This study aimed to validate the Short-Form 12-Item Survey—version 2 (SF−12v2) in an older (≥65 years old) US population as well as estimate disutilities associated with relevant conditions, using data from the Medical Expenditure Panel Survey longitudinal panel (2014–2015). The physical component summary (PCS) and mental component summary (MCS) scores were examined for reliability (internal consistency, test-retest), construct validity (convergent and discriminant, structural), and criterion validity (concurrent and predictive). The study sample consisted of 1040 older adults with a mean age of 74.09 years (standard deviation: 6.19) PCS and MCS demonstrated high internal consistency (Cronbach’s alpha—PCS: 0.87, MCS: 0.86) and good and moderate test-retest validity, respectively (intraclass correlation coefficient: PCS:0.79, MCS:0.59)). The questionnaire demonstrated sufficient convergent and discriminant ability. Confirmatory factor analysis showed adequate fit with the theoretical model and structural validity (goodness of fit = 0.9588). Concurrent criterion validity and predictive criterion validity were demonstrated. Activity limitations, functional limitations, arthritis, coronary heart disease, diabetes, myocardial infarction, stroke, angina, and high blood pressure were associated with disutilities of 0.18, 0.15, 0.06, 0.07, 0.07, 0.06, 0.09, 0.06, and 0.08, respectively, and demonstrated the responsiveness of the instrument to these conditions. The SF−12v2 is a valid and reliable instrument in an older US population.

Purpose: The purpose of this study was to develop a shortened version of the Instrument of Diabetes Self-Care Agency (IDSCA). Methods: In the development of the shortened version of IDSCA, intraclass correlation coefficient 2 (ICC2) analysis was done to determine items to be deleted. However, the 7 subscales were retained. The shortened IDSCA was evaluated for internal consistency, reproducibility, concurrent validity, criterion-related validity, and goodness of fit. Results: The shortened IDSCA included 35 items addressing 7 subscales. High ICC2 (.804) and a high Cronbach’s alpha (.89) indicate internal consistency and reproducibility. A high correlation (.62) between the shortened version of the IDSCA and the Self-Care Agency Questionnaire indicated concurrent validity. Conclusion: The shortened IDSCA provides a reliable and valid measure of self-care agency of individuals with diabetes.

The aim of this study was translating and exploring psychometric properties of Serbian Pittsburgh Sleep Quality Index (PSQI) in a sample of “good” and “bad” sleepers suffering from depression or obstructive sleep apnea (OSA). Formal translation and validation were performed on a sample of healthy controls, patients with untreated OSA, and with diagnosed major depressive disorder with evaluation of internal consistency, test–retest reliability, and construct and criterion validity. Controls and OSA subgroups were recruited from a larger sample of commercial drivers. One hundred and forty subjects, 84.3% male, 22–67 years old, were included. OSA subgroup had 59 subjects and depression subgroup had 40 subjects (22 females). Mean ± SD total PSQI was 3.5 ± 2.2 in controls, 4.9 ± 3.6 in OSA subjects, and 9.0 ± 4.9 in patients with depression. Cronbach’s α for total PSQI was 0.791. Subscale scores were significantly correlated to global PSQI in all subgroups. Intraclass correlation coefficient for global PSQI was 0.997 ( p < .001). Epworth Sleepiness Scale score was significantly correlated to global PSQI (ρ = 0.333, p < .001). Three subgroups differed significantly in total PSQI and PSQI ≥ 5, even after adjustments for age and gender ( p < .001). OSA patients had higher mean PSQI than controls but not significantly ( p = .272). PSQI-reported sleep latency did not correlate with PSG-measured sleep latency ( r = .130, p = .204). Total PSQI was significantly correlated to OSA severity (ρ = 0.261, p < .05). Serbian PSQI showed good internal consistency, test–retest reproducibility, and adequate construct and criterion validity, which supports further exploration of its use as a sleep quality screening tool in different target populations.

In our country, outcome measures are needed to evaluate the results of occupational therapy in amputees. This study aimed to cross-culturally adapt the Reintegration to Normal Living Index (RNLI) and to evaluate the reliability and validity of a Turkish version of the RNLI. The Turkish version of the RNLI was applied to 120 amputees. Cronbach’s alpha coefficient and the intraclass correlation coefficient (ICC) were used to determine internal consistency and test–retest reliability, respectively. Criterion validity was assessed using Short Form 36 (SF-36). The Turkish version of the RNLI presented reliable results in repeated assessments (ICC = .88), and the internal consistency of the RNLI was high (Cronbach’s α coefficient = .89). A statistically significant relationship was found between RNLI and SF-36 ( p < .05). The Turkish RNLI is a reliable and valid tool to evaluate the level of reintegration to normal living for amputees.

Abstract Objectives To examine the validity and reliability of the Mandarin version of the Treatment Burden Questionnaire (TBQ) among stroke patients. Background Stroke patients need long-term management of symptoms and life situation, and treatment burden has recently emerged as a new concept that can influence the health outcomes during the rehabilitation process. Methods The convenience sampling method was used to recruit 187 cases of stroke patients in a tertiary grade hospital in Tianjin for a formal investigation. Item analysis, reliability and validity tests were carried out. The reliability test included internal consistency and test–retest reliability. And as well as content, structure and convergent validity were performed for the validity test. Results Of the 187 completed questionnaires, only 180 (96.3%) were suitable for analysis. According to the experts’ evaluation, the I-CVI of each item was from 0.833 to 1.000, and the S-CVI was 0.967. The exploratory factor analysis yielded three-factor components with a cumulative variation of 53.054%. Convergent validity was demonstrated using measures of Morisky’s Medication Adherence Scale 8 (r = –0.450, P &lt; 0.01). All correlations between items and global scores ranged from 0.403 to 0.638. Internal consistency reliability and test–retest reliability were found to be acceptable, as indicated by a Cronbach’s α of 0.824 and an intraclass correlation coefficient of 0.846, respectively. Conclusions The Mandarin TBQ had acceptable validity and reliability. The use of TBQ in the assessment of treatment burden of stroke survivor may benefit health resources allocation and provide tailor therapeutic interventions to construct minimally disruptive care.

Abstract Background Endometriosis is a common problem in women of reproductive age and has impacts on health-related quality of life and productivity. Fatigue is an important part of the burden of endometriosis, it is not often included as an endpoint in clinical trials. Objectives The study assessed the psychometric properties of the PROMIS Fatigue Short Form 6a in women with moderate-to-severe endometriosis-associated pain. Methods In a phase III double-blind, placebo-controlled clinical trial (NCT01620528), women aged 18–49 years with moderate-to-severe endometriosis-related pain were randomized to elagolix 150 mg once daily, elagolix 200 mg twice daily, or placebo for 6 months. PROMIS Fatigue and dysmenorrhea and non-menstrual pelvic pain (NMPP) scores were assessed at baseline and months 1, 3, and 6, and Patient Global Impression of Change (PGIC) was assessed at months 1, 3, and 6. Reliability (internal consistency and test-retest reliability), construct validity (convergent and known groups validity), and responsiveness were evaluated. Results The analysis included 871 women, mean age 31.5 years. Internal consistency supported a single concept (Cronbach’s alpha 0.93). For the 238 patients with no change in PGIC at month 1, the intraclass correlation coefficient for the PROMIS Fatigue T-score was 0.7 and paired t-test statistically significant (2.84, p = 0.0049). Correlations with other measures were expected to be fairly low as concepts were not redundant. The PROMIS Fatigue discriminated among known groups with mean scores of 55.3, 62.3, and 65.8 at month 3 (PGIC improvement, no change, worsening, respectively). Statically significant discrimination, and change score responsiveness, were seen using clinically relevant anchors (dysmenorrhea and NMPP) at months 3 and 6 between responders and non-responders. Anchor-based (PGIC) responsiveness showed significant improvement from baseline to months 3 and 6 (p < 0.0001). Conclusions PROMIS Fatigue has good reliability, validity, and responsiveness in women with moderate-to-severe endometriosis-associated pain.

Background: Each year, nearly 800,000 people experience a new or recurrent stroke. To assess changes in neurological status during hospitalization, nurses are required to complete the 15-item National Institute of Health Stroke Scale (NIHSS), which is time consuming and therefore, may not be completed as thoroughly as it should. To ensure these patients are being effectively and adequately assessed, there is a need for an abbreviated NIHSS, which can be completed in a shorter time frame. Purpose: The purpose of this study was to determine the merits of an abbreviated NIHSS using seven items considered to be key to determining changes in neurological status. Methods: Over a six month period, 100 scores from the 15-item NIHSS were collected on a sample of 92 acute care stroke patients who had a mean age of 64.2; 52% were female. Seven items were calculated, which included level of consciousness, left and right arm motor movement, left and right leg motor movement, speech fluency, and speech clarity. To assess internal consistency reliability of the 7-item NIHSS, Cronbach's α was computed. To assess criterion validity, the 7-item NIHSS and 15-item NIHSS were correlated using Pearson's r . Results: The 15-item NIHSS ranged from 1 to 37, with a mean of 8.6. The 7-item NIHSS ranged from 0 to 24, with a mean of 4.9. For the 7-item NIHSS, Cronbach's α was .82 and Pearson's r was .96 (p<.001), when correlated with the 15-item NIHSS. Conclusions: Assessment of the acute stroke patient using the 15-item NIHSS is time-consuming, and therefore, may be underutilized. An abbreviated 7-item NIHSS demonstrated satisfactory evidence of internal consistency reliability and criterion validity, when correlated with the 15-item NIHSS, suggesting the 7-item version may be a suitable alternative to the longer version. More psychometric testing is warranted to fully evaluate reliability and validity of the 7-item NIHSS.

Bullying among children and adolescents can have detrimental effects on their physical and mental health. The first step in the identification of bullying is the detection of relevant signs and behaviours, with the use of appropriate instruments. The widely used Peer Relation Questionnaire (PRQ)has been developed to measure bullying behaviour in children and adolescents. The aim of this study was to translate and validate this instrument in the Greek language in a school sample of children and adolescents. Α sample of 193 students (mean age ± SD 11.44 ± 1.26 years, girls 49.7%), was recruited from elementary and junior high schools of the public and private sector, in the capital of Athens, Greece. Along with the Peer Relation Questionnaire, the Stress in Children questionnaire and a structured inquiry regarding satisfaction from various aspects of life were used to assess the criterion validity of the Peer Relation Questionnaire. Results revealed good psychometric properties of the questionnaire in the Greek language. The principal component analysis resulted in two subscales that demonstrated an adequate internal consistency and a significant correlation with stress and satisfaction parameters, suggesting satisfying criterion validity. Meaningful associations between demographic characteristics and the subscales were also found. The Greek version of the Peer Relation Questionnaire-short form can be used as a valid tool to measure bullying behaviour in children and adolescents.
