- This study investigated the reported conditioned or cognitive origin of dental phobia in 100 adult patients at a specialized dental phobia clinic. It was shown that a majority of patients reported a conditioned background to their dental fear. Patients' avoidance time and level of dental anxiety corresponded to previously reported data for fearful groups. Individuals with an arousal conditioning etiology of dental fear reported significantly longer avoidance time as compared to individuals with a cognitively learned reaction. With the exception of an elevated level of general fears, most psychometrically assessed emotional reactions were well within normal ranges. However, patients with a non-conditioned, cognitive etiology reported significantly higher levels of trait anxiety and fear of embarrassment. In addition, a separate analysis among women revealed a greater fear of physical injuries among patients with cognitive etiology.

- This study investigated a screening procedure for psychologic distress in adult patients with dental phobia before treatment of dental fear. The screening procedure was performed among 191 individuals in consecutive steps and included a medical/dental history, psychologic interviewing, and testing. Data collected during this process were analyzed and compared with SCL-90(R) data. The screening process was successful in selecting individuals without major psychologic distress problems. Among the excluded patients 91% had general symptoms scores on the SCL-90(R) exceeding a normative population mean, and 95% of included patients had a mean lower than an average for psychiatric outpatients. There were statistically significant differences between included and excluded patients on all subdimensions of the SCL-90. Thus, excluded patients had higher levels of psychologic distress, poorer psychosocial background, and more psychosomatic symptoms. This was accompanied by higher levels of negative attitudes toward dentists and their performance of dentistry, whereas no significant differences were found among the dental fear measures used.

- A fear survey instrument, based on the Fear Survey Schedule-II and five additional fear items, was administered to 109 patients (70 women and 39 men) on a waiting list at a specialized dental fear clinic. The fear survey was analyzed to identify its factorial structure. Five fear factors, explaining 54% of the total variance, were identified concerning areas of "illness and death", "failures and embarrassment", "social situations", "physical injuries", and "animals and natural phenomena". An ad hoc reduction of items was carried out to form a shorter, more practical to use questionnaire, which resulted in factors of four or five items with loadings greater than 0.50. The factors intercorrelated significantly (rp varying between 0.33 and 0.59) and "illness and death" correlated highly with "physical injuries" (rp = 0.59) and "animals and natural phenomena" (rp = 0.56), while "failures and embarrassment" correlated highly to "social situations" (rp = 0.54). Statistically significant, but generally lower correlations were found between each factor and the dental fear measures. The highest correlations were found between fear of "physical injuries" and dental fear. There was also a high and significant correlation between sex and fear of "animals and natural phenomena".

- Adsorption and orientation properties of two different types of immunoglobulin molecules on derivatized and native mica surfaces were investigated using TM-AFM. The analyses included height measurements at two different pH values and a new technique, presented here as threshold analysis, which displays the outer mantle shape of an adsorbed protein. A major difference in preferential orientation is observed upon comparing the adsorption of the two proteins onto the different surfaces. The characteristics of both the adsorbed immunoglobulin and the surface are important for any preferential orientation of the adsorbed protein.

- This study aims to evaluate within-individual changes over time in work-role quality and quality of life and the relationship of these qualities to self-reported health as experienced by women in a male-dominated industry. Forty-seven women completed a questionnaire at two different points in time. The results showed evidence of a relationship between work-role quality and quality of life and self-reported health. There was a connection between changes in environmental demands and changes in musculoskeletal symptoms and between changes in quality of life and changes in gastrointestinal symptoms, except for psychological distress. The difference in medical symptoms is hypothesized to be an effect of hormonal signals. Four strategically selected women, who indicated improved or impaired health, were interviewed about their working situations. A tentative theoretical model was set up for perceptions of health.

- The psychological assessment of chronic pain is often accomplished using questionnaires such as the (West Haven-Yale) Multidimensional Pain Inventory ((WHY)MPI) which is constructed to capture the multidimensionality of chronic pain. The (WHY)MPI theoretically originates from behavioural and cognitive behavioural theories of pain. It is divided into three parts and measures psychosocial and behavioural consequences of pain. This questionnaire has displayed satisfactory psychometric properties and translations of the original English version into German and Dutch have been demonstrated to be reliable and valid. The aim of this study was to test the reliability and factor structure of a Swedish translation of the (WHY)MPI, the MPI-S, and also to test the generalisability of the factor structure found for the (WHY)MPI. We performed analyses of internal consistency using Cronbach's alpha, and carried out a confirmatory factor analysis (CFA) employing LISREL-8 on a population of 682 patients suffering from chronic musculoskeletal pain. Test-retest analysis was accomplished on a sub-sample of 54 individuals taken from the aforementioned population. For sections 1 and 2 of the MPI-S the overall reliability and stability were good, and after the exclusion of four items, the factor structure was similar to other versions of the MPI. For section 3, despite removal of five questions, the proposed factor structure could not be replicated. This part of the inventory is designed to measure the extent of different types of activities, and our results suggest that this section may only be used for assessing general activity level. We conclude that, with a few adjustments, the analyses yielded satisfactory results for sections 1 and 2 of the MPI-S regarding its factor structure, reliability and generalisability. For section 3 the hypothesised factor structure could not be confirmed.
