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.

Abstract Background The use of validated questionnaires to assess the perception of teamwork can be an early step in improving team training activities. Team-STEPPS® Teamwork Perception Questionnaire (T-TPQ) has been adapted and validated for hospital setting use in several countries. Due to linguistic and cultural differences, there is need to test the psychometrics of the adapted versions. However, no research have not yet assessed the psychometric properties of the Persian T-TPQ. Therefore, this study aims to assess the internal consistency reliability and construct validity of an Iranian version of the Team-STEPPS® Teamwork Perception Questionnaire (IR-T-TPQ). Methods To conduct this study, we undertook a cross-sectional survey approach between May 2020 and January 2021. In total, 404 nurses were recruited by convenience sampling technique from 10 teaching hospitals in Tabriz, Iran. Internal consistency reliability was analyzed using Cronbach’s alpha coefficient. Confirmatory factor analysis was performed to test the construct validity of the instrument. Results Cronbach’s alpha coefficients for each subscale were acceptable, ranging from 0.84 to 0.92, as well as for the total IR-T-TPQ (α = 0.96). The confirmatory factor analysis demonstrated a five-factor model, all of whose fit indices were acceptable, except for the goodness-of-fit index and normed fit index (χ2 (df) 1332 (550), p < 0.001, Normed chi-square (χ2/df) = 2.423, RMSEA = 0.059, TLI = 0.897, CFI = 0.904, AGFI = 0.814). Conclusions The psychometric properties of the IR-T-TPQ resulted in acceptable levels of internal consistency reliability and construct validity, respectively, in Iranian hospital nurses. Further study is needed to compare the teamwork level of nurses in various settings or to evaluate the effectiveness of the teamwork intervention using this validated and reliable tool.

Abstract Background The absence of Respectful Maternity Care (RMC) deters mothers from seeking maternity care services. Given the importance of RMC and the lack of a standard tool for its assessment in Iran, the present study was conducted to translate and assess the psychometric properties of the RMC questionnaire in Iranian women. Methods Forward-backward method was used for translating the questionnaire from English into Persian. A total of 265 postpartum women entered the study by simple random sampling from public and private hospitals in Tabriz, Iran. The validity of the questionnaire was confirmed through the face, content and construct validity. Construct validity was assessed through exploratory and confirmatory factor analyses. The internal consistency and test-retest reliability were used to confirm the reliability of the questionnaire. Internal consistency was examined by measuring the Cronbach’s alpha in a sample of 20 mothers, and test-retest stability by calculating the Intraclass Correlation Coefficient (ICC) in the same group of mothers, who had completed the questionnaire twice with a two-week interval. Results The exploratory factor analysis led to the extraction of one factor. Item 12 was eliminated due to its low factor loading. X2/df was less than 5, and RMSEA was less than 0.08, which confirms the validity of this model. The Cronbach’s alpha coefficient was obtained as 0.93 and ICC (with 95% confidence interval) as 0.98 (0.96 to 0.99). Conclusion The results of the study demonstrated that the Iranian RMC scale can be used as a valid and reliable instrument to assess RMC in Iran.

This study explored the psychometric properties and construct validity of a new measure of hostility, the Hostile Interpretations Questionnaire (HIQ). The sample consisted of 146 violent offenders incarcerated in a Canadian federal institution. Participants completed a battery of self-report psychometric measures as part of a pre-release psychological assessment. Results indicated that the HIQ had acceptable internal consistency reliability ( r = .86) and demonstrated construct validity with relevant anger/hostility measures. Implications of the findings with respect to theory and practice are considered.

The purpose of this article is to review 12 completed studies that have used the Resilience Scale (Wagnild & Young, 1993). Completed studies were identified through PubMed and CINAHL. Studies that identified Resilience Scale scores, sample descriptions, and tested relationships between the Resilience Scale and study variables were selected for inclusion. Cronbach’s alpha coefficients ranged from .72 to .94 supporting the internal consistency reliability of the Resilience Scale. Hypothesized relationships between the Resilience Scale and study variables (e.g., forgiveness, stress, anxiety, health promoting activities) were supported strengthening the evidence for construct validity of the Resilience Scale. In the studies reported here, the Resilience Scale has been used with a variety of individuals of different ages, socioeconomic, and educational backgrounds. The Resilience Scale has performed as a reliable and valid tool to measure resilience and has been used with a wide range of study populations.

Background and Purpose: To assess the psychometrics of the French language Quality of Prenatal Care Questionnaire (QPCQ). Methods: Data from 302 women were used in a confirmatory factor analysis and in assessment of construct validity through hypothesis testing and internal consistency reliability using Cronbach’s alpha. Results: The 6 factors (subscales) were verified and confirmed. Hypothesis testing further supported construct validity. The overall QPCQ had acceptable internal consistency reliability (Cronbach’s alpha = .97) as did 5 subscales (Cronbach’s alpha = .70–.92); the Sufficient Time subscale had poorer reliability (Cronbach’s alpha = .61). Conclusions: The French language QPCQ is a valid and reliable self-report measure of prenatal care quality. It can be used in research and in quality improvement work to strengthen prenatal care services.

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.

Abstract Background Community care professionals need to encourage older adults in performing functional activities to maintain independence. However, professionals often perform functional activities on behalf of older adults. To change this, insights into the behavior and barriers of professionals in encouraging activities are required. In the current study, the MAINtAIN questionnaire, which was developed for nursing homes, was adopted. The objective was to create a modified version that is suitable for measuring behavior and barriers of community care professionals in encouraging functional activities of clients in the community care setting. The overall aims were to assess the content validity, construct validity, and internal consistency of the modified version. Methods Data was collected by qualitative and quantitative methods in two phases. During phase one, the MAINtAIN was assessed on appropriateness and feasibility by community nurses (N = 7), and the adapted questionnaire was assessed on content validity by research experts (N = 9) and community care professionals (N = 18). During phase two, the psychometric properties of the adapted MAINtAIN-C were assessed in community care professionals (N = 80). Construct validity was evaluated by an Exploratory Factor Analysis (EFA), and internal consistency was determined by calculating Cronbach’s alpha coefficients. Results The formulation, verbs, and wording of the MAINtAIN were adapted; some items were excluded and relevant items were added, resulting in the MAINtAIN-C with two scales, showing good content validity. The Behaviors scale (20 items) measures perceived behavior in encouraging functional activities, expressing good internal consistency (Cronbach’s alpha: .92). The Barriers scale measures barriers in encouraging functional activities related to two dimensions: 1) the clients’ context (7 items), with good internal consistency (.78); and 2) the professional, social, and organizational contexts (21 items), showing good internal consistency (.83). Conclusions The MAINtAIN-C seems promising to assess the behavior and barriers of community care professionals in encouraging functional activities. It can be used to display a possible difference between perceived and actual behavior, to develop strategies for removing barriers in encouraging activities to foster behavioral change. The results also provide guidance for further research in a larger sample to obtain more insight into the psychometric properties.

The Revised Piper Fatigue Scale (R-PFS) is an instrument designed to measure subjective fatigue that was developed in samples with physical illness. Its psychometric properties in nonclinical samples are unknown. The purpose of this study was to examine the psychometric properties of the R-PFS in a sample of caregivers of stroke survivors. The convenience sample of 132 caregivers was primarily women (74%), White (71%), college-educated (73%), and employed (52%), with a mean age of 56.7 years (SD = 13.71). Internal consistency reliabilities for the four R-PFS subscales and the total scale were excellent, ranging from .90 to .97. Principal axis factor analysis with oblique rotation was conducted to examine construct validity of the R-PFS. A three-factor solution explained 75.9% of the common variance. Two factors totally replicated the behavioral/severity and affective meaning subscales of the R-PFS. The third factor incorporated a combination of Piper’s sensory and cognitive/mood subscales and appeared to summarize how fatigue makes the caregiver feel. The R-PFS demonstrated strong internal consistency reliability and construct validity in this sample. However, data suggest that caregivers may perceive certain feelings associated with fatigue as conceptually similar when these feelings are conceptually distinct in Piper’s breast cancer sample. The study supports the need for psychometric evaluation of instruments developed in clinical populations prior to their use in nonclinical populations.

Objectives: The 10-item Connor-Davidson Resilience Scale (CD-RISC 10) is a brief instrument measuring resilience in adults. The scale has shown sound psychometric properties in different populations and cultures. Our objectives were to cross-culturally adapt the CD-RISC 10 into Danish and to establish the psychometric properties of the Danish version in terms of internal consistency, construct validity and longitudinal validity. Methods: The CD-RISC 10 was translated using established guidelines. Employees ( N=272) at hospitals in the Central Denmark Region completed questionnaires at baseline and three months follow-up. Questionnaires included the translated Danish version of the CD-RISC 10 and the 10-item Perceived Stress Scale (PSS-10). Internal consistency was assessed by Cronbach’s alpha and construct and longitudinal validity by correlating CD-RISC 10 and PSS-10 baseline scores and change scores from baseline to follow-up. Results: The Danish CD-RISC 10 provides acceptable internal consistency (Cronbach’s alpha = 0.87). Analysis of construct validity revealed a negative correlation with the PSS-10 at baseline ( r=−.63 [95%CI: −.70; −.55], p<.0001). Analysis of longitudinal validity similarly demonstrated a negative correlation on change scores from baseline to follow-up ( r=−.51 [95%CI: −.62; −.39], p<.0001). Conclusions: The scale has acceptable psychometric properties as an instrument for measuring resilience in a Danish-speaking population.
