The purpose of this study was to create a valid and reliable instrument to evaluate theory-basedbeliefs towards physical activity among clergy members. Data were collected from 174 clergy that par-ticipated in a 15-item online and paper-based survey. Psychometric properties of the instrument includedconfirmatory factor analysis (construct validity), and cronbach’s alpha (internal consistency reliability).In addition, the stability (test-retest reliability) of each subscale was evaluated with a sub-sample of 30participants. Results show the instrument was both valid and reliable, and will be useful in future studiestargeting this population. Future implications are discussed.

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.

Brief Screening

The Khatena-Morse Multitalent Perception Inventory has two forms of 50 items each designed to identify leadership, music, art, and creative talent of people age 10 yr. and over. It was developed on the basis of previous research and hypotheses about these areas of talent reported and used by the first author in the construction of earlier records for assessment of talent. Most subjects can complete the inventory in 10 to 30 min. Scoring is done by counting affirmative responses; the total serves as a versatility index. Internal consistency, alternate forms, and test-retest reliability, and indices of validity indicate the inventory is promising as a brief screening device for multitalent presently defined as versatility.

Disability sports has become more popular since the last the five decades. The increase in participation will cause pressure among athletes to achieve optimum sports performances. Through proper nutrition, the athletes’ sports performance can be enhanced. The benefits of nutrition in sports performance among athletes can be attained if their level of nutritional knowledge and habits are identified. This paper intends to present the design of the questionnaires from previous literature and predicted questionnaire model for this study. This study aims to develop, a questionnaire that combines both nutritional knowledge and supplement habits among disabled athletes in Malaysia, to validate and determine the reliability of the developed questionnaire. Expert validation, test-retest reliability, and internal consistency reliability will be used in this study. In expert validation, seven experts in nutrition, dietetics and sports nutrition field will be involved, and the data will be measured using the content validity ratio (CVR). Pearson Correlation Coefficient and Cronbach Alpha will be applied to determine the internal consistency reliability and test-retest reliability in determining the reliability of the developed questionnaire. As a result, a valid and reliable questionnaire that combines both nutritional knowledge and supplement habits specifically for Malaysian disabled athletes will be established, thus optimizing the growth of Malaysia disability sports. However, this research has not completed yet.

BackgroundSelf-report measurement instruments are commonly used to screen for mental health disorders in Low and Middle-Income Countries (LMIC). The Western origins of most depression instruments may constitute a bias when used globally. Western measures based on the DSM, do not fully capture the expression of depression globally. We developed a self-report scale design to address this limitation, the International Depression Symptom Scale-General version (IDSS-G), based on empirical evidence of the signs and symptoms of depression reported across cultures. This paper describes the rationale and process of its development and the results of an initial test among a non-Western population.MethodsWe evaluated internal consistency reliability, test–retest reliability and inter-rater reliability of the IDSS-G in a sample N = 147 male and female attendees of primary health clinics in Yangon, Myanmar. For criterion validity, IDSS-G scores were compared with diagnosis by local psychiatrists using the Structured Clinical Interview for DSM (SCID). Construct validity was evaluated by investigating associations between the IDSS-G and the Patient Health Questionnaire (PHQ), impaired function, and suicidal ideation.ResultsThe IDSS-G showed high internal consistency reliability (α = 0.92), test–retest reliability (r = 0.87), and inter-rater reliability (ICC = 0.90). Strong correlations between the IDSS-G and PHQ-9, functioning, and suicidal ideation supported construct validity. Criterion validity was supported for use of the IDSS-G to identify people with a SCID diagnosed depressive disorder (major depression/dysthymia). The IDSS-G also demonstrated incremental validity by predicting functional impairment beyond that predicted by the PHQ-9. Results suggest that the IDSS-G accurately assesses depression in this population. Future testing in other populations will follow.

The purpose of this study was to identify the factor structure of the Child Oral and Motor Proficiency Scale (ChOMPS) and to evaluate the psychometric properties, including internal consistency reliability, test–retest reliability, and construct validity as measured by convergent and known-groups validity. Principal component analysis with varimax rotation conducted on responses from 364 parents of children between 6 months and 7 years of age identified four subscales: complex movement patterns, basic movement patterns, oral-motor coordination, and fundamental oral-motor skills. Acceptable internal consistency reliability (Cronbach’s α = .97) and test–retest reliability ( r = .98) were found. Convergent and known-groups validity were supported by significant associations between the ChOMPS and validation measures, as well as significant differences in the ChOMPS scores between children with and without feeding problems. The ChOMPS is a 63-item parent-report measure of eating, drinking, and related motor skills in children aged 6 months to 7 years with evidence of reliability and validity.

<p>The aim of this research is to develop the Interpersonal Attractiveness Scale and examine its validity and reliability. The sample of the study consisted of 1145 students from Sakarya University. In this study, construct validity, internal consistency, test-retest reliability, and item analysis of the scale were examined. As a result of factor analysis for construct validity, four factors have emerged which are named physical appearance, personal characteristics, the frequency of visual, and values. These subscales consist of 19 items and account for the 46% of the total variance. The internal consistency reliability coefficients were .77 for physical appearance, .74 for personal characteristics, .81 for the frequency of visual, and .74 for values. Findings also demonstrated that item-total correlations ranged from .40 to .72. Test-retest reliability coefficients were .38 and .60 for four subscales, respectively. The item-total correlations ranged from .40 to .72. According to these findings the Interpersonal Attractiveness Scale can be regarded as a valid and reliable instrument that could be used in the field of psychology.</p><p> </p><p><strong>Özet</strong></p><p>Bu araştırmanın amacı Kişilerarası Çekicilik Ölçeğini geliştirmek ve geçerlik, güvenirlik analizlerini yapmaktır.

Background and PurposeWhile nursing students' attitudes about research are generally positive, little is known about their attitudes toward education research. The purpose of this study was to test the psychometric properties of the newly developed Nursing Students' Attitudes toward Nursing Education Research Questionnaire (NSANERQ).MethodsThe 25-item NSANERQ was adapted from an existing tool measuring nursing students' attitudes toward nursing research. Content and construct validity, and internal consistency and test–retest reliability were evaluated. Content validity was assessed using a panel of five experts. Internal consistency reliability and construct validity were assessed in a sample of 156 senior, junior, and sophomore baccalaureate nursing students with a mean age of 20.55 years. A separate sample of 49 freshmen baccalaureate nursing students with a mean age of 18.35 years was used to assess test–retest reliability. Both samples were predominantly female, White, and non-Hispanic/non-Latino.ResultsThe NSANERQ demonstrated excellent content validity (S-CVI = 0.92), good internal consistency reliability (α = 0.88), and acceptable test–retest reliability (r = 0.71) over 2 weeks. Exploratory factor analysis resulted in a six-factor solution, which was confirmed through confirmatory factor analysis.ConclusionsThe NSANERQ is a valid and reliable instrument that can be used to measure students' attitudes toward nursing education research.

Test Retest Reliability

The literature contains a variety of assessment tools for measuring the skills of individuals with autism or other developmental delays, but most lack adequate empirical evidence supporting their reliability and validity. The current pilot study sought to examine the reliability of scores obtained from the Assessment of Basic Language and Learning Skills–Revised (ABLLS-R). Two forms of reliability were measured: internal consistency and test–retest reliability. Analyses using data obtained from neuro-typical children ( N = 50) yielded strong evidence of internal consistency and test–retest reliability. These preliminary findings suggest that the ABLLS-R can yield reliable scores.

Depressive Tendency

IntroductionOlder adults with depression resist accepting depression screening and seeking treatment due to stigmatization of mental disorders and little knowledge about depression. This study was undertaken to develop and determine the psychometrics of an instrument for assessing triggers of suicidal ideation among older outpatients.MethodParticipants were recruited from older outpatients of two hospitals in northern Taiwan. An initial 32-item Triggers of Suicidal Ideation Inventory (TSII) was developed, and its items were validated by experts in two runs of Delphi technique survey. After this TSII was pre-tested in 200 elderly outpatients, 12 items were retained. The 12-item TSII was examined by criterion validity, construct validity, internal consistency reliability, and test-retest reliability.ResultsTSII scores were significantly and positively correlated with the Beck Scale for Suicide Ideation (r = 0.45, P < 0.01), and UCLA Loneliness scores (r = 0.55, P < 0.01), indicating satisfied criterion validity. Participants with depressive tendency tended to have higher TSII scores than participants with no depressive tendency (t = 8.62, P < 0.01), indicating good construct validity. Cronbach's α and the intraclass correlation coefficient for the TSII were 0.70 and 0.99 respectively, indicating acceptable internal consistency reliability and excellent test-retest reliability. Receiver operating characteristic analysis revealed that the area under the curve was 0.83, indicating excellent ability to detect triggers of suicidal ideation. With a cutoff point of 2, the sensitivity and specify were 0.86 and 0.67, respectively.ConclusionsThe TSII can be completed in 5 minutes and is perceived as easy to complete. Moreover, the inventory yielded highly acceptable parameters of validity and reliability.Disclosure of interestThe authors have not supplied their declaration of competing interest.
