Abstract [en]

Attention Deficit Hyperactivity Disorder, ADHD, occurs in about 5 % of the adult population and includes cardinal symptoms of hyperactivity, inattention, and impulsivity that may be difficult to identify with clinical routine methods. Continuous performance tests are objective measures of inattention and impulsivity that, combined with objective measures of motor activity, facilitate identification of ADHD among adults. The aim of the present study was to examine sensitivity, specificity and a composite measure of ADHD using objective measures of the ADHD-cardinal symptoms in adult participants with ADHD and non-ADHD normative participants.

Cardinal symptoms were measured in 55 participants having ADHD, 202 non-ADHD normative participants, as well as 84 ADHD normative participants using the Quantified Behavior Test Plus, QbTest-Plus. This test measures inattention and impulsivity with a continuous performance test and hyperactivity with a motion tracking system.

A predictive variable for detection of ADHD called Prediction of ADHD, PADHD, yielded 86 % sensitivity and 83 % specificity. A composite measure of ADHD cardinal symptoms was developed with a Weighed Core Symptoms scale, WCS, that indicates the total amount of ADHD symptoms on a numeric scale from 0 to 100.

The total amount of ADHD symptoms was measured on a scale and predicted with the categorical variable in a majority of the cases in the present study. Further studies are needed in order to confirm the results with regard to additional clinical and normative samples. Careful consideration of potential gender and diagnostic subtype differences are noteworthy aspects for future examinations of the new instruments.

Abstract [en]

PURPOSE:

In this study, the individuals with psychotic disorders' daily life function was investigated on six dimensions considering their relations to family burden. Functional ratings carried out by relatives and staff were also compared.

METHODS:

Totally 88 relatives, to as many individuals diagnosed with a psychotic disorder, participated in this study. Relatives were to rate their own perceived burden and their ill relatives' physical functioning, personal care skills, interpersonal relationships, social acceptability, activities, and work skills. The outpatient staff, in all 24 case managers also rated the patients' functional level on the same assessment tool as did the relatives.

RESULTS:

Most dimensions of patients' everyday functioning were highly correlated to relatives' burden. The two functional dimensions "interpersonal relationships" and "activities" were best at classifying burden when rated by relatives. Also, comparing independent functional ratings by relatives and staff showed that despite great agreements on most dimensions, they differed significantly on "social acceptability" where relatives rated the function to be poorer and "activities" where relatives rated the function to be better.

CONCLUSIONS:

Relatives, who perceive individuals with a psychotic disorder to be limited in their ability to interpersonal relationships and limited in their ability to activate in everyday life, are more likely to perceive a higher burden. Even though staff and relatives mainly agree on the patients' functional ability, they often differ in ratings regarding patients' social acceptability and ability to activate in everyday life. This should be worth considering in clinical practice as well as in future research.

Abstract [en]

The purpose of this project was to do a qualitative study of an integrated and flexible ACT model, the Resource Group Assertive Community Treatment (RACT), as seen from the perspective of case managers in training. The resource group normally consists of the client, the case manager and other available personnel in the medical and support areas, as well as family members. Nineteen theses were randomly chosen from a set of 80 theses written by a group of Swedish trainee case managers. The exams were conducted as case studies and concerned 19 clients with psychotic problems, 11 men and 8 women. “The Empirical Phenomenological Psychological Method” was used in the analysis, which generated five overarching themes: (a) the RACT program; (b) the resource group; (c) the empowerment of the client; (d) progress in treatment; and (e) the case manager. These together constituted a “therapeutic circle,” in which methods and tools used within the RACT made it possible for the resource group to empower the clients who, as a result, experienced progress with treatment, during which the case manager was the unifying and connecting link.

Abstract [en]

This study investigated whether “re-usable” soldiers, that is, those who performed well during operations (Military capacity), and were able to readjust post-deployment (Civil adjustment), could be identified pre-deployment. Participants were 364 UN peacekeeping soldiers. Three hypotheses were posed: (a) the selection system for conscripts cannot identify soldiers with low Military capacity, (b) the selection system for conscripts cannot identify soldiers with poor Civil adjustment after deployment, and (c) the two aspects of “re-usability” (Military Capacity and Civil Adjustment) would be intertwined. Results showed that the selection system for conscripts was unable to identify soldiers’ Military Capacity and Civil Adjustment. Results also showed that these two aspects were unrelated, and did not interact. Indications on possible consequences, and improvements were discussed.

Abstract [en]

Background: The present study evaluated two psychometric instruments derived from the objective measurement of adult ADHD using the Quantified Behavior Test Plus. The instruments were examined in ADHD versus a clinical group with overlapping symptoms including borderline personality disorder and bipolar II disorder, and another clinical group with participants assessed for but disconfirmed a diagnosis of ADHD as well as adult normative participants.

Methods: The Quantified Behavior Test Plus includes Continuous Performance Testing and a Motion Tracking System with parameters related to attention and activity operationalized as the cardinal symptoms of ADHD and then summarized into a Weighed Core Symptoms scale with ten cut-points ranging from 0 to 100. A categorical predictor variable called Prediction of ADHD was used to examine the levels of sensitivity and specificity for the Quantified Behavior Test Plus with regard to ADHD.

Results: The Weighed Core Symptoms scale separated ADHD and normative participants from each other as well as from the two clinical reference groups. The scale reported highest levels of core symptoms in the ADHD group and the lowest level of core symptoms in the normative group. Analyses with Prediction of ADHD yielded 85 % specificity for the normative group, 87 % sensitivity for the ADHD group, 36 % sensitivity for the bipolar II and borderline group and 41 % sensitivity for the group with a disconfirmed diagnosis of ADHD.

Conclusions: The Weighed Core Symptoms scale facilitated objective assessment of adult ADHD insofar that the ADHD group presented more core symptoms than the other two clinical groups and the normative group. Sensitivity for the Quantified Behavior Test Plus was lower in complex clinical groups with Bipolar II disorder, Borderline disorder and in patients with a disconfirmed diagnosis of ADHD. The psychometric instruments may be further evaluated with regard to well-documented and effective treatment programs for ADHD core symptoms.

Abstract [en]

OBJECTIVE: The relationships between subjectivesatisfaction, distress and quality of life for severelymental ill patients with different functional levels andgender was investigated in a multi-center cohort,using a balanced mix of subjective and clinician ratingsin an outcome-informed model for a clinicalmanagement based on shared decision making, "TheQuality Star". METHODS: Naturalistic data for 2552persons, mainly with schizophrenia diagnoses, in longtermtreatment and rehabilitation, were analyzed in across-sectional study. RESULTS: With increasingSocial Function, rated with the split-GAF Disability/Functioning scale, the better were patients' Satisfaction,subjective Quality of life and Perceived GlobalDistress. Women were more satisfied with thecare but also more distressed. CONCLUSION: Mainfindings were in line with other studies. However, thegender differences are in line with some, but not withother, studies. This poses questions how patient factors,instrument constructs, and treatment, especiallyshared decision making, influence subjective reports.

Abstract [en]

Background: Self-care treatments with bed of nails or spike mats have gained increased popularity world-wide; advertised as a method for pain reduction and wellbeing. Scientific studies regarding effects are still lacking. The aim of the present study was to investigate if daily relaxation on a spike mat for three weeks could induce beneficial effects.Design and methods: Participants were 36 individuals suffering from muscle tension pains in their back or/and neck. They were randomly assigned to a control group or an experimental group, who were treated with 15 minutes daily rest during three weeks on the spike mat.Results: Significant reduced experienced worst pain intensity was found. There were no effects on normal pain intensity, optimism, anxiety, depression, stress, energy, or sleep quality. Conclusion: The participants appreciated the treatment, but their enthusiastic verbal reports of experienced beneficial effects could not be verified in the statistical analyses. The reduction of worst pain may be explained by the gate-control theory, where competing stimuli applied over the affected area produce a pain reduction. It can also be an effect of placebo or the relaxation. More research on relaxation on a spike mat is needed before its possible effects can be confirmed. No negative effects were found in the present study, but it has to be remembered no studies investigating risks for treatment on spike mats exist.
