The WHO Adult ADHD self-report Scale used in a clinical sample of patients with overlapping symptoms - psychometric properties of and scoring methods for the Swedish translation.

BACKGROUND: The WHO Adult ADHD Self-report Scale (ASRSv1.1 and ASRS-S) is used for screening for attention-deficit/hyperactivity disorder (ADHD). The capacity of the Swedish version of the scale to discriminate ADHD from borderline personality disorder (BPD) and bipolar disorder (BP) has not been tested. AIM: Evaluate scoring methods, psychometric properties, and diagnostic accuracy of the Swedish versions of ASRSv1.1/ASRS-S in a group of patients with ADHD and/or BPD and/or BP. METHOD: A total of 151 young adult psychiatric patients diagnosed with ADHD, BPD and/or BD completed ASRSv1.1 and the Wender Utah Rating Scale (WURS) for ADHD symptoms, and the Sheehan Disability Scale (SDS) for functional impairment. ADHD diagnoses were assessed with the Schedule for Affective Disorders and Schizophrenia (K-SADS) interview. Both versions of the scale were analysed through dichotomised and non-dichotomised scoring for diagnostic accuracy analysis. RESULTS: The internal consistency for ASRSv1.1/ASRS-S was satisfactory with α 0.913 and 0.743, respectively. The two-factor structure of the ASRSv1.1 and the one factor structure of ASRS-S were supported by the confirmatory factor analyses. A strong positive correlation was found between ASRSv1.1 and WURS and a moderate level of correlation was found between ASRSv1.1 and SDS. The area under the curve for both scoring methods were excellent with an area under the curve (AUC) of 0.808 and 0.817, respectively. Optimal cut-off scores were in line with the original recommendations. CONCLUSION: The Swedish translation of ASRSv1.1/ASRS-S has psychometric properties comparable to other populations and the capacity to screen for ADHD in patients with overlapping symptoms.

Temperament, but not childhood trauma, distinguishes borderline personality disorder from bipolar disorder and ADHD.

BACKGROUND: The 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). METHODS: Diagnoses 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. RESULTS: Participants 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. CONCLUSION: Temperament 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.

Early Trauma Inventory Self-Report Short Form (ETISR-SF): validation of the Swedish translation in clinical and non-clinical samples.

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.

Wender Utah Rating Scale-25 (WURS-25): psychometric properties and diagnostic accuracy of the Swedish translation.

OBJECTIVE: The aim of this study was to examine the psychometric properties and diagnostic accuracy of the Swedish version of the Wender Utah Rating Scale (WURS) in psychiatric patients with similar symptoms but diagnosed with either attention deficit hyperactivity disorder (ADHD), bipolar disorder (BP), and/or borderline personality disorder (BPD). METHODS: A total of 121 patients from an outpatient psychiatric clinic for young adults (18-25 years) were diagnosed using the Structured Clinical Interview for DSM Axis I and Axis II (SCID-I and SCID-II), and ADHD was diagnosed using the Schedule for Affective Disorders and Schizophrenia for School-Age Children (K-SADS). WURS were filled in by the participants and compared with a diagnosis of ADHD according to K-SADS. RESULTS: Internal consistency of the WURS was 0.94. The principal component analysis resulted in a three-factor solution that accounted for 61.3% of the variance. The ADHD group had significantly higher mean scores compared to all other groups. The diagnostic accuracy of the WURS was examined using AUC and ROC analysis, and the optimal cut-off score was 39, with a sensitivity of 0.88 and specificity of 0.70, with AUC 0.87, 95% CI 0.80-0.94, PPV 0.59, and NPV 0.92. CONCLUSION: The psychometric properties of the Swedish WURS were good. For assessment of adult ADHD, in patients with symptoms of emotional instability, impulsivity, and attention problems but of different origins, a somewhat higher cut-off score than the originally suggested was preferable for identification of ADHD.

Young patients' views about provided psychiatric care.

BACKGROUND: Psychiatric illness is common among young adults, but there are only a few studies examining their views about the care they receive. There is a paradigm shift towards person-centred care and, therefore, a need for patients' perspectives in the development of clinical guidelines. AIM: The aim of this study was to examine the views about provided psychiatric care in a group of young adult psychiatric patients. METHOD: This study was part of a larger study. Patients between the ages of 19-29 years old (n = 127) diagnosed with bipolar disorder, borderline personality disorder, and/or attention deficit hyperactivity disorder were interviewed. Participants answered open-ended questions concerning their views about provided psychiatric care in six different areas. RESULT: The results were categorized into six themes: (1) Wish for better diagnostic assessments, (2) Dissatisfaction with treatment, (3) Inadequate information, (4) Lack of professional attitude, (5) Feeling abandoned, and (6) Satisfaction with care. CONCLUSION: Young psychiatric patients expressed a need for improvement of services that, if implemented, could make psychiatric care more person-centred.
