Test Retest Reliability

Background and aims. A series of validation studies was performed on the Moynihan questionnaire to obtain data on nutrition knowledge, translated and adapted to Italian eating habits. Higher scores mean lower knowledge. Methods. Test-retest reliability was assessed administering the questionnaire at a 15-day interval in 52 inpatients. Factor structure and correlation with demographic and anthropometric characteristics were studied on a larger sample, which included a number of health professionals. Finally, sensitivity to change induced by an educational program was verified in a sample of 11 patients with type 1 diabetes. Results. Test-retest reliability was satisfactory; factor structure suggested one single principal component. Test scores were inversely correlated with age (r=0.24; p=0.02), but not with body mass index or waist circumference. Patients with higher education show a greater degree of nutrition knowledge. Among type 1 diabetic patients, an educational program induces a significant improvement of test scores (from 20.6 [18.6-22.8] to 16.6 [15.5-17.7], p=0.003). Conclusions. The Italian version of the questionnaire appears to be psychometrically adequate for its use in clinical research.

Development And Validation

Objective: The development of instruments to measure emotional maladjustment in diabetic Hispanic populations has received little attention. We present the development and validation of the Diabetes Emotional Adjustment Scale in Spanish. Method: An eighteen-item self-administered scale was construed to assess emotional adjustment in Spanish-speaking diabetic patients and the psychometric properties of the scale were assessed. The scale was applied to a sample of sixty patients and scale scores were correlated with scores on a battery of Spanish versions of established measures of psychological distress, to assess concurrent validity. Test-retest reliability was established four years later re-examining thirty-eight of the initial sixty-patients sample. Results: Split-half reliability and test-retest reliability were satisfactory. There were significant correlations between the scale results and measures of depression, trait-anxiety, family adjustment, and locus of control of behavior. A principal component analysis with varimax rotation yielded a six-factor solution explaining 50.4 percent of the total variance. Conclusions: The scale is useful as a screening instrument, but the confirmation of factor structure stability and the correlation of the scale results with objective measures of metabolic control, require further investigation.

Abstract Background Training in psychiatry requires specific knowledge, attitudes, and skills that are obtainable by simulation, of which the use is only recent and still needs further development. Evidence is accumulating on its effectiveness but requires further validation for medical students. We aimed to evaluate the effectiveness of a single-day optional teaching program in psychiatry by simulation for medical students and validate a scale measuring Confidence in Psychiatric Clinical Skills (CPCQ), as part of the assessment. Methods This was a controlled study in a French University that compared (using paired-sample Student t-tests) knowledge and attitudes (university grades and CPCQ scores) before, just after teaching with simulated patients, and 2 months later. Satisfaction with the program (including the quality of the debriefing) was also investigated. The CPCQ scale was validated by assessing the factor structure, internal consistency, and test-retest reliability. Finally, a comparison was run with a control group who received the usual psychiatric instruction using covariance analyses. Results Twenty-four medical students were included in the simulation group and 76 in the control group. Just after the simulation, knowledge and attitudes increased significantly in the simulation group. Satisfaction with the training and debriefing was very high. The CPCQ scale showed good psychometric properties: a single-factor structure, acceptable internal consistency (α = 0.73 [0.65–0.85]), and good test-retest reliability (ICC = 0.71 [0.35–0.88]). Two months after the simulation, knowledge and attitudes were significantly higher in the simulation group than the control group, despite a lack of difference in knowledge before the simulation. Conclusions Adding a simulation program in psychiatry to the usual teaching improved the knowledge and confidence of medical students. The CPCQ scale could be used for the evaluation of educational programs.

Purpose Relational dynamics between patients and staff in forensic settings can be complicated and demanding for both sides. Reflective practice groups (RPGs) bring clinicians together to reflect on these dynamics. To date, evaluation of RPGs has lacked quantitative focus and a suitable quantitative tool. Therefore, a self-report tool was designed. This paper aims to pilot The Relational Aspects of CarE (TRACE) scale with clinicians in a high-secure hospital and investigate its psychometric properties. Design/methodology/approach A multi-professional sample of 80 clinicians were recruited, completing TRACE and attitudes to personality disorder questionnaire (APDQ). Exploratory factor analysis (EFA) determined factor structure and internal consistency of TRACE. A subset was selected to measure test–retest reliability. TRACE was cross-validated against the APDQ. Findings EFA found five factors underlying the 20 TRACE items: “awareness of common responses,” “discussing and normalising feelings;” “utilising feelings,” “wish to care” and “awareness of complicated affects.” This factor structure is complex, but items clustered logically to key areas originally used to generate items. Internal consistency (α = 0.66, 95% confidence interval (CI) = 0.55–0.76) demonstrated borderline acceptability. TRACE demonstrated good test–retest reliability (intra-class correlation = 0.94, 95% CI = 0.78–0.98) and face validity. TRACE indicated a slight negative correlation with APDQ. A larger data set is needed to substantiate these preliminary findings. Practical implications Early indications suggested TRACE was valid and reliable, suitable to measure the effectiveness of reflective practice. Originality/value The TRACE was a distinctive measure that filled a methodological gap in the literature.

This study examined the reliability of the Revised Competitiveness Index by investigating the test-retest reliability, interitem reliability, and factor structure of the measure based on a sample of 280 undergraduates (200 women, 80 men) ranging in age from 18 to 28 years ( M = 20.1, SD = 2.1). The findings indicate that the Revised Competitiveness Index has high test-retest reliability, high interitem reliability, and a stable factor structure. The results support the assertion that the Revised Competitiveness Index assesses competitiveness as a stable trait rather than a dynamic state.

Background. Sleep disorders are common in perinatal women and may underlie or trigger anxiety and depression. We aimed to translate and validate and evaluate the psychometric properties of the Italian version of the Insomnia Symptom Questionnaire (ISQ), in a sample of women during late pregnancy and 6-months postpartum according to the DSM-5 criteria. Methods. The ISQ was administered to 292 women prenatally along with other measures of sleep quality, depression, and anxiety, to examine its construct and convergent validity. Women were readministered the ISQ six months postdelivery to assess test–retest reliability. Women were divided into DSM-5 No-Insomnia (N = 253) and Insomnia (N = 39) groups. Results. The insomnia group had received more psychopharmacotherapy, had more psychiatric family history, increased rates of medically assisted reproduction, of past perinatal psychiatric disorders, and scored higher on almost all TEMPS-A dimensions, on the EPDS, HCL-32, PSQI, and on ISQ prenatally and postnatally. ISQ scores correlated with all scales, indicating adequate convergent and discriminant validity; furthermore, it showed antenatal–postnatal test–retest reliability, 97.5% diagnostic accuracy, 79.5% sensitivity, 94.9% specificity, 70.5% positive predictive power, and 92.8% negative predictive power. Conclusions. The ISQ is useful, valid, and reliable for assessing perinatal insomnia in Italian women. The Italian version showed equivalent properties to the original version.

The aim of the present study is to test the factor structure and reliability of the Experience of Close Relationships-Relationship Structures Scale (ECR-RS) mother, father, romantic partner, close friend forms among Turkish adolescents. In order to test the structure validity of the ECR-RS, exploratory factor analysis is performed on a sample of 214 participants in Study 1, and to further investigate the structure validity, confirmatory factor analysis is performed on a second sample of 286 participants in Study 2. Within the scope of the reliability studies of the ECR-RS, internal reliability and test–retest reliability of the Turkish ECR-RS are also tested. The results of the explanatory and confirmatory factor analysis, Cronbach’s alpha coefficients, and test–retest reliability scores supported the original two-factor structure (attachment avoidance and attachment anxiety) for all forms of the ECR-RS among Turkish adolescents.

The factor structure, the concurrent validity, and test–retest reliability of the Czech translation of the Gifted Rating Scales-School Form [GRS-S; Pfeiffer, S. I., & Jarosewich, T. (2003). GRS (gifted rating scales) - manual. Pearson] were evaluated. Ten alternative models were tested. Four models were found to exhibit acceptable fit and interpretability. The factor structure was comparable for both parent ( n = 277) and teacher raters ( n = 137). High correlations between the factors suggest that raters might be subject to a halo effect. Ratings made by teachers show a closer relationship with criteria (WJ IE II COG, CFT 20-R, and TIM3–5) than ratings made by parents. Test–retest reliability of teacher rating (with median 93 days) was quite high for all GRS-S subscales ( r = .84–.87).

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.

Background: With the rapid development of new insulin delivery technology, measuring patient experience has become especially pertinent. The current study reports on item development, psychometric validation, and intended use of the newly developed Diabetes Impact and Device Satisfaction (DIDS) Scale. Method: The DIDS Scale was informed by a comprehensive literature review, and field tested as part of two focus groups. The finalized measure was used at baseline and 6 months post-assessment with a large US cohort. Exploratory factor analyses (EFAs) were conducted to determine and confirm factor structure and item selection. Internal reliability, test–retest reliability, and convergent/divergent validity of the emerged factors were tested with demographics, diabetes-specific information, and diabetes behavioral and satisfaction measures. Results: In all, 778 participants with type 1 diabetes (66% female, mean age 47.13 ± 17.76 years, 74% insulin pump users) completed surveys at both baseline and post-assessment. EFA highlighted two factors—Device Satisfaction (seven items, Cronbach’s α = 0.85-0.90) and Diabetes Impact (four items, Cronbach’s α = 0.71-0.75). DIDS Scale demonstrated good concurrent validity and test–retest reliability. Conclusion: The DIDS Scale is a novel and a brief assessment tool with robust psychometric properties. It is recommended for use across all insulin delivery devices and is considered appropriate for use in longitudinal studies. Future studies are recommended to evaluate the performance of DIDS Scale in diverse populations with diabetes.
