Performance Scale

The WISC-R Performance Scale was administered to 59 prelingually deaf children; The internal consistency reliability of four of the subtests and the Performance IQ were assessed and found to be similar to the reliability reported by Wechsler (1974) with the standardization sample. Two aspects of criterion-related validity were computed. Concurrent validity as demonstrated by the correlation with the Hiskey-Nebraska Test of Learning Aptitude was found to be adequate. Predictive validity as defined by the correlation with achievement test results was also computed. Statistically significant correlations were found for six of the eight achievement areas. Implications for use are discussed.

Premature Infant Pain Profile

Abstract Objectives:To verify the Correlation between the Neonatal Infant Pain Scale (NIPS) and Premature Infant Pain Profile – Revised (PIPP-R), the internal consistency of each scale, and assess the reliability between evaluators in the assessment of pain during the aspiration procedure in premature newborns. Methods: an observational, prospective study. Participated in the study, 50 infants who met the following criteria for inclusion: Newborn (NB) preterm (GA> 26 weeks and <36 weeks and five days) with low birth weight (<2500 g), hemodynamically stable, with minimal sedation or without sedation or mechanical ventilation in CPAP or catheter nose of O2 or the air environment that needed to perform the procedure of vacuum in the period of hospitalization. The evaluation of the newborns occurred during three different aspiration procedures; aspiration 1 (no intervention), aspiration 2 (use of gentle touch), and aspiration 3 (use of sucrose). They have applied two evaluation instruments, NIPS and PIPP-R. that Cronbach's alpha determined the internal consistency, reliability between evaluators by the coefficient of Correlation intraclass, validity competitor by Spearman test. Results: Internal Consistency was high for NIPS (r= 0.824) and moderate for PIPP-R (0.655). Reliability between raters was high respectively in the three conditions 0.991; 0.987; 0.993 on the NIPS scale and 0.997; 0.986; 0.977 on the PIPP-R scale. One observed concurrent validity Only in the first aspiration. Conclusion: the NIPS seems to have a better utility clinic than PIPP-R; however, the two scales showed good reliability among the evaluators, and internal consistency, being a good choice for evaluation of pain during the procedure of aspiration.

Item Functioning

This study looked into differentially functioning items in a Chemistry Achievement Test. It also<br />examined the effect of eliminating differentially functioning items on the content and concurrent validity,<br />and internal consistency reliability of the test. Test scores of two hundred junior high school students<br />matched on school type were subjected to Differential Item Functioning (DIF) analysis. One hundred<br />students came from a public school, while the other 100 were private school examinees. The<br />descriptive-comparative research design utilizing differential item functioning analysis and validity and<br />reliability analysis was employed. The Chi-Square, Distractor Response Analysis, Logistic Regression,<br />and the Mantel-Haenszel Statistic were the methods used in the DIF analysis. A six-point scale ranging<br />from inadequate to adequate was used to assess the content validity of the test. Pearson r was used in<br />the concurrent validity analysis. The KR-20 formula was used for estimating the internal consistency<br />reliability of the test. The findings revealed the presence of differentially functioning items between the<br />public and private school examinees. The DIF methods differed in the number of differentially<br />functioning items identified. However, there was a high degree of correspondence between the Logistic<br />Regression and Mantel-Haenszel Statistic. After the elimination of the differentially functioning items,<br />the content and the concurrent validity, and the internal consistency reliability differed per DIF method<br />used. The content validity of the test differed ranging from slightly adequate to moderately adequate in<br />the number of items retained. The concurrent validity of the test also differed but all were positive and<br />indicate moderate relationship between the examinees’ test scores and their GPA in Science III.<br />Likewise, the internal consistency reliability of the test differed. The more differentially functioning<br />items eliminated, the lesser was the content and concurrent validity, and internal consistency reliability<br />of the test becomes. Elimination of differentially functioning items diminishes content and concurrent<br />validity, and internal consistency reliability, but could be use as basis in enhancing content, concurrent<br />as well as internal consistency reliability by replacing eliminated DIF items.

This study was designed to evaluate a modification of the Interpersonal Relationship Scale and to establish subscales representing dimensions of intimacy (N = 356). The initial self-report scale was tested for internal consistency reliability. Next, subscales were identified using principal components factoring with varimax rotation. Internal consistency reliability and concurrent validity of the modified over-all scale and subscales were examined. The modified scale and subscales provided reliable and valid measures of the quality of interpersonal relationships in young adults.

The Kansas Marital Satisfaction Scale was administered by survey to 51 wives between the ages of 32 and 71 yr. Further support for the internal consistency reliability of the scale (α = 0.92) was obtained, and patterns of differences between the item means paralleled previous research. Evidence was found for the concurrent validity of the scale, which correlated significantly with six of seven items from the satisfaction subscale of Spanier's Dyadic Adjustment Scale.

BACKGROUND Engagement emerges as a predictor for the effectiveness of digital health interventions. However, a shared understanding of engagement is missing. Therefore, a new scale has been developed that proposes a clear definition and creates a tool to measure it. The TWente Engagement with Ehealth Technologies Scale (TWEETS) is based on a systematic review and interviews with engaged health app users. It defines engagement as a combination of behavior, cognition, and affect. OBJECTIVE This paper aims to evaluate the psychometric properties of the TWEETS. In addition, a comparison is made with the experiential part of the Digital Behavior Change Intervention Engagement Scale (DBCI-ES-Ex), a scale that showed some issues in previous psychometric analyses. METHODS In this study, 288 participants were asked to use any step counter app on their smartphones for 2 weeks. They completed online questionnaires at 4 time points: T0=baseline, T1=after 1 day, T2=1 week, and T3=2 weeks. At T0, demographics and personality (conscientiousness and intellect/imagination) were assessed; at T1-T3, engagement, involvement, enjoyment, subjective usage, and perceived behavior change were included as measures that are theoretically related to our definition of engagement. Analyses focused on internal consistency, reliability, and the convergent, divergent, and predictive validity of both engagement scales. Convergent validity was assessed by correlating the engagement scales with involvement, enjoyment, and subjective usage; divergent validity was assessed by correlating the engagement scales with personality; and predictive validity was assessed by regression analyses using engagement to predict perceived behavior change at later time points. RESULTS The Cronbach alpha values of the TWEETS were .86, .86, and .87 on T1, T2, and T3, respectively. Exploratory factor analyses indicated that a 1-factor structure best fits the data. The TWEETS is moderately to strongly correlated with involvement and enjoyment (theoretically related to cognitive and affective engagement, respectively; <i>P</i>&lt;.001). Correlations between the TWEETS and frequency of use were nonsignificant or small, and differences between adherers and nonadherers on the TWEETS were significant (<i>P</i>&lt;.001). Correlations between personality and the TWEETS were nonsignificant. The TWEETS at T1 was predictive of perceived behavior change at T3, with an explained variance of 16%. The psychometric properties of the TWEETS and the DBCI-ES-Ex seemed comparable in some aspects (eg, internal consistency), and in other aspects, the TWEETS seemed somewhat superior (divergent and predictive validity). CONCLUSIONS The TWEETS performs quite well as an engagement measure with high internal consistency, reasonable test-retest reliability and convergent validity, good divergent validity, and reasonable predictive validity. As the psychometric quality of a scale is a reflection of how closely a scale matches the conceptualization of a concept, this paper is also an attempt to conceptualize and define engagement as a unique concept, providing a first step toward an acceptable standard of defining and measuring engagement.

Abstract Background: Adherence to antiretroviral therapy is critical to the achievement of the third target of the UNAIDS Fast-Track Initiative goals of 2020-2030. Reliable, valid and accurate measurement of adherence are important for correct assessment of adherence and in predicting the efficacy of ART. The Simplified Medication Adherence Questionnaire is a six-item scale which assesses the perception of persons living with HIV about their adherence to ART. Despite recent widespread use, its measurement properties have yet to be carefully documented beyond the original study in Spain. The objective of this paper was to conduct internal consistency reliability, concurrent validity and measurement invariance tests for the SMAQ. Methods: HIV-positive women who were receiving ART services from 51 service providers in two sub-cities of Addis Ababa, Ethiopia completed the SMAQ in a HIV treatment referral network study between 2011 and 2012. Two cross-sections of 402 and 524 female patients of reproductive age, respectively, from the two sub-cities were randomly selected and interviewed at baseline and follow-up. We used Cronbach’s coefficient alpha (α) to assess internal consistency reliability, Pearson product-moment correlation (r) to assess concurrent validity and multiple-group confirmatory factor analysis to analyze factorial structure and measurement invariance of the SMAQ. Results: All participants were female with a mean age of 33 (33.06-33.74; median: 34 years; range 18-45 years. Cronbach’s alphas for the six items of the SMAQ were 0.66, 0.68, 0.75 and 0.75 for T1 control, T1 intervention, T2 control, and T2 intervention groups, respectively. Pearson correlation coefficients were 0.78, 0.49, 0.52, 0.48, 0.76 and 0.80 for items 1 to 6, respectively, between T1 compared to T2. We found invariance for factor loadings, observed item intercepts and factor variances, also known as strong measurement invariance, when we compared latent adherence levels between and across patient-groups. Conclusions: Our results show that the six-item SMAQ scale has adequate reliability and validity indices for this sample, in addition to being invariant across comparison groups. The findings of this study strengthen the evidence in support of the increasing use of SMAQ by interventionists and researchers to examine, pool and compare adherence scores across groups and time periods.

Capitalization is an interpersonal process where one shares personal positive events with others and receives benefits beyond that event's effect. The response a capitalizer perceives from the recipient determines the success of this process. The Perceived Responses to Capitalization Attempts Scale (PRCAS) is an English-language measure used to assess a capitalizer's perception of a recipient's responses. We tested the factor structure, internal consistency reliability, and concurrent validity of the Chinese version of the PRCAS with a sample of 1,213 Chinese college students. Factor analyses replicated the 4-factor model of active–constructive response, passive–constructive response, active–destructive response, and passive–destructive response. All subscales possessed satisfactory internal consistency and evidence for concurrent validity with measures of feeling, flourishing, self-esteem, and mental health symptoms. We also assessed the test–retest stability of the PRCAS with a separate sample of 119 Chinese college students, and found that the subscales possessed low test–retest reliability. Therefore, the Chinese PRCAS possessed acceptable psychometric properties.

Gurin's modification of the Health Opinion Survey was completed by 178 medical students, aged 19 to 25 yr., and 241 secondary school pupils, aged 9 to 19 yr. Internal consistency reliability measured by coefficient alpha was .77 and .79, respectively, on the two ratings. The mean of the correlation of each item with the remaining items was .34 for each rating. These findings show that the items on the instrument have much in common, which implies that a single trait may be measured by the Health Opinion Survey.
