Foreign Policy Attitudes

Previous studies of Western European foreign policy attitudes rely almost exclusively on single-item measures, such as support for defence spending, support for the new missiles in Europe, opinions on NATO, and so on. This article, using a multi-country data set, aggregates several survey items and explores the manner in which Europeans structure their attitudes towards one aspect of foreign policy: Atlantic co-operation. A factor analysis uncovers two underlying conceptual dimensions: military and non-military co-operation. These dimensions provide the axes to construct a four-fold typology of viewpoints, consisting of Atlanticists, Military Allies, Dovish Partners and Isolationists. Respondents are classified within this typology, and the European-wide and cross-national distributions of opinion are presented. The highest support for Atlantic co-operation is found among the West Germans, and the lowest is found among the French.

SummaryThe paper discusses the relevance of sufficient psychometric standards for dementia rating scales. The concurrent, convergent and construct validity of the Mini Mental State Examination (MMSE), the Alzheimer's Disease Assessment Scale (ADAS) and the CAMCOG are assessed. The Clinical Global Impressions and the Global Deterioration Scale are used as global scales. The concurrent and convergent validity are satisfactory. The construct validity expressed by the Cronbach and Loevinger coefficient are very good for all scales and subscales. The Mokken's single item coefficients show that the MMSE has the best individual hierarchical fit, the item reading can be left out. The ADAS is less uni-dimensional, eight items can be left out. The CAMCOG consists of too many items to apply the Mokken's single item coefficients or the Loevinger coefficient. Instead, the CAMCOG subscales are analyzed. This results in a possible reduction of the CAMCOG by 30 items to a total of 35 items. The factor analysis reveals two factors in both the MMSE and the ADAS while the number of observations does not allow a factor analysis of the CAMCOG to be performed.

Item Scale

Purpose The purpose of this study is to identify clinically meaningful groups of Health of the Nation Scales Learning Disabilities (HONOS-LD) single-item scales that might be used as short scales that are more reliable than single-item scale scores and more focused than the sum of scale scores. The single-item scales are likely to be unreliable in many applications. The sum of scale scores is a heterogeneous measure that is not a good representative of any specific difficulties that people who have intellectual disabilities may have and the effects of interventions on any specific difficulties may be masked by fluctuations in the ratings of other scales. Design/methodology/approach A total of 2,109 pseudonymised complete HONOS-LD ratings were factor-analysed using principal factor extraction and oblimin rotation. Three-, four- and five-factor rotated patterns were examined. Findings Three factors that each have three or more strong loadings (≥|0.50|) were identified that jointly included 11 single-item scales: one representing problems with cognitive competencies, one representing depressive phenomena or other mood problems and one representing problems with social competencies. A weaker factor that represents behaviour that challenges services is indicated; it includes five single-item scales. Both the cognitive competencies and social competencies groups of items were also reported in a previous study by Skelly and D’Antonio (2008) and may be stable. The present study’s factor representing behavioural difficulty has some similarity to Skelly and D’Antonio’s “functional behaviour and attachment disturbance” group. In other respects, the present study and the previous study differ. Research limitations/implications The outcomes of these factor analyses indicate that some of the single-item scales can be combined into groups. However, the specific groups found in this study must be regarded as possibly unstable because of the likelihood of weak inter-rater reliability in HONOS-LD data and differences between this analysis and Skelly and D’Antonio’s. Further research is needed to support or modify them. Practical implications The cognitive competence and social competence groups of items may be used as subscales if they are convenient. The groups representing mood and behavioural problems should be supported by further research before being used. Originality/value This is the second published factor analysis of the HONOS-LD and includes a much larger data set than the first. It has some similarities to and differences from the first and is a further step in the process of identifying useful groupings of HONOS-LD single-item scales.

Validity and reliability of the Bruininks-Oseretsky Test of Motor Proficiency-Short Form were examined through factor analysis, differences in motor proficiency among age groups, and internal consistency. The sample was comprised of 194 children (96 boys and 98 girls) of ages 6 to 11 years. A principal factor analysis solution with varimax rotation produced four factors: Gross and Fine Motor Skills, Eye-Hand Coordination, Balance-Coordination and Speed, and Visual-motor Coordination. The loadings of these factors partially supported the theoretical work of Bruininks. Univariate analysis of variance showed significant differences between age groups either for each single item or for the total score. Correlation coefficients between single-item and total short form were all significant, although some values were relatively small. These results provided positive support for the construction and reliability of the test.

Abstract. Emerging adulthood theory highlights ambivalence about one’s adult status as a distinctive feature of this period. However, most studies that addressed this ambivalence employed rather limited, single-item measures, or measures that focused on specific life domains but addressed them separately. Although existing literature suggests that various life situations are likely to contribute differently to a sense of adulthood, no attempt has been made to date to conceptualize these situations as contexts and to develop a measure that takes them into account. The first study of the present research aims at unveiling the contexts that shape a sense of adulthood by conducting a multiple group exploratory factor analysis on the self-perceived adulthood scale ( Shanahan, Porfeli, & Mortimer, 2005 ). The analyses revealed two factors contributing to a sense of adulthood, which were interpreted as adult and peer contexts. The second study aims at developing a new measure designed to address sense of adulthood in these two contexts. This measure was proven reliable, valid, and stable across three age groups. The present research demonstrates that sense of adulthood is a context-specific feeling. Thus, adult and peer contexts ought to be considered and addressed separately, which has been made possible with our proposed measure.

Moral Domain

This article contributes to the psychology of moral behavior by inquiring into the presence and extent of worrying about moral concerns in one's life relative to worrying about practical concerns. A 20-item questionnaire was developed, mixing eight moral worry questions with twelve ordinary worry items (finances, health) identified in previous research on worry. Factor analysis produced three domains of worrisome thinking: moral concerns, social desirability, and personal and family health. A single item inquiting into worry about not living up to God's expectations did not load onto any other factor and was dropped from further analysis. Internal consistency for the moral worry factor scale was .85. Mean scores for this scale (moral domain) were significantly lower than mean scores for the two practical worry domain factors. Limitations of the study and directions for further research are outlined.

Abstract Background Feelings of fat are common for people with eating disorders, but ways of measuring its intensity are needed. Therefore, our goal was to develop a self-report feelings of fat scale that asked participants to indicate how intensely they currently felt statements such as “I feel fat”. With such a scale we can determine how strongly feelings of fat relate to evidence of disordered eating. Methods We conducted three studies of eating disorders with undergraduate women taking introductory psychology classes. The combined sample was 472 participants. A previous eating disorder diagnosis was self-reported by 33 participants and a current diagnosis by 11. All participants completed the EDE-Q and the seven (Study 1) or nine item (Studies 2 and 3) “State Feelings of Fat” (SFF) scales we developed. Each item asked them to rate the intensity with which they felt statements such “I feel fat” on a seven-point scale from “not at all” to “the most I have ever felt”. Results Both the seven and nine item SFF scales were highly coherent (Cronbach’s α were .94, .95 and .94), but factor analysis supported the seven-item version. We found high correlations between SFF and EDE-Q scores (Study 1: .816; Study 2: .808; Study 3: .841). SFF scores distinguished participants self-reporting no eating disorder diagnosis from those with a former diagnosis, t (361) = 2.33, p = .021, who in turn were distinguished from those with a current diagnosis, t (42) = 2.09, p = .043. Due to the high coherence of the scale, the single item “I feel fat” captured most of the variance in EDE-Q scores (r [472] = .793). Conclusions We have constructed an eating disorders relevant feelings of fat scale. Given that the EDE-Q is considered a valid questionnaire for measuring severity of eating disorders, our findings suggests that feelings of fat are core to the psychopathology of eating disorders. To the extent that EDE-Q scores are stable it also suggests that feelings of fat are surprisingly stable. Furthermore, the single item “I feel fat” alone may capture most of what the EDE-Q measures.

A 30-item questionnaire comprised of Rotter's I-E scale (minus 6 filler items), 6 independent questions derived from the I-E scale, and 1 independent question was administered to 93 college students. Common factor analysis assessed the dimensionality of the I-E scale, and 4 factors were identified. The relationship between the measures of locus of control was assessed, yielding evidence that the single-item measure is a valid alternative brief measure of locus of control.

Entrepreneurship is a tool that the Malaysian Governmentsed to uplift income from the middle-income trap. Therefore, this study aims to identify the predictor factors that influence the inclination of entrepreneurship club members towards the entrepreneurship career by using factor analysis to achieve the Government goal through the Ministry of Education Malaysia.  In other words, this study uses several tests related to validation factor analysis to determine the predictor factors that influence the propensity of entrepreneurship club members towards entrepreneurship careers. This study involved 161 respondents who were members of secondary school entrepreneurship clubs in the State of Terengganu who were randomly selected.  Data gathered were analyzed using Statistical Package for the Social Sciences (SPSS) involving factor analysis and descriptive test. The factor analysis has identified nine predictor factors. The first predictor factor is role model, followed by a barrier, social identity, personality, entrepreneurship skill, social norm, financial, entrepreneurship knowledge, and prosperity. Prosperity was the new predictor factor that was identified using factor analysis in this research. The descriptive test found that the most influenced predictor factor of the entrepreneurship career inclination was finance, followed by personality, social identification, role model, social norm, prosperity, and barrier. Meanwhile, entrepreneurship knowledge was found as a predictor factor which uncertain in influencing the entrepreneurship career inclination among secondary school entrepreneurship club members in the State of Terengganu. The results of this study imply that the Government should give financial factors the priority through the Ministry of Education in formulating policies towards producing more young generation of entrepreneurs in Malaysia because that predictor has a positive impact on secondary school students who were the members of entrepreneurship clubs.
