Psychometric properties of the Shared Decision-Making Questionnaire (SDM-Q-9) in oncology practicePropiedades psicométricas del Questionnaire Shared Decision-Making (SDM-Q-9) en oncología

Background/Objective: This study sought to assess the psychometric properties of the 9-item Shared Decision-Making Questionnaire (SDM-Q-9) in patients with resected, non-metastatic cancer and eligible for adjuvant chemotherapy. Method: A total of 568 patients were recruited from a multi-institutional, prospective, transversal study. Patients answered the SDM-Q-9 after visiting their medical oncologist who, in turn, completed the SDM-Q–Physician version. Reliability, factorial structures [exploratory factor analysis (EFA), confirmatory factor analysis (CFA)], and convergent validity of the SDM-Q-9 scores were explored. Results: SDM-Q-9 showed a clear factorial structure, compatible with a strong and replicable general factor and a secondary group factor, in patients with resected, non-metastatic cancer. Total sum scores derived from the general factor showed good reliability in terms of omega coefficient: .90. The association between patient and physician perception of SDM was weak and failed to reach statistical significance. Males and patients over 60 years of age displayed the greatest satisfaction with SDM. Conclusions: SDM-Q-9 can aid in evaluating SDM from the cancer patients’ perspective. SDM-Q-9 is helpful in studies examining patient perspectives of SDM and as an indicator of the degree of quality and satisfaction with health care and patient-physician relationship.     

The effect of self-affirmation in nonthreatening persuasion domains: timing affects the process

Most research on self-affirmation and persuasion has argued that self-affirmation buffers the self against the threat posed by a persuasive message; thus, it increases the likelihood that participants will respond to the message favorably. Little research, in contrast, has looked at the effects of self-affirmation on persuasive messages that are not threatening to the self. This research examines mechanisms that can operate under these conditions. Consistent with the idea that self-affirmation affects confidence, the article shows that self-affirmation can decrease information processing when induced prior to message reception (Experiment 1) and can increase the use of self-generated thoughts in response to a persuasive message when induced after message reception (Experiment 2). In addition, Experiment 3 manipulates the timing of self-affirmation to replicate both effects and Experiment 4 provides direct evidence for the impact of self-affirmation on confidence.     

Psychometric properties of the Conflict Tactics Scales (CTS-2) in a Spanish sample of partner-violent men

Intimate partner violence is a complex problem that requires the update of the available assessment tools. The aim of the study is to test the revised Conflict Tactics Scales (CTS-2) in partner-violent men. Its structure and other psychometric properties are analyzed in 173 convicted offenders from Brians-2 and Alhaurín de la Torre penitentiaries. Discriminant validity is also assessed by comparing offenders with 108 males from the general population. The internal consistency for the 39 items of perpetration is .88 (varying from .59 to .83 among the subscales). The validity data indicate that the scale is useful to discriminate between batterers and general population in physical and psychological violence, although there is an overlap between different types of violence, and it is difficult to compare self-reports with external criteria such court decisions. The results of confirmatory factorial analysis do not support the original five-factor structure. Using exploratory factorial analysis, four components with good internal consistency were identified: Physical (.86), Sexual (.75), and Psychological Violence (.82), and Negotiation (.83). Recommendations for use and a reference guide of rating scores in samples of offenders are suggested.     

Spanish adaptation of the Psychological Well-Being Scales (PWBS)

The aim of this paper is to adapt to Spanish the D. van Direndonck version of Carol Ryff's Psychological Well-Being Scales, and to analyse its consistency and factorial validity. All the scales exhibited good internal reliabilities, with Cronbach alpha's ranging from 0.83 (Self-acceptance) to 0.68 (Personal growth). However, confirmatory factor analyses didn't corroborate the six-factor model (Self-acceptance, Positive relations, Autonomy, Environmental mastery, Purpose in life, and Personal growth) with a second order factor called Psychological Well-Being . To improve the psychometric properties, a new reduced version was proposed that indeed will facilitate the application. The scales of the new version maintain and raise its internal consistency (Cronbach alpha's 0.84 to 0.70). Furthermore, the scales shown an excellent fit to the theoretical model proposed by D. van Dierendonck.     

Perception: A HyperCard stack for demonstrating visual perceptual phenomena

Perception is a HyperCard stack that allows users to explore visual illusions and other perceptual phenomena on the Apple Macintosh. The stack contains over 20 demonstrations of intersecting line illusions, size and shape illusions, subjective contours, color assimilation, and so forth. As a presentation tool for classroom or laboratory demonstrations, Perception offers three unique features for displaying visual phenomena: (1) the capability to “dissolve” the inducing elements of an illusion in order to show the objective state of affairs, (2) the ability to quickly reverse the inducing elements of an illusion and therefore the effects of the distortion, and (3) animation of the various components of an illusion to produce continuous distortions in-real time. These features are illustrated with use of the Orbison, Titchener, Hering, and Wundt illusions. Use of the stack reveals two interesting and unanticipated findings: (1) an apparent size distortion in the central square of the Orbison illusion as it moves back and forth across the background of concentric rings, and (2) perceptual aftereffects that arise when the inducing elements of the Titchener, Hering, or Wundt illusion is dissolved.     

Communication technology: Pros and cons of constant connection to work

We examined the relationship between employees' attitudes related to communication technology (CT) flexibility, communication technology (CT) use, work-to-life conflict and work satisfaction. Based on data obtained from 193 employees, CT flexibility predicted more CT use. Further, CT use was associated not only with increased work satisfaction, but also with higher levels of work-to-life conflict. Finally, work-to-life conflict negatively predicted work satisfaction. Our findings point toward various trade-offs associated with CT use.     

Materialism and the Bright and Dark Sides of the Financial Dream in Spain: The Positive Role of Money Attitudes—The Matthew Effect

Research suggests that materialism leads to the dark side of the financial dream. In this study, we treat love of money as a mediator and test a theoretical model's direct path (Materialism to Financial Satisfaction) and indirect path (Materialism to Love of Money to Financial Satisfaction) simultaneously using the whole sample and across several demographic variables based on 1,011 citizens in Spain. Results for the whole sample showed that the positive indirect effect suppressed the negative direct effect creating an overall small positive effect. Furthermore, we found a significant negative direct path for rural dwellers, the 30–44‐year‐old age group, and married people, but a positive indirect path for rural residents, the 45–59‐year‐old age group, married, males, and urban dwellers. Overall, those in the 30–44 age group, rural residents, and married people experienced the dark side of the financial dream, whereas old (over‐60 age group), unmarried, urban, and young people (18–29 age group) enjoyed the bright side of their financial optimism. People's money attitudes and demographic variables play a positive role in our understanding of materialism and financial satisfaction, i.e. the Matthew Effect. Our novel, counterintuitive, and original theoretical, empirical, and practical contributions foster theory development and testing and improved practice.
