vignette to test whether participants attributed an unlisted common symptom (headache) as a side effect.

Results: Participants who perceived pharmaceuticals as more harmful in general recalled fewer side effects correctly (r_{Correct Recall} = ?.273), were less able to differentiate between listed and unlisted side effects (r_{Recognition Sensitivity} = ?.256) and were more likely to attribute the unlisted headache symptom as a side effect (r_{side effect attribution} = .381, ps < .01). The effect of harm beliefs on side effect attribution was partially mediated by correct recall of side effects.

Conclusion: Pharmaceutical schemas are associated with memory for side effect information. Memory may explain part of the association between pharmaceutical schemas and the attribution of unrelated symptoms as side effects.     

Measuring adult indirect aggression: The development and psychometric assessment of the indirect aggression scales

This paper describes the development of a psychometric measure of indirect aggression for use in an adult population. Items were generated from a series of qualitative interviews. Two versions of the scale were developed; the Indirect Aggression Scale Aggressor version (IAS‐A) and Target version (IAS‐T). Both versions of the scale were administered to separate samples (n_A=294; n_T=294). Scales were analysed using item analysis of internal consistency, as well as exploratory factor analysis. Both versions were found to have the same consistent three sub‐scales: social exclusion, use of malicious humour, and guilt induction. Preliminary psychometric evaluation suggests that the scales are both sufficiently reliable (with Cronbach's alphas ranging from .81 to .89) and valid. There were no gender differences in either using or being the victim of indirect aggression, and the behaviour was significantly negatively correlated with age. Future validation and potential usage of the measures are discussed. Aggress. Behav. 31:1–14, 2005. © 2005 Wiley‐Liss, Inc.     

The Dimensionality of Right-Wing Authoritarianism: Lessons from the Dilemma between Theory and Measurement

The RWA Scale ( Altemeyer, 1981 , 1988 , 1996 ) is commonly regarded as the best measure of right-wing authoritarianism. The one-dimensional instrument assesses the covariation of three attitudinal clusters: authoritarian submission, authoritarian aggression, and conventionalism. The incongruence between the implicit conceptual dimensionality on the one hand and methodological operationalization on the other makes room for discussion about whether it would be advantageous to measure the 3 facets of RWA separately. I rely on three arguments: (1) confirmatory factor analyses showing that three-dimensional scales fit the data better than the conventional one-dimensional practice; (2) the dimensions showing a considerable interdimension discrepancy in their capability to explain validation criteria; and (3) the dimensions showing an intradimensional discrepancy which is dependent upon the research question. The argumentation is illustrated by empirical evidence from several Web-based studies among German Internet users.     

中国人人格七因素量表(QZPS-SF)的信度与效度

本研究的目的是依据中国人人格量表（QZPS）编制一份能够迅速测查人格七个维度的短式七因素量表（QZPS—SF）。根据6000余名被试对QZPS的215个项目的评定分数,通过因素分析确定了七个因素、与QZPS的七个因素对应构成了QZPS—SF。通过被试的自我评定以及他人评定和特殊群体被试（精神分裂症病人、吸毒者以及罪犯）的人格特点比较,显示了QZPS—SF有着良好的信度和效度。文中还对QZPS—SF的应用范围以及注意事项进行了讨论。     

反应风格的测量与统计控制

反应风格是共同方法偏差的主要来源之一。本文首先讨论反应风格的定义和类型,梳理其危害,认为反应风格能使测验分数出现偏差,影响测验信效度分析和变量关系分析,有必要控制其危害。然后介绍了常用的反应风格测量方法,包括计数法和模型法两大类,对测量方法的选择给出了建议,在此基础上,就如何结合反应风格的测量方法与残差回归法、偏相关法来控制反应风格危害给出建议。     

Likert量表分析中不同IRT模型的有效性

5级Likert量表可直接分析,也可以转化为3级评分,或转化为2级评分。前二者可以采用等级IRT模型,后者可以采用2级IRT模型。研究表明2级IRT模型中的2参数模型是最适合的模型。多级评分模型与数据拟合也很好,而且等级越多测量精度越大。     

Small wonders of the Indian market

Heavy competition in India in almost all product categories, due to diversification by large and medium companies and increased entry of multinationals, has restricted the growth of domestic companies. Previously, large companies enjoyed high profit margins by targeting premium priced products in the upper strata of Indian society. High levels of competition from equally reputed brands have not only decreased the companies' market share but also created price wars, reducing profit margins and limiting market growth. This has motivated companies to consider the lower classes and the rural segments, which they had previously ignored. By targeting these segments with products in small packs at lower price points, companies have experienced great success. At the same time, small packs also pose some challenges for the companies. This paper explains the importance of small packs for market expansion in various product categories within the Indian market, drawing on several examples to support the views of the authors.
