AbstractTo develop the Symptom Questionnaire for Visual Dysfunctions (SQVD) and to perform a psychometric analysis using Rasch method to obtain an instrument which allows to detect the presence and frequency of visual symptoms related to any visual dysfunction. A pilot version of 33 items was carried out on a sample of 125 patients from an optometric clinic. Rasch model (using Andrich Rating Scale Model) was applied to investigate the category probability curves and Andrich thresholds, infit and outfit mean square, local dependency using Yen’s Q3 statistic, Differential item functioning (DIF) for gender and presbyopia, person and item reliability, unidimensionality, targeting and ordinal to interval conversion table. Category probability curves suggested to collapse a response category. Rasch analysis reduced the questionnaire from 33 to 14 items. The final SQVD showed that 14 items fit to the model without local dependency and no significant DIF for gender and presbyopia. Person reliability was satisfactory (0.81). The first contrast of the residual was 1.908 eigenvalue, showing unidimensionality and targeting was − 1.59 logits. In general, the SQVD is a well-structured tool which shows that data adequately fit the Rasch model, with adequate psychometric properties, making it a reliable and valid instrument to measure visual symptoms.

And Control

Attachment theory has proposed that early separation anxiety is a risk factor for adult anxiety disorder, with the recent focus being particularly on panic disorder. The results of empirical studies examining this link are, however, contradictory, possibly because of inconsistencies across studies in measuring memories of early separation anxiety. In the present study, a psychometrically sound measure, the Separation Anxiety Symptom Inventory (SASI) was used to compare memories of such early symptoms in panic disorder (including those with mild phobic-avoidance), generalised anxiety disorder and control subjects. Anxiety patients as a group returned higher SASI scores (p<0.001) with a non-significant trend for panic disorder patients to score higher than those with generalised anxiety. These results suggest that early separation anxiety may be a harbinger of adult anxiety and that risk of panic disorder may be higher in the most severely affected youngsters. As a risk factor, early separation anxiety does not however appear to be uniquely related to adult panic disorder.

Separation anxiety continues to be implicated as an early risk factor to adult emotional disorder but recent research findings are somewhat contradictory. Inconsistencies in approaches to measuring memories of early separation anxiety may have contributed to this lack of clarity. We report the development of a brief self-report instrument, the Separation Anxiety Symptom Inventory (SASI), which was designed to overcome some of these deficiencies in measurement. The SASI was shown to have a coherent factorial structure, high internal consistency (Cronbach's Alpha>.80) and test-retest reliability over an average of 24 months (Intraclass Correlation Coefficient =. 89), with serial scores not being affected by changes in contemporaneous anxiety levels. Some index of the validity of the measure was achieved by (a) comparing SASI scores of index twins with descriptors of their “insecure’ behaviours in early life provided by corresponding co-twins; (b) comparing SASI scores with retrospective DSM III-R diagnoses of early anxiety disorders obtained by structured interviews; and (c) examining SASI scores in subjects with histories of school refusal. The SASI provides a useful standardised measure which will aid in the further testing of the separation anxiety hypothesis of adult emotional disorder.

Objective: The tripartite model of anxiety and depression has been proposed as a representation of the structure of anxiety and depression symptoms. The Mood and Anxiety Symptom Questionnaire (MASQ) has been put forwards as a valid measure of the tripartite model of anxiety and depression symptoms. This research set out to examine the factor structure of anxiety and depression symptoms in a clinical sample to assess the MASQ's validity for use in this population. Method: The present study uses confirmatory factor analytic methods to examine the psychometric properties of the MASQ in 470 outpatients with anxiety and mood disorder. Results: The results showed that none of the previously reported two-factor, three-factor or five-factor models adequately fit the data, irrespective of whether items or subscales were used as the unit of analysis. Conclusion: It was concluded that the factor structure of the MASQ in a mixed anxiety/ depression clinical sample does not support a structure consistent with the tripartite model. This suggests that researchers using the MASQ with anxious/depressed individuals should be mindful of the instrument's psychometric limitations.
