Classification Project

To add evidence of the validity of the Children's Behavioral Classification Inventory, the responses of parents and teachers were compared on a set of 110 items of the inventory which describe behaviors equally observable to both groups. The two sets of data were subjected in Phase I to principal components analysis to extract two factors in each case which were compared by means of the Ahmavaara transformation and found to be highly comparable. In Phase II, predictions were made from factor weights of 36 items measuring six factors in the original standardization of the inventory to both sets of respondents' data by means of confirmatory factor analysis. The formal indices of comparability were not generally in acceptable ranges; however, substantively the six factors were definitely replicated in the two samples.

Trust Scale

The purpose of this study was to examine the psychometric properties of the Specific Interpersonal Trust scale of Johnson-George and Swap in Korean samples as a part of the process of providing an exemplary tool for intercultural studies of trust. A translated version of the original scale was administered to 337 university students (157 males, 180 females) in Seoul, Korea. Data were subjected to a principal components analysis and a confirmatory factor analysis. In principal components analysis for the Korean sample ( n = 167), three factors were identified and labeled: Overall Trust (Cronbach α=.89), Emotional Trust (Cronbach α = .88), and Reliableness (Cronbach α=.84). A confirmatory factor analysis ( n=170) showed that the three-factor model was valid for the sample (χ2/ df= 1.78, RMR=.06, RMSEA = .07, TLI=.92, CFI=.93). Internal consistency reliability and factorial validity were satisfactory in the case of the Korean sample. The Korean version of the Specific Interpersonal Trust Scale made good use of three factors of trust and appeared to be valid without sex differences, while the original scale distinguished the Males subscale from the Females subscale. Implications and limitations of this study were discussed.

The literature suggests limitations to Dickman’s dysfunctional impulsivity (DI) scale. These concerns are centered on the measurement properties of this scale and on its reliance on student samples. To address these criticisms, the DI was administered to a random adult sample (n = 649, mean age 43.83 ± 13.46 years), 13% of whom were university educated. Confirmatory factor analysis (CFA) did not support the fit of the posited 12-item DI scale. The full sample was randomly divided. Principal components analysis was applied to one sample (n = 328), resulting in a 9-item model. This new model was then replicated using CFA in the second sample (n = 321). Cronbach’s α for the 9-item model was 0.84 and item-total correlations were > 0.39. The 30th and 70th percentile scores from the DI distribution of scores were used to categorize participants with low and high DI. The high-DI group was associated with significantly more driving distractions and lane crossings.

AbstractSome studies have concluded there is a relationship between perceived self-efficacy and behaviors that prevent HIV transmission. This paper presents the construction and validation of the latex barrier use self-efficacy scale (LBSS), which 480 participants filled out. Exploratory factor analysis yielded two components: positive expectations of self-efficacy (ES-POS) and negative expectations of self-efficacy (ES-NEG), which together accounted for 65.59% of total variance. That structure was later verified through confirmatory factor analysis. Internal consistency was .80 for the total scale, and .78 for each of the two factors. Moreover, the instrument had adequate convergent validity and was positively related with condom use self-efficacy, attitudes toward condom and latex barrier use, and ability to refuse sex if the partner refuses to use preventive methods. In conclusion, this instrument is a useful measure of self-efficacy in latex barrier use.

Objective: The purposes of this investigation were to determine whether the temporal onsets of swallow events segment into oral and pharyngeal phases, to test the interdependence of temporal onsets of swallow events, and to determine the influence of age on total swallow duration. Study Design and Setting: The onsets of swallowing and respiratory measures were studied in 76 healthy normal individuals. Results: Confirmatory factor analysis revealed a 2-factor solution but did not support the hypothesized 2-phase structure (ie, oral and pharyngeal). Two of the onsets, apnea onset and apnea offset, formed a single factor that explained 12.6% of the variation among the 11 onset times. The other 9 onsets formed a second factor that explained 66.4% of the variation. Age accounted for modest variation in total swallow duration. Conclusions: The two factors, oropharyngeal and respiratory, explained 79% of the variation among the 11 onset times. Significance: This finding speaks to the overlap between the initiation of oral and pharyngeal components of swallowing in adults and highlights the artificiality of separating the swallowing continuum into isolated phases.

The purpose of this study was to develop a rating scale that can be used to evaluate behavior patterns of the organization people pattern of preservice teachers (PSTs). By reviewing the related literature on people patterns, a preliminary scale of 38 items with a five-points likert type was prepared. The number of items was reduced to 29 after obtaining expert opinions and was administered to 620 PSTs. As the results of the exploratory and confirmatory factor analysis, unlike two factors: structurist and free spirits behavior patterns, in the theory, we obtained the final scale of 15 items consisting of three factors: planners, solution-oriented and prescriptive behavior patterns. The related Cronbach Alpha value was found to be .830 for all the items. We identified that behavior patterns rating scale of the organization people pattern can be confidently applied to evaluate behavior patterns. Moreover, in this study, we obtained a contradiction between practice and theory. Thus, we provided a new idea related to behavior patterns of the organization people pattern.

Patient Enablement

Background: The purpose of our study was to develop and psychometrically test a German-language survey instrument that measures patient enablement generically and in greater detail than previous instruments. Methods: A multidisciplinary team developed 13 items to capture individual aspects of patient enablement (PEN-13). A pre-test with 26 subjects was followed by a random sample survey of N = 1168 subjects. An exploratory factor analysis was conducted in a random split-half sample of the data to explore PEN-13’s factor structure; a confirmatory factor analysis was conducted in the validation sample. The internal consistency of the factors was evaluated using Cronbach’s alpha, PEN-13’s construct validity was checked by means of additional hypothesis testing. Results: The two factors self-management and patient-practitioner interaction, detected in the exploratory analysis, were confirmed with a few modifications in the confirmatory factor analysis, with the comparative fit index (CFI) amounting to 0.903. The Cronbach’s alpha values of those two factors amounted to α = 0.90 and α = 0.82, respectively. The correlations of the PEN-13 score with the ’general self-efficacy’ and ’health literacy’ (HLS-EU-Q16) scores further confirmed its construct validity; the respective correlation coefficients amounted to 0.57 and 0.60. Conclusion: The German version of the survey instrument Patient Enablement Scale—13 items (PEN-13) shows acceptable psychometric properties. Practical implications: PEN-13 seems particularly suitable for health services research purposes. We recommend checking the results in another sample as well as evaluating its responsiveness to enablement-enhancing interventions.

Multiple Regression Technique

The factor analytic model of the practitioner-oriented Opinions About People (OAP) was tested with a population of gerontological practitioners (N = 558). A confirmatory factor analysis was performed to ascertain the degree-of-fit between these data and the published OAP factor model. After results supported the hypothesis that the two samples differed, a second factor analysis was designed to yield estimates of communalities by a least squares multiple regression technique. This analysis eliminated nine items not warranting inclusion in the instrument, redistributed the factors, and brought out a completely new factor. Finally, to test the hypothesis that attitudes toward aging and the aged are uncorrected, a third analysis was performed in which the six scales of the oblique solution were refactored. The resulting higher order dimensions tended to support this hypothesis.

Objective: Understanding the construct of hopelessness in the context of a life-threatening or terminal illness is a complex and challenging undertaking. The objective of this study was to examine the construct of hopelessness in patients with advanced AIDS by examining the structure of the Beck Hopelessness Scale in this specific population.Methods: For the past three decades, the primary measure used to study hopelessness in a variety of populations has been the Beck Hopelessness Scale. Several factor analytic studies have been published using this scale, with studies of nonclinical samples typically describing a two-factor model (optimism and pessimism), whereas clinical samples have consistently generated a third factor (lack of motivation to make changes). We used confirmatory factor analysis to analyze two data sets in patients with AIDS.Results: Confirmatory factor analysis of the Beck Hopelessness Scale in two samples of patients with far advanced AIDS revealed a clear superiority for a three-factor model.Significance of results: The Beck Hopelessness Scale has unique characteristics when applied to a terminally ill population. The implications of these results for studies of terminal illness are discussed.
