The Symptom Checklist: Frequency and Severity Scale (SCL) is a symptom-specific questionnaire that measures the patient’s perception of the frequency and severity of arrhythmia-related symptoms. Worldwide, the SCL is one of the most used symptom-specific questionnaires for this purpose. Until now, there has not been a valid Swedish translation of the SCL. This study aimed to translate the SCL into Swedish and test the face, content and construct validity of the translated version. The questionnaire was translated using the WHO’s recommendations for translation. Using the ‘think aloud method’, we gathered data from 12 patients regarding the intelligibility of the questions. Using exploratory factor analysis (EFA), we evaluated the face validity, construct validity and internal consistency properties of the questionnaire. The study included 646 patients with different types of supraventricular tachycardia, atrial fibrillation (AF) atrial flutter (AFL), atrioventricular reentrant tachycardia (AVRT), atrioventricular nodal reentrant tachycardia (AVNRT), and ectopic atrial tachycardia (EAT). Translation and face validity were found to be acceptable. Construct validity evaluated using EFA and principal component analysis with varimax rotation identified four factors with eigenvalues greater than 1 and factor loading equal to or greater than 0.364, accounting for 58% and 53% of the variance in the frequency scale and the severity scale, respectively. Reliability evaluation revealed high internal consistency. For both the frequency and severity scale, the Cronbach’s alpha coefficient was 0.88. Our results show evidence that the Swedish version of the SCL has good psychometric properties according to face and construct validity and internal consistency for patients with AF, AFL, AVRT, AVNRT and EAT, and is reproducible and valid.

AbstractObjectiveTo evaluate the psychometric properties of the HIV Disability Questionnaire (HDQ) among adults living with HIV in London, United Kingdom (UK).MethodsThis is a cross-sectional measurement study. We recruited and administered the self-reported HDQ, seven criterion measures, and a demographic questionnaire with adults living with HIV accessing HIV care. We determined median and interquartile ranges (IQR) for disability presence, severity and episodic scores (range 0-100). We calculated Cronbach’s alpha (α) Kuder-Richardson-20 (KR-20) statistics for disability and episodic scores respectively (internal consistency reliability), smallest detectable change (SDC) for each HDQ severity item and domain (precision), and tested 36 a priori hypotheses assessing correlations between HDQ and criterion scores (construct validity).ResultsOf N=243 participants, all were male, median age 40 years, 94% currently taking antiretroviral therapy, and 22% living with ≥2 concurrent health conditions. Median HDQ domain scores ranged from 0 (IQR: 0,7) (difficulties with day-to-day activities domain) to 27 (IQR: 14, 41) (uncertainty domain). Cronbach’s alpha for the HDQ severity scale ranged from 0.85 (95% Confidence Interval (CI): 0.80-0.90) in the cognitive domain to 0.93 (95%CI: 0.91-0.94) in the mental-emotional domain. The KR-20 statistic for the HDQ episodic scale ranged from 0.74 (95%CI: 0.66-0.83) in the cognitive domain to 0.91 (95%CI: 0.89-0.94) in the uncertainty domain. SDC ranged from 7.3-15.0 points on the HDQ severity scale for difficulties with day-to-day activities and cognitive symptoms domains, respectively. The majority of the construct validity hypotheses (n=30/36, 83%) were confirmed.ConclusionsThe HDQ possesses internal consistency reliability and construct validity with varied precision when administered to males living with HIV in London, UK. Clinicians and researchers may use the HDQ to measure the nature and extent of disability experienced by PLHIV in the UK, and to inform HIV service provision to address the health-related challenges among PLHIV.

Background: There are presently no validated scales to adequately measure the stigma of suicide in the community. The Stigma of Suicide Scale (SOSS) is a new scale containing 58 descriptors of a “typical” person who completes suicide. Aims: To validate the SOSS as a tool for assessing stigma toward suicide, to examine the scale’s factor structure, and to assess correlates of stigmatizing attitudes. Method: In March 2010, 676 staff and students at the Australian National University completed the scale in an online survey. The construct validity of the SOSS was assessed by comparing its factors with factors extracted from the Suicide Opinion Questionnaire (SOQ). Results: Three factors were identified: stigma, isolation/depression, and glorification/normalization. Each factor had high internal consistency and strong concurrent validity with the Suicide Opinion Questionnaire. More than 25% of respondents agreed that people who suicided were “weak,” “reckless,” or “selfish.” Respondents who were female, who had a psychology degree, or who spoke only English at home were less stigmatizing. A 16-item version of the scale also demonstrated robust psychometric properties. Conclusions: The SOSS is the first attitudes scale designed to directly measure the stigma of suicide in the community. Results suggest that psychoeducation may successfully reduce stigma.

Poor Sleep Quality

Sleep quality is an important clinical construct since it is increasingly common for people to complain about poor sleep quality and its impact on daytime functioning. Moreover, poor sleep quality can be an important symptom of many sleep and medical disorders. However, objective measures of sleep quality, such as polysomnography, are not readily available to most clinicians in their daily routine, and are expensive, time-consuming, and impractical for epidemiological and research studies., Several self-report questionnaires have, however, been developed. The present review aims to address their psychometric properties, construct validity, and factorial structure while presenting, comparing, and discussing the measurement properties of these sleep quality questionnaires. A systematic literature search, from 2008 to 2020, was performed using the electronic databases PubMed and Scopus, with predefined search terms. In total, 49 articles were analyzed from the 5734 articles found. The psychometric properties and factor structure of the following are reported: Pittsburgh Sleep Quality Index (PSQI), Athens Insomnia Scale (AIS), Insomnia Severity Index (ISI), Mini-Sleep Questionnaire (MSQ), Jenkins Sleep Scale (JSS), Leeds Sleep Evaluation Questionnaire (LSEQ), SLEEP-50 Questionnaire, and Epworth Sleepiness Scale (ESS). As the most frequently used subjective measurement of sleep quality, the PSQI reported good internal reliability and validity; however, different factorial structures were found in a variety of samples, casting doubt on the usefulness of total score in detecting poor and good sleepers. The sleep disorder scales (AIS, ISI, MSQ, JSS, LSEQ and SLEEP-50) reported good psychometric properties; nevertheless, AIS and ISI reported a variety of factorial models whereas LSEQ and SLEEP-50 appeared to be less useful for epidemiological and research settings due to the length of the questionnaires and their scoring. The MSQ and JSS seemed to be inexpensive and easy to administer, complete, and score, but further validation studies are needed. Finally, the ESS had good internal consistency and construct validity, while the main challenges were in its factorial structure, known-group difference and estimation of reliable cut-offs. Overall, the self-report questionnaires assessing sleep quality from different perspectives have good psychometric properties, with high internal consistency and test-retest reliability, as well as convergent/divergent validity with sleep, psychological, and socio-demographic variables. However, a clear definition of the factor model underlying the tools is recommended and reliable cut-off values should be indicated in order for clinicians to discriminate poor and good sleepers.

The purpose of this study was to create a valid and reliable instrument to evaluate theory-basedbeliefs towards physical activity among clergy members. Data were collected from 174 clergy that par-ticipated in a 15-item online and paper-based survey. Psychometric properties of the instrument includedconfirmatory factor analysis (construct validity), and cronbach’s alpha (internal consistency reliability).In addition, the stability (test-retest reliability) of each subscale was evaluated with a sub-sample of 30participants. Results show the instrument was both valid and reliable, and will be useful in future studiestargeting this population. Future implications are discussed.

e24027 Background: The ongoing two-part phase 2/3 RESILIENT study (NCT03088813) is investigating the efficacy and safety of liposomal irinotecan monotherapy in patients with SCLC who have progressed on or after first line platinum-based chemotherapy. This exploratory analysis from RESILIENT part 1 was conducted to confirm the psychometric properties of established PRO instruments that had not previously been validated in patients with SCLC. Methods: Patients completed the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ) Core 30 (C30) and the EORTC QLQ Lung Cancer 13 (LC13) before treatment assignment (baseline), every 6 weeks thereafter, at treatment discontinuation and at the 30-day follow-up visit. Psychometric methods included descriptive statistics (items and scales), correlations (item-to-item and item-to-total), internal consistency (Cronbach’s α), test-retest reliability (intraclass correlation coefficient [ICC], two-way random effects model), construct validity and sensitivity to change. The analysis included patients who received at least one dose of study drug and completed at least one PRO assessment. Results: Thirty patients were enrolled in RESILIENT part 1 and included in the analysis. At baseline, 68% of patients reported ‘not severe’ or ‘mild’ symptoms. Floor effects (i.e. more than 25% of responses of ‘not at all’) were observed for several of the functioning/impact and symptom scales of the EORTC QLQ C30 and LC13. Moderate to strong correlations were found among most questionnaire items within their respective scales. Acceptable evidence for internal consistency and good test-retest reliability were observed. Selected results for the EORTC QLQ LC13, including dyspnea scales, are shown in the Table. The magnitude of correlations among PRO instruments supported evidence for convergent validity in this sample. Conclusions: In RESILIENT part 1, patients experienced low and tolerable symptoms at enrollment, limiting the potential for further improvement. Overall, these PRO instruments had acceptable psychometric properties (e.g. construct validity, reliability and ability to detect change) in this sample. However, these analyses should be repeated in a larger sample using data from RESILIENT part 2. Clinical trial information: NCT03088813. [Table: see text]

Our purpose in this study was to develop a scale to measure preference for online social interaction (POSI). The psychometric properties of the POSI Scale were tested with 2 separate samples of Chinese teenagers (age 13–18 years). The responses of the first group (n = 352) were used to explore the factor structure of the scale. The responses of the second group (n = 593) were used to test construct validity and consistency reliability of the POSI Scale. The results indicated that (a) the POSI Scale consists of three dimensions: online social interaction frequency, online social interaction propensity, and perception of superiority of online social interaction compared to face-to-face social interaction; and (b) the POSI Scale has good structural validity and internal consistency and reliability, and is a reliable and valid instrument for measurement of adolescents' preference for online social interaction, especially in the context of Chinese teenagers.

Objective: To determine face, content, and construct validity, and internal consistency of ROL scale. Methods and Findings: A three-phase study was conducted. First, content analysis of the scale was carried out consulting 10 professional experts. Then, face validity was analyzed with 60 caregivers. Finally, construct validity was evaluated by performing an exploratory factor analysis (EFA) with 110 participants. Internal consistency of ROL scale was also assessed. Face validity of ROL scale reached a high acceptance index in three dimensions: role performance (0.97), role organization (0.98), and response to the role (0.98). Content validity showed coherence, clarity, and relevance of the scale. From factor analysis, three components emerged and were grouped in the same manner for varimax, quartimax, and equimax rotations. Cronbach's alpha was 0.816, which is an acceptable overall value. Conclusion: ROL scale makes objective the concept of role taking in family caregivers of people with chronic disease. It demonstrated to have acceptable reliability, and construct, face, and content validity to be used in the Colombian context.

Subjective Happiness Scale

Despite the considerable amount of research evidence on the significant role of subjective happiness on mental health, there is no psychometric study of the Subjective Happiness Scale (SHS) in psychiatric samples. This study was aimed at exploring the psychometric properties of the SHS in a Spanish sample of patients with depressive disorders. Participants were 174 patients with a depressive disorder (70% diagnosed as major depressive disorder) who completed the SHS, the Quick Inventory of Depressive Symptomatology-Self Report (QIDS-SR16), and the EQ-5D Visual Analogue Scale (EQ-5D VAS). Depressive symptoms were also assessed by means of the 17-item Hamilton Depression Rating Scale (HDRS17) and the Clinical Global Impression-Severity (CGI-S) Scale. Dimensionality, internal consistency reliability, construct validity, and responsiveness to change of the SHS were examined. Confirmatory factor analysis replicated the original one-factor structure of the scale. The SHS exhibited good-to-excellent results for internal consistency (α = 0.83) and for convergent [EQ-5D VAS (r = 0.71)] and divergent [QIDS-SR16 (r = −0.72), HDRS17 (r = −0.60) and CGI-S (r = −0.61)] construct validity. The ability of the SHS to differentiate between depression severity levels as well as its responsiveness to clinical change were both highly satisfactory (p < 0.001 in both cases). The SHS retained the soundness of psychometric properties showed in non-clinical samples in a sample of patients with depressive disorders, which supports its use as a reliable and valid outcome measure in the treatment of such disorders.

Introduction An occupational repertoire is the array of occupations that an individual has the perceived capacity to perform at a specific point in time. The Occupational Repertoire Development Measure – Parent is a new tool that uses parent report to identify the occupations children can and do perform and their interests in and opportunities for doing them. This study aimed to test the face validity, comprehensiveness, and internal consistency of the Occupational Repertoire Development Measure – Parent as a tool to measure the occupational repertoire of children aged between 2 and 12 years. Method Twenty-nine occupational therapists completed an online questionnaire about the Occupational Repertoire Development Measure – Parent, and 27 parents completed it and then provided feedback via a structured interview. Descriptive statistics, content analysis, and the content validity index guided data analysis. Results Participants view the Occupational Repertoire Development Measure – Parent as practical, simple, and supportive of occupation-centred practice to optimize children’s development of a meaningful repertoire. Overall, self-care occupations were rated highly relevant. Lower-scoring occupations were those perceived as performed only by older children, nonessential for children with disabilities, or culturally unimportant. Conclusion Results indicate value in the further development of the Occupational Repertoire Development Measure – Parent and validate that it asks relevant questions to understand a child’s performance, engagement, and opportunities, leading to optimal repertoire development.

Abstract Background The Back Beliefs Questionnaire (BBQ) is a 14-item patient-reported questionnaire that measures attitudes and beliefs about the consequences of back pain. The BBQ has recently been translated into Norwegian, but its psychometric properties have not yet been tested. The aim of this study is to evaluate the reliability and construct validity of the BBQ when used on elderly patients with back pain. Method A prospective cohort study with a test-retest design among 116 elderly patients (> 55 years of age) seeking primary care for a new episode of back pain. Test-retest, standard error of measurement (SEM), minimal detectable change (MDC), internal consistency and construct validity by a priori hypotheses (Spearman’s- and Pearson correlation coefficient) were tested. Results A total of 116 patients, mean age (SD) 67.7 (8.3), were included and 63 patients responded to the test-retest assessment. The mean (SD) BBQ sum scores (range 9–45) were 29.8 (7.0) and 29.2 (6.7) for the test and retest respectively. The test-retest was acceptable with an intraclass correlation coefficient of 0.71 (95% CI, 0.54–0.82), SEM was 3.8 and MDC 10.5. Internal consistency with Cronbach’s alpha was good (0.82) and acceptable construct validity was supported by the confirmation of 75% of the a priori hypotheses. Conclusion The Norwegian version of the BBQ demonstrated acceptable test-retest reliability and good construct validity and can be used to assess pessimistic beliefs in elderly patients with back pain.
