Abstract

This article describes psychometric testing of an Icelandic adaptation of the "Adult Reading History Questionnaire" (ARHQ), designed to detect a history of reading difficulties indicative of dyslexia. Tested in a large and diverse sample of 2,187 adults, the Icelandic adaptation demonstrated internal consistency reliability (Cronbach's alpha = 0.92) and test--retest reliability (r = 0.93). Validity was established by comparing scores of adults who as children received ICD-10 diagnoses of specific reading disorder (F81.0; n = 419) to those of adults defined as nondyslexics (n = 679). ROC curve analysis resulted in an area under the curve of 0.92 (95% CI = 0.90, 0.93, p < 0.001) and a cutoff score of 0.43 with sensitivity of 84.5% and specificity of 83.7%. An exploratory factor analysis (n = 2,187) suggested three subscales, Dyslexia Symptoms, Current Reading, and Memory, the mean scores of which differed significantly among diagnosed dyslexics, relatives of dyslexics, and population controls. Our results support the applicability of the ARHQ in Icelandic as a self-report screening tool for adult dyslexia in Iceland.

Abstract

We use polygenic risk scores (PRSs) for schizophrenia (SCZ) and bipolar disorder (BPD) to predict smoking, and addiction to nicotine, alcohol or drugs in individuals not diagnosed with psychotic disorders. Using PRSs for 144 609 subjects, including 10 036 individuals admitted for in‐patient addiction treatment and 35 754 smokers, we find that diagnoses of various substance use disorders and smoking associate strongly with PRSs for SCZ (P = 5.3 × 10−50–1.4 × 10−6) and BPD (P = 1.7 × 10−9–1.9 × 10−3), showing shared genetic etiology between psychosis and addiction. Using standardized scores for SCZ and BPD scaled to a unit increase doubling the risk of the corresponding disorder, the odds ratios for alcohol and substance use disorders range from 1.19 to 1.31 for the SCZ‐PRS, and from 1.07 to 1.29 for the BPD‐PRS. Furthermore, we show that as regular smoking becomes more stigmatized and less prevalent, these biological risk factors gain importance as determinants of the behavior., This study was funded in part by the National Institute on Drug Abuse (NIDA) (R01-DA017932 and R01-DA034076), and it received support from the European Community’s Seventh Framework Programme under the Marie Curie Industry Academia Partnership and Pathways (PsychDPC, GA 286213).

42. Medical Signs and Symptoms Associated with Disability, Pain, and Psychosocial Adjustment in Systemic Sclerosis

Author

Abstract

OBJECTIVE: To examine physician-assessed medical signs and patient-reported medical symptoms as correlates of 3 quality of life (QOL) outcomes in patients with systemic sclerosis (SSc): disability, pain, and psychosocial adjustment. METHODS: One hundred fourteen patients with SSc underwent a comprehensive clinical examination including determination of skin thickening [Modified Rodnan Skin Score (MRSS)]. Patients reported current symptoms and completed standardized questionnaires assessing disability and pain (Health Assessment Questionnaire) and psychosocial adjustment (Psychosocial Adjustment to Illness Scale). Regression analysis was used to examine physician-determined and patient-reported correlates of the 3 outcomes. RESULTS: MRSS was a significant correlate of all outcomes, although it explained only a small amount of the variance in psychosocial adjustment. Patient-reported postprandial bloating was the strongest correlate of psychosocial adjustment, explaining more than twice as much variance as MRSS. After accounting for MRSS, patient-reported dependent edema significantly correlated with all outcomes. For disability, significant correlates were physician-determined joint tenderness and number of tender points, and patient-reported joint pain on motion, joint contracture, extremity ulcers other than digital, and dyspnea. Patient-reported joint tenderness was significantly associated with pain. Regression analysis supported a model in which disability and pain mediated the relationship between MRSS and psychosocial adjustment. CONCLUSION: Skin score is strongly associated with disability and pain, but only weakly associated with psychosocial adjustment. Dependent edema has negative implications across quality-of-life outcomes. Disability and pain mediate the relationship between disease severity and psychosocial adjustment to disease. Assessment (including self-report of patient symptoms) of specific medical signs and symptoms may indicate SSc patients experiencing diminished QOL.
