- An on-road study was conducted to evaluate a complementary tactile navigation signal on driving behaviour and eye movements for drivers with hearing loss (HL) compared to drivers with normal hearing (NH). 32 participants (16 HL and 16 NH) performed two preprogrammed navigation tasks. In one, participants received only visual information, while the other also included a vibration in the seat to guide them in the correct direction. SMI glasses were used for eye tracking, recording the point of gaze within the scene. Analysis was performed on predefined regions. A questionnaire examined participant's experience of the navigation systems. Hearing loss was associated with lower speed, higher satisfaction with the tactile signal and more glances in the rear view mirror. Additionally, tactile support led to less time spent viewing the navigation display.

- [1] A unified scheme to assign pollen samples to vegetation types was used to reconstruct vegetation patterns north of 55degreesN at the last glacial maximum (LGM) and mid-Holocene (6000 years B. P.). The pollen data set assembled for this purpose represents a comprehensive compilation based on the work of many projects and research groups. Five tundra types (cushion forb tundra, graminoid and forb tundra, prostrate dwarf-shrub tundra, erect dwarf-shrub tundra, and low- and high-shrub tundra) were distinguished and mapped on the basis of modern pollen surface samples. The tundra-forest boundary and the distributions of boreal and temperate forest types today were realistically reconstructed. During the mid-Holocene the tundra-forest boundary was north of its present position in some regions, but the pattern of this shift was strongly asymmetrical around the pole, with the largest northward shift in central Siberia (similar to200 km), little change in Beringia, and a southward shift in Keewatin and Labrador (similar to200 km). Low- and high-shrub tundra extended farther north than today. At the LGM, forests were absent from high latitudes. Graminoid and forb tundra abutted on temperate steppe in northwestern Eurasia while prostrate dwarf-shrub, erect dwarf-shrub, and graminoid and forb tundra formed a mosaic in Beringia. Graminoid and forb tundra is restricted today and does not form a large continuous biome, but the pollen data show that it was far more extensive at the LGM, while low- and high-shrub tundra were greatly reduced, illustrating the potential for climate change to dramatically alter the relative areas occupied by different vegetation types.

- For some forty years the eye-tracking technology has facilitated the study of eye movement patterns for sighted people during reading and other visual activities. Today – a newly developed automatic finger tracking system makes it possible to reconstruct blind people’s tactile reading in real time and to automatically analyze finger movements during Braille text reading and tactile picture recognition. In this case study, the very first automatic finger tracking system is presented together with results indicating how Braille readers can increase awareness of their own reading styles. This opens up for future Braille education to become more evidence-based and, at the same time, for a new research field: contrastive studies of language in its auditory, visual and tactile manifestations.

Tidskriftsartikel (refereegranskat)abstract
- Aims Left ventricular (LV) dysfunction can be triggered by non-cardiac disease, such as sepsis, hypoxia, major haemorrhage, or severe stress (Takotsubo syndrome), but its clinical importance is not established. In this study, we evaluate the incidence and impact on mortality of LV dysfunction associated with critical illness. Methods and results In this single-centre, observational study, consecutive patients underwent an echocardiographic examination within 24 h of intensive care unit (ICU) admission. LV systolic dysfunction was defined as an ejection fraction (EF) < 50% and/or regional wall motion abnormalities (RWMA). A cardiologist assessed patients with LV dysfunction for the presence of an acute or chronic cardiac disease, and coronary angiography was performed in high-risk patients. Of the 411 patients included, 100 patients (24%) had LV dysfunction and in 52 (13%) of these patients, LV dysfunction was not attributed to a cardiac disease. Patients with LV dysfunction and non-cardiac disease had higher mortality risk score (Simplified Acute Physiologic Score 3 score), heart rate, noradrenaline doses, and lactate levels as well as decreased EF, stroke volume, and cardiac output compared with patients with normal LV function. Diagnoses most commonly associated with LV dysfunction and non-cardiac disease were sepsis, respiratory insufficiency, major haemorrhage, and neurological disorders. RWMA (n = 40) with or without low EF was more common than global hypokinesia (n = 12) and was reversible in the majority of cases. Twelve patients had a circumferential pattern of RWMA in concordance with Takotsubo syndrome. Crude 30 day mortality was higher in patients with LV dysfunction and non-cardiac disease compared with patients with normal LV function (33% vs. 18%, P = 0.023), but not after risk adjustment (primary outcome) {odds ratio [OR] 1.56 [confidence interval (CI) 0.75-3.39], P = 0.225}. At 90 days, crude mortality was 44% and 22% (P = 0.002), respectively, in these groups. This difference was also significant after risk adjustment [OR 2.40 (CI 1.18-4.88), P = 0.016]. Conclusions Left ventricular systolic dysfunction is commonly triggered by critical illness, is frequently seen as regional hypokinesia, and is linked to an increased risk of death. The prognostic importance of LV dysfunction in critical illness might be underestimated.

Can psychotherapists function as their own controls? Meta-analysis of the crossed therapist design in comparative psychotherapy trials
- 2013

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVE:Clinical trials sometimes have the same therapists deliver more than 1 psychotherapy, ostensibly to control for therapist effects. This "crossed therapist" design makes controlling for therapist allegiance imperative, as therapists may prefer one treatment they deliver to the other(s). Research has established a strong relationship between principal investigators' allegiances and treatment outcome. Study therapists' allegiances probably also influence outcome, yet this moderating factor on outcome has never been studied.DATA SOURCES:English language abstracts in PsycINFO and MEDLINE from January 1985 to December 2011 were searched for keywords psychotherapy and randomized trial.STUDY SELECTION:The search yielded 990 abstracts that were searched manually. Trials using the same therapists in more than 1 condition were included.DATA EXTRACTION:Thirty-nine studies fulfilled inclusion criteria. Meta-regression analyses assessed the influence of researchers' allegiance on treatment outcome, testing the hypothesis that studies poorly controlling for therapist allegiance would show stronger influence of researcher allegiance on outcome. A single-item measure assessed researchers' reported attempts to control for therapist allegiance.RESULTS:Only 1 of 39 studies (3%) measured therapist treatment allegiance. Another 5 (13%) mentioned controlling for, without formally assessing, therapist allegiance. Most publications (67%) did not even mention therapist allegiance. In studies not controlling for therapist allegiance, researcher allegiance strongly influenced outcome, whereas studies reporting control for therapist allegiance showed no differential researcher allegiance. Researchers with cognitive-behavioral therapy allegiance described controlling for therapist allegiance less frequently than other researchers.CONCLUSIONS:The crossed therapist design is subject to bias due to differential psychotherapist allegiance. Worrisome results suggest that researchers strongly allied to a treatment may ignore therapist allegiance, potentially skewing outcomes. All clinical trials, and especially crossed therapist designs, should measure psychotherapist allegiance to evaluate this possible bias.

Psychotherapy for Substance Use Disorders – the importance of affects
- 2017
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Substance use disorder (SUD) is a serious disorder with severe consequences for the individual, the family and for society. Comorbidity is common in the SUD population and the diversity of the disorder calls for a multiplicity of treatment options.The overall aim of this thesis was to explore the role of affects in psychotherapy for SUD. Further aims were to investigate affect-focused therapeutic orientations, demonstrate the importance of common factors and evaluate a measure of affect phobia.In Study I a naturalistic design was employed to examine how the discrepancy between patients' expectations and experience of psychotherapy related to alliance in 41 patients: 24 in individual therapy and 17 in group. An additional analysis concerned whether different dimensions of role expectations predicted retention in psychotherapy. Study II was the first psychometric evaluation of the Affect phobia test – a test developed to screen the ability to experience, express and regulate emotions. Data were collected from two samples: A clinical sample of 82 patients with depression and/or anxiety participating in a randomized controlled trial of Internet-based affect-focused treatment, and a university student sample of 197 students. Data analysed included internal consistency, test-retest reliability, factor analysis and calculation of an empirical cut-off. Study III focused on the feasibility of individual 10 week Affect Phobia Therapy (APT) for patients diagnosed with mild to moderate alcohol use disorder (AUD) and problematic affective avoidance in a nonconcurrent multiple baseline design. Study IV comprised an evaluation of the feasibility and preliminary effectiveness of APT adapted to a structured group format for patients (n=22) with comorbid substance use disorder and ADHD with core features of affective avoidance/emotion dysregulation in an open design.In Study I an overall discrepancy between role expectations and experiences was significantly related to a lower level of therapeutic alliance in group therapy. This relationship was not found in individual therapy. Expectations prior to psychotherapy characterized by defensiveness correlated negatively with therapy retention, even when controlling for waiting time for therapy. In Study II the internal consistency for the total score on the Affect phobia test was satisfactory but it was not for the affective domains, Anger/Assertion, Sadness/Grief, and Attachment/Closeness. Test retest reliability was satisfactory. The exploratory factor analysis resulted in a six-factor solution and only moderately matched the test´s original affective domains. An empirical cut-off between the clinical and the university student sample were calculated and yielded a cut-off of 72 points. In Study III patients reported no adverse events due to the treatment and finished the whole study period. The patients had different trajectories of alcohol consumption and craving and the hypothesis that heavy episodic drinking would subside during the time in therapy did not hold true. In Study IV patients reported significant pre-to post changes in increased self-compassion and decreased affect phobia but no change in psychological distress or emotion dysregulation. Craving fluctuated throughout the study period and patients’ drinking pattern changed in the direction of more social drinking.Main conclusions are the following: The Affect Phobia Test is a useful screening instrument for detecting emotional difficulties related to psychological malfunction. APT in both group and individual format are feasible treatments for the SUD population and has the potential to broaden the treatment options for some patients with SUD. Investigating expectations and fears prior to therapy may be means to prevent attrition.

- Objectives To explore the associations between self-rated attachment style, psychological distress and substance use among substance use disorder (SUD) outpatients in psychological treatment.Design and Methods In this practice-based study, 108 outpatients were asked to fill in the Experiences in Close Relationships - Short form, the Clinical Outcomes in Routine Evaluation - Outcome Measure (CORE-OM), the Alcohol Use Disorders Identification Test (AUDIT), and the Drug Use Disorders Identification Test (DUDIT) at treatment start and end. Patients were given psychological treatments with a directive, reflective or supportive orientation.Results An insecure attachment style was more common among the SUD outpatients, compared to non-clinical groups. Patients with a fearful attachment style scored higher on psychological distress than patients with a secure attachment style. The associations between the attachment dimensions and psychological distress were stronger than those between attachment and SUD. Significantly more patients had a secure attachment style at treatment end.Conclusions This study shows significant relations between patients' attachment style and their initial psychological distress. The causal relationship between attachment style and psychological distress is, however, not clear and can likely go in both directions. The psychological treatment of patients with SUD contributed significantly to changes from insecure to secure attachment style.

- Background: More knowledge is needed about outcome of treatments in routine care for patients with substance use disorders (SUDs). These patients often suffer from psychological distress in addition to SUDs. Objectives: To evaluate the effects of community-based psychological treatment on SUD patients’ psychosocial problems, as well as on their substance use. Design: All patients who were referred or self-referred for psychological treatment to a social worker or a psychotherapist at three outpatient treatment centers for SUD patients were asked to participate in the study. Methods: Ratings at treatment start and end were obtained on Clinical Outcomes in Routine Evaluation - Outcome Measure (CORE-OM, n = 100), Alcohol Use Disorders Identification Test - Consumption (AUDIT-C, n = 49), and Drug Use Disorders Identification Test - Consumption (DUDIT-C, n = 27). Results: CORE-OM mean scores were significantly improved. In total 14% of the patients were recovered, 10% improved, and 5% deteriorated. Both AUDIT-C and DUDIT-C mean scores were significantly improved for patients with alcohol use and patients using illicit drugs, respectively. Conclusions: Routine psychological treatment had positive effects on psychological distress as well as on reduction of substance use. A substantial number of patients remained however unchanged, particularly regarding psychological distress. More studies with larger patient groups are needed to develop treatment for SUD patients in routine care.
