SynopsisThe Needs for Care Assessment Schedule (NFCAS; Brewin et al. 1987) is an itemized and systematic procedure that aims to evaluate the needs for care of long-term mentally ill patients. The present study pursues reliability and validity related issues with the NFCAS in a different cultural context applying the procedure to 98 severely mentally ill patients belonging to different patient groups: short-term, long-term, in-patient and out-patient.Inter-rater reliability was found to be excellent. The results suggest that a clinician with little practical experience and adequate training may effectively use the procedure. The assessment of clinical relevance suggested that the procedure is both applicable and pertinent to all the patients in the study. Additional guidelines were developed for its use with long-term in-patients.

While most researchers do agree now that situations may have an effect in the assessment of traits, the consequences have been neglected, so far: if situations affect the assessment of traits we have to take this fact into account in studies on reliability and validity of measurement instruments and their application. In the theoretical part of this article we provide a more formal exposition of this point, introducing the basic concepts of latent state–trait (LST) theory. LST theory and the associated models allow for the estimation of the situational impact on trait measures in non‐experimental, correlational studies. In the empirical part, LST theory is applied to three well known trait questionnaires: the Freiburg Personality Inventory, the NEO Five‐Factor Inventory and the Eysenck Personality Inventory. It is shown that significant proportions of the variances of the scales of these questionnaires are due to situational effects. The following consequences of this finding are discussed, (i) Instead of the reliability coefficient, the proportion of variance due to the latent trait, the consistency coefficient, should be used for the estimation of confidence intervals for trait scores, (ii) To reduce the situational effects on trait estimates it may be useful to base such an estimate on several occasions, i.e., to aggregate data across occasions. (iii) Reliability and validity studies should not only be based on a sample of persons representative of those to whom the test will be applied; they should also be conducted in situational contexts representative of the intended applications.

Di era globalisasi ini, sudah menjadi gaya hidup bagi hampir setiap generasi muda dan dewasa untuk bersantai dengan cara menongkrong di café atau kedai kopi. Starbuck merupakan salah satu kedai kopi yang sering dikunjungi anak muda. Penelitian ini bertujuan untuk memprediksi hubungan variabel anteseden (yaitu: kepercayaan merek, afeksi merek, kesesuaian citra diri, dan kesesuaian fungsional) dari loyalitas merek.  Penelitian ini menggunakan pendekatan kuantitatif. Data dikumpulkan melalui survei dengan mengintegrasikan disain sampling bertujuan. Kuesioner didistribusikan secara online dan melibatkan 200 responden. Sebelum data diolah, uji reliabilitas dan validitas dilakukan untuk memastikan indikator yang digunakan adalah andal dan valid. Kemudian, data dianalisis dengan menggunakan model persamaan struktural. Hasil analisis memperlihatkan bahwa terdapat tiga dari empat hipotesis penelitian yang didukung. Secara spesifik, penelitian ini menunjukkan bahwa kepercayaan merek, afeksi merek, dan kesesuaian citra diri merupakan prediktor utama dari loyalitas merek. Pembahasan dan keterbatasan penelitian disampaikan dalam penelitian ini. In this era of globalization, it has become a lifestyle for almost every young generation and adult to relax by hanging out in a café or coffee shop. Starbuck is one of the coffee shops frequented by young people. This study aims to predict the relationship between antecedent variables (namely: brand trust, brand affection, self-image congruence, and functional congruence of brand loyalty. This study uses a quantitative approach. The data were collected through a survey by integrating a purposive sampling design. The questionnaire was distributed online and involved 200 respondents. Before the data is processed, reliability and validity tests are carried out to ensure that the indicators used are reliable and valid. Then, the data were analyzed using structural equation modeling. The results of the analysis show that there are three of the four supported research hypotheses. Specifically, this study shows that brand trust, brand affection, and self-image congruence are the main predictors of brand loyalty. The discussion and limitations of the research are presented in this study.
