Edible insects (EI) have been consumed as traditional foods in many parts of the globe, but in other regions, they are not readily accepted, particularly in Western countries. However, because EI are suggested to constitute a more sustainable protein food as compared with other sources of animal protein, they can be considered a future food that could help mitigate hunger and malnutrition. Additionally, new gastronomic trends are already targeting this area for exploring new potentialities. The objective of this work was to develop and validate a questionnaire to assess consumers’ perceptions and knowledge about EI in seven different domains: D1. Culture and Tradition, D2. Gastronomic Innovation and Gourmet Kitchen, D3. Environment and Sustainability, D4. Economic and Social Aspects, D5. Commercialization and Marketing, D6. Nutritional Aspects and D7. Health Effects. The 64 items were subjected to item analysis and reliability analysis for validation, and factor analysis was also conducted to identify a grouping structure. The results validated all the items of the seven subscales with high values of Cronbach’s alpha (α = 0.732 for D1, α = 0.795 for D2, α = 0.882 for D3, α = 0.742 for D4, α = 0.675 for D5, α = 0.799 for D6 and α = 0.788 for D7). However, by eliminating 17 items, the final values of the alpha increased in all subscales. Factor analysis with extraction by principal component analysis with varimax rotation extracted 14 factors that explained, in total, 65% of the variance, although the first two factors were the most important (35.7% variance explained). In conclusion, the confirmed usefulness of the questionnaire has been hereby validated for assessing consumer perceptions of and knowledge about EI.

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.

The aim of the study was to construct a normative instrument for measuring organisational citizenship. Based on studies done on organisational citizenship, a framework for identifying the locus of organisational citizenship was developed, and a questionnaire based on this framework was constructed. A factor analysis of the items of the instrument yielded two factors. These factors were interpreted as situational and dispositional loci of organizational citizenship. The two scales were subjected to item analysis and yielded reliability coefficients of 0,946 and 0,908 respectively. The implications of the findings are discussed. Opsomming Die doel van die studie was om ’n normatiewe meetinstrument te konstrueer om organisasieburgerskap te meet. ’n Raamwerk, gefundeer op navorsing oor organisasieburgerskap, is ontwerp en ’n vraelys gebaseer op dié raamwerk is gekonstrueer. ’n Faktorontleding van die items van die skaal het twee faktore opgelewer. Hierdie faktore is as situasionele en disposisionele lokusse van organisasieburgerskap geïnterpreteer. Die skale is vervolgens aan itemontleding onderwerp en het betroubaarhede van 0,946 en 0,908, onderskeidelik, opgelewer. Die implikasies van die bevindinge word bespreek.


The present study verifies the three models on the dimensionality of the construct academic delay of gratification measured with the academic delay of gratification scale prepared by Bembenutty and Karabenick (1996). Sample of the study comprises of 488 professional courses undergraduate students of Muslim minority community (277 boys and 211 girls) from law, engineering, education and pharmacy faculties of Sultan Ul Uloom Education Society, Banjara Hills, Hyderabad, Telangana, India. Exploratory factor analysis was conducted on the responses of the 10 items provided by the sample using SPSS Statistics Ver.23 to extract the factors of the construct. Confirmatory factor analysis conducted using SPSS Amos Ver.23 provided the goodness of fit measures for each of the models. The unidimensional model produced excellent fit indices. Also, one factor model satisfied Gorsuch (1983) criterion to further verify the unidimensional nature of the construct, where the percentage of variance explained by factor 1 was nearly thrice when compared by the percentage of variance explained by the next subsequent factor 2. Monte Carlo principal component analysis method also revealed single factor for this variable. Implications of the findings are discussed.

Individuality, collectivity and locus of control as micro variables of diversity. The principal aim of the study was to construct an instrument to measure individuality and collectivity as micro variables of diversity in the South African context. The Individuality-collectivity Inventory was applied to 326 university students. A factor analysis on 80 items yielded two factors. These factors were interpreted as collectivity and individuality. The two scales were subjected to an item analysis and yielded reliability coefficients of 0,86 and 0,910. A secondary aim of the study was to determine whether any correlation exists between individuality, collectivity and locus of control. The two sub-scales of the Individuality-collectivity Inventory were correlated with the three sub-scales of the Locus of Control Inventory. Statistically significant positive correlations were found to exist between individuality, internal locus of control and autonomy. The implications of the findings on the management of diversity are discussed. Opsomming Die hoofdoel van die studie was om 'n instrument vir die meting van die konstrukte individualiteit en kollektiwiteit as mikroveranderlikes van diversiteit in die Suid-Afrikaanse konteks daar te stel. Die Individualiteit-kollektiwiteitskaal is op 326 universiteitstudente toegepas. 'n Faktorontleding op 80 items het twee faktore tot gevolg gehad/ naamlik Individualiteit en Kollektiwiteit. Die twee skale is vervolgens aan 'n itemontleding onderwerp en betroubaarhede van 0,86 en 0,910 is onderskeidelik opgelewer. 'n Sekondere doelwit van die studie was om te bepaal of daar 'n verband tussen individualiteit, kollektiwiteit en lokus van beheer bestaan. Die twee sub-skale van die Individualiteitkollektiwiteitskaal is met die drie sub-skale van die Lokus van Beheer-vraelys gekorreleer. Statisties beduidende positiewe korrelasies bestaan tussen individualiteit, interne lokus van beheer en outonomie. Die implikasies van die bevindinge vir die bestuur van diversiteit word bespreek.

The Halstead-Reitan Battery, 2 Benton tests and the WISC were administered to a sample of normal children, ages 5 to 8. The results of a principal-component factor analysis indicated that at least nine different areas were being measured. The areas of neuropsychological functioning were: Analytic-Synthetic Visual-motor Ability, Undirected Motor Speed, Verbal Abstract Ability, Resistance to Distraction, Ability to Alternate between Motor Sets, Directed Motor Speed, Environmental Awareness and Judgmental Skills, Sequencing Visual Stimuli, and Checking Behavior. Regression weights and composite score formulae for estimating Ss' scores in these 9 areas were presented. Dimensions were found which correspond to the Verbal-Performance division of the Wechsler test. Five of the factors were found to be relatively independent of psychometric measures of intelligence. Two factors involving higher-order complex skills were also found. The derived factors were related to other factor analytic studies.

The main objective of current research was development of an indigenous Moral Disengagement Scale for Adults (MDS-A) in Urdu language. The subsequent objective was the establishment of reliability of newly developed Scale. Initially an item pool of 116 items was formulated based on Bandura’s model (2002) which was reduced to 106 items and later 92 items after expert’s evaluation and item analysis, respectively. Exploratory Factor Analysis (EFA) was conducted on 92 items scale by administering it on 579 adults (250 men and 329 women), age range of 19-83 years from villages and various educational institutes of district Gujrat, Pakistan. EFA by using Principal Component Analysis with Varimax Orthogonal Rotation resulted in six factor solution of 63 items. Later Confirmatory Factor Analysis (CFA) confirmed the six-factor structure on an independent sample of 413 adults (193 men and 220 women) with age range 19-80 years from Gujrat district, Pakistan. After deletion of 43 items, CFA yielded good model fit indices for final 20 items MDS-A. MDS-A had very satisfactory Cronbach’s alpha reliability and test-retest reliability. MDS-A also demonstrated construct validity in terms of highly significant item-total correlations and subscale-to-scale total correlations. Overall, a reliable and valid scale for measurement of moral disengagement among adults in Pakistani culture is available for further indigenous research and counselling settings.

ABSTRACTBackground: Most people who collect and hoard, and then have difficulty discarding items, do not live in squalor, even though accumulation of hoarded items can make cleaning very difficult. Commonly, people living in squalor accumulate garbage, but relatively few fulfill proposed criteria for “hoarding disorder.” We examined the overlap between hoarding and squalor among people referred because of unacceptable living conditions.Methods: Ongoing collection of data by a Squalor Project team, including ratings on the Environmental Cleanliness and Clutter Scale (ECCS), allowed (1) description of characteristics of cases and (2) examination of ratings of uncleanliness, and of the effect of accumulation of items or material on access within dwellings. Principal component analysis was used to examine latent variables underlying the ECCS.Results: The mean age of the referred occupants (108 male, 95 female) was 61.9 years. The mean ECCS score in 186 rated cases was 18.5. Factor analysis of ECCS data showed a two-factor solution as the most plausible. Factor 1, comprising seven squalor items, accounted for 33.7% of the variance. Factor 2 comprised reduced accessibility and accumulation of items of little value (variance 17.6%). Accumulation of garbage loaded equally on the two factors. High levels of squalor and/or accumulation were recorded in 105 (56%) of the 186 dwellings. One-third scored high on accumulation/hoarding, while 38% scored high on squalor; 15% scored high on both squalor and accumulation. A quarter of those scoring high on squalor scored low on hoarding/accumulation.Conclusions: The ECCS is useful when describing whether referred cases show high levels of squalor, hoarding, or both.

Aim. To determine echocardiographic profiles and their prognostic value using factor analysis in men and women with various types of cardiomyopathies (CMP).Material and methods. The study involved 100 people with CMP — 69 men with a median age of 53 years and 31 women with a median age of 58 years. Among the subjects, six nosological types corresponding to ICD 10 classification were revealed: dilated CMP (DCM), ischemic CMP (ICM), alcoholic CMP, mixed CMP, hypertrophic CMP (HCM) and myocarditis. All persons underwent an echocardiography. Echocardiography results as variables were included in factor analysis. The resulting two factors are presented as the first and second echocardiographic profiles.Results. The first echocardiographic profile was characterized as the degree of myocardial contractile function reduction. A strong association of the first profile with DCM, alcoholic CMP and myocarditis in men (p=0,001) and DCM in women (p=0,05) was obtained. In some individuals with ICM and mixed CMP, there was no association with the first profile. The second echocardiographic profile reflected the degree of myocardial mass increase and had significant differences only in women (p=0,04). A strong correlation with the second profile was observed in HCM, in the majority of women with ICM and in some persons with mixed CMP. Fatal outcomes in men were recorded in patients with ICM (66,7%), alcoholic CMP and myocarditis, and in women with mixed CMP (11,1%).Conclusion. For patients with DCM, myocarditis, and alcoholic CMP, the first echocardiographic profile with a risk of death is characteristic. The second echocardiographic profile was inherent in HCM and was associated with a protective effect in women with ICM. The revealed echocardiographic profiles can be extrapolated to nosological types of CMP in men and women in order to verify the diagnosis and prognosis.

Objective: While much work has gone into developing measures of specific factors in psychotherapy for depression, measures for non-specific factors have been lacking. This paper aims to develop a scale for a non-specific factor called ‘Satisfaction with Therapy and Therapist Scale’. Method: Sixty-seven patients with major depression completed the questionnaires during the fourth session of cognitive therapy. The patients went through an assessment clinical interview using a SCID. They also completed the ATQ, BDI and DAS questionnaires during the fourth session. Results: Principal component factor analysis with varimax rotation showed that the scale possesses two factors, ‘Satisfaction with Therapy’ and ‘Client Evaluation of Therapist’, accounting for 64.7% of the total variance. The alpha Cronbach for the two factors is 0.91 and 0.80 with the total scale alpha at 0.90. The scale also possesses good concurrent and disciminant validity. Conclusion: The Satisfaction with Therapy and Therapist Scale is an adequate measure for measuring a non-specific factor in psychotherapy.

Whereas substantial research in decision-making styles has focused on the theoretical and conceptual definitions, relatively less empirical attention has been paid to the development of its measures. Thus, the purpose of this study is to develop and validate a measure of school principal decision-making styles based on Vroom and Yetton’s (1973) theoretical framework. The researcher initially developed a 40-item pool of the Principal Decision-Making Styles Scale (PDMSS), and then these 40 items were reduced to 27 items after experts’ examination of its content validity. These 27 refined items were administered to 120 primary school principals in the northern states of Malaysia. In order to examine the construct validity of the PDMSS, a factor analysis employing principal component extraction procedures with varimax rotation was used. The factor analysis resulted in a 19-item instrument that measures three extracted decision-making styles, namely, autocratic, participative, and delegation. Additionally, the item analysis showed acceptable internal consistency reliability for the overall and the three specific sub-scales of PDMSS. Moreover, the confirmatory factor analysis revealed that the three identified styles indicate a good model fit.
