Innate Secretory Immunity in Response to Laboratory Stressors That Evoke Distinct Patterns of Cardiac Autonomic Activity
OBJECTIVE: Most infections begin at mucosal surfaces. These surfaces are covered by the secretory proteins of the exocrine glands (eg, the salivary, respiratory, and gastrointestinal glands), which provide a first line of innate defense. The release of these secretory proteins is under neuroendocrine control and thus, in theory, sensitive to modulation by psychosocial stress. This was empirically tested by measuring the salivary secretion of cyst…
Significant Effects Due to Rephrasing the Maslach Burnout Inventory's Personal Accomplishment Items
Subjects, 292 Dutch psychology students answering negatively phrased Personal Accomplishment items, reported a more personally competent feeling than subjects answering positively phrased personal accomplishment items. The way of phrasing personal accomplishment items significantly affects the answers given
Salivary MUC5B-Mediated Adherence (Ex Vivo) of Helicobacter pylori During Acute Stress
OBJECTIVE: Biochemical host defenses at mucosal sites, such as the oral cavity, play a key role in the regulation of microbial ecology and the prevention of infectious disease. These biochemical factors have distinct features, some of which benefit the host and some that benefit bacteria. We investigated the effects of acute stress on the salivary levels of the carbohydrate structure sulfo-Lewis (sulfo-Le), which is linked to the mucosal glycopro…
Factorial validity of the Maslach burnout inventory—Dutch version (MBI-NL) among dentists
Burnout is considered to be a long-term reaction to occupational stress. It is characterized by emotional exhaustion, depersonalization, and diminished personal accomplishment. The most widely used instrument to measure burnout is the Maslach Burnout Inventory (MBI), developed by Maslach and Jackson (1986). From this instrument, Schaufeli and van Dierendonck (1995a) developed a somewhat modified Dutch version: the MBI-NL. Burnout among dentists h…

Psychological Stress as a Determinant of Protein Levels and Salivary-Induced Aggregation of Streptococcus gordonii in Human Whole Saliva
Several pathologies of the oral cavity have been associated with stress, so we investigated salivary-induced aggregation during psychological stress. In addition, salivary total protein, alpha-amylase, and secretory immunoglobulin A (s-IgA) were assessed. In this longitudinal study, 28 dental students provided unstimulated whole saliva during 10 minutes before an academic examination and subsequently 2 weeks and 6 weeks later in a nonstress situa…
Robustness of the Photo Anxiety Questionnaire: Changing the Sequence of Stimuli and Photographs
In a split-ballot experiment (N=458) we tested, first, to what extent the logical presentation of the Photo Anxiety Questionnaire forces respondents into the usual response pattern, that is, a higher reported anxiety on items mentioning a time closer to dental treatment. Secondly, we tested whether subjects use the nonverbal response scale or merely use the position of the photographs on the scale when answering the questions. The original questi…
The Retrospective Pretest and the Role of Pretest Information in Evaluative Studies
To test the effect of training programs, subjects are often given self-report questionnaires. When such self-report instruments are used, response-shift bias is a possible confounder of results. According to the response-shift theory, pretest information given to subjects might reduce or diminish response-shift bias. In this experiment pretest information was given prior to a course in leadership. Contrary to expectation, the subjects' ratings we…
Anxiety and Blood Pressure Prior to Dental Treatment
In the present study dental anxiety and blood pressure were assessed immediately prior to a dental appointment to assess the relationship between self-reported dental anxiety and blood pressure. Blood pressure was assessed by two independent methods, and the interchangeability of the blood-pressure measurement methods was also assessed. No relationship was demonstrated among scores on three dental anxiety questionnaires and blood-pressure values.…
Response-Style Effects, Response-Shift Bias, and a Bogus-Pipeline: A Replication
In an earlier study by Sprangers and Hoogstraten, a bogus-pipeline induction did remove response-style effects in the self-reported pretest. Response-shift bias, defined as a significant mean difference between conventional pre- and retrospective preratings, was consequently eliminated. It was concluded that response-style effects in the pretesting are a likely cause of response-shift bias. The present experiment was designed to examine whether t…
Response-Style Effects, Response-Shift Bias and a Bogus-Pipeline
The influence of response-style effects on subjects' self-ratings was assessed, utilizing a bogus-pipeline technique. The design was a pretest-posttest design, including retrospective preratings. Subjects were 73 psychology freshmen fulfilling a course requirement. Subjects were led to believe that the veracity of their self-reports could be checked by means of objective measures. The bogus-pipeline induction in the pretesting did lower self-repo…
A constructive replication of White's alleged refutation of Nisbett and Wilson and of Bem: Limitations of verbal reports of internal events
Effectiveness of Communication Skills Training for Dental Students
A three-day communication-skills training was given to first-year dental students. The remaining first-year students were exempted from instruction and acted as a control group. To assess the effect of the short-term training a videotape of 28 fragments was shown shortly after the training course. Each fragment represented a dentist-patient interaction and ended with a statement by the patient. Per fragment the students were allowed 40 sec. to wr…
Significance as a determinant of interest in scientific research
Group Cohesion, Task Performance, and the Experimenter Expectancy Effect
Three laboratory experiments were done to study the effects of cohesion on task fulfillment and to explore the influence of task fulfillment on the initial level of cohesion. Within four-person groups of freshmen psychology students, cohesion was manipulated successfully by a triple procedure. The level of cohesion was ascertained directly after the induction treatment and again after task fulfillment. Group and individual ability tasks were used…
