- 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.

- Background: The schedule for affective disorders and schizophrenia for school-age children (K-SADS) is one of the most commonly used standardized diagnostic interviews in child and adolescent psychiatry. Validity studies are scarce, and limited to concurrent validity with other measures and clinical diagnoses.Aims: To evaluate the K-SADS interview in an outpatient child and adolescent psychiatry (CAP) setting with a Longitudinal Expert All Data (LEAD) procedure.Methods: CAP residents performed a K-SADS-PL interview with the revised 2009 version containing the new PDD section on 239 clinically referred outpatients of 6-17 years old and their parent(s). A consensus LEAD diagnosis by two senior clinicians 1.2 (SD=0.6) years later was based on clinical records including the K-SADS and subsequent information from further assessments, information from teachers and other informants, outcome of treatment, and at least three visits after the K-SADS.Results: Predictive validity for K-SADS vs LEAD diagnoses were good-to-excellent for broader categories of anxiety disorders (=0.94), depressive (=0.91), behavioural (=0.91) and tic (=0.81) disorders, good for ADHD (=0.80), and good-to-moderate for autism spectrum disorders (=0.62). Bipolar, psychotic, and eating disorders were too few to be analysed.Conclusion: The K-SADS diagnoses elicited from an interview with the child and one from parents on one occasion have an excellent validity for most major child psychiatric disorders. ADHD can be reliably diagnosed at one visit, but clinicians need to stay alert for possible undiagnosed ADHD. Diagnosing autism with K-SADS-PL 2009 version at one visit is not advisable.

Tidskriftsartikel (refereegranskat)abstract
- Background: Apathy, a prevalent and clinically relevant symptom in neurodegenerative disease, is often evaluated by the instrument Apathy Evaluation Scale (AES). However, this instrument has not been translated into Swedish, halting clinical and research efforts. Furthermore, previous studies lack analyses of some basic properties, such as the legitimacy of a total score, or have analysed dimensionality by questionable methods.Aim: To translate and psychometrically evaluate a Swedish version of the AES.Method: The AES was translated, and its psychometric properties were tested in the Swedish BioFINDER study, including cognitively well elderly, and subjects with mild cognitive or parkinsonian symptoms. Psychometric analyses were conducted according to classical test theory (CTT) and aimed to resemble those performed in the English original study by Marin etal. in 1991. Dimensionality was additionally analysed on a matrix of polychoric correlations and parallel analyses.Results: Data indicate that the Swedish AES performs satisfactorily regarding data completeness, scaling assumptions, targeting, and reliability. Principal component analyses (with parallel analysis) of polychoric correlation matrices identified a single component. Convergent and discriminative validity correlations accorded with a priori expectations.Conclusions: The study provides initial support that this Swedish AES performs similarly to the English original, and exhibits acceptable psychometric properties according to CTT, including supported unidimensionality, and may be adopted for use in clinical and research settings.

- The presence of comorbid conditions associated with paediatric obsessive-compulsive disorder (OCD) is reported to range from 50 to 80% and to have an impact on treatment outcome. Accurate identification of comorbid psychiatric disorders is necessary in order to provide personalised care. Reliable and valid diagnostic interviews are essential in the process of establishing the correct diagnoses. The objective of this study was to evaluate the convergent and divergent validity of four diagnose categories generated by the Schedule for Affective Disorders and Schizophrenia for School-Age Children - Present and Lifetime Version (K-SADS-PL). The diagnose categories were: anxiety, depression, attention deficit hyperactivity disorder (ADHD), and oppositional defiant disorder (ODD). The K-SADS-PL was applied in a clinical sample of youth aged 7-17 years (N = 269), who were participants in the Nordic long-term OCD-treatment study (NordLOTS). Youth and parents completed measures to evaluate symptoms of anxiety, depression, ADHD, and ODD. Convergent and divergent validity of K-SADS-PL anxiety diagnosis was supported based on both anxiety self- and parent-reports. Similarly, support was found for convergent and divergent validity of ADHD and ODD diagnoses. For depressive disorder, support for convergent validity was found based on the depression self-report. Support for divergent validity of depression was found based on both the depression self- and parent-reports. Results of the present study suggest that the K-SADS-PL generates valid diagnoses of comorbid anxiety disorders, depression disorders, ODD, and ADHD in children and adolescents with OCD.

- Background: Forensic psychiatric patients present a challenge as they manifest severe mental disorders together with criminal behaviour. There are well-known risk factors for criminal behaviour in the general population, yet knowledge of what predicts reconviction in the Swedish forensic population in the long-term perspective is still insufficient. Aims: The study aims to (1) describe background and clinical characteristics of forensic psychiatric patients in a 10-year follow-up, (2) analyse risk factors associated with recidivism, and (3) test the predictive validity of risk factors for general and violent criminality. Methods: Detailed information on all offenders from the Malmö University Hospital catchment area sentenced to forensic psychiatric in-patient treatment from 1999–2005 (n = 125) was collected. Court decisions were collected up until the end of 2008 (median follow-up time = 6.2 years, range = 0.6–9.7 years). Results: Relapse in general crime (n = 30) was predicted by low educational attainment, mental disorder in a first degree relative, and low age at first sentenced crime. Relapse in violent crime (n = 16) was predicted by low educational attainment and low GAF scores. Patients with a restriction order were less likely to relapse in both crime categories. Conclusions: Signs of childhood adversities together with early debut in criminality appeared as important risk factors for general and violent recidivism. Forensic psychiatric treatment combined with a restriction order was demonstrated as a protective factor against recidivism, suggesting that the risk of recidivism is strongly related to the level of supervision. Although the low number of recidivism cases is highly desirable, it unfortunately reduces the power of the analyses in this paper.

- Aims: This study describes changes in alcohol habits in age and gender strata among the Swedish general population during the 21-year period following the Swedish EU membership in 1995.Methods: The Alcohol Use Disorders Identification Test (AUDIT) was distributed as a postal questionnaire to randomly selected cross-sectional samples every fourth year, starting in 1997.Results: Six samples were included in this study. A comparison between 2014 and 2018 showed a tendency to decreasing average total AUDIT scores, particularly among men and in the youngest age group (Cohen’s d = 0.28).Conclusion: The results should be understood in the context of declining response rates in this type of survey.

- Aims: The Alcohol Use Disorders Identification Test (AUDIT) is a well-established and widely used screening instrument. It has been shown that AUDIT has good criterion validity in relation to alcohol abuse and dependence according to DSM-IV, but it has not yet been validated following the introduction of the DSM-5 diagnostic system. The aim of this study was to evaluate concurrent validity for the AUDIT in relation to self-reported DSM-5 severity levels for Alcohol Use Disorder (AUD) in a Swedish general population sample.Methods: A postal questionnaire, containing the AUDIT and the 13-item brief DSM-5 AUD diagnostic assessment screener, was sent to a random sample of 1,500 persons drawn from the Swedish population, aged between 17 and 80 years and having a public residence address in Sweden. To evaluate the concurrent validity of AUDIT in relation to DSM-5 severity criteria for AUD, a Receiver Operating Characteristics (ROC) curve analysis was conducted.Results: Area under the curve (AUROC) showed excellent differentiation between AUD or not, mild (.93), moderate (.92) and severe (.99). Higher individual AUDIT scores were associated with more severe levels of AUD according to the DSM-5 screener. The optimal cutoff scores approximate earlier research on the DSM-IV and were identified as 5, 7 and 13 points, respectively, for mild, moderate and severe AUD.Conclusions: Our findings indicate that AUDIT is a valid screener for detecting concurrent AUD at three severity levels in the Swedish general population.

- AIM: The aim of the study was to explore the psychometric properties of the Inventory of Interpersonal Problems (IIP-64) and to compare levels of interpersonal distress in Swedish female outpatients with anorexia nervosa or bulimia nervosa with age- and gender-matched controls.METHODS: Totally, 401 participants were included; anorexia nervosa (n = 74), bulimia nervosa (n = 85) and controls (n = 242). All participants completed the IIP-64. The eating disorder (ED) patients also filled out the Eating Disorder Inventory-2/3 (EDI).RESULTS: Internal consistency of IIP-64 was acceptable to high. Principal component analyses with varimax rotation of the IIP-64 subscales confirmed the circumplex structure with two underlying orthogonal dimensions; affiliation and dominance. Significant correlations between EDI-3 composite scales ineffectiveness and interpersonal problems and IIP-64 were found. ED patients reported higher levels of interpersonal distress than controls on all but one subscale (intrusive/needy).CONCLUSIONS: IIP-64 can be considered to have acceptable to good reliability and validity in a Swedish ED sample. IIP-64 can be a useful complement in assessment of interpersonal problems in ED.

Tidskriftsartikel (refereegranskat)abstract
- Background: In clinical practice, the differential diagnosis of Asperger syndrome (AS) versus schizophrenia can be a challenge. Some self-report instruments-such as the Autism-spectrum Quotient (AQ)-have been portrayed as proxies for the diagnosis of AS. However, it has not been demonstrated to what extent autistic traits-as measured by the AQ-separate AS from schizophrenia. Aim: To examine the AS-schizophrenia discriminating ability of the AQ. Method: The AQ is a 50-item self-administered questionnaire (with score range 0-50) for measuring "autistic traits" in adults. Here, it was completed by 136 individuals: 36 with schizophrenic psychosis, 51 with AS and 49 non-clinical comparison cases. A receiver operating characteristic (ROC) analysis for the total AQ score was performed to examine the discriminating power of the instrument. Result: Both individuals with schizophrenia and individuals with AS scored significantly higher on AQ than the non-clinical group. The mean total AQ score (± standard deviation) of the AS group (26.7 ± 8.9; range 9-44) was significantly higher than that of the schizophrenia group (22.7 ± 6.2; range 10-35) (P = 0.041). However, when using the full Likert scale for scoring, the difference did not reach significance. In the ROC analysis of total AQ scores for AS versus schizophrenia, the area under the curve (AUC) was 0.65 (P = 0.02). Conclusion: Although mean AQ scores separated AS and schizophrenia at a group comparison level, significant overlap of AQ scores across the two diagnostic groups clearly reduces the discriminating power of the AQ in the separation of schizophrenia from AS.
