Mo1288 Internal Consistency and Test-Retest Reliability of the Early Trauma Inventory Self Report-Short Form (ETI-SR) in Patients With Irritable Bowel Syndrome (IBS) and Healthy Controls

Background: The Quality of Life–Alzheimer’s Disease (QoL-AD) scale is a widely used measure of quality of life (QoL) in dementia. Although the instrument has been validated in several languages, the psychometric properties of the German self-report version have not yet been analyzed. Objective: This study examines the internal consistency, test-retest reliability, and construct validity of the German QoL-AD self-report scale. Methods: The sample included 30 patients suffering from mild to moderate Alzheimer’s disease or vascular dementia (19 females; mean age 77.3 years; mean Mini-Mental State Examination (MMSE) score 19.7 points). To determine test-retest reliability, the QoL-AD self-report scale was re-administered four to seven days apart. For construct validity analysis, the Dementia Quality of Life instrument (DQoL), Geriatric Depression Scale (GDS), MMSE, and an adapted short form of the Neuropsychiatric Inventory (NPI) were used. Results: The German QoL-AD self-report scale shows an internal consistency of α= 0.79 and a test-retest reliability of r = 0.75 (p < 0.01). Regarding construct validity, there was a significant positive correlation between the total scores of the QoL-AD and DQoL (r = 0.47, p < 0.05). The analysis revealed no significant correlations with the GDS or the adapted NPI. No association could be observed between the QoL-AD and the MMSE (r = 0.01), confirming divergent validity. Conclusion: The results indicate that the German QoL-AD self-report scale is a suitable instrument for assessing QoL in patients suffering from mild to moderate dementia, thus supporting its use in clinical practice and research.

Test Retest Reliability

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.

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.

Test Retest Reliability

Abstract The majority of studies on mental health in deaf and hard-of-hearing (DHH) children report a higher level of mental health problems. Inconsistencies in reports of prevalence of mental health problems have been found to be related to a number of factors such as language skills, cognitive ability, heterogeneous samples as well as validity problems caused by using written measures designed for typically hearing children. This study evaluates the psychometric properties of the self-report version of the Strengths and Difficulties Questionnaire (SDQ) in Norwegian Sign Language (NSL; SDQ-NSL) and in written Norwegian (SDQ-NOR). Forty-nine DHH children completed the SDQ-NSL as well as the SDQ-NOR in randomized order and their parents completed the parent version of the SDQ-NOR and a questionnaire on hearing and language-related information. Internal consistency was examined using Dillon–Goldstein’s rho, test–retest reliability using intraclass correlations, construct validity by confirmatory factor analysis (CFA), and partial least squares structural equation modeling. Internal consistency and test–retest reliability were established as acceptable to good. CFA resulted in a best fit for the proposed five-factor model for both versions, although not all fit indices reached acceptable levels. The reliability and validity of the SDQ-NSL seem promising even though the validation was based on a small sample size.

BackgroundPerceived ability or confidence plays an important role in determining function and behavior. The modified Gait Efficacy Scale (mGES) is a 10-item self-report measure used to assess walking confidence under challenging everyday circumstances.ObjectiveThe purpose of this study was to determine the reliability, internal consistency, and validity of the mGES as a measure of gait in older adults.DesignThis was a cross-sectional study.MethodsParticipants were 102 community-dwelling older adults (mean [±SD] age=78.6±6.1 years) who were independent in ambulation with or without an assistive device. Participants were assessed using the mGES and measures of confidence and fear, measures of function and disability, and performance-based measures of mobility. In a subsample (n=26), the mGES was administered twice within a 1-month period to establish test-retest reliability through the intraclass correlation coefficient (ICC [2,1]). The standard error of measure (SEM) was determined from the ICC and standard deviation. The Cronbach α value was calculated to determine internal consistency. To establish the validity of the mGES, the Spearman rank order correlation coefficient was used to examine the association with measures of confidence, fear, gait, and physical function and disability.ResultsThe mGES demonstrated test-retest reliability within the 1-month period (ICC=.93, 95% confidence interval=.85, .97). The SEM of the mGES was 5.23. The mGES was internally consistent across the 10 items (Cronbach α=.94). The mGES was related to measures of confidence and fear (r=.54–.88), function and disability (Late-Life Function and Disability Instrument, r=.32–.88), and performance-based mobility (r=.38–.64).LimitationsThis study examined only community-dwelling older adults. The results, therefore, should not be generalized to other patient populations.ConclusionThe mGES is a reliable and valid measure of confidence in walking among community-dwelling older adults.

Background There is little evidence for the measurement properties of instruments commonly used for women with pelvic girdle pain. Objective The aim of this study was to examine the internal consistency, test-retest reliability, and construct validity of instruments used for women with pelvic girdle pain. Design This was a cross-sectional methodology study, including test-retest reliability assessment. Methods Women with pelvic girdle pain in pregnancy and after delivery participated in a postal survey that included the Pelvic Girdle Questionnaire (PGQ), Oswestry Disability Index (ODI), Disability Rating Index (DRI), Fear-Avoidance Beliefs Questionnaire (FABQ), Pain Catastrophizing Scale (PCS), and 8-item version of the Medical Outcomes Study 36-Item Short-Form Health Survey questionnaire (SF-36). Test-retest reliability was assessed with a random subsample 1 week later. Internal consistency was assessed with the Cronbach alpha, and test-retest reliability was assessed with the intraclass correlation coefficient (ICC) and minimal detectable change (MDC). Construct validity based on hypotheses was assessed by correlation analysis. Discriminant validity was assessed with the area under the receiver operating characteristic curve. Results All participants responded to the main (N=87) and test-retest (n=42) surveys. Cronbach alpha values ranged from .88 to .94, and ICCs ranged from .78 to .94. The MDC at the individual level constituted about 7% to 14% of total scores for the 8-item version of the SF-36, ODI, and PGQ activity subscale; about 18% to 22% for the DRI, PGQ symptom subscale, and PCS; and about 25% for the FABQ. Hypotheses were mostly confirmed by correlations between the instruments. The PGQ was the only instrument that significantly discriminated participants who were pregnant from participants who were not pregnant as well as pain locations. Limitations A comparison of responsiveness to change of the various instruments used in this study was not undertaken, but will be carried out in a future study. Conclusions Self-report instruments for assessing health showed good internal consistency, test-retest reliability, and construct validity for women with pelvic girdle pain. The PGQ was the only instrument with satisfactory discriminant validity, thus, it is recommended for evaluating symptoms and disability in patients with pelvic girdle pain.

Previous surveys have indicated that the majority of Indonesian children have poor oral health. However, scant information is available on children’s oral health related quality of life (OHRQoL). The purpose of this study was to assess reliability as well as discriminant and convergent validity of Child Oral Health Impact Profile-Short Form 19 (COHIP-SF 19) Indonesian version. Methods: The Indonesian version of COHIP-SF 19 was developed according to the guidelines for the cross-cultural adaptation process. The instrument was tested among 529 children between 12 – 15 years old who were randomly selected from six junior high schools in Jakarta. The psychometric testing included internal consistency reliability, test-retest reliability, discriminant validity, and convergent validity. Results: Mean age of the participants was 13.3±0.9 years and 54% of the participants were female. The mean COHIP-SF 19 score was 57.8±8.8 and the median was 58 (range 27 – 75). The internal consistency and test-retest reliability was excellent for COHIP-SF 19 score with Chronbach’s alpha 0.83 and intra-class correlation coefficient 0.81. Children with active decay, untreated caries with pulpal involvement, and gingivitis had significantly lower COHIP-SF 19 scores (p-value ≤ 0.030). Correlation between COHIP-SF 19 score, subscale scores and clinical severity as well as self-rated general or oral health were very low to low (rs = 0.04 – 0.27, p-value ≤ 0.028), after adjustment for children’s age and gender. Conclusions: The Indonesian version of COHIP-SF 19 was successfully developed to be used as an OHRQoL instrument for Indonesian school-age children. The internal consistency, test-retest reliability, discriminant validity, and convergent validity of COHIP-SF 19 Indonesian version were confirmed

Test Retest Reliability

The internal consistency, test-retest reliability, and predictive validity of the Iowa Personality Disorder Screen (IPDS) as a screening instrument for personality disorders (PDs) were studied in 195 Dutch psychiatric outpatients, using the SCID-II as the gold standard. All patients completed a self-administered version of the IPDS. Internal consistency was moderate (0.64), and the test-retest reliability was good (0.87). According to the SCID-II, 97 patients (50%) had at least one personality disorder (PD). The IPDS correctly classified 81.0 percent of all participants in the category PD present/absent. The sensitivity and specificity were 77% and 88%, respectively. Positive and negative predictive values were 83% and 79%. Test-retest reliability after a 2-week interval was 0.87. These results are comparable with those reported in earlier studies with respect to the interview version of the IPDS and more promising than previously reported results obtained with a self-report version of the IPDS. Therefore, it is concluded that a self-report version of the IPDS may be useful as a screening measure for determining the presence/absence of PD in a population of psychiatric outpatients.

Oxford Happiness Questionnaire

The Oxford Happiness Questionnaire short-form (Hills & Argyle, 2002) is an 8-item measure of happiness. This study evaluated the internal consistency reliability and test-retest reliability of the Oxford Happiness Questionnaire short-form among 55 Northern Irish undergraduate university students who completed the measure on two occasions separated by two weeks. Internal consistency of the measure was satisfactory at both Time 1 (alpha = .62) and Time 2 (alpha = .58). Stability across the two administrations was satisfactory (r = .69), and there was no significant change between Time 1 (M = 34.5, SD = 5.4) and Time 2 (M = 34.6, SD = 5.2). These data support the internal consistency reliability and short-term test-retest reliability of the Oxford Happiness Questionnaire short-form.
