“…These criteria were originally proposed by Clarke and Watson (1995) to ensure that: (1) the maximal amount of item level information is retained, (2) attenuated correlations were avoided, and (3) the measure has the ability to discriminate at different points on the underlying continuum. These criteria have been formalized by Lamping et al (2002) who proposed explicit cut-off values; these cut-off values are helpful in evaluating item performance, but we apply them descriptively rather than prescriptively, as the appropriateness of the values may differ depending on the nature of the instrument being developed. Criterion 1 related to interpretability; problematic interpretability was indicated by missing data of ≥ 10.0% for a given indicator.…”

Background: Two ‘sibling disorders’ have been proposed for the 11th version of the International Classification of Diseases (ICD-11): Posttraumatic Stress Disorder (PTSD) and Complex PTSD (CPTSD). To date, no research has attempted to identify the optimal symptom indicators for the ‘Disturbances in Self-Organization’ (DSO) symptom cluster. Objective: The aim of the current study was to assess the psychometric performance of scores of 16 potential DSO symptom indicators from the International Trauma Questionnaire (ITQ). Criteria relating to score variability and their ability to discriminate were employed. Method: Participants (N = 1839) were a nationally representative household sample of non-institutionalized adults currently residing in the US. Item scores from the ITQ were examined in relation to basic criteria associated with interpretability, variability, homogeneity, and association with functional impairment. The performance of the DSO symptoms was also assessed using 1- and 2-parameter item response theory (IRT) models. Results: The distribution of responses for all DSO indicators met the criteria associated with interpretability, variability, homogeneity, and association with functional impairment. The 1-parameter graded response model was considered the best model and indicated that each set of indictors performed very similarly. Conclusions: The ITQ contains 16 DSO symptom indicators and they perform well in measuring their respective symptom cluster. There was no evidence that particular indicators were ‘better’ than others, and it was concluded that the indicators are essentially interchangeable.

“…Standard psychometric methods were used to evaluate the Greek SAQOL-39g’s acceptability, test-retest reliability, internal consistency and construct validity (internal, convergent and discriminant) using a framework developed by Lamping et al [35]. For acceptability, criteria were: missing data <10%; floor/ceiling effects <80%, and skewness values between 1 and –1 for 75% of items (some skewness was expected but should not exceed 25% of items).…”

Background/Aims: Stroke and aphasia rehabilitation aims to improve people’s quality of life. Yet, scales for measuring health-related quality of life in stroke typically exclude people with aphasia. They are also primarily available in English. An exception is the 39-item generic version of the Stroke and Aphasia Quality of Life Scale (SAQOL-39g). This scale has been tested with people with aphasia; it has been adapted for use in many countries including Greece. The aim of this study was to examine the psychometric properties of the Greek SAQOL-39g. Methods: An interview-based psychometric study was carried out. Participants completed: receptive subtests of the Frenchay Aphasia Screening Test, the Greek SAQOL-39g, the 12-item General Health Questionnaire, the Frenchay Activities Index, the Montreal Cognitive Assessment and the Barthel Index. Results: 86 people took part; 26 provided test-retest reliability data. The Greek SAQOL-39g demonstrated excellent acceptability (minimal missing data; no floor/ceiling effects), test-retest reliability [intraclass correlation coefficient = 0.96 (overall scale), 0.83–0.99 (domains)] and internal consistency [Cronbach’s alpha = 0.96 (overall scale), 0.92–0.96 (domains)]. There was strong evidence for convergent [r = 0.53–0.80 (overall scale), 0.54–0.89 (domains)] and discriminant validity [r = 0.52 (overall scale), 0.04–0.48 (domains)]. Conclusion: The Greek SAQOL-39g is a valid and reliable scale. It is a promising measure for use in stroke and aphasia treatment prioritization, outcome measurement and service evaluation.

“…We have previously shown that patients largely fail to distinguish between sciatica bothersomeness and frequency [12]. The term ''bothersomeness'' has been increasingly utilized to measure symptoms, not only in sciatica and low back pain [10,17], but also in a broad spectrum of conditions such as prostatism [4], migraine [7], sinusitis [2] and pneumonia [22]. Therefore, in the present study, the SBI was chosen as the most appropriate instrument to assess how patients perceive their sciatica symptoms.…”

The bothersomeness of sciatica: patients’ self-report of paresthesia, weakness and leg pain

et al. 2009

The objective of the study was to investigate how patients with sciatica due to disc herniation rate the bothersomeness of paresthesia and weakness as compared to leg pain, and how these symptoms are associated with socio-demographic and clinical characteristics. A crosssectional study was conducted on 411 patients with clinical signs of radiculopathy. Items from the Sciatica Bothersomeness Index (0 = none to 6 = extremely) were used to establish values for paresthesia, weakness and leg pain. Associations with socio-demographic and clinical variables were analyzed by multiple linear regression. Mean scores (SD) were 4.5 (1.5) for leg pain, 3.4 (1.8) for paresthesia and 2.6 (2.0) for weakness. Women reported higher levels of bothersomeness for all three symptoms with mean scores approximately 10% higher than men. In the multivariate models, more severe symptoms were associated with lower physical function and higher emotional distress. Muscular paresis explained 19% of the variability in self-reported weakness, sensory findings explained 10% of the variability in paresthesia, and straight leg raising test explained 9% of the variability in leg pain. In addition to leg pain, paresthesia and weakness should be assessed when measuring symptom severity in sciatica.
