Addenbrooke’S Cognitive Examination

Background: The Addenbrooke's Cognitive Examination (ACE) is used to measure cognition across a range of domains in dementia. Identifying the order in which cognitive decline occurs across items, and whether this varies between dementia aetiologies could add more information to subdomain scores. Method: ACE-Revised data from 350 patients were split into three groups: Alzheimer's type (n = 131), predominantly frontal (n = 119) and other frontotemporal lobe degenerative disorders (n = 100). Results of factor analysis and Mokken scaling analysis were compared. Results: Principal component analysis revealed one factor for each group. Confirmatory factor analysis found that the one-factor model fit two samples poorly. Mokken analyses revealed different item ordering in terms of difficulty for each group. Conclusion: The different patterns for each diagnostic group could aid in the separation of these different types of dementia.

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.

Objectives. This study attempts to introduce the Driving Locus of Control (DLoC), a method focused on the internal or external source of attribution of the driving behaviour, to the Czech context. This study also relates DLoC to attitudes towards autonomous vehicles (AVs). Participants and setting. Out of the general population, 59 inquirers personally interviewed (CAPI) 1 065 respondents (49% women) in the age range between 15 and 92 years (M = 50, SD = 17). The respondents were sampled via multistage random sampling procedure, based on the list of addresses in the Czech Republic. Hypotheses. The authors hypothesised to replicate the original two-factor structure of the DLoC Scale and that the higher levels of internal DLoC result in not considering the improvement in traffic safety as the AVs replace human drivers. Statistical analysis. Confirmatory factor analysis was used to analyse the factor structure of DLoC Scale. Hypotheses related to the empirical validity of the method were assessed via structural equation modelling. The reliability of DLoC Scale was calculated in terms of internal consistency (McDonald coefficient). Results. Confirmatory factor analysis revealed reasonably good support for structural validity of the one-dimensional DLoC-CZ15 factor model (χ2 = 426.967, df = 90, CFI = 0.964, TLI = 0.958, SRMR = 0.066, RMSEA = 0.065). In addition, the one-dimensional DLoC-CZ15 factor model showed acceptable internal consistency - ω = 0.9 (95% CI [0.89, 0.91]). The structural equation modelling found a relationship between DLoC and some of the items capturing attitudes towards AVs, too. Study limitations. The analysed data were obtained via interviews between respondents and inquirers. As a result, the study does not contain indicators of empirical validity measured by a methodologically different approach, such as an observation of driving behaviour.

Test Result

This study tries to explore the factors contributing to the source credibility of celebrities as brand endorsers and, subsequently, develops a conceptually integrated scale for the same in Indian perspective. To conduct an empirical investigation, a survey is conducted consisting of 432 participants. In this study, exploratory factor analysis (EFA) followed by confirmatory factor analysis (CFA) has been con-ducted. Exploratory factor analysis resulted in three factors or dimensions. All the indicators are strongly loaded into their respective construct. The Cronbach’s alpha, composite factor reliability and variance extracted measure for validity checks are found to be satisfactory. All pairs of inter-construct correlation are found to be positive and significant. The issue of multicollinearity did not bear a serious threat to the data. Common method effect of Harmen’s one-factor post hoc test result indicates that multidimensional three-factor model fits the data well than the one-factor model. These results are also invariant across different demographic profiles, namely, gender, educational qualification and age.

Background/Aim. In (counter)transference relationship therapist?s interpersonal style, implying the perceived relation of therapist to a client (patient) in terms of control, autonomy, care and positive feedback, has been shown to be important. The aim of our study was to assess the relationship between therapist?s interpersonal style and clients? personality self-reports. Within therapist?s interpersonal style, preliminary validation of the Therapist?s Interpersonal Style Scale has been conducted, which included double translation method, exploratory factor analysis, confirmatory factor analysis, as well as the reliability tests of the derived components. Methods. This research was conducted on a group of 206 clients, attending one of the four psychotherapy modalities: psychoanalysis, gestalt therapy, cognitive-behavioral and systemic family therapy. Beside Therapist?s Interpersonal Style Scale, Big Five Questionnaire and Therapy Benefit Scale were administered, showing good internal consistency. Results. Principal component analysis of therapist?s interpersonal style singled out two components Supportive Autonomy and Ignoring Control, explaining 42% of variance. Two-factor model of the therapist?s styles was better fitted in confirmatory factor analysis than the original 4-factor model. Structural model showing indirect and direct effects of therapist?s interpersonal styles on selfreports in clients indicates good fitness (?2(12) = 8.932, p = 0.709; goodness-of-fit index = 0.989), with Ignoring Control having direct effect on Stability, Supportive Autonomy on Therapy Benefit, and Therapy Benefit on Plasticity. Conclusion. The results of this study indicate the importance of further research on therapist?s interpersonal style, as well as further validation of the instrument that measures this construct. Besides, a client?s perception that the therapy is being helpful could instigate more explorative and approach-oriented behavior, what indirectly might contribute to a client?s stability.

The accomplishment of any educational system despite the strategic design depends to a large extent on the quality of teachers. Therefore, this study was carried out to determine the internet skills needs of vocational and technology teachers to facilitate students’ learning in Nigeria technical and vocational institutions. The study adopted a survey research design. The population for the study consisted of 215 technology and vocational education teachers from Six (6) south western states of Nigeria. A research question was developed to guide the study. A structured questionnaire was used to collect data from the respondents which was duly validated by experts. Cronbach Alpha reliability technique was used to determine the internal consistency of the questionnaire items at 0.91. Data collected were analysed through Confirmatory factor Analysis (CFA) using Statistics Package for Social Sciences (SPSS) and Analysis Moment of statistics (AMOS). After a preliminary analysis (descriptive), data from respondents were found suitable for inclusion in Confirmatory factor analysis (CFA). The CFA was performed and the results of the analysis support the one-factor model of the internet skills component for facilitating students’ learning. The study found that technology teachers require nine (9) internet proficiencies under investigation. Thus, it was recommended that conferences, workshops, seminars, training and retraining programmes should be organized at regular interval for teachers in order to enhance their competency for the purpose of boosting their performance in teaching

Self esteem merupakan sebuah pembentukan karakter mengenai diri sesorang dan merupakan faktor penting dalam perilaku langsung berkaitan dengan berbagai aspek dalam hidup. Tanpa dibekali self esteem, individu akan mengalami kesulitan untuk mengatasi tantangan hidup maupun untuk merasakan berbagai kebahagiaan dalam hidupnya. Ia juga mengatakan bahwa self esteem mengandung nilai keberlangsungan hidup (survival value) yang merupakan kebutuhan dasar manusia. Hal ini memungkinkan self esteem mampu memberikan sumbangan bermakna bagi proses kehidupan individu selanjutnya, maupun bagi perkembangan pribadi yang sehat. Penelitian ini bertujuan untuk menguji validitas konstruk instrument tersebut. Data dalam penelitian ini subjek adalahsantri yang sedang dalam proses menempuh pendidikan di Pondok Pesantren Ma’hadut Tholabah Babakan, Lebaksiu, Tegal berjumlah 198 orang. Metode yang digunakan adalah Confirmatory Factor Analysis (CFA) menggunakan software LISREL 8.70.Hasil dari penelitian ini menunjukkan bahwa 7 dari 10 item yang ada bersifat unidimensional. Artinya hanya 7 item mengukur satu faktor saja sehingga model satu faktor yang diteorikan oleh rosenberg self esteem scale dapat diterima.Self-esteem is a character formation about someone and is an important factor in direct behavior related to various aspects of life. Without being equipped with self-esteem, individuals will find it difficult to overcome life's challenges and to feel various happiness in their lives. He also said that self-esteem contains the value of survival (survival value) which is a basic human need. This allows self-esteem to be able to contribute meaningfully to the next individual life process, as well as to healthy personal development. This study aims to examine the construct validity of the instrument. The data in this study were subjects who were in the process of taking education at the Ma'hadut Tholabah Babakan Islamic Boarding School in Lebaksiu, Tegal, amounting to 198 people. The method used is Confirmatory Factor Analysis (CFA) using LISREL 8.70 software. The results of this study indicate that 7 out of 10 items are unidimensional. This means that only 7 items measure only one factor so that the one-factor model theorized by Rosenberg's self-esteem scale can be accepted.

The purpose of this research is to develop the Counselor Attitude Scale for Spirituality in Counseling. The study group consists of 386 (253 female, 133 male) counselors. The methods of exploratory and confirmatory factor analyses are used to determine the construct validity of the scale. A single-factor structure consisting of seven items has been obtained as a result of the exploratory factor analysis. The compatibility the one-dimensional model has with the data is tested using confirmatory factor analysis. The single-factor model has been determined to have good fit indexes as a result of the analysis (RMSEA = .04, RMR = .03, GFI = .98, AGFI = .95, CFI = .99, IFI = .99, NFI = .98). Cronbach’s alpha coefficient has been calculated as .89 for the reliability analysis of the scale and the test-retest coefficient as .88; the 27% lower-upper group t values are found to be significant (p<.001). The findings show the developed scale to be psychometrically valid and reliable, and useful for assessing counselors’ attitudes towards spirituality in counseling interactions.
