Fractional designs: A simulation study of usefulness in the social sciences

Fractional designs can be extremely useful in social science research, especially when a large number of factors is involved. Reluctance for the use of fractional designs seems to be warranted for two reasons: (1) In the social sciences, the amount of measurement error is often large, which may decrease the power, and (2) higher order interactions are assumed to be nonsignificant, which is difficult to guarantee without sufficient research. This simulation study shows the effects of measurement error and assumption violations under various conditions. It is concluded that fractional designs handle measurement error gracefully and that they are as powerful as a full design when equal degrees of freedom are available. Significant interaction effects can cause serious problems, especially in situations with low or intermediate measurement error, and can lead to erroneous conclusions. Only when estimated confounded effects are clearly not significant, the chance of a wrong decision is reasonably small. Therefore, fractional designs are especially warranted for the exclusion of irrelevant factors. However, we note pitfalls in the use of Version 1.0 of the program Trail Run from SPSS, Inc., to implement the procedures.     

An Examination of the Role of Mentees’ Social Skills and Relationship Quality in a School-Based Mentoring Program

Research on youth mentoring highlights the importance of the relationship quality between mentor and mentee; mentoring results in more positive outcomes when the mentee perceives the relationship as satisfying and trustworthy. Research on relationship quality shows that social skills are important for constructing new relationships. However, whereas improved social skills are often one of the main goals of youth mentoring, little is known about the importance of social skills for relationship quality in youth mentoring relations. In this study, we examined whether mentee's pre-intervention social skills were related to mentor–mentee relationship quality as perceived by the mentee, and in turn, if relationship quality was associated with post-intervention social skills. We additionally examined possible gender and age differences in these associations. Data were used from a two-wave study that assessed relationship quality and social skills before and after one semester of mentoring of 390 secondary school students in a school-based mentoring program. Results indicated that relationship quality was positively associated with post-intervention social skills. However, only for young mentees pre-intervention social skills were associated with better relationship quality. Moreover, only for young mentees, relationship quality mediated the association between pre- and post-intervention social skills.     

Assessment of Stress Risks and Learning Opportunities in the Work Organization

Abstract

Organizational innovation and recent European legislation on work organization require instruments, to be used by practitioners, for the assessment of jobs and the redesign of the structure of the division of labour. In The Netherlands the so-called WEBA-instrument (conditions for well-being at work) has been developed to assess stress risks and learning opportunities. The foundation of the instrument refers to the Dutch modern sociotechnical systems theory, the Karasek demand-control theory and the German action regulation theory. Its application is becoming widespread because, among other reasons, this instrument is supported by the Labour Inspectorate of The Netherlands. Besides a presentation of the instrument and its foundation, some examples will be given and some theoretical and practical problems discussed.     

The Importance of Resources and Security in the Socio-Economic Integration of Refugees. A Study on the Impact of Length of Stay in Asylum Accommodation and Residence Status on Socio-Economic Integration for the Four Largest Refugee Groups in the Netherlands

In many European countries, including the Netherlands, refugees stay in asylum accommodation pending a decision on their asylum request. While it seems evident that the lack of resources and insecurity about the future experienced during this stay will impact refugees’ subsequent ability to integrate with the host society, so far this has hardly been studied in an extensive way. Also, the type of residence status granted can be a source of insecurity that impacts their integration. Previous studies on refugee integration have already shown the impact of pre-migration stressors such as traumatic experiences on mental health and integration. In this study, we use a large-scale dataset containing detailed information on about 4,000 refugees to show that also post-migration stressors affect mental health and hinder the socio-economic integration of the four largest refugee groups in the Netherlands: Afghan, Iraqi, Iranian and Somali.     

“I Need to Do This on My Own” Resilience and Self-Reliance in Urban At-Risk Youths

ABSTRACT

This qualitative study investigates urban at-risk youths’ perspectives on their multiproblem situations and explores their needs for support. Semi-structured interviews were conducted with 23 at-risk youths with varied (externalizing) problems and risk factors. The data analysis was carried out using an inductive thematic approach. Four main themes emerged: desistance from delinquent behavior, need for self-reliance, negative experiences in social relationships and need for support. The participants indicated a strong need to be(come) self-reliant, which was visible in their statements on independence, coping with problems and reluctance to seek or accept help, also regarding desistance from crime. For some, this need for self-reliance seemed to be accompanied by distrust of others, which appeared related to previous negative experiences in social interactions. The participants seemed more open to support coming from someone with similar characteristics or experiences. The findings suggest that in helping at-risk youths, a delicate balance should be sought between stimulating autonomy and providing the necessary resources for support. A focus on strengthening factors that foster resilience is recommended. Future research could investigate the possible benefits of perceived similarity between youths and their care providers.
