The SF-36 Among Cambodian and Vietnamese Refugees: An Examination of Psychometric Properties

Among traumatized Cambodian (N=90) and Vietnamese (N=94) refugees attending a psychiatric clinic, the study examined the validity and psychometric properties of the Short Form-36 Health Survey (SF-36), a measure of self-perceived mental and physical health. In both patient samples, all eight SF-36 scales displayed excellent internal consistency (item-scale correlations and Cronbach's α). But, similar to other studies of Asian samples, (a) the Vitality (VT) scale did not separate from the Mental Health (MH) and General Health (GH) scales, as evidenced by item-scale and interscale correlations, and (b) the VT scale loaded as strongly (Vietnamese sample) or more strongly (Cambodian sample) than the MH scale on the so-called Mental Factor in a two-factor solution of the eight scales (with the GH scale also loading heavily on the same factor).     

Integrating the most unintuitive empirical observations of 2007 in the domain of personality and social psychology into a unified framework

Two obstacles impede the development of productive theories in personality, social, and organizational psychology. First, the distinct frameworks are seldom integrated; the various theories sometimes yield incompatible implications. Second, because many findings in these fields seem intuitive, these observations do not augment the validity of these theories. To override these issues, this paper integrates the 70 most unintuitive findings of 2007 into a unified framework, derived from personality systems interaction theory. Specifically, 10 participants extracted the most unintuitive observations from 17 scholarly journals. These findings were reconciled within a single framework that generates 41 testable propositions. The framework assumes that an associative self system, underpinned by a vast network of schemas, governs behavior as well as enhances intuition, engagement, creativity, and cooperation. When individuals experience a threat, this system is inhibited, unless the requisite defense mechanisms to accommodate potential hazards have been developed. Furthermore, individuals attempt to distance themselves from unassailable threats, which activate an analytical system that formulates plans that could accommodate future contingencies. These plans are retained in memory or executed if individuals have acquired sufficient confidence.     

A mechanism for reducing delay discounting by altering temporal attention

Rewards that are not immediately available are discounted compared to rewards that are immediately available. The more a person discounts a delayed reward, the more likely that person is to have a range of behavioral problems, including clinical disorders. This latter observation has motivated the search for interventions that reduce discounting. One surprisingly simple method to reduce discounting is an "explicit-zero" reframing that states default or null outcomes. Reframing a classical discounting choice as "something now but nothing later" versus "nothing now but more later" decreases discount rates. However, it is not clear how this "explicit-zero" framing intervention works. The present studies delineate and test two possible mechanisms to explain the phenomenon. One mechanism proposes that the explicit-zero framing creates the impression of an improving sequence, thereby enhancing the present value of the delayed reward. A second possible mechanism posits an increase in attention allocation to temporally distant reward representations. In four experiments, we distinguish between these two hypothesized mechanisms and conclude that the temporal attention hypothesis is superior for explaining our results. We propose a model of temporal attention whereby framing affects intertemporal preferences by modifying present bias.     

Longitudinal Effects of Religious Media on Opposition to Same-Sex Marriage

Religion and anti-gay prejudice in the United States are closely connected. Yet we still know little about the specific mechanisms through which religious subcultures may shape adherents’ attitudes toward gays and lesbians. This study considers religious media consumption as a unique mechanism through which religious Americans are socialized and embedded within an anti-gay religious subculture. Drawing on panel data from the nationally-representative Portraits of American Life Study, and focusing on opposition to same-sex marriage as a measure of anti-gay prejudice, analyses show that more frequent consumption of religious radio and TV (but not internet) is associated with higher levels of opposition to same-sex marriage over time. These effects remain significant with different model specifications as well as controls for previous attitudes toward same-sex marriage, general media use, sociodemographic and religious characteristics, and intimate contact with gays and lesbians. We propose that consuming religious media over time may influence Americans’ views toward LGBT issues directly through explicit messages about homosexuality and indirectly by embedding Americans within a broader religious subculture (largely, conservative Protestantism) that opposes homosexuality.     

A Realistic Argument for Scientific Realism: How to be a Realist Without Really Knowing It

Philosophia - In this paper I provide a novel argument for scientific realism (SR). In contrast to most recent defenses of SR, my defense of SR does not rely on the no-miracles argument (NMA)....     

Word length and lexical activation: longer is better

Many models of spoken word recognition posit the existence of lexical and sublexical representations, with excitatory and inhibitory mechanisms used to affect the activation levels of such representations. Bottom-up evidence provides excitatory input, and inhibition from phonetically similar representations leads to lexical competition. In such a system, long words should produce stronger lexical activation than short words, for 2 reasons: Long words provide more bottom-up evidence than short words, and short words are subject to greater inhibition due to the existence of more similar words. Four experiments provide evidence for this view. In addition, reaction-time-based partitioning of the data shows that long words generate greater activation that is available both earlier and for a longer time than is the case for short words. As a result, lexical influences on phoneme identification are extremely robust for long words but are quite fragile and condition-dependent for short words. Models of word recognition must consider words of all lengths to capture the true dynamics of lexical activation.     

Modelling decisions to undergo genetic testing for susceptibility to common health conditions: An ancillary study of the Multiplex Initiative

New genetic tests reveal risks for multiple conditions simultaneously, although little is understood about the psychological factors that affect testing uptake. We assessed a conceptual model called the multiplex genetic testing model (MGTM) using structural equation modelling. The MGTM delineates worry, perceived severity, perceived risk, response efficacy and attitudes towards testing as predictors of intentions and behaviour. Participants were 270 healthy insured adults aged 25–40 from the Multiplex Initiative conducted within a health care system in Detroit, MI, USA. Participants were offered a genetic test that assessed risk for eight common health conditions. Confirmatory factor analysis revealed that worry, perceived risk and severity clustered into two disease domains: cancer or metabolic conditions. Only perceived severity of metabolic conditions was correlated with general response efficacy (β?=?0.13, p<0.05), which predicted general attitudes towards testing (β?=?0.24, p<0.01). Consistent with our hypothesised model, attitudes towards testing were the strongest predictors of intentions to undergo testing (β?=?0.49, p<0.01), which in turn predicted testing uptake (OR 17.7, β?=?0.97, p<0.01). The MGTM explained a striking 48% of the variance in intentions and 94% of the variation in uptake. These findings support use of the MGTM to explain psychological predictors of testing for multiple health conditions.     

Implications of Healthcare Payment Reform for Clinical Psychologists in Medical Settings

Health reform, post the passing of the Patient Protection and Affordable Care Act, has highlighted the need to better address critical issues such as primary care, behavioral health, and payment reform. Much of this need is subsequent to robust data showing the seemingly uncontrollable growth of healthcare costs, and the exacerbation of these costs for patients with comorbid behavioral health and medical conditions. There is increasing recognition that incorporating behavioral health in primary care leads to improved outcomes and better care. To address these problems, primary care will play critical roles across the healthcare system, especially in the delivery of behavioral health services. Psychologists are uniquely positioned to take advantage of this propitious moment and can help facilitate the integration of behavioral and primary care by developing competencies in integrated care, training a capable workforce, and advocating for integrated care as the status quo.
