The physician values in practice scale: Construction and initial validation

Measures of values typically appraise the construct globally, across life domains or relative to a broad life domain such as work. We conducted two studies to construct and initially validate an occupation- and context-specific values measure. Study 1, based on a sample of 192 medical students, describes the initial construction and item analysis of the physician values in practice scale (PVIPS), which produced a 15-factor model. Study 2 reports on a further analysis and refinement of the instrument with a national sample of 644 medical students. Results supported the basic psychometric properties of the PVIPS items. Exploratory factor analysis in Study 2 extracted six factors consistent with a theoretical model of values (Dawis, 1991) and accounting for 61% of the variance: Prestige, Service, Autonomy, Lifestyle, Management, and Scholarly Pursuits. The PVIPS shows promise as a values measure for medical students and physicians encountering career specialty and medical practice style decisions. Interested researchers may construct similar scales for other occupations to promote contextualized appraisals of values.

A Short Measure of the Revised Reinforcement Sensitivity Theory – RSQ17

The need for a research and practical tool, such as a short, reliable, and valid personality assessment test, suggests researchers to create shortened versions of original instruments. Reinforcement sensitivity questionnaire (RSQ) was created in line with some basic premises of revised Reinforcement sensitivity theory, which proposes three motivational and emotional systems: Behavioral inhibition system (BIS), responsible for scanning environment for potential threats, Behavioral activation system (BAS), responsible for aproaching behavior, and the Fight/Flight/Freeze system (FFFS), responsible for behavior in the present threat. RSQ comprises five scales: BIS, BAS, Fight, Flight, and Freeze. The aim of this study was to develop a short version of RSQ, which would be beneficial to both research and practical purposes. Item response theory analyses were used for item selection. The study comprised two samples of participants, whereby Sample 1 (N = 837, 34.6% male, aged 18 – 82, M = 31.63, SD = 13.54) served as the derivation sample, while Sample 2 (818 participants, 43.6% male, 18?75 years, M = 29.65, SD = 12.52) served as validation sample. Factorial validity of the short RSQ was examined on both Sample 1 and Sample 2. Convergent and divergent validity of the short RSQ was examined using RST-PQ, Jackson-5, BIS/BAS scales, and Big Five Inventory. The results point to satisfactory internal consistency, factorial validity, and construct validity of the short RSQ, suggesting that it is an adequate measure for research settings or other contexts which require the use of short personality questionnaires.     

Cross-validation of the very short form of the Physical Self-Inventory (PSI-VS): invariance across genders, age groups, ethnicities and weight statuses

In a recent review of various physical self-concept instruments, Marsh and Cheng (in press) noted that the very short 12-item version of the French Physical Self-Inventory (PSI-VS) represents an important contribution to applied research but that further research was needed to investigate the robustness of its psychometric properties in new and diversified samples. The present study was designed to answer these questions based on a sample of 1103 normally achieving French adolescents. The results show that the PSI-VS measurement model is quite robust and fully invariant across subgroups of students formed according to gender, weight, age and ethnicity. The results also confirm the convergent validity and scale score reliability of the PSI-VS subscales.     

The Role of Short‐Term Mission Teams in the New Centers of Global Christianity

Drawing on ethnographic and interview data collected in El Salvador and South Africa over a four‐year period, this article uses a social constructionist approach to describe two types of interaction between short‐term mission teams and their hosts. First, hosts encounter the flow of teams as foreign social products. Once they internalize this new part of their social reality, hosts seek to recruit and control teams. They also mimic the practice of short‐term missions, sending their own teams to remote locations. Second, hosts interact directly with visitors, engaging in world‐building activities that create transnational religious ties. Short‐term missions thus make residents of the new centers of Christianity more mobile in Christianity's global civil society and increase the number of ties between Christians across borders. These findings have implications for the scholarly debate about how to conceptualize Global Christianity; they also broaden the scope of the emerging discourse on short‐term missions.     

Scaling the information processing demands of occupations

The purpose of this study was to provide additional validity evidence for a model of person–environment fit based on polychronicity, stimulus load, and information processing capacities. In this line of research the confluence of polychronicity and information processing (e.g., the ability of individuals to process stimuli from the environment along five dimensions of information load, interpersonal load, change load, time structure, and activity structure) is applied to the occupational environment. Using magnitude estimation scaling, college students in the United States and Portugal rated 42 occupations across five information processing demand characteristics. Results indicated that occupations could be differentiated by the information load conditions, thus producing a profile of information processing demand characteristics unique to each of the occupations tested. Additional findings provided evidence for the validity of the scaled occupational values; ratings differed reliably across Holland categories, were fairly consistent across the two cultural groups, and showed expected relationships with salary and educational level.     

Maternal depression and expressive communication in one-year-old infants

To separate effects of maternal depression on infant cognitive versus language development, 1-year-olds were assessed using the revised Bayley Scales of Infant and Toddler Development (BSID-III). Percentile scores on the Bayley Expressive Communication (EC) subscale were significantly negatively correlated with maternal self-report scores on the Beck Depression Inventory (BDI-II). However, mothers’ BDI-II scores did not correlate with infant percentile scores on the general cognitive (COG) or receptive communication (RC) subscales. Boys had significantly lower percentile scores than girls on the RC and EC scales, but did not differ on the Cog scale. Gender and maternal depression did not significantly interact on any of the scales. These findings suggest problems with expressive communication precede, and may at least partially account for, apparent deficits in general cognitive development.     

Development of a Short Form of the Test Anxiety Inventory (TAI)

The Test Anxiety Inventory (TAI) is widely used in research and practical settings and has particular application to the assessment and treatment of test anxiety in student populations. However, there are a number of instances in which a short version of the TAI would be more appropriate, especially when time constraints preclude the use of the full form. Similar short forms have been developed for other measures such as the State scale of the State-Trait Anxiety Inventory (STAI; T. M. Marteau & H. Bekker, 1992). The authors of the present study aimed to develop a short form of the TAI. The TAI was completed by 333 undergraduate psychology students. Item–remainder correlations were used to compare short forms with varying numbers of items. Internal consistency and concurrent and construct validity were assessed in hypothetical and actual examination conditions. A 5-item short form produced optimal reliability and validity, and a balance of items from the Worry and Emotionality subscales of the TAI. Further research is needed to replicate these results, but the 5-item short form of the TAI shows promise, particularly for contexts in which time demands preclude the use of longer versions.     

Anxiety: The cognitive perspective,by Michael W. Eysenck Hove,UK: Lawrence erlbaum; 1992; 195 pp.

Abstract

The purpose of the study was twofold: To investigate the structure of the test anxiety construct. and to compare the psychometric properties of rating scales versus questionnaire scales of test anxiety.

The intercorrelations among fourteen test anxiety measures, representing the one-, two-and four-dimensional models were examined as well as the correlations between those scales and eight measures of test-related perceptions.

The sample consisted of 172 undergraduate and graduate students of education. The results indicated that the underlying structure of the test anxiety construct consists of four primary factors. It was noted that the pattern of the relationships among the test anxiety measures remained intact when the broader context, which included also test-related perceptions, was studied. Based on the intra- and intercorrelations among the test anxiety and the test-related perceptions, a speculative causal model for explaining the effect of test anxiety on performance was suggested.

The findings regarding the format issue seemed to support the contention that rating scales are at least as valid measures of a simple single trait as questionnaire scales. However, it was stressed that further research is needed in order to find out whether or not rating scales are robust enough to be considered valid measures in situations that elicit social desirability distortion.     

The coupling of short sleep duration and high sleep need predicts riskier decision making

Abstract

Objective: To examine how risk-related decision making might be associated with habitual sleep variables, including sleep variability, sleep duration and perceived sleep need in young adults cross-sectionally and longitudinally.

Design: 166 participants completed a 7-day protocol with sleep and risk-related decision-making measures at baseline (T1) and 12 months later (T2).

Results: Habitual short sleep duration (averaging < 6?h nightly) was identified in 11.0% in our sample. After controlling for baseline demographic factors and risk-taking measures, self-reported sleep need at T1 interacted with habitual short sleep in predicting risk taking at follow-up (F_8,139=9.575, adjusted R²=.431, p<.001). T1 greater perceived sleep need predicted more risk taking among short sleepers, but decreased risk taking among normal sleepers at T2. Variable sleep timing was cross-sectionally correlated with making more Risky choices at baseline and fewer Safe choices after loss at follow up.

Conclusions: Young adults with variable sleep timing and those with short sleep duration coupled with high perceived sleep need were more likely to take risks. The moderating effects of perceived sleep need suggest that individual differences may alter the impact of sleep loss and hence should be measured and accounted for in future studies.
