Test Retest Reliability

Anger is a natural emotion which involves a strong uncomfortable and emotional response to a perceived provocation. Mild anger motivates an individual to take appropriate action in many areas of life. When anger goes beyond an optimal level it not only causes physical harm and psychological harm but it also intrudes with achievement of higher level of consciousness. In order to measure and compare anger among individuals a need for construction of anger scale was realized. Therefore, the researcher tried to construct a scale which could measure anger among individuals. Items with low coefficient of correlation (r= .14 or less) were discarded and finally 30 items with r= .15 to .67 were retained in the final test. Thus, internal consistency of Anger Scale was established. Test Retest Reliability of the scale (with a time gap of 25 days) came out to be .86. For establishing criterion validity, scores on Anger Scale were correlated with scores of well being. High negative coefficient of correlation of anger scores with well being indicated that higher the anger lower is the level of well being among individuals. The coefficient of correlation was found to be -.85. Again criterion validity was supported by significant positive relationship between egotism and anger also. The coefficient of correlation was .65. It shows that as the egotism increases the level of anger increases and vice versa. Validity of anger scale was established with the help of scores on EEG. The mean alpha waves of higher anger group were found to decrease significantly when subjects’ anger was experimentally aroused. On the other hand Mean EEG scores of low anger group as measured by the Anger Scale did not change significantly. Thus, the validity of anger scale was experimentally established.

Tremor is a common symptom of multiple sclerosis (MS) that has debilitating effects on occupational performance and well-being. Tremor is complex, and a valid and reliable assessment tool that takes a multidimensional approach is needed to guide intervention decisions. A new assessment instrument, the Multidimensional Assessment of Tremor (MAT), was designed to measure the severity and functional impact of tremor in people with MS. This study was conducted to introduce this new tool and examine its reliability, validity, and clinical utility. Two clinicians tested the MAT and completed a questionnaire on its clinical utility. During an initial visit, 10 study participants with MS were administered the MAT, which was independently scored by two researchers to determine its inter-rater reliability. Four other tools commonly used to assess tremor were also administered to evaluate the MAT's criterion validity. During a second visit, the MAT was administered a second time to ascertain its test-retest reliability. Study participants demonstrated mild-to-severe tremor with marked functional difficulties. The MAT's inter-rater reliability and test-retest reliability were excellent, while its criterion validity ranged from poor to good. The clinicians, participants, and researchers found the clinical utility of the tool to be good. The MAT offers therapists a clinically useful, evidence-based, and multidimensional tool for evaluating tremor in MS.

For the purpose of the development of novel approaches during the commission stage, the hygienic assessment of conditions of training in specially constructed innovative building of SKOLKOVO International Gymnasium was performed. Hygienic examination of innovative architectural and planning solutions, learning conditions and hygienic modeling of the optimal placement of furniture and equipment in multi-faceted educational facilities with panoramic glazing made it possible to predict the provision of the gymnasium with an optimal level of sanitary and epidemiological well-being of students. This is achieved by the innovative layout of the gymnasium building and its territory. Hygienic specification of zoning of both buildings and premises of the educational institution, include the requirements to satisfy the hygienic criteria on children education, motor activity, organization of proper nutrition, and using the building as a center for family leisure. Hygienic modeling of educational furniture and equipment provides optimal conditions (viewing angle) for visual work of students in all multifaceted classes. The obtained data are the basis for amendments to the state sanitary and epidemiological rules and regulations in the field of organization of education and upbringing of children.

Abstract Background People are living longer than ever before. However, with living longer comes increased problems that negatively impact on quality of life and the quality of death. Tools are needed to help individuals assess whether they are practicing the best attitudes and behaviors that are associated with a future long life, high quality of life, high quality of death and a satisfying post-death legacy. The purpose of paper is to describe the process we used to develop a novel questionnaire (“Preparedness for the Future Questionnaire™ or Prep FQ”) and to define its psychometric properties. Methods Using a multi-step development procedure, items were generated, for the new questionnaire after which the psychometric properties were tested with a heterogeneous sample of 502 Canadians. Using an online polling panel, respondents were asked to complete demographic questions as well as the Prep-FQ, Global Rating of Life Satisfaction, the Keyes Psychological Well-Being scale and the Short-Form 12. Results The final version of the questionnaire contains 34 items in 8 distinct domains (“Medico-legal”, “Social”, “Psychological Well-being”, “Planning”, “Enrichment”, “Positive Health Behaviors”, “Negative Health Behaviors”, and “Late-life Planning”). We observed minimum missing data and good usage of all response options. The average overall Prep FQ score is 51.2 (SD = 13.3). The Cronbach alphas assessing internal reliability for the Prep FQ domains ranged from 0.33 to 0.88. The intra-class correlation coefficient (ICC) used to assess the test–retest reliability had an overall score of 0.87. For the purposes of establishing construct validity, all the pre-specified relationships between Prep FQ and the other questionnaires were met. Conclusion Analyses of this novel measure offered support for its face validity, construct validity, test–retest reliability, and internal consistency. With the development of this useful and valid scale, future research can utilize this measure to engage people in the process of comprehensively assessing and improving their state of preparedness for the future, tracking their progress along the way. Ultimately, this program of research aims to improve the quality and quantity of peoples live by helping them ‘think ahead’ and ‘plan ahead’ on the aspects of their daily life that matter to their future.

BACKGROUND To assess whether commercial-grade activity monitors are appropriate for measuring step counts in older adults, it is essential to evaluate their measurement properties in this population. OBJECTIVE This study aimed to evaluate test-retest reliability and criterion validity of step counting in older adults with self-reported intact and limited mobility from 6 commercial-grade activity monitors: Fitbit Charge, Fitbit One, Garmin vívofit 2, Jawbone UP2, Misfit Shine, and New-Lifestyles NL-1000. METHODS For test-retest reliability, participants completed two 100-step overground walks at a usual pace while wearing all monitors. We tested the effects of the activity monitor and mobility status on the absolute difference in step count error (%) and computed the standard error of measurement (SEM) between repeat trials. To assess criterion validity, participants completed two 400-meter overground walks at a usual pace while wearing all monitors. The first walk was continuous; the second walk incorporated interruptions to mimic the conditions of daily walking. Criterion step counts were from the researcher tally count. We estimated the effects of the activity monitor, mobility status, and walk interruptions on step count error (%). We also generated Bland-Altman plots and conducted equivalence tests. RESULTS A total of 36 individuals participated (n=20 intact mobility and n=16 limited mobility; 19/36, 53% female) with a mean age of 71.4 (SD 4.7) years and BMI of 29.4 (SD 5.9) kg/m<sup>2</sup>. Considering test-retest reliability, there was an effect of the activity monitor (<i>P</i>&lt;.001). The Fitbit One (1.0%, 95% CI 0.6% to 1.3%), the New-Lifestyles NL-1000 (2.6%, 95% CI 1.3% to 3.9%), and the Garmin vívofit 2 (6.0%, 95 CI 3.2% to 8.8%) had the smallest mean absolute differences in step count errors. The SEM values ranged from 1.0% (Fitbit One) to 23.5% (Jawbone UP2). Regarding criterion validity, all monitors undercounted the steps. Step count error was affected by the activity monitor (<i>P</i>&lt;.001) and walk interruptions (<i>P</i>=.02). Three monitors had small mean step count errors: Misfit Shine (−1.3%, 95% CI −19.5% to 16.8%), Fitbit One (−2.1%, 95% CI −6.1% to 2.0%), and New-Lifestyles NL-1000 (−4.3%, 95 CI −18.9% to 10.3%). Mean step count error was larger during interrupted walking than continuous walking (−5.5% vs −3.6%; <i>P</i>=.02). Bland-Altman plots illustrated nonsystematic bias and small limits of agreement for Fitbit One and Jawbone UP2. Mean step count error lay within an equivalence bound of ±5% for Fitbit One (<i>P</i>&lt;.001) and Misfit Shine (<i>P</i>=.001). CONCLUSIONS Test-retest reliability and criterion validity of step counting varied across 6 consumer-grade activity monitors worn by older adults with self-reported intact and limited mobility. Walk interruptions increased the step count error for all monitors, whereas mobility status did not affect the step count error. The hip-worn Fitbit One was the only monitor with high test-retest reliability and criterion validity.

Test Retest Reliability

There is a paucity of validated mental health measures for assessing psychological well-being among HIV-affected youth. We sought to explore the psychometric properties and validity of the Achenbach Youth Self-Report and Child Posttraumatic Stress Disorder Symptom Scale among orphans and vulnerable children (OVC) living in Lusaka, Zambia. These scales were administered to 210 OVC aged 13 to 17 years via audio computer-assisted self-interview. Confirmatory factor analysis was used to assess scale structure, Cronbach’s alpha for internal consistency, and correlations between scales related to mental or psychosocial health for construct validity. A known-groups validation was conducted using local identifications of youth with and without significant psychosocial problems, and test–retest reliability was assessed. Scales exhibited good internal reliability (α > .80), adequate criterion validity (area under the curve > .70), and moderate test–retest reliability (.62-.68). Findings support the utility of these symptom scales for identifying OVC experiencing significant psychosocial problems in Zambia.

BACKGROUND: Dyspnea, or difficult breathing, is common in patients receiving mechanical ventilation; however, dyspnea is not routinely or systematically measured. OBJECTIVE: The primary purpose of this methodological study was to evaluate the test-retest reliability of 5 dyspnea rating scales and the criterion validity of 4 dyspnea rating scales in patients receiving mechanical ventilation. The secondary purpose was to examine the correlations between each of these 5 rating scales and physiological measures of respiratory function. METHODS: The convenience sample consisted of 28 patients on mechanical ventilation during their hospitalization in the intensive care units of a large, inner-city hospital. Patients rated their dyspnea twice at 30-minute intervals on the visual analogue scale, the vertical analogue dyspnea scale, the modified Borg scale, the numerical scale, and the faces scale. Test-retest reliability was computed by using the intraclass correlation coefficient. Criterion validity was evaluated by using the Spearman rank-order correlation coefficient. RESULTS: The 5 rating scales had acceptable test-retest reliabilities, with intraclass correlation coefficients ranging from 0.81 to 0.97. Criterion validity of the 4 scales also was acceptable, with Spearman rank-order correlation coefficients from 0.76 to 0.96. The rating scales were not correlated with most of the physiological variables. At least half of the patients reported moderate to severe dyspnea. CONCLUSION: The scales showed acceptable reliability and validity, and they will be useful in quantifying dyspnea experienced by patients receiving mechanical ventilation. Further work is needed to evaluate the extent and the severity of dyspnea in such patients in order to evaluate the effectiveness of interventions.

Test Retest Reliability

Many schools attempt to identify and service students at risk for poor mental health outcomes within a multi-tiered system of support (MTSS). Universal screening within a MTSS requires technically adequate tools. The Social, Academic, and Emotional Behavior Risk Screener (SAEBRS) has been put forth as a technically adequate screener. Researchers have examined the factor structure, diagnostic accuracy, criterion validity, and internal consistency of SAEBRS data. However, previous research has not examined its temporal stability or replicated the criterion validity results with a racially/ethnically diverse urban elementary school sample. This study examined the test–retest reliability, convergent validity, and predictive validity of teacher-completed SAEBRS ratings with racially/ethnically diverse group students enrolled in first through fifth grade in an urban elementary school. Reliability analyses resulted in significant test–retest reliability coefficients across four weeks for all SAEBRS scales. Furthermore, nonsignificant paired samples t tests were observed with the exception of the third-grade Emotional subscale. Validity analyses yielded significant concurrent and predictive Pearson correlation coefficients between SAEBRS ratings, oral reading fluency, and office discipline referrals. Limitations and implications of the results are discussed.

Abstract Curiosity is commonly defined as “the desire for new information and experience.” While curiosity has been associated with numerous positive outcomes (e.g., improved well-being, better cognitive performance and longer life expectancy, some studies suggested that curiosity declined with age. However, very few studies actually attempt to examine why curiosity may be lower among older adults. Moreover, scholars disagreed on “why” people feel curious. According to the dual process theory (Spielberger & Starr, 1994), curiosity is induced by optimal level of uncertainty and anxiety with the desire to reduce these aversive feelings. However, the personal growth facilitation model (Kashdan, Rose, & Fincham, 2002) posits that people are curious intrinsically for one’s own growth, which is associated with positive affects. Therefore, the present study aims to examine age differences in the affective profile of feeling curious by comparing the momentary affective experience of curiosity between younger and older adults. In this study, we conducted a 2-week time-sampling study with 78 younger adults (age 19-29) and 79 older adults (age 60-85) from Hong Kong. Multilevel modeling analyses demonstrated a positive relationship between curiosity and positive emotions for both younger (β=.29, p&lt;.01) and older adults (β=.70, p&lt;.01). Interestingly, anxiousness was positively associated with younger adults’ curiosity (β=.09, p=.01) but not for older adults (β=.06, p=.29). Our study supported both theories, but suggested that one may be more dominant among older adults. These findings have important implications for future interventions to reduce anxiousness to encourage older adults to keep an open-minded attitude towards novelties.
