Tidskriftsartikel (refereegranskat)abstract
- The aim with the present paper is to illustrate the use of multivariate strategies (i.e. integration of different multivariate methods) with five examples, four from the pharmaceutical industry and one from environmental research.In the first part, two examples wherein hierarchical models are applied to quality control (QC) and process control are discussed. In the second part a more complex problem and a strategy for material discovery/development are presented wherein a combination of multivariate calibration, multivariate analysis and multivariate design is needed. In the third part, a process analytical/optimization problem is illustrated with a two-step process, demanding that different multivariate tools are combined in a sequential way so that a useful model can be established and the process can be understood. In the final part the usefulness of principal component analysis followed by soft independent modelling of class analogy is illustrated with an example from environmental process monitoring. The five examples from quite different areas show that the chemometric tools are even more powerful if used integrated. However, different strategies and combinations of the tools have to be applied, depending on the problem and the aim.

- PURPOSE: Childhood trauma in an important public health concern, and there is a need for brief and easily administered assessment tools. The Early Trauma Inventory (ETI) is one such instrument. The aim of this paper is to test the psychometric properties of the Swedish translation of the short, self-rated version (ETISR-SF), and to further validate the instrument.MATERIALS AND METHODS: In this cross-sectional study, 243 psychiatric patients from an open care unit in Sweden and 56 controls were recruited. Participants were interviewed and thereafter completed the ETISR-SF. Internal consistency was calculated using Cronbach's alpha, a confirmatory factor analysis (CFA) was performed and goodness-of-fit was determined. Intra Class Correlation (ICC) was used to calculate test-retest reliability. Discriminant validity between groups was gauged using the Mann-Whitney U-test.RESULTS: Cronbach's alpha varied between 0.55 and 0.76, with higher values in clinical samples than in controls. Of the four domains, general trauma showed a lower alpha than the other domains. The CFA confirmed the four-factor model previously seen and showed good to acceptable fit. The ICC value was 0.93, indicating good test-retest reliability. According to the Mann-Whitney U-test, the non-clinical sample differed significantly from the clinical sample, as did those with PTSD or borderline diagnosis from those without these diagnoses.CONCLUSIONS: The Swedish translation of the ETISR-SF was found to have similar psychometric properties as both the original version and translations. ETISR-SF scores could also distinguish between different diagnostic groups associated with various degrees of trauma, which supports its discriminant validity.

Tidskriftsartikel (refereegranskat)abstract
- BackgroundThe aim of this study was to investigate if temperament and experience of childhood trauma differed between young psychiatric patients with borderline personality disorder (BPD), bipolar disorder (BD) and attention-deficit/hyperactivity disorder (ADHD).MethodsDiagnoses were based on the Structured Clinical Interview for DSM Axis I and Axis II. Temperament was assessed by the Temperament and Character Inventory (TCI) and childhood trauma by the Early Trauma Inventory-Self Report-Short Form (ETI-SR-SF). Temperament and childhood trauma were compared between the BPD group (n = 19) and the non-BPD group (BD/ADHD) (n = 95). Interactions between trauma and temperament were evaluated using a logistic regression model with a BPD diagnosis as outcome variable.ResultsParticipants in the BPD group showed higher novelty seeking (NS) and harm avoidance (HA). Traumatic experiences in childhood were common but the BPD group differed very little from the others in this regard. The interaction between temperament and trauma had low explanatory power for a BPD diagnosis in this sample.ConclusionTemperament might be useful to distinguish BPD when symptoms of impulsivity and affective instability are evaluated in psychiatric patients. The results from the interaction analysis support the multifactorial background to BPD.

- Objectives: The Addiction Severity Index (ASI) is a standardized interview used to assess problems associated with substance use. Although widely used, the time required for the interview remains an obstacle to its acceptance in many clinical settings. We examined if a self-administered questionnaire based on the composite score (CS) items, the ASI Self-Report form (ASI-SR), offers a reliable alternative to the ASI in assessing current substance use and related problems.Methods:Participants were 59 treatment seeking individuals entering outpatient programs at the Addiction Psychiatric Clinic at Uppsala University Hospital who were assessed with Swedish versions of the ASI and ASI-SR. Agreement between the ASI interview's CS and ASI-SR's CS was evaluated on the individual basis by intraclass correlation analysis (ICC) and on group level with the Wilcoxon signed rank test. Reliability and internal consistency were evaluated using Cronbach's alpha.Results:For 6 out of 7 CS domains, the ICC for the ASI interview and ASI-SR were good to excellent. Internal consistency was acceptable for 6 out of 7 CS domains on the ASI interview and for 5 out of 7 CS domains on the ASI-SR.Conclusions:The present study suggests that the ASI-SR is a reliable alternative to the ASI interview for assessing current patient functioning and evaluation of problems related to alcohol and drug use.

Tidskriftsartikel (refereegranskat)abstract
- Background: Studies on both personality dimensions and cognition in schizophrenia are scarce. The objective of the present study was to examine personality traits and the relation to cognitive function and psychotic symptoms in a sample of patients with schizophrenia and healthy controls. Method: In total 23 patients with schizophrenia and 14 controls were assessed with the Karolinska Scales of Personality (KSP). A broad cognitive test programme was used, including the Wechsler Adult Intelligence Scales, the Finger-Tapping Test, the Trail Making Test, the Verbal Fluency Test, the Benton Visual Retention Test, the Wisconsin Card Sorting Test and Rey Auditory Verbal Learning Test . Results: Compared with controls, the patients exhibited prominent elevations on KSP scales measuring anxiety proneness and neuroticism (P = 0.000005-0.0001), on the Detachment scale (P < 0.00009) and lower value on the Socialization scale (P < 0.0002). The patients also scored higher on the Inhibition of Aggression, Suspicion, Guilt and Irritability scales (P = 0.002-0.03) while the remaining five scales did not differ between patients and controls. KSP anxiety-related scales correlated with the Positive and Negative Symptoms Scale (PANSS) general psychopathology subscale. Cognitive test results were uniformly lower in the patient group and correlated with PANSS negative symptoms subscale. There was no association between KSP scale scores and PANSS positive or negative symptoms. Conclusion: The patients revealed a highly discriminative KSP test profile with elevated scores in neuroticism- and psychoticism-related scales as compared to controls. Results support previous findings utilizing other personality inventories in patients with schizophrenia. Cognitive test performance correlated inversely with negative symptoms.

Forskningsöversikt (refereegranskat)abstract
- BACKGROUND: Instruments are frequently used in case finding, diagnosis and severity grading of major depression, but the evidence supporting their utility is weak.AIM: To systematically review the specificity and sensitivity of instruments used to diagnose and grade the severity of depression.METHODS: MEDLINE, PsycInfo, Embase and the Cochrane Library databases were searched until April 2014. Fifty studies fulfilled the inclusion criteria. Risk of bias was assessed with QUADAS. The average sensitivity and specificity of each instrument was estimated with hierarchical summary receiver operating characteristics analyses and the confidence in the estimates was evaluated using GRADE. Minimum acceptable sensitivity/specificity, with structured interview as the reference, was 80%/80% for structured interviews and 80%/70% for case-finding instruments. The minimum acceptable standard for severity measures was a correlation of 0.7 with DSM-IV classification.RESULTS: Twenty instruments were investigated. The average sensitivity/specificity was 85%/92% for the Structured Clinical Interview for DSM-IV-Axis-I Disorders (SCID-I), 95%/84% for the Mini International Neuropsychiatric Interview (MINI), < 70%/85% for the Primary Care Evaluation of Mental Disorders (PRIME-MD), 88%/78% for the Patient Health Questionnaire-9 (PHQ-9) with a cut-off score of 10, 69%/95% for PHQ-9 as a diagnostic algorithm and 70%/83% for the Hospital Anxiety and Depression Scale (HADS) with a cut-off score of 7. The confidence in the estimates for the other instruments was very low.CONCLUSIONS: Only the SCID-I, MINI and PHQ-9 with a cut-off score of 10 fulfilled the minimum criteria for sensitivity and specificity. The use of the PRIME-MD and HADS is not supported by current evidence.

- The objective of this study was to examine associations between childhood and adolescent psychiatric disorders and adult personality disorders in a group of former child psychiatric inpatients. One hundred and fifty-eight former inpatients with a mean age of 30.5 +/- 7.1 years at investigation had their childhood and adolescentAxis I disorders, obtained from their medical records, coded into DSM-IV diagnoses.Personality disorders in adulthood were assessed by means of the DSM-IV and ICD-10 Personality Questionnaire (DIP-Q). The predictive effects of child and adolescentAxis I disorders on adult personality disorders were examined with logistic regression analyses. The odds of adult schizoid, avoidant, dependent, borderline and schizotypalpersonality disorders increased by almost 10, five, four, three and three times, respectively, given a prior major depressive disorder. Those effects were independent of age, sex and other Axis I disorders. In addition, the odds of adult narcissistic and antisocial personality disorders increased by more than six and five times, respectively, given a prior disruptive disorder, and the odds of adult borderline, schizotypal, avoidant and paranoid personality disorders increased between two and three times given a prior substance-related disorder. The results illustrate an association between mental disorders in childhood and adolescence and adultpersonality disorders. Identification and successful treatment of childhood psychiatricdisorders may help to reduce the risk for subsequent development of an adultpersonality disorder.
