A Test and Extension of the Demand/Control/Social Support Model: Prediction of Wellness/Health Outcomes in Greek Teachers

The present study investigated the relationship between job characteristics, coping strategies and job satisfaction, burnout and somatic complaints in 215 Greek secondary school teachers in the urban area of Thessaloniki, as part of the EUROTEACH project (11 countries, 2164 teachers). The study aimed at testing the hypotheses of the Demand-Control-Social support model (Karasek, <citeref rid="bib20">1979</citeref>); and examining whether additional job characteristics (working hours, environmental risks, meaningfulness and physical exertion) as well as the inclusion of coping strategies could improve the model. Instruments included the Leiden Quality of Work Questionnaire for Teachers; the SCL-90 somatisation scale; the Maslach Burnout Inventory; and the CISS. Results indicated that all three components of the original model are associated with the outcomes with some associations being nonlinear. However, the moderating effects of control and social support are not supported by the data. Regarding coping, results indicated that coping variables can explain variance in most of the outcomes of the study, in addition to all job characteristics. Regarding the additional job characteristics, meaningfulness of work is the most important predictor. In order to understand these findings better, the Greek data were compared to that of the EUROTEACH group. This comparison revealed that the Greek teachers differ from their European counterparts in most study variables. The direction is mainly to the positive side, with the exception of the experience of less control on the job. The implications of these findings concerning model-based studies on teachers are discussed.     

Development of the Significant Other Survey: An Interview for Family Members of Substance Users

The Significant Other Survey (SOS) is a semi-structured interview designed to measure the multidimensional problems experienced by family members with a substance abusing loved one. This article describes the development of the SOS and its psychometric properties based on data obtained from significant others of 110 substance abusing adults. Interrater and test-retest reliability estimates were within acceptable ranges, adequate internal consistency was demonstrated for six of seven problem domains, and the problem domains were low to moderately correlated with each other. Issues related to future instrument development and the utility of the SOS for both family practitioners and researchers are described.     

An Experimental Analysis of Mathematics Instructional Components: Examining the Effects of Student-Selected Versus Empirically-Selected Interventions

Within the context of an experimental analysis, the current study examined the effects of student- and empirically-selected interventions on the mathematics computational fluency of three elementary-aged students. For all of the participants, the empirically-selected intervention resulted in higher levels of computational fluency then the student-selected intervention. These results suggest that empirically-selected interventions may enhance the mathematics computational fluency of students experiencing mathematics problems. However, individual responsiveness to empirically-selected interventions suggests the importance of conducting brief experimental analyses to determine the most efficacious intervention. The implication of these results for intervention selection and incorporating choice-making opportunities into academic interventions are discussed.     

Through the Lenses of Gender, Race, and Class: Students’ Perceptions of Childless/Childfree Individuals and Couples

Earlier research has documented negative perceptions of childless couples, particularly the voluntarily childfree, among college students. In this project we used hypothetical vignettes to assess variations in students’ (N?=?478) perceptions of childless couples related to the couple’s race, occupations of husband and wife, and assumed reasons for childlessness. Perceptions were strongly influenced by occupational status and gender, but we found few race differences. Neither infertility nor chosen childlessness was rated negatively, but couples were rated more positively if they were perceived as temporarily rather than permanently childless. Our findings suggest that delayed parenthood is regarded as normative and that students have few negative biases regarding infertility or chosen childlessness. Perceptions were strongly conditioned by economic and employment considerations, which reflect current concerns about balancing work and family trajectories.     

Patterns of Posttraumatic Stress Symptoms Among United States Air Force Combat Search and Rescue Personnel

U.S. Air Force (USAF) combat search and rescue (CSAR) aircrew and special duty rescue personnel are specially trained airmen with high levels of direct exposure to combat-related medical trauma. The purpose of this study was to explore the prevalence rate of CSAR military personnel meeting the Diagnostic and Statistical Manual of Mental Disorders (fifth edition; DSM–5) posttraumatic stress disorder (PTSD) symptom criteria. USAF CSAR aircrew (n = 128) and rescue personnel (n = 300) across multiple units participated in the study by completing a demographics survey and the PTSD checklist based on DSM–5. Fourteen participants endorsed a pattern of symptoms of moderate to extreme level of severity meeting PTSD diagnostic criteria. Recommendations are provided for line and medical leadership to optimize health and performance among CSAR personnel.     

EFFECTS OF REINFORCER QUALITY ON BEHAVIORAL MOMENTUM: COORDINATED APPLIED AND BASIC RESEARCH

The high-probability (high-p) instructional sequence has been an effective treatment for noncompliance. However, treatment failures have also been reported. We hypothesized that the efficacy of the high-p treatment may be improved by using higher quality reinforcers for compliance to high-p instructions. The resistance of compliance to change was tested by varying reinforcer quality in two applied studies and a basic laboratory experiment. Experiment 1 tested the hypothesis that an increase in reinforcer quality for high-p compliance will increase the effectiveness of the high-p treatment when it fails to increase compliance. Experiment 2 assessed the effects of reinforcer quality on resistance of compliance to change by presenting successive low-p requests following the high-p treatment. A basic laboratory study (Experiment 3) was conducted to further isolate the relation between reinforcer quality and behavioral momentum. Two different liquid reinforcers (sucrose and citric acid solutions) were presented in a two-component multiple variable-interval variable-interval schedule followed by a single extinction test session. Results of all three experiments showed a generally consistent relationship between reinforcer quality and behavioral momentum.     

Psychosocial factors in heart surgery: presurgical vulnerability and postsurgical recovery

OBJECTIVE: Distress and low perceived social support were examined as indicators of psychosocial vulnerability in patients about to undergo heart surgery. Design: A total of 550 study patients underwent heart surgeries, including bypass grafting and valve procedures. Psychosocial interviews were conducted about five days before surgery, and biomedical data were obtained from hospital records. MAIN OUTCOME MEASURES: Sociodemographic, personality, religious, and biomedical factors were evaluated as predictors of psychosocial vulnerability, and all five sets of variables were evaluated as contributors to hospital length of stay (LOS). RESULTS: Patients scoring higher on one or more indicator of presurgical psychosocial vulnerability were younger, more likely to be female, less likely to be married, less well educated, lower in dispositional optimism, higher in trait anger, and lower in religiousness. Older age, depression, low support, and low trait anger each showed an independent, prospective association with greater LOS, and several other predictors had prospective relationships with LOS that were statistically mediated by depression or perceived support. CONCLUSION: Evidence that multiple psychosocial factors may influence adaptation to heart surgery has implications for understanding and ameliorating presurgical distress and for improving postsurgical recovery.     

Sexual Prejudice Among Heterosexual College Men as a Predictor of Condom Attitudes

Heterosexual male college students (N?=?100) (average age?=?19.7; 43% European American; 39% Christian) from the southwestern U.S. completed surveys in order to test a model predicting condom attitudes from religiosity, gender role attitudes, sexual prejudice, and the belief that “AIDS is a gay disease.” In the final model, those who reported more religiosity, more traditional gender role attitudes, and greater anxiety about interacting with gay men also reported feeling their core values and beliefs were threatened by gay men. In turn, men who felt strongly threatened in this way more strongly endorsed the belief that “AIDS is a gay disease,” and stronger endorsement of this belief was associated with more negative attitudes about condoms and condom use.     

The object of my protection: Shielding fundamental motives from the implicit motivational influence of others

Goal shielding theory suggests that one's focal pursuits automatically inhibit the activation of interfering goals (Shah, Friedman, & Kruglanski, 2002); however, it is not entirely clear how individuals come to identify what constitutes “interfering”. Three studies examine how this identification process may be guided by fundamental social motives that individuals possess, particularly in social situations wherein goals are primed through mere exposure to others' goal-directed behavior (“goal contagion”, Aarts, Gollwitzer, & Hassin, 2004). Participants' fundamental motives for positive self-regard (Study 1), autonomy (Study 2), and distinctiveness (Study 3) were either manipulated or measured and participants read scenarios that manipulated the goal-directed behavior of a target other. Results indicated that participants inhibited the activation of goals being primed by others when the implicit influence interfered with their fundamental motives in some way. These findings suggest that fundamental motives can guide whether individuals will catch goals from others or shield themselves from such influences.
