Psychometrics of HRQoL questionnaires in bronchiectasis: A systematic review and meta-analysis

IntroductionUnderstanding the psychometric properties of health related quality of life (HRQoL) questionnaires can help inform selection in clinical trials.ObjectiveTo assess the psychometric properties of HRQoL questionnaires in bronchiectasis.MethodsA literature search was conducted. HRQoL questionnaires were assessed for psychometric properties (reliability, validity, minimal clinically important difference (MCID), floor/ceiling effects). Meta-analyses assessed the associations of HRQoL with clinical measures and responsiveness of HRQoL in clinical trials.Results166 studies and 12 HRQoL questionnaires were included. The BHQ, LCQ, CAT and SF-36 had good internal consistency in all domains reported (Cronbach's α≥0.7) across all studies and the QoL-B, SGRQ, CRDQ and SOLQ had good internal consistency in all domains in the majority of (but not all) studies. The BHQ, SGRQ, LCQ and CAT had good test-retest reliability in all domains reported ((intraclass correlation coefficient) ICC ≥0.7) across all studies and the QoL-B, CRDQ and SOLQ had good test-retest reliability in all domains in the majority of (but not all) studies. HRQoL questionnaires were able to discriminate between demographics, important markers of clinical status, disease severity, exacerbations and bacteriology. For HRQoL responsiveness, there was a difference between the treatment and placebo effect.ConclusionSGRQ was the most widely used HRQoL questionnaire in bronchiectasis studies and it had good psychometric properties, however good psychometric data are growing on bronchiectasis specific HRQoL questionnaires, QoL-B and BHQ. Future studies should focus on the medium-long term test-retest reliability, responsiveness and MCID in these HRQoL questionnaires which show potential in bronchiectasis.

Background: The Sexual Interest and Desire Inventory Female (SIDI-F) is a clinician-administered scale that allows for a comprehensive assessment of symptoms related to Hypoactive Sexual Desire Dysfunction (HSDD). As self-report questionnaires may facilitate less socially desirable responding and as time and resources are scarce in many clinical and research settings, a self-report version was developed (SIDI-F-SR). Aim: To investigate the agreement between the SIDI-F and a self-report version (SIDI-F-SR) and assess psychometric properties of the SIDI-F-SR. Methods: A total of 170 women (Mage=36.61, SD=10.61, range=20-69) with HSDD provided data on the SIDI-F, administered by a clinical psychologist via telephone, and the SIDI-F-SR, delivered as an Internet-based questionnaire. A subset of 19 women answered the SIDI-F-SR twice over a period of 14 weeks. Outcomes: Intraclass correlation as well as predictors of absolute agreement between SIDI-F and SIDI-F-SR, as well as internal consistency, test-retest reliability, and criterion-related validity of the SIDI-F-SR were examined. Results: There was high agreement between SIDI-F and SIDI-F-SR (ICC=.86). On average, women scored about one point higher in the self-report vs. the clinician-administered scale. Agreement was higher in young women and those with severe symptoms. Internal consistency of the SIDI-F-SR was acceptable (α=.76) and comparable to the SIDI-F (α=.74). When corrections for the restriction of range were applied, internal consistency of the SIDI-F-SR increased to .91. Test-retest-reliability was good (r=.74). Criterion-related validity was low but comparable between SIDI-F and SIDI-F-SR.

ObjectiveEven though continuity is essential after discharge, there is a lack of reliable questionnaires to measure and assess patients’ perceptions of continuity of care. The Patient Continuity of Care Questionnaire (PCCQ) addresses the period before and after discharge from hospital. However, previous studies show that the factor structure needs to be confirmed and validated in larger samples, and the aim of this study was to evaluate the psychometric properties of the PCCQ with focus on factor structure, internal consistency and stability.DesignA psychometric evaluation study. The questionnaire was translated into Swedish using a forward–backward technique and culturally adapted through cognitive interviews (n=12) and reviewed by researchers (n=8).SettingData were collected in four healthcare settings in two Swedish counties.ParticipantsA consecutive sampling procedure included 725 patients discharged after hospitalisation due to angina, acute myocardial infarction, heart failure or atrial fibrillation.MeasurementTo evaluate the factor structure, confirmatory factor analyses based on polychoric correlations were performed (n=721). Internal consistency was evaluated by ordinal alpha. Test–retest reliability (n=289) was assessed with intraclass correlation coefficient (ICC).ResultsThe original six-factor structure was overall confirmed, but minor refinements were required to reach satisfactory model fit. The standardised factor loadings ranged between 0.68 and 0.94, and ordinal alpha ranged between 0.82 and 0.95. All subscales demonstrated satisfactory test–retest reliability (ICC=0.76–0.94).ConclusionThe revised version of the PCCQ showed sound psychometric properties and is ready to be used to measure perceptions of continuity of care. High ordinal alpha in some subscales indicates that a shorter version of the questionnaire can be developed.

The Impact

Purpose The Voice Handicap Index (VHI) questionnaire assesses the impact of total laryngectomy on voice-related quality of life. This study evaluates the Mandarin VHI, including its internal consistency, test–retest reliability, content validity, and differences in scores for Mandarin alaryngeal patients with pneumatic artificial laryngeal (PA) and esophageal (ES) speech. Method Translation and validation of the VHI questionnaire was performed through the forward–backward translation technique. This study used a sample of 78 PA and 23 ES participants from Taiwan who completed the Mandarin VHI. Forty-two of the alaryngeal participants completed the Mandarin VHI twice over a period of 7–63 days. Results The measurement of the internal consistency of the Mandarin VHI showed a high Cronbach's alpha coefficient for the total score (.975) and the functional (.930), physical (.939), and emotional (.938) subscales. Based on the results of the intraclass correlation coefficients, good test–retest reliability for the total and domain scores was found (intraclass correlation coefficient = .827–.863). Conclusion The Mandarin VHI was validated as an instrument with proper internal consistency and reliability, which supports the Mandarin VHI as a valid instrument for the self-evaluation of handicaps related to voice problems in PA and ES speakers.

Background. The Preschool Activity Card Sort (PACS) is an interview-based assessment tool to measure participation of preschool children with age range from 3 to 6 years. Objective of Study. The purpose of this study was to establish the psychometric properties of the recently translated Arabic PACS (A-PACS). Methods. One hundred fifty-one Jordanian parents participated in the study representing different geographical areas. Children were almost equally distributed between males and females and into three age groups. Construct and concurrent validity were examined as well as the internal consistency of the scale and the test-retest reliability. Findings. The A-PACS was able to differentiate between the participation level of young and old children in the domains of education, community mobility, and low demand leisure of the A-PACS giving evidence to its construct validity and it significantly correlated with some aspects of the Vineland Adaptive Behavior Scale (VABS) giving evidence to its concurrent validity. The A-PACS showed excellent overall internal consistency (α=.859) for all domains and good test-retest reliability (r=.976, p<.001). Conclusion. The A-PACS can be considered as a valid and reliable tool to measure participation of preschool children with normal development from Arabic cultures. Future studies should focus on the validity of the A-PACS for use with children with disabilities.

A modified version of the Dementia Worry Scale (DWS) used the terminology “Alzheimer’s disease and related dementias” (versus the DWS’ use of “dementia”). Two studies investigated psychometric properties of the modified DWS (MDWS). Study 1 compared the psychometric properties of the DWS and MDWS; both versions had single factor structures and exhibited excellent internal consistency (αs ≥ .95). The MDWS exhibited greater test-retest reliability after a 4-week interval (DWS r = .68; MDWS r = .90). In Study 2, the MDWS again displayed a single factor structure, excellent internal consistency (α = .95), and good test-retest reliability after an 8-week interval (r = .78). Additionally, results support convergent validity between the MDWS and fear of dementia, subjective memory, general anxiety, health anxiety, and neuroticism. The MDWS is psychometrically consistent with the DWS, maintains strong test-retest reliability, and is appropriate for use in cross-sectional and longitudinal research.

Diagnostic Thinking

Abstract Diagnostic ability is essential for expert professional practice. Several instruments have been developed to assess diagnostic skills independent of specific knowledge. One such instrument is the diagnostic thinking inventory (DTI), which is used in different settings to evaluate diagnostic performance and has shown acceptable reliability and validity. The aim of the present study was to translate and validate a German version (DTI-G). Cultural adaptation and translation were performed according to international guidelines. Internal consistency and item discrimination indexes were calculated. The factorial structure of the DTI-G, test-retest reliability and known-groups validity were tested. A total of 388 physiotherapists completed the questionnaire. The internal consistency was good for the overall score of the DTI-G (Cronbach’s a = 0.84). Exploratory factor analysis yielded a five-factor solution with 21 items that explained 55% of the total variance across items. A confirmatory principal component analysis resulted in the same five-factor structure, showing an acceptable to good overall fit of the model (CFI = 0.93; RMSEA = 0.05; SRMR = 0.06). Test-retest reliability was found to be good (intraclass correlation coefficient ICC2,1 = 0.87, p < 0.001, n = 118). The difference between participants with more than 9 years of clinical experience and those with less than 9 years of clinical experience (median split) was significant (t385 = 6.00, p < 0.001), supporting known-groups validity. The results support construct validity and indicate good test-retest reliability of the DTI-G. The DTI-G can be used to measure and develop diagnostic ability of physiotherapists in clinical practice and education. Further research is necessary to validate the questionnaire for other health professions.

Introduction: There is a need to have appropriate information about the ability of Parkinson's disease (PD) patients to perform cognitive instrumental activities of daily living (IADL). The purpose of the present study was to assess the psychometric properties of the Persian version of the Penn Parkinson's Daily Activities Questionnaire-15 (PDAQ-15). Methods: A total of 165 knowledgeable informants of PD patients completed the PDAQ-15. The Clinical Dementia Rating Scale, Hoehn and Yahr staging, Hospital Anxiety and Depression Scale (HADS) and Lawton IADL scale were included in the study. Internal consistency and test-retest reliability were evaluated by Cronbach's alpha coefficient and intraclass correlation coefficient (ICC), respectively. To examine the dimensionality of the questionnaire, exploratory factor analysis was used. The construct validity was assessed using Spearman rank correlation test. To assess the discriminative validity, PDAQ-15 scores were compared across cognitive stages. Results: The PDAQ-15 showed strong internal consistency (Cronbach's α = 0.99) and test-retest reliability (ICC= 0.99). Only one dimension identified for the PDAQ-15 in the factor analysis. There was strong correlation between PDAQ-15 with depression domain of HADS scale and Lawton IADL scale. (rs = |0.71–0.95|). The correlation of PDAQ-15 with anxiety domain of HADS scale was moderate (rs = 0.66). Discriminative validity analysis showed that the PDAQ-15 has significant power to discriminate between PD patients across cognitive stages. Conclusion: These results suggest that the PDAQ-15 is a valid and reliable PD-specific instrument that can be useful in clinical and research settings.

Background: Construct of Alexithymia is important for understanding psychopathology that its assessment is of high interest as persons with difficulty in processing their emotions (either positive and negative) are more vulnerable to psychopathology problems. Objectives: The current study aimed to determine the psychometric properties of the Perth Alexithymia questionnaire (PAQ), and to describe appropriate measures for the field of clinical psychology and psychiatry. Methods: The Persian version of the PAQ was produced through forward translation, reconciliation, and back translation. The study population was all staff (soldiers) of the army force in Tehran, Iran, in 2018 - 2019. Two hundred and fifty four soldiers were selected by convenience sampling method. The following questionnaires were used to collect data: the PAQ, The Deliberate Self-Harm inventory (DSHI), Borderline Personality scale (STB), Cognitive Flexibility inventory (CFI), and Self-Compassion scale (SCS) short-form. The construct validity of the PAQ was evaluated using confirmatory factor analysis, divergent, and convergent validity. Internal Consistency and test-retest reliability (2 weeks’ interval) were applied to evaluate reliability. Data were analyzed using LISREL (version 8.8) and SSPS (version 22). Results: PAQ and its subscales were found as valid and reliable measures, with good internal consistency and good test-retest reliability. The PAQ showed good internal consistency (Cronbach’s α = 0.91). Concerning the convergent validity, PAQ and its subscales showed a significant positive correlation with self-report measures of DSHI and STB (P < 0.05). However, they were negatively correlated with Self-Compassion scale (SCS) short-form and CFI (P < 0.05), which demonstrated a good divergent validity. Moreover, while the results of this study support the five-factor models of the PAQ (RMSEA = 0.08, NFI = 0.94, CFI= 0.95), the two-factor model does not fit the data. Conclusions: The PAQ showed good validity and reliability and can be useful for evaluating Alexithymia in the army force samples. The PAQ can be considered promising as a measure in Alexithymia-related research and clinical settings.

Cognitive distortions are interrelated with all layers of cognitions, and they may be part of the treatment once they are accessed, identified, labeled, and changed. From both a research and a clinical perspective, it is of utmost importance to disentangle cognitive distortions from similar constructs. Recently, the Cognitive Distortions Questionnaire (CD-Quest), a brief and comprehensive measure, was developed to assess both the frequency and the intensity of cognitive distortions. The aim of the present study was to assess the psychometric properties of the Turkish version of the CD-Quest in a psychiatric outpatient sample. Demographic and clinical data of the participants were analyzed by descriptive statistics. For group comparisons, Student’st-test was applied. An exploratory principal components factor analysis was performed, followed by an oblique rotation. To assess the internal consistency of the scale Cronbach’sαwas computed. The correlation coefficient was calculated for test-retest reliability over a 4-week period. For concurrent validity, bivariate Pearson correlation analyses were conducted with the measures of mood severity and negatively biased cognitions. The results revealed that the scale had excellent internal consistency, good test-retest reliability, unidimensional factor structure, and evidence of concurrent and discriminant validity.
