Development And Validation

In this study, the development and validation of the Environmental Literacy Scale for Adults (ELSA) is explained. The data were collected from 332 adults whose ages ranged from 18 to over 56. The principal component analysis rotated to varimax rotation was used to obtain evidence for the validity of the scale. The scale was composed of 20 items and had three main dimensions: “environmental consciousness”, “environmental anxiety” and “environmental awareness”. A reliability analysis of the instrument revealed Cronbach-Alpha coefficients of 0.881 for the whole of the scale, 0.807 for the first dimension, 0.765 for the second dimension and 0.715 for the last dimension. Considering the results obtained from the validity and reliability studies, it can be asserted that ELSA can be used to determine adults’ views and levels of environmental literacy. Key words: adults, environmental literacy, scale development.

Development And Validation

We administered a 42-item smoking behaviour questionnaire to 150 adult smokers (75 men and 75 women), 18 to 70 years old ( M = 37.1 yr., SD = 12.2). A principal component analysis of their responses followed by varimax rotation yielded four factors accounting for about 52% of the total variance: dependence, social integration, regulation of negative affect, and hedonism. Some sociodemographic and dispositional characteristics of the smokers predict these four dimensions. The predictors of each smoking dimension are quite different for male and female smokers.

This paper gives an account of the consequences of the procedure of EFA (exploratory factor analysis) invoking online risks as well as harm information acquired by an overview of 443 adolescents in Bangladesh. The information was gathered utilizing a 42-item, adjusted Likert survey investigating the critical variables. PCA (Principal Component Analysis) with Varimax rotation was chosen by the researcher to accomplish it. Based on data, the procedure took out the crucial factors social, religiosity, psychological, online risks as well as harm. 65.594% of the variance was clarified by these nine dimensions together. The procedure of reliability analysis generated internal consistency estimates which may be considered acceptable. The range was found from 0.625 which belongs to Emotional Problems to 0.930 which belongs to Online Risks. These discoveries give comprehensive justification to build the legitimacy for the items. The presence of the components influencing altogether the young people online in Bangladesh has been identified as well.

The construct validity and reliability of the 1987 Perceived Physical Competence Scale of Lintunen were examined to assess the applicability of the instrument for use with adolescents with disabilities. Subjects were 51 girls and 34 boys ( M age = 15.1 yr.) from several schools in central Finland. Principal component factor analysis with varimax rotation yielded the same two factors for adolescents with disabilities as reported for nondisabled adolescents in the related literature. Cronbach alphas for the two factors were .89 and .56. It was concluded that the scale is an appropriate measure for adolescents with disabilities. Statistical analysis indicated no gender differences for adolescents with disabilities. When compared with nondisabled groups in the related literature, these adolescents had perceived fitness similar to nondisabled peers but significantly lower than that of athletes without disabilities.

An ecologically valid appraisal of students' problem behaviors must include assessment of the teacher's role as perceiver on various levels. This study analyzes the teacher manageability construct, examining educators' beliefs about their ability to manage 39 generally maladaptive behaviors within their own classroom. To address measurement limitations of previous investigations (including nonfactor analytic clustering of behaviors), a principal component analysis followed by a varimax rotation was administered on teacher manageability ratings (N = 182). This statistical analysis yielded nine component subtests (the Teacher Manageability Scale) and demonstrated that by changing the method used to group behaviors, you also modify the structure of a teacher checklist. Lack of Communication was identified as the most difficult behavior to manage. Implications for professionals working with students identified as behaviorally disordered and for future research are discussed.

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.

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.

Development And Validation

Background and PurposePoor dietary practices are linked to many chronic diseases. The purpose of this validation study was to develop a psychometrically sound instrument that can be administered by health practitioners to measure dietary barriers.MethodsThe Dietary Health Status (DHS) instrument, designed to measure dietary barriers is comprised of items in the National Health and Nutrition Examination Survey-What We Eat in America datasets. Content validity was established for DHS using an expert review process. Principal component analysis (PCA) was then used to assess validity and reliability as determined by Cronbach's alpha values.ResultsThe PCA supported a 10-component solution, explaining 61% of the total variance. Cronbach's alpha was .67 for the entire instrument, ranging from .55 to .87 for the 10 subscales.ConclusionResults suggest the instrument had sufficient construct and internal validity. This exploratory study is an important first step in validating the DHS instrument.

IntroductionThe Hewitt and Flett Multidimensional Perfectionism Scale (H&F-MPS) is one of the most used measures of perfectionism. Their 45-items evaluate self-Oriented (SOP), Self-Prescribed (SPP), and Other Oriented (OOP) perfectionism.ObjectivesTo study the internal consistency and convergent validity of the H&F-MSP13.MethodsOne hundred and ninety-two university students (78.1% females), aged 19.74 years (sd = 2.10; range: 17–28) completed the Portuguese versions of H&F-MPS (Soares et al., 2003) and of Frost et al. MPS (F-MPS) (Amaral et al., 2013). Thirteen items were selected from the Portuguese version of the H&F-MPS, based on their loading in the factor (0.60 and over) (Soares et al., 2003).ResultsThe H&FMPS13 revealed good internal consistency (α = 0.816). The corrected item-total subscale Spearman's correlations were high (from 0.418 to 0.820). The principal component analysis with factors varimax rotation produced three factors, which revealed acceptable/good internal consistency (SOP: explained variance/EV = 35.4%, α = .900; SPP: EV = 16.3%, α = 0.695; OOP: EV = 10.8%, α = 0.709). The correlations between the H&F-MSP13 scores and the matching scores of the H&F-MPS were high (from r = 0.745 to r = 0.945, all P < .01), suggesting that both scales measure similarly the constructs. The H&F-MSP13 and the H&F-MPS total scores demonstrate good convergent validity with the total score of F-MPS, as indicated by the correlations (r = 0.581/r = 0.636, respectively). The correlations similarities between the H&F-MSP13 and H&F-MSP dimensions and the F-MPS dimensions and total scores were also considerable.ConclusionsThe H&F-MSP13 is a valid instrument to measure perfectionism that reveals convergent validity with the F-MPS, retaining the adequate psychometric properties of the H&F-MPS and its administration is less time consuming.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Background Neglect and abuse of older adults are still prevalent in communities of developing countries, a situation that could discourage active and healthy behaviors in community-dwelling older adults. Methods This study used the cross-sectional and correlational approaches to construct a scale measuring neglect and abuse in older adults living in the community. The study population was all (3,211) older adults who were resident in Accra and were part of the database of the Social Security and National Insurance Trust. Participants were 515 individuals who met some inclusion criteria. Three steps were followed to determine an initial set of 11 items, and principal component analysis with varimax rotation and confirmatory factor analysis were used to select relevant items and assess the psychometric properties of the final scale. Results Principal component analysis with varimax rotation yielded a two-factor solution on all 11 items. The first factor extracted was “discrimination and exploitation,” which accounted for a variance of 53.9% out of total variance of 70.8%. The scale had a good internal consistency (Cronbach’s α = .90, factor loading ≥0.50). Confirmatory factor analysis confirmed the two-factor solution and produced satisfactory convergent and discriminant validity. Conclusion It is concluded that 11 items that make up 2 factors are potential indicators of neglect and abuse of older adults at the community level. Finally, neglect and abuse of older people in the community can contribute to an increase or decrease in social activity.

Sensation Seeking Scale

SummaryThis study presents the principal component analysis of Zuckerman’s Sensation Seeking Scale (SSS form IV - 72 items). The results of the analysis of the French form support the existence of the four distinct dimensions of sensation seeking identified by Zuckerman, and replicated in a large number of studies. On the basis of this structure, an abbreviated form of the scale (40 items) has been constructed. It ressembles Zuckerman’s SSS form V. Attention is drawn to items that do not load significantly on the expected factor. The shorter form should be more useful in following-up research on sensation seeking in psychopathology.
