Radiographers’ Professional Competence : Development of a context-specific instrument

Andersson, Bodil T. January 2012 (has links)
Aims: The overall aim of this thesis was to explore and describe radiographers‟ professional competence based on patients‟ and radiographers‟ experiences and to develop a context-specific instrument to assess the level and frequency of use of radiographers‟ professional competence. Methods: The design was inductive and deductive. Both qualitative and quantitative methods were used. The data collection methods comprised interviews (Studies I-II) and questionnaires (Studies III-IV). The subjects were patients in study I and radiographers in studies II-IV. In study I, 17 patients were interviewed about their experiences of the encounter during radiographic examinations and treatment. The interviews were analysed using qualitative content analysis. In study II, 14 radiographers were interviewed to identify radiographers‟ areas of competence. The critical incident technique was chosen to analyse the interviews. Studies III and IV were based on a national cross-sectional survey of 406 randomly selected radiographers. Study III consisted of two phases; designing the Radiographer Competence Scale (RCS) and evaluation of its psychometric properties. A 42-item questionnaire was developed and validated by a pilot test (n=16) resulting in the addition of 12 items. Thus the final RCS comprised a 54-item questionnaire, which after psychometric tests was reduced to 28 items. In study IV, the 28-item questionnaire served as data. The level of competencies was rated on a 10-point scale, while their use was rated on a six-point scale. Results: In study I, the female patients‟ comprehensive understanding was expressed as feelings of vulnerability. The encounters were described as empowering, empathetic, mechanical and neglectful, depending on the radiographers‟ skills and attitudes. Study II revealed two main areas of professional competence, direct patient-related and indirect patient-related. The first focused on competencies in the care provided in close proximity to the patient and the second on competencies used in the activities of the surrounding environment. Each of the two main areas was divided into four categories and 31 sub-categories that either facilitated or hindered good nursing care. In study III the analysis condensed the 54-item questionnaire in two steps, firstly by removing 12 items and secondly a further 14 items, resulting in the final 28-item RCS questionnaire. Several factor analyses were performed and a two factor-solution emerged, labelled; “Nurse initiated care” and “Technical and radiographic processes”. The psychometric tests had good construct validity and homogeneity. The result of study IV demonstrated that most competencies in the RCS received high ratings both in terms of level and frequency of use. Competencies e.g. „Adequately informing the patient‟, „Adapting the examination to the patient‟s prerequisites and needs‟ and „Producing accurate and correct images‟ were rated the highest while „Identifying and encountering the patient in a state of shock‟ and „Participating in quality improvement regarding patient safety and care‟ received the lowest ratings. The total score of each of the two dimensions had a low but significant correlation with age and years in present position. The competence level correlated with age and years in present position in both dimensions but not with the use of competencies in the “Nurse initiated care” dimension. Conclusion: This thesis has shown that professional competence is important in the encounter between patient and radiographer. It has also demonstrated that radiographers‟ self-rated professional competence is based on nursing, technological and radiographic knowledge. From a radiographer‟s perspective, „Nurse initiated care‟ and „Technical and Radiographic processes‟ are two core dimensions of Radiographer Competence Scale. The 28-item questionnaire regarding level and frequency of use of competence is feasible to use to measure radiographers‟ professional competence.

Intellectual Disability and Mental Health Problems : Evaluation of Two Clinical Assessment Instruments, Occurrence of Mental Health Problems and Psychiatric Care Utilisation

Gustafsson, Carina January 2003 (has links)
It has been suggested that persons with intellectual disabilities (ID) manifest the full range of mental health problems. The main purpose of this thesis is to adapt and evaluate two clinical assessment instruments and to investigate the occurrence of mental health problems as well as psychiatric care utilisation in persons with ID. The psychometric properties of a Swedish version of the two instruments [Reiss Screen for Maladaptive Behaviour (RSMB) and the Psychopathology Inventory for Mentally Retarded Adults (PIMRA)] were investigated in a random, institutional and clinical sample of administratively defined (ADDEF) adults with ID (n = 199). The analyses suggest that the RSMB could be used as intended by staff as a primary screening device for the identification of mental health problems in persons with ID, and that the PIMRA had a potential to identify individuals with a specific mental disorder. The psychometric evaluation reveals that the Swedish versions of the RSMB and PIMRA measure a construct related to the diagnostic categories in the DSM-III-R and DSM-IV. This construct could be conceptualised as mental health problems. The RSMB and PIMRA results show that the overall occurrence of mental health problems in ADDEF samples of persons with ID (175 men and 148 women) ranged from 34 to 64%. The preliminary level of ID was mild (23%), moderate (39%) and severe (38%). The most common mental health problems were aggressive and self-injurious behaviours, depression, anxiety and adjustment disorders. In registered patients receiving out- or in-patient psychiatric care the occurrence of adults with an ICD-10 diagnosis of ID was approximately 1% (70 to 90% had a mild level of ID). In contrast to the high frequency of mental health problems reported, psychiatric care was used infrequently. This tendency is particularly evident in persons with moderate and severe ID.

Fibromyalgia and self-regulatory patterns : development, maintenance or recovery in women

Wentz, Kerstin January 2005 (has links)
Aims: The overall aim of this thesis was to elucidate psychological processes and development, maintenance or recovery related to fibromyalgia based on in depth interviews. In a next step women with fibromyalgia, women without long-lasting pain and women with long-lasting pain were compared using psychometric instruments selected or developed based on qualitative results. Methods: Twenty-one women with fibromyalgia and 8 women recovered were interviewed. Their narrations were analysed using Grounded Theory. Tentative theory was built. The I Myself Scale (IMS) was constructed to mirror self-regulation prior to onset of symptoms and complemented with an instrument on current self-regulation: Structural Analysis of Social Behaviour (SASB) and SF-36 mirroring health related quality of life, regarding the two pain groups. The groups were compared using analysis of variance, principal components analysis paired with discriminant analysis and profile analysis. Results: Analyses of the interviews resulted in core concepts of an “unprotected self” (current fibromyalgia) or a “strong but not enough to be weak” self (recovery). Data patterns indicated that the women as children were unprotected in relation to stimuli and affects. Relationships with the parents were characterised by strain and low levels of support. The recovery group had as children simultaneously been able to develop obvious competence and capability to receive help. Psychological vulnerability was in adult life compensated for through pronounced helpfulness and dissociation/repression including intense activity. An increase in mental load such as localised pain or psychosocial crisis preceded onset of fibromyalgia accompanied by impaired cognitive functioning. The state of fibromyalgia meant maintained high levels of mental load such as difficulties of the selfstructures, impaired cognitive functioning and somatic symptoms. The recovery group experienced substantial social support and often used mastering strategies to ease symptoms. A decrease in strain as improved life conditions and cease of overexertion preceded recovery. Health was thereafter maintained through careful management as seeking low levels of strain and pacing of activity. Recovery ‘on parole’ also meant personal growth and use of efficacious defences. Psychometrical testing confirmed qualitative data patterns of self-regulation connected to fibromyalgia. Impaired selfreference/ understanding of health needs and others not being asked for help and advice was reported before onset of symptoms. Dissociation or repression including intense activity and self-loading were also employed. SASB and SF-36 indicated that women with fibromyalgia experienced higher levels of mental “load” than the other pain group. Conclusion: Qualitative data indicated that life prior to onset of fibromyalgia and current fibromyalgia held qualities of impaired self-regulation in relation to mental and physical load. The state of recovery relied on improved self-regulation allowed by conditions of life. Quantitative data patterns confirmed qualitative results on impaired self-protection before onset of fibromyalgia and a specifically high level of mental load during the state of fibromyalgia. Psychological disregulation is discussed and hypothesised to cause but also later in the process parallel alterations in somatic homeostatic functions. Recovery could mean that biological regulation regarding strain is replaced with more of “psycho-social” regulation as careful pacing of work. Implications for treatment are suggested.

Development and Testing of an Instrument to Measure the Quality of Children’s End-of-life Care from the Parents’ Perspective

Widger, Kimberley Ann 31 August 2012 (has links)
Background: The Senate of Canada asserts that quality end-of-life care is the right of every Canadian. Yet, little is known about the quality of end-of-life care for dying children and their families. Purpose: The study purpose was to develop and test an instrument to measure parents’ perspectives on the quality of care provided to families before, at the time of, and following the death of a child. Methods: In study Phase I, key components of quality pediatric end-of-life care were synthesized through a systematic review of research literature then validated and extended through focus groups with bereaved parents. In Phase II, instrument items were developed to assess structures, processes, and outcomes important to quality end-of-life care, then tested for content and face validity by health professionals and bereaved parents. In Phase III, the instrument was administered to bereaved mothers from across Canada and psychometric testing conducted. Results: Instrument items were developed based on review of 67 manuscripts and 3 focus groups with 10 parents. The Content Validity Index for the instrument was 0.84 as assessed by 7 health professionals. The instrument was assessed by 6 bereaved parents for face and content validity as well as their cognitive understanding of the items. In the final phase, 128 mothers completed the instrument and 31 of those completed it twice. Initial evidence for test-retest reliability, internal consistency, and construct validity was demonstrated for 7 subscales: Connect with Families, Involve Parents, Share Information with Parents, Share Information among Health Professionals, Support Parents, Provide Care at Death, and Provide Bereavement Follow-up. Additional items with demonstrated content validity only were grouped into three domains: Support the Child, Support Siblings, and Structures of Care. Implications: This study is a significant step forward in comprehensive measurement of the quality of children’s end-of-life care. The instrument provides a mechanism for feedback to health professionals, health systems, and policy makers to improve care provided to families facing the death of a child.

Do cognitive responses to how we feel really matter? : a psychometric evaluation and experimental extension of the Responses to Positive Affect questionnaire (RPA)

Engh, Johannes, Olofsson, Malin January 2011 (has links)
This study aims to investigate cognitive response styles to positive affect. A Swedish version of the Responses to Positive Affect questionnaire (RPA) was psychometrically evaluated and experimentally tested as participants were mood induced. The 3-factor model for the RPA questionnaire (Self-focused positive rumination, Emotion-focused positive rumination and Dampening) was replicated, and the RPA was further explored through analyses of convergent and incremental validity. The experimental results revealed that the two positive rumination subscales had a strong relationship with each other and current positive affect. However, none of the RPA subscales functioned as moderators in the relationship between cognitive response style and participants’ mood reactivity.

Inter-rater Reliability of the Anxiety Disorders Interview Schedule for DSM-IV in High Functioning Children and Adolescents with Autism Spectrum Disorder

Ung, Danielle 01 January 2012 (has links)
The present study examined inter-rater agreement on the Anxiety Disorder Interview Schedule DSM-IV Child and Parent Interview (ADIS-IV-C/P) in youth with autism spectrum disorder and if age and ASD diagnosis moderated agreement. Diagnoses established for 70 7-16-year-old youth with ASD during a live administration of the ADIS-IV-C/P were compared to diagnoses identified by a second rater after listening to audiotaped recordings of the interviews. Inter-rater agreement on parent and child reports was excellent (k=1.00). Inter-rater agreement on principal diagnoses (k=0.91), individual anxiety diagnoses (k=0.85-0.97), and other comorbid diagnoses (i.e., major depressive disorder, dysthymia, oppositional defiant disorder, attention deficit hyperactivity disorder-Inattention/Hyperactivity/Combined Type) (0.89-1.00) were excellent; agreement did not differ as a function of ASD diagnosis or age. Results suggest that the anxiety disorders and comorbid disorders assessed by the ADIS-IV-C/P can be diagnosed by pairs of clinicians with good reliability.

Peer student group interaction within the process-product paradigm

Bobrink, Erik January 1996 (has links)
The main purpose of this dissertation was to relate a study within the framework of Peer Student Group Research to the basic Process-Product Paradigm for Research on Teaching. Information about previous research within this field was given in the chapter on background. A total of 287 peer students at the Department of Education, Umeå University and at the teacher training colleges at Umeå and Luleå participated in this study. Thirty-one students worked individually and constituted a control group. The remaining 256 students were divided into 64 groups. Each group consisted of four students and was videoed during the problem-solving phase (60 minutes). The task dealt with a discipline case in the Swedish compulsory school. This case was discussed on the basis of four different psychological theories. A 2(Content, Group vs. Individual Content) X 2(Cohesiveness, High vs. Low Cohesiveness) X 2(Credit, Group vs. Individual Credit) design was used. A mediating model, i.e. Contribution(Analytical vs. Structural Contribution) X Persistence(Task Persistent vs. Task Non-Persistent Contribution) was used to observe the processes. Two of the videoed groups were analysed naturalistically. The results were measured psychometrically by means of an ANOVA. The ANOVA analysed main effects and interactions between the factors for the four process variables and for the product variable. The results of this study revealed the importance of studying Educational Productivity, i.e. both the process and the product. Furthermore, the study demonstrated that interactions could be discovered with psychometric methods but not with naturalistic methods. On the other hand, the naturalistic method revealed more sensitively how the group members worked and how they attempted to solve their task. The traditional assumption of group work vs. individual work was falsified. Individuals did better than groups on this type of problem. The results were discussed in both psychometric and naturalistic terms. / <p>Diss. Umeå : Umeå universitet, 1996</p> / digitalisering@umu
