Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Objectives.The general objectives of this dissertationwere to examine the effects of acute exposure to meaningfulirrelevant speech and road traffic noise on memory performance,and to explore annoyance responses to noise exposure in theschool environment for pupils and teachers in different agegroups.Methods. The thesis comprises seven papers, representingdifferent methodological approaches: experiments, surveystudies and interviews. In the experiments, reported in PapersI-V, 288 pupils and teachers participated in the age groups,13-14 years (n=96), 18-20 years (n=96), 35-45 years (n=48) and55-65 years (n=48). The subjects were randomly assigned to oneof three conditions: (a) meaningful irrelevant speech, (b) roadtraffic noise, and (c) silence. The equivalent sound level inthe noise conditions was set to 66 dB(A). A test batteryreflecting episodic and semantic memory were used. The surveystudies, reported in Paper VI and VII, included 207 pupils(M=13.5) and 166 teachers (M=45.9). Two separate questionnairesmainly comprising items about annoyance, noise sensitivity andstress symptoms were administered. Paper VI presents results offocus group interviews (n=16) treating the main topics:disturbing sounds, emotions, ongoing activity, and suggestionsconcerning future changes. Results. The overall findings showedthat both noise sources affected episodic and semantic memoryto the same degree for all age groups. The results indicatedthat the similarity of semantic content between noise and thetask at hand was not the only suitable explanation model, sincea non-speech noise impaired memory as much as speech.Resultsalso indicated that attention effects did notmediate the obtained noise effects and that the noise effectsdid not differ between age groups. Therefore, it seemedunlikely that different memory and attentional capacities stoodout as explanatory factors of the memory effects. Sinceperformances of both episodic and semantic memory tasks wereimpaired, the explanation based on level of access to long-termmemory was also ruled out. However, the episodic memory task,reading comprehension, stood out to be most impaired by noise,suggesting that complexity of the task to perform was ofimportance. For reading comprehension there was also adifferent noise pattern obtained. Participants performance wasin this task, more impaired by meaningful irrelevant speechthan by road traffic noise. This effect indicated thatmeaningful irrelevant speech might reduce the availablecognitive resources necessary for learning the text. Theannoyance models derived from the survey studies indicated thatsensitivity acted as a mediator between hearing status andannoyance, with stress symptoms as an outcome. Whetherannoyance arises or not was also determined by control andpredictability of the noise. In the interviews a differentannoyance pattern was found, in that stress symptoms appearedto be a determinant of annoyance. To be involved, respected,take own responsibility and respect others were suggestions onhow to change the environment to become more silent.Conclusions.For both pupils and teachers acute exposureto meaningful irrelevant speech and road traffic noiseinfluenced both the achieving and providing of knowledge. Acommon annoyance pattern was also found for pupils andteachers, where individual and situational factors were ofimportance. To achieve a more silent school environment in thefuture, the pupils pointed out that the interaction betweenthemselves and their teachers was of importance.Key words:Noise, meaningful irrelevant speech, roadtraffic noise, memory, age groups, school environment, pupils,teachers

- BackgroundAutonomy is recognized as important for individual well-being and constitutes one dimension in the KIDSCREEN-instrument measuring health related quality of life (HRQoL) in children and adolescents. However, the autonomy questions in KIDSCREEN are restricted to opportunities to influence leisure time activities, which is a form of autonomy as volition. Yet, there are other aspects of autonomy that might be related to adolescent’s HRQoL. The aims of the present study were first to investigate the psychometric properties of a scale measuring autonomy in adolescence from a control perspective (AAC) including its relation to the autonomy dimension in KIDSCREEN, and second; to investigate AACs ability to predict each of the 10 dimensions constituting KIDSCREEN.MethodsStudents (n = 154) aged 15–16 years who were recruited from schools located in both low (two schools) and high (two schools) socioeconomic status (SES) areas in Sweden participated in a cross-sectional study. The adolescents answered a questionnaire including a new 6-item scale measuring perceived autonomy and HRQoL assessed by the KIDSCREEN-52 instrument. A factor analyses was computed to investigate the relation between the items in the AAC scale and the autonomy items in the KIDSCREEN instrument. Hierarchical regression analyses were computed to investigate if the AAC scale predicted HRQoL in any of the 10 dimensions in KIDSCREEN after controlling for gender, SES and the original autonomy scale included in KIDSCREEN.ResultsThe factor analysis showed that all the items from the autonomy scale loaded in one factor and that all the items from the AAC scale loaded in another dimension. The hierarchical regression models showed that the AAC scale uniquely predicted HRQoL in all dimensions of the KIDSCREEN instrument after controlling for gender, SES and the original autonomy scale included in KIDSCREEN-52. A high level of perceived autonomy was associated with a high level of HRQoL for both scales.ConclusionA new scale for measuring autonomy from a control perspective has been presented and shown to differ from autonomy as volition. Both forms of autonomy are positively related to HRQoL in adolescence 15–16 years old.

- Self-determination theory proposes that all humans have three intrinsic psychological needs: the needs for Autonomy, Competence, and Relatedness. These needs take different forms in different areas of life. The present study examines the psychometric properties of a Swedish version of the Basic Psychological Need Satisfaction at Work (BPNS-W) scale. The fit of 10-factor structures previously suggested for related versions of the scale were compared. Cross-sectional data from 1,200 participants were examined in a confirmatory factor analysis framework. Both the original 21-item version and a reduced 12-item version of the BPNS-W were examined. The General Health Questionnaire was used for validation. The results supported a three-factor solution with correlated error variances for the reversed items. Invariance testing of the long and short scales gave best support to the short scale, for which partial scalar invariance was achieved. The external validity of the short scale was supported by a hierarchical regression analysis in which each need made a unique contribution in predicting psychological well-being. In conclusion, the results corroborate a three-factor structure of BPNS-W. Although not perfect the short scale should, it is argued, be preferred over the long version. Directions for the future development of the scale are discussed.

- Background: Long-term sick leave due to common mental disorders (CMDs) is a great burden in several countries. Women are more likely to be affected by CMDs. A strong intention to return to work (RTW) as well as symptom relief may facilitate RTW in this group. However, there is a lack of knowledge regarding what constitutes a strong intention. The Theory of Planned Behaviour is well-suited to identifying underlying beliefs about intentions to perform a behaviour. By including psychological well-being and perceived health, a more comprehensive picture of determinants of RTW intention might be achieved. Thus, the aim of the present study was to identify associations between RTW beliefs, psychological well-being, perceived health and RTW intentions among women on long-term sick leave due to CMDs, and to do so based on the Theory of Planned Behaviour.Methods: The study was cross-sectional. Between October 2019 and January 2020, 282 women on long-term sick leave (>2 months) due to CMDs were included in the study. The questionnaires for data collection were: “RTW Beliefs Among Women-Questionnaire”, the “General Health Questionnaire -12” and the “EuroQol Visual Analogue Scale”. Standard multiple regression analysis was performed both with and without adjustment for potential confounders.Results: The results showed that more positive attitude towards RTW, stronger social pressure to RTW, higher perceived control over RTW and higher psychological well-being were associated with stronger RTW intention. The adjusted analysis eliminated the importance of psychological well-being for RTW intention, but showed that women who reported that their employer had taken actions to facilitate their RTW had stronger RTW intention. Conclusion: The RTW beliefs, derived from the Theory of Planned Behaviour, were all important for a strong RTW intention, while psychological well-being and perceived health showed weaker associations. Furthermore, having an employer that take actions for facilitating RTW was associated with stronger RTW intentions. Though some caution is warranted regarding the representativeness of the sample, the results do improve our understanding of some important determinants of RTW intention among women on long-term sick leave for CMDs.
