The short version of the Oxford-Liverpool Inventory of Feelings and Experiences (sO-LIFE) is a widely used measure assessing schizotypy. There is limited information, however, on how sO-LIFE scores compare across different countries. The main goal of the present study is to test the measurement invariance of the sO-LIFE scores in a large sample of non-clinical adolescents and young adults from four European countries (UK, Switzerland, Italy, and Spain). The scores were obtained from validated versions of the sO-LIFE in their respective languages. The sample comprised 4190 participants (M = 20.87 years; SD = 3.71 years). The study of the internal structure, using confirmatory factor analysis, revealed that both three (i.e., positive schizotypy, cognitive disorganisation, and introvertive anhedonia) and four-factor (i.e., positive schizotypy, cognitive disorganisation, introvertive anhedonia, and impulsive nonconformity) models fitted the data moderately well. Multi-group confirmatory factor analysis showed that the three-factor model had partial strong measurement invariance across countries. Eight items were non-invariant across samples. Significant statistical differences in the mean scores of the s-OLIFE were found by country. Reliability scores, estimated with Ordinal alpha ranged from 0.75 to 0.87. Using the Item Response Theory framework, the sO-LIFE provides more accuracy information at the medium and high end of the latent trait. The current results show further evidence in support of the psychometric proprieties of the sO-LIFE, provide new information about the cross-cultural equivalence of schizotypy and support the use of this measure to screen for psychotic-like features and liability to psychosis in general population samples from different European countries.

This study main purpose was the validation of both French and German versions of a Perceived Neighborhood Social Cohesion Questionnaire. The sample group comprised 5065 Swiss men from the "Cohort Study on Substance Use Risk Factors." Multigroup Confirmatory factor analysis showed that a three-factor model fits the data well, which substantiates the generalizability of Perceived Neighborhood Social Cohesion Questionnaire factor structure, regardless of the language. The Perceived Neighborhood Social Cohesion Questionnaire demonstrated excellent homogeneity (α = 95) and split-half reliability (r = .96). The Perceived Neighborhood Social Cohesion Questionnaire was sensitive to community size and participants' financial situation, confirming that it also measures real social conditions. Finally, weak but frequent correlations between Perceived Neighborhood Social Cohesion Questionnaire and alcohol, cigarette, and cannabis dependence were measured.

The purpose of this study is the adaptation and validation of the"Survey Work-Home Interaction NijmeGen" (SWING) developed by Geurts and colleagues to Spanish speaking countries (SWING-SSC). In order to analyze the questionnaire"s psychometric properties, confirmatory factor analysis (CFA) was carried out with a sample of 203 employees from various Spanish-speaking countries. Criterion related validity was tested by examining correlations between the SWING-SSC, and the theoretically relevant variables: health, role conflict, role clarity and supervisor support. Finally, reliability was tested analyzing the internal consistency of the scales. The analyses carried out indicate that SWING-SSC has good psychometric properties. In addition, the present results support the relation of the construct with health, role conflict, role clarity, and supervisor support. This study offers evidence for a sound work-life balance measure that contributes to the encouragement adequate conditions in the workplace, to reduce the conflict between the two spheres of professional and personal life, and to enhance positive relationships.

The psychometric properties of the Personal Wellbeing Index are analyzed on a Spanish and Portuguese adolescent sample. We test the reliability of the scale using Cronbach’s alpha. And complementarily we analyze the item-total correlations in the different wellbeing domains included. We execute an exploratory factor analysis (principal components) and a multigroup Confirmatory Factor Analysis (CFA). The results show that Cronbach’s alpha is 0.79 for the Chilean version and in the Brazilian version is 0.78 confirming adequate levels of reliability found in previous studies. Correlations between fields of well-being shows values ranging between 0.224 and 0.496 for Chile and from 0.24 to 0.46 for Brazil. The results are similar to those obtained in other countries. The monofactorial structure of the scale is cinfirmed, also the adjustment to the scale structure to the data of the two samples and the comparability of means of global indices. The results suggest the existence of other well-being domains that had not been considered in the original proposal of the scale

On this instrumental study we intend to analyse the factorial structure of the Screen for Child Anxiety Related Emotional Disorders (SCARED) in a Spanish sample using exploratory and confirmatory factorial analysis. As a second objective we intend to develop a short form of it for rapid screening and, finally, to analyze the reliabilities of both questionnaires. The SCARED was administered to a community sample of 1,508 children aged between 8 and 12 years. The sample was randomly split using half for the exploratory analysis and the other half for the confirmatory study. Furthermore a reduced version of the SCARED was developed using the SchmidLeiman procedure. Exploratory Factor Analysis yielded a four factor structure comprised of Somatic/panic, Generalized anxiety, Separation anxiety and Social phobia factors This structure was confirmed using Confirmatory Factor Analysis. The four factors, the full scale and the short scale showed good reliabilities. The results obtained seem to indicate that the Spanish version of the SCARED has good internal consistency, and along with other recent results, has a structure of four related factors that replicates the dimensions proposed for anxiety disorders by the DSM-IV-TR

In this paper we set out a confirmatory factor analysis model relating the values adolescents and their parents aspire to for the child’s future. We approach a problem when collecting parents’ answers and analysing paired data from parents and their child: the fact that in some families only one parent answers, while in others both meet to answer together. In order to account for differences between one-parent and two-parent responses we follow a multiple group structural equation modelling approach. Some significant differences emerged between the two and one answering parent groups. We observed only weak relationships between parents’ and children’s values

This study focuses on observing how Finnish companies execute their new product launch processes. The main objective was to find out how entry timing moderates the relationship between launch tactics (namely product innovativeness, price and emotional advertising) and new product performance (namely sales volume and customer profitability). The empirical analysis was based on data collected in Lappeenranta University of Technology. The sample consisted of Finnish companies representing different industries and innovation activities. Altogether 272 usable responses were received representing a response rate of 37.67%. The measures were first assessed by using exploratory factor analysis (EFA) in PASW Statistics 18 and then further verified with confirmatory factor analysis (CFA) in LISREL 8.80. To test the hypotheses of the moderating effects of entry timing, hierarchical regression analysis was used in PASW Statistics 18. The results of the study revealed that the effect of product innovativeness on new product sales volume is dependent on entry timing. This implies that companies should carefully consider what would be the best time for entering the market when launching highly innovative new products. The results also depict a positive relationship between emotional advertising and new product sales volume. In addition, partial support was found for a positive relationship between pricing and new product customer profitability.

Tutkimuksen päätarkoituksena on selvittää lukio-opiskelijoiden käsityksiä oppimisensa itsesäätelystrategioista. Lukiokoulutuksessa toteutetut muutokset kuten valinnanmahdollisuuksien lisääntyminen ovat antaneet lukio-opiskelijoille kasvaneen mahdollisuuden omanlaisensa lukio-opiskelupolun suunnitteluun ja yksilölliseen tavoitteenasetteluun. Työssä tarkastellaan myös lukio-opiskelijoiden opintojen kulkua, erilaisia opiskeluodotuksia ja niiden toteutumista sekä näiden yhteyttä itsesäätelyyn. Tutkimus toteutettiin seurantatutkimuksena, jossa kyselylomakkeilla kerättiin tietoa syksyllä 2004 Turun kaupungin suomenkielisissä päivälukioissa (10 koulua) opintonsa aloittavilta opiskelijoilta kahdesti; ensimmäisenä ja kolmantena opiskeluvuotena. Tutkimuksessa oli mukana 245 opiskelijaa, 142 tyttöä ja 103 poikaa. Tutkimuksen vastausprosentti oli 84 %. Kyselylomakkeiden itsesäätelyä ja oppimisorientaatioita koskevat kysymykset pohjautuivat Jan Vermuntin ILS-oppimistyylimittariin (Inventory of Learning Styles) (Vermunt 1994; 1996). Lisäksi haastateltiin 15 tutkimuksessa mukana ollutta opiskelijaa. Kyselylomakeaineisto analysoitiin ristiintaulukoinneilla, korrelaatiokertoimilla, t-testeillä ja erilaisilla varianssianalyyseillä. Itsesäätelystrategiamittarin neljän summamuuttujan oletus testattiin erikseen mittauksissa 1 ja 2 konfirmatorisen faktorianalyysin avulla. Tutkimuksessa identifioitiin klusterianalyysillä tehdyssä ryhmittelyssä neljä erilaista lukio-opiskelijaryhmää: menestyvät navigoijat, tavalliset tasapainoilijat, säätelemättömät kulkeutujat ja ylikuormittuneet avuntarvitsijat. Navigoijille on tyypillistä niin prosessin/ tulosten kuin sisällön suhteen korkea itsesäätely. Tyypillinen piirre navigoijien kohdalla on myös ulkoisen säätelyn korkea taso. Avuntarvitsijat eroavat muista ryhmistä selkeästi korkeampien puutteellisten säätelystrategioidensa perusteella, vaikka heidän itsesäätelynsä on suhteellisesti niihin ja muihin ryhmiin nähden melko korkealla tasolla. Tasapainoilijat sijoittuvat itsesäätelyn ja ulkoisen säätelyn osalta ryhmien keskitasolle. Kulkeutujien itsesäätely samoin kuin ulkoinen säätely ovat ryhmien matalinta tasoa. Tuloksista nähdään, että kehittyneemmällä itsesäätelyllä on selvä yhteys lukio-opintojen sujuvuuteen ja opintomenestykseen, mutta noin kolmasosalle opiskelijoista itsesäätelevä, suunnitelmallinen tavoitteenasettelu on vaikeaa. Navigoijilla ja tasapainoilijoilla opiskelu on sekä heille itselleen mielekästä että ulkoisesti arvioituna tehokasta. Joidenkin opiskelijoiden erityisesti avuntarvitsijoiden ja kulkeutujien keskuudessa opintojen kulku sen sijaan hapuilee. Lukiolaisten opiskeluun kohdistuvien odotusten voidaan tämän tutkimuksen tuloksen perusteella katsoa ennustavan todellista opintojen kulkua ja opintomenestystä melko hyvin. Eroja on sekä tavoitetasossa, opiskeluprosessiin liittyvissä kokemuksissa että jatko-opintosuunnitelmissa ja ne ovat yhteydessä sukupuoleen, isän sosioekonomiseen asemaan, erikoislinjalla opiskeluun sekä lukion alun itsesäätelyryhmiin.

The focus of this dissertation is the motivational influences on transfer in higher education and professional training contexts. To estimate these motivational influences, the dissertation includes seven individual studies that are structured in two parts. Part I, Dimensions, aims at identifying the dimensionality of motivation to transfer and its structural relations with training-related antecedents and outcomes. Part II, Boundary Conditions, aims at testing the predictive validity of motivation theories used in contemporary training research under different study conditions. Data in this dissertation was gathered from multi-item questionnaires, which were analyzed differently in Part I and Part II. Studies in Part I employed exploratory and confirmatory factor analysis, structural equation modeling, partial least squares (PLS) path modeling, and mediation analysis. Studies in Part II used artifact distribution meta-analysis, (nested) subgroup analysis, and weighted least squares (WLS) multiple regression. Results demonstrate that motivation to transfer can be conceptualized as a three-dimensional construct, including autonomous motivation to transfer, controlled motivation to transfer, and intention to transfer, given a theoretical framework informed by expectancy theory, self-determination theory, and the theory of planned behavior. Results also demonstrate that a range of boundary conditions moderates motivational influences on transfer. To test the predictive validity of expectancy theory, social cognitive theory, and the theory of goal orientations under different study settings, a total of 17 boundary conditions were meta-analyzed, including age; assessment criterion; assessment source; attendance policy; collaboration among trainees; computer support; instruction; instrument used to measure motivation; level of education; publication type; social training context; SS/SMC bias; study setting; survey modality; type of knowledge being trained; use of a control group; and work context. Together, the findings cumulated in this thesis support the basic premise that motivation is centrally important for transfer, but that motivational influences need to be understood from a more differentiated perspective than commonly found in the literature, in order to account for several dimensions and boundary conditions. The results of this dissertation across the seven individual studies are reflected in terms of their implications for theory development and their significance for training evaluation and the design of training environments. Limitations and directions to take in future research are discussed.

The main objective of this Master’s Thesis was to examine the interrelations of service quality and relationship quality (customer satisfaction, trust and commitment), and find out are they antecedents for customer loyalty in business-to-business context. Literature review revealed some research gaps concerning these focal concepts, which should be studied more closely. The theoretical basis for this research was collected for evaluating a strategic increase of customer’s perceptions of service quality and relationship quality as well as customer loyalty in business-to-business environment, and it was tested empirically in a sample of 164 corporate customers, who responded to the Internet-based survey. The measures, used in the survey, were first assessed by using confirmatory factor analysis (CFA), and then the hypothesized relationships were further verified using structural equation modeling (SEM) in LISREL 8.80. There was found support for a half of the hypothesized construct relations. The results of the research confirm the direct influence of trust and commitment on customer loyalty. Also, service quality turned out to have an indirect impact on customer loyalty through trust. No support, however, was offered for the proposed impact of customer satisfaction on loyalty in this case. The research provides managerially relevant and actionable results that may help service providers execute more specific customer relationship quality strategies that lead to higher customer loyalty.

The intent of this research was to develop a model that describes the extent to which customer behavioral intentions are influenced by service quality, customer satisfaction and customer perceived value in the business-to-business service context. Research on customer behavioral intentions is quite fragmented and no generalized model has been presented. Thus, there was need for empirical testing. This study builds on the services marketing theory and assesses the relationships between the identified constructs. The data for the empirical analysis was collected via a quantitative online survey and a total of 226 usable responses were obtained for further analysis. The model was tested in an employment agency service setting. The measures used in this survey were first assessed by using confirmatory factor analysis (CFA) after which the hypothesized relationships were further verified using structural equation modeling (SEM) in LISREL 8.80. The analysis identified that customer satisfaction played a pivotal role in the model as it was the only direct antecedent of customer behavioral intentions, however, customer perceived value showed a strong indirect impact on buying intentions via customer satisfaction. In contrast to what was hypothesized, service quality and customer perceived value did not have a direct positive effect on behavioral intentions. Also, a contradicting finding with current literature was that sacrifice was argued to have a direct but positive impact on customer perceived value. Based on the findings in this study, managers should carefully think of their service strategies that lead to their customers’ favorable behavioral intentions.

Riskit ja riskittömyys uhkaavat yksilöitä, käsityötä ja yhteiskuntaa. Käsityökasvatukselleon haaste toimia kulttuurissa, joka tavoittelee täyttä riskittömyyttä. Käsityössä kasvatetaan kekseliäisyyteen ja varautumaan sen aiheuttaman riskin kohtaamiseen sekä ottamaan siitä vastuuta. Tämän tutkimuksen tehtävänä on riskivastuullisuuden mallin rakentamiseksi selvittää, kuinka oppilaiden vastuullisuus selittää riskirajaa käsityön turvallisuuskasvatuksen kulttuurissa. Välinearvojen saavuttamiseksi on siedettävä välineriskiä, joka ei ylitä turvallisuuskulttuurin riskirajaa. Välinearvot ovat välineiden laatua lisääviä ominaisuuksia, joilla pyritään peittämään välineriskejä. Siedettävän riskin rajan ratkaisemiseen tarvitaan tietoa käsityön tuottamisesta ja todellisuutta havainnoivien tiedonalojen tietoa. Viime kädessä ratkaisu tehdään rakentavalla ajattelulla, johon kuuluu välinearvojen tavoittelua ohjaava käsityötaju ja välineriskeihin varautumista ohjaava turvallisuustaju. Käsityössä onnistuminen kannustaa kohti uusia haasteita ja epäonnistumisen riski asettuu mittasuhteisiinsa. Kekseliäässä käsityön kulttuurissa kokeillaan omia ja ympäröivän todellisuuden mahdollisuuksia ottamalla oivaltaen riskejä, jotka saavat aikaan rakentavan kokemuksen riskistä. Käsityö on riskioivallusten oppiaine. Tutkimustehtävän toteuttamiseksi tässä tutkimuksessa rakennetaan uusi riskivastuullisuuden malli, jossa vastuullisuus selittää riskirajaa. Mallin vastaavuutta selvitetään valtakunnallisesti peruskoulun käsityön 6. ja 9. luokan käsityön opetuksessa (n = 393). Aineisto on analysoitu rakenneyhtälöanalyysein konfirmatorisella faktorianalyysilla ja polkumallinnuksella. Tutkimusaineisto ja riskivastuullisuuden malli vastaavat toisiaan. Vastuullisuuden selitysosuus turvallisuustajun ja käsityötajun ratkaisemasta riskirajasta on mallin mukaan 35 %. Oppilaat osoittivat tuntevansa oman tuottamisensa vaikutuksia ja vastuuta niistä. Vastuullisuus osoittautui tärkeäksi riskirajan selittäjäksi, joten käsityön turvallisuuskasvatuksen kulttuuri voi kohota uudelle tasolle riskivastuulliseksi. Käsityön turvallisuuskasvatus on kokonaisvaltaista turvallisuustajun kasvatusta. Riskivastuullisuus luo turvallisuuskulttuuriin yhteisen käsityksen siedettävän riskin rajasta. Oppilaiden mahdollisuuksia kekseliääseen tutkivaan tuottamiseen on vahvistettava eikä rajoitettava. Riskivastuullisessa käsityön turvallisuuskasvatuksen kulttuurissa opettajan tehtävänä ei ole estää mitään tapahtumasta vaan saada mahdollisimman paljon tapahtumaan, sillä vastuullisuus kasvaa vastuuta ottamalla. Se on kasvatuksen – käsityökasvatuksen – keino turvallisuustyössä.

The thesis aims to build a theoretical model to explain consumer investment intentions in stocks and investment funds. The model examines the relationships between subjective investment knowledge, expected sacrifice, expected investment value, compatibility, perceived behavioral control and investment intentions. The data was collected via web-based survey and consisted of 45- to 65-year-old Finnish consumers (n=154). Confirmatory factor analysis (CFA), structural equation modeling (SEM) and t-tests were applied in analyzing the data. The results suggest that among average household consumers expected investment value consists of three dimensions, namely, economic, functional, and emotional, whereas expected sacrifice consists of effort, financial risk, source risk, and psychological risk. Two structural models were assessed, one for stock investments and one for investment funds. Whereas the models presented somewhat different outcomes, in both models compatibility had an essential role in explaining consumer investment intentions. Compatibility was affected by expected investment value and expected sacrifice. Subjective investment knowledge impacted consumers’ evaluations of the value and sacrifices. The effect of perceived behavioral control on investment intentions was rather small, however significant. Moreover, the results suggest that there are significant differences between consumers with no investment experience and consumers with investment experience in subjective investment knowledge, the dimensions of expected sacrifices and expected investment value, perceived behavioral control, compatibility and investment intentions.

This thesis tested a path model of the relationships of reasons for drinking and reasons for limiting drinking with consumption of alcohol and drinking problems. It was hypothesized that reasons for drinking would be composed of positively and negatively reinforcing reasons, and that reasons for limiting drinking would be composed of personal and social reasons. Problem drinking was operationalized as consisting of two factors, consumption and drinking problems, with a positive relationship between the two. It was predicted that positively and negatively reinforcing reasons for drinking would be associated with heavier consumption and, in turn, more drinking problems, through level of consumption. Negatively reinforcing reasons were also predicted to be associated with drinking problems directly, independent of level of consumption. It was hypothesized that reasons for limiting drinking would be associated with lower levels of consumption and would be related to fewer drinking problems, through level of consumption. Finally, among women, reasons for limiting drinking were expected to be associated with drinking problems directly, independent of level of consumption. The sample, was taken from the second phase of the Niagara Young Aduh Health Study, a community sample of young adult men and women. Measurement models of reasons for drinking, reasons for limiting drinking, and problem drinking were tested using Confirmatory Factor Analysis. After adequate fit of each measurement model was obtained, the complete structural model, with all hypothesized paths, was tested for goodness of fit. Cross-group equality constraints were imposed on all models to test for gender differences. The results provided evidence supporting the hypothesized structure of reasons for drinking and problem drinking. A single factor model of reasons for limiting drinking was used in the analyses because a two-factor model was inadequate. Support was obtained for the structural model. For example, the resuhs revealed independent influences of Positively Reinforcing Reasons for Drinking, Negatively Reinforcing Reasons for Drinking, and Reasons for Limiting Drinking on consumption. In addition. Negatively Reinforcing Reasons helped to account for Drinking Problems independent of the amount of alcohol consumed. Although an additional path from Reasons for Limiting Drinking to Drinking Problems was hypothesized for women, it was of marginal significance and did not improve the model's fit. As a result, no sex differences in the model were found. This may be a result of the convergence of drinking patterns for men and women. Furthermore, it is suggested that gender differences may only be found in clinical samples of problem drinkers, where the relative level of consumption for women and men is similar.

Three studies comprised the current research program, in which the major goals were to propose and validate empirically the proposed two-level (universal and culture-specific) model of both autonomy and relatedness, as well as to develop reliable and valid measures for these two constructs. In Study 1, 143 mainland Chinese adolescents were asked open-ended questions about their understanding of autonomy and relatedness in three social contexts (peer, family, school). Chinese youth’s responses captured universal and culturally distinctive forms of autonomy (personal vs. social) and relatedness (accommodation vs. distinctiveness), according to a priori criteria based on the theoretical frameworks. Also, scenarios designed to reflect culture-specific forms of autonomy and relatedness suggested their relevance to Chinese adolescents. With a second sample of 201 mainland Chinese youth, in Study 2, the obtained autonomy and relatedness descriptors were formulated into scale items. Those items were subject to refinement analyses to examine their psychometric properties and centrality to Chinese youth. The findings of Study 1 scenarios were replicated in Study 2. The primary goal of Study 3 was to test empirically the proposed two-level (universal and culture-specific) models of both autonomy and relatedness, using the measures derived from Studies 1 and 2. A third sample of 465 mainland Chinese youth completed a questionnaire booklet consisting of autonomy and relatedness scales and scenarios and achievement motivation orientations measures. A series of confirmatory factor analysis (CFA) autonomy and relatedness measurement models (first-order and second-order), as well as structural models linking culture-specific forms of autonomy and relatedness and achievement motivation orientations, were conducted. The first-order measurement models based on scale and scenario scores consistently confirmed the distinction between personal autonomy and social autonomy, and that of accommodation and distinctiveness. Although the construct validity of the two culture-specific forms of autonomy gained additional support from the structural models, the associations between the two culture-specific forms of relatedness and achievement motivation orientations were relatively weak. In general, the two-level models of autonomy and relatedness were supported in two ways: conceptual analysis of scale items and second-order measurement models. In addition, across the three studies, I explored potential contextual and sex differences in Chinese youth’s endorsement of the diverse forms of autonomy and relatedness. Overall, no substantial contextual variability or sex differences were found. The current research makes an important theoretical contribution to the field of developmental psychology in general, and autonomy and relatedness in particular, by proposing and testing empirically both universal and culture-specific parts of autonomy and relatedness. The current findings have implications for the measurement of autonomy and relatedness across social contexts, as well as for socialization and education practice.
