In diesem Beitrag wird die Überprüfung des Assessment-Instruments zur Einschätzung der Wirksamkeit familiärer Strategien (ASF-E) für die Anwendung in Deutschland und der deutschsprachigen Schweiz beschrieben. Das ASF-E ist ein Screening-Instrument für Familiengesundheit, wie sie in der Theorie des systemischen Gleichgewichts definiert ist (Friedemann, 1991). Zunächst wurde das Instrument in den frühen 1990er Jahren in der Schweiz unter Berücksichtigung kultureller Unterschiede ins Deutsche übersetzt. Die vorliegende Testung war die erste in Deutschland und die zweite in der Schweiz. Das Instrument hatte ursprünglich 26 Items, wobei jedes drei Aussagen beinhaltet, die Familienstrategien ausdrücken und von denen die Probanden dasjenige auswählen sollten, das am ehesten auf ihre Familiensituation zutrifft. Die Aussagen sind von 1 bis 3 gestaffelt, wobei der Wert 3 für optimale, zufrieden stellende Gesundheit steht. In Deutschland wurde das Instrument von 343 und in der Schweiz von 209 Befragten aus der Gemeinde ausgefüllt, die sowohl unterschiedlichen Alters als auch unterschiedlicher ökonomischer Herkunft waren. Eine Principal Component Analysis mit Varimax Rotation brachte vier Faktoren mit einem Eigenwert > 1 hervor. Acht Items mussten herausgenommen werden, da sie eine unzureichende Verteilung oder zu schwache Faktorladungen aufwiesen. Das endgültige Assessment-Instrument hat 18 Items mit einem akzeptablen Wert für Reliabilität (Cronbach Alpha). Das ASF-E kann in Deutschland und in der Schweiz genutzt werden, um Forschung mit Familien zu begleiten und Familiengesundheit in Verbindung mit Pflegeinterventionen einzuschätzen.

This is a report on the utility of a scale measuring attitudes toward illegal immigrants in two samples from nations that have more people moving out of the country than moving into the country. The Attitude toward Illegal Immigrants Scale was administered to 219 undergraduates from Sofia University in Bulgaria, and 179 undergraduates from Hanoi State University in Vietnam. Results yielded a scale with no sex differences, and acceptable alpha coefficients. Item analysis identified the most contributory and least contributory items, with considerable overlap in the two samples. A principal component analysis with varimax rotation was carried out to examine the structure.

Beberapa penelitian menunjukkan bahwa salah satu faktor yang ikut berperan dalam karier individu adalah Organizational Citizenship Behavior (OCB). OCB mengacu pada perilaku peran ekstra karyawan, yaitu perilaku yang bersifat sukarela dan melampaui ekspektasi peran normal. Berbagai penelitian menunjukkan bahwa pemberlakuan OCB memiliki dampak positif yang kuat pada berbagai hasil kerja individu. Mengingat peran dan dampak OCB dalam organisasi maka perlu disusun instrumen yang tepat untuk mengukur OCB. Penelitian ini dilakukan untuk menyusun instrumen pengukur OCB di kalangan dosen. OCB diukur dari lima dimensi yakni altruism, courtesy, conscientiousness, sportsmanship, dan civic-virtue. Uji reliabilitas dilakukan dengan melihat statistik Cronbach Alpha. Uji validitas ini menggunakan Content Validity Ratio. Validitas isi instrumen diperoleh dengan memberikan kuesioner yang dirancang kepada panelis yang terdiri dari pakar yang berkecimpung di dunia pendidikan dengan bidang psikologi dan manajemen. Pengujian validitas item sebagai pengukur variabel juga dilakukan dengan analisis Principal Component Analysis (PCA). Hasil uji PCA menunjukkan terbentuknya 10 variabel yang dapat digunakan untuk mengukur OCB di kalangan dosen. Total item pernyataan yang membentuk 10 variabel tersebut adalah 36 item pernyataan.

IntroductionThe FMPS is a 35-item self-report questionnaire to measure perfectionism. It evaluates: concern over mistakes/CM, doubts about actions/DA, parental criticism/PC and expectations/PE, personal standards/PS and organization/O.ObjectivesTo develop a shortened version of FMPS and study its internal consistency, the construct, concurrent and divergent validity.MethodsOne hundred and ninety-two university students (78.1% females), aged 19.74 years (sd = 2.10) completed the Portuguese versions of the: FMPS, Hewitt and Flett MPS/H&FMPS, Life Orientation Test Revised/LOT-R, State-Trait Anxiety Inventory/STAI, and Profile of Mood States/POMS.ResultsCorrelations between each item and corrected FMPS total scores/corrected total subscales scores were ≥ 0.20 for the items 13, 15, 25, 31, 35 and 10, 2, 25, and 26, respectively. The internal consistency of FMPS was high (α: .857) with 32 items contributing for this consistency (exceptions: 13, 25 and 31). The principal component analysis of the 35 items with factors varimax rotation was performed. The three items with higher loading in each factor that also contributed to the FMPS reliability were selected for the FMPS shortened version (FMPS-18). The principal component analysis of the 18 items with factors varimax rotation showed that six factors explained 74.6% of FMPS-18 total variance. These factors revealed adequate internal consistency (α: O = 0.740; PC = 0.859; PE = 0.847; PS = 0.726; CM = 0.740; DA = 0.832; total = 0.768). Convergent correlations between FMPS and the matched FMPS-18 scores were 0.839 to 0.971 (all P < .01). Correlations of the FMPS-18 and FMPS with H&F-MPS, STAI, LOT-R and NA/PA scores were of similar significance and valence.ConclusionFMPS-18 is a brief, reliable and valid instrument to measure perfectionism.Disclosure of interestThe authors have not supplied their declaration of competing interest.

AbstractIntroductionConfidentiality is one of the oldest ethical principles in healthcare. However, confidentiality in adolescent healthcare is not a universally-accepted doctrine among scholars. The ethical acceptability of confidential services in adolescents’ healthcare is based on perceptions of adolescent maturity and an appreciation of its importance to adolescents’ access and utilization of healthcare services. Despite legal policies that promote adolescents’ rights, physicians’ attitudes toward adolescent confidentiality can be a determining factor in their ultimate decision to protect adolescents’ confidentiality.MethodA new Attitude towards Adolescent Confidentiality Scale was developed based on the results of a qualitative interview study. This new instrument was administered to a sample of 152 physicians working at school pediatric and gynecology departments in 13 primary healthcare institutions in Belgrade. Principal component analysis was applied to determine the main components of the scale. Reliability was assessed by calculating Cronbach alpha and mean inter-item correlations.ResultsPsychometric analysis of the final 19-item version of the scale showed a high level of reliability (Cronbach alpha of 0.83). Principal component analysis showed four components, which present subscales of the instrument: Confidentiality in clinical situation, Iimportance of confidentiality, Adolescent maturity, and Communication with parents.ConclusionsThe instrument showed satisfactory levels of reliability and validity. The results of the scale dissemination may be a valuable tool for needs assessment for future educational interventions and training programs that will raise physicians’ awareness of the importance of adolescent confidentiality.

Functional Principal Component Analysis (FPCA) is an important dimension reduction technique to interpret the main modes of functional data variation in terms of a small set of uncorrelated variables. The principal components can not always be simply interpreted and rotation is one of the main solutions to improve the interpretation. In this paper, two new functional Varimax rotation approaches are introduced. They are based on the equivalence between FPCA of basis expansion of the sample curves and Principal Component Analysis (PCA) of a transformation of the matrix of basis coefficients. The first approach consists of a rotation of the eigenvectors that preserves the orthogonality between the eigenfunctions but the rotated principal component scores are not uncorrelated. The second approach is based on rotation of the loadings of the standardized principal component scores that provides uncorrelated rotated scores but non-orthogonal eigenfunctions. A simulation study and an application with data from the curves of infections by COVID-19 pandemic in Spain are developed to study the performance of these methods by comparing the results with other existing approaches.

Background: Accurate and reliable self-report measurement tools examining depressive symptoms are scant in child psychiatry. This study assessed the psychometric properties of the Chinese Version of the Quick Inventory of Depressive Symptomatology-Self-Report (C-QIDS-SR) in depressed adolescents in China.Methods: Adolescents with major depressive episodes or bipolar depressive episodes were assessed using the C-QIDS-SR. The structure validity of the C-QIDS-SR was estimated using principal component analysis with varimax rotation.Results: A total of 246 depressed adolescents were included in the study. Cronbach's alpha was 0.77. The correlation coefficient between the baseline and endpoint assessments was 0.49 (p &lt; 0.001), whereas, the correlation coefficient between the C-QIDS-SR and the Hamilton Rating Scale for Depression−17 items (HAMD-17) was 0.63 (p &lt; 0.001). Principal component analysis with varimax rotation demonstrated the unidimensional structure of the C-QIDS-SR.Conclusion: The C-QIDS-SR is a reliable and valid instrument with acceptable psychometric properties to measure depressive symptoms in adolescents.

Background: The Intermittent Claudication Questionnaire (ICQ) is a short questionnaire for the assessment of health-related quality of life (HRQOL) in patients with intermittent claudication (IC). The objective of this study was to translate the ICQ into German and to investigate the psychometric properties of the German ICQ version in patients with IC. Patients and methods: The original English version was translated using a forward-backward method. The resulting German version was reviewed by the author of the original version and an experienced clinician. Finally, it was tested for clarity with 5 German patients with IC. A sample of 81 patients were administered the German ICQ. The sample consisted of 58.0 % male patients with a median age of 71 years and a median IC duration of 36 months. Test of feasibility included completeness of questionnaires, completion time, and ratings of clarity, length and relevance. Reliability was assessed through a retest in 13 patients at 14 days, and analysis of Cronbach’s alpha for internal consistency. Construct validity was investigated using principal component analysis. Concurrent validity was assessed by correlating the ICQ scores with the Short Form 36 Health Survey (SF-36) as well as clinical measures. Results: The ICQ was completely filled in by 73 subjects (90.1 %) with an average completion time of 6.3 minutes. Cronbach’s alpha coefficient reached 0.75. Intra-class correlation for test-retest reliability was r = 0.88. Principal component analysis resulted in a 3 factor solution. The first factor explained 51.5 of the total variation and all items had loadings of at least 0.65 on it. The ICQ was significantly associated with the SF-36 and treadmill-walking distances whereas no association was found for resting ABPI. Conclusions: The German version of the ICQ demonstrated good feasibility, satisfactory reliability and good validity. Responsiveness should be investigated in further validation studies.
