Predictive validity of the medical specialty preference inventory

Medical schools can assist students by providing them with quality career counseling to help them choose a medical specialty. Many schools use interest inventories to help identify students’ specialty interests. This study examined the predictive validity of one such inventory, the Medical Specialty Preference Inventory (MSPI). In a longitudinal design, we used discriminant function analysis to examine how well students’ scores on the MSPI fit their chosen medical specialty one year later. The MSPI correctly predicted students’ future medical specialty choice 58.1% of the time. These results can help career advisors interpret MSPI scores, and identify students’ most likely medical specialty choice, as well as their second most likely choice.     

Construct validity of the medical specialty preference inventory: A critical analysis

The Medical Specialty Preference Inventory (MSPI; Zimny, G.H. (1979). Manual for the Medical Specialty Preference Inventory. St. Louis, MO: St. Louis University School of Medicine), a measure of medical students’ interests, was substantively and empirically examined to identify an underlying factor structure. A factor model for the original MSPI based on 38 factors in five general areas was evaluated on a national sample of 1014 medical students and yielded poor fit to the data. Exploratory factor analyses at the item level utilizing the full pool of MSPI items produced an 11 factor solution with 88 items. Sub-scales were identified within this model and an 11-18 higher-order model and an 18 sub-scale model also were proposed. The relative fits of the three models were evaluated by confirmatory factor analysis with the 18 sub-scale model shown to be superior. This model was cross-validated on a separate sample of 1016 medical students and fit the data well. All sub-scales exhibited adequate internal consistency across samples. These findings support the need for a revised MSPI based on 18 scales. Implications of these findings for MSPI scoring practices are discussed along with future directions.     

Career decision making: The limits of rationality and the abundance of non-conscious processes

The terms of work have changed, with multiple transitions now characterizing the arc of a typical career. This article examines an ongoing shift in the area of vocational decision making, as it moves from a place where “it’s all about the match” to one closer to “it’s all about adapting to change”. We review literatures on judgment and decision making, 2-system models of decisional thought, the neuroanatomy of decision making, and the role of non-conscious processes in decision making. Acknowledging the limits of rationality, and the abundance of non-conscious processes in decision making, obliges us to act in ways that mitigate the inherent difficulties to which those processes make us vulnerable. We conclude that both rational and intuitive processes seem dialectically intertwined in effective decision making, and we offer a trilateral model of career decision making that includes rational and intuitive mechanisms, both of which are funded and kept in check by occupational engagement.     

A Spanish translation of Mehrabian and Russell's emotionality scales for environmental consumer psychology

The development of a translation of Mehrabian and Russell's scales for the measurement of pleasure, arousal and dominance from the original English to a Spanish version for use in Venezuela is described. The translated scales were administered to two samples of middle‐class Venezuelan consumers (n = 127,n = 127) between the ages of 20 and 50, among whom males and females were represented approximately equally. Internal reliability (measured by Cronbach's alpha) and scale validity (measured by factor analysis) indicate that the translated scales are suitable for consumer and other social psychological research in Spanish.

Choice in transition: A comparison of melioration and the kinetic model

Transition-state choice behavior of pigeons was examined in two experiments designed to test predictions of melioration and the kinetic model. Both experiments began with an initial training condition during which subjects were maintained on concurrent variable-interval schedules. In Experiment 1, subjects were then exposed to concurrent variable-ratio schedules, whereas in Experiment 2, subjects were then exposed to concurrent extinction. Contrary to the predictions of melioration, but consistent with the kinetic model, acquisition of preference on concurrent variable-ratio schedules followed a negatively accelerated logistic trajectory, and preference remained stable in concurrent extinction. Predictions made by the kinetic model concerning rates of switching between alternatives were also supported.     

A comparison of types of support for lower-skill workers: Evidence for the importance of family supportive supervisors

The work–family literature to date does not offer a clear picture in terms of the relative importance of different types of supports for balancing work and family demands. Grounded in conservation or resources theory, we develop an integrative model relating multiple forms of social support, both formal (i.e., work–life benefit use) and informal (supervisor work–family support and family support) to work-interference-with-family and family-interference-with-work and task and contextual performance. We chose to focus our study on lower-skill workers because, despite being a relatively large segment of the workforce, these workers are relatively understudied in the work–family literature. Results revealed that supervisor support is a key form of support in this sample. Supervisor support had negative same domain (work-interference-with-family) and cross domain (family-interference-with-work) effects with work–family conflict, as well as positive relationships with task and contextual performance. Family support was negatively related to family-interference-with-work; whereas use of work–life benefits was not significantly related to either form of work–family conflict or any of the performance variables. The implications of our results for conservation of resources theory and practical implications to employers of lower-skill workers are discussed.     

Burnout and connectedness among Australian volunteers: A test of the Job Demands-Resources model

This study used the Job Demands-Resources (JD-R) model, developed in the context of occupational well-being in the paid workforce, to examine the antecedents of burnout and connectedness in the formal volunteer rural ambulance officer vocation (N = 487). Structural equation modeling using self-reports provide strong evidence for the central assumptions of the JD-R model. The findings confirm that burnout fully mediates the relationship between job demands and health problems (Hypothesis 1), and between job demands and determination to continue (Hypothesis 2). In addition, results show that connectedness fully mediates the relationship between job resources and determination to continue (Hypothesis 3). These findings have important practical implications because of the increasing problem of volunteer recruitment and retention.

Exploring the Relationship between Adolescent Activities and Choice of Graduate School Discipline: Implications for Creativity Development

The relationship between adolescent extra‐curricular activities and choice of graduate‐education field was examined among students from three fields of study, science (n = 12), art (n = 12), and education (n = 14), using qualitative and quantitative methods. Results of profile analysis indicated that the different majors participated in stereotypically varying activities when they were adolescents. Science majors generally participated in mathematics and science activities during adolescence. Art majors generally participated in theater and music activities, and education majors tended to have participated in social leadership and educational activities. Interviews with the participants supported these findings and provided a more comprehensive discussion of these tendencies. While in high school, the participants had many influences when determining a field of study. Using personal happiness as a guide, the participants chose activities and ultimately graduate‐level majors that reflected their interests. It was concluded that adolescent extra‐curricular activities are important in the development of interest in creatively talented individuals and may lead to graduate field selection.     

The job demand-control(-support) model and physical health outcomes: A review of the strain and buffer hypotheses

Abstract

This review of the Job Demand-Control (JDC) model and the expanded Job Demand-Control-Support (JDCS) model and employees' physical health, focuses on the two prevalent views on these models. According to their view on the models researchers study different hypotheses: (a) the (iso)strain hypothesis, stating that the highest level of ill health is expected when the job is characterized by high demand and low control (and low social sup port), ot (b) the buffer hypothesis, predicting that control (and social support) can buffer the potential negative effects of high demands on physical health. It is argued that these hypotheses reflect theoretical distinct models, and that the practical implications associated with these models differ.

The review of 51 studies on the JDC(S) model reveals that the “strain” hypothesis predominates in studies of all-cause mortality, cardiovascular disease (CVD) related and specific non-CVD related health outcomes. In contrast, the “buffer” hypothesis is most prevalent in research on self-reported (psycho)somatic complaints. For the strain hypothesis as well as the buffer hypothesis the results are equivocal. Working in a high (iso)strain job appears to be associated with an elevated risk for cardiovascular disease and negative pregnancy outcomes, and increased (psycho)somatic complaints. Conclusions on other physical outcomes seem premature, considering the limited number of studies. The buffer hypothesis is supported in the few studies on CVD endpoints and in some studies on (psycho)somatic complaints.

A comparison of the validity of the two hypotheses is problematic, because they are mostly applied to a different set of outcomes. Furthermore, the analyses employed in the testing of the two hypotheses are of a different nature (non-linear versus linear).

The main recommendation for future research is to examine the validity of the strain and the buffer hypothesis concurrently, and to further explore the nature of the relationships.     

Exploring the route choice decision-making process: A comparison of planned and observed routes obtained using person-based GPS

Trip decisions are complex and involve choosing the activity destination, mode and subsequently the route for travel. This paper presents detailed information on the planned and observed route choices for the home-to-work commute. Specifically, the study examines how people formulate their route plans and describe their attitudes and preferences for their selected routes. A geographic information system (GIS) records the planned route information with the route planning sequence. Observing route choice is a difficult procedure; however, through the use of the global positioning system (GPS), one can accurately record route choice. An automated activity–trip detection algorithm processes GPS data and displays results within an internet-based prompted recall diary. The diary is used to verify trip start and end times. This combination of GPS, GIS and diary responses provides great insight into the route choice decision-making process. Thirty-one individuals from Ontario, Canada participated in answering survey questions and the collection of person-based GPS data. Results indicate a preference to minimize travel time as stated by participants in deciding what route to travel. Participants also affirmed a desire to minimize the number of stop lights/signs, as well as, avoid congestion and maximize route directness. A comparison between planned and observed routes, reveals about one-fifth of participants deviated from their planned route. This study demonstrates the need for qualitative and quantitative survey methods for exploring planned and observed route choice.     

A comparison of acceptance- and control-based strategies for coping with food cravings: an analog study

The present study utilized an analog paradigm to investigate the effectiveness of two strategies for coping with food cravings, which was theorized to be critical to the maintenance of weight loss. Ninety-eight undergraduate students were given transparent boxes of chocolate Hershey's Kisses and instructed to keep the chocolates with them, but not to eat them, for 48 h. Before receiving the Kisses, participants were randomized to receive either (a) no intervention, (b) instruction in control-based coping strategies such as distraction and cognitive restructuring, or (c) instruction in acceptance-based strategies such as experiential acceptance and defusion techniques. Measures included the Power of Food Scale (PFS; a measure of psychological sensitivity to the food environment), self-report ratings of chocolate cravings and surreptitiously recorded chocolate consumption. Results suggested that the effect of the intervention depended on baseline PFS levels, such that acceptance-based strategies were associated with better outcomes (cravings, consumption) among those reporting the highest susceptibility to the presence of food, but greater cravings among those who scored lowest on the PFS. It was observed that craving self-report measures predicted chocolate consumption, and baseline PFS levels predicted both cravings and consumption. Results are discussed in terms of the implications for weight loss maintenance strategies.     

Choice for aperiodic versus periodic ratio schedules: A comparison of concurrent and concurrent-chain procedures

Choice between mixed-ratio schedules, consisting of equiprobable ratios of 1 and 99 responses per reinforcement, and fixed-ratio schedules of food reinforcement was assessed by two commonly used procedures: concurrent schedules and concurrent-chains schedules. Rats were trained under concurrent fixed-ratio mixed-ratio schedules, in which both ratio schedules were simultaneously available, and under a concurrent-chains schedule, in which access to one of the mutually exclusive ratio schedules comprising the terminal links was contingent on a single “choice” response. The distribution of responses between the two ratio schedules was taken as the choice proportion under the concurrent procedure, and the distribution of “choice” responses was taken as the choice proportion under the concurrent-chains procedure. Seven of eight rats displayed systematic choice; of those, each displayed nearly exclusive choice for fixed-ratio 35 to the mixed-ratio schedule under the concurrent procedure, but each displayed nearly exclusive choice for the mixed-ratio schedule to fixed-ratio 35 under the concurrent-chains procedure. Thus, preference for a fixed or a mixed schedule of reinforcement depended on the procedure used to assess preference.     

An analysis of Holland's interest types for women: A comparison of the Strong-Holland and the ACT vocational interest profile scales for women

The purpose of this paper was to examine the basic vocational interest dimensions of women. Two interest inventories designed to measure the six interest dimensions described by Holland (1966) were administered to 126 university freshman women. The correlations between corresponding scales of the two instruments was generally high and application of the spatial configuration analysis resulted in the expected circular ordering found in previous studies. The usefulness of the basic interest dimensions when counseling with women was discussed from a practical and a theoretical point of view.     

Measurement invariance of the Utrecht Work Engagement Scale for Students: A study across secondary school pupils and university students

School engagement is a multidimensional construct characterized by vigour, dedication, and absorption towards academic work that is related to school achievement. This study aimed to examine the measurement invariance of a school engagement measure – the Utrecht Work Engagement Scale-Students (UWES-S) – across secondary school pupils and university students. Two samples of secondary school pupils (n = 251) and university students (n = 229) were used. The results supported the original three-factor structure (vigour, dedication and absorption) of the UWES-S instead of a two- or a one-factor structure in both samples. Evidence for the metric and scalar invariance of the measure across secondary school pupils and university students was also found. The university sample had higher scores in vigour and absorption but not in dedication. These findings demonstrate that the UWES-S can be used for developmental studies where school engagement and its relation with other variables needs to be compared across distinct educational levels.     

The roles of the central executive and visuospatial storage in mental arithmetic: A comparison across strategies

Previous research has demonstrated that working memory plays an important role in arithmetic. Different arithmetical strategies rely on working memory to different extents—for example, verbal working memory has been found to be more important for procedural strategies, such as counting and decomposition, than for retrieval strategies. Surprisingly, given the close connection between spatial and mathematical skills, the role of visuospatial working memory has received less attention and is poorly understood. This study used a dual-task methodology to investigate the impact of a dynamic spatial n-back task (Experiment 1) and tasks loading the visuospatial sketchpad and central executive (Experiment 2) on adults' use of counting, decomposition, and direct retrieval strategies for addition. While Experiment 1 suggested that visuospatial working memory plays an important role in arithmetic, especially when counting, the results of Experiment 2 suggested this was primarily due to the domain-general executive demands of the n-back task. Taken together, these results suggest that maintaining visuospatial information in mind is required when adults solve addition arithmetic problems by any strategy but the role of domain-general executive resources is much greater than that of the visuospatial sketchpad.

Experiences and engagement with the design features and strategies of an internet-delivered treatment programme for generalised anxiety disorder: a service-based evaluation

Background: Outcome research has highlighted the efficacy of internet-based cognitive behavioural therapy (iCBT). Some process research has examined users experiences of iCBT. Understanding the user experience provides valuable feedback to developers of internet-delivered interventions.

Aim: The present study aimed to evaluate user's experiences and engagement with the design features of an internet-delivered treatment programme for anxiety.

Methods: Semi-structured interviews were conducted with 7 participant users of the Space from Anxiety programme. A thematic analysis framework was employed to analyse the data collected.

Results: Identified themes related to participants engagement and adherence with the programme material, participant's experience of personal development through interaction with the programme content and participants experience of the social features employed in the programme. Another theme investigated the various attributes or conditions necessary for internet-delivered therapy to be helpful to an individual.

Conclusion: Considering the experiences of users of online interventions provides insight into what works for whom both in terms of technological features and the various skills and strategies that may compose the treatment intervention. Knowing more about what design features and strategies/components of the intervention are attractive and keep users involved can only enhance the delivery of effective internet-delivered interventions for anxiety disorders.     

A multi-dimensional measure of worry: Development and preliminary validation of the anxious thoughts inventory

This paper reports the development of a dispositional self-report measure of multiple dimensions of generalised worry. Factor analyses demonstrated a replicable three factor structure indicating that this measure of worry comprises three basic dimensions: social worry, health worry, and meta-worry. The first two factors reflect different content dimensions whereas the meta-worry factor consists of both content and process dimensions of worry. Individual differences in subscale scores show moderate stability over time, and the subscales possess good psychometric properties. Significant correlations were found between worry subscales and personality dimensions of self-consciousness and EPI scores. The role of multi-dimensional measurement in the exploration of worry is discussed.
