Individualised Care Scale‐Nurse: Construct validity and internal consistency of the Spanish version

Abstract Background. The Fonseca Anamnestic Index (FAI) offers a simple method to screen temporomandibular disorders (TMD). This study aimed to validate the standard version of the FAI in a Spanish population and to analyze the clinimetric properties of the Spanish version of the FAI in patients with TMD.Methods. The sample consisted of 179 subjects aged over 18 years, of which 119 were diagnosed with TMD and 60 were healthy controls. Construct validity (exploratory factor analysis), internal consistency, test-retest reliability, and concurrent validity were analyzed. To discriminate between patients with and without TMD, Receiver Operating Characteristic (ROC) curve analysis was performed.Results. The Spanish version of the FAI showed construct validity formed by three factors. Cronbach’s alpha was 0.820, indicating good internal consistency. The reliability of the items measured with the weighted kappa coefficient was between 0.588 and 0.899, varying between moderate to almost perfect. The intraclass correlation coefficient (ICC) of the total score was 0.938, indicating excellent reliability. The standard error of measurement (SEM) was 6.42, with a minimum detectable change (MDC) of 12.59 points. The concurrent validity showed a significant correlation with headache, neck pain, vertigo and the Mental Component Summary (SF-12 MCS) of the SF-12. However, the relationship with the Physical Component Summary (SF-12 PCS) was not significant. The ROC curve analysis showed a good accuracy of the FAI in differentiating between healthy and TMD patients with an area under the curve (AUC) = 0.869, corresponding to a cut-off point for the FAI of >35 points, with a sensitivity = 83.19% and a specificity = 78.33%.Conclusions. The Spanish version of the FAI is a valid and reliable instrument for diagnosing people with TMD, with appropriate general clinimetric properties. Discrimination between patients with and without TMD is excellent.

Background: The Standardised Nordic Questionnaire (SNQ) is an instrument to analyse the musculoskeletal symptoms in an ergonomic or occupational health context. We aimed to cross-culturally adapt and evaluate the psychometric properties of the SNQ among Spanish musicians. Methods: Cross-cultural adaptation and psychometric validation (reliability, validity, and feasibility) was performed. Reliability was analysed by test-retest reliability (Cohen’s Kappa) and internal consistency (Kuder–Richardson). Content and face validity were measured by the Expert Committee and the opinion of participants. Construct validity (Mann–Whitney U test) was measured by comparing with questionnaires used to assess pain and disability in neck, shoulders, upper back, and low back regions. Feasibility was calculated with the average response time. Results: A total of 312 Spanish musicians were included. The Spanish version of SNQ achieved good semantic, conceptual, idiomatic, and content equivalence. For most of the variables, test-retest reliability was good to very good (k = 0.60–0.81). The internal consistency showed good to acceptable (Kuder–Richardson 20 (KR20) = 0.737–0.873). Participants with versus without musculoskeletal problems in a related region showed significantly higher disability/pain, indicating a good construct validity. About the feasibility, the average response time of the questionnaire was 6 min (±2). Conclusions: The results show that the Spanish SNQ is reliable, valid, and feasible screening tool to assess musculoskeletal problems among musicians.

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.

Abstract Background The objective of this study was to verify the reliability, discriminatory power and construct validity of the Kidscreen-27 questionnaire in Brazilian adolescents. Methods Adolescents that participated of the pilot study (210 adolescents; 52.9% boys; 13.7 years old) and of the baseline (816 participants; 52.7% girls; 13.1 years old) of the Movimente Project in 2016/2017 composed the sample of the present study. This project was carried out in six public schools in the city of Florianópolis, Santa Catarina, Brazil. Test–retest reproducibility was assessed by the intraclass correlation coefficient and Gwet coefficient; internal consistency through McDonald's Omega; Hankins' Delta G coefficient verified the scale's discriminatory power and; confirmatory factor analysis to assess construct validity. Results Reproducibility values ranged from 0.71 to 0.78 for the dimensions (ICC), and ranged from 0.60 to 0.83 for the items (Gwet). McDonald's Ômega (0.82–0.91) for internal consistency measures. Discriminatory power ranging from 0.94 for the dimension Social Support and Friends to 0.98 for Psychological Well-Being. The factorial loads were > 0.40, except for item 19 (0.36). The fit quality indicators of the model were adequate (X2[df] = 1022.89 [311], p < 0.001; RMSEA = 0.053 (0.049–0.087); CFI = 0.988; TLI = 0.987), confirming the five-factor structure originally proposed. Conclusions The Brazilian-version Kidscreen-27 achieved good levels of reproducibility, internal consistency, discriminatory power and construct validity. Its use is adequate to measure the health-related quality of life of adolescents in the Brazilian context.

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.

Abstract Background and aim Growing attention is being given to utilising physical function measures to better understand and manage knee osteoarthritis (OA). The Fremantle Knee Awareness Questionnaire (FreKAQ), a self-reported measure of body-perception specific to the knee, has never been validated in Italian patients. The aims of this study were to culturally adapt and validate the Italian version of the FreKAQ (FreKAQ-I), to allow for its use with Italian-speaking patients with painful knee OA. Methods The FreKAQ-I was developed by means of forward–backward translation, a final review by an expert committee and a test of the pre-final version to evaluate its comprehensibility. The psychometric testing included: internal structural validity by Rasch analysis; construct validity by assessing hypotheses of FreKAQ correlations with the knee injury and osteoarthritis outcome score (KOOS), a pain intensity numerical rating scale (PI-NRS), the pain catastrophising scale (PCS), and the Hospital anxiety and depression score (HADS) (Pearson’s correlations); known-group validity by evaluating the ability of FreKAQ scores to discriminate between two groups of participants with different clinical profiles (Mann–Whitney U test); reliability by internal consistency (Cronbach’s alpha) and test–retest reliability (intraclass correlation coefficient, ICC2.1); and measurement error by calculating the minimum detectable change (MDC). Results It took one month to develop a consensus-based version of the FreKAQ-I. The questionnaire was administered to 102 subjects with painful knee OA and was well accepted. Internal structural validity confirmed the substantial unidimensionality of the FreKAQ-I: variance explained was 53.3%, the unexplained variance in the first contrast showed an eigenvalue of 1.8, and no local dependence was detected. Construct validity was good as all of the hypotheses were met; correlations: KOOS (rho = 0.38–0.51), PI-NRS (rho = 0.35–0.37), PCS (rho = 0.47) and HADS (Anxiety rho = 0.36; Depression rho = 0.43). Regarding known-groups validity, FreKAQ scores were significantly different between groups of participants demonstrating high and low levels of pain intensity, pain catastrophising, anxiety, depression and the four KOOS subscales (p ≤ 0.004). Internal consistency was acceptable (α = 0.74) and test–retest reliability was excellent (ICC = 0.92, CI 0.87–0.94). The MDC95 was 5.22 scale points. Conclusion The FreKAQ-I is unidimensional, reliable and valid in Italian patients with painful knee OA. Its use is recommended for clinical and research purposes.

Background: The mini-suffering state examination is a valid and reliable measure that have been used to assess suffering in patients with advanced cancer. The aim of this study was to carry out a psychometric analysis of the Spanish version of the mini-suffering state examination. Method: A validation study was conducted. Seventy-two informal caregivers of deceased patients in palliative care were included in this study. A psychometric testing of content validity, internal consistency, and convergent validity with the Spanish version of the quality of dying and death questionnaire was performed. Results: The original instrument was modified to be used by informal caregivers. The content validity was acceptable (0.96), and the internal consistency was moderate (α = 0.67). Convergent validity was demonstrated (r = −0.64). Conclusion: The Spanish modified version of the MSSE showed satisfactory measurement properties. The Spanish modified version of MSSE can be useful to facilitate screening, monitor progress, and guide treatment decisions in end-of-life cancer patients.

Environment Scale

Abstract Background Torture methods have traditionally been quantified using checklists. However, checklists fail to capture accurately both the almost infinite range of available methods of torture and the victims’ subjective experience. The Torturing Environment Scale (TES) was designed as a multidimensional alternative that groups torture methods according to the specific human function under attack. This study aims to do an exploratory assessment of the internal consistency reliability and discriminatory validity of the TES as part of a construct validity assessment in a sample of Basque torture survivors. Methods We applied the TES to a sample of 201 torture survivors from the Istanbul Protocol Project in the Basque Country Study (IPP-BC) to profile torturing environments in detention. To estimate the internal consistency reliability of the scale, categorical omega values were obtained for each subscale of the TES. To assess its discriminatory validity, the “known groups” method was used comparing mean scorings by gender, state security forces involved in the detention, and decade (the 1980s to the present) when the events took place. Results Men reported more physical pain, while women reported more attacks on self-identity and sexual integrity. The TES also showed significant differences as regards the security forces involved in the detention: Civil Guard (a militarised police) used more manipulation of the environment, threats, fear, pain and extreme pain, as compared to national and regional corps. Finally, although patterns of torture remained mostly unchanged across decades, more recent detentions included more emphasis on psychological attacks: context manipulation, humiliation linked to sexual identity, and attacks to meaning and identity. For all subscales of the TES, categorical omega values ranged from 0.44 to 0.72. Conclusion The TES may be a useful tool in profiling torturing environments. Its sensitivity to key contextual variables supports the discriminatory validity of the scale. While some of the subscales showed an acceptable degree of internal consistency, others require further analysis to improve reliability. The scale provides unique insights into the profile of contemporary torture. It will allow for future quantitative research on the relationship between different torturing environments and the medical and psychological consequences thereof.

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]
