Characteristics and motives of women choosing elective induction of labour.

Personal characteristics of healthy term pregnant women who chose elective induction or spontaneous onset of labour and the motives for their choice were assessed. Almost 50% of 237 women with uncomplicated pregnancies opted for elective induction when offered the opportunity. These women appeared to have had more complaints during their pregnancy and menstrual periods, more complications in their obstetrical history and to be more anxious about their labour than women who chose a spontaneous onset of labour. Predominant motives were a feeling of safety and the desire to shorten the duration of pregnancy. These characteristics and motives seem to reflect a lack of trust in physical reproductive functions. It is concluded that in evaluating effects of elective induction of labour, pre-existing differences between women who choose elective induction and women who opt for a spontaneous onset must be taken into account.

Clinical study of so-called unconscious perception during general anaesthesia.

Ninety-one patients undergoing biliary tract surgery were randomly assigned to one of three treatment groups in which different sounds were administered, by means of earphones, in a double-blind design. The effects of the administration of positive suggestions, noise or operating theatre sounds on the postoperative course were studied. Results showed that exposure to positive suggestions during general anaesthesia, as compared with noise or operating theatre sounds, protected patients older than 55 yr against prolonged postoperative stay in hospital.

Changes in the attitude of general practitioners as a result of participation in a Balint group.

An investigation was carried out in an attempt to measure whether there were any limited changes in a doctor's personality as a result of participation in a Balint group. Twenty-two general practitioners applied originally to join two Balint groups. After two years the groups had been combined and only eight doctors were still participating. A questionnaire was designed in order to measure changes in personality. The conclusion was that the personality of the doctor did not change fundamentally as a result of participating in a Balint group. But, it could be said that working in the group gradually lead the participants to deal with their patients in a different and more competent manner. The participants became aware of the fact that patients were much more problematical than they originally thought. In the end the participants were able to deal with this insight in a competent way. It emerged from the investigation that a considerable shift had taken place in the type of patients with whom the doctor said they had difficulty. There were some characteristics of patients--an average of 5.13 per doctor--with which the doctors had difficulty at both the beginning and at the end of the course; an average of 6.38 characteristics had disappeared, but their place had been taken by an average 3.25 other characteristics. At an individual level the differences were extremely large.

Psychologic correlates of dental anxiety.

In an attempt to establish the relationships between dental anxiety and personality traits, such as neuroticism and locus of control, a survey has been carried out among 30-40-yr-olds in a Dutch town. In the first instance, the questionnaires comprising the psychologic items were treated by Non-Metric Principal Components analysis to detect the underlying structure. The principal components found were then used in a second-stage analysis. The results appear to be at variance with the literature, i.e. subgroups discernible in the sample by sets of psychologic features were not associated with dental anxiety categories.

Clinical measurement of dental anxiety.

The mean scores on five dental anxiety measurements of 60 patients suffering from extreme dental anxiety are compared with those of an equal-sized, matched group of regular dental attenders free from dental anxiety. Four of the measurements, especially Corah's DAS, appear to be suitable for distinguishing persons suffering from extreme dental anxiety. Also, persons with extreme dental anxiety appear to express their fear openly.

Dimensionality of dental anxiety measurements.

A survey among 620, 30-40-yr-olds, was carried out in order to measure dental anxiety with Corah's DAS, Weiner's AALC, and some other questions on anxiety, among which was the duration of psychophysiologic responses prior to a dental appointment. The data were analyzed with a Non Metric Components analysis. The DAS turned out to be unidimensional. The AALC on the other hand appeared to contain four components. A second stage analysis comprising the DAS component, the four AALC components, and the remaining variables revealed a two-dimensional structure, of which only the first component is dentistry related. This component showed better differentiation of the respondents than with DAS or AALC alone. Part of AALC's questions and a question about anxiety in daily life proved to be superfluous for measuring dental anxiety. It is concluded that dental anxiety and anxiety in general have to be measured with questions covering different aspects.

Influence of repression upon the measurement of dental anxiety.

Using a non-linear, multivariate analysis, the resistance against admitting to being dentally anxious was studied. Dental anxiety was found to be repressed by a subgroup, among them more men than women, of a sample, who also repressed the feeling of low self esteem about tooth loss. Based on the results, regular and irregular dental attenders can be separated almost perfectly. The relationship with other anxiety measurements, i.e. Corah's Dental Anxiety Scale and three components discernible in Weiner's Anticipation Anxiety Level Chart, was studied.

Sociodemographic correlates of dental anxiety.

In a survey comprising 620 30-40-yr-old inhabitants of a Dutch town, dental anxiety was measured along with some sociodemographic variables. The data were analyzed in an attempt to reveal associations between sociodemographically determined groups of respondents and their scores on the different measurements of dental anxiety. Women reported higher dental anxiety levels than men, with the exception of body damage anticipation anxiety. The rank order of birth seemed to have no influence. Divorced men and women reported a higher anxiety level on two of the anxiety measurements, but the association appeared to be weak. A lower level of education, irregular dental attendance, and edentulousness appeared to be associated with a higher level of dental anxiety.

Elective induction of labor: a prospective clinical study, II: Psychological effects.

Several authors have stated that induction of labor may have deleterious psychological effects on women's experiences of labor and early mother-infant interaction. Research on this subject is scarce and in most cases no distinction is made between elective induction and induction for medical reasons. For that reason the observed effects may also have been caused by the medical complications that led to the induction. Differences in experience of labor may also be in part explained by differences in personal characteristics between women choosing or rejecting induction of labor. Influences of induction of labor can only be reliably assessed in prospective studies. In the present study of 271 women with an uncomplicated pregnancy, data regarding their experiences of pregnancy and their expectations of labor and motherhood were collected before labor. In 72 women labor was electively induced, and 199 women had a spontaneous onset of labor. Of 33 women, 19 with spontaneous labor and 14 with elective induction, the first contact with their newborn was observed. All women who could be contacted were interviewed about their experience of labor and the first contact with their infant. Six months after delivery the mothers were questioned about the state of health of mother and infant and about nursing the infant. Mothers with induced labor were rated as being generally less emotionally involved in the first contact with their newborn than mothers with spontaneous labor, but the differences were not significant (Fig. 1). The duration of spontaneous labor was longer, but the subjective time experience did not differ between groups. Women with spontaneous labor were more tired during labor.(ABSTRACT TRUNCATED AT 250 WORDS)

Dental anxiety, the parental family and regularity of dental attendance.

A survey was carried out among 25-yr-old inhabitants of Amsterdam in order to study the relationship between regularity of dental attendance on the one hand and dental anxiety, dental upbringing of the respondents, dental behavior of the parents, education, sex, and the interactions between these independents, on the other. The data were analyzed hierarchically with regression analysis, the logistic approach. Dental anxiety, sex, dental upbringing and the interaction between education and anxiety, in that order, were found to be of importance for the prediction of regularity of dental attendance. Two other terms, though lacking substantial standardized regression coefficients, namely education and the interaction between education and dental upbringing, are also present in the model found. The prediction of one being a regular attender is satisfactory, but the classification of the irregular attenders is disappointing. The effect is discussed of the rather large non-response and attention is given to the effect of dental upbringing in regard to coping resources in the dental situation. It has to be concluded that other factors must be included to achieve an improvement of the classification of the irregular attenders. Dental anxiety, although of importance, cannot account for an adequate differentiation between regular and irregular attenders.
